- Abstract
Three pelagic stocks in the Baltic Sea, Central Baltic Herring (CBH; her.27.25-2932), Sprat (spr.27.22-32) and Gulf of Riga Herring (GOR, her 27.28) were examined during this benchmark. Work was prepared well in advance and 3 preparatory online meetings took place between the Data Evaluation Workshop and the actual benchmark to follow up progress. The benchmark meeting advanced really well until reference points were discussed. There were follow up online meetings on 3rd and 13th March to further discuss, and agree, on reference points for the three stocks. All three stocks that was benchmarked were previously assessed with XSA, and hence a main point with the benchmark was to change the assessment model. Two of the stocks changed to SAM (GOR and sprat) whereas the CBH changed to stock synthesis (SS3). For the GOR and sprat the reference points were estimated following the ICES procedure using EQSIM. For the CBH the reference points were obtained using a Management strategy evaluations (MSE), a method previously used for one of the Northern shrimps stocks in ICES (pra.27.3a4a). There was an extensive issue list for the CBH and although not all of the issues were addressed, significant progress was made. Additional survey indices, maturity at age, weight in catch, adding age reading error, landings corrected for misreporting (Danish landings only) were all investigated and updated time series were included in the new assessment. SS3 was chosen as main assessment method and there was extensive model development work carried out in advance and presented at the meeting. An ensemble model was developed to incorporate uncertainty in natural mortality. Three scenarios of natural mortalities were developed from rescaling the natural mortalities from a multispecies model for the Baltic (SMS) with life history parameters. An objective weighing approach was used based on model performance statistics diagnostics to develop the final assessment.

Fisheries and aquaculture ,Baltic Sea (ICES Ecoregion) ,The sea and human culture and societies - Abstract
The duration of ice-coverage is one of the key environmental factors directly affecting the northeastern Baltic fisheries. The 1990s can be characterized as years of relatively warm winters and reduced ice-coverage. As a result, the open sea trawl fishery became possible year round, except in the most eastern part of the Gulf of Finland and close to the coast. The increased possibilities for the winter trawl fishery encouraged Estonian fishermen to employ bigger open sea trawlers. At the same time, substantial declines in demersal fish stocks occurred, in part due to environmental processes. This included reduced inflow of saline water from the North Sea that resulted in reduced salinity and oxygen levels in the northeastern Baltic and contributed to the collapse of bottom trawling for cod and flounder. These resulted in significant changes in the exploitation pattern on the main fish stocks of herring, sprat, cod. and flounder with important socio-economical implications for Estonia.

Fisheries and aquaculture ,Baltic Sea (ICES Ecoregion) - Abstract
The mean weight-at-age of herring and sprat has shown a decreasing trend, following a decrease in the marine component of the zooplankton during an extended period of absence of large inflows to the Baltic Sea. Simultaneously, the open-sea herring stocks have decreased in abundance, while some gulf stocks of herring and sprat stock have increased. The changes observed have had an effect not only on relationships within the ecosystem, but also on the assessment and exploitation of fish stocks in the Baltic Sea.Article from Marine Science Symposia Vol. 219 - "Hydrobiological variability in the ICES Area, 1990-1999", symposium held in Edinburgh, 8-10 August 2001.

The main objective of the Working Group on Biological Parameters (WGBIOP) is to review the status, issues, developments, and quality assurance of biological parameters for use in assess-ments and management that are in line with the requirements of end-users. In this final year of the three-year term, WGBIOP operated under challenging circumstances due to COVID-19 measures. The initial action plan was replaced by a more flexible one, where online plenary and subgroup meetings were spread over the year with intersessional work to finalize the proposed deliverables. WGBIOP continued the review of past exchanges and workshops under the remit of the working group. Since 2019, these calibrations on age, maturity, and larvae identification have been carried out in SmartDots, an online platform for sharing images and facilitating the reading of otoliths, staging of gonads, and identification of early life stages. Developments are underway to include an improved calculation of modal age and error matrices in the SmartDots standard report. WGBIOP investigated ways to incorporate error matrices into assessments and studied the effect of this inclusion together with stock assessors. Requests for new exchanges and workshops were reviewed, with a focus on stocks to be bench-marked in the coming years. Issue lists were scrutinized, problems identified, and information provided to stock coordinators via regular channels and through the Stock Identification Data-base (SID). Despite close cooperation with stock assessors and continued efforts, it has not been possible to further streamline the WGBIOP workflow with the benchmark process. This will be addressed with the Advisory Committee. The need for validation studies was stressed by the repeated low levels of agreement between readers of some stocks and recurring issues and recommendations to WGBIOP. Lack of resources is the main obstacle. As a first step for measures to prioritize validation studies, WGBIOP iden-tified precision, trueness, and feasibility of validation methods (as well as the urgency for the assessment). WGBIOP continued investigations into new life-history parameters for integrated assessment and advice in cooperation with end-users (Working Group on Integrative, Physical-biological and Ecosystem Modelling-WGIPEM and Regional Coordination Groups-RCGs). This included a standardization and quality assurance action plan for stomach sampling. Efforts have also been taken to streamline data and workflows across databases and groups. A step has been taken in the standardization of quality assurance procedures at the regional level. Institute-level overviews of methods and quality assurance protocols used for ageing and maturity are now available. Also, a new method for quality grading was developed, tested, and implemented in SmartDots.

- Abstract
The Scientific, Technical and Economic Committee for Fisheries (STECF) not hold its 63rd Plenary Meeting as originally foreseen on 16-20 March 2020 but was requested to draft its advice by written procedure instead.-- 94 pages, The STECF was originally planned to meet in plenary on 16-20 March at the JRC, Ispra. Due to the emergent covid-19 situation in northern Italy and later on the whole of Europe, the meeting was first shifted to Brussels, and then cancelled and replaced by a written procedure with STECF members addressing the ToRs from their home offices. The original ToRs were re-prioritised by the Commission in order to facilitate the STECF working under non-ideal conditions. In addition, the Commission supported the STECF chair and vice-chair, rapporteurs and those STECF members being able to contribute to the written procedure by issuing individual ad hoc contracts. Below DG MARE lists the points to be developed under written procedure. All other points originally included in the draft ToR and Agenda are either postponed to one of the future plenaries or to be dealt with under different procedures, or will no longer be dealt with by STECF. After consultation within DG MARE, this exceptional written procedure to replace the Plenary March session, will need to deal with the following points and ToR. These concern, in summary: - 2 points in the Atlantic – both technical measures - 3 points in the Med – some diversity in the subject - 1 point in the Black Sea – on data collection. Finalization of the written procedure on all topics was foreseen for 3 April 2020

- Abstract
The main objective of the Working Group on Biological Parameters (WGBIOP) is to review the status, issues, developments, and quality assurance of biological parameters for use in assess-ments and management that are in line with the requirements of end-users. In this final year of the three-year term, WGBIOP operated under challenging circumstances due to COVID-19 measures. The initial action plan was replaced by a more flexible one, where online plenary and subgroup meetings were spread over the year with intersessional work to finalize the proposed deliverables. WGBIOP continued the review of past exchanges and workshops under the remit of the working group. Since 2019, these calibrations on age, maturity, and larvae identification have been carried out in SmartDots, an online platform for sharing images and facilitating the reading of otoliths, staging of gonads, and identification of early life stages. Developments are underway to include an improved calculation of modal age and error matrices in the SmartDots standard report. WGBIOP investigated ways to incorporate error matrices into assessments and studied the effect of this inclusion together with stock assessors. Requests for new exchanges and workshops were reviewed, with a focus on stocks to be bench-marked in the coming years. Issue lists were scrutinized, problems identified, and information provided to stock coordinators via regular channels and through the Stock Identification Data-base (SID). Despite close cooperation with stock assessors and continued efforts, it has not been possible to further streamline the WGBIOP workflow with the benchmark process. This will be addressed with the Advisory Committee. The need for validation studies was stressed by the repeated low levels of agreement between readers of some stocks and recurring issues and recommendations to WGBIOP. Lack of resources is the main obstacle. As a first step for measures to prioritize validation studies, WGBIOP iden-tified precision

SDG 14 - Life Below Water - Abstract
The main objective of WGBFAS was to assess the status and produce a draft advice of the following stocks: • Sole in Division 3.a, SDs 20–24 • Cod in Kattegat, Cod in SDs 22–24, Cod in SDs 24–32 • Herring in SDs 25–27, 28.2, 29 and 32 • Herring in SD 28.1 (Gulf of Riga) • Herring in SDs 30-31 (Gulf of Bothnia) • Sprat in SDs 22–32 • Plaice in SDs 21–23, Plaice in SDs 24–32 • Flounder in SDs 22–23 (no catch advice) • Flounder in SDs 24–25 (no catch advice) The WG was not requested to assess the following stocks in 2019, as no advice was needed: • Flounder in SDs 26+28 • Flounder in SDs 27+29–32 • Brill in SDs 22–32 • Dab in SDs 22–32 • Turbot in SDs 22–32 It was, however, decided by the group to compile and update the input data for 2018 and thereby also conduct update assessments for these latest five stocks. In the introductory chapter of this report the WG, in agreement with the ToRs, considers and comments on the ecosystem and fisheries overviews, reviews the progress on benchmark processes, identifies the data needed for next year’s data call with some suggestions for improvements in the data call, and summarizes general and stock-specific research needs. The introduction further summarizes the work of other WGs relevant to the WGBFAS, and the assessment methods used. Finally, the introduction presents a brief overview of each stock and quite extensively discusses the ecosystem considerations of the Baltic Sea and ecosystem changes that have been analytically considered in the stock assessments. The results of the analytical stock assessment or survey trends for the species listed above are presented for all the stocks with the same species in the same sections. The analytical models used for the stock assessments were XSA, SAM and SS3. For most flatfish (data limited stocks), CPUE trends from bottom-trawl surveys were used in the assessment (except plaice in SDs 24–25 for which relative SSB from SAM was used). For cod in SDs 24–32, a full analytical assessment (using SS3) could be performed, after the compilation/benchmark work undertaken in 2018–2019. The report ends with references, annexes with the response to a special request, links to Stock Annexes, and list of Working Documents.

- Abstract
The ICES Working Group on Biological Parameters (WGBIOP) general aim is to review the status of current issues and developments associated with biological parameters, supporting the Data Collection Framework and end user (stock assessment) requirements. WGBIOP continued the work of reviewing past exchanges and workshops for age and maturity organised under the remits of WGBIOP and in line with their above-mentioned aim. The focus was on the stocks to be benchmarked in the coming years and available issue lists used to identify any problems to be addressed. Steps for implementing the output from exchanges and work-shops into the stock assessment models in the form of age error matrices (AEM’s), which are now a standard output in the SmartDots reports, were outlined. SmartDots is an age reading platform that facilitates age readings based on otolith images. The most effective way to investigate this process would be during the benchmark process. The continued efforts to streamline the work-flow of WGBIOP with the benchmark process has not developed any further since the group met in 2018 and will be addressed with the Advisory Committee (ACOM) and the Planning Group on Data Needs for Assessment and Advice (PGDATA) in 2020. Continued investigations into possible new life history parameters for modern assessment included the development of a de-liverable stomach sampling and contents analysis action plan. The need for age validation studies was again highly stressed by the repeated low levels of poor agreement between age readers of some stocks with lack of resources identified as the main ob-stacle. During the scientific session on ‘Age and Maturity Validation Studies’ several experi-ment/studies were presented and discussed, mostly in light of their applicability and in 2020 a list of prioritised stocks to be validated will be finalised. WGBIOP also developed a workplan for the ICES Handbook on maturity staging of marine species. With respect to standardis

- Abstract
This was the first interim year for the multi-annual Terms of References (ToRs) for the Working Group on Biological Parameters (WGBIOP). The group met 1–5 October in Ghent, Belgium. The overall aim for WGBIOP is to review the status of current issues, achievements and developments of biological parameters and identify future needs in line with ICES requirements and the wider European environmental monitoring and management.ToR a is a generic ToR which reviews both the need for new calibration exercises on biological parameters as well as outcomes and recommendations of these. All the tables containing detailed information about national experts’ contacts, stocks handled and techniques used in age reading, were updated and greatly improved. The WGBIOP Data Quality Assurance Repository (http://ices.dk/commu-nity/Pages/PGCCDBS-docrepository.aspx) is an open source webpage containing all this kind of information and related reports traced back in time.ToR b is also a generic ToR for WGBIOP which standardises and updates guidelines for age reading, maturity staging and other biological parameter exchanges and/or workshops following the learned experienced from past inter-calibration exercises. Also, validation is essential to ensure the accuracy of biological data used as input for assessment and in the following two years WGBIOP will continue to work on identifying and prioritising these needs.ToR c links WGBIOP with the assessment groups and ensures issues and quality indicators of biological parameter are incorporated into the assessment and management of stocks. The issue lists for upcoming benchmark assessments are annually evaluated and, where necessary, action is undertaken by WGBIOP. This year also focussed on scrutinizing results from previous age and maturity calibration exercises to detect gaps in the quality assurance of biological parameters in stocks for which a benchmark is planned. This lead to additional exchanges being proposed for 2019 and 2020. Stock coordinators of upcoming benchmarks have been contacted with responses to issues on biological parameters.ToR d documents sources of life-history parameter estimates which are critical and relevant to improvement of assessment. At the same time this facilitates closer links between data providers and data end-users. As such there is a close relationship between WGBIOP and WKLIFE scientists. This year focussed specifically on fish stomach sampling and fish condition parameters.The focus of ToR e is on dealing with technical and statistical recommendations addressed to WGBIOP. In some cases this lead to the proposal of age and maturity exchanges and workshops for 2019. Also, an overview was prepared with the biological parameter information required for stock assessments. This information is fundamental for ToR c and the link to the stock assessment EG’s.ToR f further developed a prioritised list of issues for SmartDots and formulated WGSMART, the SmartDots governance group. SmartDots was implemented by ICES and the first exercises have been carried out in 2018.Besides the above ToRs, WGBIOP also organised a scientific session ‘Otoliths beyond age reading’, developed a workplan for the CRR Handbook on maturity staging and continued cooperation with RCG’s.

The objective of WGBFAS was to assess the status of the following stocks: Sole in Division 3.a, SDs 20–24; Cod in Kattegat, Cod in SDs 22–24, Cod in SDs 25–32; Herring in SDs 25–27, 28.2, 29 and 32, Herring in SD 28.1 (Gulf of Riga), Herring in SDs 30-31 (Gulf of Bothnia); Sprat in SDs 22–32; Plaice in SDs 21–23, Plaice in SDs 24–25; Flounder in SDs 22–23, in SDs 24–25, in SDs 26+28 and SDs 27+29–32; Brill in SDs 22–32, Dab in SDs 22–32 and Turbot in SDs 22–32. WGBFAS also identified the data needed for next year’s data call with some suggestions for improvements in the data call, and stock-specific research needs.The report contains an introduction with the summary of other WGs relevant for the WGBFAS, the methods used, and ecosystem considerations. The results of the analytical stock assessment or survey trends for the species listed above are then presented with all the stocks with the same species in the same sections. The report ends with references, recommendations, links to Stock Annexes and list of Working Documents.The principle analytical models used for the stock assessments were XSA and SAM. For most flatfishes and cod in SDs 25–32 (data limited stocks), CPUE trends from bottomtrawl surveys were used in the assessment (except plaice in SDs 24–25 for which relative SSB from SAM was used). For the data limited stocks, reference points based on length-based indicators were estimated (except cod in SDs 25-32 for which relative reference points were estimated using the SPiCT model). For cod in SDs 25–32, intersessional work was planned to hopefully allow returning to an analytical stock assessment in the near future. Ecosystem changes have been analytically considered in the following stock assessments: Herring in SD 25–27, 28.2, 29 and 32, and Sprat in SD 22–32

- Abstract
The eastern Baltic (EB) cod (Gadus morhua) stock was depleted and overexploited for decades until the mid-2000s, when fishing mortality rapidly declined and biomass started to increase, as shown by stock assessments. These positive developments were partly assigned to effective management measures, and the EB cod was considered one of the most successful stock recoveries in recent times. In contrast to this optimistic view, the analytical stock assessment failed in 2014, leaving the present stock status unclear. Deteriorated quality of some basic input data for stock assessment in combination with changes in environmental and ecological conditions has led to an unusual situation for cod in the Baltic Sea, which poses new challenges for stock assessment and management advice. A number of adverse developments such as low nutritional condition and disappearance of larger individuals indicate that the stock is in distress. In this study, we (i) summarize the knowledge of recent changes in cod biology and ecosystem conditions, (ii) describe the subsequent challenges for stock assessment, and (iii) highlight the key questions where answers are urgently needed to understand the present stock status and provide scientifically solid support for cod management in the Baltic Sea.
