Aspek Biologi Reprodusi Ikan Selar Kuning (Selariodes leptolepis) di Perairan Selat Malaka Kecamatan Medan Belawan Provinsi Sumatera Utara

Abstract

Yellow trevally fish is one of the economically important fish species.fish Theseare used as raw materials processed fishery products such asfish, salted grilled fish, boiled, fishmeal and surimi. Besides these fish are also traded in a fresh state. Based on the statisticsfisheries of the oceanFishery Port of Belawan 2011-2016 decline in production and an increase in fishing effort that resulted in catch per unit effort (CPUE) declined yellow trevally fish. The condition is feared to intrusive yellow trevally fish resource sustainability, so that the necessary their basic yellow trevally fish management in order to remain optimal, sustainable and among other sustainable approach to biology reproduction. Research on the biological aspects of reproduction yellow trevally fish are still rare. Therefore, this study aims to know some aspects of the reproductive biology of fish yellow trevally. Biological aspects of reproduction covers the frequency distribution of the length, length relationship weight, the size of the first ripe gonads, sex ratio, gonad maturity level (TKG), gonad maturity index (IKG), the diameter of the eggs and the fecundity and histology. The method used is the method of fieldsurvey.Data primer used is long and body weight, gonad weight and fecundity obtained from the results of sampling in the field. Data is collected from March-May 2017 with an interval of 30 days. Fishing using fishing methods representing the entire class size long. Fish obtained as many as 360 birds. Secondary data was collected from Fishing Statistical Report PPS Belawan amount of production, and fishing effort of the year 2011-2016. The results showed the frequency of fish length of 110 mm - 163 mm. Character growth negative allometric with a correlation coefficient (r) males and females close to 1 that each - each 0.812 and 0.733. Aspects of reproduction in fish Selar Yellow for sex ratio is in balance. Selar fish gonad maturity index Yellow females larger than males Yellow Selar fish. Gonad maturity level obtained by the I, II, III, and IV. The first measure Selar fish gonads mature males larger than females Yellow Selar fish. The fecundity of fish ranges between 10346-99905 grain and based on distribution hose diameter size class heterogeneous eggs suspected nurseries patterns are partial spawner
