Mainly shrimp

For this week, I've mainly been focusing on the shrimp. So far this week, I've been regularly feeding the shrimp, feeding the fish, and watering the hortensis. We have already found out that the Vsep water is unsuitable for the shrimp and will be using it for just the Talapia and for some irrigation experiments on some newly planted lentiformis and Attriplex hortensis within the greenhouse (and possibly some bio-assay on some bigger shrimp.)

We've also noticed that a lot of the shrimp in the RO concentrate tanks have been dying. So we ran a bio-assay using RO water and 3 ppt artificial sea salt water with the shrimp. The first time we found that 3-4 had died out of the 10 put in. -However, about 3 of them were stuck on the side of the beakers indicating that they were startled somehow and jumped; so we suspected someone had come in and disturbed them and they got scared and jumped. So we re-did the bio-assay experiment, and found that within 24 hours, none have died. And within 48 hours, 1 had died.

I also went down to Marana this week. There, I helped collect moisture data on the pre-planted plants there using the neutron probe. After that I helped out by cutting back some of the plants there to make the place look nicer.

As of now, the Attriplex hortensis have grown quite large. We have been measuring the height of them weekly just to get a growth rate for later, and you can already see that the hortensis grown under the RO treatment + aquaculture has grown much larger than the others. The regular RO treatment and fresh water are almost the same, (but the RO water treatment are growing slightly more.)

So far it's been good. Next week we will probably set up the Talapia in RO and Vsep water for a bio-analysis and possible growth experiment.
