Live bait is good for grouper fishing.

Grouper are carnivorous fish that feed primarily on other small fish, crustaceans such as shrimp and crabs, and other marine invertebrates. Their feeding habits make fresh or live small fish and crustaceans an ideal bait choice.

Anglers often use small live fish, live shrimp, or fresh crabs as bait, which are effective in attracting grouper to the bait. In addition, specially treated artificial baits, such as soft roadrunners that mimic small fish or shrimp, can also be used to attract grouper. The correct choice of bait and the combination of appropriate fishing methods can greatly increase the chances of catching grouper.

Grouper, as a high-grade marine economic fish, are known for their delicate meat and delicious flavor. They are often referred to by different names such as sea cockles, chopped fish, and black catfish. In the biological classification system, grouper belongs to the order Scleractinia in the phylum Chordata, the family Serranidae under the order Perciformes, which is further divided into the subfamily Grouper.

There are 16 genera of grouper*** all over the world, including about 163 species, while 11 genera and 65 species of grouper are known to exist in China's waters such as the East China Sea and the South China Sea. There are many varieties of grouper, each with its own characteristics. Among the many varieties, the spotted grouper, red-spotted grouper, green grouper and slanted grouper are the representative varieties.

Feeding Habits

Grouper play an important role as predators in coral reef ecosystems and are known for their ferocious and voracious nature. These fish feed primarily on benthic crustaceans, other fish, and cephalopods, and adopt a raiding style of feeding. When food supply is low, grouper sometimes exhibit cannibalistic behavior, especially in the juvenile stage.

Smaller individuals are more likely to become prey for larger individuals. Grouper are very sensitive to water temperature and their optimal living water temperature range is between 22 and 28 degrees Celsius. When the water temperature drops below 19 degrees Celsius, the grouper's appetite diminishes, and they will refuse to eat dead fish or other dead bait when the water temperature drops below 10 degrees Celsius.
