CONSTRUCTION ANALYSIS OF BOTTOM GILLNET AS AN ALTERNATIVE TO BOTTOM TRAWL IN PEKALONGAN WATERS [PDF]
Russian Journal of Agricultural and Socio-Economic Sciences, 2019 A bottom trawl is a fishing tool that is not recommended by the government to capture demersal fish resources in Pekalongan waters. Therefore, a bottom gillnet is an alternative substitute for bottom trawl fishing gear in catching demersal fish.

Bottom trawl fishing footprints on the world's continental shelves. [PDF]
Proc Natl Acad Sci U S A, 2018 Significance We conducted a systematic, high-resolution analysis of bottom trawl fishing footprints for 24 regions on continental shelves and slopes of five continents and New Zealand. The proportion of seabed trawled varied >200-fold among regions (from 0.4 to 80.7% of area to a depth of 1,000 m).

Turning the tide on bottom trawling [PDF]
Aquatic Conservation: Marine and Freshwater Ecosystems, 2015 Trawling is universally recognized as one of the most destructive fishing methods, causing irreversible damage through scraping large tracts of bottom habitats. These habitats then suffer from declines in ecosystem functions and services, and collapses in populations of trawled species. The plethora of studies on the unsustainable impacts of commercial

Impact of bottom trawling on sediment biogeochemistry: a modelling approach [PDF]
Biogeosciences, 2020 Abstract. Bottom trawling in shelf seas can occur more than 10 times per year for a given location. This affects the benthic metabolism, through a mortality of the macrofauna, resuspension of organic matter from the sediment, and alterations of the physical sediment structure.

Effects of bottom trawling on fish foraging and feeding [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2015 The effects of bottom trawling on benthic invertebrates include reductions of biomass, diversity and body size. These changes may negatively affect prey availability for demersal fishes, potentially leading to reduced food intake, body condition and yield of fishes in chronically trawled areas.

Testing of a helix twine off-bottom trawl on Georges Bank
Frontiers in Marine Science, 2023 The massive biomass of Eastern Georges Bank haddock (Melanogrammus aeglefinus) is difficult to harvest without capturing less robust, but still valuable groundfish stocks like Atlantic cod (Gadus morhua) and some flatfish species.
