Economic linkage impacts of Hawaii’s longline fishing regulations
Fisheries regulations driven by environmental concerns would not only directly affect fisheries sectors but also tend to indirectly influence other sectors through intersectoral input–output linkages. This paper examines both backward and forward linkages of Hawaii’s fisheries sectors to the rest of the economy, and based on this evaluates the potential economic impacts of longline fishing regu...
متن کاملTuna Longline Fishing around West and Central Pacific Seamounts
BACKGROUND Seamounts have been identified as aggregating locations for pelagic biodiversity including tuna; however the topography and prevailing oceanography differ between seamounts and not all are important for tuna. Although a relatively common feature in oceanic ecosystems, little information is available that identifies those that are biologically important. Improved knowledge offers oppo...
متن کاملIdentifying Taxonomic Groups Vulnerable to Bottom Longline Fishing Gear in the Ross Sea Region
Implementing measures to avoid significant adverse impacts to vulnerable marine ecosystems (VMEs) requires a specific list of the taxa that are considered vulnerable in the fishery being assessed. New Zealand identified an interim list of taxa to monitor in fishery by-catch in the Ross Sea as part of its benthic fisheries impact assessment. The rationale for including or excluding each taxonomi...
متن کاملRelation between Hook Depth and Fishing Efficiency in Surface Longline Gear
The longline gear employed in this study consisted of "baskets" between floats (Fig. 1). Float lines measured about 7m, while the main line within each basket measured about 1200 m. Branch lines (33 per basket) were 15m long. This standard gear design is modified by ences by each species. Suzuki et al. (1977) state that the same fishing methods and longline gear are frequently used regardless o...
متن کاملAn oceanographic characterization of swordfish (Xiphias gladius) longline fishing grounds in the springtime subtropical North Pacific
During January–May, surface manifestation of multiple, individual basin-scale fronts accentuate the central North Pacific Subtropical Frontal Zone (STFZ) system. The most prominent of these fronts are climatologically located at 32 )34 N and at 28 )30 N latitudes [herein nominally referred to as the ‘Subtropical Front’ (STF) and the ‘South Subtropical Front’ (SSTF), respectively], although cons...
