Study on the Key Techniques and Effects of Mono-culture Acrossocheilius Hemispinus in Earthen Ponds

In order to explore the artificial culture technology of Acrossocheilius hemispinus, the experiment of mono-culture Acrossocheilius hemispinus in earthen ponds was carried out in Pond No.4 (having an area of 1 150 m²) in Area C of the larval rearing cooperative base of Fujian Institute of Freshwater Product Research. The results showed that when the total length of the fish reached more than 12 cm in the earthen pond, the fish could all be caught and put on the market in the dry ponds. The whole breeding test cycle was about 12 months, and the comprehensive feed coefficient was about 1.43. The total production of marketable fish harvested in the experiment was 1 109.95 kg, among which the total production of Acrossocheilius hemispinus was 343.65 kg, with an average yield of 199.8 kg per 667 m², and the survival rate was about 67.3%. The total output value of the cultivation experiment was 29 532 yuan, among which the output value of Acrossocheilius hemispinus was 20 619 yuan, accounting for 69.8% of the total output value, with an average output value of 11 987 yuan per 667 m². The total profit of the cultivation was 7 576 yuan, and the average profit was about 4 405 yuan per 667 m².
