“…Wahoo (Acanthocybium solandri) is almost exclusively associated with surface waters, spending the vast majority of its time above the thermocline, but periodically diving to depths of up to 286 m [137,138]. The results of a tagging study conducted off the coast of California suggest that wahoo are subject to temperatures between 10 and 30 • C but tend to spend most of the time (98%) in waters above 22 • C [138,139].…”

Migrations of large pelagic fishes across the Pacific are usually inferred from tagging or genetic studies. Even though these techniques have improved over time, they still fail to demonstrate large transoceanic migrations, usually proposing ‘routes’ that do not cycle seasonally. The current study uses the concept of ‘philopatry’ in 11 large pelagic fish species, i.e., the tendency for animals to return to their natal site to reproduce. Tentative migration routes and maps emerge by applying this concept to the movements extracted through a comprehensive review of the literature on satellite and conventional tagging, and population and subpopulation linkages inferred from genetic and/or genomic studies. Moreover, when comparing these proposed migration routes and the mapped reconstructed catch (1950–2016, Sea Around Us) of each species in the Pacific, similarities emerge, reinforcing the accuracy of these migration cycles informed by philopatry. Finally, by superposing the migration routes of our 11 species, we identified areas of the Pacific that are part of the inferred migration routes of multiple species, leading to a discussion of possible ‘blue corridors’ that would protect the studied species’ key migration routes and stocks, which are important for the fisheries, culture and nutrition of Pacific islanders.

Peluang keberhasilan operasi penangkapan ikan dengan jaring insang hanyut sangat ditentukan oleh arah ruaya ikan terhadap posisi jaring. Ikan akan tertangkap jika arah renangnya terhadang oleh jaring. Penelitian mencoba meningkatkan peluang ikan tertangkap dengan memanfaatkan lampu celup. Tujuannya untuk menunjukkan bahwa penggunaan lampu celup akan meningkatkan jumlah ikan hasil tangkapan tanpa mengurangi komposisi jenisnya. Dua unit jaring insang dioperasikan secara bersamaan. Salah satu unit jaring insang dilengkapi dengan lampu celup. Hasil penelitian menunjukkan penggunaan lampu celup tidak mempengaruhi komposisi jenis ikan yang tertangkap, tetapi hanya mempengaruhi jumlah tangkapannya. Jumlah total ikan hasil tangkapan jaring insang yang dilengkapi lampu celup mencapai 3.521 ekor, atau 58,82% dari seluruh ikan hasil tangkapan, sedangkan jaring insang tanpa lampu celup sebanyak 2.465 ekor (41,18%). Rincian hasil tangkapan jaring insang yang dilengkapi lampu celup dan tanpa lampu celup adalah mackerel tuna (Euthynnus affinis) sebanyak 218 ekor dan 129 ekor, spanish mackerel (Scomberomorus commerson) (80; 50), needlefish (Tylosurus crocodilus) (7; 3), Indo-Pacific sailfish (Istiophorus platypterus) (4; 2), driftfish (Psenes cyanophrys) (2.838; 2.051), dan moonfish (Mene maculata) (374; 230).
