Cleaning, Bleeding and Chilling a Fish
The difference between a good eating fish and a spoiled one is mostly the first ten minutes: stun, bleed, gut, chill, and keep it cold from there.
This is for educational purposes only. Not professional medical, electrical, or safety advice.
Warning
Do not leave a caught fish in the sun or a warm boat: perishable seafood should not sit out beyond 2 hours, or 1 hour above 90°F/32°C. Cook most fish to 145°F/63°C internally.

Stun, then bleed
A sharp, accurately placed blow just above the eyes is a recognized percussive stunning method, and brain spiking requires species-specific anatomy and far more precision. Oregon State University Extension recommends a heavy blow to the head followed promptly by bleeding, gutting and chilling. Do not rely on letting the fish suffocate.
- 02
Gut without rupturing the gut
Open the belly carefully, remove the viscera, clean the body cavity and remove residual blood. Avoid puncturing the intestines and smearing their contents over the flesh.
- 03
Keep it clean and keep it separated
Use clean equipment and potable water, and keep raw fish apart from ready-to-eat food, the same rule that applies to any raw meat.

Cold is the whole job after that
FDA's guidance for fresh and frozen seafood is to refrigerate at 40°F/4°C or below and use within 2 days or freeze, and not to leave perishable seafood out for more than 2 hours — or 1 hour when it is above 90°F/32°C. An off-grid setting does not suspend those microbial limits.
- 05
Cook it to temperature
FDA's guidance is to cook most seafood to an internal temperature of 145°F/63°C. A thermometer is cheaper than food poisoning.
- 06
Handle uncertain catches gently
NOAA's guidance for fish that might be released is to minimize handling and not to lift them by their gills or other vulnerable parts, and a landing net beats dragging an uncertain catch across rocks.
