Weatherly's photo shows how a suspended culture of oysters provides ample space for annual kelps and seaweeds to grow on. The kelp sets in the winter and grows at an astonishing rate in the spring, making an underwater forest under the farms. The kelp provides habitat for invertebrates and fishes and is also used by herring to spawn their eggs on. Photo taken in Homer, AK.

Nathan took this photo in June showing a Pacific oyster's Longline beds in Tillamook Bay, OR. Longline oyster beds provide excellent protection from predators for all kinds of sea life. From various types of seaweed to multiple kinds of shellfish, as well as the local jellyfish hangout spot.

Johnny says: "The power of oysters on water quality." His photo depicts how oysters clean the water; the tank on the left before the oysters, the one on the right shows the same water after oysters were added to the same water source. As you can see it shows how they filter and clean.

Weatherly's photo shows Mytilus trossulus. They filter 2-3 liters of water per hour while they feed and respire. Just one 40' x 40' mussel raft stocked at capacity can filter 3 million liters of water per hour. By filtering water mussels have significant positive effects on nutrient and sediment removal from the water column. Some Nutrients are made into the body tissues of mussels that we later eat, the rest is excreted as waste which ends up on the seafloor, helping stimulate the rate of decomposition within the ecosystem. This means bivalves such as mussels have profound roles in controlling boom and bust cycles of seasonal phytoplankton blooms. Shellfish help stabilize marine environments leading to higher overall productivity and diversity of species.
