Abstract
Yellow stripe trevally (Selaroides leptolepis) is one of the main catch species of seine net (local: cantrang) and is one of the potential demersal fish resources. Yellow stripe trevally fish have high nutritional value and economic value. The great benefits of yellow stripe trevally fish and increased exploitation. This research was conducted at UPT PPP Bulu in February-June 2019. The purpose of this study was to determine the biological conditions and determine the requirements of the population dynamics of yellow stripe trevally fish. The method used in the study is descriptive quantitative with random sampling and to analysis the data using Microsoft Excel and FISAT II programs. Based on the analysis of the biology aspects of fish with a total sample of yellow stripe trevally fish (Selaroides leptolepis) were 535 fish. The relationship between the length and weight of the yellow stripe trevally fish was negative allometric Comparison of male and female sex ratios was 1:1,03. The percentage of gonad maturity (TKG) was 60% Mature and 40% Immature. The gonad maturity index (IKG) value is 2,88%. Length at First Capture (Lc) of 14,51 cm. Length at First Mature (Lm) of 16,24 cm. The growth rate obtained (L∞-) of 20,03 cm, the growth rate coefficient (K) was 1,25 per year, and (t0) is -0,140 years.
Keywords: Length at First Capture (Lc), Length at First Mature (Lm), population dynamics
