Gulf Coast fish species

Grouper in the Gulf of Mexico

  • The Gulf of Mexico is home to many commercially valuable fisheries species, including stone crab, shrimp, snapper, and grouper.
  • Groupers are a type of fish called serranids, and are members of the family Serranidae. There are many species of grouper.
  • They are teleosts, a group of fish identified by their stout bodies and large mouths.
  • The goliath grouper is the largest of the groupers and can grow up to 800 lbs.
  • Groupers do not swim quickly over long distances. ch. Their mouth and gills form a vacuum, inhaling prey from a few feet away and swallowing it whole.
  • Grouper eat smaller fish, octopus, crab, and lobster.
  • Groupers are protogynous hermaphrodites, meaning they are born female but transform into males when they reach a certain size. They reproduce by spawning (releasing large quantities of eggs and sperm into the open water) during the summer months.
  • The commercial fishing (fishing for profit) of groupers is a multi-million dollar industry in the Gulf of Mexico.
  • Grouper is a popular item on seafood menus and attracts many tourists to Florida communities and restaurants, therefore boosting local economies.
  • Grouper is also a popular sport fishing target.
  • Groupers’ commercial and recreational value makes them one of the most overfished species in the Gulf of Mexico. Overfishing is the harvest of fish from a body of water faster than they can reproduce. t is not sustainable, meaning that the grouper populations will eventually collapse.
  • Since the 1950s, grouper populations in the Gulf of Mexico have declined rapidly.
  • Recall that groupers morph (change) from female to male when they reach a large size. Fishermen typically harvest large male groupers because they are more valuable than smaller females. This behavior disproportionately removes more males than females from the ecosystem, making it difficult for groupers to reproduce successfully. As a result, grouper do not easily recover from population declines, even when fishing is heavily regulated.

Cats threaten endangered species.

GAINESVILLE, Fla. - With 4 million to 6 million unwanted animals - mostly cats - put to sleep each year in the United States, some people might consider it more humane to free the felines into the wild.
But as these cats forage for food and establish their territories, they kill more than a billion small mammals and birds each year, many of which are threatened or endangered, a University of Florida study shows.
Feral, or free-roaming, untamed cats pose a serious threat to endangered species nationwide as colonies of the wild cats have grown, largely because local groups provide funding and resources to sustain them, according to the UF study commissioned by the U

“This allows the predator fish to feed heavily on the forage fish species. Consequently, the predator fish species are fatter and healthier during the next years spawning season,” she explained.
