"Salmon surge helps Norway shatter seafood record"

There are still a couple types of Norwegian farmed salmon on the Monterey Bay Aquarium Seafood Watch - Avoid - list but the industry has made great strides in the last ten years on the different areas of concern, diseases spread by overcrowding, impact on other species used as fishmeal food for the salmon, escapes and interbreeding with wild salmon, pesticide residue, antibiotics etc, etc.
Additionally one Norwegian brand grown onshore rather than in marine net pens garners MBSAW's highest rating:

"Atlantic salmon farmed worldwide in indoor recirculating tanks and the Nordic Blu brand produced by the Salten Aqua Group in Norway is a 'Best Choice.'" 

While another is a very highly rated "Good Alternate":

Norway - Nordland, Northeast Atlantic Ocean (Blue Circle Foods® brand)

For what it's worth I was speaking to a Russian lady on Friday who said she would only feed her cat Norwegian salmon, the one the cat preferred was smoked in Germany.
I asked if she would adopt me.

On to Norway's success. From The Fish Site, July 4:

A surge in the sales of both farmed Atlantic salmon and rainbow trout helped Norway record its best ever six month period for seafood exports.

Despite a 13 percent decrease in volumes, in the six months up to the end of June, Norwegian seafood exports were worth NOK 51.2 billion – up 7 percent in value compared to the same period in 2018.

“In value terms, this is a new record for Norwegian seafood exports in a six month period. Norwegian salmon accounts for about two-thirds of the growth in value this half-year,” said Tom-Jørgen Gangsø, director of market insight and market access with the Norwegian Seafood Council (NSC).

Salmon exports in the first half of the year reached 506,000 tonnes, worth NOK 34.6 billion – an increase of 5 percent in volume and 6 percent in value compared with the first half of 2018. Poland, France and Denmark were the largest recipients of salmon from Norway in the first half of 2019.

“We have seen stronger production outputs of salmon in the first half of the year than was expected at the beginning of the year. At the same time, we have experienced a growth in demand, especially from the EU and Asia....

Up the coast from the Monterey Bay Aquarium is the Monterey Fish Market which we visited in a 2016 post on mislabeled fish:

All I Asked Was "Is the Red Snapper Good Here?"

....Since the report came out (discussed here at Forbes, Dec. 2012) we've been paying attention to efforts to track fishy provenance, granted that this is more out of taste considerations than ecology, but paying attention nonetheless..

Additionally, there are other concerns.
One of the fish sometimes oftentimes, especially in sushi, mislabeled as tuna is escolar.
Be wary.
Seriously, be wary*

*From the Monterey Fish Market:

Gemplylotoxin

Members of the Gempoylidae, or snake mackerel family, contain indigestible waxy esters in their fatty tissues similar to those found in Olestra, and these esters have powerful laxative properties that affect people to varying degrees. 

Escolar and oilfish caught in the South Pacific and Gulf of Mexico are two such fish, and are quite delicious, popular menu items. Freezing and cooking won't inactivate gempylotoxins, so eating no more than 3-5 ounce servings or avoiding it is the only solution. 

Symptoms of this illness are illusive, sudden, and without warning. You can be affected at any time or in the most inappropriate place, and the results can be quite embarrassing, not to mention unhygienic.

Among the six 'Key findings' in the Executive Summary of the Oceana report:

•  94 percent of the “white tuna” was not tuna at all, but escolar, a snake mackerel that has a toxin  with purgative effects for people who eat more than  a small amount of the fish.
