TAILIEUCHUNG - A Responsible Approach To Marine Stock Enhancement

There are a number of viewpoints about the most likely direction of travel but it is clear that the best interests of the industry will be met through the re-letting process proceeding according to published schedules, as the DfT is doing, so that the commercial negotiations on new build versus continuous operation can take place as quickly as possible. While this takes place, we cannot be definitive on the balance between continued long-term use of existing fleets and new build that manufacturers, suppliers and leasing companies should built into their planning frameworks for CP5. This will become much. | American Fisheries Society Symposium 15 167-175 1995 Copyright by the American Fisheries Society 1995 A Responsible Approach to Marine Stock Enhancement H.

Leber The Oceanic Institute Makapuu Point Waimanalo Hawaii 96795 USA Abstract. Declining marine fish populations worldwide have rekindled an interest in marine fish enhancement. Recent technological advances in fish tagging and marine fish culture provide a basis for successful hatchery-based marine enhancement. To ensure success and avoid repeating mistakes we must take a responsible approach to developing evaluating and managing marine stock enhancement programs. A responsible-approach concept with several key components is described. Each component is considered essential to control and optimize enhancement. The components include the need to 1 prioritize and select target species for enhancement 2 develop a species management plan that identifies harvest opportunity stock rebuilding goals and genetic objectives 3 define quantitative measures of success 4 use genetic resource management to avoid deleterious genetic effects 5 use disease and health management 6 consider ecological biological and life-history patterns when forming enhancement objectives and tactics 7 identify released hatchery fish and assess stocking effects 8 use an empirical process for defining optimum release strategies 9 identify economic and policy guidelines and 10 use adaptive management.
