Fantastic Fishing

Fishing in the Pacific Ocean has just flourished lately. The fishermen now compete with each other for the title who catches the largest number of fish in one day, allowing them to develop their underwater bases even further and make the hunting itself so efficient that their competitors will stay far behind forever. You are also involved in this insane race. You've built an underwater base somewhere deep in the ocean and use the harpoons to catch as many fish as possible living in this area. Will you become a record holder in the number of fish caught on this day? Have fun.
