Ecology-simulated artificial tor (foliter) brevifilis brevifilis breeding method by virtue of earthen pond

Abstract

The invention discloses an ecology-simulated artificial tor (foliter) brevifilis brevifilis breeding method by virtue of a earthen pond. The ecology-simulated artificial tor (foliter) brevifilis brevifilis breeding method comprises the following steps: A. selecting a spawning pond; B. construction and placement of fish spawning nests: covering the surfaces of tiles with dense gauze, symmetrically and fixedly arranging the tiles to define a hollow elliptical columnar fish spawning nests, and soaking and disinfecting the fish nests with potassium permanganate solution; distributing wood sticks into the fish spawning pool in an array manner, wherein the distance between any one wood stick and the bank of the pool is more than or equal to 50cm, every two wood sticks in each row of wood sticks are connected with a rope, every two wood sticks in each column of wood sticks are connected with a rope, and the disinfected fish spawning nests are arranged on the rope at intervals and have a distance of 8-12cm away from a pond bottom; C. selecting parent fishes; and D. spawning induction of parent fishes: when the temperature continuously exceeds 22DEG C for 7 days, performing hormone injection from the pelvic fin base part of each parent fish: injecting 0.013-0.017mg / kg of pituitary hormone for each female fish and injecting 0.004-0.006mg / kg of domperidone and luteinizing-hormone releasing hormone analog for each male fish; E. releasing parent fishes; and F. performing 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...

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
