you should see how they work, they circle endlessly until they cant find a single oyster left before they move to another spot.
oyster dredging IS as bad and harmful as the gill nets were and it should be outlawed forcing oyster fishermen to go back to less destructive methods like tonging or harvesting by hand

I have touched base with some folks at the LDWF office in Baton Rouge. It seems as if the Commission is likely to decide tomorrow what the oyster harvest regulations on Big Lake will be next year. If the decision is to be made tomorrow, it may be too late to submit comments by email after the meeting.
Therefore, I would recommend contacting Commission members today with your input regarding oystering. Some points to consider:
1. Damage to oyster reefs by dredging not only harms the future of the oyster fishery, but also harms the entire ecosystem and fishery.
2. Healthy oyster reefs provide essential ecosystem services including filtering of anthropogenic inputs, benthopelagic coupling, biological resistance to algae blooms and subsequent hypoxia, nursery areas for finfish, areas of concentrated benthos, and high quality habitat.
3. Over harvesting of oysters was a key factor in the decline of many fisheries along the southeastern Atlantic and Gulf coasts of the United States, including the Chesapeake Bay and Galveston Bay.
4. Scientists estimate that each 10 square meters of high quality oyster reefs produce an additional 2.6 kg/year of finfish and large crustaceans.
