BIOLOGI REPRODUKSI IKAN BELIDA (Chitala lopis) DI SUNGAI TULANG BAWANG, LAMPUNG
Abstract: Knife fish (Chitala
lopis) is one kind of freshwater fish of high economic value.Therefore the
arrest activity continued and resulted in knife fish increasinglyscarce fish.
The purpose of this study to determine the reproductive potential ofknife fish.
Research carried out for four months in Tulang Bawang river,Lampung. Fish
samples collected from the fisherman and gatherers along therivers.
Observations were made include: morphology, length and weight, sexratio, gonado
maturity level (GML), gonado somatic index (GSI) and fecundity.Total length of
knife fish average 50,9 cm, 15,6 cm in height and weighing 883,90grams. Length
and weight relationship is expressed by the equationW=0,0459L2,5005 which means
that the type of fish growth is negative allometric.The number of knife fish
more female than male, which sex ratio between malesand females 1 : 2,3. Most
of the knife fish is immature gonads (GML I and II)with 0,35 gonado somatic
index. Many knife fish immature gonads because thefish was not spawning season.
Fecundity ranged of knife fish is 207-412 eggs oraverage of 290 eggs per fish.
