Hasil penelitian menunjukkan bahwa upaya penangkapan ikan oleh nelayan armada rawai permukaan dilakukan dengan menangkap ikan umpan terlebih dahulu selama perjalanan menuju lokasi penangkapan dengan hari efektif penangkapan selama 8 hari.

We analyzed hypothetical impacts for 25 of the most abundant species caught in the fishery by eliminating the 3 shallowest hook positions under scenarios with and without redistribution of these hooks to deeper depths. Las distribuciones variaron por especie: Surface longlines are mainly used to fish swordfish, albacore, tuna and some species of sharks, while bottom longlines are used to fish large Catch rates were estimated to be 0.
