TL;DR: Computer assisted sperm analysis is shown for the first time to provide a rapid and quantitative measure of the effects of environmental pollutants on the quality of fish sperm, suggesting concentrations of cadmium which have been found to be present in fish gonads as a result of bioaccumulation from the water or diet may decrease the motility of sperm during maturation or storage in the testis.

TL;DR: The most sensitive sperm : ova ratio for monitoring pollutant effects on fertilization success was 1500 : 1, which corresponds to half the minimal amount that yields a high fertilization rate in artificial insemination.

TL;DR: It is demonstrated that jade perch are able to produce both n-3 HU FA and n-6 HUFA when dietary PUFA are present, and that feeding the Schizochytrium diet for a continuous period of 14 weeks lowered overall sensory property scores.

TL;DR: The bioactivity of the GH preparation was demonstrated by the short-term effect of GH on T3 plasma levels in juvenile catfish, and data unequivocally confirm the identity of the purified molecule as suggested by immunochemical evidence.

TL;DR: To determine the replacement of fish oil with vegetable oils in the diet of juvenile Jade perch Scortum barcoo, four feeds with each a different oil (fish, sunflower, linseed and a mixture of 75% canola and 25% linseed oil), were fed to Jade perich reared in recirculating aquaculture systems (RAS).
