Meaning and Definition
A type of fishing trawl net that is held open horizontally by a rigid beam or metal frame, rather than by otter boards (doors). It is designed to be dragged along the seafloor to catch bottom-dwelling fish and shellfish.
The term can refer to the fishing gear itself, the method of fishing using such gear, or the catch obtained from this method. In a broader technical context, it may describe any towed sampling device used in marine biology or geology that uses a rigid frame to maintain its opening.
Dialectal Variation
British vs American Usage
Differences
The term is technically identical. However, in the UK/EU context, its use is heavily regulated due to concerns about seabed damage, making it a frequent topic in policy discussions. In North America, 'beam trawl' might be used more specifically for certain inshore fisheries (e.g., for shrimp or flounder), while 'otter trawl' is more common for large-scale offshore work.
Connotations
In environmental and conservation circles, the term often carries negative connotations due to association with habitat destruction (scouring the seabed). Within the fishing industry, it is a neutral technical term for an effective, if sometimes controversial, tool.
Frequency
Low frequency in general English. Its use is almost entirely confined to technical reports, fishing industry publications, environmental science, and fisheries management contexts.

FAQ
Frequently Asked Questions
No, it is not universally illegal, but it is heavily regulated in many regions (like the EU) due to its environmental impact. It may be banned in specific marine protected areas or sensitive habitats.
Primarily bottom-dwelling (demersal) species such as sole, plaice, shrimp, prawns, and various flatfish. It also catches significant amounts of non-target species (bycatch) and disturbs the seabed.
It is controversial because the heavy beam and tickler chains (used to scare fish into the net) can physically scour and damage the seabed habitat, harming corals, sponges, and other bottom-dwelling life, reducing biodiversity.
'Trawling' is the general method of fishing with a towed net. 'Beam trawling' is a specific type of trawling where the net is held open by a solid beam, as opposed to 'otter trawling' where doors are used.
A type of fishing trawl net that is held open horizontally by a rigid beam or metal frame, rather than by otter boards (doors). It is designed to be dragged along the seafloor to catch bottom-dwelling fish and shellfish.
