Abstract

The development of fisheries in the consisting area from various aspects, one of them from the biological aspect. The biological aspects has important effort for fisheries development in the area. Biological aspects for this research is useful to know composition of gastric yellowfin tuna that landed on Pasar Lama. A total of 30 sampled gastric yellowfin tuna taken on September 2015 to January 2016 from a fisherman at the Pasar Lama for the measurement of the total-length, total-weight, length-weight correlation analysis, and analysis of the gastric with frequency of occurrence method, volume organism method and preponderance index. The data has been calculated between correlation from total-length and total-weight of yellow fin tuna was positive allometric with b values is 4.22. The result from preponderance index calculation of squid is 81.77%. Based on the conclusion, squid is main food for yellow fin tuna in Pasar Lama Kaur and based on the length-weight correlation analysis is allometric positive results obtained in which the growth of yellow fin tuna weight faster than the growth of length.
