Early life distribution of gold spotted grenadier anchovy Coilia dussumieri valenciennes, 1848 at ye river estuary, southern mon coastal water

Abstract

The pattern of the use of the Ye River Estuary euryhaline area in southern Mon coastal water by Coilia dussumieri was investigated to assess spawning period recruitment and to detect spatial temporal patterns of this major fishery resource Fishes were sampled by seine nets from early premonsoon to postmonsoon and by beach seine from premonsoon to postmonsoon Reproductive season measured in terms of GSI gonad development and appearance of recruits indicate that reproduction occurs from August to March when they reach the best condition Recruitment peaks in post and pre monsoon at sandy beaches where they stay until early monsoon moving toward deeper estuary areas during late monsoon After that they join adults and perform movements between the estuary and the adjacent continental shelf to reproduce
