The length weight relationship and condition factors of Tank Goby Glossogobius giuris Hamilton, 1822 in Lapompakka Lake, Wajo Regency, South Sulawesi

Lapompakka lake is one of the inland waters located in Tanasitolo District, South Sulawesi. Tank goby is one of the main commodity fish in Lake Lapompakka. This study aims to analyze the length-weight relationship and condition factors based on sex, observation time, and gonad maturity of tank goby. The results of this research are expected to provide information on growth patterns and conditions factor of tank goby so that they are useful in determining sustainable management and utilization efforts for tank goby conservation. This research was conducted for three months (September - November). Tank goby samples were obtained from 2 fishermen who were fishing in Lapompakka Lake. Analysis was conducted at the Laboratory of Fisheries Biology, Department of Fisheries, Faculty of Marine and Fisheries Sciences, Hasanuddin University. The number of fish was 212 individuals, composed of 153 males and 59 females. The results of the analysis, the growth patterns of male (b = 2.4667) and female (b = 2.3770) tank goby have a negative allometric growth pattern, which indicates the increase in body length is faster than the increase in body weight of the tank goby. The value of the condition factor indicates that the tank goby is in good condition and are in the fat or plump category that the condition factor of the tank goby increase along with an increase in the level of gonad maturity.
