More from work...

Thought I'd post a few more pictures of some of the field work that fisheries biologists sometimes do. Then I'll promise I'll leave well enough alone for a while and get back to 100% kids! Again, we're on Leesville Lake. This is a shot from the boat launch in the morning right after most of the 'steam' had burned off.
We're still looking for catfish, just like in the previous gill-netting pictures. Now we are running trap-nets. Zooming off to the first net...
This is a trap-net. Hard to describe, so I hoped a picture would help. A lead runs perpendicular out from shore, like a fence of netting material. It funnels fish to the wings, these are the parts stocking out each side in a triangle shape. The fish swim further into this mess and eventually get caught in what basically amounts to a series of large minnow-trap type contraptions...
This is a trap-net getting 'run', as we call it...checking it for fish. We set these traps on a Monday, usually, and then check them each subsequent day until we are done. They are left in the lake the whole time. This is our boat tethered up to a trap net getting ready to take fish out.
This isn't one of the catfish we were looking for, but we got a nice 15.5" black crappie in our nets today. For those who fish, you'll appreciate this. For those who don't, this is a fairly large crappie.
