Effects of stocking density and water exchange rate on growth and survival of channel catfish Ictalurus punctatus (Rafinesque) in circular tanks

Channel catfish were cultured for 177 days in circular tanks containing 1.6 m3 of water at combinations of five stocking densities (90–720 fish/m3) and five water exchange rates (2.0–0.5 h per exchange). Net yield increased as stocking density increased up to 540 fish/m3 then declined at higher densities. Mean fish weight, feed conversion efficiency and survival all declined as stocking density in

Bald eagles (Haliaeetus leucocephalus) found dead or moribund in the United States and Canada and submitted to Patuxent Wildlife Research Center were examined for helminth parasites. Nine genera of helminths were reported which include new host records for Clinostomum complanatum, Neogogatea pandionis, Centrorhynchus sp., Serratospiculum amaculata, Capillaria contorta, and Habronema americanum.
