SYNTHETIC FISH BAIT DEVELOPMENT USING FISH PROCESSING WASTES TO AVOID FORAGE FISH REQUIREMENT IN FISHING

Global Fish production worldwide came to approximately 174 million metric tons in 2017 (Statista 2018). For instance, fisheries sector provides food for millions of people, in this circumstance, globally 18 million tons of human consumable fishes such as sardine, mackerel, herring and squid are used annually as baits in fishing (UNO, 2014). This leads to over exploitation of human consumable fishes which in turn affect the food sustainability of marine ecosystem. Apart from this, Global fishery industrial wastes is 20% in the total fish production. It is therefore, the principal objective of the invention to provide a prepared fish bait avoiding all of the objections mentioned and solving all of these problems. With this view, three types of baits were prepared using Tuna Red Meat (TRM), Poultry Intestinal Muscles (PIM) and Fish Gelatin (FG) as the prime ingredients apart from that shrimp head waste was used as a common attractant in all the baits. Finally, the study revealed that artificial bait could be a better substitute to human consumable fishes which are used as baits in fishing as well as it shows higher catching efficiency compared to the later one and maximize the fish waste utilization, via industrial pollution can be minimized. Also, the present invention will be a big breakthrough in global seafood security through reducing the use of human consumed fish as a bait.

The baits were tested for sea water stability, fish acceptability, protein leaching and dry matter loss in the laboratory. Protein leaching rate (TRM- 4.82 mg/g/h; PIM- 11.71mg/g/h; FG-22.5mg/g/h) was found to be correlated with bait acceptability and dry matter loss (TRM- 36.6mg/g/h; PIM- 40.12mg/g/h; FG-33.15mg/g/h). Further, the artificial baits were tested for their catch efficiency in the commercial traps in comparison with natural baits. The traps baited with different experimental baits and natural baits showed significant variation with respect to catch rate (P<0.05).
