FROZEN FISH
There’s much debate within the fishing community over the ethics of fishing during specific times of the year and targeting fish during critical points in their life cycles.
REMOVE GLOVES
It’s best to remove any kind of glove and wet your hands before handling a fish, for a photo or otherwise, as cloth is extremely adept at removing the protective slime layer that shields the fish from harmful fungi, bacteria, and ectoparasites.
KEEP YOUR HANDS WARM
When fishing in cold or below-freezing conditions, consider carrying a small microfiber towel tucked in the front of your waders. When your hands get wet or fish-slimy, just dry them off, warm them up inside the upper chest of your jacket, and keep fishing, or replace the glove you took off to handle that fish.
