Breeding performance of green back grey mullet Liza subviridis (Valenciennes 1836) from coastal water of the Bay of Bengal

Abstract

Berried females of Liza subviridis (Valenciennes 1836) were collected from the fish landing centers of Cox’s Bazar (Bay of Bengal) to estimate the maturity stages, gonado somatic index (GSI), ova diameter, fecundity, breeding time and both the macroscopic and microscopic appearance. Data were collected for consecutive 6 months following seasonal patterns. Study revealed that the breeding period of Liza subviridis (Valenciennes 1836) was found to occur from last December to January with January as peak. The GSI ranges from 0.83 to 25.71. The ova diameter was found ranging from 0.07 mm to 0.60 mm and highly related with mean GSI. Fecundity was calculated to be 32,010 to 1,86,662, which showed high fecundity compared to other marine fish. There was found no significant correlation between fish weight and body length of Liza subviridis.
