Out of curiosity how much of our TAC is eaten up by release mortality on oversize fish? Or is it at all?
If it is, I assume a further reduction in size would mean an increase of TAC being eaten up by release mortality?

Its an estimate - 40,000 lbs. I rather doubt there is that level of precision applied to the calculation of the estimate. There would be more discard mortality associated with release of smaller halibut because the biomass is much smaller - very few large hali around comparatively speaking to the dominant age class that most anglers will encounter.
So if you look at the tables below from a study on length at age in years, and compare that to the 2 dominant age classes (2012 & 2016 - 13 years old and 9 years old respectively)...the average size of a 13 year old halibut will be around 90cm and an 8 year old will be around 80cm for Females. For Males a 13 year old will be around 75cm, and an 9 year old will be around 67cm.
Another way to look at is is the size of fish that we will mostly encounter will range from around 65cm to low 90cm. There will still be a few larger fish around, but those will be less common than in prior seasons because they are aging out of the population and therefore not available to catch.

Thanks for that. So when we go from 133-126 we don’t lose any tac to the release mortality aspect of the equation then. Seems like bit of a win for us in that regard

Is this a typo for area 4? The fishing was incredible up here last year but there was no one here. Guides were busy but boat launches empty all year

Yes, the data is more than a little surprising. The SFAB Halibut Working Group has challenged the data, citing on water observations as not in alignment with the data recorded. Still awaiting a detailed response.

Also area 3 has 2 lodges with maybe 8 boats total.
These numbers are 100% way off as well, I wouldn’t be suprised if they are 100,000 over in area 3 and in area 4.

could you imagine that would be amazing, that would free up a lot of tac

Yes I was surpised to see this as well. Traffic was substantially lower than past years when we were out.

I can imagine yes! Those numbers are completely fabricated. My boat was on the water over 130 days last year and we saw maybe 20% of the traffic we normally see. Anyways I’m not going to blow up a very informative post and take away from all the hard work tons of people (searun, derby and lots of others I’m sure) myself and everyone look forward to seeing how this year shapes up and we appreciate your guys hard work year after year!

do you get a opportunity to discuss the data before dfo submits it to the IPHC?
Pure curiosity.
Didn't they move a bunch of FF's and increase then amount of fish per net right around 2021.
I am assuming the hatched Hali's would go to protected waters.
The FF's have had some fish kills due to low oxygen levels caused by excrement build ups
And their sucking water up and using if to blast huge numbers of sea lice off Atlantic Salmon.
Mostly in the north on the west coast of the island where most of the commercial guys are?
"The most recent and comprehensive analysis of oxygen changes in the global oceans suggests there has been an average 2% decline since 1960".
If it is O2 depletion then it isn't likely it isn't natural or just ocean warming. All the way back to 1960 and now measured at 2% less.
A study I read shows ocean temps on average increase by .75 F degrees in 2021, less than one degree and gone back down a bit since.
IMO if global warming is blamed on man made events, then what about man made events that don't take decades to see the results.
In Australia there is an entire bay that is now sterile due to Fish Farms. Very low oxygen levels. I think they have air circulation for the nets there as well.
Just typing to pass the time but very much on cause and effect. Not everything needs 50 years and ignoring 1000's of studies to finally agree there just might be a correlation.
Have they ever decided who is responsible for the excrement and antibiotics that is washed away to other areas from the FN, FF's outside of their legal waters?

The issues and concerns were discussed- no meaningful investigation to get to the bottom of the potential data error.

Any reason why you think the traffic was so reduced? Chinook regs keeping people away? Do these numbers make sense in a "normal" year?

In the past Prince Rupert has a very bad rep for fish processing, that has come around now.
Chinook closure doesn’t help. I can’t speak as much to why but I know for sure people arnt there!
These numbers don’t make sense on a normal year no. There probably closer to accurate over 5 years. The sizes don’t work and the piece count doesn’t work. There’s no point in dwelling on it now I believe everything is submitted hopefully we have a different person making up the numbers next year!

The time is NOW for the public fishery (rec sector) to push hard to get more than 15% of the TAC!! They did in in WA state we can do the same here!
It is a no brainer that the public fishery generates more way money for the economy then the commercial sector does when it comes to the halibut fishery. This is what we need to push our politicians for.

Got a link for what Sporty's were able to do in Washington State?

I also feel that its worth mentioning that no one is more disgusted with the 25% tariff on Canadian goods than me, however I refuse to lower myself to blaming American fisherman/tourists that want to support our local economy and enjoy fishing with family and friends in Canada. Try putting the shoe on your foot and see how that feels. It makes no sense blaming fisherman from Washington State and Oregon for what comes from Washington DC. Crap if we were keeping score on what Trudeau has done over the last decade we all would have to wear a clown costume when were fishing.

Sports fishermen in the USA lobbied and were successful in having the USA recreational halibut quote allocated increased. Now the recreational quota is 30% instead of 20%. So essentially they have increased their halibut quota by 50% while the commercial fisherman took the reduction from 80% to 70% of the halibut allocation. It seems that if there was a recreational lobby effort in Canada to change our current 80/20 split to 70/30 that there is a reasonable expectation for success given the results down south.I also feel that its worth mentioning that no one is more disgusted with the 25% tariff on Canadian goods than me, however I refuse to lower myself to blaming American fisherman/tourists that want to support our local economy and enjoy fishing with family and friends in Canada.
