otter trawl
C2Technical, Maritime, Fishing Industry
Definition
Meaning
A large, bag-shaped fishing net dragged along the sea bottom to catch fish and other marine life, using otter boards (trawl doors) to keep its mouth open.
The entire fishing gear system (net, otter boards, warps/cables) used for bottom trawling. By extension, the practice of using this method and, sometimes, a vessel equipped for such fishing.
Linguistics
Semantic Notes
Specifically refers to bottom trawling with otter boards, distinguishing it from beam trawls, midwater trawls, or pair trawls. Often used as a compound noun. The method is sometimes criticized for environmental impact.
Dialectal Variation
British vs American Usage
Differences
No significant differences in core meaning. UK English may more commonly use "otter trawling" as the activity; US usage might more frequently specify "bottom otter trawl".
Connotations
In both varieties, the term has strong industry/technical connotations. In environmental discourse, it often carries negative connotations regarding seabed damage.
Frequency
Equally low-frequency in general language. Slightly higher frequency in coastal communities and news related to fisheries in both regions.

Learning
Memory Aids
Mnemonic
Imagine an OTTER swimming ahead of a TRAWL net, using its flat, wide body like the otter boards to push the net's mouth open.
Conceptual Metaphor
THE SEA IS A FIELD (to be harvested). The trawl is a harvester/plough combing the seabed.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate "otter" literally as "выдра". It refers to "otter boards" (траловые доски).
- "Трал" alone is a correct translation, but the specific "otter trawl" is often just "донный трал" (bottom trawl) or specified as "трал с траловыми досками".
Common Mistakes
- Using 'otter trawl' to refer to any fishing net.
- Confusing it with 'travel' in speech due to phonetic similarity in some accents.
- Thinking it has something to do with the animal otter.

FAQ
Frequently Asked Questions
Not exactly. 'Trawling' is the general activity of fishing with a dragged net. 'Otter trawling' is a specific type, usually bottom trawling, that uses otter boards (doors) to spread the net open.
It's named after the 'otter boards' (also called trawl doors). These are large, flat, wooden or metal panels that, when towed through water, splay apart and hold the net's mouth open, similar to how an otter's flat body moves through water.
Primarily demersal (bottom-dwelling) species like cod, haddock, flounder, sole, shrimp, and scallops.
Yes. While efficient, it is often criticized for damaging seabed habitats (like coral and sponge grounds) and for high levels of bycatch (unintended catch of non-target species), leading to calls for restrictions in vulnerable areas.
