This problem involves the question of survival. What people need most at sea is water, not food. If there is real danger at sea, the first thing to be solved is the drinking water problem, not the food problem. People will die of thirst, but they will never starve to death. So this question has the meaning of "false proposition". As for catching fish and grilled fish, is it delicious to fry, stir-fry or cook? Why should we confine ourselves to baking?

When people go out to sea, they will reserve enough water and food. There will be no problem of survival unless there is danger. In this case, in the process of waiting for rescue, solving the water problem is always the first. Without food, a person can live for 20 days, but without water supply, he can't live for 3 days. So people at sea may die of dehydration, but it is hard to die of hunger.

The most abundant resources in the ocean are fish, including the problem of getting food from animals and the problem of getting water from animals. It's best if you have fishing tools, but if you don't have anything, it's ok to tear clothes into small pieces of cloth as bait. Marine fish are still stupid, and people always take the bait.

Fish eyeballs are rich in water and can be eaten directly. Fish spine contains not only drinkable bone marrow fluid, but also a lot of protein. As for the fish, you can cut it into small pieces, or cross it and squeeze some water hard. You can also take out the internal organs of the fish and drink them. Generally speaking, about 3 kilograms of fish a day can meet the most basic water demand. This can not only get food, but also replenish water.

In short, if you want to survive at sea, you must ensure that the first thing is to drink water and the second thing is to eat. Of course, seawater should never be tried, and urine can be tried.
