This paper from is yet another in a wealth of research that demonstrates the devastating effect of commercial deep trawling on marine biodiversity and fish populations.
This 1998 paper examines the impact of bottom trawling generated sediment suspension on the benthic environments of the Gulf of Maine and documents how they are degraded by this activity. Other effects are also explored including habitat alteration that shifts selection to opportunistic species, upsetting the natural balance of ocean floor ecosystems.
This 1998 paper by Kaiser examines the long term significance of bottom trawling on marine environments that are not subjected to long-term fishing activity. Kaiser examines the significance of bottom trawling in the North Sea and concludes that long-term changes are probably restricted to long-lived fragile species or communities found in environments that are infrequently disturbed by natural phenomena. He suggests ways to monitor fishing activity so as to limit the damage done under these circumstances.
