mikeccolella Posted March 4, 2019 Report Share Posted March 4, 2019 https://www.bmj.com/content/363/bmj.k4067 first see above where actual measurements were made, although you still have an association this certainly eliminates self reporting bias. ConsumerLab recently tested canned tuna and salmon and surprisingly many were not approved because of arsenic, cadmium or mercury. consumerlab top picks were for tuna: Trader Joe’s chunk light skip jack 2 oz contained 140 mg omega 3 genova yellow fin tuna for salmon top picks were Kirkland pink salmon 6 oz trader joes sockeye salman Demings red sockeye wild Alaska Quote Link to comment Share on other sites More sharing options...
Saul Posted March 5, 2019 Report Share Posted March 5, 2019 Hi Mike! The supermarket where I buy my fish, before selling filets from a given lot, tests it for Hg, heavy metals and other contamination. For example, they don't sell Ahi Tuna -- this is because these monster fish are at the top of the food chain and therefore high in mercury. Heavy metal and bacterial contamination are endemic in foodstuffs -- including vegetables. Careful testing of fish make it safer than lettuce. Skip jack tuna, yellow fin tuna amd all varieties of salmon are not large fish. So no wonder consumer labs didn't find contamination. No rocket science there. 😉 -- Saul Quote Link to comment Share on other sites More sharing options...

Saul, Why is it you speak so authoritatively on subjects about which you appear to know so little? From https://en.m.wikipedia.org/wiki/Yellowfin_tuna: Quote The yellowfin tuna is among the larger tuna species, reaching weights over 180 kg (400 lb)" Rhetorical question...

Saul Posted March 6, 2019 Report Share Posted March 6, 2019 You got me, Dean! 😉 But they're smaller when they're younger -- and therefore not at the top of the food chain. A related example: Mahi Mahi The fishmonger at my supermarket explained that Wegman's is careful to test Mahi Mahi -- they're good when they're little; but they rise to near the top of the food chain when they mature -- not good. -- Saul Quote Link to comment Share on other sites More sharing options...

And from the wikipedia article: Quote The removal of huge numbers of juvenile yellowfin and bigeye tuna that have yet to reach breeding age has major potential consequences for tuna stocks worldwide.

mccoy Posted March 6, 2019 Report Share Posted March 6, 2019 Like the vegans say, fish is probably going to be doomed. At least, wild fish. Quote Link to comment Share on other sites More sharing options...

Yes. This is true. Smaller tuna species, and all salmon species, and mackarle (spelling?) sardines and herring are among unthreatened fatty fish. (Arguably, some wild salmon species -- e.g. Atlantic salmon -- are threatened, by the escape of farmed salmon to the sea, then breading with the wild type, changing their genetics). -- Saul Quote Link to comment Share on other sites More sharing options...

Sibiriak Posted August 30, 2019 Report Share Posted August 30, 2019 Salmon farming in the Beagle Channel enters troubled waters https://www.theguardian.com/environment/2019/aug/30/salmon-farming-in-the-beagle-channel-enters-troubled-waters Quote A growing wave of resistance to the expansion of salmon farms along the Chilean coast has led to an important victory in the fight to protect a pristine fjord in southern Patagonia, home to indigenous groups and an array of stunning wildlife. Dolphins, whales and colonies of penguins thrive in the 240km-long Beagle Channel, an area of outstanding natural beauty between Chile and Argentina which attracts tourists from all over the world. Business interests, from both home and abroad, have faced fierce opposition from scientists and campaigners, who claim the introduction of the non-native species will replicate damage caused by the aquaculture industry elsewhere in the region. Quote [...] Nova Austral, which prides itself on rearing salmon without the use of antibiotics, denied any illegal activity and said it did not acquire the fishing concessions from another company until February. Quote Oceans campaigner for Greenpeace Mauricio Ceballos said part of the problem was a system that allowed smaller companies to buy concessions and later sell them to bigger investors with the financial means to implement the farms. He said: “The Chilean state has made the huge mistake of delivering aquaculture concessions indiscriminately … without any control and generating huge damage to the environment and local communities.” The withdrawal of operations by Nova Austral in the Beagle Channel is a further blow to the company after it was involved in a data-rigging scandal in June. The company’s CEO, Nicos Nicolaides, was forced to step aside after it was alleged that Nova Austral had misrepresented its fish mortality figures to regulators. The scandal has led to calls for stricter regulation of the industry. The practice of rearing Atlantic salmon has been established in Chile for three decades and more than 1,000 farms currently operate throughout the country, producing 25% of the world’s supply. Quote [...] authorities in some provinces are pushing back on the expansion of the industry due to the pollution it causes. Salmon farmed in Chile are pumped with 500–700 times the amount of antibiotics compared with salmon produced in Norway by the same companies, claims Greenpeace, while huge amounts of waste in the form of faeces and uneaten food pellets end up on the seabed. In addition there are additional pressures on marine life posed by outbreaks of sea lice and farmed fish escaping into the wild. Quote Link to comment Share on other sites More sharing options...
