Washington halibut

[Bushbear]

Reelfast - The catch rate they credited us with was 170 fish per day with an estimated average weight of about 20 lbs or an estimated catch of about 3400 lbs per day. We get to live with that for another year or two....since WDFW and the IPHC have agreed to use the highest catch/day in the previous 5 years. Using those numbers and the allowable catch for Puget Sound, (divide 57,393 by 3400 = 16.8) and we're getting 17 days of fishing in each of the 2 "areas" (MA 5 - Sekiu aka the western region and MA 6,7,8-1,8-2,9,10 aka the eastern region). We'll overlap Memorial Day weekend and have 5 days on the water that weekend. The rest of the time, we're fishing Thursday/Saturday each week and we'll live with the tides and hope for the best.

To expand a little bit, the IPHC sets the halibut quotas (poundage by area) for the US and Cananda. We're Area 2A and it covers N. California, Oregon, and Washington. The catch is divvied up amongst the states and then is divvied up by tribal, non-tribal commercial, and recreational fishers. The following quote came out of a WDFW letter: "The International Pacific Halibut Commission (IPHC) met a few weeks ago and adopted a total allowable catch (TAC) for Area 2A of 989,000 pounds for 2012, which is slightly higher than the 2011 quota of 910,000 pounds. The IPHC also approved the Pacific Fishery Management Council’s Catch Sharing Plan for 2012." From the 989,000 lbs available in 2A, OR and CA get a little over 203,000 lbs to divvy up, WA sport fishers get 214,110 and that is split with the ocean fisheries getting 157,717 lbs and Puget Sound getting 57,393. The non-tribal commercials get 224,957 lbs and the tribal fishers get 321,650 for commercial take and 24,500 lbs for subsistence and ceremonial take.

By contrast, Canada has an allocation this year of 7,038,000 lbs giving the rec fleet 1,055,700 lbs for harvest and the commercial fleet having 5,982,300 lbs available. The Fisheries Act of Canada sets the aboriginal/First Nation limits. I'm presuming that, as in the US, they come off the top of the 2B quota and maybe off the commerical share since the DFO rules would appear to read that the rec fleet gets 15% of the 2B quota.

Overall, there was a major cut in the allowable harvest poundage for halibut. There was a slight increase for 2A and I think 2C (SE Alaska) got a bump. Everyone else was cut.

If you're interested in halibut fishing, you should look at the IPHC website. There is a lot of information to be gleaned. Here are some links and data:

http://www.iphc.washington.edu/publications/regs/2012iphcregs.pdf

26. Sport Fishing for Halibut—Area 2A
(1) The total allowable catch of halibut shall be limited to:
(a) 214,110 pounds (97.1 metric tons) net weight in waters off Washington; and
(b) 203,783 pounds (92.4 metric tons) net weight in waters off California and Oregon.

27. Sport Fishing for Halibut—Area 2B
(1) In all waters off British Columbia:*
(a) the sport fishing season is from February 1 to December 31;
(b) the daily bag limit is two halibut of any size per day per person.
(2) In British Columbia, no person shall fillet, mutilate, or otherwise disfigure a halibut in any manner that prevents the determination of minimum size or the number of fish caught, possessed, or landed.
(3) The possession limit for halibut in the waters off the coast of British Columbia is three halibut.
* DFO could implement more restrictive regulations for the sport fishery, therefore anglers are advised to check the current Federal or Provincial regulations prior to fishing.

24. Aboriginal Groups Fishing for Food, Social and Ceremonial Purposes in British Columbia
(1) Fishing for halibut for food, social and ceremonial purposes by Aboriginal groups in Regulatory Area 2B shall be governed by the Fisheries Act of Canada and regulations as amended from time to time.


I do envy the length of the BC halibut season. I hope to find a fish or two this summer plus some WA Chinook that are headed South.

Yep some pretty impressive stats i must say..your posts are as varied as your aliases ..your statement about catching more fish in your day pretty much somes it up.. TROLL AWAY MOROON! Anyone have an extra can of that spray ??

Here you go ........

An interesting read on halibut management/biology

Mar 15, 2012 - 01:56 PM AKST

Biology may play biggest role in halibut battle

If halibut thrived on hard feelings, there would likely be a trophy fish for everyone by now.

With another round of deep cuts to the halibut harvest for the 2012 season that began March 17, and regulatory actions to manage trawl bycatch and the allocations between commercial and sport fishermen bogged down in controversy, there has been no shortage of finger-pointing among user groups over the last few months. (See story page 26.)
Commercial halibut fishermen have absorbed seven straight years of harvest cuts, and they now point at charter operators in Southeast for going over their allocations by more than 3.7 million pounds from 2004 to 2010.

Charter operators, in turn, point at the commercial harvest during the same period and the strategy employed by the International Pacific Halibut Commission that resulted in catch quotas subsequently estimated to be millions of pounds in excess of the target rates.

And everyone, it seems, is pointing at the Gulf of Alaska groundfish trawlers who are allowed to take up to 4.4 million pounds of halibut as bycatch every year. Bycatch is the taking of a nontarget species, such as catching halibut while fishing for cod. Halibut is a prohibited species catch for these fishermen and must be discarded rather than retained.
Besides the trawlers, plenty of blame is also being heaped on the North Pacific Fishery Management Council for its decades of inaction when it comes to reducing the amount of trawl halibut bycatch since the current limit was set in 1986.

In the end, though, while fishing pressure and bycatch undoubtedly are having an impact, the biggest problem with the halibut resource may be biological.
The average size of halibut has declined drastically over the last 10 to 20 years, and the “size-at-age” of surveyed halibut is smaller than at any point since measurements began back in the 1920s.

According to the IPHC, the average weight of a 12-year-old halibut has dropped from 25 pounds in net weight in 1993 to less than 15 pounds in 2011. The average net weight of a 20-year-old halibut has declined from more than 100 pounds in 1993 to less than 40 pounds in 2011.

Females reach maturity around age 11 and continue to grow, while males reach maturity around age 8 and the growth rate slows greatly. At the current rates, many males may never grow into the legal size of 32 inches, confounding projections of future abundance and possibly exacerbating the rebuilding efforts as spawning-age females represent a greater proportion of the harvest.

The decline in average size-at-age defies easy explanations when considering the possibility for man-caused effects. Similarly, the lack of information about ocean conditions and species complexes from the early 20th century makes it equally difficult to pinpoint common environmental effects that could be causing the reduced size of halibut.
“If this were simple, I think we would have solved it,” said IPHC Executive Director Bruce Leaman. “If it was as easy as pointing a finger, I’d be glad to do it.”

Theories abound

There was no trawl fishery in the Gulf of Alaska during the 1920s during the last period when such small average sizes of halibut were observed.

There was a heavy bottom trawl effort by foreign fleets off Alaska’s coasts during the 1960s and 1970s when halibut quotas were far smaller than even the current low levels, but the average size-at-age was more than double what it is today.

The targeting of the largest halibut in the commercial and charter sectors has also been considered based on a theory that removing the females predisposed to growing the largest and capable of laying the most eggs is contributing to the decline.

However, the IPHC notes that the largest females represent a small percentage of the total spawners, and that by the time they have reached such a size they have already contributed a decade or more worth of their genetics to future age classes.

The possibility of “fishery induced evolution” — changes in average size caused by removing only halibut of a legal length — has also been generally dismissed as a factor.
The commercial halibut fishery in Alaska is second only to salmon in terms of its history, dating back to the 1880s, and if the stock were impacted by size selectivity of fishermen it is believed such an effect would have been observed long before now.

One of the more common theories is that the decline in average size of halibut is caused by food competition among halibut and arrowtooth flounder.

After the “regime shift” in the late 1970s that significantly altered ocean conditions in the North Pacific, the total biomass of halibut and arrowtooth flounder have expanded in tandem.
Arrowtooth flounder is now the largest fishery resource in the Gulf of Alaska, but it is also one of the cheapest. There was enough arrowtooth flounder in the Gulf to set a harvest of as much as 213,000 metric tons in 2011, yet the harvest quota was set at 43,000 metric tons and about 30,000 metric tons were actually taken.

Besides the low value of the arrowtooth flounder, targeting the fish results in high halibut bycatch rates of 25 percent or more that typically close the fishery before the total arrowtooth flounder quota can be taken.

A two part posting. Original article exceeded the character limit for postings on this website

Human environment

Some trawl representatives have suggested that constraining their fleet because of the current halibut bycatch caps may be contributing to the issue of food competition by leaving so much arrowtooth flounder in the water.

A similar argument is made with respect to the large percentage of juvenile halibut that makes up the majority of trawl bycatch. The argument goes that an abundance of small halibut is causing the reduced average size, and that leaving more in the water will lead to more food competition and many of the fish saved will never reach the legal size anyway.

That sort of thinking rings hollow for the commercial halibut fishermen, whose catch of juveniles on longlines at least have a shot at growing into a legal size after being released alive while those killed after being mashed up in trawl nets have none.

According to IPHC analysis, trawl halibut bycatch is made up of about 75 percent juveniles by number of fish. But by weight, more than 60 percent of the trawl bycatch is made up of fish larger than the legal size of 32 inches.

The high relative abundance of juvenile halibut in the coastwide estimates often referred to by the trawl fleet is not concentrated in the Gulf of Alaska, either, but is in the Bering Sea.
The total biomass of halibut and the overall number of fish is flat or declining in the central Gulf of Alaska — considered the nexus of the Pacific halibut stock — where the derby-style race for groundfish continues and observer coverage is 30 percent or less.

In the Bering Sea — where the head-and-gut trawl catcher-processors (known as the Amendment 80 fleet) were organized into cooperatives in 2008 and now have 100 percent observer coverage — the number of juvenile halibut is up while bycatch has declined over the past four seasons.

Halibut migrate across the North Pacific from northwest to southeast, and the IPHC has provided information to the council stating that each pound of halibut saved in bycatch will increase yield by more than 1.1 pounds. Further, because females grow larger than males, each pound of bycatch saved is estimated to yield an additional 2.2 pounds to the spawning biomass.

The IPHC has learned through tagging studies that halibut migrate between areas much more than previously thought, leading its biologists to conclude that bycatch saved has downstream benefits as well.

So as the North Pacific council debates whether the contemplated cuts in bycatch of 5 percent to 15 percent will benefit the halibut resource enough to justify the hardship on the trawl fleet, the more appropriate question may be whether the cuts go far enough.

The council also must consider whether to assign fishing privileges to the Gulf groundfish trawl fleet to achieve the same kind of bycatch savings that have been seen in the Bering Sea and in the Gulf rockfish program, and whether that becomes a greater priority than cutting bycatch across the board first.

It is up to the IPHC to set appropriate harvest levels to conserve the current stock of legal-sized halibut, but it is up to the North Pacific council to protect the halibut of all sizes taken as bycatch by trawlers and longliners.

Managers at the North Pacific council must address all sources of fishing mortality they can control in order to meet their legal obligations to minimize bycatch while achieving optimum yield.

When it comes to the mandate to minimize bycatch, fishermen facing possible constraints often note the caveat that follows — “to the extent practicable.”

However, there is also a caveat to achieving optimum yield. The Magnuson-Stevens Act states that optimum yield may be reduced by any combination of economic, social or ecological factors.

In other words, minimizing bycatch isn’t as simple as setting a cap, and optimum yield isn’t defined only as achieving the full harvest of a species quota.

Optimism remains

There is no easy answer for what is causing the reduced size of halibut, and the simplest solution may be time. The decline in average size didn’t occur overnight, and if it is part of a normal, cyclical downturn, the trend won’t reverse itself any faster.

Gregg Williams, senior biologist with the IPHC, started with the commission in 1977. The quota for the central Gulf of Alaska that year was a mere 9 million pounds.
In 2012, the central Gulf quota is 11.92 million pounds, a 50 percent cut since 2007 but still 3 million more pounds than when Williams started at IPHC.

“The fishery rebounded from that fairly well since then,” Williams said. “There’s a few folks out there that think the sky is falling, but I have a hard time believing that based on my time involved in the fishery.

“I’m fully confident that this resource will bounce back.”

Very informative information Bushbear!
Thanks for the posting.
As far as one of the earlier posts directed at me pointing a spray can and saying Anyone have an extra can of that spray.."TROLL AWAY MOROON! (I think he has one too many o's in MORON?"
This is the attitude of some heavy duty fishermen (Sometimes Fishing Guides)...can't stand any comments contrary to their attitude of Cash in NOW....fish til you drop or fish until there are no fish left AND always blame someone or something else!

Washington Hali season

As I read these posts, and everyone is getting fired up, I wondered if anyone else saw the natives long lining (in area seven U.S.) yesterday. Bummer, why do they always get the first season, shouldn't we alternate between recreation and tribes each year to make it fare?

 

[Bushbear]

If you want change in who gets on the water first in WA, you're going to have to get the Feds andt the state to change the rules. The state position appears to be that too many fish would be caught in April (maybe because that is when they are in our waters) and we'd go over quota too fast based on the state formula. The tribes can start March 17 and fish until their quota is taken or November 7 whichever comes first.

22. Fishing by United States Treaty Indian Tribes
(1) Halibut fishing in Subarea 2A-1 by members of United States treaty Indian tribes located in the State of Washington shall be regulated under regulations promulgated by NMFS and published in the Federal Register.
(2) Subarea 2A-1 includes all waters off the coast of Washington that are north of 46°53´18´´ N. latitude and east of 125°44´00´´ W. longitude, and all inland marine waters of Washington.
(3) Section 13 (size limits), section 14 (careful release of halibut), section 16 (logs), section 17 (receipt and possession of halibut) and section 19 (fishing gear), except paragraphs (7) and (8) of section 19, apply to commercial fishing for halibut in Subarea 2A-1 by the treaty Indian tribes.
(4) Regulations in paragraph (3) of this section that apply to State fish tickets apply to Tribal tickets that are authorized by Washington Department of Fish and Wildlife.
(5) Section 4 (Licensing Vessels for Area 2A) does not apply to commercial fishing for halibut in Subarea 2A-1 by treaty Indian tribes.
(6) Commercial fishing for halibut in Subarea 2A-1 is permitted with hook and line gear from March 17 through November 7, or until 321,650 pounds (145.9 metric tons) net weight is taken, whichever occurs first.
(7) Ceremonial and subsistence fishing for halibut in Subarea 2A-1 is permitted with hook and line gear from January 1 through December 31, and is estimated to take 24,500 pounds (11.1 metric tons) net weight.

Yep, saw the longlines there as well...........Sucks knowing they have the green light to wipeout some areas way before our recreational season arrives. Sadly there is nothing we can do about it as the tribes in WA. have major infuence in every saltwater recreational fishery opening.

I remember just a few years back when our straits hali season opened in early April and that was always the best fishing as the hali are usually on thier outward migration by then. The month of May was always way less productive and that is why the WDFW gives us May to fish instead of April. If they opened it in April we would only get 6 days cause they know we would probably catch more fish, and we know what would happen if we go over our TAC, the following year our season would be cut in half.
