Abstract:
The broad objective of the present study is to present a synoptic picture of the distribution and abundance of fish eggs and the lmportant groups of fish larvae obtained off the SW coast of India. so as to delineate the spawning areas and seasones of the fish population. with special reference to the scombroid fishes. An attempt was also made to correlate the occurrence of certain categories of larvae and hydrographical factors like
temperature and salinity. The present effort was a pioneering one in Indian waters. in as much as it involved systematic and seasonally repetitive collection of ichthyoplankton from a large
stretch of our seas and mapping of their distribution and abudance.

Abstract:
The main objectives of the present study has been the collection of the
larvae of some of the important and less studied demersal fishes of the South,
West Coast of India, preparation of their life history series, statistical analysis
of the morphometric characters, spatial as well as temporal distribution of the
larvae in relation to the chief hydrographic parameters such as temperature,
salinity and oxygen, so as to delineate the spawning areas and seasons of these
fish populations. The informations regarding the kind and amount of bottom fish resources along the Indian Coast are scanty. Even though the flat fish resources of Indian waters contributes a singificant share in the total marine fish landings the detailed studies on biology and fishery have been conducted only for ‘Malabar Sole‘ (Cynoglossus macrostomus) while the reminder species of this group are inadequately known. Lizard fishes (order Myctophiphormes) are always present in the miscellaneous catch in all seasons but an adequate knowledge of the potential resources of this group is wanting. The Bombay duck, coming under the same order, is one of the most heavily fished species particularly along the Maharashtra Gujarat coasts but its early developmental stages are not studied. Hence the present study will contribute to a better understanding of the demersal fishery resources of the South West Coast of India
