This idea of using “fuzzy rope” is a bad idea because though it is cheap it is made of plastic. Plastic photo-degrades in sunlight and its particles get so small they are impossible to retrieve from the water. We still do not know the long-term ramifications of making this ‘toxic soup’ because plastic is such a new material but we do know that it leeches toxins indefinitely and has been found in not only the stomachs of smaller fish but has made its way up the food chain. In fact tiny particles of this photo-degraded plastic have been found in the center of tumors and in the flesh of human fetuses.
In addition this method was developed for mussels not oysters. Mussels have tensile threads that allow them to cling to objects for up to 2 years but are not reef makers like oysters. Oysters grow by cementing their shells unto other oyster shells making them the backbone or structure of the reef.
Adding vast strands or wads of plastic or “fuzzy rope” adds a third problem to the mix which is it would pose a navigational hazard for boats in the area. I could go on, but, really why? Fuzzy rope is the worst idea I have heard of yet and unfortunately it is all over the media…nobody working on this had any ill intentions the same way that the inventors of plastic thought it was a new dream. Its just that plastic should never be put in water this way.
