Super-trawlers: what they take and leave behind

I WISH to respond to the letter from John F Murray headlined ‘Ban the ocean floor sweepers’ (Irish Examiner, November 13).

Mr Murray should be brought up to date with modern fishing practices.

Super-trawlers generally spend four to six weeks at sea and freeze and ‘carton’ all their catch — they do take the smallest sprat but these are also frozen in blocks.
