Problems solved by technology

Applying the breeding technology of American shad to Indian shad farming will encounter many technical challenges in practice, especially in the breeding process of technical parameters and management measures of water temperature, light, water quality and other breeding environmental factors. There is a large uncertainty, so there is a relatively large blindness in Indian shad farming at present, and the success rate is low

Embodiment 1

[0053] Example 1 Cultivation mode of Indian shad pond-greenhouse collocation

[0054] A method for cultivating Indian shad, comprising the following steps:

[0055] (1) Venue selection:

[0056] The Indian shad culture pond covers an area of ​​0.5 to 20 mu and has a water depth of 1.2 to 4.0 m. In Guangdong and other regions, overwintering ponds need to use plastic film greenhouses. The greenhouse area is 1-10 mu, the width is 10-100m, and the water depth is 1.0-3.0m.

[0057] (2) Three-stage cultivation and breeding

[0058] According to the biological characteristics and seasonal adaptation characteristics of Indian shad at each developmental stage, in order to improve the survival rate of culture, pond culture can be divided into three stages, namely fingerling cultivation, overwintering cultivation and adult fish cultivation.

[0059] Fingerling cultivation: In spring, when the water temperature is 20-35°C, Indian shad seedlings (3-5cm) are stocked in outdoor ponds for ...

Embodiment 2

[0068] Example 2 Cultivation of Indian shad in greenhouse mode

[0069] A method for cultivating Indian shad, comprising the following steps:

[0070] (1) Venue selection:

[0071] Greenhouse culture of Indian shad is suitable for areas such as Jiangsu, Zhejiang and Shanghai. It adopts a greenhouse with good thermal insulation, and the fish pond area is 50-300M. 2 And the water depth is 1.0-2.5M.

[0072] (2) Three-stage greenhouse cultivation and breeding

[0073] Greenhouse farming can be divided into three stages, namely fingerling cultivation, overwintering cultivation and adult fish cultivation.

[0074] Fingerling cultivation: When the water temperature is 20-35°C, the Indian shad seedlings (3-5cm) are stocked in the greenhouse for fingerling cultivation. The greenhouse is a shade greenhouse, the shade area is more than 90%, and the light intensity is 500-1000lux. Fish finger pond area is 20 ~ 200m 2 , stocking density 10~50 tails / m 2 , the water depth is 1.2 ~ 2....

Abstract

The invention discloses a method for breeding hilsa. According to the method for breeding the hilsa, breeding conditions suitable for growth and development of the hilsa are created, and the method comprise the specific steps that the breeding temperature is adjusted to range from 12 DEG C to 38 DEG C, and / or the illumination intensity is adjusted to range from 100 lux to 1000 lux, and / or the breeding density is adjusted to range from 1-50 per square meter. According to the method for breeding the hilsa, the breeding difficulty that currently at home and abroad, the hilsais low in breeding survival rate, high in overwintering death rate and low in growth speed is solved; according to the technical scheme, according to the biological characteristics of the hilsa, the ecological key factor range, technical measures and breeding management schemes suitable for growth and development of the hilsa are provided, a breeding environment and a breeding process suitable for growth and development of the hilsa are set up, the growth speed and the survival rate of the hilsa are increased, and development of the hilsa breeding industry is promoted.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for culturing Indian shad. Background technique [0002] Chinese shad was once unique and one of the most valuable economic fish in my country. Since the 1970s, due to overfishing, environmental degradation and habitat destruction, the resources of Chinese shad have been declining, and by the end of the 1980s, no trace of Chinese shad has been seen; Alternative species of shad have been introduced into China, and a certain breeding scale has been formed in China, and a variety of shad farming techniques have been successfully applied. Since Indian shad and Chinese shad belong to the same genus and are more similar, they have also been introduced to China in recent years. At present, the breeding technology of Indian shad is in the research and development stage. [0003] Tenualosa ilisha, also known as Bengal shad, is a warm-water fish widely distributed in the low...
