Guess where I'll be cast-netting on the weekends. The river is only 2 miles from the house. According to the locals, these Dasyatid rays are caught fairly regularly from mid-summer to mid-fall. Not bad for being 2 1/2 hours from the beach.
It's considered "cold-water' in that it doesn't require the higher temps of a tropical environment as is the case with most south american riverine rays. Normal range for these rays is around 59-72 degrees F.
