Description 841-846
Though majority
of research findings suggest recirculation systems (RS), the present work was
experimented with a closed circulation system (CCS). Successful growth rates
were evident up to 130 days where the average dorsal mantle length (DML) was 84
mm and weight 61.43 gms. Effect of salinity on the pralarva at various levels
displayed 100% survival rate in the range of 30-34 ppt. Though brine shrimp (Artemia parthenogenetica) was the
preferred prey for the first 10 days of culture, Paralarva fed with mysids had
better growth rates from 10th day onwards. Higher survival rate was
noted (78%) for Paralarva fed with mysids. The juveniles were trained to accept
frozen mysids after 21 days while flesh of fish (Johnius dussumieri) was introduced from 40th day
onwards. In par with the cultures from recirculating systems, closed systems
are effective for culture of the Pharaoh’s cuttlefish. Though growth rates tend
to be on a negligible lower level, it is evident that these cephalopods can be
raised without much of an investment under the CCS.
