Grouper & Seabass

Group 5: Heavy body / Large lips

Grouper & Seabass

Group 5 - Heavy body / Large lips : Heavy bodied, large lipped fish belong to the seabass family. We tend to refer to the larger seabasses as groupers and the smaller seabasses as bass or basslets. These fish are extremely important food fish and are under increasing threats from heavy fishing pressures. Monitoring these fish can help provide valuable data to aid in their protection. Most seabasses are hermaphrodites, meaning the same fish will be both a male and a female during its lifetime. The groupers are all born female and later change sex to become male. Most large groupers also congregate each year to spawn at a specific location, making them easy targets for emerging positioning and fishing technology.

5 Fun Facts - Groupers

Intriguing and diverse, groupers are not only impressive in size but also fascinating in their biology and behavior. There are approximately 160 species of groupers. Here's all you need to know about snappers, along with some fun facts:

Vocal Communication: Groupers are known to produce sounds, such as grunts and thumps, using their swim bladders. These vocalizations serve various purposes, including territorial defense and courtship.

Size Matters: Groupers are known for their impressive size. Some species can grow to be as large as 9 feet (2.7 meters) long and weigh up to 800 pounds (363 kilograms)! The Atlantic Goliath grouper is particularly famous for its massive size.

Changing Sex: Groupers are known for their ability to change their sex during their lifetime. They are protogynous hermaphrodites, meaning they start as females and may transform into males as they grow older and larger.

Longevity Champions: These fish are some of the longest-lived marine creatures. Some groupers can live for several decades, with some individuals reaching 50 years or more.

Master of Ambush: Groupers are skilled predators that employ an ambush hunting strategy. They patiently wait for their prey to come close and then use their powerful jaws to quickly engulf their meal.
