Within the last ten years, bluefin tuna fishing grounds are becoming extremely profitable as a result of the huge need by the sushi as well as sashimi industry. Based on the very last analysis of the bluefin tuna inventory in the East Atlantic and also the Mediterranean, the expansion in fishing pressure has triggered a sharp decline in the public along with a radical decrease of reproducers’ biomass. This occurrence has triggered great problem for the survival of this particular species.

Adult bluefin tuna species are able to exceed three m in length. Like almost all fish, egg production appears to depend on age (or maybe size). Hatching occurs with no parental proper care after an incubation phase of two days.

Adult and young bluefin tuna specimens are opportunistic animals and large predators toward the food of theirs. The diet of theirs is able to include a number of species of teleostei, invertebrates including jellyfish and salps along with dimersals and sessile organisms like octopi, sponges and crabs, though great differences have been found in the places studied.
