Abstract: In order to quantitatively analyze the impact of aquatic science and technology promotion on fishermen's income, the number of aquatic promotion stations, the scale of promotion personnel, promotion funds, technical guidance area and fishermen's public information service were selected to reflect the effectiveness of aquatic science and technology promotion. Based on the fishery time series data of Hubei Province from 2007 to 2017, a multiple linear regression model was established, and the impact of these factors on fishermen's income in Hubei Province was analyzed with reference to Jiangsu Province and Hunan Province. The results showed that the per capita income of fishermen in Hubei Province was highly correlated with fishermen's public information services, fishery promotion funds and the scale of fishery promotion personnel, and the degree of influence decreased in turn. Accordingly, targeted countermeasures and suggestions such as improving the level of information technology, increasing funding for extension, and enriching the team of promotion talents were put forward.
