Problems solved by technology

[0004] At present, the pufferfish seen in the market is mainly caught artificially. The meat is fresh and delicious, with high nutritional value. The artificial breeding technology in indoor cement pools is still immature, and the survival rate of outdoor breeding of pufferfish is low, and the gill filaments are easily eroded, resulting in incomplete gill filaments or silt, resulting in insufficient blood supply in the body and intolerance to hypoxia. The survival rate of spiny puffer indoor seedlings in summer is only 3-8%.

Embodiment 1

[0033] A method for artificially raising seedlings in an indoor cement pond of pufferfish, comprising the following steps:

[0034] S1. Nursery pool preparation

[0035] The volume of the indoor nursery pool is 6.0m×6.0m×1.5m, with 2 diagonal water inlets and 1 central drain. 7 days before the newly hatched larvae enter the pond, check the drainage and oxygenation equipment of the nursery pond, and disinfect the nursery pond. 3 days before the seedlings are released, after entering 60cm of water, use algae liquid and probiotics to fertilize the water, and wait until the water color is light green or yellow-green, and the transparency is 30cm, then the seedlings can be released.

[0036] S2. Newly hatched larvae enter the pond

[0037] Under the conditions of water temperature of 26.0°C and salinity of 30.0 in summer, the fertilized eggs hatched for 100 hours, and the total length of the newly hatched larvae was about 3.3mm. Artificially hatched newly hatched larvae are calc...

Embodiment 2

[0049] A method for artificially raising seedlings in an indoor cement pond of pufferfish, comprising the following steps:

[0050] S1. Nursery pool preparation

[0051] The volume of the indoor nursery pool is 6.0m×6.0m×1.5m, with 2 diagonal water inlets and 1 central drain. 7 days before the newly hatched larvae enter the pond, check the drainage and oxygenation equipment of the nursery pond, and disinfect the nursery pond. 5 days before the seedlings are released, after entering 60cm of water, use algae liquid and probiotics to fertilize the water, and wait until the water color is light green or yellow-green, and the transparency is 40cm, then the seedlings can be released.

[0052] S2. Newly hatched larvae enter the pond

[0053] Under the conditions of water temperature 27.0℃ and salinity 32.0 in summer, fertilized eggs hatched for 140 hours, and the total length of newly hatched larvae was about 3.3mm. 3 The density of seedlings.

Embodiment 3

[0065] A method for artificially raising seedlings in an indoor cement pond of pufferfish, comprising the following steps:

[0066] S1. Nursery pool preparation

[0067] The volume of the indoor nursery pool is 6.0m×6.0m×1.5m, with 2 diagonal water inlets and 1 central drain. 7 days before the newly hatched larvae enter the pond, check the drainage and oxygenation equipment of the nursery pond, and disinfect the nursery pond. 3-5 days before the seedlings are placed, after entering 60cm of water, use algae liquid and probiotics to fertilize the water. When the water color is light green or yellow-green, and the transparency is 30-40cm, the seedlings can be released.

[0068] S2. Newly hatched larvae enter the pond

[0069] Under the conditions of water temperature of 26°C and salinity of 31.0 in summer, the fertilized eggs hatched out of the membrane after 120 hours, and the total length of the newly hatched larvae was about 3.3mm. Artificially hatched newly hatched larvae ...

Abstract

The invention provides an indoor cement pond artificial fry breeding method for porcupine pufferfish. The method comprises the following steps: fry breeding pond preparation, newly hatched fry pond entry, bait feeding strategy in fry breeding period, water quality management in the fry breeding period, fry pond division, fry emergence and the like. Compared with the prior art, the method has the advantages that the water quality and environmental conditions of a nursery pond are strictly controlled, and scientific and reasonable feeding and operation management are performed in different fry breeding stages according to the biological characteristics and nutritional requirements of the porcupine pufferfish, so that large-scale production of artificial fry breeding of the porcupine pufferfish is realized.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for artificially raising seedlings in indoor cement ponds of pufferfish. Background technique [0002] Chinese name: Porcupine pufferfish; English name: Porcupine pufferfish; Latin scientific name: Diodon hystrix. The dense-spotted pufferfish belongs to the class of ray-finned fishes, the order of pufferiformes, and the family of pufferidae. 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...
