The use of mixed algae is best for sea
cucumber larvae however, the best feed
combination and appropriate feeding levels
have to be looked into. Auricularia larvae
can be fed a mixture of different algae such
as Chaetoceros muelleri, C. calcitrans,
Isochrysis galbana, Nannochloropsis sp.,
and the temperate alga Phaeodactylum
tricornotum. P. tricornotum is cultured
at low temperature of 19-24oC in the
laboratory with artificial lights (Fig. 12).
The sea water medium is 1-μm mesh
filtered and UV treated, and enriched with
chemical fertilizers at the rate of 2 to 3 ml
per l of water. Chaetoceros, Isochrysis
and Nannochloropsis are all cultured in
the laboratory or in outdoor tanks (wat
