Naval trawlers that still caught fish

Did naval trawlers and drifters ever fish while in naval service?

Yes; incidental catches were eaten or shared, while largely civilian crews carried out minesweeping and ASW duties.

Naval trawlers often used equipment similar to their civilian nets during minesweeping and anti-submarine work, so incidental catches were unsurprising. Fish could be eaten aboard, shared within the service, or passed to families. Many vessels retained most of their civilian fishing crews, supplemented by a naval officer and ratings for weapons. At Gallipoli, their low speed against the current made these civilian-derived craft especially vulnerable while sweeping under fire.
