Problems solved by technology

[0003] The existing artificial breeding technology for red sea bass is in its infancy. In the artificial fry process of red sea bass, there are problems of low survival rate of larvae and juveniles and high deformity rate.
In the early development stage before the age of 30 days, the larvae have poor adaptability to bait switching and low food intake, and are prone to slow growth and deformity of the larvae; especially the larvae before the age of 7 days are weak in active feeding ability, and they are prone to larvae due to early Death due to malnutrition greatly affects the survival rate and emergence rate of artificial seedlings of red sea bass
Therefore, it is difficult to realize the large-scale production of the seed of effective red sea bass at present, and the phenomenon that seed lacks occurs in the factory culture of red sea bass

Embodiment 1

[0032] The outdoor ecological pond artificial breeding method of embodiment 1-a kind of efficient red nine perch, comprises the steps:

[0033] (1) Pre-treatment of cultivation environment:

[0034] Select an outdoor pond with a water level depth of 1.5m. After removing the sundries at the bottom of the pond and disinfecting it, dry the pond continuously for 7 days, inject filtered and sterilized seawater, and evenly sprinkle bio-organic fertilizer 16kg / m on the pond. 3 ; and one week before the newly hatched larvae enter the pond, add 0.02mg / L of complex bacteria every day, and Nannochloropsis and Spirulina with a mass ratio of 1:3, and the water body will maintain a transparency of 35-42cm;

[0035] (2) stocking in ponds:

[0036] The newly hatched larvae were placed at a density of 6000 fish / m 3 Put it into the pool, the temperature of the water in the pool is 25°C, the salinity of the pool is 29, and the pH value is 7.6;

[0037] (3) Feeding management before 7 days of ...

Embodiment 2

[0048] Embodiment 2-a kind of outdoor ecological pond artificial seedling raising method of efficient red nine perch, comprises the steps:

[0049] (1) Pre-treatment of cultivation environment:

[0050] Select an outdoor pond with a water level depth of 2.5m. After removing the debris at the bottom of the pond and disinfecting it, dry the pond continuously for 10 days, inject filtered and sterilized seawater, and evenly sprinkle 20kg / m of bio-organic fertilizer on the pond 3 ; And one week before the newly hatched larvae enter the pond, add 0.03mg / L of complex bacteria every day, and Nannochloropsis and Spirulina with a mass ratio of 1:5, and the water body will maintain a transparency of 35-42cm;

[0051] (2) stocking in ponds:

[0052] The newly hatched larvae were placed at a density of 10,000 fish / m 3 Put it into the pool, the water temperature in the pool is 27°C, the salinity in the pool is 32, and the pH value is 8.4;

[0053] (3) Feeding management before 7 days of ...

Embodiment 3

[0062] Embodiment 3-a kind of outdoor ecological pond artificial seedling raising method of efficient red nine perch, comprises the steps:

[0063] (1) Pre-treatment of cultivation environment:

[0064] Select an outdoor pond with a water level depth of 1.8m, remove the debris at the bottom of the pond and disinfect it, then dry the pond continuously for 9 days, inject filtered and sterilized seawater, and evenly sprinkle bio-organic fertilizer 18kg / m on the pond 3 ; and one week before the newly hatched larvae enter the pond, add 0.025mg / L of complex bacteria every day, and Nannochloropsis and Spirulina with a mass ratio of 1:4, and the water body will maintain a transparency of 35-42cm;

[0065] (2) stocking in ponds:

Abstract

The present invention provides an efficient method for artificial breeding of red sea bass in an outdoor ecological pond, comprising the following steps: (1) pre-treatment of the cultivation environment, (2) stocking in the pond, (3) feeding management before 7 days of age, larvae 3-5 days old, feed rotifers and euglena slender daily; larvae 4-7 days old, feed enhanced powder bait daily; enhanced powder bait includes papaya powder, green orange powder, yeast powder and active lactic acid bacteria rotifers and artemia nauplii for larvae at 6 to 7 days old; (4) feeding management after 7 days of age, when larvae were 10 days old and 20 days old, they were fed continuously for 3 Transitional bait for ~4 days; (5) water quality regulation; the present invention effectively improves the active feeding ability of larvae before 7 days of age, and effectively promotes larvae to better adapt to the replacement of bait, and improves the nutritional balance and growth balance of individual larvae. Reduce the deformity rate, improve the survival rate and growth quality of fry.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an efficient artificial seedling raising method for red sea bass in an outdoor ecological pond. Background technique [0002] Cephalopholis sonnerati (Cephalopholis sonnerati), commonly known as reticulated carp, cross fish, grouper, red rudder, red melon seed spot, is a fish belonging to the genus Cephalopholis sonnerati of the ray-finned fishes Perciformes suborder Percisidae . The body is red, with dark brown reticulation on the head and front of the back, without spots and stripes. There are no canines in the middle of the lower jaw, and the anal fin has 3 spines and 9 rays. Caudal fin rounded, without stripes. As a high-grade edible fish on the existing market, red sea bass is very popular among consumers. [0003] The existing artificial breeding technology for the red sea bass is in its infancy. In the artificial fry process of the red sea bass, there are problems ...
