The large tuna resources of the Western and Central Pacific Ocean are delivering great economic benefits to Pacific Island countries and territories (PICTs) through sale of licences to distant water fishing nations and employment in fish processing. However, tuna needs to contribute to Pacific Island societies in another important way—by increasing local access to the fish required for good nutrition to help combat the world’s highest levels of diabetes and obesity.
A report is presented of a 2 day payao harvest aboard a commercial tuna catching vessel. The design of the payao (anchored floating, bamboo raft) is outlined, the most important feature of which is hanging line with coconut leaves tied to it, serving as a fish attractor. Recommendations are made to improve the system and to make it more durable and efficient.
The Tuna and Billfish Assessment Programme is a 3-year programme designed to provide a better understanding of the stocks of tuna and billfish throughout the central and western Pacific and also to determine the status of the stocks of the commercially important species. It will provide data as a basis for the assessment of optimum yields and will provide governments with information upon which sound fisheries development and resource management can be based. The specific topics to be covered by the Programme are listed.
It is widely recognised that anchored, nearshore fish aggregating devices (FADs) are one of the few practical ‘vehicles’ for increasing access to tuna to help feed the rapidly growing rural and urban populations in many Pacific Island countries and territories (PICTs). However, considerable planning, monitoring and research is still needed to understand and fulfil the potential of nearshore FADs.
The island countries of the South Pacific have adopted a regional approach to the development and management of tuna resources, through 2 organizations based in the region - the Forum Fisheries Agency and the South Pacific Commission. Details are given of the Tuna and Billfish Assessment Programme, which involves tropical tunas and albacore.
The present study reports the length-weight relationship of 11 species of baitfish from the pole and line fishery at Minicoy and S. delicatulus from the fishery at Agatti, Bangaram and Perumal Par.
Some problems associated with fitting surplus production models to unsuitable data are discussed. This is illustrated by an application of the Schaefer, Fox and PRODFIT models to Pacific Ocean bigeye tuna (Thunnus obesus ) catch and effort data for 1952-1987, which appear to be better described by purely empirical models.
The working together of the Solomon Islands and Japan on tuna (Katsuwonus pelamis ) industrialization requires cooperation and mutual trust. This must be based on an understanding of history and everchanging socioeconomic climates, which may be obtained from case studies such as that currently being funded by ICLARM and the Rockefeller Foundation on the South Pacific tuna industrialization.
Development of marine resources, especially tuna, is the key to national development for many newly-independent states of the South Pacific. They have industrialized fishing through joint ventures-collaborations between bost governments and multinational corporations. Based on two years' field research, this report illuminates the first decade (1971-1981) of a tuna fishing joint venture between Taiyo Gyogyo of Tokyo, the largest fishing company in the world, and the Solomon Islands Government.
Data from the Mexican purse seiner fleet operating in the eastern Tropical Pacific, for the year 1985-1990, are used to show that the fraction of surface schools of yellowfin tuna Thunnus albacares associated with dolphins (Stenella attenuata and others) increases with sea surface temperature. Possible reasons for this correlation are briefly discussed.
