Problems solved by technology

[0004] Anchovy is a reproductive migratory fish. It is difficult to break through artificial reproduction, and the seedlings only come from natural seedlings. In addition, the anchovy is very delicate and dies when it is out of water.
In recent years, there have also been reports of the cultivation of cuttlefish in the seine "Jiangxinzhou", but this technology has disadvantages such as limited breeding areas and difficult environment control.

Embodiment 1

[0037] Embodiment 1: the pond ecological cultivation method of a kind of cuttlefish of the present invention irrigates river accepting seedling, adopts following cultivation steps:

[0038] Location: Base of Yangtze River Rare Fish Conservation Research Center

[0039] (1) earth pond selection

[0040] The area of ​​the riverside earth pond and Namiao pond is 5 mu, the depth of the pond is 1.5m, and the bottom mud is 5cm. On May 7, the pond was disinfected and exposed to the sun for 6 days through 120Kg / mu quicklime clear pond.

[0041] (2) Set up a dedicated seedling area

[0042] Before the pond is released, a 40-mesh silk screen is used to divide the pond near the water inlet into a seedling area that accounts for about 1 / 4 of the total area of ​​the pond. The upper part is fixed on both sides of the pond with ropes. The bottom is fixed with a gabion to prevent escape. The water inlet is covered with a bag-shaped knotless net with a net mesh of 0.8cm to prevent relative...

Embodiment 2

[0055] Embodiment 2: the pond ecological cultivation method of a kind of cuttlefish irrigation Jiang Namiao of the present invention adopts following cultivation steps:

[0056] Location: Jiangyin Shengang Sanxian Breeding Co., Ltd.

[0057] (1) earth pond selection

[0058] The area of ​​the riverside earth pond and Nanmiao pond is 4 mu / mouth, the water depth of the pond is 1.8m, and the bottom mud is 8cm. On May 7, the pond was disinfected and exposed to the sun for 10 days through 120Kg / mu quicklime clear pond.

[0059] (2) Set up a dedicated seedling area

[0060] Before the pond is released, a 40-mesh silk screen is used at the end of the pond near the water inlet to divide it into a seedling area that accounts for about 1 / 4 of the total area of ​​the pond. The upper part is fixed on both sides of the pond with ropes. The mesh is 18cm above the water surface. The bottom is fixed with a gabion to prevent escape. The water inlet is covered with a bag-shaped knotless net...

Embodiment 3

[0073] Embodiment 3: the pond ecological cultivation method of a kind of cuttlefish irrigation Jiang Namiao of the present invention adopts following cultivation steps:

[0074] Location: Jiangyin Fisheries Guidance Station Base

[0075] (1) earth pond selection

[0076] The area of ​​the riverside earth pond and seedling pond is 4 mu / mouth, the water depth of the pond is 2.0m, and the bottom mud is 10cm. On May 25, the pond was disinfected and exposed to the sun with 120Kg / mu of quicklime clear pond, and 30Kg / mu of organic fertilizer was applied 15 days later for fertilizer and water.

[0077] (2) Set up a dedicated seedling area

[0078] Before the pond is released, a 40-mesh silk screen is used to divide the pond near the water inlet into a seedling area that accounts for about 1 / 4 of the total area of ​​the pond. The upper part is fixed on both sides of the pond with ropes. The mesh is 20cm above the water surface. The bottom is fixed with a gabion to prevent escape. T...

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...
