Abstract

The invention relates to a pool ecological breeding method for coilia nasus by filling river water to accept fries, and belongs to the technical field of fry accepting and breeding. The method is characterized by comprising the following process steps: (1) selecting a soil pool along the river; (2) using a silk cover net to set a special fry accepting area; (3) when the fry amount reaches 1 to 3 fish per liter, adopting a water pump to accept the fries in time; (4) adopting the measures of pouring soybean milk and throwing ovigerous shrimps by a netlike box to breed natural food organisms; (5) when the temperature of water in the pool is below 10 DEG C, carrying out separation and wild removal operations for advanced fry in the fry accepting pool; (6) adopting the ecological technical measures such as throwing fermented organic fertilizer, stocking juvenile shrimps, breeding silver carp and the like to strictly adjust and control water quality and breed the coilia nasus in a special pool; and (7) breeding the coilia nasus to a period of two winters, and fishing the coilia nasus to sell according to the market demand. The method effectively breaks through the pool breeding problem of the coilia nasus, obtains the coilia nasus which has the same quality as wild coilia nasus, further achieves artificial breeding of the coilia nasus on a deeper level, builds a good ecological environment, and can remarkably improve the survival rate of the fries.

Description

technical field

[0001] The invention relates to a pond ecological culture method for irrigated river anchovy and seedlings, and belongs to the technical field of fish seedling storage and cultivation. Background technique

[0002] Coilia nasus, scientific name Coilia nasus, also known as long-jawed anchovy, commonly known as hairy fish, shaving fish, hairy fish, and swordfish, belongs to the genus Anchovy in the order Anchovy in the order Herringiformes. Known for its tender meat and delicious taste, it is a rare fish that enjoys the reputation of one of the "three delicacies of the Yangtze River". In recent years, due to the influence of many factors such as overfishing and ecological deterioration, the resources of cuttlefish have declined sharply. Difficult, but urgently needed to be resolved. Therefore, it is of great significance to break through the artificial domestication and breeding of the sword anchovy, and then carry out the artificial breeding and multiplicati...
