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.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.

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.

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.

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.
