>>>despite the fact that inflation is running at the lowest level in decades. Here is someone who does not do his own food shopping. Food prices have exploded since 2008, when the house of cards first collapsed. I used to be able to buy 5 cans of store-brand chunk tuna for $3.00. Now the store brand is gone, replaced by a national brand, and it's $1.29 per can (up from $1.00 per can at the start of this year). And that's just the most egregious example from my own experience. Food packaging has also shrunk dramatically, another way prices actually rise while the "store price" remains almost the same. |

Fish have an ecosystem. They have to be fished at the about same rate they are breeding. If they are not, they are considered overfished. If they are overfished enough they go extinct. In the meantime the supply goes down and less fish are caught. This causes prices to rise. Tuna, like most fish, are overfished.

According to information collected by the International Seafood Sustainability Foundation (ISSF), the Eastern Pacific stock of yellowfin is overfished and some overfishing is occurring in the Indian Ocean.The northern and southern Atlantic Ocean stocks of albacore are also overfished.The skipjack tuna, while quite resilient, could easily slip into a vulnerable state due to overfishing if improperly managed.
Bigeye tuna are prized in Asia for sashimi as well as frozen and fresh in other markets. As bluefin tuna populations shrink around the world, pressure on bigeye fisheries is increasing. According to information collected by the ISSF Scientific Advisory Committee, overfishing is occurring in Eastern and Western Pacific Oceans. Bluefin tuna populations have declined severely from overfishing and illegal fishing over the past few decades –not just Atlantic bluefin tuna, but also Pacific bluefin tuna and Southern bluefin tuna. Population declines have been largely driven by the demand for this fish in high end sushi markets.
Albacore is what comes in the cans, the amount that is allowed to be taken out of the ocean was lowered in 2011 to try to combat overfishing.

Albacore stocks in the Atlantic are assessed by ICCAT - the International Commission for the Conservation of Atlantic Tunas. The latest stock assessment of South Atlantic albacore was conducted in 2011 and including catch, effort and size data up until 2009. ..... The 2008-2011 TAC for the South Atlantic albacore stock had been set at 29,900 tonnes. In 2011, following scientific advice, the TAC was lowered to 24,000 tonnes.
Oh by the way, we are rapidly approaching "peak fish."

Faced with the collapse of large-fish populations, commercial fleets are going deeper in the ocean and father down the food chain for viable catches. This so-called "fishing down" is triggering a chain reaction that is upsetting the ancient and delicate balance of the sea's biologic system.
A study of catch data published in 2006 in the journal Science grimly predicted that if fishing rates continue apace, all the world's fisheries will have collapsed by the year 2048.
In 2003, a scientific report estimated that industrial fishing had reduced the number of large ocean fish to just 10 percent of their pre-industrial population.
