Problems solved by technology

[0003] The natural reproduction method is to carry out natural mating, spawning, and hatching in natural ecological waters. The operation is simple. Because it is more in line with its natural breeding habits, its fertilization rate and hatching rate are better. , The egg production is relatively low, the seedling density and output are low, and the reproductive efficiency is low

Embodiment 1

[0020] A kind of artificial propagation method of artificial ecology in earthen pond of valve knot fish that the present invention proposes, comprises the following steps:

[0021] A. Select the spawning pool: the area of ​​the spawning pool is 2001m 2 , water depth 1.5m, bottom silt <10cm;

[0022] B. Production and placement of fish nests: After covering the surface of the tiles with dense gauze, the tiles are fixed symmetrically to form a hollow elliptical fish nest, and the fish nest is placed in potassium permanganate with a mass fraction of 0.1wt%. Disinfection by soaking in the solution; wooden sticks are arranged in an array of spawning pools, the distance between any wooden stick and the edge of the pool is ≥50cm, two adjacent wooden sticks in each row are connected with ropes, and two adjacent wooden sticks in each row of wooden sticks are connected by rope. The sticks are connected with a rope, and the distance between two adjacent sticks in each row or column is 1...

Abstract

The invention discloses a method for imitating ecological artificial reproduction in an earthen pond of petaled fish, comprising the following steps: A, selecting a spawning pond; B, making and placing a fish nest: after covering the surface of a tile with dense gauze, the tile is symmetrically Fixedly set up a hollow elliptical column fish nest, put the fish nest in potassium permanganate solution for disinfection; wooden sticks are arranged in an array form in the spawning pool, and the distance between any wooden stick and the edge of the pool is ≥ 50cm, and each row of wooden sticks Two adjacent wooden sticks in the sticks are connected with a rope, and two adjacent wooden sticks in each row of wooden sticks are connected with a rope, and the sterilized fish nests are arranged on the rope at intervals and are 8-12cm away from the bottom of the pool; C, parent fish selection; D, Broodstock induction: When the water temperature exceeds 22°C for 7 consecutive days, inject hormones from the base of the pelvic fin: female fish are injected with pituitary hormone 0.013‑0.017 mg / kg, male fish are injected with dioconone and luteinizing hormone releasing hormone analogues, The injection dose is 0.004-0.006mg / kg; E, stocking of broodstock; F, daily management.

Description

technical field [0001] The invention relates to the technical field of artificial propagation, in particular to an artificial ecological artificial propagation method in an earthen pond of a valve knot fish. Background technique [0002] The genus Osteophyta belongs to the class Osteophyta, Cyprinidae, Cyprinidae, Subfamily Cyprinidae, genus Osteophyta, subgenus Osteophyta. Commonly known as: Hasi, Chongkou, Mazui, Laju. The valvefish is a middle-lower fish that lives in clear running water. It has a streamlined body shape, a pointed head, and strong fins. It is one of the fishes that are good at swimming. It often passes through the rocks at the bottom of the water, sucks food from the bottom of the river and the stone surface with its trumpet-shaped flexible mouth, and feeds on benthic molluscs, aquatic insects and their larvae, plant fragments and filamentous algae. Generally, 3-year-old fish reach sexual maturity, and the spawning period is estimated to be between June...
