Evaluation of Walleye Fingerling Plants in Lake Darling, North Dakota
… instigated experimental stockings of walleye fingerlings in the years 1952, 1953, and 1954 with special emphasis on distribution methods, planting procedures, and condition of the fish. This study is an attempt to evaluate these experimental stockings. Information on age and growth along with …

Evaluation of a Power Plant Reservoir as a Fingerling Walleye Rearing Facility
… in 1986 and 1987 as a potential rearing site for fingerling walleyes (Stizostedion vitreum vitreum). Percent of stocked fish harvested was 0.21% (1,874 fish) in 1986 and 0.02% (129 fish) in 1987. Harvest was low because winterkill did not eliminate fish predators from the evaporation pond. …

The use of selected enzyme activities as indices of growth and nitrogen metabolism in fingerling channel catfish (Ictalurus punctatus)
… 3 were short-term (7-week) growth trials with fingerling catfish in aquaria under controlled laboratory conditions. Parameters measured each week included instantaneous daily gain of the fish (IDG) and the activities of selected enzymes - glutamate dehydrogenase (GDH), aspartate …

The impacts of stocking stress and largemouth bass predation on the survivorship of juvenile striped bass stocked in Smith Mountain Lake, Virginia
… shown an inverse relationship between number of fingerling striped bass stocked and survival to age 1. Potential causes for this inverse relationship include largemouth bass predation on fingerling striped bass and mortality resulting from stocking stress. Cage studies performed in 1994 and 1995 …

Reproductive Manipulation and Larval Rearing Techniques of Yellow Perch (Perca flavescens)
… four separate spawns annually, yielding 644,000 fingerlings year-1. Including start-up, fixed and variable costs, such a facility can produce 3" (76mm) fingerlings for $0.20 fingerling-1 for the first 5 years of operation, $0.16 fingerling-1 for the second 5 years and $0.06 fingerling-1 after 10 …

Benthic invertebrate management in plastic-lined fish culture ponds
… for the benthic food base as well as growth of fingerling walleye. In 2003, effects of supplemental fish food on fingerling growth and survival, as well as the benthic invertebrate community were investigated. It was found that supplemental feed did not significantly increase the benthic …

Relative Survival and Growth of Walleye and Saugeye Fingerlings Stocked in South Dakota Small Impoundments
… walleye x sauger Stizostedion canadense hybrids) fingerlings were concurrently stocked at equal densities into five small impoundments in 1997 and 1998 to evaluate relative survival and growth. Prior to stocking, fish were differentially marked with 7 0 0 ppm oxytetracycline hydrochloride (OTC) to …

Early life history dynamics of a stocked striped bass (Morone saxatilis) population and assessment of strategies for improving stocking success in Smith Mountain Lake, Virginia
The early life history dynamics of stocked, fingerling striped bass (Morone saxatilis) were evaluated in Smith Mountain Lake, Virginia, from 1994-96 and incorporated into an individual-based model to assess various stocking strategies in terms of their largest percent increases in first-year …

The effects of acute handling stress on the secondary stress responses of striped bass (Morone saxtilis) and its hybrid (Morone chrysops x Morone saxtilis)
… in a dipnet. The first study was conducted with fingerling inland and anadromous striped bass. The three goals were to: determine if fingerlings responded with the General Adaptation Syndrome, if the two had different responses to the stress, and if feeding state (fed up until the day of the …

Trophic Level Changes and Alewife Predation on Conesus Lake
… with yearly stockings of 65,000 3-5 cm walleye fingerlings. While these fingerling plantings were not successful, nevertheless alewife in Conesus Lake declined by 41% from 1985 to 1988. A likely cause for this decline is a decrease in the alewife's forage base. In 1988, this study was initiated …

Use of High Pressure Liquid Chromatography to Detect and Quantify Oxytetracycline Marks in Walleye Otoliths and Dorsal Spines
… in walleye Stizostedion vitreum fry and fingerlings. Current visual methods for detection of these marks are subjective, and biologists are unable to quantify the amount of OTC in a sample. The goal of this study was to determine if high pressure liquid chromatography (HPLC) is a feasible …

The Effects of Glochidiosis on Fish Respiration
… reducing the surface area for gas exchange. Fingerling bass (̃5 g) were infected with 0-1006 glochidia per fish. In normoxic water, resting ventilation rates were elevated in proportion to the number of attached glochidia and up to 2X controls. The rate of oxygen consumption (MO2) and …

Food Habits, Growth, and Production of Young-of-the-Year Walleyes, Stizostedion vitreum vitreum (Mitchell), in a South Dakota Pond
… Stizostedion vitreum vitreum (Mitichell), fingerling on 13 June, 1973. Walleyes were monitored for growth rate and food habits until 13 September, 1973. Walleyes were removed from the pond using various methods in order to evaluate the efficiency of removal methods. The average total length …

Comparative Ecology of Juvenile Striped Bass and Juvenile Hybrid Striped Bass in Claytor Lake, Virginia
… sampling season. Predation upon stocked fingerlings was not considered significant in limiting juvenile survival; only three fingerling moronids were found in the examination of stomach contents of 200 potential predators captured near stocking sites. It does not appear that resource …

Factors Affecting Recruitment of Black Crappies in South Dakota Waters
… an overabundant black crappie population. Small fingerling (circa 3-4 cm) stockings in 1992 and 1993 had relatively low survival; fall electrofishing CPUE values for age-0 saugeyes were 5/h and 3/h. In 1994 and 1995, larger (circa 14-19 cm) fingerlings were stocked, and fall CPUE values were …

Natural Reproductive Cycle of Northern Largemouth Bass in the Upper Midwest, with Applications to Off-season Spawning
… northern largemouth bass M. s. salmoides fingerlings are produced for stocking purposes at Blue Dog State Hatchery using traditional pond culture methods. Fingerlings (~75 mm) are harvested and transported to stocking sites during late summer. Fingerling survival to age-1, however, is …

Competition Between Age-0 Largemouth Bass And Juvenile Bluegills In A Virginia Pond
… may explain why enhancement stocking of fingerling largemouth bass typically is not successful. Further research is needed on the appropriate timing and length at stocking of introductory largemouth bass stockings. Additionally, I recommend that resource partitioning and competition …
