Catch 22 species of fish - but both micro and standard species count, you get 1 point per 3 full species (1-7 points) and then +3 for getting the 22nd species. Photograph all. (1/2/3/4/5/6/7/10 pts for getting 3/6/9/12/15/18/21/22 species). Micros will only count if they are VERY OBVIOUSLY a unique species. Don't expect to get full credit for submitting a set of identical minnows - each must have a visible characteristic in the photo that lets you key it to species. Please describe the characteristic used for ID in the comment text of your entry. You need to target species that can be easily distinguished in a photograph with no ambiguity and no locality info needed. Darters are probably not a good choice unless you can catch males with ironclad ID features; of course some are better than others (blackside, logperch, etc.). Obviously standard-size species are much easier to ID so they should make up the backbone of your entry.
THERE IS NO DEFAULT CHALLENGE THIS WEEK SINCE IT IS ALREADY A SPECIES TALLY!
