Grouper species
Grouper are members of the seabass family. They have heavy, stout bodies and large underslung mouths. Species may vary in size from 1-7ft. Grouper are solitary bottom dwelling carnivores that live in the protection of reefs, ledges and wrecks. Many grouper species can dramatically change colour or darken.
Grouper are slow growing, but are long lived. Most grouper species change sex during their lives, usually from female to male, so that larger fish are usually male. This phenomenon is called ‘sequential hermaphroditism’ and does not occur as previously thought in Nassau grouper. The relationship between age and sex may cause decline of some grouper species since, catching larger fish removes breeding males from the population.
Grouper are under heavy fishing pressure for their excellent meat. Overfishing of grouper has resulted in a decline of the species throughout the Caribbean. Measures have been put in place in many territories to protect them. These include closed seasons, establishing marine reserves and fishing prohibitions.
