Nowadays, modified lupara is widely used in tuna fish farms in order to realize the shocking-death on tunas especially blu-efin tunas (BFTs) during harvest. Some of the worldwide harvesting techniques are used wide-ly in tuna fattening farms. First of them is classical method which is divers catch to the BFTs in the pen and sends to deck and slaughtered tunas immediately on the deck. Second is electro-slaughtering technique which is used harpoon to make an electroshock to the BFTs. The other technique is shotgun which is used for especially shooting huge BFTs in the pen and a hunter use shotgun from the deck. The last one is lupara which is handy on the sea near the pen or un-der the sea by divers. The mechanism is simple and practical using, leads to the lesser stress af-fects depends on the other harvest techniques. Consequently, this study introduces to lupara, a new harvesting tool and its using technique.
