Canned light tuna has about .118 PPM, Albacore is .353 PPM of Mercury
If you weigh 120 lbs, one-4 ounce can puts you at about 40% of the daily recommended limit, if you weigh in at 170 lbs, you are at about half that.
It takes several months for Mercury to leave your system so it accumulates if you eat the tuna every day or so.
The limits are set by the EPA
The EPA reference dose (RfD) is defined as the amount of mercury a person, including sensitive subpopulations, can be exposed to on a daily basis over a lifetime without appreciable risk of effects.
The EPA RfD is 0.1 µg mercury per kg body weight per day. When using the mercury calculator at GotMercury.Org, this value (adjusted for a week of exposure) is the value to which your mercury levels are being compared.
This level corresponds to a blood mercury level of 5.8 ug/L or 5.8 parts per billion (ppb) mercury. Blood mercury levels below this value are considered to be without appreciable risk by the EPA.
There is a calculator for most fish at the following website:

Where does most tuna come from?
Tuna is caught in warm, temperate and deep parts of the Atlantic/Indian oceans, then processed (ie gutted etc), put into tins and sold to consumers. it is very famous in Asia (one of the seven continents)
Yes, all species of tunas have scales, however, they are tiny (almost microscopic).
Regarding whether Tuna is Kosher, however, is a little more complicated. In order for a fish to be Kosher, it must have both fins and scales (this you probably know already). However, in Jewish law, the fish must have scales that are easily removed with your fingers or a knife such that it does not cause damage to the skin (kaskeses). This would prohibit under Kashrut any fish whose only scales are microscopic in nature.
Therefore, if the tuna is a tuna where the scales are not readily visible, then they are not kaskeses, and therefore the tuna is not kosher.

AnswerYes, most varieties have scales... therefore, they are Kosher.Yes especially the ones not in tins.
Tuna is a carnivore. It feeds on different types of fish (mackerel, herring, hake…), squids and crustaceans. Unlike other fish, tuna is able to increase and maintain the body temperature few degrees above the temperature of surrounding water.
This food will only last a few days. 3 days in the refrigerator if the food is stored properly. Place in an air tight container for the best results. You can transfer the food to the freezer if longer storage is needed.
Some tuna species (such as yellowfin tuna and skipjack tuna but not albacore tuna) associate with dolphins in the ocean. This helps themto avoid being eaten by sharks, which are one of their predators. Sharks are strongly attracted to tuna fish, even if the tuna fish are not injured or bleeding. However, examination of the contents of the stomachs of various sharks indicates that tuna fish have evolved to swim too fast for sharks to catch up to them and end up being eatenby sharks only occasionally.
Other predators of tuna fish include orcas (killer whales), false killer whales, pilot whales, bottlenose whales, bottlenose dolphins, and marlins but the giant, filter-feeding whales and sharks can only eat small fish, which are usually not small tuna fish. Also, sperm whales occasionally eat tuna fish but like sharks, they tend to be too slow to catch up to tuna fish in most situations.
However, because of man's strong appetite for tuna fish, humans are the only real possible threat to the sustainability of tuna fishing.
Interestingly, blue sharks can swim as fast as tuna fish. Also, seals can swim faster than great white sharks but end up being frequently eaten by great white sharks because great white sharks wait patiently and then ambush them from deep below by surprise. All predatory sharks like to pretend that they are just harmless filter feeders when a large school of fish approaches them.
No, gluten is typically found in cereal products. Of course, there may be gluten in the dressing, or accompanying foodstuffs but nothing in the fish itself.
What location was the biggest tuna ever caught?
The world's largest yellowfin tuna, breaking the previous record by 22 pounds, will escape recognition officials say because of a technicality on who touched who's pole.The rod that reeled in the 427.9-pound fish last Thursday off the coast of Purto Vallarta, Mexico was assisted by a deckhand the crew admitted, breaking the rules set by the International Game Fish Association for an unassisted catch.Because of that technicality, the beast wrestled from the water for a half an hour by Robert Pedigo, though with the help of a local captain working as a deckhand, will go unrecognized in the books.
