On Selectivity Curve of Gillnet
NIPPON SUISAN GAKKAISHI, 1971 The preceding paper showed that the mesh selectivity, i.e. relative efficiency, of gillnet was expressed as a function of the ratio of mesh size m to body length l in certain ranges of mesh size and length, and that the application of the above method to McCOMBIE and FRY's, and ISHIDA's data gave different master curves according to the groups of ...

A Scenario Tool for Sustainability Transformation in Fisheries and Beyond
Sustainable Development, EarlyView.ABSTRACT The urgency to find sustainable management solutions intensifies with increasing natural resource scarcity. Resource sectors are usually characterized by diverse resource users. We developed a structured scenario tool designed to quantitatively assess policy options for achieving sustainability, accounting for ecological, economic and ...

Use of floated gillnet to reduce flatfish bycatch in a mixed-species gillnet fishery
Estuarine, Coastal and Shelf ScienceBycatch of threatened flatfish species is a major concern in mixed-species bottom-set gillnet fisheries in the Yellow Sea, China. Therefore, we tested floated gillnets against standard bottom-set gillnets to reduce bycatch by exploiting difference in species-specific fish behavior.

Examining the Role of Economic Complexity and Climate Readiness in the Climate‐Fishing Nexus
Sustainable Development, EarlyView.ABSTRACT This paper investigates the climate‐fisheries association in Gulf Cooperation Council (GCC) nations from 1999 to 2022. A key objective is to explore the role of both the economic complexity index (ECI) and the climate readiness factor (READ) in the climate‐fishing nexus.

Wildlife Biology, EarlyView.Freshwater turtles play vital roles in maintaining the health of aquatic ecosystems by supporting ecological balance, nutrient cycling and regulating prey populations. Unfortunately, they are among the most threatened species worldwide. Habitat fragmentation, illegal trade, overharvesting for meat, and use in ethnomedicinal practices have severely ...

Applied Sciences, 2021 Although gillnet fisheries are increasingly common in Korea, few studies have conducted sea trials using tie-down gillnets. Here, we analyzed the mesh size selectivity using tie-down gillnets with four different mesh sizes (84, 90, 105, and 120 mm) to ...
