Determination of Condition Factor (CF) and Hepatosomatic Index (HSI) of Barbonymus schwanenfeldii from Galas River, Kelantan

Abstract

The rapid growth of agriculture and industrial activities has resulted in decreasing of water qualityin the aquatic ecosystem, which is significantly hazardous for fish health. Fish are commonlysituated at the top of aquatic food chain is known to be nutritious with essential proteins. Thepurpose of this study is to determine the condition factor and hepatosomatic index of Barbonymusschwanenfeldii from Galas River, Kelantan. The sizes of slaughtered fish ranging from 319 ± 0.05to 456 ± 1.32 g in weight while 28 ± 0.34 to 36 ± 1.42 cm in total length. From a sample size of 40specimens, the average of K value was 1.15 ± 0.21 and 2.31 ± 0.13 of HSI value. Thus, the resultsrevealed that the fish species was in a poor condition. Refer to the matter; the condition of studyarea is not suitable for fish habitat. Condition factor of fishes is important biological parameterwhich can provides information on fish well-being. The condition factor and hepatosomatic indexcompares the well-being of a fish is based on the hypothesis that heavier fish of a given length arein a better condition.
