'Filet-O-Fish season'?
Lent, a period of 40 days (not counting Sundays), is a religious observance in the Christian liturgical calendar that begins on Wednesday March 6th of this year. The word lent comes from the Proto-Germanic word for spring (�����Բ�����ī�Բ���) which itself is a combination of the words langaz (long)&�Բ�����;+‎&�Բ�����;tīnaz (day). So what does this have to do with Pollock you ask? In 1962, Lou Groen, a McDonald's franchise owner in Cincinnati, Ohio noticed he was losing business on Fridays as a result of many Catholics abstaining from eating meat on Fridays during this period. In response, the Filet-O-Fish was born.

Now McDonalds slings 25% of their wild-caught ����ֱ�� Pollock fish sandwiches during Lent! On social media people have referred to the season as ‘Filet-O-Fish season’ in response to many fast food restaurants offering fish sandwiches as an alternative. Here is a slightly dated article from QSR magazine which outlines various fast food restaurants and their lent menu additions: https://www.qsrmagazine.com/news/fast-food-preps-seafood-boom-during-lent

Wild-caught ����ֱ�� Pollock is available year round. There are a plethora of recipes online to construct your own Filet-O-Fish sandwich. If you want, every season could be Filet-O-Fish season!

Pollock behavior changing as climate warms?
A recent article by at reports on a trend both pollock skippers and scientists are observing. The distribution of ����ֱ�� pollock during the summer season is changing drastically which has forced commercial fishers to explore areas they have not fished previously. Last summer temperatures in the Bering Sea were nearly 9 degrees higher than normal. The article has a great overview of the Pollock fishery and how the warming climate may be responsible for the changes being observed.

Sexyback for ����ֱ�� Pollock?
A recent article on does a fantastic job describing the current market outlook for ����ֱ�� Pollock. At the Global Seafood Market Conference in 2017 Michael Holley, the commodity procurement manager for seafoods with US Foods, appealed to the industry to make pollock sexy. In an epic clapback, Trident’s Torunn Halhjem at the 2019 GSMC declared, “sexy is definitely back for wild ����ֱ�� pollock”. The undercurrent article goes in depth into the drivers that are making the current markets and demand so strong.

Trade war between US and China causes increase Russian pollock price
In a , Tom Seaman describes the effect that a 25% tariff on ����ֱ�� pollock imported to China will mean on Russian pollock prices. Typically at the end of the year, with decreasing supply, headed and gutted pollock prices rise, but the price increase they are observing appears to be caused by Chinese buyers reluctant to purchase from US sources amid the possibility of a ~25% tariff.

Potential effects of marine predation on Chinook salmon populations
Populations of Chinook salmon (Oncorhynchus tshawytscha) have displayed a decrease in size-at-return resulting from declines in age- and size-at-maturity. These changes have precipitated the loss of the oldest age classes in some populations and have occurred throughout the range of this species, suggesting a perturbation in the common marine environment. A hypothesis for the cause of these changes is increased marine mortality after the first ocean winter, potentially from predators selecting for relatively large sub-adult Chinook. Here I consider the question: could predation on relatively old individuals by salmon sharks change the age structure of a Chinook salmon population? To address this question, I first estimated total per capita prey consumption by salmon sharks using three methods: 1) daily ration requirement, 2) bioenergetic mass balance, 3) and a von Bertalanffy growth model. Second, I examined the effects of additional predation on an indicator Chinook salmon population using simulated predation scenarios and a stage-structured population dynamics model. Due to the uncertainties in salmon shark diet and total population abundance, instead of scaling individual consumption to the population level and inputting that estimate into the model, scenarios were designed and run iteratively until a shift in age structure was observed. The daily ration yielded salmon shark estimates of 1461 and 2202 kg∙yr-1, the mass-balance produced estimates of 1870 kg∙yr-1, 2070  kg∙yr-1, 1610 kg∙yr-1, and 1762 kg∙yr-1, depending on assumed diet, and the growth model output estimates of 16,900 kg∙yr-1 or 20,800 kg∙yr-1, depending on assumed assimilation efficiency. Of the estimates, those from the mass-balance may be the most realistic because they incorporated salmon-shark life history data and do not produce extreme values. Taken as a whole, these estimates suggest salmon sharks have similar energetic requirements to piscivourous marine mammals and corroborates conclusions of prior work that endothermic fishes are similar to marine mammals in metabolic rate. The predation scenarios that most closely mimicked observed shifts in age structure of the indicator Chinook salmon population focused intense and selective predation on the ocean-3 stage. This simulated predation is corroborated by emerging results from an electronic tagging study in which tagged Chinook salmon experienced high predation rates, and research demonstrating that killer whales (Orcinus orca) prefer ocean-3 fish. In summary, salmon sharks likely have high energetic requirements which could result in a large biomass of prey consumed, Chinook salmon populations are sensitive to predation at the ocean-3 stage, and salmon sharks and other predators appear to frequently consume fish at that ocean stage. Taken together, these lines of evidence point to a potentially important mechanism of top down pressure on Chinook salmon populations may explain observed changes in age-at-return, which in turn can affect population productivity.

Trident Seafoods is developing the wild ����ֱ�� pollock market in Japan with new processing plant
A  released today reports on Trident Seafoods' plan to open a value-added processing plant in Tome Japan. The main goal of the plan is to differentiate single-frozen ����ֱ�� fillets from double-frozen Russian fillets processed largely in China. The Undercurrent article features excepts from an interview with Koichi Suzuki, who runs Trident’s Japanese business, and Honomi Sugihira, one of the new plant’s project members and manages overseas public relations. 

Wild-caught in the icy waters of ����ֱ��, ����ֱ�� Pollock is one of the most abundant and sustainable seafood species in the world. A cousin to cod and similar in flavor, texture, and appearance, ����ֱ�� Pollock's lean, snowy-white meat, delicate texture, and mild flavor make it an extremely versatile and healthy seafood choice.

MSC recertification for Russia Sea of Okhotsk Pollock fishery
The Russian Sea of Okhostsk Pollock fishery is a midwater trawl fishery composed of 30 fishing companies which land ~ 840,000 metric tonnes pollock annually. It has been certified by the (MSC) since September 2013. MSC recertification occurs every five years. 

What is the MSC you ask? The MSC is an international non-profit organization whose mission is 'to use our ecolabel and fishery certification program to contribute to the health of the world’s oceans by recognizing and rewarding sustainable fishing practices, influencing the choices people make when buying seafood and working with our partners to transform the seafood market to a sustainable basis.'

In addition to the perceived environmental benefits of certification, there have been some studies demonstrating the economic . These benefit, however, may . Currently both the Bering Sea & Aleutian Islands and the Gulf of ����ֱ�� Pollock fisheries are MSC certified while the Russia Bering Sea and Navarinsky pollock fisheries were withdrawn. 

Over the next five years there were three recommendations by the MSC panel: '(1) relating to incidental seabird mortality arising from bird interactions with fishery operations at sea, (2) relating to the perceived need for an occasional but regular review of the non-stock assessment part of the management system for the stock, to be independent and provided in English, and (3) to further enhance the independent observation database especially but not only relating to observation of endangered, threatened or protected species and other non-target species'.

The entire recertification assessment can be found on the .

Pollock ranging further north?
The of the southern Bering Sea has completed and preliminary results suggest lower abundances of pollock and cod than anticipated. The Cordova times recently released an  with an interview of Lyle Britt, a research fisheries biologist with NOAA’s ����ֱ�� Fisheries Science Center in Seattle. Data collected suggest a warming trend and showed pollock collected much further north than expected. Researchers believe that this may be due to the lack of a cold pool that normally functions as a barrier to dispersal. Formal results have yet to be released, but if you are interested in ����ֱ�� Research Surveys a wealth of information can be found on .

Congratulations to Elizabeth Figus on a successful defense of her Ph.D.!
On Friday 17 November 2017 Elizabeth Figus defended her Ph.D. dissertation:

"Eyes on the Sea: Demonstrating the usefulness of local knowledge to inform commercial fisheries management in Poland and ����ֱ��" Science and decision making in commercial fisheries management take place in the context of uncertainty. This research demonstrates ways that local knowledge held by fishermen can be used to mitigate that uncertainty. This dissertation documents how fishermen in Poland and ����ֱ�� perceive management strategies in their fisheries, and compares those perceptions with traditional measures of management performance. Specific case study examples were developed through exploratory interviews with stakeholders in two study regions. Interviews were conducted with Baltic cod (Gadus morhua) fishermen in Poland (n = 31) and Pacific halibut (Hippoglossus stenolepis) fishermen in ����ֱ�� (n = 78). Qualitative and quantitative methods were used to analyze stakeholder knowledge about ecosystems, as well as their preferences about regulations. Findings show how the inclusion of stakeholder input in fisheries management need not be limited to ad hoc data collection methods in order to be meaningfully interpretable by managers.

Karl Bratvold, Aleutian Spray Fisheries joins the PCCRC advisory board!
The PCCRC would like to welcome Karl Bratvold of Aleutian Spray Fisheries to the advisory board. Karl will bring to the board decades of experience fishing in ����ֱ��'s marine waters. He first began fishing for salmon and tuna in high school during the summers. In the early 1980's he participated in the ����ֱ�� crab fishery and later transitioned to trawlers. He has worked in nearly every capacity on a fishing boat: cook, deckhand, engineer, mate and captain. He has worked for Aleutian Spray Fisheries since 1981 and served as the captain of their catcher processor Starbound for 22 years. He currently serves as senior executive and part owner of the company. Recently he led a $40 million rebuilding of the CP Starbound to decrease fish waste and achieve fuller utilization of the Pollock harvest. His dedication to preserving the sustainability of ����ֱ�� marine resources is evident in his long history with Aleutian Spray Fisheries and we are excited to benefit from his 'on the water' perspective.
