Problems solved by technology

At present, there are few domestic reports on the artificial reproduction of S. chinensis. Only the sexual dimorphism of the morphological characteristics of S. chinensis during the reproductive period and the determination of female adult fertility and the selection of the size of river mussels during spawning and the cultivation of ornamental fish have been reported. Exploring the trial breeding of Selina sinensis in the aquarium, but failed to form a large-scale production

Embodiment 1

[0024] 1. Pond preparation

[0025] (1) Spawning pool

[0026] The spawning pond is an earthen pond with an area of ​​667m 2 , the water depth is 1.3m, and the thickness of the bottom silt does not exceed 10cm. Spray and disinfect the whole pond with 100kg of quickliming slurry, inject water after 10 days, plant Elodea, and use 120kg of biological fertilizer to fertilize the water.

[0027] (2) Incubation pool

[0028] The hatching pool is a circular cement pool with a diameter of 1.2m, which has been sterilized by potassium permanganate in advance, and a circle of nano-microporous pipeline oxygenation equipment is laid on the bottom of the pool, and the water depth is 120cm.

[0029] 2. Selection and breeding of broodstock

[0030] The Chinese bream was caught in Nanyi Lake, Xuancheng City, Anhui Province, and the brood fish were selected as brood fish over 1 year old, with female fish weighing 1.2g-2.0g and male fish weighing 1.5g-4.0g, with good gonad maturity and strong...

[0054] The spawning pond is an earthen pond with an area of ​​1000m 2 , the water depth is 1.5m, the thickness of the bottom silt is 8-9cm, and 150kg of quickliming slurry is splashed and disinfected in the whole pool, water is injected after 7 days, and Elodea and hornwort are planted, every 667m 2 Fertilize water with 120kg biological fertilizer.

[0055] (2) Incubation pool

[0056] The hatching pool is a circular cement pool with a radius of 1.0m, which is sterilized with 2ppm potassium permanganate, and a circle of nano-microporous pipeline oxygenation equipment is laid on the bottom of the pool, and the water depth is 120cm.

[0057] 2. Broodstock selection

[0058] The broodstock should be more than 1 year old, the weight of female fish is 1.2g-2.0g, the weight of male fish is 1.5g-4.0g, the maturity of gonads is good, and the natural waters with strong physique are caught in natural waters. Before stocking, use ...

Abstract

The invention discloses a method for artificial propagation of Selina sinensis, which uses mussels as hosts, puts them in plastic baskets and hangs them around spawning ponds, and puts 1200-1600 mussels in each spawning pond; : 1 pairing, put 1000-1200 pairs of broodstock in each spawning pond; hang the river mussels with fertilized eggs attached to the hatching pond in running water for hatching, and the hatching water temperature is 26-30°C. The present invention simulates the natural breeding process of the Chinese bream in the natural water environment, carries out the artificial breeding of the pond; creates the natural breeding environment of the chinensis in the pond, makes the male and female parents mate naturally in the pond, and improves the survival rate of the parents; selects a suitable production Egg hosts, and rationally adjusting the location and method of host placement, can effectively improve the reproductive efficiency and solve the problem of large-scale breeding of Selina chinensis seedlings.

Description

technical field [0001] The invention relates to an artificial propagation method for scallop chinensis, belonging to the technical field of freshwater fish reproduction. Background technique [0002] Rhodeus sinensis, commonly known as Rhodeus sinensis, is a small bottom-dwelling fish belonging to the family Cyprinidae (Acheilognathinae). It is widely distributed in the Yangtze River, Pearl River, Qiantang River, Minjiang River, etc. in the south of my country. The water system mostly lives in the still water area of ​​lakes and ditches. It is not only a natural bait for large fish and birds, but also has ornamental value. Because of the very special reproductive habits of the bream: in the breeding season, the female fish uses the extended oviposition tube to lay eggs in the gill cavity of the mussel, and the fertilized eggs hatch in the gill cavity of the mussel, and when they develop to the point where they can swim, they can swim. out of the body of mussels, and differen...
