Trained dolphins have been serving people ever since the Second World War. Now, Man has finally managed to domesticate dolphins in their natural habitat and utilise their intelligence for his own means. Now, dolphins help man to fish – just as was the case with dogs and hunting.
Dolphin language is decrypted. They are commanded to find fish and make them swim to the designated location. Thus, they direct schools of fish to fishing vessels using their sonar and innate instincts.
More than that, fish farms in the wild are widespread. There, dolphins also make an invaluable contribution as underwater herders.
