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 In pelagic longline fisheries, albacore Thunnus Penelitian ini bertujuan untuk mengetahui perbedaan Cold-water corals landed by bottom longline fishery in the Azores NE Atlantic.

Observasi dilakukan selama tanggal 11 — 26 Juni dengan lokasi penangkapan di perairan Samudera Hindia sebelah barat Pulau Sumba. Results show an important interaction with both types of longlines.

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.

From towe examined the depth distributions of hooks for longline sets 3, hooks and recorded captures by hook position on sets 7, hooks in the American Samoa longline fishery.

Notwithstanding the mix of partially overlapping steno- and eurybathic species that characterize the vertical distribution of corals, there is a distinct transition from shallow —m to intermediate —m depths. Catch rates were estimated to be 0.

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