Choline-betaine requirements of rainbow trout (Oncorhynchus mykiss)
A series of experiments with rainbow trout (Oncorhynchus mykiss) were conducted to quantify the dietary requirement for choline as well as to determine whether betaine or methionine could spare the trout's choline requirement. Fish weighing 1.4 and 3.2 g, which were acclimated to a choline-deficient semipurified diet for 14 days before the start of the experiments, were shown to have a choline req

Whirling disease: Earliest susceptible age of rainbow trout to the triactinomyxid of Myxobolus cerebralis
Various developmental stages of eyed eggs and newly hatched sac fry of rainbow trout (Oncorhynchus mykiss) were exposed to several concentrations of laboratory produced spores of the triactinomyxon stage of Myxobolus cerebralis, the infective stage of salmonid whirling disease. Exposed eggs and sac fry and appropriate unexposed controls were examined microscopically immediately after challenge for

Survival and growth of larval striped bass (Morone saxatilis) fed Artemia enriched with highly unsaturated fatty acids (HUFA)
The nutritional value of Artemia nauplii from the Great Salt Lake was effectively improved for larval striped bass (Morone saxatilis) by incorporation of unsaturated fatty acids (20: 5n-3 and 22: 6n-3) into the nauplii by the direct method of enrichment. Survival at 24 days post-hatch increased from 23% to 64% when fish were fed nauplii containing 8.24% lipid as 20: 5n-3 and 3.10% as 22: 6n-3 fatt

Genotypic and phenotypic variability of Zostera marina on the west coast of North America
The relation between environmental factors and leaf morphology of Zostera marina L. have long been unclear, primarily because the species is intrinsically variable. The common-garden method was used to determine the genetic, environmental, and interaction components of leaf size variation. Zostera marina consists of several ecotypes with a wide range of phenotypic plasticity. Variation in the morp

Resistance of underyearling and yearling Atlantic salmon and lake trout to supersaturation with air
Juvenile Atlantic salmon Salmo salar and lake trout Salvelinus namaycush of different sizes were exposed for 96 h to water supersaturated with air. Underyearlings (Atlantic salmon shorter than 66 ± 8 mm [mean total length ± SD] and lake trout shorter than 96 mm) were resistant to high dissolved-gas pressures. The level of supersaturation causing 50% mortality was lower for yearling Atlantic salmon
