The effect of DHA/EPA ratio in live feed on the fatty acid composition, survival, growth and pigmentation of turbot larvae Scophthalmus maximus L.
A set of experiments was designed to understand the effect of standardized enrichment diets on the fatty acid composition and culture performance of turbot larvae reared using the food chain rotifers -freshly hatched Artemia nauplii- enriched Artemia . Rotifers were fed on experimental diets of simi...
