Introduction

National Standard of the People's Republic of China GB/T 32756-2016 Sea Cucumber Parents and Seedlings In-depth Interpretation

Background of Standard Formulation and Analysis of Technological Evolution

GB/T 32756-2016 Sea Cucumber Parents and Seedlings is a standard formulated to regulate the quality assessment of parent and seedlings in the process of sea cucumber breeding. With the rapid development of aquaculture, especially the expansion of sea cucumber breeding, the quality requirements for parent and seedlings are increasing. This standard combines the actual needs of sea cucumber breeding in my country and refers to international advanced technologies to ensure that the product quality meets the requirements of pollution-free food.

Technological Evolution Analysis

This standard was drafted based on the rules of GB/T1.1-2009 and absorbs the latest research results in the field of sea cucumber breeding at home and abroad. Its core content includes the source, specifications, quality requirements, inspection methods and transportation requirements of parent and seedlings.

Comparison and analysis of standard frameworks

Project dimensions	Parent requirements	Seedling requirements	Standard basis
Specification classification	- Weight ≥ 200g, body length ≥ 20cm	- According to weight, it is divided into temporary, small, medium and large specifications	Table 1 Specification classification of sea cucumber seedlings
Quality requirements	- No injuries or discharge on the body surface	- Healthy appearance, strong vitality, and bright body color	Table 2 Quality requirements for sea cucumber seedlings
Safety Testing	- Detection of banned drugs such as chloramphenicol, nitrofuran metabolites and malachite green	- Restricted drugs are implemented in accordance with NY5070	GB/T21311, GB/T20361

Explanation of professional terms and practical application cases

Term analysis

Body length: The longitudinal length of the sea cucumber when it stretches horizontally naturally, which is an important indicator to measure its growth status.
Rate of wounded and broken individuals: The proportion of wounded and broken individuals in seedlings, reflecting the breeding environment and management level.
Rate of qualified individuals for specifications: The proportion of seedlings that meet a specific weight range, which is a key indicator for quality assessment.

Actual application case

In a large sea cucumber farm, the survival rate and product quality were significantly improved by strictly selecting parent cucumbers according to the GB/T 32756-2016 standard and classifying and cultivating seedlings. Specific measures include:

Parent cucumber selection: Priority is given to using high-quality parent cucumbers provided by sea cucumber original breeding farms at all levels.
Seedling management: Through specification classification and health screening, the qualified rate of large-size seedlings is ensured to reach more than 95%.
Transportation optimization: The dry transportation method combined with foam box insulation technology significantly reduces the mortality rate during transportation.

Implementation suggestions and precautions

In order to ensure the effective implementation of GB/T 32756-2016 standard, the following suggestions are for reference:

Parent selection:Give priority to healthy individuals that meet the weight and length requirements, and establish a complete parent file.
Seedling cultivation:Strengthen water quality management to ensure compliance with GB11607 fishery water quality standards, and strictly control the dosage of drugs.
Quality testing:Periodically sample and test seedlings, focusing on indicators of deformity rate and disability rate.
Transportation and storage:Use scientific transportation methods to ensure stable water temperature and salinity, and avoid discharge of dirt caused by stress response.
