CATDOLL : CATDOLL: What are the habits of redfin fish?

Yellowfin snapper, also known as yellow wall, yellow foot, red wing, etc. It belongs to the family Sparidae of the order Perciformes and is widely distributed in the Red Sea, the Arabian Sea coast, India, Indonesia, Japan, North Korea, the Philippines and the offshore waters of China. It is one of the important economic fish species along the coast of South China.

1. Ecological habits Yellowfin snapper is a shallow warm-water bottom fish that likes to live in rocky reef areas. The water temperature range of young fish is narrower than that of adult fish. The optimal temperature for survival is 9.5-29.5℃, and the optimal temperature for growth is 17-27℃. Adult fish can withstand low temperatures of 8℃ and high temperatures of 35℃. Yellowfin snapper can adapt to drastic changes in salinity. It can be directly put into fresh water from seawater. After a week of adaptation, it can return to seawater and still live normally. It grows best in brackish and freshwater. Generally, it does not migrate long distances.

2. Feeding habits Yellowfin snapper is an omnivorous fish. Benthic algae, benthic crustaceans, floating plants and animals, and organic debris in the water are all suitable baits for it. The larvae mainly feed on animal baits, while the adults mainly feed on plant baits. In early summer, when the water temperature rises to 17℃, the amount of food intake begins to increase, and at 20℃, the feeding activity is most frequent. Generally, the feeding activity is most intense before dusk, and there is little or no feeding in the second half of the night.

3. Growth: The growth rate of yellowfin sea bream in natural waters is: 1-year-old fish is 17.0 cm long and weighs 150 grams; 2-year-old fish is 22.0 cm and 330 grams; 3-year-old fish is 26.0 cm and 560 grams. The largest individual can reach 35.0 cm in length and weigh 3350 grams.

4. Reproduction habits Yellowfin porgy is a hermaphrodite, male-premature fish. The male gonads mature at 1-2 years old, and turn into females at 2-3 years old. The spawning period is early October every year, and it is a one-time batch spawning type. The spawning water temperature is 16-23℃, and the salinity is 25‰-33‰. Yellowfin porgy, also known as red-finned fish, belongs to the family Sparidae of the order Perciformes, and is widely distributed in the Red Sea, the coast of the Arabian Sea, India, Indonesia, Japan, North Korea, the Philippines and the offshore waters of China. It is one of the important economic fish along the coast of South China.
