Abstract

The development of fisheries in the consisting area from various aspects, one of them from the biological aspect. The biological aspect has important effort for fisheries development in the area. Biological aspect for this research is useful to know composition of gastric yellowfin tuna that landed on PPN Palabuhanratu. Sample yellowfin tuna taken on August 2015 to December 2015 from a fisherman in the PPN Palabuhanratu In the operation of tonda fishing vassel, haved 4 types of fishing gear used are taber, tomba, fishing line, and kite which have different type and function of catch. for the measurement of the total-length, total-weight and length-weight correlation analysis. The data have been calculated between correlation from total-length and total-weight of yellowfin tuna were issometric with b values 3.304. The total length of tuna madidihang obtained in total ranges from 39-68cm FL. The long-term frequency distribution of tuna madidihang for five months is dominated by the size <100 cm FL. Based on the observation of the fishing fleet of tents, each fishing gear used has different ways of catching operations with different catches. Madidihang in PPN Palabuhanratu and based on the length-weight correlation analysis is issometric results obtained in which the growth of yellow fin tuna weight normal with the growth of length but to much jouvenile to catch with this fisshing vassel, it have lokked at leght distribution analysis 55% are have juvenile leght.
