Abstract

Gravid females of Metapenaeus dobsoni (Miers) collected from the fishing
grounds oS Cochin spawned in the laboratory and the larval development was
traced up to Postlarva IV. After 8-9 h of spawning, Nauplius I larvae emerged
imd they reached Protozoca I, after moulting five more times in 43.30 h.
Undergoing two more moults, these larvae attained Mysis I in 178.30 h. These
mysis larvae metamorphosed to the Postlarva I, after passing two more substages
in 321.30 h (13 days and 8 h). Brief descriptions of the various larval stages
are given.
