COMPOSITION, SIZE DISTRIBUTION AND CAPTURE RATE OF FLOAT-OPERATED LIFT NET IN PALABUHANRATU BAY, SUKABUMI
Abstract
The number of fishing gear operating in a fishing area will have an impact on increasing competition to get the fish caught. This will affect the composition of the fish, size distribution and catch rate. This study aims to analyze the composition of fish, size distribution, and catch rate in the current operation of the Float-operated lift net from February to April in Palabuhanratu Bay. The fishing operation was carried out as many as 20 trips to collect data on fish size (TL and W) and fish species. The composition analysis was carried out by calculating the proportion of the catch, the size distribution analysis was carried out using the class interval calculation approach and the catch rate analysis was carried out by the Catch Rate (CR) calculation. The results showed that the catch composition consisted of three group of species, namely 1 species of pelagic fish, 3 species of demersal fish and 1 species of molluscs. The composition based on weight was dominated by Tembang Fish (S. fimbriata) with a proportion of 43.27%, while based on the number of individuals found was dominated by L. equulus with a proportion of 91.50%. The dominance of different TL sizes for each type of fish. The dominant TL size was caught for Loligo sp and L. equulus at 3-6 cm TL interval, M. maculata at 19-22 cm TL interval, T. savala at 35-38 cm TL interval, and S. fimbriata at 15- 22 cm TL interval. 18 cm. Based on the size of the individual fish caught, the size of the weight caught for Loligo sp was dominated at the W interval of 70-91 gr, M. maculata at the W interval of 180-201 gr, T. savala at the W interval of 4-25 gr, L. equulus at the interval of W. W 4-25 gr, and S. fimbriata at intervals W 180-201 gr. The catch rate of Floating Chart per fish species is in the range of 0.03-2.37 kg/hour. The highest catch rate was found in S. fimbriata at 2.37 kg/hour and the lowest was T. savala at 0.03 kg/hour.
