Meta-analysis of density-dependent somatic growth
Density-dependent somatic growth may have a number of significant impacts on fish populations. First, it may be an indirect compensatory mechanism if abundance affects growth negatively and adult body size determines egg or larval survival.... 2009-10-05

Influence of vitamin E in reproduction in rainbow trout (Salmo gairdneri)
The effects of the withdrawal of vitamin E from the diet of maturing rainbow trout were assessed in the female, in the developing eggs, and in the resultant offspring. Groups of 6 pretreated female rainbow trout (initial weight 598 g) were either... 2009-10-05
