ABSTRACT
CHERIN MONALISA SIRAIT. Relationship of Length Weight with Gonad Maturity Index of Fringescale Sardine (Sardinellafimbriata) in LabuCoastal Waters at Deli SerdangDistrict of North Sumatera Under AcademicSupervisor by HASAN SITORUS and ANI SURYANTI.
The objectiveof the research was to determine the growth and rerproduction aspects based relationship of length weight with Gonad Maturity Index (IKG) of Fringescale Sardine (Sardinella fimbriata).The researchhad been conducted in Labu coastal water, Deli SerdangDistrict of North Sumatera Province for 3 (three) months starting from November 2014 until January 2015. The result are expected to be a source of information that useful for fish resource management to gain the optimal and sustainable utilization.The number of fish samples was 270 fishes which consist 119 female fishes and 151 male fishes. The result showed that the length range of female fishes waslarger than male fishes. Female fish growth pattern was isometric, and male fish was negative allometric.Conditions factor and IKG of female fish was larger than male fish. The correlation of length weight with IKG of fish was strong.
