TL;DR: Dietary uptake and biological effects of decabromodiphenyl ether in the rainbow trout (Oncorhynchus mykiss) are studied.

TL;DR: The reproductive disorders observed indicates disturbed endocrine function(s), arresting the majority of the female perch in a sexually nonreproducible immature stage, the first to report evidence for endocrine disruption in wild populations of fish living in a lake exposed to leakage water from a public refuse dump.

TL;DR: In this paper, the authors demonstrate strong relationships between idiopathic paralytic disease, breeding failure, and thiamine deficiency in eggs, pulli, and full-grown individuals.

TL;DR: The problem of thiamine deficiency is considerably more widespread and severe than previously reported and linked to secondary effects on growth, condition, liver size, blood chemistry and composition, histopathology, swimming behaviour and endurance, parasite infestation, and reproduction.

TL;DR: An assumed aquatic pollution gradient was confirmed, with the city of Stockholm as a point source of anthropogenic substances, with poor health status of the perch: retarded growth, increased frequency of sexually immature females, low gonadosomatic index, and disturbed visceral fat metabolism.
