The blue-fish (Lepomis macrochirus L.) is a species of sunfish of the family Gypicoidea. The fish is native to North America and is distributed from Ontario, Canada, the Great Lakes system in southern Quebec, and rivers, lakes, and other waters in various states in the southern United States and northern Mexico. The fish are small in size and are often 50-100 g per tail. The big ones are about 2kg/tail. From the point of view of morphology, the blue pelagic sunfish resembles Nile tilapia somewhat. The most striking feature of the appearance is that the larvae have a black, ear-like soft membrane at the trailing edge, which is a common feature of all sunfish. Just different kinds of "eardrum" have different colors and different forms only. The blue-bellied sunfish's head to the abdomen is pale orange-red or light-orange-yellow, with a pale blue-gray back, with some grayish-black vertical lines, but it is less obvious. Head high back, rich in meat. From March to October each year, it is the breeding season of the blue snapper sunfish. The male body at this time looks particularly dazzling and beautiful. In general, a female 15 cm long can lay 65,000 eggs and spawn several times. The fish is suitable for a wide range of temperature and can normally feed at low water temperatures (12 degrees C). Blue-bellied sunfish are mainly animal-based. Under artificial rearing conditions, feeding artificially-combined pellet feed can also fully meet its growth needs. The protein content of feed can be 32-362/0. The fish is very adaptable, and both large and small water bodies can grow. The breeding method is based on monoculture of intensive culture ponds. The pond area is 3 to 5 mu and the water depth is 1.5 to 2 meters. It is advisable to stock 3 to 4 centimeters per acre and fry between 1,000 and 12,000. Feeding palatable granules, the daily dosage accounts for about 100/0 of the fish's body weight, and when it grows to about 100 grams/tail, the daily dosage accounts for 70/0 of the fish's body weight, depending on weather conditions and feeding conditions. During the breeding process, the fish rarely develops, but the prevention and treatment of fish diseases must still be emphasized. The control methods are similar to those of other freshwater fishes. The blue-eyed sunfish is a very good fish. Although the individual is small, its meat is extremely delicious, which is unmatched by many famous fish. The Blue Stork Sunfish is a rare fish that is a combination of ornamentals, cuds, and food. It is currently an emerging breed.
