The Green Gap

In the Cold War, we feared a Missile Gap was a strategic weakness. Nowadays, we must awaken to the fact that the Green Gap is true strategic weakness: the nations whose economies will thrive in the coming years will not be those with the biggest factories, but those with the most sustainable, efficient, and ecological markets. What we require is a Strategic "Green Reserve" of ecological design to weather the coming changes that both climate and resource scarcity will force on the international economy.

Yabbies? Yes, Yabbies.

I admit that I had written off Yabbies (Australian slang for crayfish) as an aquaponic beastie because of their typical lifecycle. Most crayfish require brackish water during part of their lifecycle - as well as a muddy shoreline - to reproduce, meaning that the breeding of such wee beasties would be more troublesome than it was worth on a small scale. And then I read about Redclaw Crayfish.

Crayfish are kind of cute, they fill in the detritivore section of the menagerie where tilapia are decidedly omnivorous, and algae and phytoplankton are the base of the food chain. There are some good yabby resources from the folks in Queensland, they are apparently reasonably suited for aquaculture, and they can clean up the stuff that falls to the bottom of a fish tank. In short, sounds like a winner.

Mmmmm. Too bad I don't eat em.

More more more!
