“…In the study of fish biology, body weight was often considered as the uppermost indicator to measure the body size of fish, followed by body length [ 23 , 24 ]. As revealed by comparing the statistical results of diverse ages, the average weight of P. pekinensis grows from 80.54 to 699.55 g from 1 to 3 ages, with growth rate of 769%, which indicated that P. pekinensis grew tremendously fast.…”

Parabramis pekinensis was treated as research object in order to investigate the correlation between morphological traits and body weight. We measured 9 morphological indexes including total length (X1), body length (X2), body height (X3), head length (X4), snout length (X5), eye diameter (X6), eye distance (X7), caudal stalk length (X8) and caudal stalk height (X9). The principal morphological traits affecting body weight were screened out and the regression equation was established. The regression equation of Y1 (age 1 group) shape character (X) and weight (Y) was Y = − 169.183 + 32.544 × 3 + 10.263 × 4 + 15.655 × 7. The regression equation of Y2 (age 2 group) shape character (X) and weight (Y) was Y = − 694.082 + 7.725 × 1 + 72.822 × 3 + 77.023 × 6, the regression equation of Y3 (age 3 group) shape character (X) and weight (Y) was Y = − 1161.512 + 26.062 × 1 + 22.319 × 2- 107.218 × 5 + 83.901 × 7. Gene expression was consistent with these conclusions. TOR signaling pathway expression raised in Y1 then width increased. And GH-IGF-1 signaling pathway expression raised in Y2 then the length increased. In conclusion, the paper could prove that P. pekinensis showed a growth trend, which was increasing width first and length later. In some sense, the study not only enriched the basic biological data of P. pekinensis, but also provided waiting morphological traits for selective breeding of P. pekinensis artificial breeding in future.

“…growth-related traits have been performed in many aquatic species, including Apostichopus japonicaspearl (Zhan et al, 2019), Glossaulax reiniana (Zhao et al, 2014) Pinctada martensii (Deng et al, 2008), Exopalaemon carinicauda (Zhang et al, 2013a) and Patinopecten yessoensis (Chang et al, 2008). In fish species, the main traits affecting the body weight of male tilapia were its full length, depth at caudal peduncle, body width and head length.…”
