Kegiatan penangkapan hiu sebagai target tangkapan utama tangkpa perikanan rawai di Tanjung Luar, Lombok Timur berlangsung sepanjang tahun dengan upaya penangkapan yang terus meningkat. Tulisan ini bertujuan menyajikan profil upaya penangkapan hiu oleh nelayan rawai yang berbasis di perairan barat Pulau Sumba, Nusa Tenggara Timur.

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 Structure and characterization of small-scale fisheries in Peru. Vulnerability of deep-water corals of the Azores to demersal fisheries.

The interspecific preferences of fishes for different depths and habitats suggest fishers could avoid unwanted tangkao of some species while still effectively targeting other species.

Hook elimination reduced landed value by 1. Log In Sign Up. Biogeosciences, 10, —, doi: Elasmobranchii; konservasi; laju tangkap; rawai; Tanjung Luar; Lombok Timur.

Results show an important interaction with both types of longlines.

Surface longlines are mainly used to fish swordfish, albacore, tuna and some species of sharks, while bottom longlines are used to fish large bottom-dwelling fish such as groupers.

Based on these scenarios, redistribution of hooks to deeper depths may provide an economically feasible modification to longline gear that could substantially reduce bycatch for a suite of vulnerable species.
