GB/T 34732-2017 in English

In-depth interpretation of the National Standard of the People's Republic of China GB/T 34732—2017 Technical Specifications for Artificial Propagation of Songjiang Perch

Background of Standard Formulation and Analysis of Technical Evolution

As an important economic fish, Songjiang perch occupies an important position in my country's aquaculture industry. However, due to its limited natural reproductive capacity, the standardization of artificial breeding technology is particularly important. The formulation of this standard is based on long-term scientific research accumulation and practical experience, aiming to standardize the artificial breeding process of Songjiang perch and improve aquaculture efficiency and quality.

Technical Specifications for Broodstock Breeding

Key points of artificial breeding technology

Artificial breeding is a key link in the breeding of Songjiang perch, which mainly includes spawning pond preparation, oxytocin injection and natural spawning process.

Fish fry cultivation and management recommendations

During the fry cultivation stage, special attention should be paid to temperature control, salinity gradient changes and feeding strategies to ensure the healthy growth of the fry.

Disease prevention and management suggestions

Common diseases of Songjiang perch broodstock include bacterial gill rot, trichodinasis and cryptotrichopsia, which need to be prevented and controlled through scientific diagnostic methods.

Implementation suggestions

1. Pond preparation:Ensure that the pond is thoroughly disinfected and the water quality meets the standard requirements.
2. Broodstock selection:Strictly select healthy and disease-free broodstock according to quality standards.
3. Temperature and salinity control:Precisely control water temperature and salinity range according to seasonal changes.
4. Disease prevention:Regularly monitor water quality indicators and deal with abnormal situations in a timely manner.
