海洋捕捞业的经济有效性和海洋生物种群的保护是当前海洋渔业经济研究的重点,应该将相关海洋物种的捕捞和繁殖规律统筹考虑,提高海洋渔业资源的利用效率。通过对Flaaten的生物经济学模型的数理分析比较,提出经济鱼种的价格上涨并不会导致该鱼种生物种群存量下降,如果管理措施合理,鱼类种群存量依然存在上升的可能;并由此指出海洋捕捞必须考虑种群间相互关系,利用合理的生物经济学模型、建立明晰的海洋捕捞权等措施有助于海洋生物经济的持续有效发展。
The economic efficiency of marine fisheries and the protection of marine organisms are the focuses of current marine fishery research. The fishing and multiplication rules of related marine species should be taken into consideration and the utilization efficiency of marine fishery resources should be improved. According to the mathematical analysis and comparison of Flaaten’s bioeconomic model, it is proposed that the price increase of economic species will not lead to the decline of the stocks of biological species, and if the management measures are reasonable, the stock of fish stocks still may rise; therefore, It is pointed out that ocean fishing must consider the interrelationship among populations, utilize reasonable bioeconomic models and establish clear marine fishing rights and other measures to help the sustainable and effective development of the marine biological economy.
