Prawn Update Post
So, you may be wondering ... How are those Macrobrachium rosenbergii doing after a month in FC's classroom RAS?
The prawns arrived on March 19. At that time, the biggest one I measured was around 5 cm, tip of telson to tip of rostrum.
(I'm not measuring long delicate claws or antennae.)
This guy is a solid 7 cm and he's not the biggest, just an average size prawn who was slow enough for me to net him.
(He's alive by the way, and was returned immediately to the RAS.)
There is a huge alpha male BC (blue claw) living under the biofilter in the tank. The students have named him, "Goliath". He's got a centimeter or two on the photo model prawn above.
They are great fun and the kids are getting the basics of recirculating aquaculture systems down just by working with them.
Today, if they don't make me cover an absent teacher's class during my planning period, (where have all the substitute teachers gone? Isn't there a job shortage out there?), ... where was I? Oh yeah, ... IF I actually have a planning period today, I am inviting the TMH (trainable mentally handicapped) kids and their teachers into my empty room and we are going to feed the shrimp, feed Stewie the best snake ever, and look at the fish and critters in my aquariums.
I like to include them whenever I have something neat going on. We've tried to do this for a few weeks, but every time I picked a day, I got called to cover a class.
Hopefully I won't have to break our date this afternoon.
