Bycatch landing in Thailand has increased from 787,000 t in 1980 to 803,000 t in 1984 accounting for 40% of total marine production. Increased landings, in combination with the over exploitation of marine fisheries and declaration of the 200-mile exclusive economic zone of the neighboring countries have had a disastrous effect on domestic fish supply in Thailand. Bycatch and other under-utilized species need to be better utilized for human consumption. Problems encountered in utilization of such species include poor quality of fish upon arrival at the landing places, small size and variation in shapes and species which have different flesh characteristics. Because of limitation in product storage life of bycatch handled onboard, sorting and icing should be confined to the last two weeks of the trip lasting 22 days. Studies on yield and storage life of minced sorted bycatch show that approximately 50% is fit for human consumption. The storage life of minced bycatch at 7 deg C is seven days; minced washed with diluted salt solution (0.2-0.3) has a 13-day storage life. A number of products from bycatch have been developed. Also, its potential for industrial processing is demonstrated.
