PROBLEM TO BE SOLVED: To provide an underwater floating fishing bank to which a ROV (remotely operated vehicle) can, firstly, simply be carried to an underwater floated fishing bank without metal fittings for recovery and in which a recovery rope is, secondly, hardly rubbed or entangled with the underwater floating fishing bank or a mooring rope； and to provide a method for recovering the same.SOLUTION: An underwater floating fishing bank 1 which is moored to a sinker built on the bottom of water through a mooring rope in a floated state in sea water is characterized in that a recovery rope 5 whose one end is connected to the mooring rope and other end is connected to the lid portion 22 of a recovery rope-receiving box 2 set to the upper portion of the underwater floating fishing bank 1 and is at least approximately extended to the sea level is received in a recovery rope-receiving box 2, and a portion 22a to be latched is disposed in the lid portion 22. Therefore, when the underwater floating fishing bank 1 is recovered, the latching portion 81 of ROV8 latches the portion 22a to be latched of the lid portion 22, and the other end of the recovery rope 5 including the lid portion 22 is carried to a working ship, and then the recovery rope 5 is wound up.【課題】第１には回収用金具を使用せずにＲＯＶ（遠隔操作探査機）を水中浮魚礁まで簡単に運ぶことができ、第２には回収索が水中浮魚礁や係留索に擦れたり絡まり難い水中浮魚礁およびその回収方法を提供すること。【解決手段】この水中浮魚礁１は、水底に沈設されたシンカーに係留索を介して海水中に浮遊状態で係留されるもので、一端がその係留索に連結される一方、他端が水中浮魚礁１の上部に設置された回収索収容箱２の蓋部２２に連結され、少なくともその他端がほぼ海水面まで延びる回収索５をその回収索収容箱２の中に収容しており、蓋部２２には被掛止部２２ａが設けられている。そのため、この水中浮魚礁１を回収する際は、ＲＯＶ８の掛止部８１を蓋部２２の被掛止部２２ａに掛止して、蓋部２２も含めて回収索５の他端を作業船まで運び、その後回収索５を巻き上げる。【選択図】図５
