Laboratory study of the impact of repetitive electrical and mechanical stimulation on brown shrimp Crangon crangon [PDF]

, 2016
Pulse trawling is currently the best available alternative to beam trawling in the brown shrimp Crangon crangon and Sole Solea solea (also known as Solea vulgaris) fisheries.

Quantity and biochemical composition of particulate organic matter in a highly trawled area (Thermaikos Gulf, Eastern Mediterranean Sea)

Advances in Oceanography and Limnology, 2015
Bottom trawling represents nowadays one of the most severe anthropogenic disturbances at sea, and determines large impacts on benthic communities and processes.

Estimating Spatiotemporal Fishing Effort of Trawlers with Vessel-Monitoring System Data: A Case Study of the Sea Area of the Bohai Sea and the Yellow Sea, China

Journal of Marine Science and Engineering, 2023
Measuring the distribution of the fishing effort of trawlers is of great significance for describing marine fishery activities, quantifying fishing systems in terms of marine ecological pressure, and revising the regulations of fishing.

Stable isotopes reveal the effect of trawl fisheries on the diet of commercially exploited species

Scientific Reports, 2017
Bottom trawling can change food availability for benthivorous demersal species by (i) changing benthic prey composition through physical seabed impacts and (ii) by removing overall benthic consumer biomass increasing the net availability of benthic prey ...

Investment prospects in inshore trawling in Nigeria [PDF]

, 1987
Commercial trawling for finfish in Nigeria's inshore water is a recent activity. Intensive industrial trawling started when the Federal Government distributed trawlers to viable fishermen cooperatives during the Third National Development Plan Period ...

The impact of Rapido trawling for scallops, Pecten jacobaeus (L.), on the benthos of the Gulf of Venice [PDF]

, 1999
Rapido trawls are used to catch sole around the coast of Italy and to catch scallops in the northern Adriatic Sea but little is known about the environmental impact of this gear.

The influence of rivers on seabird foraging ecology

Biological Reviews, EarlyView.
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

Modelling potential impacts of bottom trawl fisheries on soft sediment biogeochemistry in the North Sea†

Geochemical Transactions, 2001
Bottom trawling causes physical disturbance to sediments particularly in shelf areas. The disturbance due to trawling is most significant in deeper areas with softer sediments where levels of natural disturbance due to wave and tidal action are low.

A lightweight clear liquid optical chamber baited remote underwater video system for monitoring fish in turbid coastal wetlands

Limnology and Oceanography: Methods, EarlyView.
Abstract Clear liquid optical chamber baited remote underwater video systems (CLOC‐BRUV) are an effective option for assessing fish assemblages in turbid water, but current designs are limited by their large size and high operational costs. We developed a lightweight CLOC‐BRUV unit and evaluated its performance through proof‐of‐concept trials and field

Preservation of juvenile hake (Merluccius merluccius L) in the western Mediterranean demersal trawl fishery by using sorting grids

Scientia Marina, 2004
The Mediterranean fishery has experienced a decline in catches over the past 20 years due to an excessive increase in effort caused by both increased trawler engine power and rapid technological advances in fishing technology and fish location.
