2017 NMFS Longline Survey The 2017 NMFS longline survey sampled waters throughout the entire Gulf of Alaska (GOA) and in the Eastern Bering Sea, from June 2017 – August 2017. During the survey, catch is recorded, a subset of sablefish otoliths is collected for age reading, sablefish are lengthed, and a subset of sablefish are tagged for movement research. The results of this survey are the most influential data source used in the sablefish assessment model, which estimates spawning biomass and is used to set harvest limits.

• LL Survey Relative Population Numbers (RPNs; area weighted measures of the numbers of fish) were up from 2016 in most areas

The difference in catch (#) of fish at each slope station of the longline survey in the GOA from 2016 to 2017. Black bars indicate an increase in catch from 2016 to 2017, and red bars indicate a decrease in catch from 2016 to 2017. Red eclipse shows main area of decrease from 2016 to 2017, and black eclipse shows main area of increase.

• The number of survey stations with depredation increased from 2016 for both sperm and orca whales. These values were above the time series average.

• Total tagged fish: 3,322 sablefish, 877 shortspine thornyhead, 9 Greenland turbot, plus 3 spiny dogfish with pop-off satellite tags.

Greetings! We hope this New Year finds you in good health and thinking about the upcoming fishing season. This is the 5th installment of the Black Cod Almanac which we started to improve communication and increase dialogue between scientists and members of the industry. The intent is to provide updates on relevant research, summarized highlights of both Groundfish Plan Team and the North Pacific Fishery Management Council meetings, and news that may be of interest to those involved with the Federal sablefish fishery. Please feel free to pass on, or send us email addresses of others who may appreciate receiving these newsletters.

2017 November Groundfish Plan Team Meeting Highlights http://www.npfmc.org/fishery-management-plan-team/goa-bsai-groundfish-plan-team/ Dana Hanselman presented the sablefish assessment during the November 2017 NPFMC Groundfish Plan Team meeting that was held at the Alaska Fisheries Science Center in Seattle, WA, November 13 – 17, 2017.

The 2018 assessment included the following new data: ▪ Catch: updated catch for 2016, new projected

2017-2019 catches ▪ Relative abundance: 2016 longline fishery,

2017 longline survey, 2017 GOA trawl survey ▪ Ages: 2016 longline survey, 2016 fixed gear

fishery ▪ Lengths: 2016 fixed gear fishery, 2016 trawl

fishery, 2017 longline survey, 2017 GOA trawl survey

▪ Depredation: estimates of killer and sperm whale depredation in the fishery were updated and projected for 2017-2019

Summarized results:

▪ Abundance indices: The 2017 longline survey abundance index was up 14%. The 2017 fishery data are not available yet, but decreased 23% in 2016 (this is a time series low). The 2017 GOA trawl survey was up 79%.

Plan Team cont.

▪ Recruitment: The last two above-average year classes, 2000 and 2008, each compromise 12% and 15% of the projected 2018 spawning biomass. These will both be fully mature in 2018. The very large estimated 2014 year class is expected to compromise about 4% of the 2018 spawning biomass, despite being about 8% mature. More discussion on recruitment is highlighted further in the newsletter. The following figure shows percent contribution of each year class to total spawning biomass.

▪ Model results: spawning biomass is projected

to increase rapidly from 2018 to 2022, and then stabilize; author recommended 2018 ABC (quota) is 14,957 t (14% increase), which is much lower than the maximum due to uncertainty in the size of the 2014 year class.

▪ Apportionment: The Plan Teams

recommended following the authors’ continued approach of a fixed apportionment of ABC (+14% across all areas to reduce overall ABC variability). See text below regarding apportionment strategy work that has begun.

December 2017 NPFMC Meeting Highlights The December NPFMC meeting was held in Anchorage, AK, December 4 - 12, 2017.

2018/2019 GOA Groundfish Specifications

The Council concurred with the author’s recommended ABCs for the 2018 and 2019 groundfish fisheries which account for whale depredation. Sablefish overfishing limits (OFL), acceptable biological catches (ABC), and total allowable catches (TAC) by area for 2018 are below:

Area OFL (t) ABC/TAC (t)

Gulf of Alaska 22,703 11,505

Western 1,544

Central 5,158

W. Yakutat 1,829

SE Outside 2,974

Bering Sea 2,887 1,464

Aleutians 3,917 1,988

Fixed Gear CV Rockfish Retention The Council adopted a purpose and need statement and initiated an analysis regarding the requirement of full retention of rockfish on fixed-gear catcher vessels. Requiring full retention of rockfish could improve the identification of species when catcher vessels are subject to electronic monitoring, improve data collection by providing more accurate estimates of catch, and reduce incentives to discard rockfish, reduce waste, reduce overall enforcement burden, and promote consistent management between State of Alaska and Federal fisheries.

The Council requested that staff consider the following issues as part of the analysis:

• Whether increasing the MRAs for rockfish species would reduce the amount of catch that would need to be monitored to ensure that it does not enter commerce

• The costs and feasibility of processing, handling, and donating rockfish that are retained in excess of an MRA and which cannot enter commerce

• Potential inconsistencies between State and Federal management.

Recruitment Event We previously reported that there were several observations Gulfwide of young of the year (YOY) sablefish in 2014, and age-1 in 2015. The potential for the 2014 year class being one of the largest recruitment events is being realized, as evident in both the trawl and longline surveys.

The 2015 and 2017 trawl survey length compositions show a high proportion of fish between ages-1 and 3. The figures below show that larger age-one sablefish were appearing in the 2015 trawl survey length composition (left panel) in the 30-40 cm range, and the 2017 trawl survey length composition (right panel) shows 3 modes with potentially 2 or more year classes.

GOA trawl length compositions

The 2016 longline survey also had an extremely high proportion of age-2 fish and a relatively high proportion of age-3 fish. The figure below shows the proportion of female sablefish catch of each length (cm) on the longline survey from 2014, 2015, 2016, and 2017 in comparison with the 10-year mean. The two left side bumps in 2016 (blue line) and 2017 (pink line) are evidence of possible high recruitments in 2014 and 2015.

The 2014 year class is estimated to be 10 times higher than the long-term average. Red line represents overall average.

Sablefish Maturity Female sablefish maturity work has been completed and published results can be found in the following publications:

Rodgveller, C. J., Stark, J.W., Echave, K.B., and P.J.F. Hulson. 2016. Age at maturity, skipped spawning, and fecundity of female sablefish (Anoplopoma fimbria) during the spawning season. Fish. Bull. 114:89-102.

Rodgveller, C. J. 2017. Female sablefish age-at-maturity in Alaska applicable to stock assessment. AFSC Processed Rep. 2017-12, 23 p. Alaska Fish. Sci. Cent., NOAA, Natl. Mar. Fish. Serv., 7600 Sand Point Way NE, Seattle WA 98115.

Main findings: 1) Much of the summer is too early to definitively tell if a

fish will spawn in the coming winter. Only at the tail end of the survey, which occurs during the second half of August in the CGOA, can we assume that fish will spawn will have developing eggs.

2) The proportion of mature fish that are not spawning (skip spawning) varies by year: 21% in 2011 and 3-6% in 2015.

3) Skipped spawning is likely related to energy reserves at least 6 months prior to spawning, around the time when fish initiate ovarian development if they will spawn in the coming winter.

Sablefish Logbook Program

Fishery data (collected in logbooks and by observers) are used in the sablefish stock assessment in calculations of abundance and apportionment of catch. The majority of fishery data comes from logbooks that are collected by the International Pacific Halibut Commission (IPHC). Logbook data is weighted more heavily in calculations than observer data because of the higher sample size. We appreciate that fishermen voluntarily turn in sablefish fishery information. In 2016, 72% of the vessels that turned in logbooks were under 60 ft, collecting data voluntarily. Keep recording catch in both numbers and weight for each set, when possible. This will allow us to track seasonal and annual changes in fish size.

In the EGOA, there was an increase in average weight as the season progressed: average weight in spring was 5.9 lbs, 6.8 lbs in summer, and 7.6 lbs in fall. Although fish size increases in the fall, catch rates and effort decreases.

THANK YOU for voluntarily working with the IPHC to enable our use of this data. Vessel size, name, and owner and operator are all masked from NMFS and only data summarized by NMFS areas (e.g. CGOA) are shared with the public.

Apportionment Simulation Project

Apportionment of sablefish ABC to management areas has been fixed at the 2013 proportions for several years to address increasing variability. We have now begun examine/evaluate different apportionment alternatives through simulation modeling. Simulations will allow us to compare the performance of the current method for apportionment to several alternative. We will be seeking your feedback throughout the process, so stay tuned. In the meantime, if you have suggestions for ideas that apportionment should address, please contact Kari Fenske ([email protected]).


New Research: Early Life Movement: Tagging A small pilot program was conducted in 2017 to capture, tag, and release age-0 sablefish from the Gulf of Alaska. Fish were captured in a trawl net with a live box attached to the cod end. Once on board, fish were measured, tagged, allowed to recover in a holding tank overnight, and then released. A total of 46 age-0 sablefish were tagged and released near Kayak Island. The tagged fish ranged in size from 140-184 mm in length. The goal of the tagging was to test whether age-0 fish could be successfully captured, tagged, and released alive. All of the tagged fish survived the tagging and handling process and were released. If future funding permits, we will continue to tag and release these young fish and hope to learn more about their very early life movements. Please report these tagged fish if captured. The tags are yellow and begin with the letter code “YY” followed by a 4-digit number.

Shortspine Thornyhead Movement:

While not a sablefish, many of you may have turned in a tag from a shortspine thornyhead (idiot) over the years, and may be interested in the first published report of idiot tagging.

• Total of 13,897 tagged idiots have been released, 228 have been recovered (2016 total numbers)

• Surprisingly, idiots can travel large distances; 11% recovered >100 nm from release location

• A small number of tagged idiots crossed management and international boundaries

• 20 (9%) of the 228 recovered tagged idiots were recaptured in British Columbia, Canada

• The current geographic scale of management in Alaska for shortspine thornyhead appears to be appropriate

New Research: Early Life Growth A pilot growth study was carried out on field-caught age-0 sablefish in 2016 at the Ted Stevens Marine Research Institute (TSMRI) to generate temperature-dependent growth rates, consumption rates, energy allocation strategies, and fasting energy loss rates. Individually tagged age-0 sablefish were cultured at five temperature treatments (5°, 8°, 12°, 16°, and 20 °C). Growth data from this study showed that juvenile sablefish have a narrow “growth efficiency window” between 12°- 16 °C, with highest growth at ~16 °C (61 °F). This “growth efficiency window” closely matches the water temperature at which age-0 sablefish are captured in the GOA. Energy allocation data suggested that age-0 sablefish prioritize rapid growth over energy storage. Currently, we are conducting an ongoing larger scale age-0 sablefish growth study at TSMRI designed to elaborate on the results from the pilot study, and to generate data that can be used in building energy budget and growth models for these fish. These models can be utilized to estimate the effects of changing environmental and food conditions on growth, condition and energy allocation. [email protected]
