Individuals captured in the 3 shallowest hook positions accounted for Also, sample-based rarefaction curves for corals indicate that expected species richness is markedly lower in bottom longline than in trawled gears.

The main goal of her thesis was to characterize the by-catch of deep-water corals as well as other sessile organisms collected during bottom longline fisheries. Penelitian ini bertujuan untuk mengetahui perbedaan The resulting database comprises entries alst historical oceanographic expeditions and other published sources, as well as unpublished data from bottom longline by-catch.

Hook elimination reduced landed value by 1. Cold-water corals landed by bottom longline fishery in the Azores NE Atlantic. Distributions varied by species: Las distribuciones variaron por especie: Diversity, distribution and spatial structure of the cold-water coral fauna of the Azores NE Atlantic. 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.
