Composition of Service Value of Fisheries Resources
论渔业资源服务价值的构成

The inadequacies of understanding the service value of fisheries resources are one of the primary reasons for the trouble of fisheries development and sustainability in the world. The majority of fisheries resources have been fully exploited, declining, or even depleted, as a direct result of over-fishing and the overcapacity of fishing fleets. Enhancing understanding of the service value of fisheries resources plays a key role in decision-making of fisheries resources management. Based on the concept of Total Economics Value (TEV), the composition of service value of fisheries resources is discussed in this paper. The value of fisheries resources, as the service to humans and other life systems, is a result of their functions and stems from the existence of fisheries resources as a life system. The service value of fisheries resources involves the utility value and the non-utility value. The utility value comprises the use value, ecology value, and option value. The use value of fisheries resources displays as a material supplier to human economic activities, which sustains the society and economy development, including aquatic product value of food provision service for humans and raw material provision service for industries, the labor value to offer employment opportunities for fishermen whose livelihood relies on fishing, the recreational value of spirit enjoyment service for recreational activities or sports, the aquatic germ plasm value of sinensis and larvae provision service for aquaculture, and the culture value of service for scientific research, education, artistic creation, and cognition development. The ecology value of fisheries resources encompasses the services of providing baits or foods support to other organism or life systems pertaining to the same ecosystem, and the services of the maintenance of ecosystem nutrients circulation and the balance of species in the same ecosystem. The option value of fisheries resources involves the value that the resources are reserved to support other options, or support future ability to use fisheries resources as a quasi option value and the inheritance value in years to come. The non-utility value, expressed as the existence value or intrinsic value, is based on ethics or even culture and religious. It would directly affect the implementation of policies associated with fisheries resources and the management measures, and should not be ignored in the decision-making process of fisheries resource management.
