Thank you very much for your participation in the Marylanders Grow Oysters Program (MGO) for the 2022-2023 growing season.

We will be sending you regular reminder letters regarding the maintenance of your cages. Initially, we will be sending you weekly letters (like today’s letter) or reminder cards (see enclosed). As the cold weather progresses and cage fouling issues subside, our maintenance letters will become infrequent. As the weather warms in the Spring, we will ultimately return to weekly maintenance letters and cards.

Because the cages are suspended from your dock, it is easy for them to become “out-of-sight,
Out-of-mind”. Routine and simple maintenance of your cages will help to prevent/control fouling, which will allow the oysters to grow more quickly and the cages from becoming too heavy.

When we delivered your oysters, we instructed our volunteers to suspend the cages six inches above the bottom of your creek or riverbed. At mean low tide, please adjust your cages so that the top of the cage is about six inches below the surface of the water. At this level, there is more food and oxygen for the oysters, which will help to promote their growth.


  1. Make sure that your cages NEVER rest on the creek or river bottom. If they do, the oysters can quickly become covered with mud and will smother and die.
  2. In the early stages of spat development, NEVER use a hose or power washer to clean the cages. The pressure of the hose or power washer can kill the spat.


On Sunday when I checked my oysters, there was a fair amount of growth or “fouling” on my cages. Here’s what you should do for maintenance this week:

  1. Actively dunk your cages up and down in the water to remove silt and sediment from the spat so that they don’t smother and die.
  2. Give your cages a quick shake to keep the oysters from growing together.
  3. Leave the cages on your dock for about an hour to let any growth that has occurred dry out and die.
  4. Set a timer so that you don’t forget to put the oysters back in the water. At this point in their development, the spat should not be exposed to the air for more than an hour or so or they will die.
  5. Make sure that your oysters are evenly distributed on the bottom of the cage and put them back in the water.

That’s it for this week. Please call Suzanne at 410-822-9143 if you have any problems with the maintenance of your cages. Talk to you next week!
