Lenght-weight relationship and condition factor of huluu fish (Giuris margaritacea) in Limboto Lake

Abstract

Giuris margaritacea (Valenciennes), the snakehead gudgeon is a species of fish in the family Eleotridae, live in Limboto Lake. Decline in the quality of the lake water, sedimentation lakes and eutrophication give bad conditions resulting to Limboto Lake. Diversity resources fishing lake has degradation. Population the fish original and important has decline, one of that is huluu fish, increasingly difficult to found. The purpose of this study is to find out lenght- weight relationship and condition factor Huluu fish (Giuris margaritacea) in Limboto Lake. The research was done in april until june in Limboto Lake with 7 points of sampling in Limboto Lake. Sampling was carried out by purposive sampling, Data analysis used to this research is Model Allometric Linear (LAM) used to calculate parameter a and b through the measurement of changes in lenght-weightt and condition factors. The result of this research known that fish huluu derived from Limboto Lake generally have model growth allometric positive (b>3) with the condition factors range between 0.12 - 1,91 whereby the meaning of the amount is fish categorized as flat fish.
