How to Choose a Fishing Cooler

For an angler, a cooler does two jobs: keeping food and drinks cold, and keeping the fish you plan to eat cold enough to stay firm and fresh. This guide covers the cooler types, what to compare, and how agencies say to ice your catch. We have not tested coolers against one another and prices move, so we name no models; compare current ranges on the makers’ own sites.

Cooler types

• Hard coolers: a rigid insulated box with a lid, from heavy-walled boxes with gasketed lids to lighter, cheaper ones; compare what each maker states about wall build and ice holding.
• Soft coolers: lighter and easier to carry to the bank or fit in a kayak, usually for shorter trips.
• Insulated fish bags: flexible, zippered bags that lay long fish flat and fold when empty.

What to compare across any type: how much ice it holds for your trip length, how well the lid seals, whether the drain is easy to open, and how heavy it is full. If you can, keep one cooler for food and drinks and a separate one for fish.

Ice: chipped for fish, block for drinks

Wyoming Game & Fish’s advice for anglers keeping fish, especially when air or water is above 40 °F:

1. Fill a cooler with lots of ice. Chipped ice is best; block ice may keep drinks cool but won’t keep fish cold.
2. Dispatch fish as soon as they are caught.
3. Add a little water to make an ice slurry, and slide fish under the ice into the slurry as they come aboard. Keep adding ice.
4. Remove guts and gills during a lull in the action, then put the fish back in the slurry.
5. Keep fish ice-cold until you cook or package them. On the road, pack them in another cooler, each well covered with ice and with ice in the gill and gut cavities.

Bleeding and slurry (FAO)

The UN Food and Agriculture Organization’s handling guidelines for trap and pot catches in tropical waters advise bleeding fish as soon as possible after capture, which reduces discoloration, bruising and the start of spoilage; fish can be bled in an ice slurry. Its best slurry for sea fish is four parts freshwater ice to one part seawater, kept as close to 0 °C as possible but not below. It warns against adding salt (which lowers the temperature and partly freezes the fish) and against leaving fish in the slurry too long, which can bleach skin and cloud eyes.

A stringer or the cooler

Connecticut DEEP suggests keeping fish on a stringer in the water while you fish, or better, putting them straight on ice in a cooler.

Keep it legal and safe

• Size, bag and possession rules apply to the fish in your cooler. Your state may also say how fish must be kept until you get home (for example whole or measurable), so check before you fillet on the water. Our fish weight calculator helps estimate a fish’s weight from its length.
• Consumption advisories: New York DEC reminds anglers to check fish consumption advisories for the water they fish; most states publish them.

Care

Rinse and dry the cooler after each trip so it doesn’t hold odours, and store it with the lid open until fully dry. If a fish such as largemouth bass is going back, keep it in the water instead; see our catch and release guide.
