Description To standardize the hatchery feed protocol for larval rearing of Paphia
malbarica, the present study emphasized on optimum algal feed requirement
of larvae at all stages of development. As the algal feed fulfills, the
physiological and biological needs during development, the suitable micro
algal production in a hatchery system could be benefited for the larval rearing
and spat production on a commercial basis.
In most bivalve hatcheries, the phytoflagellate Isochrysis galbana was
used as feed in early larval stages, without considering the optimum
requirement of this species. The present study revealed that a cell
concentration of 5 x 103 cells/ml is the ideal density for larval rearing of P.
malabarica.
The present work, with an objective, to evaluate the efficiency of other
micro algae such as Nannochloropsis salina, Tetraselmis gracilis, Dicrateria
inomata, Chaetoceros calcitrans and Dunaliella salina as an alternative feed
to I. Galbana. Among these micro algae, it is established that
Nannochloropsis salina could be used for larval rearing and spat production,
since it showed good result in terms of early settlement (day 9 -11), survival
(83 %) and high growth rate (15 f,lm/day) when fed as single diet.
