what does "fallowed" or "use splice" mean Easywater?

I think he means "Allowed" and "Slice" is a product used in fish farming to attempt to control sea lice.

No, he meant "fallow". Dictionary.com is your friend.

Usually the term is used in the context of land agriculture, but it equally applies to aquaculture.

Or if you use Chrome for a web-browser just get the Dictionary Extension then all you have to do is double click a word and the definition pops up.

Pinks have been having good returns for several years ever since the fish farms fallowed or used Slice during pink fry migration periods.

True enough Easywater, SLICE applications and fallowing did/does happen, to the credit of the farmers, but how about this explanation … Almo and company were just plain wrong when they predicted the extirpation of pinks in the Broughton.  Pink salmon seem to be doing just fine along the Pacific coast, if they are given what they need … good spawning gravel with suitable water temperatures and flows, a fishery that allows enough spawners, and a healthy estuary.

I know you follow this stuff Easywater but for those who may have missed it, this link previously posted on FWR may help explain the rise of the pinks.

I read that article and thought it was reaching a bit.
Sockeye EAT pink fry so more pinks should mean more Sockeye, no?

How about 2 articles by your favourite anti-farmer?

Regarding Slice:

Fallowing - see item 7.
http://www.alexandramorton.ca/lb/pdf/AM_Memorandum.pdf

Just kidding, I just put those in there for general information for others about the fallowing and Slice references I mentioned.

I feel that one item in the article may be valid in that pinks may climate change survivors.
They return to the rivers later than most Sockeye returns so they come in to cooler waters.

Is it a coincidence that this year's Sockeye return is much bigger than the other 3 years?
This year's return comes back around the same time as pinks instead a month earlier.

Or perhaps Sockeye are suffering the same fate as rainbow trout - acidic ground runoff in lakes due to de-forestation and pine beetle damage?

No coincidence at all in my mind.  Later run Fraser River salmonids will out perform earlier run fish because they encounter less warm water and high flows, but in the early 90's and until recently, these later fish entered the Fraser far earlier than normal and suffered huge mortalities ... Cultus sockeye took a huge hit, as did Weaver Creek, Harrison River and to a lesser extent, the Shuswap component, all mainly due to Parvicapsula minibicornis, a kidney parasite.   The good news is this early entry into freshwater seems to have stopped, that is late run stocks are now returning at near historic dates so hopefully this years Late run fish stay in the salt for as long as they have to, and ... we don't fish the $hit out of them while they stage and then enter the Fraser.

There are others better qualified than I to talk of sockeye nursery lakes limnology and water chemistry ... hope they do.

Lol you don't even have to fish for those. You just walk down there and grab one from the tail for the BBQ 

[dave c]

Good Luck short floating for these. One inch leader below float. LOL

[Floater]

I wonder how many of them the hatchery workers will bother to spawn.
