Fish trapping day

Hey gang,

This past saturday 10-26-2013 my group (the fish group) set up our traps for sampling the diversity of fish species on the oyster reefs and some off the reefs. While the B-traps do not produce as much catch as the seine that we used the week before, they did surprisingly well. I was surprised to see how much they did catch. After looking at the hole that the fish had to swim in I had my doubts that they would catch anything. But turns out we did get a couple of specimens, like hog choker, tongue fish, a mullet, blue crabs, and some shrimp. We did have one misshape with trap number eight, the wings that funnel everything into the trap came out of the sediment after a huge barge like ship went by and its wake came washing onshore. While sampling for fish we did take water sample for water quality testing that we worked up back in the lab on campus. Turns out that the samples should be put on ice while in transit, especially for Chlorophyll-a (to keep it out of the sun) and ammonia, which we learned is highly volatile, and needs to be chilled in order to keep the sample from degrading. All in all not a bad day, caught some fish and didn't break the mulle, even though it was smoking pretty good from the extra "weight".
