Closterium

I am taking a shot in the dark at what the identification of this particular creature is. The closest thing I've came across that looks anything like it,

Closterium is a desmid, a microscopic green algae that occurs in all types of freshwater habitats. Desmids are typically one-celled, though sometimes filamentous or colonial, and are divided symmetrically into semicells connected at a central point. Closterium is characterized by a sickle shape and sometimes contains gypsum crystals.

Pond Construction

These shots were of the ponds out back of the Brunswick Community College Aquaculture Center, unfortunately none developed too well. Obviously, the settings on my camera were wrong. I use a Canon PowerShot S3 IS Digital Camera which normally captures high resolution, widescreen images with great color, but not this particular day. I'll try in the next days to capture some color corrected shots of the BCC ponds. I felt this is important, regarding my last post on Aquaculture Myths, such as the realities "Running a fish farm requires hard physical work and can be stressful," "Farming is the best background for getting into fish farming. Basic farming skills like operating a tractor, equipment repair, and welding are needed," and soforth.
The size of land to accomodate such ponds and the labor involved is intensive and insight into what's involved with an Aquaculture operation. Dr. Holland (BCC) expressed a bit of humor with the people who presume they'll build (and/or start) a fish farm in their backyard. It simply doesn't work that way as you can see from these shots.







Here are the better photographs, as promised!
