Weve tried foam pool noodles before going with the same coated mesh we use to build our cages. And we dont get mad. An unwieldy cage poses the risk of crew injury or boat damage. Oysters grown in coated and uncoated bags placed in cages flipped biweekly and triweekly had similar survival, growth, weights, and condition index.
