Abstract Based on the bottom trawl investigation data from 2017 to 2018, the growth, mortality and development status of 5 species of economic fish in coastal Dalian, China were evaluated using FISAT Ⅱ software developed by the Food and Agriculture Organization of the United Nations (FAO). These species were small yellow croaker Larimichthys polyactis, rockling Enchelyopus elongates, pointhead plaice Cleisthenes herzensteini, greenling Hexagrammos otakii, and schlegeli's black rochfish Sebastes schlegeli. The growth and death parameters were estimated using the body length frequency distribution method (ELEFAN Ⅰ), and the resource change trend were evaluated according to the Beverton-Holt model. The results showed that the asymptotic length of 5 fish species were from 222.4 mm to 495.5 mm, and that growth parameter was veried from 0.36 to 0.69. The current exploitation of 5 fish species were from 0.57 to 0.71, and were all larger than 0.5 and Emax, suggesting the stocks were over-exploited. Combined with the Beverton-Holt dynamic model, the result showed that the fishing pressure of the 5 fish species were relatively high, and the current capture size were relatively small. Considering inflection age, critical age, recruitment and economic interest, the optimum capture size for small yellow croaker, rockling, pointhead plaice, greenling, and schlegeli's black rochfish were 136 mm, 237 mm, 207 mm, 297 mm, and 160 mm, respectively. The findings can be used as a reference for fishery resources management of these five economic fish species. In the specific fishery policy-making, it is also necessary to ensure the timeliness of survey data and the comprehensiveness and scientificity of survey methods.
