What ever happened with the freshwater prawn project?
I am also interested in prawns.
I am curious as to what happened too!
I suppose you decided not to grow the freshwater prawns (Shrimp) after all?
One of the only ways to fit them into an aquaponics grow system is to use cages in the tanks.
Since the prawns like the bottom of the tank, you can also grow tilapia in the same tank.
You were correct that Prawns are highly territorial - which is why the aquaculture prawn farms use netting (baffles) to essentially mark territories... In Thailand there is a few growers who are actually using cages (I understand that there is also at least one farm in Florida using cages as well - but haven't been able to track it's source down).
I agree with you assessment that "Prawns are tasty little critters", my wife and I both like them. Apparently the people in the grocery stores keep snatching them up as well (Over 90% of the large shrimp sold in the groceries are fresh water prawns. Shrimp is so fished out in the oceans/seas that they are essentially small - very few large shrimp are actually harvested from the seas.)
My apolologies. Been a little busy and off this site. Probably need to catch up with a lot of folks particularly those good people on the east side of Phoenix who gave me some tilapia some months ago. The preliminary experiment actually worked. Just working on how to properly release the information. In the mean time, I will be teaching my next backyard intro to aquaponics overview class on December 21, 2011, 5:30 pm to 7:00 pm. The location is the Home Grown Hydroponics Store at Broadway Rd and McClintock in Tempe Arizona. Here is the URL: http://www.homegrownhydro.com/classes.php
If you can make it, please rsvp at RSVP1@nxthorizon.com or for those on facebook, this link:
I lost track of this theory for some reason...Any who...yeah I'm kind of off the shrimp because they seem difficult to get in small amounts. But if someone else found a way I'd try some. Really sound like fun.
I'm still planning to grow Talapia, but at least a year before I'll have time to build a pond.
Regarding getting Macs in small amounts, I'm working on that. Will take a few months though.
any new updates?
Very interesting thread. Don't think I read the entire thing last time I posted. I'm curious now how to introduce prawn into my own plans.
I guess you were talking about Prawns when you were referring to Fresh water shrimp a couple of years ago when you started this thread. Would that be macrobrachium rosenbergii (may be mis spelled). I am working on putting together a project in St louis as we speak with both Prawns and Talipia in an aquaponic system in greenhouses. I would love to here what you guys have learned since you first started talking about this back in 2010. What is the largest size tanks you have used so far? and what about canabalism or lost ratio with the Fresh water prawns, are you using pumps to move the water and how deep or your indoor ponds???? thanks
