August ecosystem services photo contest winner

Congratulations to the winner of this month’s Ecosystem Services Photo Contest, Duane Fagergren of Calm Cove Oyster Co. 

Under this mat of green macro algae (Enteromorpha sp) lies this year’s crop of yearling single Pacifics. The oysters consume phytoplankton, and excrete feces, pseudo feces, and ammonia in a mixture that serves to fertilize this luxurious crop of seaweed. The lush crop also provides habitat for crab (graceful crabs mostly) and fish (shiner perch, stag horn sculpin, and bay pipefish). The downside of this heavy growth is a mat that makes oysters grow slower, clams come to the surface of the beach and can’t dig themselves back in, and likely oxygen debt as the algae naturally dies and decomposes.

Thank you to all who submitted some great photos this month.

Photos and captions for the next contest are due September 15th. Contest link for details to enter.
