Artificial induced spawning, fertilization and family establishing method of spotted maigre

A technology for artificial induction and establishment of methods, applied in fish farming, application, climate change adaptation, etc., can solve the problem of not determining the optimal induction period and oxytocin of the parents in detail, unable to form an excellent family of Huanggu system, and not establishing a clear The relationship between the breeding temperature of the oxytocin parent and the oxytocin effect time, etc., can solve the effects of asynchrony of ovulation, high success rate of oxytocin, and large number of eggs produced.

Problems solved by technology

However, this method does not determine the optimal oxytocic period and oxytocic agent for the parents in detail, nor does it establish a clear relationship between the incubation temperature of the oxytocin parent and the time of the oxytocin effect, and it is impossible to form a long-term excellent family of the yellow croaker system

Embodiment

[0018] Embodiment: In late November, the parents of yellow croaker are moved into indoor greenhouses for cultivation. The pool wall and the bottom of the pond are all repaired with cement. The cultivation water depth is 1.5-2.0m, the cultivation density is 10~15 tails / cubic meter, and the water temperature is controlled at 14 Between ~19°C, adjust the feeding amount according to the temperature of the water body. When the water temperature is above 16°C, in the daily feeding, add chilled small miscellaneous fish every 2-3 days, mainly hairtail and small yellow croaker. host. When the water temperature is lower than 16°C, in the daily feeding, add chilled small miscellaneous fish every 3-5 days, and the feeding amount should be controlled at 2-3% of the fish's body weight. There are two oxygen machines to keep the dissolved oxygen in the water sufficient. In mid-March of the following year, the broodstock was transported to the indoor cement pond for cultivation and nutritiona...

Abstract

An artificial induced spawning, fertilization and family establishing method of spotted maigre belongs to the technical field of fish culture. The method comprises the steps of 1, culturing parent fish and enhancing nutrition; 2, selecting the patent fish subjected to induced spawning; 3, selecting odinagogue and dosage; 4, selecting the induced spawning time and the induced spawning temperature; and 5, conducting artificial fertilization and establishing the family. According to the method, based on the gonad development law of the spotted maigre, the optimal induced spawning period of the patent fish and the optimal odinagogue are determined, the relationship between the culture temperature and the induced spawning effect time of the patent fish subjected to induced spawning is established, the success rate of the induced spawning is high, the spawning time is unified, the spawning quantity is high, the spawn supply to the patent fish according to needs is realized.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to a method for artificially induced fertilization and family establishment of yellow croaker. Background technique [0002] Yellow croaker (Nibea albiflora), commonly known as yellow poultry, belongs to the order Perciformes, Scrotoaceae, genus crocodile, offshore middle and lower water fish, and is an important breeding and breeding species in the southeast coast of my country. It has a high Nutritional and medicinal value, the market demand is constantly rising. At present, the reproduction of yellow croaker mostly relies on the natural maturation of the parents to achieve spawning. Due to the difference in the maturity of the parents of croaker, the asynchronous spawning is caused, and artificial control of the spawning time and spawning amount cannot be realized. It is beneficial to production and cannot meet the requirements of fish genetic breeding for directional mat...
