How to preserve catch on a life raft for extended periods?

Storing Catch on a Life Raft

When preserving catch on a life raft, it’s crucial to gut and clean the fish immediately to prevent contamination and spoilage. Use a sharp knife or sharp object to make a shallow cut along the belly of the fish, then make a second incision from the anus to the gills, taking care not to puncture the stomach or intestines. Remove the guts and gills, and rinse the fish in seawater to remove any remaining bits of flesh or blood.

Cooling the Catch

To keep the fish cool, store them in a shaded area of the life raft, away from direct sunlight and heat sources. Use a tarp or plastic sheet to create a makeshift awning, and place the catch in airtight containers or sealed plastic bags to prevent moisture from entering. If possible, use a small amount of ice or even just a cold, wet cloth to keep the catch cool, but be sure to replace the cloth regularly to prevent the growth of bacteria.

Signaling for Rescue

While preserving catch is essential for long-term survival, signaling for rescue is also critical. Use the preserved fish as a food source, but be sure to reserve some for signaling purposes. By saving the fish heads, which are high in protein and can be used to make a strong-smelling signal fire, you can attract the attention of potential rescuers. Additionally, use other items on the life raft, such as mirrors, flares, or brightly colored clothing, to signal for help.
