This young man is very proud of the sand perch and other fish his dad caught at Big Pass, South Siesta. The perch is about 8" long. (We're not 100% certain of the ID. )These fish are found from inside waters, bays and channels all the way out to open water, usually along open or patchy bottoms. The sand perch has both male and female organs all at the same time, i.e. it is a hermaphrodite.
