"The eastern Bering Sea bottom trawl survey has been conducted annually since 1975 by the Resource Assessment and Conservation Engineering Division of the Alaska Fisheries Science Center, National Marine Fisheries Service. The purpose of this survey is to collect data on the distribution and abundance of crab, groundfish, and other benthic resources in the eastern Bering Sea. These data are used to estimate population abundances for the management of commercially important species in the region. This document includes the time series of results from 1975 to the present. In 2017, 395 total stations (375 standard stations and 20 resampled stations in Bristol Bay) were sampled on the eastern Bering Sea shelf from 4 June to 15 August. In early June, colder bottom temperatures extended into Bristol Bay creating the need to resample 20 stations due to delaying effects of cold water temperature on red king crab reproductive cycle. There was an overall decrease in biomass and abundance in male red king and blue king crab and female red king crab. There was an overall increase in immature female blue king crab and a decrease in mature female biomass and abundance, with no mature female blue king crab being caught in the St. Matthew Island Section. There were overall increases in immature and legal male and immature and mature female biomass and abundance in Chionoecetes bairdi and C. opilio crab, and a decrease in mature male biomass and abundance in Chionoecetes bairdi and C. opilio crab. In addition to the standard eastern Bering Sea survey, in 2017, following the conclusion of the standard survey, 145 stations were sampled in the northern Bering Sea region, encompassing the region south of Bering Strait and including Norton Sound. These stations were sampled between 1 August and 2 September. We report the results of this survey separately from the eastern Bering Sea survey, within the northern Bering Sea section of this report. Blue king crabs occurred largely in the region north of St. Lawrence Isand, in greater densities than were observed for the St. Matthew and Pribilof stocks. Red king crab occurred primarily in Norton Sound, at densities roughly intermediate between those generally observed in the Bristol Bay and Pribilof Districts. Chionoecetes opilio dominated the catch, with the highest densities observed during the 2017 Bering Sea survey occurring to the south of St. Lawrence. Immature male and female opilio were predominate, although mature females were observed, primarily along the western edge of the survey grid, and in the north, near Bering Strait. Morphometrically mature (“large-clawed”) male C. opilio were scattered throughout the survey region, but most prevalent within catch near Bering Strait."--Publisher's website.

Changes in regulation enacted in 2013 have enabled the Alaska Fisheries Science Center's Fishery Monitoring and Analysis Division (FMA) and the Alaska Regional Office's Sustainable Fisheries Division to work collaboratively on an Annual Deployment Plan (ADP). Each ADP documents how the National Marine Fisheries Service (NMFS) plans to deploy observers into fishing activities for the coming year under the limits of available funding. Draft ADPs are presented to the North Pacific Fishery Management Council (Council) during September - October and are finalized in December. The sampling design for observer deployment has two elements: how the population is subdivided (i.e., stratification schemes) and how available samples are allocated (i.e., allocation strategies). Here the relative performance of 10 alternative sampling designs (at the primary sampling unit- the trip) are compared in support of the draft 2018 ADP. These alternative sampling designs consisted of the combination of two stratification schemes (gear-type only or gear-type × tendering activity), two metrics upon which to base optimizations [one consisting of discard of groundfish with Prohibited Species Catch (PSC) of Pacific halibut and the other consisting of the prior and PSC of Chinook salmon], and three allocation strategies (no optimization, a "hurdle" approach to optimization, and a optimization only). All optimization allocations incorporate three variables measured over the past 3 years: variance in the metric, the average cost of observing a trip, and the number of trips. Total afforded sample size is determined by the available budget and the average cost of observing each trip. Resulting selection rates derive from sample size, allocation weightings and the anticipated fishing effort which was defined as the most recent complete year of data. The total number of observer days that can be afforded is 4,062 which represents a 33% increase from 2017. Gap analyses that examine the chance of at least one or three observed trips in a NMFS Area × gear type combination (cell) were used as a performance metric. Gap analyses illustrated that stratifications based on gear type (3 strata) were outperformed by stratifications based on gear type × tendering activity (6 strata). Potential gaps in observer coverage appear to be mostly concentrated in areas with low fishing effort with fewer than 12 trips in a cell. Simulations were performed to measure the potential impact of unknown vessel participation in electronic monitoring (EM). The variability in gap analyses from randomized differences in EM participant vessels was relatively minor (less than 10% probability of observation shifts across deployment designs). The NMFS recommended an observer deployment design for the draft 2018 ADP that has gear type × tendering stratification and uses a "hurdle" approach to sample allocation wherein 15% base coverage is obtained first across all strata and the remainder is optimized according to the variance in the metric of discarded groundfish catch combined with PSC Pacific halibut and Chinook salmon. At their October 2017 meeting the Council did not support the NMFS recommendation and instead proposed a five strata design with optimal sample allocations based on discarded groundfish catch and PSC of Pacific halibut only. Comparisons between the NMFS and Council recommended designs were included in the final 2018 ADP. [doi:10.7289/V5/TM-AFSC-364 (https://doi.org/10.7289/V5/TM-AFSC-364)]

"This NOAA Technical Memorandum represents a 2017 update to the Commonwealth of the Northern Mariana Islands as a Fishing Community published by Allen and Amesbury in 2012. This fishing community profile update aspires to provide a comprehensive view of the Commonwealth of the Northern Mariana Islands (CNMI) as a fishing community. The report begins by presenting recent social, economic, and tourism information gathered by the Government Accountability Office (GAO) and the Marianas Visitors Authority in the CNMI. These data are followed by data on four key topics that emerged from interviews conducted by the author in 2016 with the CNMI fishing community. Next, findings from low income fish consumption in 2015 are presented, aggregated at the island level. These data provide the only current estimates of fish consumption on Tinian and Rota. The report concludes by presenting some additional empirical information that supplements the primary data gathered in the profile"--Executive Summary.

"The HPSCI Majority's move to release to the House of Representatives its allegations against the Federal Bureau of Investigation (FBI) and the Department of Justice (DOJ) is a transparent effort to undermine those agencies, the Special Counsel, and Congress' investigations. It also risks public exposure of sensitive sources and methods for no legitimate purpose. FBI and DOJ officials did not "abuse" the Foreign Intelligence Surveillance Act (FISA) process, omit material information, or subvert this vital tool to spy on the Trump campaign."--Opening paragraphs.

The "Nunez Memo" Chairman Nunes issued the following statement: "The Committee has discovered serious violations of the public trust, and the American people have a right to know when officials in crucial institutions are abusing their authority for political purposes. Our intelligence and law enforcement agencies exist to defend the American people, not to be exploited to target one group on behalf of another. It is my hope that the Committee's actions will shine a light on this alarming series of events so we can make reforms that allow the American people to have full faith and confidence in their governing institutions."

A genetic analysis of the prohibited species catch (PSC) of chum salmon (Oncorhynchus keta) collected during 2016 from the federally managed walleye pollock (Gadus chalcogrammus) trawl fishery in the Bering Sea and from the federal groundfish fisheries in the Gulf of Alaska (GOA) was undertaken to determine the overall stock composition of the sample sets. Samples were genotyped for 11 microsatellite markers from which stock contributions were estimated using the current chum salmon microsatellite baseline. In 2016, one genetic sample was collected for every 30.6 chum salmon caught in the Bering Sea midwater trawl fishery. The evaluation of sampling in the Bering Sea based on time, location, and vessel indicated that the genetic samples were representative of the total chum salmon PSC in the Bering Sea. The majority of the 114 chum salmon samples from the A-season were from Northeast Asia (37%) and Eastern GOA/Pacific Northwest (PNW) (37%) stocks. Based on the analysis of 2,701 chum salmon collected throughout the B-season, the largest stock groups in the catch were Eastern GOA/PNW (35%) and Northeast Asia (31%), followed by Western Alaska (19%), Southeast Asia (9%), Upper/Middle Yukon (5%), and Southwest Alaska (< 2%) stocks. The chum salmon caught in the Bering Sea in 2016 shared general patterns of stock distribution with those from past years, but differed by some finer-scale spatiotemporal strata. Of the 473 chum salmon samples from the GOA groundfish fisheries, the highest proportion was from Eastern GOA/PNW (93%) stocks, similar to previous years.

"A genetic analysis of samples from the Chinook salmon (Oncorhynchus tshawytscha) bycatch of the 2016 Bering Sea-Aleutian Island (BSAI) trawl fishery for walleye pollock (Gadus chalcogrammus) was undertaken to determine the overall stock composition of the bycatch. Samples were genotyped for 43 single nucleotide polymorphism (SNP) DNA markers and results were estimated using the Alaska Department of Fish and Game (ADF&G) SNP baseline. In 2016, genetic samples from the Bering Sea were collected using a systematic random sampling protocol where one out of every 10 Chinook salmon encountered was sampled. Based on the analysis of 1,910 Chinook salmon bycatch samples collected throughout the 2016 BSAI walleye pollock trawl fishery, Coastal Western Alaska and British Columbia regions (34% and 29% respectively) dominated the sample set with smaller contributions from West Coast US (14%), and North Alaska Peninsula (13%) regions. Analysis of temporal groupings within the pollock "A" and "B" seasons revealed changes in stock composition during the course of the year with lower contributions of Coastal Western Alaska and North Alaska Peninsula regions and higher contributions of West Coast US, British Columbia, and NW Gulf of Alaska, regions during the "B" season when compared to the "A" season"--PDF Abstract.

"Defining essential habitats for fishes and invertebrates is an important step in managing groundfish species in Alaska waters. Species distribution models have been widely used to describe the potential habitat of species found in marine and terrestrial systems. The models themselves can take a number of forms, from relatively simple frameworks such as generalized linear or additive models to complex modeling frameworks such as Maximum Entropy Modeling (MaxEnt). We used several modeling methods and data from scientific surveys and commercial fisheries to define essential habitats for 36 species from the Gulf of Alaska. Adult, juvenile, larval and egg stages were seasonally modeled where data were available. Bottom depth was the dominant variable determining the distribution of most adult and juvenile life history stages. Sea surface temperature was the most important predictor of ichthyoplankton distribution. The model results were used to develop maps that depicted the boundaries delineating essential fish habitat for each species and life stage. These maps will be used for marine spatial planning and assessing impacts of anthropogenic activities in Alaska’s marine environment."--Publisher's website.

"Aerial surveys are flown December 01 through March 31 each year in the Southeast United States to detect North Atlantic right whales in their primary calving area. The purpose of the aerial surveys is to contribute to (in prioritized order): • Population monitoring via detection and identification of individual right whales including cow/calf pairs occurring in the Southeast United States. • Monitoring trends in human-related serious injuries and mortality. • Vessel-strike reduction. Given these objectives, we focused aerial surveys in areas where we expected the highest number of right whale detections. Additionally, the National Oceanic and Atmospheric and Administration's National Marine Fisheries Service (NOAA Fisheries), U.S. Navy, U.S. Coast Guard, and U.S. Army Corps of Engineers have agreed to implement the "Early Warning System" (EWS) -a system of aerial surveys and communications designed to provide mariners with information on whale locations. The goal of the EWS is vessel-whale collision mitigation. This report briefly summarizes results from the NOAA Fisheries-administered aerial surveys and the EWS during the 2015/2016 North Atlantic right whale calving season"--PDF Introduction.
