Fw: [andorprojex] Digest Number 3081

Just a quick note about using fish tanks as thermal mass for a greenhouse:
1. There are very few food fish that can thrive in warm water (above 20C) - low oxygen solubility
2. Even fewer that will grow well with fluctuating water temps
3. Thermal mass is usually designed for high heat (sensible heat = temperature change) flux which contradicts both 1 and 2 above.

As for which species, if tilapia are allowed in your area ( very invasive species) they are an excellent start. Tolerate extremes of temperature, low oxygen, high nitrogen, etc. Almost impossible to kill. Hence why they are so invasive. They will survive in a mud puddle. Very easy while figuring out your system. They will eat anything from algae to pig poo. Thai farmers raise pigs over the ponds for this reason. Just don't let them get out.

There is a very good text book on Recirculating Aquaculture Systems (RAS) that should answer all your questions. I can dig it out if you want the author, but just search RAS and/or Amazon and see what you find.

Hope that helps some.

» Scientists and journalists seek to educate public

» Scientists and journalists seek to educate public: Scientists speak to each other in complexities, while journalists seek to tell stories simply.

Yet the two need to find common ground to help the public understand scientific and medical topics accurately –especially in a world in which science often becomes politicized and scientific funding can depend on public perceptions.

The two groups came together last week at USF to try to find common understandings at a forum at USF, convened by Research! America, USF and Pfizer.

What is Ethnography? :: Homepage of Brian A. Hoey, Ph.D., Anthropology

What is Ethnography? :: Homepage of Brian A. Hoey, Ph.D., Anthropology: The term ethnography has come to be equated with virtually any qualitative research project (e.g., see Research Gateway) where the intent is to provide a detailed, in-depth description of everyday life and practice. This is sometimes referred to as "thick description" -- a term attributed to the anthropologist Clifford Geertz writing on the idea of an interpretive theory of culture in the early 1970s (e.g., see The Interpretation of Cultures, first published as a collection in 1973). The use of the term "qualitative" is meant to distinguish this kind of social science research from more "quantitative" or statistically oriented research. The two approaches, i.e., quantitative and qualitative, while often complimentary, ultimately have different aims
