Global fishery resources of tuna-like species

This paper reviews the state of fishery resources of tuna and tuna-like species on a global scale, focusing on those most important commercially, i. e. the so-called principal market tuna species. These are classified as tropical tunas (skipjack, yellowfin and bigeye) and temperate tunas (albacore and bluefin [Atlantic, Pacific and southern]). For each tuna and tuna-like species, the document provides : taxonomic and other basic biological information, the development and expansion of the fishery, catch trends, institutional frameworks for regional cooperation in fisheries research, particularly stock assessment, procedures and input information for stock assessment, the status of the stocks, potential improvements in knowledge of the status of the stocks, and the future outlook for this status and catches.
