I have a friend who got an aquaculture permit at one point. He was not actually running a commercial set up. I think it mainly had to do with inspection of the site to make sure that the species could not escape or be easily released into the wild. Stuff like the location being above flood plain and fencing to keep people from steeling/releasing the animals and/or the tanks being in a secure building. The drains having a certain size mesh so water changes can't release animals to the wild and stuff like that. I believe the permit was also needed to transport restricted species. I do have to wonder if redclaw really can be grown 250 adults in an 8 foot diameter tank. I would expect them to be too territorial for high density without cage layers and hides. I thought all crawfish like creatures were territorial.
Less than $20 apiece but expensive nonetheless. Very interesting.
Small Breeders 4" - 5" are $5.25 Each
Packed 18 to the box
Ratio: 6 Males / 12 Females
Nope. These sp are not aggessive. They can and do walk around on eachother. The lady said they are easy to keep in these tanks... Considering their $20 a pop, thar could be a viable option.
I've heard of people culturing the giant tiger prawns under the rafts in large raft bed systems. Those again would require a permit and need warm water but they don't try to escape they way local crays would.
Well, Friendlies did try the tiger prawns in their raft beds. They found that they didn't manage to harvest enough of them to make them really salable. I mean can you really market a product that you only manage to harvest about one meal for a family a year? Keep in mind that you probably only get to raise about one prawn per meter squared of raft.
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.
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.
