Fished yesterday&today in Toogoodo&Wadmalaw,bass no trout.Been seeing green flat plastic crates on shell beds,ivestigated today. 2’x2’x6" deep plastic crates with oyster shells in them with tops wired close with hardware wire,some have pvc pipe marking them some don’t. No commerical signs,DNR or DHEC signs. Does anyone know if this is a test for planting commerical oyster beds?
