Abstract:
The main objective of the present work is to acquire information
regarding the growth responses of P. monodon larvae (from PZ1 upto PL1)
to various mono specific and mixed diets. Evaluate the nutritional quality of
selected species of micro algae viz. Chaetoceros calcitrans, Dunaliella
salina, Isochrysis galbana and Nannochloropsis salina, larvae at three cell concentrations 10x104 cells/ml, 25x104 cells/ml and
50x104 cells/ml.
The P. monodon larvae were transported, at the Nauplius stage, to the
laboratory. The larvae were stocked at density of 150 larvae per litre in 5 litre
FRP tanks with 3 litres of sea water. The algal cell density given to the larvae
varied. The larval stages were fed with increasing densities of algae to
evaluate the relationship between the food densities, ingestion rates,
development and growth of the larvae. The water quality parameters, the
percentage of survival rate, the growth estimation and the algal cell count
were done. Each experiment was carried out in triplicate with a control group
of larvae fed with Chaetoceros calcitrans. For the estimation standard
procedures were used.to P. monodon
