Larval history of Caridina longirostris H. Milne Edwards

N. N. Pillai

Complete larval history of Caridina longirostris was studied by rearing them under controlled conditions. Eight distinct zoeal stages and one intermediate stage were distinguished during the development from first zoea to first post-larva, which required a minimum of 15 days duration. First post-larvae were reared for 173 days, by which time, majority of them had developed to adult stage. A brief description on the major transformations of the appendages during the development of first post larva to adult stage is also provided. The salinity of the rearing medium varied from 6 to 10%0 and ambient temperature from 23 to 280C.
