Ethics: Life's Performance Evaluation The professionalism of an officer and his department is established through the values and principles he chooses to live and work by. The quality of the individual, the family, the dependent, and the community depends on his code of ethics. The purpose of this paper is to illustrate the importance of high ethical standards in a law enforcement officer's work and in his every day life.

The Verbal Tactics Training program was developed to teach both new Missouri Department of Conservation agent trainees and veteran agents how to use verbal skills as a force option to control or defuse dangerous situations. This program is a key aspect of our sequential training for officer survival. The training is conducted by means of lecture, group discussion, role playing, and simulated field checks. Verbal Tactics training strengthens officer awareness during field confrontations.

The Changing Role of the Florida Wildlife Officer The role of the Wildlife Officer has changed dramatically over the years, due to expanded police powers, growth in population, endangered and threatened species enforcement, and environmental degradation. In South Florida, specialized enforcement activities have been established to protect Florida panthers on several highways in the Big Cypress Preserve. The West Indian manatee receives considerable attention during the winter months. Endangered sea turtles receive special enforcement efforts during nesting season.

Accreditation: Should Wildlife Law Enforcement Participate? The concept of accreditation for law enforcement agencies became a reality in 1983 when the first agencies were accredited with the newly formed Commission on Accreditation for Law Enforcement Agencies, Inc. Accreditation provides a means for all law enforcement agencies, regardless of primary function, to document their commitment to the furtherance of professionalism in services provided to the public.

Conservation Education through a Cooperative Effort in Tennessee A cooperative agreement among the Tennessee Wildlife Resources Agency and 5 other organizations led to a unique conservation educational experience for visitors to the Unicoi County Heritage Museum (UCHM) in northeastern Tennessee. The adjacent grounds were designated a Wildlife Observation Area that provided an opportunity to view wildlife in natural situations. A quarter-mile nature trail and accompanying audiocassette guide were developed. A natural history exhibit featuring plants, animals, and geologic material was added to the museum.

Movements and Habitat Selection of Striped Bass in the Santee-Cooper Reservoirs Radiotelemetry which employed temperature-sensitive transmitters was used to monitor spring movement and summer habitat selection of 19 adult striped bass (Marone saxatilis) in the Santee-Cooper reservoirs, South Carolina. Nine fish were followed for 63 days during the late spring and summer 1985. Of the 61 recorded locations, 9 were fish which had utilized a thermal refuge. Mean water column temperature (28.1 0 C) and average thermal selection (27.80 C) did not differ significantly in observations where fish did not use thermal refuges. David W. Braschler, M. G.

Hybrid Striped Bass Movements and Habitat in Ross Barnett Reservoir, Mississippi Fourteen radio-tagged adult hybrid striped bass (female Morone saxatilis x male M. chrysops) were tracked from February to November 1987 in Ross Barnett Reservoir, Mississippi. Radio-tagged hybrids moved into the Pearl River in early March and remained upstream until water temperatures exceeded 27° C and dissolved oxygen decreased below 4 mg/liter at which time all except 2 fish returned to the main lake. These 2 fish, remaining in a well-aerated refuge at a lowhead dam, died in July when water temperatures exceeded 30° C. Paul S. Phalen, R. J.Muncy, T. K. Cross

Densities of fingerling striped bass (Marone saxatilis) resulting from natural reproduction in the Santee-Cooper Reservoir were estimated. Estimates during July and August of 3 years were 3.9, 4.0, and 7.8 fingerlings per hectare, which are much lower than typical reservoir stocking rates. Estimates were derived using a combination of the Petersen method and relative abundance.

Effect of Stocking Density on Production of Advanced Juvenile Hybrid Striped Bass Two nursery trials were conducted in 0.I-ha ponds to examine effects of density on production of juvenile reciprocal cross hybrid striped bass (female Marone chrysops x male M. saxatilis). In 1986, 1.4-g hybrids were stocked at 5,000, 10,000 and 20,000 fishlha. In 1987, 1.7-g hybrids were stocked at 12,500, 25,000, and 37,500 fishlha. During the studies, the fish were fed a commercial trout feed (38% protein) several times per day. Aeration and water exchange were provided to maintain satisfactory oxygen levels. After approximately 280 days, fish were harvested. Wallace E. Jenkins, T. I. J. Smith, A. D. Stokes, R. A. Smiley

Zooplankton Production and Pond Fertilization for Largemouth Bass Fingerling Production Inorganic fertilizers were tested in combination with organic fertilization to study enhancement of zooplankton communities in largemouth bass (Micropterus salmoides) rearing ponds in southeast Colorado. Under study conditions, additions of triple superphosphate produced the greatest number of zooplankton/liter, a combination of liquid ammonium nitrate and phosphoric acid produced the greatest growth, and the highest yields were found in ponds treated with phosphoric acid alone.

Macrobenthos in Fishponds with Different Alkalinities Macrobenthos was sampled during the summer of 1984 in a series of experimental fishponds with water alkalinity artificially adjusted to different levels (2.0, 3.8,6.9,8.4, and 35.8 mg/liter of CaC03 equivalents). Chironomid midges, nematodes, and tubificid oligochaetes accounted for 67% of all benthic organisms recovered. No significant trends were apparent as to abundance or type of benthic organisms encountered in each treatment. The most numerous midge in the samples was the detritivore/herbivore Einfeldia. The smaller predator midge Procladius was the second most abundant.

Gonadal Maturation, Fecundity, and Stripspawning of Female Spotted Seatrout Spotted seatrout (Cynoscion nebulosus) were collected from Matagorda Bay, Texas, from April 1984 through March 1986 and a gonosomatic index determined. Relative batch fecundity and ooycte maturation size were compared among females collected from April through October 1984, and randomly selected females were subjected to hormone-induced strip-spawning during June and July 1984. All females collected from April through August had yolked eggs and 4%-90% of fish collected in March, September, and October had yolked ova. No yolked ova were present in fish from November through February. Robert L. Colura, A. F. Maciorowski, A. Henderson-Arzapalo

Gear and Seasonal Biases Associated with Sampling Crappie in Oklahoma Differences in catch statistics (catch rates, length structure, and age structure) by gear and season were evaluated for white crappie (Pomoxis annularis) sampled with trap nets, electrofishing, and gill nets. Catch per man-hour of effort by trap nets was significantly higher than those of other gears tested in spring and fall. Variation in catch per man-hour was less for trapnet samples than for electrofishing or gillnet samples. Within-season variation in length distribution for trapnet samples was consistently less than within-season variation for the other gears tested.

Evaluation of Trapnetting for Sampling Black Crappie Trap nets were evaluated as sampling gear for black crappie (Pomoxis nigromaculatus) in 4,900-ha Lake Wylie, North Carolina and South Carolina. Compared with a creel survey, cove sampling with rotenone, and spring electrofishing, trap nets were the most efficient and cost-effective gear used for capturing black crappie at Lake Wylie. Age and size structure of black crappie captured in trap nets were similar to that harvested by anglers during the same season. Trap net catch rates (number per net set) also appeared to reflect densities of black crappie in Lake Wylie.

Growth History of Black Crappie Spawned 1980, St. Johns River, Florida Growth rates for the 1980 year class of black crappie were determined from samples collected in the St. Johns River, Florida, 1981 through 1987. Actual mean lengths of groups of black crappie aged by otolith evaluation were compared to back calculated lengths from otoliths of black crappie collected each year. Differences in actual and back calculated lengths for black crappie collected were not significant (P > 0.05). Coefficient of determination values (r2) dropped rapidly as differential growth rates increased. J. E. Crumpton, M. M. Hale, D. J. Renfro

Cold Tolerance in Two Subspecies of Bluegill Two bluegill subspecies (common bluegill Lepomis macrochirus macrochirus and coppernose bluegill L. m. purpurescens) were subjected to cold tolerance tests in the laboratory. Juvenile and adult bluegills were exposed to water temperature decreases of 1°C/hour from acclimation temperatures of 20° and 30° C until loss of equilibrium. Response temperatures of both subspecies were similar; temperatures at which 50% oftest fish lost equilibrium were usually <1.0° C lower for common bluegill and overlapping occurred in fiducial limits.

Spawning Season and Maturity of Blue Catfish in Kentucky Lake The spawning season and length at maturity were determined for female blue catfish in Kentucky Lake, Kentucky-Tennessee, where this species is commercially harvested. A gonosomatic index (GSI) was determined from 581 females of 3 length categories: 400-499 mm, 500-599 mm, 2:600 mm. The mean GSI for fish in the largest length category peaked at 3.72% during 1 May-15 May, when water temperature was 20.5° C, and rapidly dropped to 0.21% during 1 June-15 June. Spawning activity in 1986 peaked between 15 May and 15 June. Contributions to reproduction by fish <600 mm were clearly minimal.

Diet Composition of Stunted Catfish Populations in Louisiana Diet composition was investigated in 3 channel catfish (lctalurus punctatus) populations in southeastern Louisiana, 2 of which were characterized by slow growth and reduced length at maturity. Multivariate analyses revealed that diets of catfish exhibiting slow growth were predominantly composed of marine prey. particularly engraulids, Corophium sp., and Penaeus sp., and were superior in quantity, diversity, and apparent nutritional value compared to diets of faster growing catfish from the Atchafalaya Basin.

Flathead Catfish Abundance and Growth in the Flint River, Georgia Abundance and growth rates of flathead catfish (Pylodictis olivaris) from the Flint River, Georgia, were investigated during 1985 to gain basic information for future implementation of management strategies. Pectoral fins were disarticulated, sectioned at the articulating process, photographed, and enlarged for aging. The Schnabel and Schumacher-Eschmeyer multiple census population estimators produced similar results: there were 7,647 and 8,013 flathead catfish ≥ 305 rom in the 50-km section of river, respectively. Biomass estimates were 23.2 and 24.3 kglha.

Growth and Harvest of Catfish in Three Alabama Public Lakes White catfish (lctalurus catus) and channel catfish (I. punctatus) from 3 Alabama Public Fishing Lakes were sampled from 1979-1982 to obtain information on age and growth. Growth rates were found to be relatively uniform between the 2 species. Average first year growth of white and channel catfish was 118 mm and 127 mm, respectively. Creel data collected during a 1-year study period indicated that channel catfish dominated the catch. Seventy-nine percent of the catfish harvested at Chambers County Lake, 95% at Dallas County Lake, and 96% at Monroe County Lake were channel catfish.

Growth and Reproduction of Blueback Herring in a North Texas Reservoir The growth and reproductive cycle of a landlocked population of blueback herring (Alosa aestivalis) were evaluated in Lake Theo, a North Texas reservoir. Scales were collected and length, weight, and gonad characteristics were recorded for individual herring. Herring reproduced each year of the study. Average size of Age I herring ranged from approximately 70 to 170 mm total length (TL). Average size of Age II herring was approximately 200 mm TL and maximum size was 237 mm TL. Scale annuli formation in immature fish began in April; spawning marks occurred on scales in late summer.

Influence of River Discharge on Blueback Herring Abundance Adult and larval blueback herring (Alosa aestivalis) were sampled in the Santee River, South Carolina, during 1983 and 1984 under different discharge regimes. Discharge and water temperature were less variable in 1984, when at least 2 distinct peaks in abundance of adult herring were observed compared to 1 major peak in 1983. Adult and larval herring were more abundant in 1984 than 1983. The major contributor to larval abundance in 1984 appeared to be the later-occurring peak in adult herring abundance. Jeffrey C. West, A. G. Eversole, R. W. Christie

Effects of Gizzard Shad Introduction on a Small-impoundment Fishery Gizzard shad (Dorosoma cepedianum) were introduced into an 83-ha public fishing lake in central Missouri in an attempt to improve populations of high density, slow growing largemouth bass (Micropterus salmoides), white crappie (Pomoxis annularis), and bluegill (Lepomis macrochirus). A 380-mm length limit on largemouth bass was introduced at the same time. Growth rates of both bass and crappie increased. William M. Anderson, C. F. Rabeni

Possible Competitive Effects of Two Introduced Planktivores on White Crappie Field and laboratory experiments were conducted to investigate possible competitive effects of the introduced species inland silversides (Menidia audens) and threadfin shad (Dorosoma petenense) on the native white crappie (Pomoxis annularis) population in Thunderbird Reservoir, Oklahoma. Field collections of zooplankton and stomach analyses were augmented by laboratory feeding experiments with the introduced planktivores and white crappie, alone and in combination. Field samples indicated that silversides, shad, and crappie, showed positive selectivity (Strauss' L) for Daphnia.

Characteristics of Urban Anglers in Lubbock, Texas Angler surveys were conducted at 18 lakes in municipal parks during JuneDecember 1987. Anglers < 16 years old were the largest proportion of the participants. Of the anglers surveyed, 93% were residents of Lubbock. They averaged 6.9 fishing trips per month and fishing frequency differed among age groups and between summer and fall. Resident anglers travelled an average of 4.7 km to fish; distance travelled differed among age groups and between summer and fall. Anglers preferred to catch catfish (Ictalurus spp., 79% of anglers) and largemouth bass (Micropterus salmoides, 72%). Harold L. Schramm, Jr., J. A. Dennis

Largemouth Bass Population Changes Following Implementation of a Slot Length Limit Following 3 years of a 356 mm (14 inch) minimum length limit on black bass, a protective length range (slot) regulation was placed on Arbuckle Reservoir, Oklahoma. This slot length limit protected both largemouth and spotted bass in the 300-381 mm (12-15 inch) range. Bass density, as indicated by spring electrofishing catch-per-effort (C/f, increased over the duration of the study. Most noteworthy was the increase in density of largemouth bass>381 mm long. Proportional Stocking Density (PSD) also improved as an indication of changes in population structure.

Characteristics of the Freshwater Drum Fishery below Jordan Dam Freshwater drum (Aplodinotus grunniens) are a significant component of the fishery resource in the Jordan Dam tailwater (Coosa River, Ala.). Most of the exploitation of the freshwater drum is centered around a spring influx into the system which appeared to be primarily mature fish moving upstream to spawn. There was little evidence of reproduction by this species within the tailwater. Although condition factors were highly variable across the range of lengths sampled, growth rates for freshwater drum in the Jordan Dam tailwater exceeded those reported elsewhere in the United States.

Attended and Unattended Yo-yo Fishing Catch and Mortality Yo-yo catch and mortality of caught fish were evaluated at Caddo Lake, Texas, using attended (checked at least once each hour) and unattended fishing techniques. A total of 400 yo-yos (200 attended and 200 unattended) were fished 3,991.75 hours during February and March. Ten species were caught; black crappie (Pomoxis nigromaculatus) and yellow bullhead (Ictalurus natalis) comprised 54% and 20% of the catch, respectively. Catch rates were significantly higher for attended sets (0.12 fish/yo-yo hour) than unattended sets (0.03 fish/yo-yo hour). Timothy W. Schlagenhaft, M. A. Webb

Comparison of Gill Nets and Jug Lines for Selectively Harvesting Large Gar The effectiveness of gill nets and jug lines were evaluated for selectively harvesting large alligator gar (Lepisosteus spatula) and longnose gar (L. osseus) in Sam Rayburn Reservoir, Texas. Gill nets with bar-mesh sizes ranging from 5.08 to 15.24 cm and jug lines were fished during September and October 1986. Catch per unit of effort (CPUE) in number of fish per man-hour, lengths of gar captured, and relative selectivity by gear were compared. Average effort required to fish I gill net or 10 jug lines overnight was 1 man-hour. Edgar P. Seidensticker, R. A. Ott, Jr.

Fish Community Structure and Zonation Related to Stream Habitat Twenty-seven quantitative fish collections and site habitat analyses were performed from October 1985 to April 1988 in the Little Missouri River in Southwest Arkansas. Longitudinal addition of fish species (from 9 to 30) corresponded to downstream change in physical habitat. Species diversity increased from headwaters to midreaches and was positively correlated with increasing stream size, decreasing particle substrate size, depth, and development of alluvial riffle/pool morphology.

Growth and Food Habits of Saugeye (Walleye x Sauger Hybrids) in Thunderbird Reservoir, Oklahoma Saugeye (Stizostedion vitreum vitreum X S. canadense) stocked in Thunderbird Reservoir from 1985-1987 were monitored for growth, food habits, and possible diet overlap with largemouth bass (Micropterus salmoides) as they progressed from age-1. Age-1 and age-2 saugeye attained mean length of 445 mm and 543 mm, respectively, by October. Food habits revealed saugeye 301-400 mm began converting from inland silversides (Menidia beryllina) to shad (Dorosma spp.) as their main food item. A predator-prey length relationship showed mean prey length was approximately 30% of predators.

Walleye Spawning, Movements, and Habitat Usage in Tombigbee River Drainages A total of 13 radio-tagged walleyes (Stizostedion vitreum vitreum) were monitored from spring through summer in 1986 and 1987 in Luxapalila Creek near Columbus, Mississippi. Movements indicated pre-spawning aggregation in the lower Luxapalila Creek during January and February, upstream spawning March through early April, and widely varying downstream post-spawning movements. Seasonally high water discharges in March were cues for upstream movements to pool areas below spawning sites at shallow <1.5 m) gravel riffles. High discharges restricted spawning and possibly reproductive success.

Sample Size Requirements for Detecting Length Differences of White Shrimp Subsampling to obtain length measurements is often necessary when large numbers of organisms are captured with bag seines in a resource monitoring program. Catches of white shrimp were used to examine the representativeness of the subsamples and to construct sample size selection curves for determining the number of length measurements required to detect a given percentage difference between samples. A wide size range of white shrimp (Penaeus setiferus) is often captured in the same sample. Jeff F. Doerzbacher, S. R. Marwitz

Social Organization Among White-tailed Deer During Rut Visual observations on group composition of white-tailed deer (Odocoileus virginianus) on the Fred T. Stimpson Wildlife Sanctuary, Alabama, were conducted from November 1975 through March 1976. Group composition was divided into 3 periods (pre-rut, 6 Nov - 6 Jan; rut, 7 Jan - 29 Feb; post-rut, March) to determine effects of reproductive behavior. During the study, 937 groups containing 2,391 deer were sighted. Sightings of single males and single females increased during the rut, and mean group size decreased.

Evaluation of Alligator Hatchling and Egg Removal from Three Florida Lakes The removal of 50% annual alligator production over a 6-year period on 3 central Florida lakes did not appreciably change population size structures. On Lake Jessup, increases were found in the >0.6 m size classes, while on Lake Griffin no changes were found in any size classes. Lake Apopka experienced significant (P <0.05) declines in all size classes, but these declines resulted from unexplained and unrelated mortality and reproductive failures and not from the early age-class harvest. No change in size structure was found for the control area, Lake Woodruff. Michael L. Jennings, H. F. Percival, A. R. Woodward

Seasonal Food Habits of Black Bears in Great Dismal Swamp, Virginia-North Carolina Food habits were determined for a black bear (Ursus americanus) population in Great Dismal Swamp on the Atlantic Coastal Plain. A total of 535 scats was collected from May 1984 to August 1986. Seasonal shifts in diet composition were similar to previously reported findings for black bear food habits in the southeastern United States. Diets changed from succulent, herbaceous material in the spring to soft mast and corn in the summer. Early fall diets were largely black gum (Nyssa sylvatica) (33%) and oak (Quercus spp.) (32%) mast.

Evidence for and Consequences of Deer Harvest Data Biases Harvest data constitute an important source of information for the deer manager, but interpretation can be complicated by reporting bias, hunter selectivity, differential vulnerability, and aging errors. Daily harvest records for >165,000 white-tailed deer (Odocoileus virginianus) taken during 1979-85 Illinois firearm seasons were examined for evidence of bias. Antlered males were apparently killed at a higher rate than other classes of deer; consequently, they became relatively less numerous in the herd and in the harvest as the season advanced.

A Survey of Parasites and Diseases of Pen-raised Wild Turkeys Evaluations of health status were made on 119 pen-raised wild turkeys (Meleagris gallopavo) by complete necropsy, serological, and microbiological testing, blood smear examinations, subinoculation trials, and parasite identification. At least 33 species of parasites including 9 protozoans, 14 helminths, and 10 arthropods were found. Infectious disease agents isolated or identified histopathologically were avian pox virus, Mycoplasma gallisepticum. and Aspergillusjumigatus. Serologic testing disclosed antibodies to infectious bursal disease virus-2, M. gallisepticum. M. meleagridis. L. F. Schorr, W. R. Davidson, V. F. Nettles, J. E. Kennamer, P. Villegas, H. W. Yoder

Recovery and Economics of Pen-reared Bobwhites in North-central Texas A total of2,l89 pen-reared northern bobwhites (Colinus virginianus) was banded and released when 14 weeks old on a hunting club in north-central Texas from May 1984 through February 1985. Recovery of banded birds released during the 5 months preceding the hunting season was 7.5%, whereas 38.6% of birds released during the first 3 months of the hunting season were recovered compared to 55.4% of those released during the last 2 months. Release of birds just prior to the hunt decreased the cost per bird recovered to $6.5 as compared to $18.65 for birds released 14 days before the hunt.
