The invention is a collapsible fishing trap (and a method of its manufacture and use) which is formed from a series of frames, wherein at least some of the frames themselves are constructed from individual lengths which are linked to each other such that they can be pivoted. This is so that the individual frames can be raised and lowered when the trap is erected or collapsed in use. This is advantageous for when retrieving the trap, the relevant frame members effectively collapse upon themselves and therefore can be wound up onto conventional drums that are often used on commercial fishing boats. This also means that relatively long fishing traps can be constructed and practically used while taking up less storage space relative to conventional, fixed frame, traps.
