Readings for Week 6: Shellfish and the Ecology of Scale

This week we will use the lens of Puget Sound to look at issues of shellfish biology and ecology relevant to the culture of clams, mussels, oysters, and geoducks.

Tuesday, May 5

Today we will concentrate on the issue of carrying capacity, which you should read about in Christopher McKindsey et al.'s article on Carrying capacity models and shellfish culture. Also please read the chapter by Dr. Joth Davis on an industry perspective in the book Shellfish Aquaculture and the Environment. Then we will look at two examples of environmental concerns with shellfish raising, which involve carrying-capacity issues. In class, we will discuss fieldwork logistics along with these controversies, and try to draw general conclusions from them.

Thursday, May 7

Today, unfortunately, I won't be able to come to class, but you will use the lens of shellfish to consider the ecology and economy of Puget Sound.

Begin by looking at parts of Puget Sound Partnership's 2013 State of the Sound Report (once again, as with the state of the world's forests, the 2015 report isn't out yet). It is long and detailed, but contains a lot of useful charts and tables. Please read over the Introduction and the chapter on performance management, and then skim through the vital signs section, looking especially at those vital signs indicators and targets in the sections on water quality, healthy human population, and habitat that are particularly relevant for shellfish production (you should know by now what they are). After you have done this, but by 9:30 a.m when the class would have met, please post 200-300 words on why you think the various initiatives to restore Puget Sound have made so little progress. My comments on your posts will have to take the place of class discussion.

You should also watch a fun video that will be a preview, in some ways, of our Saturday trip.
