there was this great fisherman who lives on the West Coast since four generations! He explained what fishing torpedo is all about. There is this big line that can reach out up to 2km in the sea. There are 25 hooks fixed at the end of the line. It stays there for approx.1 hour. Then u check the prey. And we caught 6 sharks! Spotted fish that are known as lemon fish. U get them for 50 bucks/kilo. The white spots on the fish mean the shark has no teeth and can't bite u. I was told that in Europe fisherman cut the fins off(to make soup of it) and throw the body away to the sea- That's a crime against nature.
