Acute Toxicity of Six Forest Insecticides to Three Aquatic Invertebrates and Four Fishes by Herman O. Sanders,Mack T. Finley,Joseph B. Hunn Pdf

Technical grade and field formulations of six experimental forest insecticides -- methomyl, carbaryl, aminocarb, trichlorfon, fenitrothion, and acephate -- were tested for acut toxicity against three species of aquatic invertebrates, (a daphnid, an amphipod, and larvae of a midge), and four species of fish (bluegill, rainbow trout, fathead minnow, channel catfish). Five of the six insecticides were highly toxic or extremely toxic to the daphnid, amphipod, and midge larvae. The sixth insecticide, acephate, was not toxic to invertebrates at concentrations up to 50 mg/L. Five of the insecticides ranged from highly toxic (methomyl to channel catfish) to relatively non-toxic (trichlorfon to fathead minnows); the sixth, acephate, was only slightly toxic to the fishes tested.

Forage Fishes in Marine Ecosystems by Alaska Sea Grant College Program Pdf

Forage fishes are of particular concern in Alaska because lack of these prey fishes is most likely the cause of a dramatic decline in Steller sea lions, fur seals, and seabirds in the past 20 years. This book, the proceedings of the 1996 International Symposium on the Role of Forage Fishes in Marine Ecosystems, is organized around several themes: Fish biology, their role as predators and prey, causes of population fluctuations, assessment methods, and management. Fifty-six research contributions are included. Selected as an outstanding publication by the Journal of Government Communication.
