Laboratory Spawning And Larval Rearing Of Red Drum And Southern Flounder Laboratory spawning and larval rearing studies were conducted with red drum (Scianenops ocellata) and southern flounder (Paralichthys lethostigma) from 1974 through 1977. Adult fish were placed in 29.92 kl spawning tanks equipped with biological filters and subjected to photoperiods and temperatures regulated to simulate seasonal variations. Red drum spawned 52 times producing 6.0 X 107 eggs. Southern flounder spawned 13 times producing 1.2 X 105 eggs. Eggs were collected and incubated, and larvae were reared to fingerling size. C. R. Arnold, William H. Bailey, Theodore D. Williams, Allyn Johnson, James L. Lasswell

Effects Of Masoten (Dylox) On Plankton In Earthen Ponds The effects of Masoten, an organophosphate parasiticide, on phytoplankton and zooplankton in earthen ponds were studied. In 2 separate trials, 3 ponds (0.04 hal received a single application of Masoten at a rate of 0.25 mg/l (active ingredient) and 3 ponds served as untreated controls. Net plankton samples were collected at pretreatment, and 5, 24 and 48 hI's following treatment. Toxic effects were based on quantitative.qualitative plankton analyses. Phytoplankton and rotifers were unaffected by treatment. The copepod Diaptomus sp. and nauplii were also unaffected. Joseph P. McCraren, Travis R. Phillips

Effects Of A Pumped Storage Hydroelectric Plant On Reservoir Trout Habitat Jocassee Reservoir (3,063 ha) is the upper pool for a 61O·MW pumped storage hydroelectric plant in northwestern South Carolina. Trout (200-225 mm long) have been stocked annually since 1972. The volume of trout habitat during summer has decreased annually from 1973 to 1976, and is associated with increases in the temperature and volume of water pumped from the lower reservoir. The top of the thermocline during September was lowered from about 9 m in 1973 to nearly 19 m in 1976, and trout habitat was reduced by about 65%. James L. Oliver, Patrick L. Hudson, James P. Clugston

Effect Of Temperature On Walleye Egg Hatch Rate This study was conducted to determine if water temperature increases during the walleye (Stizostedion vitreum vitreum) spawning period reduced egg hatch rate and if water temperature manipulation during egg fertilization would increase hatch rate. Walleye eggs were subjected, before and during fertilization, to 1 of 3 treatments involving water temperatures above and below 12 C. Water temperatures above 12 C were found to reduce hatch rates. Stripping and fertilizing eggs collected from reservoir water temperatures above 12 C into water chilled to 7.2 C significantly increased hatch rates. John A. Prentice, Wilfred J. Dean, Jr.

Reproductive Repression Of Largemouth Bass In A Heated Reservoir This study investigated possible factors inhibiting spawning of largemouth bass (Micropterus salmoides) in Victor Braunig Lake, a 547 ha power plant cooling reservoir in Bexar County, TX. Data on water quality, fish communities, pesticide and heavy metal concentrations and largemouth bass blood components and sexual development were analyzed from Braunig Lake and Calaveras Lake, a similar power plant lake nearby. All factors were similar between the 2 lakes. Largemouth bass from Braunig Lake began spawning 2 days after being moved to hatchery ponds. Wilfred J. Dean, William H. Bailey

Preliminary Observations Of Fish Attraction To Artificial Midwater Structures In Freshwater Midwater artificial structures were placed in a freshwater reservioir to determine if fish would associate with these structures. SCUBA observations were used to evaluate the effectiveness of the structures. Alabama spotted bass (Micropterus punctulatus henshalli) and bluegill sunfish (Lepomis macrochirus) were attracted to structures suspended over water depths up to 33 m and as far as 250 m from the shoreline. Behavioral observations of fish on structures and the development and subsequent association of spotted bass fry spawned on a structure are discussed. William C. Reeves, Gerald R. Hooper, Barry W.

Spotted seatrout (Cynoscion nebulosus) and red drum (Sciaenops ocellata) populations in Texas bays were randomly sampled with 183 m long gill nets November 1975 through March 1976 and November 19'76 through March 1977. Catch rates in areas closed to commercial netting for spotted seatrout were about twice as high as those from areas open to netting. There was no difference between the mean total length of spotted scatrout from closed areas and trout from open areas. Closed areas produced about twice as many red drum as open areas. Gary C. Matlock, James E. Weaver, Albert W. Green Pages 477-483 |

An Intensive Culture System For Channel Catfish Fingerlings Channel catfish (Ictalurus punctatus) were stocked at rates of 250, 500, 1,000 and 2,000 fry /208 1 drum, and reared to fingerling size. No significant differences occurred in rate of gain from days 0-33, but gains ranged from 0.22 g/day at the 250 stocking rate to 0.08 g/day at the 2,000 stocking rate from days 0-70. The highest average total biomass of 10,095 g was reached at the 2,000 stocking rate. Flow rate was maintained at a constant 0.32 I/sec in all drums. Food conversion from days 17-70 ranged from 1.42 at the 250 stocking rate to 2.67 at the 2,000 stocking rate.

Effects Of Bass Stocking And Rates Of Fishing On A Largemouth Bass Population Supplemental stocking of fingerling and intermediate size largemouth bass (Mieropterus salmoides) did not provide substantial control of forage fish populations; however, stocking fingerling bass may have improved year class strength in those years they were stocked. Although loss of stocked intermediate-size bass over the spillway was negligible, those fish were vulnerable to angling. A measured rate of fishing (F = 0.08) was exerted on a population of bass estimated at 22.3 harvestable bass/ha weighing 34 kg/ha. Curtis S. Lawson, William D. Davies

Estuarine Fishery Dynamics And Freshwater Inflow Fluctuations In The San Antonio Bay Systems, Texas The quantity, quality, and timing of freshwater inflows to the San Antonio bay system are recognized as major factors in fishery production. A methodology has been developed using commercial fishery statistics and gaged inflow records to analyze the fishery dynamics and its relation to freshwater inflows from the contributing river basins. Statistical correlation analysis and assessment of "best" versus "worst" years of production were employed to evaluate the effects of year to year fluctuations in freshwater inflows.

Tailwater Fisheries Of Lake Of The Ozarks And Pomme De Terre Lake, Missouri The tailwater fisheries of Lake of the Ozarks and Pomme de Terre Lake were measured by a part-time roving creel survey from 1965 through 1974. Catch rates of fishes were compared with temperature, conductivity and dissolved oxygen, but no significant correlations were found. However, high positive correlations existed at Lake of the Ozarks tailwater between annual average catch rates and the annual average discharge of water, and also between preceding mean monthly discharges and following monthly catch rates.

Stocking Density: Its Effect On Caged-Channel Catfish Production Channel catfish (Ictalurus punctatus), were reared in 1.0 m' cages suspended in the intake canal of a cooling reservoir. Effects of density were tested by stocking cages in replicates of 4 at densities ranging from 500 to 900 fish in increments of 25 individuals. There was a significant increase in net production and variation in length and a signifi· cant decrease in feed efficiency, mean fish weight, and percentage of harvestable-size fish as stocking density increased. Survival was not affected by number of fish per cage. Carlos H. Pennington, Kirk Strawn

Penaeid Shrimp Abundance And Riverine Flow In San Antonio Bay, Texas The relationships of abundance of brown shrimp (Penaeus azteeus Ives) and white shrimp (P. setiferus L.) to spring and fall river flow into San Antonio Bay, Texas were studied. Standing crop indices determined from trawl sampling and bay commercial landings were poorly correlated; only those indices obtained from trawl samples were deemed valid. Brown shrimp abundance showed no detectable relationship to changes in freshwater inflow; white shrimp abundance, however, showed a significant positive correlation with May-June inflow and with the previous year's September-October inflow.

Length at maturity computed for female flathead catfish (Pylodietus olivaris) from marshes of southwest Louisiana was 589 mm. Empirical data showed males approach maturity in the 390-439 mm size range. The length-weight regression for flathead catfish was best described by: Log W = -8.9640 + 3.3732 Log L, where W = weight in kg and L = length in mm, r = 0.97. The computed total length-collarbone length conversion equation for flathead catfish was Y = 10.3428 + 0.7251, where Y = total collarbone length in mm and X = total body length in mm, r = 0.99. W.

Migration Of Sauger Past A Thermal Discharge In Melton Hill Reservoir A total of 259 sauger (Stizostedion canadense) was tagged and released downstream of Bull Run Steam Plant during the winters of 1974-75 and 1976. Gill nets and electrofishing gear were used to recapture sauger that moved into the discharge basin or past the plant. Over the study period 7 sauger were recaptured upstream from the discharge; 3 of these had moved past the plant while it was continuously operating. Fourteen sauger were caught in the discharge. The thermal plume from Bull Run Steam Plant had no significant effect on the movement of sauger. R. W. Schneider, W. K. Wilson, B. L. Evenhuis

Characteristics Of Sport Fishing Activity In Three Warm Water Discharges Creel surveys were conducted at TVA's Gallatin, Kingston, and John Sevier Steam Plant discharge basins from March 1975 through May 1976. The highest period of angler use at all plants occurred between April and June. Peak harvest and pressure in the 3 discharge basins were significantly related, and high periods usually occurred later in the year than has been reported from other areas. At least 18 species were found in the combined creel from the 3 plants, and species diversity was greatest during the warm months. R. W. Schneider, A. O. Smith, V. P. Mitchel, Jr.

An Analysis Of Fish Associations In Tennessee And Cumberland Drainage Impoundments Distribution of fish in the heavily impounded Tennessee and Cumberland River systems shows definite longitudinal zonation similar to that in nonimpounded river systems. Ten of 11 physical variables examined were highly correlated with one another, reflecting the complex of conditions accompanying changes from storage reservoirs in upper elevations to mainstream reservoirs in the lowlands. Elevation was the variable most highly correlated with the number of species. Thomas A. McDonough, William C. Barr

Evaluation Of The Trout Fishery In The Tailwater Of Bull Shoals Reservoir, Arkansas, 1971-73 The fishery for rainbow trout (Salmo gairdneri) in the Bull Shoals tailwater has developed as a seasonal boat fishery which in peak years provides more than 250,000 angler days of fishing, and a catch of more than 750,000 trout. Use was concentrated along the upstream one-third (48 km) of the tailwater in 1971-73, where about 60 percent ot the total fisherman effort, 50 percent of the catch, and 75 peroent of the total guided fishing occurred.

Algae-Fed Brine Shrimp Nauplii As A Food Source For Larval Spotted Seatrout Larval spotted seatrout (Cymoscion nebulosus) grew faster on 1 and 2 day prefed brine shrimp (Artemia salina) nauplii than fish fed newly-hatched nauplii. Fish growth and survival were reduced when 3 and 4 day pref.ed, as compared with newlyhatched nauplii were offered. Proximate analysis and calorimetry demonstrated the occurrence of a temporal decline in the nutritional value of both fed and unfed brine shrimp nauplii. Robert B. McGeachin, Robert R.

A Comparison Of The Diets Of Redbreast Sunfish And Spotted Sucker In A Coastal Plain Stream The diets of r,edbreast sunfish (Lepomis auritus) and spotted sucker (Minytrema melanops) in the Satilla River, Georgia, were shown to be quantitatively different using Spearman rank correlation coefficients. The index of overlap of Pianka by number and weight showed considerable overlap in the diet during the fall. Chironomids were the main food component contributing to this overlap. The index of electivity of Ivlev indicated moderate to high selectivity by both species for chironomids in the winter, spring, and summer and some selectivity in the fall. Charles E. Coomer, Jr., Daniel R. Holder, Clayton D. Swanson

Effects Of The Steroid, Methandrostenolone, On Growth And Gross Pathology Of Channel Catfish Methandrostenolone was not effective in promoting growth in channel catfish (Ictalurus punctatus) at the 2.5 mg/kg of body weight/day dosage level. There were no significant differences (.05 level) in treated and untreated fish with respect to total weight gain, percent crude protein, and moisture content of the Hesh. No differences were observed in gross morphology, liver to body weight ratios, or microscopic examination of liver sections. Kenneth R. Perry, J. Larry Wilson

Seasonal Fish Population Fluctuations In South Florida Swamp We monitored fish populations in a southwest Florida cypress (Taxodium distichum) strand system through an annual wet season-dry season cycle. Populations increased from zero when the site was inundated to densities of 3-8 fish m2 and biomass of .3-.4 g/m2 in late wet season. Two months after drydown began, fish became concentrated. In wet prairie and "pond" cypress habitats concentration continued until the sites went dry, but "bald" cypress populations reached high densities early, then stabilized until just prior to complete drydown, when they decreased drastically.

Heat Tolerance Of Free-Living Estuarine Animals To Predict Their Survival In Heated Effluents Individual heat resistance times were determined in 180 min experiments during June 1974 through September 1975 for 8 species of crustaceans and 47 fishes taken directly from the intake canal of the P. H. Robinson Generating Station, Bacliff, Texas. Indi· vidual r,esistance times increased with an increase in capture temperature and with a decrease in test temperature. June-September is the most thermally critical period of the year for animals transported by the power plant from intake water and exposed to hot discharge effluent.

Ultrasonic Tracking Of Smallmouth Bass In Center Hill Reservoir, Tennessee Ultrasonic tracking was conducted on 11 smallmouth bass (Micropterus dolomieui Lacepede) in Center Hill Reservoir, TN from 24 May 1973 to 25 July 1974. Transmitters which had an average life of 30.4 days, were implanted in the body cavity and were a successful tool for studying fish movement and behavior. Factors observed were "homing" behavior of displaced fish, horizontal movement, distance ranged offshore, depth ranges, water temperature, and habitat preference. Anders I. Myhr, III, Douglas C.

Hunting And Trapping Furbearers In Texas: A Personal Experience Through many years of participation, I have found that hunting and trapping furbearers offers some of the finest sport in the field of outdoor recreation. It can be enjoyed by almost any interested person. The resulting rewards are an invigorated spirit, mind and body and, at times, a handsome economic supplement. Consequently, all efforts should be directed to refine the taking offurbearers in the most ethical manner in order to enhance and perpetuate the fascinating sport.

The increasing need for a "specialized" Wildlife Officer to insure compliance with the multitude of complex State and Federal laws governing the exhibition, importation, exportation, propagation, and sale of wildlife and fresh water fish has prompted the Florida Game and Fresh Water Fish Commission to establish the Wildlife Inspections Section. The regulation of these activities continues to pose obstacles to most state conservation agencies; therefore, this paper will identify Florida's methodology toward resolution of these issues through personnel and program specialization.

Salt Water Shrimp Law Enforcement: Its Evolution In Texas The purpose of this paper is to show the results and the impact of the Texas Shrimp Conservation Act and the enforcement of shrimp laws in Texas. Enacted in 1959, it provides for open and closed seasons, sizes of shrimp, trawl and door sizes, licenses needed, and for the patrol and enforcement of the Act. It provides that all salt waters in Texas, wherever shrimp were found, would be patrolled both by aircraft and boat.

Dynamic Deployment Of Wildlife Law Enforcement Manpower - A Decision Aid A methodology for deciding how to deploy law enforcement personnel is proposed. A workload model is used. The methodology is consistent with the concept of management by objectives (MBO) and could serve as a focal point for achieving improved effectiveness in an enforcement division. Use of this model may require the creation of a statewide information system describing the geographical distribution of wildlife agent workload. Cleveland J. Cowles, Robert H. Giles, Jr., Kirk H.

Fines In Wildlife Law Enforcement MQnetary fines have been routinely assessed wildlife law violators for almost 2 centuries in the United States. Due to the humanizing of statutory law, sanctions for wildlife law violations have progressed from mutilation and deportation to monetary fines and short-term confinement. Misdemeanor case material compiled in recent years suggests that sanctions may have some deterrent effectwhen the certainty ofimposition is reasonably high. Kirk H. Beattie, Robert H.

The Approaching Crisis in the Registration of Fishery Chemicals Review of the status of chemicals used in fisheries indicates that many lack proper registrations. Regulations of the U.S. Environmental Protection Agency and U.S. Food and Drug Administration require that all existing registrations be reviewed and reregistered by October 1977. Adequate data to support reregistration are lacking for some of the most widely used chemicals. Applications of unregistered compounds are strictly prohibited under penalty oflaw. Cancellation of existing registrations.
