Abstract Ninety-one albacore tuna (Thunnus alalunga) captured during the 2003 commercial fishing season were tested for total mercury content in muscle tissue. The fish were harvested between 32.72°N (off Southern California) and 48.30°N (off the northern tip of Washington) between July and November. Fish weighed from 3.14 to 11.62 kg and were 50.8-86.4 cm long. Total mercury content in the albacore muscle tissue ranged from 0.027 ppm (μg/g) to 0.26 ppm. The average total mercury content was 0… 
Bioaccumulation of Mercury in Muscle Tissue of Yellowfin Tuna, Thunnus albacares, of the Eastern Pacific Ocean
TLDR
There was a positive association between Hg content and tuna size in the equatorial zone (EQZ), and the site of origin was a determinant factor in Hg accumulation, suggesting that males and females have similar feeding habits.
Determination of Hg in Farmed and Wild Atlantic Bluefin Tuna (Thunnus thynnus L.) Muscle
TLDR
Results demonstrate that for Hg, there is a better risk/benefit ratio in farmed T. thynnus, making it safer than wild tuna.
Possibility for decreasing of mercury content in bluefin tuna Thunnus orientalis by fish culture
TLDR
It was concluded that selecting diet fish species might decrease mercury contents in cultured bluefin tuna because the effect of mercury accumulation would be weakened by body growth.
Effect of Seasonality, Location, and Size on Lipid Content in North Pacific Troll-Caught Albacore Tuna (Thunnus alalunga)
TLDR
Lipid content varied considerably among tuna caught at similar latitudes; however, most fish caught below 40°N had a lipid content of less than 10%, while the fish with the highest lipid content were all harvested above 40° N.
Trial for quality control in mercury contents by using tail muscle of full-cycle cultured bluefin tuna (Thunnus orientalis).
TLDR
The quantity of mercury in full-cycle cultured bluefin tuna that were shipped for 1 year showed no increase irrespective of increases of body weight, and the overall mercury concentration could be estimated to be almost the same and/or lower than that of the tail muscle.
ASSOCIATION OF TOTAL MERCURY AND CADMIUM CONTENT WITH CAPTURE LOCATION AND FISH SIZE OF SWORDFISH (Xiphias gladius); INDIAN OCEAN
Mercury (Hg) and cadmium (Cd) are non-essential trace elements that transfer through the trophic chain which ultimately bio-accumulate and biomagnify in the upper trophic level .  The total Hg (THg)

Total and methylmercury residues in tuna-fish from the Mediterranean sea
TLDR
The estimated weekly intake was far above the established Provisional Tolerable Weekly Intake for both species, and mercury was present almost completely in the methylated form in albacore and bluefin-tuna.

Quantification and Distribution of Lipid, Moisture, and Fatty Acids of West Coast Albacore Tuna (Thunnus alalunga)
TLDR
Intrinsic quality characteristics, including lipid, moisture, and fatty acid content, of West Coast albacore tuna (Thunnus alalunga) was investigated and an inverse correlation was found for lipid and moisture content.
Chemical form and distribution of mercury and selenium in canned tuna
TLDR
The content, chemical form and distribution of mercury and selenium were determined for several samples of canned tuna, and there was no apparent correlation between the total levels of both elements.

Migration of albacore, Thunnus alalunga, in the North Pacific Ocean in relation to large oceanic phenomena
On the basis of Japanese long-line fishery data during 1970–1988, anticlockwise migration routes of albacore in the North Pacific are newly proposed. The annual migration route for mature albacore is
Blood organic mercury and dietary mercury intake: National Health and Nutrition Examination Survey, 1999 and 2000.
TLDR
Based on the distribution of BHg concentrations among the adult female participants in 1999-2000 NHANES and the number of U.S. births in 2000, > 300,000 newborns each year in the United States may have been exposed in utero to methyl mercury concentrations higher than those considered to be without increased risk of adverse neurodevelopmental effects associated with methyl mercury exposure.
