PROBLEM TO BE SOLVED: To provide medium-rise floating fish bank equipment allowing the whole equipment including a sinker to be easily and securely recovered by simplifying the structure.SOLUTION: The medium-rise floating fish bank equipment 1 is recovered after use. The medium-rise floating fish bank equipment 1 includes:the sinker 2 set on the bottom of the sea G； a fish bank body 4 with a float 3； a mooring rope 5 whose one end is bound to the sinker 2 and whose other end is bound to the fish bank body 4 for mooring the fish bank body 4 under the surface of the sea S, which is cut at a predetermined cutting position P when the medium-rise floating fish bank equipment 1 is recovered, and which has binding parts on both ends of the cutting position P； a recovery rope 6 whose respective ends are bound to binding parts on both sides of the predetermined cutting position P of the mooring rope 5, and which is longer than the length between the both binding parts of the mooring rope 5； and a locking rope 7 which can be fractured with the tension of the buoyant force of the float 3 for binding the recovery rope 6 to an area from the cutting position P of the mooring rope 5 to the one end bound to the sinker 2.【課題】 構成の簡素化を図り、シンカーを含む設備全体を容易かつ確実に回収することができる中層浮魚礁設備を提供する【解決手段】 使用後に回収される中層浮魚礁設備１であって、海底Ｇに設置されるシンカー２と、浮体３が設けられる魚礁本体４と、一端部がシンカー２に結合され、他端部が魚礁本体４に結合され、魚礁本体４を海面Ｓ下に係留する係留索５であって、中層浮魚礁設備１の回収時に予め定める切断位置Ｐで切断され、切断位置Ｐの両側に結合部を有する係留索５と、係留索５の予め定める切断位置Ｐの両側の結合部に、各端部がそれぞれ結合され、係留索５の両結合部間の長さよりも長尺の回収索６と、浮体３の浮力による引張力によって破断可能な係止用索条７であって、回収索６を、係留索５の切断位置Ｐと、シンカー２に結合される一端部とにわたる部分に結合する係止用索条７とを含むことを特徴とする中層浮魚礁設備である。【選択図】 図１
