Malignant lymphoma in black bullhead from Allouez Bay, Superior, Wisconsin, USA Malignant lymphoma in black bullhead from Allouez Bay, Superior, Wisconsin, USA
Leukemic malignant lymphoma was diagnosed in a black bullhead collected from Allouez Bay, in an industrialized Lake Superior estuary near Superior, Wisconsin, USA. No gross signs of thymic involvement were observed and it is believed this tumor originated in the hematopoetic tissue of the kidney. Neoplastic cells infiltrated excretory kidney, spleen, liver and gill tissue. This finding...

Increases in gill cytosolic corticosteroid receptor abundance and saltwater tolerance in juvenile coho salmon (Oncorhynchus kisutch) treated with growth hormone and placental lactogen Increases in gill cytosolic corticosteroid receptor abundance and saltwater tolerance in juvenile coho salmon (Oncorhynchus kisutch) treated with growth hormone and placental lactogen
Juvenile coho salmon (Oncorhynchus kisutch) were injected with one of two recombinant bovine hormones, growth hormone (bGH; 5.0 and 0.5 μg · g-1 body wt) or placental lactogen (bPL; 5.0, 0.5, μg · g-1 body wt) to determine the effect on growth, plasma cortisol concentration, cytosolic corticosteroid receptors (CR) in the gills, and the development of hypoosmoregulatory ability. One week...

Partial replacement of fish meal with spray-dried blood powder to reduce phosphorus concentrations in diets for juvenile rainbow trout, Oncorhynchus mykiss (Walbaum) Partial replacement of fish meal with spray-dried blood powder to reduce phosphorus concentrations in diets for juvenile rainbow trout, Oncorhynchus mykiss (Walbaum)
Feeds formulated with 5.7, 11.4 and 22.7% spray-dried blood powder, also called blood flour (88.1% protein, 0.2% total phosphorus), were compared with a control diet with 49% herring meal (64% protein, 2.1% total phosphorus) and no blood powder for rearing juvenile rainbow trout. Oncorhynchus my kiss (Walbaum). Diets with 5.7, 11.4 and 22.7% blood powder contained 1.22,1.03 and 0.84%...

Influence of fish oils in production catfish feeds on selected disease resistance factors Influence of fish oils in production catfish feeds on selected disease resistance factors
Healthy channel calfish, Ictalurus punctatus (mean weight: 62.5g), were fed two production feeds that were identical except for the lipid portion, which was either catfish oil or menhaden oil. Fish were held at 18 or 28°C and fed the experimental feeds for four monlhs. A subsample of fish from each of the four treatments was then used to measure scrum antibody titers to Edwardsiella...

Effect of seasonally changing feeding habits on whole-animal mercury concentrations in Hydropsyche morosa (Trichoptera: Hydropsychidae) Effect of seasonally changing feeding habits on whole-animal mercury concentrations in Hydropsyche morosa (Trichoptera: Hydropsychidae)
Food habits, net-spinning activity, and whole-animal mercury concentrations in Hydropsyche morosa Hagan were examined monthly over a one year period on the South River, Virginia. Gut content analysis revealed seasonal patterns in the consumption of food that was correlated with net-spinning activity. Between April and October, when feeding nets were widespread, detritus represented...
