In 1993, the fish was introduced into China for the first time and was listed by the State Bureau of Foreign Experts Affairs and the Ministry of Agriculture as the key scientific research and promotion projects for the “Ninth Five-Year Planâ€. In 1996, the first time in the country, oyster production was promoted and hundreds of thousands of oysters were obtained.
First, the fish has the following good characteristics:
(I) The meat is delicious. The protein content of the fish is 17.99-18.03%, which is higher than that of Qing (15.8%), grass (15.5%), calyx (15.3%), carp (14.0%), Helan (15.43%) , Channel fork (16.3%), Leather beard (15.58%), and Astragalus (14.9%). The total content of four kinds of umami amino acids such as glutamic acid, aspartic acid, glycine, and alanine was 6.7%, which was higher than that of punctal tail (6.36%), carp (5.35%), and stingray ( 5.3%), Egyptian leather beard (5.52%). The fish's 18 amino acid content (without tryptophan and methionine) was 16.84%, slightly higher than that of salmon (16.67%). Tasted by fisheries experts from Guangdong Provincial Fisheries Department and Gaoyao City, Guangdong Province, said that “the meat is particularly refreshing and refreshing, and the taste is different from that of squidâ€.
(b) Large individuals, fast growth, and high yields. The maximum weight found in the United States in Iowa can reach 80 pounds (36.3 kg). In the United States of origin, up to 500 grams of 1st instar fish, 2 instar 800-1500 grams, 3 instar 2000 grams. In China's Central China region, fish can reach 135-605 grams at the end of the year, 700-1500 grams in the second year, and 1500-2500 grams in the third year.
The fish is raised in a single pond, yielding 399.8-513.1 kg per mu and 35-82.8 kg per mu.
(C) suitable temperature and wide, suitable salt wide, low oxygen consumption. The survival temperature of the fish is 0-41.4°C. It can grow in a 2.1-17.2% semi-saline environment. The average body length is 6.9cm. The oxygen consumption rate of American bigmouth bass, which weighs 7.6g, is 0.164mg/g.hr. The asphyxiation point of the American bigmouth bass at an average temperature of 1.115mg/half hr and a mean body length of 6.9-10cm at a water temperature of 30.6-32.1°C is 0.30000-0.3500 mg/L, which is lower than that of Qing (0.5800) and Qi (0.7900).鲶 (0.9470-1.5510mmg/L).
(d) foodstuffs are easy to solve. At the stage of larvae, the American bigmouth bass was mainly fed with phytoplankton. In the stage of 2-6cm, zooplankton was mainly consumed. After 7cm, zooplankton and zoobenthos were ingested. Artificial diet conditions like eating a variety of cakes and so on. Artificially formulated large-mouth rouge made from animal feed, cakes, etc. is also very much like to eat.
(e) Mature and spawning. The fish males are second-aged and the females reach sexual maturity when they reach the third instar. A 66.5cm long female can lay 750,000 eggs.
Second, the fry to cultivate the American bigmouth roach fish breeding can be used nursery, cement pools, cages, ponds for cultivation.
Breeding device: The nursery device is round, 94cm in diameter, 14cm in height, and 0.3 cubic meters in volume. The fry is kept in its interior for 6 days. The size can reach 0.71-0.83cm. After 12 days of feeding, the specification can be 1.1-1.4cm.
Cement pond cultivation: The cement pool area should not be too large, 0.5-2 cubic meters can be, each pond can put 0.5-0.7cm fry 3000-4000 tail. The cement pool maintains micro-flowing water day and night, exchanged once every 48 hours. The fry is cultivated in the cement pool for 12-14 days. The specification can be 2.5-3.2cm and the survival rate is 93-97%.
Cultivation of cages: cages with a height and width of 1.510.8 meters, the upper corners of the cages are fixed on bamboo frame floats, and the bottom corners of the cages are tied with stones to keep the cages in a good state of expansion and contraction. About days of cultivation, specifications up to 3.0-3.4cm, survival rate of 96.5-98.8%.
Pond cultivation: an area of ​​1-2 mu is appropriate, less silt at the bottom of the pool, convenient drainage, water storage capacity of 0.8 meters or more, thoroughly clearing the pond with quicklime before putting the seedlings, and training after 10 days according to Chinese traditional method of cultivating fry Fertilizer quality, a large number of floating organisms to be placed in fry. The fry is cultivated for 20-25 days, and the survival rate of the specification reaches 3.5-5cm of 84.5-91.7%.
Third, the cultivation of fingerlings The cultivation of large-mouth American fish is based on cement pond cultivation and pond cultivation.
Cement pond cultivation: cement pool area of ​​1-10 cubic meters can be, with inlet and outlet. Shape can be square, round, structure is overflow. The fish mu is cultivated for 30 days, from 4-5 grams of weight gain to 8.1-13 grams, and the survival rate is 95-100%.
Pond cultivation: 1-2 hectares of ponds are mainly used in foreign countries, and we have cultivated ponds with 2-4 acres of ponds. The pond is 1.5 meters deep and 1.2 meters deep. Before the ponds were placed, the ponds were sterilized and fertilized according to the pond cultivation method mentioned above. The fry were set at 3-4 cm per mu for 300-4000 fry. The fry were cultivated for about one month and the average size was about 60 g (50-110 in amplitude). g), the survival rate can reach 90-98%, and it can be raised from February to March, with an average of more than 150 grams.
