Abstract

• Reproductive biology of Gazza minuta was studied by using the samples collected from the catches of trawl fisheries in Myeik coastal waters during January to December 2014. Spawning takes place throughout the year, with peak in June-January. The observed length at first maturity was 9.5 cm total length in males and 10.0 cm in females. The gonadosomatic index value was more prominent in females than in males. Sex ratio also indicates the general dominant of females over males. Fecundity varied from 10,002 to 69,421 eggs. Fecundity has positive relationship between fish length, fish weight and ovary weight of fish.
