INDICATORS OF TUNA GIGI ANJING (GYMNOSARDA UNICOLOR) GROWTH PATTERN ON THE IMPLEMENTATION OF SUSTAINABLE DEVELOPMENT GOALS (SDGS)Burhanis, Radhi Fadhillah, Zulfadhli and Edwarsyah
Tuna is a type of large pelagic fish migrating and spreading in tropical and subtropical waters. In general, Indonesian waters are one of the tuna migration routes. The waters of the western part of Indonesia, especially the Simeulue Waters in the Fisheries Management Area (WPP) 572 Indonesia. One type of tuna was found there, namely Gymnosarda unicolor species, Family: Scombridae with the general name dogtooth tuna while the local name is tuna sisik bergigi, and or tuna karang. The sustainability of tuna fish resources can be threatened if the size of the fish stock is not known, one of which is the suitable size for catching. This study examined and identified the length and growth pattern of tuna gigi anjing that were landed in fish auction area of East Simeulue. The research was conducted in May-July 2021. The data collected was in the form of fork length data. The frequency of fish length to determine the class interval was analyzed using the frequency distribution formula. Fish growth parameters were analyzed using ELEFAN 1 contained in the FISAT II program. The number of tuna gigi anjing (Gymnosarda unicolor (Ruppell)) that was successfully measured was 190 individuals. The size of the fork length ranged in the interval of 44.1 to 101.3 cm. The length of first caught tuna gigi anjing (Lc) was at 59.2 cm, the asymptotic length (Lï¥) was 98.7 cm, the growth rate (K) was 0.8/year and the zero fish growth rate (t0) was of 0.09/year.
