KAJIAN PERTUMBUHAN BEBERAPA JENIS IKAN DI PERAIRAN PESISIR KABUPATEN KUTAI TIMUR
ABSTRACT: The status of fish
populations is needed to properly manage these resources in order to maintain its
sustainability. This study aims to examine the growth factor of some fish
caught by trawl in East Kutai Regency include the length and weight relationships,
condition factor, the alleged growth, Gonadal Development Level, gonadal
Somatic index, and fecundity. The research was conducted in the sub-district of
Kaliorang, Sangkulirang and Sandaran of East Kutai regency, East Kalimantan.
Collection and measurement were conducted over a period of three months. Allometric
growth patterns are found in gerot-gerot, niko-niko, teri, senangin, gulamah,
bulu ayam dan lampa-lampa, while Isometric growth patterns found in puput.
Highest condition factor found in gulamah with the value of 1.02 and the lowest
value was found in the gerot gerot with value 0.083. The collected fish length
growth equation was senangin. The Regression equation for growth length
i.e. senangin Lt = 180,8
(1-e-1,7(t+1,25)), puput Lt = 221,5
(1-e-0,88(t+0,88)), and bulu ayam Lt =
200,55 (1-e-0,7(t+0,95)).
Keywords: growth pattern,
allometric, isometric condition factor, East Kutai Regency
