Embodiment 1

[0033] Prepare a conical bucket with a drain at the bottom, cool the water in the conical bucket to 20°C with ice cubes, put the copepods in the cone-shaped bucket and let it stand for 3 minutes, open the drain at the lower end of the conical bucket, and drain Dead and benthic copepods, and the remaining copepods were used to feed the bearded seabream fry in the nursery pond. The amount of copepods to be fed depends on the amount of seedlings in the nursery pond. It is determined that most of the copepods can be eaten by the bearded sea bream fry in about 4 hours; In a constant temperature and humidity light incubator, adjust the temperature to 27° C. and the relative humidity (RH) to 75%. The larvae can hatch in about 72 hours. The larvae are fed with open feed, and the open feed is composed of the following components according to the mass percentage: 20% corn flour, 18% soybean meal powder, 2% yeast powder, and the balance is water. The total amount of the above mass perce...

Embodiment 2

[0036]Prepare a conical bucket with a drain at the bottom, cool the water in the conical bucket to 18°C ​​with ice cubes, put the copepods in the cone-shaped bucket and let it stand for 5 minutes, open the drain at the lower end of the conical bucket, and drain Dead and benthic copepods, and the remaining copepods were used to feed the bearded seabream fry in the nursery pond. The amount of copepods to be fed depends on the amount of seedlings in the nursery pond. It is determined that most of the copepods can be eaten by the bearded sea bream fry in about 4 hours; In a constant temperature and humidity light incubator, adjust the temperature to 25° C. and the relative humidity (RH) to 80%. The larvae can hatch in about 72 hours. The larvae are fed with open feed, and the open feed is composed of the following components according to the mass percentage: 18% corn flour, 20% soybean meal powder, 1% yeast powder, and the balance is water. The total amount of the above mass perc...

Embodiment 3

[0040] Prepare a conical bucket with a drain at the bottom, cool the water in the conical bucket to 19°C with ice cubes, put the copepods in the cone-shaped bucket and let it stand for 2 minutes, open the drain at the lower end of the conical bucket, and drain Dead and benthic copepods, and the remaining copepods were used to feed the bearded seabream fry in the nursery pond. The amount of copepods to be fed depends on the amount of seedlings in the nursery pond. It is determined that most of the copepods can be eaten by the bearded sea bream fry in about 4 hours; In a constant temperature and humidity light incubator, adjust the temperature to 30° C. and the relative humidity (RH) to 70%. The larvae can hatch in about 72 hours. The larvae are fed with open feed, and the open feed is composed of the following components according to the mass percentage: 22% of corn flour, 15% of soybean meal powder, 3% of yeast powder, and the balance is water. The total amount of the above m...

Abstract

The invention discloses a method for raising seedlings of bearded seabream indoors, comprising the following steps: screening copepod bait, screening black soldier fly larvae bait, making artificial micro fish reefs and putting them in, copepods and black soldier fly larvae of feeding. The invention ensures the supplementation of trace elements of fish fry, improves the immunity of fry, plays a greater role in the survival rate of seedlings at this stage, and simultaneously realizes high-efficiency temporary cultivation in a seedling cultivation room.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for raising seedlings of bearded bream indoors. Background technique [0002] Slant-banded bearded seabream, scientific name Hapalogenys nitens, belongs to the order Perciformes, Perchidae, and the genus Bearded seabream. It is commonly known as iron fish and Baogong fish, and is a coastal bottom-dwelling fish. Its meat is delicious and nutritious, and is very popular among coastal residents in my country. At present, the method of laying eggs in ponds is mostly used in the artificial breeding of bearded sea bream. The eggs of bearded bearded bream obtained by artificial induction are put into the pond, and the natural bait in the pond is used as the bait for the fry. out, put it into the indoor nursery pool to continue fine cultivation. [0003] The nutrient balance requirement of bait is higher in the fry stage of bearded seabream, and specific biolog...
