Feeding trials continue


Trials are continuing here in Belize.  We are making a direct comparison of early post larval shrimp growth (1,200 per tank @ 25/m2) and survival when fed on AquaMats that are colonized by normal growth vs. allowed to trap suspended sediment in the control structures.  The picture above shows the AquaMats in the control structure (front) and being colonized in still water (rear).  The mats in the control structure fill with algae in a few minutes.  If the shrimp will eat that material and a low cost harvest technique can be found, they can remove a significant proportion of the algae leaving the pond (which is also a significant proportion of the nutrients leaving the pond).  The Uni High prototype could be installed in a similar manner.  We'll project findings from this experiment onto the Uni High findings to estimate yeild and potential viability of strained food sources as feed.  AquaMats are already a known viable food source.

Feeding Trials!


The huge experimental tanks in this picture are being filled as I type this. By the end of the week, we'll be ready to begin feeding trials for shrimp post larvae.

NEED A PROTOTYPE DESIGN!

If logistics are prohibitive, we can just move ahead with Aquamats but it would be nice to get some information from the exact device the club is going to present in Boston.



Inar and I will be running the trials. The interns had a good experience learning water quality etc, but time has run out on their semester.

Hope everyone is having a great spring!

Send us what you can!
