<p><br/>I actually like the idea since it adds more diversity but I kinda doubt many "commercial" ventures would find it all that profitable. I think it would be great for a large home or community size system but I doubt many of those in the USA would be able to get the prawns (due to the permitting) or they will be in a cooler climate and might not grow as big in a season. What one could grow would probably still only be enough for one special meal or something. But those are the sort of celebratory things that add real spice to life sometimes.</p>

<p>I don't know how hard it really is to get the aquaculture permit but seems to me you would have to get inspected and I believe they want the site fenced to keep people from releasing the animals into the wild. It would cost probably something like $100 a year. Miami Aquaculture and other places I know of will require proof of the permit before selling the prawns to you.</p>

<p>Now I don't know if there are any other edible smaller shrimp species that might be native but it seems to me that might be a better way to go but I don't know really.</p>

Well, I have experimented with this. The florida crawfish i caught enjoyed water not more than 2 ft high, plenty of decaying leaves from the lake then died of cold. Before the cold, it was fine. I didnt give it enough warmth. I will let you know how my next one goes :P My goal for this next attempt will be to build a small rice field.

I've also been looking at more local versions. Looks like the blue electric crays that you get at the LFS are just a blue version of the common red swamp. Agressive, yes. Doable, we'll have to see.
