Impacts of fisheries on the Critically Endangered humpback dolphin Sousa chinensis population in the eastern Taiwan Strait

Endangered Species Research, 2013
Biological and fisheries data were analysed to assess the impact of fisheries mortality on a Critically Endangered subpopulation of 30% of the ETS Sousa subpopulation exhibited injuries caused by fishing gear.

Conventions in fresh water fishing in the prehistoric southern Levant: The evidence from the study of Neolithic Beisamoun notched pebbles

Journal of Lithic Studies, 2016
[Research Article] Fishing gear is not frequently found in archaeological sites in the southern Levant. Bone hooks were found as early as the later Epipalaeolithic period (mainly in Natufian culture sites) and continue to appear in small numbers until ...

Development of Low-Resistance Coastal Stow Net Using Numerical Analysis and Model Experiments

Fishes
In coastal stow net fishing, the heavy weight of a typical anchor (750–1000 kg) can increase the risk of capsizing the boat and crew member injury during hoisting operations. Thus, to prevent these accidents, a reduction in the anchor weight is required.

Exploring the relationship between static fishing gear, fishing effort, and benthic biodiversity: a systematic review protocol

Environmental Evidence, 2021
Background and objectives The environmental effects of static gear fishing include habitat-level effects such as permanent changes to the physical environment and the structure of the benthic and epibenthic communities.

Long‐term perceptions of freshwater anglers about abandoned, lost or discarded fishing gear during their fishing careers

Ecological Solutions and Evidence
Abandoned, lost or discarded fishing gear (ALDFG) represents a significant pollutant in wetland ecosystems globally. While the impacts of ALDFG are increasingly recognised as exacting a substantial toll on the world's oceans, reliable data on freshwater ...

Real-Time 3D Simulation for the Trawl Fishing Gear Based on Parallel Processing of Sonar Sensor Data

International Journal of Distributed Sensor Networks, 2014
A huge and a complex internal computation is required to visualize the underwater geometry of a fishing gear, because each particle of the gear should be calculated with consideration of several force vectors, such as the movements of the fishing vessel,

Validity of quantifying sensation of fishing reel using transmission error instead of sensory human evaluation for face gear design

Mechanical Engineering Journal, 2019
This paper discusses the determination of tooth-flank modification on a face gear system in order to improve the handle rotational sensation of a fishing spinning reel (hereafter, fishing reel sensation) and quantification of it.

Using Material Flow Analysis (MFA) to generate the evidence on plastic waste management from commercial fishing gears in Norway

Resources, Conservation & Recycling: X, 2020
Plastic debris is an ever-growing concern adversely affecting the coastal and marine ecosystem. Among marine plastic waste, a particularly troublesome waste fraction is Abandoned, Lost or Discarded Fishing Gears (ALDFG) that continues to trap marine life

Effect of gillnet mesh size on the capture probability and capture patterns in the Asian paddle crab (Charybdis japonica) fishery

Heliyon
In the Asian paddle crab (Charybdis japonica) gillnet fishery in the Yellow Sea, China, the minimum mesh size (MMS) regulation has been of a major importance due to high bycatch rates of undersized crabs. In this study, we evaluated how gillnet mesh size
