Abstract: A method for naturally culling mussel population on a mussel-culture rope, comprising the steps of installing a predator guard around the mussel-culture rope; and during the step of installing, adjusting a degree of mussel protection of that predator guard. In one aspect, the step of adjusting comprises the steps of opening and adjusting a size of a breach in the predator guard. In another aspect, the predator guard is made of an elongated hemicylindroidal mesh-like element with an open side. The hemicylindroidal element has flaps bordering the open side. The flaps constitute duck-mobility impediments for limiting without completely precluding predation by diving ducks.

Abstract: The mussel culture rope is made of interlooped hitches providing hollows, crevices and cavities for sheltering young mussels against predators and for providing extended attachment surface to retain growing mussels. The loopwork is a recyclable type loopworks having a fixed knot at a starting end thereof and a releasable knot and a loopwork release segment at a terminal end thereof. The loopwork is recycled into a plain rope during harvest and braided again for a subsequent culture cycle.
