Ehow taught us how to raise crayfish. We think the problem is that we have too many crayfish and not good enough filtration. So tomorrow we'll take a trip back to the river and release some of the crayfish. We have enough calcium in the water we think.
Wiki-how taught us that crayfish are excellent escape artists and the males are bigger than the females.
On a side note: the lad is writing a book about Kale the Crayfish. It has pictures and drama in it. It's quite interesting. At our family dinner today everyone had to read it. :) I love it... the lad wants to spell words and he's learning to write it all down and do his punctuation and everything. :) VERY COOL. :)
I'll have to let you read it at some point, it makes me smile.
We needed to do some research for it as well as there is a villain...the LOBSTER!
Here's one place we stopped at. SLGO.
Here we learned that lobster can get up to 1.8 metres long (time for some impromptu math). :) The lad was suitably impressed. The image below is from that site.
