Quick Answer
It is possible to survive for extended periods on a diet consisting of fish and rainwater, but careful planning and rationing are essential to avoid dehydration and malnutrition.
Finding and Catching Fish
In a maritime survival situation, fishing is crucial to obtain a reliable source of protein. Start by observing the water conditions and look for signs of fish activity such as baitfish, schools of small fish, or areas with submerged structures like rocks or reefs. Use makeshift fishing gear like a line made from a piece of fabric or a net fashioned from a life raft material. It’s essential to catch a variety of fish species to ensure you obtain all necessary nutrients. Aim to catch at least 1-2 pounds (0.5-1 kg) of fish per day to meet your energy needs.
Rationing Rainwater
Rainwater is a vital resource for survival, but it must be rationed carefully to avoid dehydration. Collect rainwater using a tarp, a piece of plastic sheeting, or a specialized rainwater collection system. Aim to collect at least 1 gallon (3.8 liters) of water per person per day for drinking, cooking, and hygiene. Ration your water intake to 1/4 to 1/2 cup (60-120 ml) per hour, and make sure to conserve water by limiting your activities to essential tasks only.
Signaling for Rescue
While fishing and rationing rainwater are essential for survival, signaling for rescue is also crucial to increase your chances of being spotted by a passing aircraft or vessel. Use a whistle to signal your location during the day and night, and create a smoke signal during the day using a fire made from dry wood and other flammable materials. If you have a life raft, inflate the bright orange emergency beacon to signal your location. Stay visible by wearing brightly colored clothing or attaching reflective materials to your life raft.
