The diagram illustrates the main six stages of a tuna fish’s life cycle from eggs to maturity. This cycle is divided to main two periods, such as plankton and Nekton, and those periods are represented in the figure with grey and white colours respectively.
According to the diagram, with the mating between a sexually mature female and a male tuna fish are started their life cycle. After mating, the o. o4 inches long eggs are laid by the mature female fish. In the third stage. During 24 hours, the eggs are matured and hatched. Similarly, a larvae, which survive on oil in egg sac is emerged from a mature egg. Fourthly, a tuna infant eats the huge amount of food and learns about the shoal in open water.
The diagram reveal that, from 60 to 90 days, the juvenile tuna becomes free swimmer and swim among big shoals in the fifth stage. After another time period between 15 and 30 they become mature as an adult fish, and then they are sexually mature for mating.
Overall, there are main six steps of a tuna fish’s life cycle from eggs to maturity; in first four stages tuna fish is in Plankton period and another steps they completed in Nekton period.
