In fishing, "Calcutta" typically refers to a type of betting pool or wagering system commonly used in fishing tournaments. The Calcutta system involves anglers and spectators placing bets on the outcome of the tournament, particularly regarding which angler or team will catch the largest or most impressive fish.

In a Calcutta auction, participants bid on individual anglers or teams, with the highest bidder winning the right to claim a portion of the prize pool if their chosen angler or team performs well in the tournament. The remaining prize pool is often distributed among the top finishers in the tournament based on predetermined criteria, such as the heaviest fish caught or the most total weight of fish caught.

The Calcutta system adds an element of excitement and competition to fishing tournaments, as participants have a vested interest in the success of specific anglers or teams. It also provides an opportunity for spectators to engage more actively in the tournament and potentially win prizes based on their predictions and investments.

Overall, Calcutta auctions are a popular tradition in many fishing communities and are often a highlight of fishing tournaments, adding an extra layer of excitement and camaraderie to the event.
