摘要： To study the growth and development rules of the longfin batfish Platax teira, three nonlinear models, logistic, Gompertz and Bertalanffy, were used in the study to fit and analyse the body height, body length, full length and body weight growth curves of the fish at the age of 2-8 months. The results showed that the three nonlinear curves could fit the body height, body length, full length and body weight growth curves of the P. teira well, and the fitting degree was above 0.99. Considering various factors of the models, the Gompertz model had the best fitting degree for body height, body length, full length and body weight. Under the optimal model, the monthly age of the inflection point of body height, body length, full length and body weight was 3.72, 7.28, 6.60 and 8.88, respectively; the inflection point body size or weight was 10.81 cm, 17.82 cm and 20.14 cm and 826.70 g, respectively. The results of the experiment preliminarily revealed the growth and development rules and growth characteristics in the early stage, which provide a reference for the feeding management and feeding strategies of P. teira.
