Bottom Trawling

2019
Bottom Trawling. One of the most common ways to catch fish is by dragging nets along the seafloor. This causes changes in the plants and animals that live there. When the same areas are trawled frequently, the community on the seafloor can be drastically changed. Long-lived species such as corals and sponges are severely affected.

Reply to: Quantifying the carbon benefits of ending bottom trawling

Nature, 2023
[Extract] In the accompanying Comment, Hiddink et al.1 challenge our estimate2 of the magnitude of seabed carbon remineralized by bottom trawling. However, we think that the conclusions by Hiddink1 are based on incorrect assumptions and that these conclusions lack quantitative support for several of their claims.

Cable behavior in bottom trawling

Ocean Engineering, 1985
Abstract A method of numerical analysis based on iterative solutions of quasi-linearized differential equations describing the behavior of long cable segments is developed. The method is implemented in a computer program for use on small computer facilities, such as desktop-sized computers.

Effects of bottom trawling on ecosystem functioning

Journal of Experimental Marine Biology and Ecology, 2008
By combining field observations with data from controlled mesocosm experiments this study demonstrated that bottom trawling has the potential to cause long-term impacts on sediment nutrient fluxes. Field observations confirmed that trawling reduced the density of important bioturbators in the study area, but revealed only weak effects of trawling on ...

Preliminary bottom trawling experiments with a newly designed separator fish trawl

Fisheries Research, 1991
Abstract A separator trawl was designed by introducing a short horizontal panel of net webbing between the upper and lower belly of a 29.7 m/34.2 m (head rope/foot rope) high opening bottom trawl (HOBT), dividing the net into two equal horizontal compartments terminating in two independent codends.
