Research and Analysis on Beihai Fishery Optimal Revenue Model Using Barycenter Method under Different Seawater Temperature

It is speculated that the changes in seawater temperature may cause population migration of the North Sea Mackerel and Herring fisheries. To assess the situation and propose some remedies which can help improving the economy, the paper establish a series of models. The paper set a revenue-cost model to figure out the maximum sailing distance and area by willingness of fishermen to define how migration of mackerel and herring influence the net profit of companies. The longer distance brings the larger total cost, the smaller total revenue, and the smaller net profit. The paper establish the total cost-time model which divide to fixed assets, wage, and fuel fare and the total revenue-time model which is influenced by freshness, to define the maximum sailing distance. Combining with the prediction of fisheries, it is clearly that fisheries will migrate out of the willingness area completely 78 years later. To avoid the awful condition of fishing, suggest fishermen take some strategies to reduce the loss of fish migration. According to the Barycenter method, consider Anstruther, Eyemouth and Buckie as the best three city for fisheries by using the administrative division of Scotland and the prediction of fisheries. Or fishermen can buy a certain percent advanced equipment according to the maximum net profit model.
