Subject Prawn and Prawn fisheries
 
Description With the increased commercial importance of penaeid prawns, studies on the
larval development of this group have received much attention during the last two
decades. Although a number of penaeid prawns contribute to the prawn fishery of
India, details of larval development of only a single species, Metapenaeus dobsoni
(Miers) are known.
In the present paper, the egg, five nauplial, three protozoeal, three mysis and ten
postlarval substages of Parapenaeopsis stylifera (H. Milne-Edwards;; three mysis and
nine postlarval substages of Metapenaeus monoceros (Fabricius); three mysis substages
of M.affinis (H. Milne-Edwards); five nauplial, three protozoeal, three mysis and
seven postlarval substages of M. dobsoni (Miers); three mysis and seven postlarval
substages of Penaeus indicus H. Milne-Edwards have been described and figured.
While the larval development of these species generally follows similar pattern with
many common features, comparison of different stages reveals that characters such as
length of rostrum, presence or absence of supraorbital spine on carapace, setation of
antenna, nature of antennal scales, spination of abdominal segments as well as telson
and pigmentation show specific differences and help in the identification of the larvae
of these larval forms Based on these characters a key for the identification of the
larvae of the different species studied has been prepared. The variations recorded in
the number of substages of the larval forms have been discussed.
