Abstract
The objective of present study was to examine the length-weight relationships and condition factor of three species fishes harvested from Ulelhee Bay, Aceh Province, Indonesia. The sampling was conducted during three month between on April until June 2015 using beach seine in Ujung Pancu Waters, Ulelhee Bay, Indonesia. The length weight relationship was calculated using Linear Allometric Model (LAM) and the relative weight was performed to assess the condition factor of the fish samples. A total of 900 fish samples (300 individual for every species) were measured for the length weight relationships and condition factor. The results showed that snapper (Lutjanusrusselli) has the b value of 3.04, indicates isometric growth pattern, while ponyfish (Leiognathus fasciatus) and white-spotted spinefootfish (Siganuscanaliculatus) have the b values of 1.41 and 1.75, respectively. These species display the allometric growth pattern. The relative weight condition factor ranges from 58.73 to 166.09 for L. russelli (101,52 in average), from 70.55 to 129.65 (100.72 in average) for L. fasciatus, and from 71.63 to 133.53 (100.59 in average) for S. canaliculatus. In general, the relative weight condition factors tended to 100, indicate the Ulelhee Bay is still in good condition and support the fish to growing well
