I don't have a dog in this hunt either but here is what it states from the DEC website:
Catch and release means catching and immediately releasing the caught fish without harm. Measuring, weighing and photographing of the fish are permitted as long as the fish is not removed from the water for an extended period or handled in a manner that could cause it harm. Fish may not be placed in a bucket, tub, livewell, on a string or any other holding device. Catch and release angling is only permitted during the open season for a particular fish species. Catch and release angling during the closed season, or for endangered or threatened fish species is prohibited.
Here is the link to the DEC site and then click on "Fishing Definitions"
