Shark populations are vulnerable to overexploitation due to their slow maturity and long gestation period. Shark fin products sold in Kota Kinabalu are not marketed according to species from which they belong. The identification of shark fms are very important to understand the number of shark fin products produced and for shark stock management by species. Thus, the aim for this study is to help in identifying species or the family based on the fin morphology. The combination method of using light microscope and digital camera were useful for shark fin morphological characteristics observation. The denticles characters, fin shape and coloration of five species sharks from family of Carcharhinidae, Hemiscyllidae, Sphyrnidae and Squalidae, and a batoid from Rhinobatidae were different from each other. Hence, these characteristics were able to separate the sharks into species or at least the family they belonged. Moreover, the shape of skinned shark fins and structure of fin rays are also available for separation of smaller group. The distribution channel of shark fins in Kota Kinabalu was obtained by personnal communication with several shark fins traders involved in shark fins products in Kota Kinabalu. These traders were seafood whole sellers, trawlers, fish mongers and shark products hawkers.
