The snakehead (Channa striata) in Sungai Batang River, Indonesia has high commercial
value and high pressure on population caused by fishing. Meanwhile, scientific information on
morphometric characteristic of snakehead is still lacking. Samples of 330 fishes having size
range of 75–335 mm (202.68 ± 46.56 mm) total length (TL) and 9–288 g (81.23 ± 53.95 g) weight
were taken to estimate length-weight relationship and condition factors. The snakehead grew
allometrically (b = 2.6927–2.9125), indicating that fish becomes slender as the length increases.
Total length and weight of female were significantly higher than male (P < 0.001). The highest
number of catch was found between 160 and 179 mm TL (24.44%) for male and between 260 and
279 mm TL (16.00%) for female. The heaviest catches of male (33.89%) and female (14.00%) were
noted between 30 and 49 g weight class. The mean condition factor (K) value of female was
considerably higher than that of male (P < 0.001). The mean K values obtained for male and
female were 0.83 ± 0.09 and 0.86 ± 0.08, indicating that the fish in the river was unfavorable
condition.
To the best our knowledge, this study is the first reference on length-weight and condition
factor for snakehead from this river. |
