Baby Shrimp

This week has been fun. I first got to go down to Marana again and we collected some Talapia from the tanks over there; we also mixed in some fertilizer into the soil bed that we set up over there last week. After that I helped cut back some of the plants over in Marana, to make the place look a little nicer -because people were gonna visit soon.

I have also been keeping up with the Attriplex hortensis waterings, and have been feeding the fish regularly. The fish we got from Marana, Desiree and I weighed, measured, and then put into the greenhouse fish tank (so we can do some growth analysis later, and to add plant nutrients to the water.)

Also this week, I went down to the U of A veterinary building (over on the freeway) with my mom, and we picked up some baby shrimp for the shrimp tanks. We caught about 150 shrimp and I took them back into ERL and put 10 shrimp into each tank. We also set up a bio-assay for the shrimp using the Vsep water and 20 ppt artificial sea salt water. (After one day 50% died in the Vsep, and 0% died in the 20 ppt.) -Good thing we decided to not use the Vsep for the shrimp...

We have also noticed that some of the shrimp in the RO concentrate tanks are dying, so we will probably do a bio-assay for the RO water too.
