Abstract

Fish landed at fishing ports generally come from various species, fisheries management has developed into a decentralized system. Tuna is one type of economically important fish in the world and is the third largest fishery commodity in Indonesia.  The aim of this research is to determine the size composition of catches and analyze the relationship between length and weight of hand line tuna catches. Data collection techniques were carried out by observing and measuring as well as interviews with crew members of hand-line fishing boats who landed their catches at the Lonrae Fish Landing Base (FLB).  Descriptive data is presented in the form of tables and graphs. The statistical analysis used is a simple regression between two variables, namely the length and weight of the fish. Next, to get the regression coefficients, the data is processed using the graphical method provided in MS Excel software. The catch of hand line tuna boats landed at FLB Lonrae, consists of three species of tuna, namely: yellowfin tuna (Thunnus albacares), skipjack tuna (Katsuwonus pelamis) and bigeye tuna (Thunnus obesus).  The length-weight relationship of 876 Yellowfin tuna fish obtained a value of b=3.08, the length-weight relationship of 467 Skipjack Tuna fish obtained a b value of 2.71 and the length-weight relationship of 430 Bigeye tuna fish obtained a value of b=2.97 shows positive allometric growth where weight growth is faster than length growth. The tuna species composition observed at PPI Lonrae Bone Regency consisted of 3 species, namely Yellowfin Tuna, Bigeye Tuna and Skipjack. Composition of tuna species YFT=29.2% BET=11.8% and SKJ =58.97%.
