Abstract

The invention discloses a high-yield cultivation method of carassius auratus gibelio in a coastal saline-alkaline water pond. The method comprises the following steps of (1) constructing the pond, (2) disinfecting the pond, (3) stocking fingerling, (4) feeding bait, (5) regulating and controlling water quality, and (6) preventing and treating diseases. The high-yield cultivation method of the carassius auratus gibelio in the coastal saline-alkaline water pond increases a yield and a survival rate of the carassius auratus gibelio, and improves economic benefits.

Description

technical field [0001] The invention relates to a freshwater fish culture method, in particular to a high-yield culture method for heterogeneous gibel crucian carp in coastal saline water ponds. Background technique [0002] Allogynogenetic crucian carp (Allogynogenetic crucian carp) is a new breeding object for crucian carp successfully developed by fish breeding experts from the Institute of Hydrobiology, Chinese Academy of Sciences from 1976 to 1981. , with Xingguo red carp as the male parent, the offspring bred by artificial insemination. The traits of the offspring are not separated, which is very beneficial to the subculture and expanded production of heterogeneous gibel carp seedlings. The growth rate of heterogeneous gibel carp is 34.7% faster than that of the male parent, and 2-3 times faster than that of common crucian carp. Generally, the seedlings of the same year can grow to 200-250g. This species is suitable for ponds in saline-alkali coastal tidal flats. The...
