Pertumbuhan Dan Laju Eksploitasi Ikan Tuna Sirip Kuning (Thunnus Albacares) Berdasarkan Musim Yang Didaratkan Di Gedung Prosesing Pelabuhan Perikanan Samudera Bungus Provinsi Sumatera Barat (Studi Kasus Tahun 2018)

ABSTRACT
Yellow Fin Tuna is one of fisheries commodity that has high economic value in Sumatera Barat. This type of fish is the most demand in the local market, thus it becomes the main target catch for fisherman. This study was done at Building Procesing on January 2018, and the aims were to study about the growth pattern, growth parameter, factor condition, and also the rate of exploitation in order to provide appropriate management model for the fish resource. The primary data is the total length and wet weight of 8.174 samples of Yellow Fin Tuna. The cohort length of fish is separated by Bhattacarya method in FISAT II software. The Von Bertalanffy growth parameters estimated were asymtotic length (L∞) = 191,1 cm, growth coefficient (K) = 0,84 year-1 and the age at zero length (t0) = 0,01 from Pauly’s empirical equation. Then, the growth equation for Yellow Fin Tuna is Lt = 191,1*(1‐e[-0.006(t+1,5)]), whereas value of b obtained from relations of lenght – weight Yellow Fin Tuna is 2,545. A growth pattern of Yellow Fin Tuna is negative allometric with an equation growth W= 0,00002L2,545. The highest and the lowest value of factor condition are 0,17 and 4,89. The rate of total mortality (Z) Yellow Fin Tuna is 4,37 year-1 with natural mortality rate (M) 0,97 year-1 and fishing mortality rate (F) 3,4 year-1 thus the rate of exploitation is obtained with the amount 0,78 and the value of this exploitation rate has exceeded the value of the optimum exploitation, which is 0,5.
