Abstract

One of the principal problems in marine fish larval rearing which includes financial loss is related to increased mortality in the stage while larvae have to shift feeding on formulated from live food. The reasons for applying weaning are high production costs, increased bacterial load and unreliable nutritional value of live foods. The commercial dry feeds can address this concern and decrease the larval production costs and consequently generate a highly profitable investment. In this paper, it was tried to consider recommendation which helps the aquaculturists to pass this larval stage successfully. Attention to the larval development stage, larval behavior, feeding strategies and considering the factors such as effective health management and monitoring the environmental conditions which affect the success of this change are met to discuss.
