Abstract

Laboratory spawning of a mature female Metapenaeus dobsoni obtained
from the Cochin Backwater and kept in the brackish water medium (salinity
30.22%o, temperature IT.S'C) is reported. The eggs reared in the brackish
water medium hatched out into nauplii, but none of them developed further.
On transferring a few nauplii to the sea water (salinity 34.02%o) after two days,
they transformed into abnormally developed protozoeae. The importance of this -
observation in the context of breeding of Indian penaeid prawns and from the
point of view of their culture in the coastal estuaries is pointed out.
