Feeding experiments of rotifers enriched with different levels of n-3HUFA (highly unsaturated fatty acid) by two kinds of commercial algae (Marine Glos and Marine Alpha) on larval brown sole (Pleuronectes herzensteini) for the purpose of improving the survival, growth and starvation resistance were conducted using 200L and 5L rearing tanks for 27days. Suitable concentration of n-3HUFA was estimated more than 433.1-590.1mg/100g on a dry matter basis for the survival, growth and starved resistance of larvae. Especially feeding of rotifers enriched both DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) was more effective to the survival of larvae than that only enriched with DHA. Ability of starvation resistance of larvae was apparently raised with feeding rotifers enriched by DHA rather than EPA.
