recommendations! Published in 2020 at "Aquaculture and Fisheries"

DOI: 10.1016/j.aaf.2020.05.001

Abstract: Penaeid trawls often have poor ecological efficiencies measured as unwanted bycatches (with high discard mortality) and read more here.

DOI: 10.1016/j.fishres.2018.02.009

Abstract: Abstract Bottom-trawl surveys are widely used to generate data for developing habitat suitability models for rockfish species. However, bottom trawl selectivity varies with substrate type and can lead to biased and unreliable model outputs. Bottom-set… read more here.

DOI: 10.1016/j.marpol.2020.104241

Abstract: Abstract To ensure that benefits from capture fisheries accrue to the nationals, fisheries regulations and acts prioritise local access and harvest rights in near and distant waters within a nation’s exclusive economic zone (EEZ). The… read more here.

recommendations! Published in 2020 at "Ocean Engineering"

DOI: 10.1016/j.oceaneng.2020.106989

Abstract: Abstract A hyper-lift trawl door (HLTD) which is not heavily dependent on the bottom for its hydrodynamic performance was developed for both bottom and midwater trawling. Flume tank experiments were conducted on simplified HLTD models… read more here.

recommendations! Published in 2017 at "ICES Journal of Marine Science"

DOI: 10.1093/icesjms/fsw250

Abstract: Assumptions about gear efficiency and catchability influence estimates of abundance, mortality, reference points and catch potential. Despite the need to better quantify fishing effects on some target species and on many non-target species taken as… read more here.

Multi‐Taxon Predictions of Deep‐Sea Corals and Sponges From Stacked Species Distribution Models in the United States West Coast Exclusive Economic Zone and Relation to Trawl Closure Zones

recommendations! Published in 2025 at "Diversity and Distributions"

DOI: 10.1111/ddi.70005

Abstract: Abundant species distribution models (SDMs) of deep‐sea corals and sponges (DSCS) allow one to make community‐level predictions about DSCS. Pairing that with the conservation information of Vulnerable Marine Ecosystems (VMEs) due to their sensitivity to… read more here.

recommendations! Published in 2018 at "Canadian Journal of Fisheries and Aquatic Sciences"

DOI: 10.1139/cjfas-2016-0461

Abstract: We developed and evaluated an innovative trawl technology that reduces seabed contact while targeting northern shrimp (Pandalus borealis) off the east coast of Canada. The innovative footgear, referred to as the “aligned footgear”, was evaluated… read more here.

recommendations! Published in 2024 at "Mediterranean Marine Science"

DOI: 10.12681/mms.37470

Abstract: Benthic species and habitats are receiving increasing attention in the framework of European regulations such as the Marine Strategy Framework Directive (MSFD) and the implementation of the Ecosystem Approach to Fisheries Management by the current… read more here.

Trawling in the Mediterranean: An Exploration of Empirical Relations Connecting Fishing Gears, Otterboards and Propulsive Characteristics of Fishing Vessels

Sign Up to like & get
recommendations! Published in 2019 at "Frontiers in Marine Science"

DOI: 10.3389/fmars.2019.00534

Abstract: Fishing pressure is often expressed in terms of vessel’s physical attributes, like tonnage and engine power, while a common definition of fishing capacity identifies vessel size as a convenient proxy for the size of gear… read more here.
