Catfish is one of potential fisheries products in Central Sulawesi, but this fact is not in line with community consumption level. Catfishes contain protein and fatty acid which are good for health. The use of catfishes as fish chips become one of the way out to increase the community consumption level. This research aims at knowing the effect of catfishes protein concentration toward chemical content (water content, ash content) and organoleptics. The research result shows that the treatment of catfishes protein concentration is unsignifficantly effect the water and ash content, besides the result of hedonic test shows that the concentration signifficantly effect the taste, the smell and the texture of catfish chips but unsignifficanly effect the colour of it. The treatment by adding 200 g of catfish was being the panels’ most favorite treatment with a score of 4.5 or with the rounding 5 indicated as favored.

White-spotted spinefoot, Siganus canalicullatus (Park, 1797) is one of the most economically importantherbivorous fish captured along the coast of Selayar Islands. The present work was undertaken to assess thelength-weight relationship and Fulton's K condition factors of this fish caught in the waters of the northern coastof Selayar Islands District. Those parameters were calculated separately for both sexes. A total of 498specimens of S. canaliculatus consisting of 265 males and 233 females were randomly collected on a monthlybasis between January and June 2015 from local fishermen using gill nets of various mesh size in the coastalwaters of Desa Barat Lambongan, Kecamatan Bontomatene, northern part of Selayar Islands District. The fishwere brought to the laboratory and, after washing, their total length (L) was measured to the nearest 1 mm usinga fish measuring board and the total body weight (W) was recorded to the nearest 0.01 g using an electronicbalance. Each fish was then cut open and the sex were recorded. The length-weight relationships of males andfemales can be expressed as log W = –4.4220 + 2.7772 log L for males, indicated hypoallometric growthpattern; and log W = –4.6840 + 2.9022 log L for females, indicated isometric growth pattern. Overall, conditionfactor values were higher in males than in females.Keywords: condition factor, length-weight relationship, Selayar Islands District, Siganus canaliculatus, whitespottedspinefoot
