Expert Answers

Groupers are carnivorous fish and they like to eat small fish, crustaceans, cephalopods and other creatures.

There are also some species of grouper that are filter feeders. They will filter and eat planktonic organisms such as copepods, tunicates, amphipods, and parapod larvae in the water.

If groupers are raised artificially, you can feed them more animal feed, which can speed up their growth and make them develop better. Grouper breeding methods 1. Water temperature: The most suitable temperature for grouper growth is between 22-28°C, and the lowest acceptable water temperature is 15°C. Breeders need to keep the water temperature above 20°C for them to grow normally. When the water temperature is low in winter, appropriate heating and insulation measures are needed.

2. Water quality: Groupers also have relatively high requirements for water quality. They like weakly alkaline water quality, and the pH value needs to be controlled between 7.0-9.0. And their demand for oxygen is also relatively high. The oxygen in the water needs to be 5 mg per liter. Change the water regularly to keep the water clean.
