Introduction
Epinephelus cyanopodus, commonly known as speckled blue grouper, is a salt water fish.
Who is it?
Genus Epinephelus
In 2019, the genus Epinephelus comprised 87 species according to FishBase. These fish are commonly known as "groupers" and belong to the "serranid group" (Serranidae).
They are territorial carnivores with elongated and robust bodies. They have imposing heads with canines in the front of their jaws and protractile mouths. All species possess 10 or 11 dorsal spines.
Most species are found in coral reefs or rocky areas, with some exceptions (such as E. aeneus, E. bruneus, or E. areolatus) living in sandy, muddy, or silty bottoms. Adults are typically observed at depths ranging from 10 to 200 meters. Most Epinephelus are recognized as protogynous hermaphrodites, meaning they are born as females and become males as they grow. However, not all females may change sex, and some males may not go through this commonly accepted stage.
These fish are highly valued commercially for consumption and recreational fishing, but they are vulnerable to overfishing due to their slow growth, late maturity, and the formation of reproductive aggregations. Overfishing, particularly targeting mature individuals, can lead to sex-ratio imbalances and affect reproduction. Several groupers are now the subject of aquaculture farms (especially E. coioides and E. malabaricus).
According to the IUCN, overfishing and pollution have already caused a significant decline in the populations of many groupers, and several species are endangered.
