They taste the same and replenish stocks for recreational fisherman… what has killed there numbers is indiscriminate fishing by commercial operations…. We take fuck-all…. They take millions and believe that’s ok!!!!… I say BS!!!

The "purpose" the hatcheries have left us is genetically weak fish and smaller fish.

While I agree that the comms guys had an impact on fish numbers in the past there is not much impact now if any.

Biggest issue with Ashburton, Rangitata and Rakaia is the loss of water compared to earlier times. Also for many years young fish ended up on paddocks due to poorly designed/function fish screens on RDR irrigation scheme.

Depends where u are… No?

lack of water and crap in the water has had a big impact. can remember going out with my uncles in the late 80s fishing round skipton and mid reaches of the opihi we would see schools of salmon , was a rare day that nothing was hooked . doubt my kids will experience that now

Show me the data???…. I’ve fished the Kenai and the copper rivers…. Smaller YES… genetically weak??…

Truck loads more examples , just google "salmon hatcheries weaking genetics".

This has been an issue for years (and is well documented) in Norwegian/Salmon specifically with escapees from fish farms breeding with the native wild salmon

Yep heaps of evidence.

Increased disease, lower reproductive rate etc etc

What's the name of that movie about it??...ill try to find it.

Interesting articles indeed ,hard to despute the evidence for sure…..

what’s interesting for me is that during the salmon fishing opens in the NW,you are specifically only allowed to take specified types ie ,hatchery,coho,chinook,etc etc…. For a period of time we are allowed to take hatchery AND native salmon…… I’ve pulled 2 on the same day,,size,colour,taste texture are almost identical….. very difficult once they’ve been filleted to tell the difference……depending on the time of season(usually late)…. The only real difference is colour,the late season (native)chinook have a deeper red colour….

As someone who dedicated his life to salmonids in the PNW...which is where most of these documentaries and debates originate I'd take all these "fact based" studies and documentaries with a heap of salt as they will spin everything to their side of the story...Seaspiricy says the ocean will be void of fish in 20 years or some such foolishness. Also, I'd just point out...aren't your NZ "wild" salmon runs just strays from hatcheries/farms in the first place? Anyway...
Also I hope to see to Wairau at some point this season...I doubt these fish have seen many backtrolled kwikfish
Good luck to all this season!!

Originally were wild fish and thru 70s/80s ish supplemented by Acclimatisation Society (Now F&G) stripping eggs from wild fish and hatching them / returning smolt to rivers.

how were they origonally wild fish??? they had to come from somewhere to begin with.....
now if only the biggest fish were used as donors would it not counteract the argument of poor genetics??? I seem to recall something similar done with trout in Taupo some years back...

I would suspect from what I saw on hatchery "open days" when I was a kid, any hand male fish got mixed with any handy female fish! That was about the extent of any genetic "selection"

kind of like what happens when we shoot the best stags while still in velvet and leave the dregs to do the funky chicken with the hinds then...
yet we still see some absolute crackers turn up in any season with decent tucker after a year with less pressure.....
