Doesn the Aquapod have a high drag coefficient compared to other submersible net pens?
Ocean Farm Technologies began drag force testing in November, 2004, with the University of Maine, and these experiments continued with U. Maine in the spring of 2005. In October 2005 The University of New Hampshire conducted a tow test, the results of which have been published and are available at the OFT download site. The lesser twine surface area of the Aquapod (smooth vinyl compared to synthetic woven netting) will have the effect of lessening the drag on the Aquapod wire mesh netting compared to synthetic woven netting. However drag force is directly related to frontal area, thus the Aquapod has more overall drag than more streamlined structures. This larger frontal area, although it produces more drag, also ensures that there will be more water flowage into and through the containment. Since more water will be passing through Aquapods than other net pens, fish will have cleaner, oxygenated water. In addition to water exchange rate, another useful criterion for fish health is the
