Can You Live On Just Fish?

Question

I am doing a report on survival and this is a main topic for mine. If you have to live on a river, can you survive off of just fish?

Answer 1

nope beacuse i dont like fish or any other kind of sea food, therefore i would rather eat plants or starve so i would t make it

Answer 2

No you cannot live on just fish.

  The problem is that there will be a deficiency of vitamins such as C that is found in fruits and vegetables. Too much protein can cause problems as well. There may be a lot of mercury in the fish as well, depending on how large the fish is and where the river is located. Fish such as tuna and albacore can have high levels of mercury because they are types of the larger fish.  

  Scurvy can occur because of the lack of vitamin C. Carbohydrates are also needed for energy.  Living off fish would fufill the amount of protein needed, but the person would not have a lot of energy due to the lack of carbohydrates.

  Calcium is needed for bone strength. Calcium can found in green leafy vegetables and other dairy products.  Not in fish fish.

  It is not really possible because eventually there would be a lack of vitamins and minerals. There could also be mercury poisoning and malnutrition.

Answer 3

If Dolphins, Whales and sea lions (all mammals) can live on just  Fish. I am sure we can too.

Answer 4

Fish is high in protein and that is good for your muscle.  A body is always better with a balanced diet but people have been known to live off of just fish.
