Book Description
Feeding trials using fall chinook salmon finglerlings were conducted at the Salmon Cultural Laboratory, Longview, Washington, during 1971 for the purpose of improving the Abernathy diet formula. The results indicated that cottonseed meal could replace a portion of the fish meal in the diet without reducing fish growth, but similar substitutions of wheat and corn gluten meal reduced growth. Fish growth was significantly increased when a diet containing 50 percent protein and 3,350 kcal per kilogram was fed as compared with a diet containing 45 percent protein and 3,350 kcal per kilogram. Soybean lecithin proved to be equal to soybean oil as a caloric source when fed at 2 percent of the diet. Two types of dried whey product with different levels of lactose content produced similar growth response. Reducing the dried whey portion of the diet to 5 percent did not affect growth, nor did methionine supplementation produce any effects. Anchovy meal was unsuitable as a replacement for herring meal.

Nifurpirinol (NFP), also know by code name P-7138, was tested for control of furunculosis, myxobacterioses, and vibriosis, and for effects on rainbow trout, coho, and chinook salmon under various conditions. Further tests are needed to verify the use of NFP for control of other bacterial diseases.

Book Description
Acute and long-term (20-day) toxicities of 40 insecticides to four species of freshwater malacostracan crustaceans (the scud, crayfish, glass shrimp, and aquatic sowbug) were determined in static and intermittent-flow bioassays. An extremely wide range in toxicity was found with scuds generally being the most sensitive, followed in descending order by glass shrimp, sowbugs, and crayfish.

Book Description
Morphological, physiological, and serological studies on 55 myxobacteria isolated principally from gill disease, tail rot, and other myxobacterial infections showed that a variety of myxobacteria occur in these infections. Athought there were different morphological types of myxobacteria, all strains from freshwater and estuarine sources were physiologically similar. Isolates from marine sources were physiologically less active than the other test organisms.
