Quick Answer
To clean fish before smoking, gut and gill it, and rinse with cold water to remove blood and slime, then pat dry with paper towels to prevent bacterial growth.
Pre-Cleaning Preparation
Before cleaning the fish, make sure to have a clean and sanitized workspace to prevent cross-contamination. Wear gloves to protect yourself from fish juices and bacteria. Have a sharp knife or fillet knife ready for efficient gutting and filleting.
Cleaning and Filleting Techniques
Start by making a shallow incision along the belly of the fish, then cut from the anus to the gills to remove the guts. Rinse the fish under cold running water to remove any blood or slime, then pat dry with paper towels, inside and out. Remove the gills and gill rakers, and trim any bloodlines or dark meat. For whole fish, make a shallow incision along the spine to allow for even drying and smoking.
Drying and Preparation for Smoking
After cleaning and filleting, lay the fish on a wire rack or tray, skin side down (if filleted) or belly up (if whole), and let it air dry in a cool, well-ventilated area for 30 minutes to an hour. This allows the fish to dry and develop a tacky surface that will help the smoke adhere. Before smoking, make sure the fish is dry to the touch and has a tacky surface, then proceed with your preferred smoking method.
