Tuna do lay eggs (oviparous).
Not all fish lay eggs, those that don't, like some sharks, usually retain the eggs and they hatch inside the mother. This is called ovoviviparous.
Some sharks are viviparous, giving birth to live pups that did not hatch from an egg inside the mother. These sharks are able to obtain food from the mother and also by eating their weaker siblings.
By Fertilization.......
next: lays egg
or
hatch egg

tuna is very good scientists say that it increases brain power very fast and it contains omega 3 and a funny word called phuritombus which is in the juice which is good for the brain and relieves stress Important Addendum:
The smaller the species, the better; large tuna have high concentrations of Mercury, which is extremely toxic. If you're buying canned tuna, "chunk light" has less mercury than "solid white".
NAY
Almost all fish are cold blooded, however some species of tuna e.g. Pacific Bluefin, have warm blooded features, enabling them to raise their body temperature above that of the surrounding water.
Tuna eat smaller fish, but they live in salt water, not fresh. Edit: That's not quite 100% true. While the tuna that we all get in the store is saltwater, there's a lake in Nicaragua that has freshwater tuna living there.
Tuna and other ocean life is "renewable" IF humans:
- don't pollute the oceans with garbage and non-biodegradable junk (e.g. metals, plastics)
- don't over-fish
- don't pollute the atmosphere so badly that it affects earth's sources of water so drastically that it changes the pH levels to more acidic; increases evaporation making the water more salty; decreases oxygen for ocean plants and fish
- don't add chemicals to earth's waters-- from land-river chemical runoff; from ships leaking oil or other chemicals; from acid rain overloading water sources
