No, they do not.
Look it up. They have not had it for years. They still do not have all the oceans done yet.
I don't doubt it for a minute, it's hard to make evidence based policy decisions without evidence.

I am not a scientist, and he said "Food, predators and especially ocean warming COULD be factors." i'm just saying FISH FARMS "COULD" be factors also.He is a scientist and he said:
no one really knows why ocean survival has been so poor. Food, predators, and especially ocean warming could be factors. “It’s smart to be humble and admit we don’t know,” he said. “All we know is they didn’t come back.”
Seems to me that lots of data have been collected. I am referring to the annual LineP cruises. https://www.waterproperties.ca/linep/2011-27/index.php#ProfilesI find this pretty disturbing, with all the various government and NGO entities studying marine life, climate change, etc. are we really saying we don't have water temp data available? We know the technology has existed for decades. This is an incredibly basic parameter and we don't have measurements, something is wrong where is the money being spent? Where is all the data we're basing our science and policy decisions on? This doesn't add up.
Lapointe said most ocean temperature readings are taken at the surface and may not fully reflect temperatures experienced by salmon deeper in the water. “We don’t really have the systematic sampling out there … don’t have the data to really answer the question you might want answered.”
A so-called “blob” of warm water identified in the North Pacific in the winter of 2013 and lasting into 2015 resulted in ocean temperatures in some areas of three degrees C above normal.
Fisheries and Oceans Canada said that warm ocean conditions can cause a change in species of plankton, from high-nutrition northern types to low-nutrition southern types, while increasing the presence of warmer water predators.
