Prattville High School Amy Boyd's Honors Biology Class at Lanark
March 24, 2009

A seine collects fish in shallow water that are large enough to be stopped by the net.

PHS student pulls a seine to sample the channel catfish.

 
The bottom of the net is held down to keep catfish in the net.

A channel catfish is held for tagging.

Honors Biology teacher Amy Boyd works with a student preparing to tag a fish.

Students carry catfish from the pond to the tables.

Big channel catfish need to be carried with two hands.  The scientific name for channel catfish is Ictalurus punctatus.  Ictalurus means fish cat.  Punctatus means spotted, and the spots are plainly visible on this specimen.

Fish are tagged to develop an estimate of the population.

A Floy tagging gun was used to tag the catfish in the dorsal fin.

 
This channel catfish has a tag and is ready to be released.

Students work to get the fish out of the net and over to the processing tables.

The seine was cleaned by shaking before other fish collection methods were tried.

Some fish sampling efforts require more effort than others.

This big one weighed five and a quarter pounds.

Now there's a pretty one.
