Fish-class trawler

The Fish class of Admiralty trawlers was a small class of trawlers built for the British Royal Navy during the Second World War.

The vessels were intended for use as mine-sweepers and for anti-submarine warfare, and the design was based on a commercial type, the 1929 Gulfoss by Cochrane & Sons, of Selby. The purpose of the order was to make use of specialist mercantile shipyards to provide vessels for war use by adapting commercial designs to Admiralty specifications.

In 1940 the Royal Navy ordered ten such vessels from Cochrane. All saw active service, and two were lost in accidents. Two vessels, Mackerel and Turbot, were converted for use as controlled minelayers, and were re-named Corncrake and Redshank, respectively.
