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 Science
Bycatch 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.

Gillnet colour affects catch efficiency in pearlspot (Etroplus suratensis) tropical estuary fishery

Aquaculture and Fisheries
Gillnets are one of the most commonly used fishing gears in both marine and inland waters. Different colour filament nettings are often used in gillnets. However, the effect of gillnet colour on catch efficiency is unclear for most fisheries.

Fishing for Atlantic cod (Gadus morhua) with pots and gillnets: A catch comparison study along the southeast coast of Labrador

Aquaculture and Fisheries, 2022
Gillnets are the primary fishing gear used to catch Atlantic cod (Gadus morhua) in coastal areas of Newfoundland and Labrador but are known to catch non-target species and produce lower quality fish than live-catch methods.

Does innovation success need advocacy? Stakeholder involvement in firm innovation

Strategic Management Journal, EarlyView.
Abstract Research Summary Prior research documents that firms often collaborate with advocacy groups to mitigate stakeholder contention. Integrating stakeholder theory into a performance model of collaborative innovation, we propose an overlooked explanation for such collaborations: to enhance the adoption of firms' innovations.

Trace Element Contamination in Top Predatory Elasmobranchs From the Southern Black Sea: Implications for Ecosystem Health and Risk Assessment

Environmental Toxicology, EarlyView.
ABSTRACT Environmental pollution resulting from the rapid increase in human population, urbanization, intensive use of chemicals in agriculture, and industrial development has reached a level that threatens natural life today. Trace elements are one of the most important factors causing significant levels of pollution in the environment and are added ...
