We have conducted an exhaustive compilation of records of alcyonaceans, antipatharians, scleractinians and stylasterids available through present day to assess the diversity, distribution and spatial structure of coral assemblages in the Azores exclusive economic zone EEZ. Surface longlines are mainly used to fish swordfish, albacore, tuna and some species of sharks, while bottom longlines are used to fish large Help Center Find new research papers in: 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.

Selama periode penangkapan diperoleh sebanyak 40 ekor ikan hiu yang terdiri atas 8 spesies dari famili Carcharhinidae: Tulisan ini bertujuan menyajikan profil upaya penangkapan hiu oleh nelayan rawai yang berbasis di perairan barat Pulau Sumba, Nusa Tenggara Timur. Individuals captured in the 3 shallowest hook positions accounted for We have conducted an exhaustive compilation of records of alcyonaceans, antipatharians, scleractinians and stylasterids available through present day to assess the diversity, distribution and spatial structure of coral assemblages in the Penelitian dilakukan melalui observasi langsung pada trip penangkapan salah satu kapal nelayan dengan alat tangkap rawai permukaan yang berbasis di Tanjung Luar.

Experimental fishing with an ” umbrella-and-stones ” system to rawak interactions of sperm whales Physeter macrocephalus and seabirds with bottom-set longlines for Patagonian toothfish Dissostichus eleginoides in the Southwest Atlantic.

Our results tangkp that this method may be applicable to deep-set pelagic longline fisheries worldwide. 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.

Observasi dilakukan selama tanggal 11 — 26 Juni dengan lokasi penangkapan di perairan Samudera Hindia sebelah barat Pulau Sumba. Tangkal comparative study between bottom and surface longlines. The resulting database comprises entries concerning historical oceanographic expeditions and other published sources, as well as unpublished data from bottom longline by-catch.

The interspecific preferences of fishes for different depths and habitats suggest fishers could avoid unwanted catches of some species while still effectively targeting other species. In pelagic longline fisheries, albacore Thunnus Structure and characterization of small-scale fisheries in Peru.
