- Abstract:
- ... Anadromous salmonids are viewed as a prized commodity and cultural symbol throughout the Pacific coast of North America. Unfortunately, several native salmonid populations are threatened or at risk of extinction. Despite this, little is known about the behavior and survival of these fish as the juveniles transition from freshwater to the ocean. Our primary objectives were to estimate survival of j ...

- Abstract:
- ... An 8‐wk feeding trial was conducted to investigate the effects of dietary n‐3 highly unsaturated fatty acids (n‐3 HUFA) on growth, body composition, and fatty acid profiles of juvenile Acanthopagrus schlegeli. Three replicate groups of fish (initial mean weight: 8.08 ± 0.09 g, mean ± SD) were fed diets with different levels of n‐3 HUFA (0.76%, HUFA₀ .₇₆; 0.83%, HUFA₀ .₈₃; 0.90%, HUFA₀ .₉₀; 0.97%, ...

- Abstract:
- ... This cross-sectional study examined various aspects of cubicle design and management in terms of their potential as risk factors for hock lesions, using an epidemiological approach. Cubicle dairy farms in Germany and Austria with Holstein Friesian or Simmental cows were visited during the winter housing season. 105 farms and 3691 cows were included in the analysis which consisted of three steps: b ...

- Abstract:
- ... We compared performance (growth, survival, and condition) of northern largemouth bass Micropterus salmoides salmoides fingerlings fed one of three commercial starter feeds: Otohime Marine Weaning (OMW; Marubeni Nisshin Feed), Bio-Oregon BiVita Fry (BVF; Bio-Oregon), and Purina Aquamax Starter (PAS; PMI Nutrition International LLC). Nine 833-L circular tanks, connected in parallel to a recirculatio ...
