| dc.description.abstract | Channa lucius is a high economic valued fish that commonly inhabit swamp waters. As there is limited biological aspect information available, a study aims to understand reproductive biological aspects of this fish has been conducted on February – April 2012. Fish samples were caught using trap and line fishing gear. There were 40 fishes, consisted of 24 females and 16 males, 200 -330 mm SL and 4,79 - 5,97 gram weight. Sex ratio of females and males was 1:1,5. The GSI of mature males 0,02%-1,02% and that of the females were 0,16%-2,99%. Fecundity ranged from 1,592-1,907 eggs/ fish, with mature egg diameter ranged from 1.40-1.70 mm. Microscopic study of the ovarian structure showing that the ovary of the mature females consisted of eggs in several maturity levels, namely non vitellogenic, early vitellogenic and vitellogenic, indicates that this fish may be a partial spawner. The testes of males showing mature sperms throughout the study period, indicates this fish may be able to spawn throughout the year. | en_US |
