Description Cynoglossus macrostomus formed 93 % of the annual average landings of
flatfishes (3951 t) during 1993-2004 at Calicut. The fishery showed annual
fluctuations. Peak landings were recorded during December-April. Growth
parameters of this species were L! = 164.5 mm y-1 and K = 0.70y-1. The fish
grows to 83, 124 and 146 mm at the end of 1-3 years. The total and natural
mortality were 3.01 y-1 and 0.91 y-1 respectively. The length-weight relationship
shows that the growth is isometric and there is no significant variation between
sexes. The spawning is prolonged with two peaks. The length at first maturity
is 102 mm. Females dominated the fishery. The stock is exploited marginally
below the optimum level at present. The total and standing stock of this species
along the Calicut coast is estimated as 5430 t and 1720 t respectively.
