In marine fish breeding, the larval stages of many fishes are critical due to their small
mouth gape and changes in feeding habit. Microalgae are unicellular phytoplankton
which have less than 10 μ size. Among the different live feeds micro algae Nanocloropsis
occulata, Chlorella salina, C. marina, Isochrysis galbana, Tetraselmis chuii,
Pavlova lutheri, Skeletonema costatum, Thalassiosira sp., Chaetoceros gracilis,
C.calcitrans,, and micro zooplanktons (nauplii of the brine shrimp Artemia spp.), the
rotifer Brachionus plicatilis, B. rotundiformis, calanoids and copepods, cladoceran
crustaceans (Daphnia spp. and Moina spp.), etc. together plays an important role in
larval production system. Rotifers isolated can be cultured in 25 to 30 ppt water using
micro algae or yeast as feed and mass scale production can be done using yeast and
rice bran. Artemia nauplii are being produced through decapsulation of artemia cysts
and the nauplii thus obtained can be harvested and cultured in seawater using micro
algae as feed. It is recommended that adequate nutrition has an important role in the
reproductive success of all animals including fish and it has been shown that essential
fatty acids, vitamin (A,E and C), trace minerals and b-and other carotenoids can affect
fecundity, egg quality, hatchability and larval quality.
