Abstract: Growth performance is an important character in the breeding of new varieties(strains) of fish, and the factors that affect the growth performance of cultured fish mainly include gene, environment aquaculture activities and human interference. From 1996 to 2021, 120 fish breeding varieties were identified in China, but some of them were not applied to commercial production due to the lack of a relatively unified evaluation standard or specification for testing technology. In this paper, the identification and testing technology status of new varieties(strains) of cultured fish were systematically introduced; the main influencing factors in growth performance test and evaluation were analyzed, and a set of technical suggestions were put forward for establishing test base, test platform, improving test design, strengthening breeding management, reducing human interference, scientific data collection, result evaluation and judgment. It could provide feasible technical reference for the construction of new fish varieties (strains) testing ground, scientific, standardized and fair testing and evaluation of new fish varieties (strains) in China, and could also provide reference for the construction and testing of other aquaculture varieties (strains) testing ground.

Key words: new fish varieties, growth performance, testing and identification of new varieties
