Description The penaeid prawn Metapenaeus dobsoni (locally known as poovaalan in the bigger
sizes and thelly in the smaller sizes) spawns in the inshore waters of the Southwest coast of
India (Menon 1951) almost throughout the year with the peak breeding season between
June, July and November (Menon 1955 and George 1962). The eggs hatch and through
different stages quickly transform to postlarvae which are noticed to enter in very large
numbers into the various estuaries and backwaters along the coast and to use these waters
extensively as nursery grounds during their juvenile growth period. The very lucrative paddy
field prawn fishery and the backwater fishery for prawns of Cochin and other areas of the
coast is singularly dependent on this habit of the prawn. After a growth of about 9 or 10
months these prawns return to the coastal waters where they are henceforth exploited by
both the indigenous fishing as well as the mechanised fishing operations.
