When surviving at sea, conserve all emergency supplies of food and water until you really have to use them. And even then spend them as sparingly as possible, trying to live on food and water extracted from the environment.
Survival at sea, fishing, catching fish and birds, collecting algae and crustaceans, preserving food supplies.
When surviving at sea, fish will be the main source of litany. There are poisonous and dangerous representatives of the marine fauna, but in general, fish caught in the open ocean outside the land visibility zone is safe. Closer to the shore there are fish that are dangerous both in themselves and poisonous as food, including such as snapper and barracuda, which are safe to eat under normal conditions, but their meat is poisonous if they are caught near atolls or reefs. Flying fish can even accidentally fly into your boat.
or if there is a moon in the sky, dip a piece of cloth, foil or metal into the water that reflects moonlight, which could also lure possible prey. Make homemade hooks from any available materials: small folding knives, metal scraps, wire. Small shiny metal objects buckles, spoons, coins can serve as bait.
When using a metal spoon or other spoon-bait, try to keep it in motion by pulling and bleeding the forest. Use entrails, trimming caught fish as bait. Fish quickly deteriorates and must be eaten freshly caught in the tropics, unless the air is dry enough, which is unlikely in the tropical ocean. In cooler climates, excess fish can be dried in the sun and stored in stock.
Catching birds while surviving at sea.
Birds at sea are also potential food. A watercraft can lure them, as a potential perch. Do not move until they are seated, and you may be able to grab prey, especially when the birds are tired of flying in bad weather. Birds can also be caught using a fishing line launched with water with a hook or its home-made substitute with fish bait. Fishing tackle from a diamond-shaped piece of tin, wrapped in fish and drifting next to the boat, being tied with a rope, will attract birds. When the bird grabs the fish, the gear should be stuck in the esophagus.
Algae harvesting at sea survival.
Algae are found not only near the coast, but also in the open sea, there are their floating forms. For example, Sargasso algae in the Sargasso Sea and the North Atlantic Current, and other algae found in the colder waters of the southern Atlantic and Pacific oceans. Since algae are hard and salty, they are poorly digested raw. They require a lot of water, so you should not eat them when there is little water.
Algae can also be a source of food in the form of small crabs, shrimps, crustaceans that live on them and small fish that can be shaken out of the algae caught next to the boat. These small decapods have spotty brownish tones, the color of algae, so it’s not easy to notice them. Plankton from water can also be a useful food source, especially in cold waters..
Make a cat by tying pieces of wood or metal in such a way as to make a hook or anchor, with several horns. Tie such a cat to a rope and drag it behind the boat or throw it to catch algae. It can also be used to collect floating debris and other items useful for, for example, repairing a makeshift raft..
