A preliminary study on the effects of dietary supplementation of brewers yeast and nucleotides, singularly or in combination, on juvenile red drum (Sciaenops ocellatus)

Aquaculture Research (2005)

Peng Li Gary S. Burr Jonathan B. Goff Kasey W. Whiteman Kenneth B. Davis

This study was designed to evaluate the effects of dietary supplementation with brewers yeast (Brewtech®) and nucleotides (Optimûn), either singularly or in combination, on red drum growth, body composition, stress responses and possible resistance to Amyloodinium ocellatum infection. Juvenile red drum (∼1 g initially) fed practical fish-meal-based diets for 6 weeks had similar weight gain regardless of whether the diet was unsupplemented (basal) or supplemented with brewers yeast (2% of diet), nucleotides (Optimûn at 0.2% of diet) or both brewers yeast (2% of diet) and nucleotides (Optimûn at 0.2% of diet). Dietary effects on hepatosomatic index, intraperitoneal fat ratio or whole-body composition were not significant, except that fish fed the singular nucleotide supplement had a significantly higher whole-body lipid content compared with fish fed the basal diet. No significant dietary effects on cortisol response were observed after a 15 min confinement stress test perhaps because of the extreme variation among individual fish. Subsequently, in situ challenge by co-habitation with A. ocellatum caused 100% mortality regardless of dietary treatment within a 48 h period. It is concluded that dietary supplementation of brewers yeast and nucleotides did not promote enhanced growth or improved cortisol response and resistance to uncontrolled amyloodiniosis in juvenile red drum, at least at the tested dosages.

Effect of Simulated Copper Sulfate Therapy on Stress Indicators in Channel Catfish

Journal of Aquatic Animal Health (1999)

Billy R. Griffin Kenneth B. Davis Daniel Schlenk

Plasma cortisol concentrations in juvenile channel catfish Ictalurus punctatus exposed to 1.7 mg copper sulfate/L for 24 h in a simulated therapeutic treatment episode rose to a level significantly greater than unexposed fish and declined when the exposure was discontinued. Plasma glucose concentrations were elevated immediately and increased during exposure to twice the level in control fish. The maximum glucose concentration was followed by a slow decline to the preexposure level by 54 h after discontinuing exposure. Plasma lactate concentrations did not change until after the exposure period, but by 30 h there was a significant increase. Plasma chloride levels were significantly reduced during exposure and remained so before returning to preexposure levels by 54 h after exposure. No changes were observed in hematocrit values, hepatic metallothionein protein, or in plasma-associated aspartate aminotransferase, alanine aminotransferase, and lactic dehydrogenase, suggesting that little cellular damage accompanied the simulated treatment episode. Our results indicate that therapeutic doses of copper sulfate, although acutely stressful, cause a mild degree of stress in channel catfish compared with other stressors.

Isozyme Expression and Gene–Centromere Distances in Diploid and Triploid Hybrid Catfish

Transactions of the American Fisheries Society (1996)

Qinghua Liu Cheryl A. Goudie Bill A. Simco Kenneth B. Davis Donald C. Morizot

Allozyme expression of 14 loci was studied in diploid channel catfish Ictalurus punctatus, blue catfish I. furcatus, and diploid and triploid hybrid catfish (channel catfish × blue catfish). This allowed appropriate interpretation of allozyme expression and estimates of gene–centromere distances in triploid hybrid catfish and contributed to genetic characterization of the commercially important ictalurid catfishes. Five polymorphic loci in the parental female channel catfish were used to confirm the retention of an extra diagnostic maternal allele in triploid offspring. Fidelity of gene dosage and allozyme expression of three parental alleles were found at 13 of 14 loci of triploid progeny; however, expression of phosphoglucomutase (PGM) in 174 and 197 triploid hybrids was similar to that of diploid hybrids. Electrophoretic variation for PGM was observed when different buffers were used, indicating nongenetic alteration of expression. Two polymorphic loci in triploid hybrid catfish provided new gene–centromere distances of 14 centimorgans (cM) for aspartate aminotransferase (mAAT*) and 45 cM for glucose-6-phosphate isomerase (GPI-A*). No differences were found in recombination rates of isocitrate dehydrogenase (IDHP*) and peptidase-5 (PEPS-1*) loci of triploid hybrids at different ages.

Feminization of Channel Catfish by Oral Administration of Steroid Sex Hormones

Transactions of the American Fisheries Society (1983)

Cheryl A. Goudie Barry D. Redner Bill A. Simco Kenneth B. Davis

Oral administration of 17-β-estradiol or 17-α-ethynyltestosterone to sexually undifferentiated channel catfish Ictaturus punctatus during the first 21 days after yolk-sac absorption resulted in the production of 100% females. The androgen was effective at doses of 6 to 600 μg/g of feed, but not at 0.6 μg/g. Received February 5, 1983 Accepted June 12, 1983

A Technique for Sexing Channel Catfish

Transactions of the American Fisheries Society (1976)

Virginia M. Norton Kenneth B. Davis H. Nishimura

A simple, accurate technique has been devised to sex externally channel catfish, Ictalurus punctatus, regardless of body size or state of gonadal maturation. Male catfish have a single urogenital opening; females have two openings partitioned by a septum—an anterior genital pore, and a posterior urinary pore. In male fish, a single probe can be inserted into the urinary bladder through the urogenital pore. Female fish are differentiated from males by the insertion of two probes, one into the urinary bladder through the urinary pore and the second into the oviduct through the genital pore.

Plasma Corticosteroid Stress Response of Fourteen Species of Warmwater Fish to Transportation

Transactions of the American Fisheries Society (1986)

Kenneth B. Davis Nick C. Parker

Plasma corticosteroid concentrations were measured in 14 species of fish immediately after they were electrofished from reservoirs on the Alabama River and after they had been transported for 2 h. There was no corticosteroid response in spotted gars Lepisosteus oculatus. Bowfins Amia calva, longnose gars Lepisosteus osseus, and freshwater drums Aplodinotus grunniens had only small corticosteroid increases (14–39 ng/mL) during transportation. Corticosteroids increased by intermediate amounts (59–184 ng/mL) during transportation in blue catfish Ictalurus furcatus, paddlefish Polyodon spathula, largemouth bass Micropterus salmoides, channel catfish Ictalurus punctatus, river carpsuckers Carpiodes carpio, white bass Morone chrysops, striped bass Morone saxatilis, and crappies Pomoxis sp. The greatest increases were 223 ng/mL in gizzard shad Dorosoma cepedianum and 286 ng/mL in common carp Cyprinus carpio. Spotted and longnose gars, largemouth bass, and common carp also were held in tanks for about 2 months at 21°C and then stressed by confinement in a dip net for 30 min. The confinement caused significant increases (P < 0.01) of plasma corticosteroid concentration in all four species. Dip-net confinement appears to be a useful method for comparing corticosteroid responses among species of warmwater fish.
