MSY and FMSY for shrimps targeted by trawlers in Maharashtra were estimated as 44,647 t and 7.75 million trawling hours. The optimum number of trawlers in the state was computed at 2,778 as against present fleet of 5,613, indicating overcapacity in the trawling fleet.
Average annual all India trawl landings for the period 2008-2011 is 17,21,000 t. which formed 51 % of the total marine fish landings in the country.
