Study on medium to long term forecasting of squid in the Northwestern Pacific
摘要
Abstract
In order to better predict resource of squid in the Northwestern Pacific, it is very important to develop a prediction system based on an appropriate forecasting method. The correlation analysis was used to filter out key mesh points that significantly affect resource of squid in spawning areas. Data samples were organized by using sea-surface temperature (SST) at these mesh points, the ratio between the area with suitable temperature and the whole spawning areas, and catching amount per unit of effort (CPUE). Prediction experiments have been conducted by using linear regression, BP network, RBF network and support vector machine. Results showed that BP neural network is much better than other methods during medium and long term prediction of squid in the Northwestern Pacific. The resource forecasting system built based on correlation analysis and BP neural network is effective and feasible.关键词
