English Abstract
Nomei (Harpadon nehereus) in Juata Laut waters, Tarakan are caught using “pukat hela” (small trawler) that fits the muddy character of the sea, producing nomei with various sizes and biological attributes (such as growth and age structure). This research intends to see the trend of biological condition in order to provide actual data for the management of sustainable nomei resources. The result shows that female nomei have longer body and more weight compared to the males. The length of male nomei grows approximately L∞ = 37,658 cm and maximum age of 951 days with value of K= 0,0146 cm/day and t0 = -1,082 cm. The female fish can grow up to L∞ = 38,535 cm and maximum age of 813 day with value of K = 0,0159 cm/day and t0 = -1,039 cm. The male fish grow fast in the day 0-142 up to 32,995cm and grow slow in day 143-277 up to 37.008 cm and constant grow after day of 278-951.7 at L∞. The female fish grow fast in the day 0–170 up to 35.995 cm and grow slow in day 171–365 up to 38.420 cm and constant grow after day 366-813.7 at L∞.
