Türkiye’nin Kuzey Ege Kıyılarında Sade Uzatma Ağlarında Farklı Donam Faktörlerinin İzmarit (Spicara maena) Balığı Seçiciliği Üzerine Etkileri

Çanakkale Onsekiz Mart University Journal of Marine Sciences and Fisheries, 2020
The study was conducted at 0-30 meters depth, in the Northern Aegean coast of Turkey, between October 15, 2015 - October 15, 2017. In the study, 9 different gillnets (Mullet nets) having 18-20-22 mm mesh size and 0.35-0.50-0.65 hanging ratio were used ...

Investigating the Mesh Size Selectivity of Olive Flounder (Paralichthys olivaceus) Gillnets for Fisheries Resource Management in the East Sea

Fishes, 2023
This study aimed to evaluate the mesh selectivity of gillnets used in olive flounder (Paralichthys olivaceus) fishing by examining the distribution of total length (TL) across various mesh sizes.

Temporal trends and determinants of fish biomass in two contrasting natural lake systems: insights from a spring long-term monitoring scheme

Knowledge and Management of Aquatic Ecosystems, 2021
Freshwater fish declines are triggered by a suite of anthropogenic threats, including habitat degradation, climate and land use change, biological invasions, pollution and overfishing.

Looming-eyes buoys fail to reduce seabird bycatch in the Icelandic lumpfish fishery: depth-based fishing restrictions are an alternative

Royal Society Open Science, 2023
Bycatch in gillnets from lumpfish (Cyclopterus lumpus) fisheries is an important conservation issue in the north Atlantic, with up to 30 000 seabirds potentially killed each year. To date, no technical solutions exist to reduce the bycatch of seabirds in

Calibration of fish biomass estimates from gillnets: Step towards broader application of gillnet data

Ecological Indicators, 2023
Fish are an important component of aquatic ecosystems, thus representative and reliable assessments of their population variables are essential for a variety of ecological applications, management and conservation.

To ping or not to ping : the use of active acoustic devices in mitigating interactions between small cetaceans and gillnet fisheries [PDF]

, 2013
Active sound emitters (‘pingers’) are used in several gillnet fisheries to reduce bycatch of small cetaceans, and/or to reduce depredation by dolphins. Here, we review studies conducted to determine how effective these devices may be as management tools.

Foraging activity of harbour porpoises around a bottom-gillnet in a coastal fishing ground, under the risk of bycatch.

PLoS ONE, 2021
Bycatch of harbour porpoises (Phocoena phocoena) by gillnets is a recognised threat to populations. To develop effective mitigation measures, understanding the mechanics of bycatch is essential.

Experimental Mixed Gillnets Improve Catches of Narrow-Barred Spanish Mackerel (Scomberomorus commerson)

Fishes, 2023
A new gillnet made from multiple mesh sizes ranging from 125 to 180 mm of stretched mesh (experimental gillnet) was tested under commercial fishing conditions to compare the fishing performance with that of conventional gillnets with a 125 mm mesh ...

Distribution and Habitat Use of a Cryptic Small Cetacean, the Burmeister's Porpoise, Monitored From a Small-Scale Fishery Platform

Frontiers in Marine Science, 2018
There is widespread evidence that small-scale fisheries (SSF) bycatch threatens many populations of small cetaceans, yet conservation efforts are often limited by a lack of basic knowledge regarding their abundance, distribution, and habitat use.
