[3] They produce large quantities of eggs and their larvae are planktonic, generally at the mercy of ocean currents until they are ready to settle into adult populations. Scientific … [13][15] Groupers often pair spawn, which enables large males to competitively exclude smaller males from reproducing. Red grouper (Epinephelus morio) and gag grouper (Mycteroperca microlepis) are the groupers harvested in volume and most readily available in seafood markets.

Order: Perciformes, Family: Serranidae 'Ata'ata or Groupers and Sea Basses Serranids are known as 'ata'ata in Samoa; vary large fish may be called vaolo. Fitness of male groupers in environments where competitive exclusion of smaller males is not possible is correlated with sperm production and thus testicle size. In this study, 27 species of the Serranidae family were identified from the grouper samples collected from major fish landing sites and markets in the Philippines. Black Grouper Information. — Clean shiny belly cavity with no cuts or protruding bones. These fish have large mouths and stout bodies.

It is found in the Atlantic Ocean, Caribbean Sea and Gulf of Mexico. [13] The evolution of gonochorism is linked to group spawning high amounts of habitat cover. [5][6], In Australia, "groper" is used instead of "grouper" for several species, such as the Queensland grouper (Epinephelus lanceolatus).

Pellet-fed E. coioides were infested with 13 parasite species/taxa of which six had a monoxenous and seven a heteroxenous life cycle. However, some of the hamlets (genus Alphestes), the hinds (genus Cephalopholis), the lyretails (genus Variola) and some other small genera (Gonioplectrus, Niphon, Paranthias) are also in this subfamily, and occasional species in other serranid genera have common names involving the word "grouper".
