Blue Sharks are highly migratory and can travel long distances in search of food and suitable breeding grounds. They have been known to migrate across entire ocean basins.
During mating, male Blue Sharks will bite the female's pectoral fin and position himself on top of her. This behavior is known as the 'mating scar.'
They do not have a specific migration pattern.
Blue Triggerfish are sequential hermaphrodites, which means they change gender as they grow. They start as females and later become males.
Blue Whiting undertakes seasonal migrations, moving north during the summer and south during the winter.
Blue Whiting spawns in mid-water, where the eggs drift with the currents.
Bluefin Tuna are highly migratory fish, traveling long distances in search of food and suitable spawning grounds. They can migrate thousands of miles between their feeding and spawning areas.
Bluefin Tuna undertake long migrations to specific spawning grounds in order to reproduce. During spawning, males and females come together in groups and release their eggs and sperm into the water simultaneously.
Bluefish are known to migrate long distances in search of food and suitable breeding grounds. They can migrate from the wintering grounds in the south to the northern feeding grounds in the summer.
Bluefish spawn in warm coastal waters, with peak spawning occurring in the spring and summer months.

Bocaccio has a limited migratory pattern, with some individuals moving between deeper waters and shallower areas during different seasons.

Spawning
Bonefish are known for their extensive migration patterns. They often move between shallow flats and deeper offshore waters.
Bonefish typically spawn in deeper waters near the edges of flats or on the outer edges of reefs.

Some populations undertake seasonal migrations
Mating occurs year-round, with peak activity during the summer
