The blue-spotted sunfish (Lepomis macrochirus L.) is a species of the genus Sunfish of the family Paleomorpha. The fish is native to North America, from Ontario, Canada, southern Quebec to the Great Lakes, USA, and the entire United States.
There are distributions in rivers, lakes and other waters in various states and northern Mexico. The individual fishes are relatively small, the common ones are mostly 50-100 g/tail, and the larger ones are about 2 kg/tail. From the point of view, the size of the blue scorpion fish is somewhat similar to that of Nepal.
The most noticeable feature of the tilapia is the black membrane in the form of a soft, ear-like soft film at the trailing edge of the lid. It is a common feature of all sunfish, except that different species of the eardrum have different colors and shapes. . Blue Dragonfly
Sunfish are pale orange or light orange in color from the head to the abdomen. The back is light gray with some grayish-black vertical stripes, but it is less obvious. Head high back, rich meat.
From March to October each year, it is the breeding season of the blue pelicans sunfish. The male body at this time looks particularly dazzling and beautiful. In general, a female 15 cm long can spawn between 12,000 and 65,000 eggs and is spawning several times. by
Since the fish has a long breeding season, there are a large number of seedlings available for planting from the spring to the beginning of winter. The fish is suitable for a wide temperature range and can normally feed and grow at low water temperatures (12°C).
Blue-bellied sunfish are mainly eaten with animal feed. In artificial rearing conditions, feeding artificially-combined pellet feed can also fully meet its growth needs. The protein content of feed can be 32-36%.
The fish is very adaptable, and both large and small water bodies can grow. The breeding method is to use a single intensive cultivation of ponds. The pond area is 3-5 mu and the water depth is 1.5-2 meters. It is appropriate to stock 3-4 centimeters per fish per acre.
- 1200 tails. Feeding palatable granules, the daily dosage accounts for about 10% of the fish's body weight, and when it grows to about 100 grams/tail, the daily dosage accounts for 7% of the fish's body weight, depending on the weather and feeding conditions. During the breeding process, the fish rarely develops, but the prevention and treatment of fish diseases is still important. The control methods are similar to those of other freshwater fishes.
Blue-eyed sunfish are spawning fish many times, so females grow slowly. After being introduced from abroad, this problem has been encountered during the promotion of aquaculture, which has had a negative impact on the promotion of this fish. In fact, the blue ray sun fish is
A very good fish, although the individual is small, but its meat is extremely delicious, is not comparable to many famous fish. In order to solve the problem of slow growth of females in the long breeding season, fish breeding experts in the United States have recently developed a new technology called “sexual transformation†to convert females that have been hatched into adult male fry after sexual conversion. With this fry stocking, generally raised 6-8 months, the average weight can reach 400-500 g / tail, which greatly improves the economic benefits. Since the blue snapper is a food fish and an ornamental fish, it has both economic value and ornamental value. At present, commercial fish with 100 g/head or more are very popular with consumers. The price is good and demand exceeds supply. Therefore, grasping the opportunity to properly develop its cultivation in a timely manner is another opportunity for wise breeders to get rich.
