ASPEK REPRODUKSI IKAN TOMAN (CHANNA MICROPELTES CUVIER) DI DANAU KELUBI KECAMATAN TAYAN HILIR KABUPATEN SANGGAU
ABSTRACT: Snakehead fish
(Channa micropeltes Cuvier) is economical freshwater fish which are found in
Kelubi Lake. Over time, Kelubi lake had changed by activity around the lake and
impact on biota in it. The purpose of this research to gain information about
aspects of snakehead fish reproduction in the Kelubi Lake which involve include
density, sex ratio, level of gonad maturity, index of gonad maturity,
fecundity, and egg diameter, along with aspects of marine environment Kelubi
Lake. This research have been done at December, 2013 untill February, 2014.
Sampling technique using Proportionate Cluster Random Sampling with fishnet stocking
area 12,56 m2. Based on Catch per Unit Effort (CPUE) analyst is known snakehead
fish density in Kelubi Lake is 439 fishes. Sex ratio between snakehead fish
male and female is 2:1. Population is dominated by widhitebait with level of
gonad maturity (TKG) I. Index of gonad maturity is about 0,03-0,94%, indicates
that snakehead fish can spawn year-around. Snakehead fish fecundity as about
14.056 grains/fish and egg diameter range between 2,30-2,57 mm.
