Low-level radiation has been found in populations of bluefin tuna off the coast of California, a new study has found, noting that the fish are carrying radioactive material from Japanese waters more than 6,000 miles away. Researchers have found “modestly elevated levels” of two radioactive isotopes in bluefin tuna caught off the coast of San Diego in August 2011. They said the tuna picked up the radiation by swimming and feeding in the waters off the coast of Japan where the...

Migration And Habitat Secrets Of Atlantic Bluefin Tuna Studied Through Tracking
2012-05-23 05:02:09

New fish-tagging studies of young bluefin tuna in Atlantic waters off New England by researchers at the University of Massachusetts Amherst are offering the first fishery-independent, year-round data on dispersal patterns and habitat use for the popular game fish. The availability of miniaturized pop-up satellite tags suitable for smaller (two- to five-year-old) fish helped make the research possible. Fisheries oceanographer Molly Lutcavage and lead author Benjamin Galuardi say the work...

Overfishing in the Mediterranean Sea is felt in North American waters A new model built around biological data from electronic tags, ear bone microchemistry and fisheries catch data for Atlantic bluefin tuna indicates fishing on one side of the Atlantic influences the other side. Bluefin populations on both sides of the Atlantic Ocean have declined precipitously since 1950, according to the study published today in the peer-reviewed online journal PLoS ONE. The model estimates the number...

It will eat the tiny larvae of king shrimp and mantis shrimp, true shrimp, and...
