NGOs File Suit against regulatory agencies to stimulate management decision-making, and force stronger conservation efforts.
Unfortunately, many with sportsfishing interests pile on top of well-meaning conservation efforts, but too often - for all the wrong reasons.
There is a real dichotomy of opinions about whether or not recreational fishermen should be treated with the same bluntness and forced into the management regimes imposed on commercial fishermen.
In many regions and for many species, sports fishing is more of a threat than are commercial fishing activities. The Gulf of Mexico and Caribbean are the most well documented examples, of this situation.

Long-term prediction of air temperature river debacle. National Hydrological Institute, 10:207 236 (in Russian).||
This science was all championed later by Dzerdzeevskaya, B.L., and V.M. Kuganskaya, and Z.M. Vitvitskaya. 1946. (Translated title) Classification of Circulation Mechanisms Over the Northern hemisphere, and Features of Synoptic Seasons. Trudy - NIU GUGMS Ser 11, Issue 21.
Four known transitions occurred since observations began in 1889: - a cool epoch: 1912-24 began a warm epoch; 1942-54 - back to Cool; 1965-77, Warming and 1997-99 - back toward Cooling after ENSO Warm Event; The antilog peaks being centered between these dates - i.e 1904-06; 1940-42; 1969-70; 1988-91 - These latter correspond with peak periods for the world's 12 major production ocean fisheries.
13 Atmospheric Categories, comprising 30 or so special classes or

ACI categories - as per the various generations starting with
Vangengeim, in the 1930-40s.
The objective of AA Girs and colleagues 1956 & 1971 reviews was to show that there were two epochs that were identified starting with the 1899 observations, and ending with 1966. Two Epochs ended - 1923, and then again in 1953, forming one complete cycle. Since 1954, up to 2002, the Arctic Institute has identified a repeat of that earlier cycle, which may have finalized in 1998 -i.e., the recent generic Global Regime Shift that everyone is now 'predicting' - and that various ocean processes and responses by various organisms and weather phenomena - told us occurred back in 1998 or so.

|2002||NE and Mid-Atlantic US Trawl Fisheries||
"Best Available Science" isn't anywhere near good enough" - as "Trawlgate" causes fishermen to lose respect for NOAA/NMFS surveys - and associated science that forms the basis for management.
"Serious errors" occurred from 2000 onward in the rigging of the bottom trawl used in the Spring and Winter Bottom Trawl Surveys. These surveys are conducted annually in the waters from North Carolina to Maine and are considered the primary - in instances the only - data sources for assessments of the condition of most of the important commercial and recreational fisheries in New England and the Mid-Atlantic.
According to NMFS, the rigging error - mismatched towing cables which would cause the net to not fish properly - occurred before the 2000 Winter Survey - and is only now being rectified.
Winter and Spring Bottom Trawl Surveys have been the "flagships" of the NMFS research effort in the Northeast. Extending back 40 or so years, they have been extolled as the "best available science" on the various fish populations sampled - they provide a long-term picture of how those populations fluctuate over time. These problems with gear in Northeast Science Center Bottom Trawl Survey raise many questions about groundfish and other stock assessments.
Maine Senator Olympia Snowe and Massachusetts Senator Ted Kennedy "have requested that the Inspector General of the U.S. Department of Commerce conduct a thorough examination of the manner in which NMFS maintains, inspects, operates, and verifies accuracy of equipment for collecting fishery data, including the timing and cost of these activities.
NMFS NE Fisheries Center News Release:
Letters from fishermen to NMFS regarding their experiences with surveys; under October 24 entry:
Recognizing problems with the various surveys conducted by NMFS, the fishing industry has initiated side-by-side projects in which commercial fishing boats take samples in the same locations under the same conditions as the NMFS survey vessels, providing "ground truth" for the surveys. In each of the northeastern fisheries where this was done (surf clams, summer flounder, monkfish, sea scallops), the commercial boats caught significantly more per station than the NMFS vessel.
Side-by-side surveys should be required for all such survey activities.

Per Capita Trends in fish catch are slowly sinking, as human population growth slows - but -
How do we keep track of all the fisheries and catch, now that many local Asian fishermen are now allowed, even encouraged to go out onto the high seas for the first time in centuries - to seek new opportunities? Then there is the rapid increase in cultured fish - often dependent upon fish meal from other, non-local resources.
Pew Foundation sponsored Ransom Myers & Boris Worm "Nature" paper is a Media Hit - But - since they have obviously never read any of the historical literature on high seas fisheries, nor have any idea of it's historical evolution, their story will be rebutted.
While some of the North Atlantic fisheries they comment upon are indeed diminished, their explanations are not adequate - see graphic at top of page. Also, most of their over-generalized conclusions about high seas tunas and billfish fisheries are simply wrong!

The best examples of such dynamic systems are those with the greatest species diversity - a direct consequence of these dynamics, leading to constant re-enforcement of species diversity at population and regional scales. Darwinian factoid.

Consideration of ocean conditions in the management of salmon - new report by Bisbal and McConnaha suggests how the consideration of ocean conditions can be incorporated into salmon management, especially as it relates to the Council's mission in the Columbia River.
Amongst the many fundamental hypotheses that are under examination, the role of planktonic shifts associated with Climate Regime Shifts and consequent Upper Trophic Level Changes are likely to be highlighted as data sets and System Science evolves.
The Northwest Power Act of 1980 (Northwest Power Planning and Conservation Act), authorized the states of Idaho, Montana, Oregon and Washington to form the Northwest Power Planning Council and called for the Council to develop the Columbia River Basin Fish and Wildlife Program (NPPC 1994). The program addresses the restoration of fish and wildlife affected by hydroelectric development in the Columbia River Basin. The recent amendment directed the Council to "consider the impact of ocean conditions on fish and wildlife populations" during implementation of its program. Consideration of ocean conditions has its most direct impact on anadromous fish populations, such as salmon and steelhead.

Menakhem Ben-Yami states the fact that: "Management
should be based, apart from statistics, on ecological study of what
makes each particular fish stock tick. Responses of all stages of the
stock (from eggs and larvae to spawners) to changing environmental
factors, hydrological (temperature, salinity, oxygen, sea currents)and
biological (food and predators), pollution, essential habitat status,
etc.), should be studied and, as far as possible, understood, to create
a scientific basis for intelligent management decisions. Not everything
can be quantified - never mind, as long as we see relative differences,
and nothing bad would happen if fishery science stops pretending that
it can tell in precise figures how many fish there are in the sea and,
consequently, how many fish can be "safely" taken out."
"Fishing, like most businesses, need to be cognizant of technical and economic efficiency. Without improvements in efficiency, operations become less profitable, and economic problems for individuals dependent upon fishing increase. "
"We are then left with the basic questions of (1) how can we maintain efficiency, (2) compete in the market, (3) have a consistent high-quality supply of seafood; (4) and maintain a domestic industry and related communities?"
"This study originated between the Governor of Virginia, the Sec. of Natural Resources, the VMRC, and the industry. There is an MOU between the various parties to conduct this study."
