Abstract


Yellowstipe scad fish is an economically important fish because it is tasty and affordable. This study aims to analyze the growth rate, mortality, recruitment of yellowstipe scad fish (Selaroides leptolepis) and information about the management of small pelagic fish resources in the waters of Bintan. This research was carried out in February-June 2019 at the Barek Motor Fish Landing Area (TPI) with fishing areas in Bintan waters. The number of fish studied was 2700 with a length of 10.2-21.5 cm and a weight of 15-102 gr. The relationship between the length of yellow yellow fish with the value of b every month is less than 3 (b<3) which is the growth of yellow yellow fish as allometric negative. The growth equation of yellow-yellow fish is Lt = 23,41[1-e-0.81(t+0,2118)]. The highest recruitment peak occurred in June of 19.48%, followed by April of 18.11%. The highest and lowest condition factors are 0.52 and 1.09. The total mortality rate (Z) of yellow strait fish is 4.61 per year with a natural mortality rate (M) of 1.66 per year and the capture mortality rate of 2.95 per year so that the exploitation rate is 0.63. The dheate of yellowstipe scade fish in the Bintan Sea  mostly caused by fishing activities (F) of 2.95 per year.
