Abstract

The study of the length-weight relationship and food habits of Pangasius polyuranodon is expected to be an input for the development of science and management of fish resources. The purpose of this study was to analyze the length-weight relationship, condition factors and food habits of juaro fish (P. polyuranodon) in Bengawan Solo River in Bojonegoro Regency, East Java. The sample of juaro fish was collected as many as 63 fish, measured in length and weight, the stomach and gut were taken, put in a small plastic bag and given a solution of formaline as a preservative. Then the gut contents analyzed in the laboratory using the index of preponderance method. The results showed that the total length of P. polyuranodon ranged from 15-51 cm; sex ratio 0.7-0.9; condition factors ranged from 1.09 to 1.23; the length-weight relationships are negative allometric with the following equation Y= 0.2x2.1048 R2 = 0.9737 (April) and Y= 0.2012 x2.1048 R2 = 0.9846 (August). Based on the preponderance index methods, P. polyuranodon is omnivorous. The main food is fish fragments (42.61%); plant fragments (26.15%), detritus (25.66%), fragment crustaceans (3.42% ) and crab fragments (2.1%).
