Embodiment 1

[0039] A kind of artificial breeding method of pufferfish, comprises the following steps:

[0040] S1. Source and screening of broodstock:

[0041] The broodfish of puffer pufferii were captured in natural sea areas and obtained through artificial domestication. The puffer pufferfish over 3 years old, with a weight of 1.0-1.5kg, normal body shape, no injury, no disease, and good vitality were selected as parents.

[0042] S2. Intensive breeding of broodstock:

[0043] Breeding density: The volume of the indoor broodstock breeding pond is 6.0m×6.0m×1.5m, with 2 diagonal water inlets and 1 outlet, the breeding density is 80 fish / pond, and the ratio of male to female is 1:0.5;

[0044] Water quality management: Regularly detect temperature, salinity, dissolved oxygen, pH value, oxygenation power, ammonia nitrogen, and nitroso nitrogen every day, and keep the water quality indicators of the cultivation water in line with the requirements of the cultivation conditions. According t...

Embodiment 2

[0065] A kind of artificial breeding method of pufferfish, comprises the following steps:

[0066] S1. Source and screening of broodstock: Broodstock are purchased from fishermen in subtropical waters, and individuals who are healthy, disease-free and trauma-free are screened.

[0067] S2. Intensive breeding of broodstock:

[0068] Breeding density: The volume of the indoor broodstock breeding pond is 6.0m×6.0m×1.5m, with 2 diagonal water inlets and 1 outlet, the breeding density is 100 fish / pond, and the ratio of male to female is 1:1;

[0069] Water quality management: Regularly detect temperature, salinity, dissolved oxygen, pH value, oxygenation power, ammonia nitrogen, and nitroso nitrogen every day, and keep the water quality indicators of the cultivation water in line with the requirements of the cultivation conditions. According to the change of water quality, change every 3 to 5 days For one water change, the amount of water change is 50%, and the transparency of the...

[0090] A kind of artificial breeding method of pufferfish, comprises the following steps:

[0091] S1. Source and screening of broodstock: Broodstock are purchased from fishermen in subtropical waters, and individuals who are healthy, disease-free and trauma-free are screened.

[0092] S2. Intensive breeding of broodstock:

[0093] Breeding density: The volume of the indoor broodstock breeding pond is 6.0m×6.0m×1.5m, with 2 diagonal water inlets and 1 outlet, the breeding density is 80-100 fish / pond, and the ratio of male to female is 1:0.8;

[0094] Water quality management: Regularly detect temperature, salinity, dissolved oxygen, pH value, oxygenation power, ammonia nitrogen, and nitroso nitrogen every day, and keep the water quality indicators of the cultivation water in line with the requirements of the cultivation conditions. According to the change of water quality, change every 3 to 5 days For one water change, the amount of water change is 40%, and the transparency o...

Abstract

The invention provides an artificial breeding method of diodon hystrix. The artificial breeding method comprises the following steps of: parent fish sourcing and screening, intensive parent fish breeding, parent fish spawning induction and artificial breeding. According to the artificial breeding method, diodon hystrix parents are enriched in bait nutrition, and the parents can be matured in gonaddevelopment under the artificial breeding condition through coordination of technological conditions of temperature, salinity, dissolved oxygen, pH value, oxygenation power, ammonia nitrogen and nitroso nitrogen, so that the hatchability of the parents is high through artificial spawning induction and hatching. The fry hatched by adopting the method grows fast, balanced in nutrition, strong in immunity, high in meat content and high in survival rate, and the method can be used for large-scale breeding of diodon hystrix fry and meets the requirement of large-scale breeding. Moreover, through three-stage artificial fry breeding, the delicious taste of wild diodon hystrix is kept, the bred diodon hystrix has special quality, flavor and rich nutrition, and the economic benefit and the ecological benefit are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of aquatic cultivation, in particular to an artificial breeding method of pufferfish. Background technique [0002] Chinese name: Porcupine pufferfish; English name: Porcupine pufferfish; Latin scientific name: Diodon hystrix. Diodon hystrix (Diodon hystrix) is a species of ray-finned fishes, Fuguiformes, Diodonidae. Distributed in subtropical waters of the world's oceans. The type locality of this species is India. When attacked, it will inhale sea water to swell its body into a ball, and erect spines to prevent the enemy from swallowing. Carnivorous, mainly feeds on benthic animals, poisonous. The dense-spotted spinyfish can reach a length of 91 centimeters. The body is short and wide, the mouth is small, and the upper and lower jaws in the mouth each have a well-developed tooth plate. Except the lip and caudal peduncle are densely covered with strong spines specialized by scales. The spines are sho...
