Abstract
The pharaohs cuttlefish Sepia pharaonis were cultured in a semi-closed water system through multiple generations. Eggs of S. pharaonis landed in overnight crab nets gill nets and shrimp nets were collected and brought to the laboratory incubated and the hatchlings were maintained throughout their life cycle. The hatchlings from the eggs collected from the wild were called G1 generation. Subsequent generations were named as G2 and G3 generations. Incubation period for the eggs were 213 days 212 days and 211 days respectively for G1 G2 and G3 generations. The hatchling behaviour as well as feeding and reproductive behaviours were recorded. Brine shrimp and post larvae of Acetes indicus were given during the initial days of culture but switched to dead fish after 40 days. Daily growth rate was noted to be 0.72 mm in G1 0.52 mm in G2 and 0.2 mm in G3 generations respectively. Using simple and inexpensive filtration system Sepia pharaonis can be reared to marketable sizes in fishermens backyards and serve as an additional source of income. This technique could also be employed in sea-ranching projects of S. pharaonis.
