Missouri's Approach to Stream Resource Management

Despite continued deterioration and outright destruction of many streams Missourians still have a notable and diverse stream resource. Nearly 9,900 miles of permanent streams and 8,200 miles of intermittent streams with permanent pools remain. Positive stream management practices and activities in Missouri include water quality surveillance and control, access site acquisistion and development, stocking for put-and-take trout fishing, National Scenic Riverways designation, commercial fishing on some larger rivers, and continuing research projects.

Reservoir Management Prognosis: Migraines or Miracles

There are about 500 reservoirs (larger than 500 acres), totaling 4.3 million acres, in the 14 States of the Southern Division. Angling demand is predicted to double on Southern waters by the year 2000, and most of the increase is expected to be satisfied by man-made lakes. Southern reservoirs are typically below average in basic fertility, but long growing seasons foster high annual production rates, resulting in above average sport fish yield potentials.

Problems and Solutions, Goals and Objectives of Fishery Management

This summary and discussion covers four papers on current fishery management problems and programs in small ponds and community lakes, reservoirs, streams, and coastal and estuarine environments. Problems are classified in four major categories: economic, political, social, and biological. Biological problems are subdivided as either environmental (physical-chemical) or biotic. In discussing the goals and objectives of fishery management, a distinction is made between the terms harvest, catch and yield, and the goals of maximum sustained harvest and optimum sustained yield.

Effect of Rate of Water Discharge on Phytoplankton in Claytor Lake, Virginia

Claytor Lake, Virginia, an 1820 ha main stem hydroelectric reservoir, was studied for one year to determine the effect of water discharge on reservoir phytoplankton. Number/liter, areal units/liter, average cell size, and chlorophyll a content were used as measures of photoplankton abundance. Rate of water discharge had an adverse effect on reservoir phytoplankton during spring and summer.

The Effect of Increased Sodium Chloride on Striped Bass Fry Survival in Freshwater Ponds

An investigation of the effects of increased sodium chloride concentrations on striped bass fry survival was conducted at the Auburn University Fisheries Research Unit from April 8 to July 7, 1972. The mean survival of fry in ponds with increased sodium chloride concentrations was 7.65% as opposed to 1.70% in six control ponds. The survival in all ponds was highly variable, ranging from 0.33 to 39.50% in increased sodium chloride ponds and from 0.00 to 9.58% in control ponds.

Aroclor@ 1254 in Eggs of Sheepshead Minnows: Effect on Fertilization Success and Survival of Embryos and Fry

The effect of the polychlorinated biphenyl (PCB), Aroclor 1254, in eggs of the sheepshead minnow, Cyprinodon variegatus, on fertilization success and survival of embryos and fry was investigated. Adult fish were exposed for four weeks to 0.1,0.32, 1.0,3.2 or 10.0 ug/l of PCB, then injected twice with 50 lU of human chorionic gonadotrophin to stimulate egg production. The eggs were fertilized, placed in PCB-free flowing seawater and observed for mortality. Fertilization success was unimpaired by concentrations in eggs as high as 201 ug/g but survival of embryos and fry was reduced.

Preliminary Studies on the Tolerance of the White Amur, Ctenopharyngodon idella, to Rotenone and Other Commonly Used Pond Treatment Chemicals

The White Amur, Ctenopharyngodon idella, was found to be able to withstand recommended pond treatment concentrations of potassium permanganate, formalin, copper sulfate, and malachite green. In all instances, 100% of the test fish survived a 96 hour tolerance period at concentrations above the dosages recommended and used by the Arkansas Game and Fish Commission for disease and vegetation control in earthen ponds. Both rotenone and antimycin were bio-assayed for possible use as a toxicant selective toward the White Amur.

Comparatlve Tolerance of Fingerling Black Crappie, White Crappie, and Largemouth Bass to Fintrol-5 at Two Ph Levels

A comparison of tolerance of fingerling black crappie, white crappie and largemouth bass to Fintrol-5 was conducted in aquaria. White crappie were found to be more susceptible to Fintrol-5 than were black crappie and largemouth bass. Largemouth bass and black crappie showed similar tolerance to the toxicant. The mortality of largemouth bass and black crappie was significantly reduced at a pH of 8.0-8.5. All three species suffered significant mortalities beginning with .04 ppm Fintrol-5 at a pH of 7.0. One ppm KMn04 significantly reduced mortality by detoxifying Fintrol-5.

Response of Intensively Fed Channel Catfish to Diets Containing Various Protein - Energy Ratios

Six experimental catfish feeds, containing 29, 36, and 42% crude protein at metabolizable energy (ME) levels of 1000 and 1300 kcal per Ib, were fed to fingerling channel catfish in 24, 1/ I0-acre earthen ponds for 165 days. Each dietary treatment was randomly assigned to four ponds which were stocked at a rate of 4,000 fish per acre. Feed allowance was increased biweekly on the basis of fish weight gain until a maximum daily allowance of 40 Ib per acre was reached.

A Preliminary Evaluanon of a Fish Diet Based on Roasted Soybeans and Fresh Fish

Two experimental fish diets, one consisting of50% roasted soybeans and 50% fresh fish, and another consisting of 30% soybeans, 20% corn meal, and 50% fresh fish, both with vitamin and mineral supplements, were compared to Oregon pellets in a 6 week feeding trial using yearling channel catfish (lctalurus punctatus). The experimental diets were ground, blended and pelletized by passing the ingredients through a food chopper four times. Both mixtures proved highly attractive to the fish. Fish fed either experimental diet grew as well as fish fed the Orgon pellets.

Oxidation Pond Algae as a Supplement for Commercial Catfish Feed

Investigations have shown that small (less than 10 cm) channel catfish fingerlings, Ictulurus punctatus Rafinesque, gained as much weight in a 10 week period on a diet of 25%-75% oxidation pond algae-commercial feed as did control animals fed 100% commercial feed. Larger fish (20-25 cm) fed the algal-supplemented diet did not gain as much weight in 10 weeks as did control fish on 100% commercial feed. Whole body protein and fat levels did not differ significantly between control and experimental fish.

Effects of Chinese Waterchestnut in Floating Rafts on Production of Channel Catfish in Plastic Pools

Chinese waterchestnut was grown in rafts floating on catfish pools to determine effects on production of channel catfish fed daily. This plant may remove nutrients from the water and increase catfish production by improving water quality and, also, produce a second crop, the edible corm ofthe plant. Catfish were stocked in March, Chinese waterchestnuts were planted in April, and both were harvested in October.

Evaluation of Recirculating Systems for the Culture of Channel Catfish

Channel catfish can be cultured at high densities in carefully managed recirculating raceway systems. Various flow rates, exchange rates, and tank to filter ratios were investigated in ten recirculating systems employing biological filters, settling chambers and foam strippers. Limestone, shells, styrofoam and teflon rings served as effective filter media, but coal slag restricted water flow and was not satisfactory. An equation was developed to evaluate the effects of system design on water quality.

Growing Channel Catfish, Ictalurus Punctatus (Rafinesque), in Raceways

Techniques were investigated for growing channel catfish, lctalurus punctatus (Rafinesque), from fingerlings to harvestable size fish during the summer months in a recirculation, flowing water fish culture system in South Georgia. When stocked at a density of 2,000 fingerlings per 100 ft raceway unit, mean production was more than 2,400 Ib per unit with a feed conversion ratio of 1.28 to 1. Survival of the fish was 98.1 %. Successful culture of 2,400 fish in one unit indicated that the carrying capacity of the raceways used in this study was greater than 2,000 fish.

Influence of Floating and Sinking Feeds and Fingerling Size on Channel Catfish Productions

A comparison was made with a floating and sinking ration of similar analysis produced by the same manufacturer. This study demonstrated an increase in catfish production when using the sinking ration. Moreover, the sinking feed produced fish of a larger average size, a better food conversion, and a smaller Ktl factor. Use of sinking feed represented a savings of approximately $54 to $72 per acre on the feed bill. Data were compared for the influence of fingerlings size at stocking (4.5, 6.5 and 8 inch) upon catfish production.

Homing Behavior of Flathead Catfish, Pylodictis Olivaris (Rafinesque), Tagged with Ultrasonic Transmitters

Homing behavior of flathead catfish in an Oklahoma reservoir was observed by tracking fish bearing a 74 kHz transmitter which had been implanted in the peritoneal cavity. Homing is described from 1,190 fixes (site locations) obtained on 22 flathead catfish. The average tracking interval was 18.7 days. Homing occurred in 8 of 12 (67%) fish displaced a distance of 1.3-2.7 km from the site of capture. Average accuracy of homing fish was within 182m of the original site of capture. One transmitter tagged fish, displaced 1.82 km, returned to the site of capture within 1.7 days.

An Evaluation of Catchable Trout Movement Using Two Marking Techniques

Two marking techniques, freeze branding and subcutaneous tags, were used to evaluate movement of catchable rainbow trout (Salmo gairdneri) stocked into Rich Creek, West Virginia. These marks proved to be a valuable tool in studies requiring both rapid recognition of marked fish and identification of individuals. In general, there was a marked movement of trout downstream from the point of release, even during periods of low water conditions. Mean distances moved in both directions were 465 meters downstream and 197 meters upstream, respectively.

Seasonal Variation in Food and Diel Periodicity in Feeding of Northern Largemouth Bass, Micropterus S. Salmoides (Lacepede), in an Oklahoma Reservoir

Food habits of 810 northern largemouth bass, 91-2724 g total weight (age groups 0-7) were determined from collections made June 1968 through November 1969 in an 808-hectare, Oklahoma reservoir. Bass were colIected by traversing the shoreline with an electrofishing apparatus and bass stomach contents observed with a gastroscope. Fifty-five percent of all bass stomachs were empty. Similar observations over a wide geographic area were reviewed and the suggestion was made that 56% occurrence of empty stomachs may be used as a guide to evaluate availability of forage for largemouth bass.

Studies on Scale Structure of Flatfishes I. The Genus Trinectes, with Notes on Related Forms

A detailed comparison of the scales of Trinectes maculatus (Bloch and Schneider) and T. inscriptus (Gosse) has demonstrated species specific differences valid for taxonomic purposes. A complex hinged joint attaching very large cteni to the scale plate characterizes both species. The large cteni are associated with a marked increase in skin surface which, in turn, is combined with an apparent increase in the cutaneous vascular bed suggesting a secondary respiratory and excretory function.

Food Habits of White Amur, Largemouth Bass, Bluegill, and Redear Sunfish Receiving Supplemental Feed

White amur effectively controlled dense growths of Mougeotia, Zygnema, and Eleocharis, when introduced into a pond containing a supplementally fed largemouth bass-bluegill-redear population. Analysis of stomach contents showed that white amur preferred plant foods (88% by volume), and probably ingested a few insects and crustaceans while "grazing" on plant materials. Largemouth bass preferred fish and other animals (64%), but also ate some supplemental feed (32%).

Description and Evaluation of a Portable Drop-Net for Sampling Nekton Populations

An improved design of a portable drop-net is presented. The drop-net was used to sample estuarine nekton populations whose densities were later determined by the DeLury regression method. The drop-net samples provided mean density estimates that were 4-33% of the DeLury estimate for pelagic fishes, 50-100% for semi-demersal and demersal fishes, and 82-100% for macrocrustaceans (crabs and shrimp). The degree of variation between drop-net samples depended on the species, with the greatest variation seen in samples of pelagic fishes.

Sampling Shallow Water Fish Populations Using the Wegener Ring

The Wegener Ring was designed to sample fish populations of shallow, vegetated habitats in Lake Tohopekaliga, Florida. The sampler is portable and simple to use. Ten transects in water 0-18 inches deep were sampled within consecutive 3 inch contours. As depth of water increased, non-centrarchid forage fish decreased while numbers of centrarchids increased. Total numbers of fish decreased from an average of 216,042 per acre in 0-3 inches to 20,326 per acre in 15-18 inches of water. Standing crop was relatively constant, averaging 91 pounds per acre for all water depths.

A Comparison of Fish Faunas in a Highly Stressed and a Less Stressed Tropical Bay - Guayanilla and Jobos Bay, Puerto Rico

Jobos and Guayanilla Bays are semi-enclosed bays on the south coast of Puerto Rico. J obos Bay receives some small amounts of raw sewage from two small villages and some wastes from a sugar central. Guayanilla Bay receives some sewage from a town on one shore, hydrocarbon, heavy metals, and carbohydrate addition from a petrochemical complex, and heat from an electrical power generating plant. Species diversity as indicated by the Shannon- Weaver index is higher in Jobos but the lowest values found in either bay are higher than these reported for normal temperate aquatic systems.

Farm Fish Production in Arkansas During 1972

Fish farming in Arkansas continues to be a major industry with 1972 returns exceeding $21 million. This indicates an overall increase in value of23.5 percent since 1969. Acreage of intensively-farmed waters increased 15.7 percent since 1969. Data collected during this survey indicates that a peak in the industry was reached between 1969 and 1972 and that during the past year acreages devoted to fish production declined slightly. Personal interviews of fish farmers provided the most useful data in determining the total production.

Growth of White Crappie and Channel Catfish in Relanon to Varianons in Mean Annual Water Level of Lake Carl Blackwell, Oklahoma

Variations in annual increments of growth of white crappie. Pomoxis annularis Rafinesque, and channel catlish, Ictalurus punctatus (Rafinesque), are examined in relation to mean annual water level of Lake Carl Blackwell, 1962-1967, when lake level was declining. The occurrence of lee's phenomenon precluded a correlative comparison of white crappie growth with water level, but decrease in growth at age I and the increase at older ages is attributed to the decline in water level.
