Catching crabs involves a unique procedure done by Goans at least once a month. This activity is considered one of the most exciting things to do during a visit to Goa. You'll need lots of skill and strength to catch and kill a crab. The trap itself is a circular metal ring with a nylon net, called “Kobllem”. Inside the trap, locals usually place rotten chicken legs to lure the crabs.
At high tide, your chances of catching crabs increase, but if you place your trap in really deep waters then low tide won't be a problem at all. Crab catching in Goa is a very popular activity, especially among fishermen and tourists. Crab meat, being succulent and sweet, is usually eaten roasted.
