Commercial Relevance
Extremely high value, particularly in sushi and sashimi markets, where it is considered a delicacy. It is also popular among sport anglers for its strength and size
Conservation measures
Fishing quotas, minimum size limits, seasonal closures, and international agreements to manage stocks. Efforts also include research into aquaculture to reduce pressure on wild populations.
Status
Varies by species; Atlantic Bluefin Tuna is Endangered, Pacific Bluefin Tuna is Vulnerable, and Southern Bluefin Tuna is Critically Endangered.
Threats
Overfishing is the primary threat, driven by high demand for sushi. Other threats include bycatch in fishing gear, climate change affecting migration patterns and prey availability, and habitat degradation
Habitat Distribution
Depth Range
0-900 meters, with some species capable of diving deeper in search of food.
Geographic Range
Atlantic Ocean, Pacific Ocean, Indian Ocean, and the Mediterranean Sea.
Preferred Environment
Temperate and subtropical waters; open ocean and coastal areas. They are pelagic fish, spending most of their time in the open sea
Reproduction and Life Cycle
Breeding Habits
Spawns in warm waters, with major spawning grounds in the Gulf of Mexico and the Mediterranean Sea. Spawning typically occurs during specific seasons, varying by region.
Development Stages
Eggs hatch into larvae that drift with plankton. Juveniles grow rapidly, forming schools. They transition through various life stages, gradually becoming solitary as they mature.
Fecundity
Females can produce a large number of eggs, with larger females capable of releasing tens of millions of eggs per season.
Maturity Age
Varies by species; generally matures between 4-8 years, with some reaching maturity later.
