Fish meal and alternate sources of protein in fish feeds: Update 1993 Fish meal and alternate sources of protein in fish feeds: Update 1993

Close to 12% of the world's 6.5 million metric tons of fish meal is used for aquaculture feeds. If current trends continue, roughly 20% to 25% of total world fish meal production could be used for aquaculture by the year 2000. Fish stocks used in fish meal reduction, however, appear to be in worldwide decline. A growing fish farming industry and a stagnating, if not diminishing, supply...

Eye abnormalities of lake trout exposed to gas supersaturation Eye abnormalities of lake trout exposed to gas supersaturation

Lake trout (Salvelinus namaycush) reared for 1 year at six levels of differential (excess) gas pressure (▵P 4, 17, 33, 43, 58, and 75 mm Hg above equilibrium) were examined for incidences of eye abnormalities including nuclear cataracts, hemorrhages, corneal swelling, cloudiness, rupture, and loss of eyes. Frequencies of nuclear cataracts, eye hemorrhages, cloudy corneas, and bilateral...

Comparison of plasmids isolated from Romet-30-resistant Edwardsiella ictaluri and tribrissen-resistant Escherichia coli Comparison of plasmids isolated from Romet-30-resistant Edwardsiella ictaluri and tribrissen-resistant Escherichia coli

Edwardsiella ictaluri, the etiological agent of enteric septicemia of channel catfish (ESC) is the leading cause of bacterial disease in commercially raised channel catfish Ictalurus punctatus. The only drug approved by U.S. Food and Drug Administration for use against ESC is Romet-30. Recently, several isolates were obtained that had a naturally occurring resistance to Romet-30. On...

Assimilation efficiency for sediment-sorbed benzo(a)pyrene by Diporeia spp. Assimilation efficiency for sediment-sorbed benzo(a)pyrene by Diporeia spp.

Two methods are currently available for determining contaminant assimilation efficiencies (AE) from ingested material in benthic invertebrates. These methods were compared using the Great Lakes amphipod Diporeia spp. and [14C]benzo(a)pyrene (BaP) sorbed to Florissant sediment ( 63 µm). The first approach, the direct measurement method, uses total organic carbon as a tracer and yielded AE...
