Kids Fishing Photo Contest

It certainly isn’t hard to “ picture it”, that is – smiles, laughs, looks of anticipation (期望) and excitement. So, join in the fun, catch the excitement of your child on film while fishing and enter his or her picture in the yearly Kids Fishing Photo Contest! The contest is sponsored by Virginia Department of Game and Inland Fisheries (VDGIF) in celebration of National Fishing Week!

The winning pictures are those that best catch the theme “kids enjoying fishing”. Children in the first through third place photographs of each category will receive different fishing-related prizes. Winning pictures will also be posted on the VDGIF website and may be used in all kinds of VDGIF publications. There is no need to be a professional photographer. Any photo will do.
