Comparative value of live and frozen marine (Chlorella) for sea bream (Sparus aurata) larviculture with the pseudo green water technique.

Summary

The value of frozen marine Chlorella was compared to that of live in two steps of the pseudo green water technique used for sea bream larviculture: for realisation of the rearing medium by daily addition to the larval rearing tank; and for the enrichment of the rotifers Brachionus plicatilis, performed prior to utilisation as prey. The experiments lasted 20 days and were performed in 2 types of tanks: experimental and pilot-scale ones. The addition of frozen phytoplankton to the rearing medium did not affect the growth of the seabream larvae, but its use for enrichment of the rotifers was responsible for larval mortalities 15 days after hatching in the pilot scale trial. These mortalities could be avoided when lipidic commercial emulsion was also used for the rotifer enrichment. The results were discussed.
