Data preparation to inform assessment and management approaches in data-limited fisheries by Amoroso, R.,Lomonico, S.,Snouffer, B.,Gutierrez, N. L. Pdf

In fisheries science and management, it is not uncommon that fishery data are used at “face value”, as inputs into data-limited assessments or empirical indicator-based frameworks for management, without first conducting a thorough exploration and critical review of the data. [Author] This practice may lead to biases in results and misdirected fishery management actions. [Author] To address intermediate steps between data collection and any analysis used to inform stock status, this manual provides guidance on how to prepare, explore and critically review fishery data in data-limited situations. [Author] Throughout the manual, guidance and sample data are provided primarily in Microsoft Excel or in comma separated value (CSV) file formats, as well as through FishualizeR, a publicly available, web-based, R Shiny app that was developed to support the manual. [Author] Instructions in this manual are not intended to present a single, prescriptive path, but rather to provide guidance that may be further tailored to each individual context. [Author] It is the authors’ hope and intent that the guidance contained in this manual will allow users to better understand their data, make corrections, and gain a deeper understanding of the data’s utility in assessment and management of data-limited fisheries.

Report of the Fisheries and Biological Data Preparation Workshop on the Shrimp and Groundfish Fisheries of the North Brazil Shelf Large Marine Ecosystem, Bridgetown, Barbados, 23-25 October 2018 by Food and Agriculture Organization of the United Nations Pdf

The Fisheries and Biological Data Preparation Workshop for the Shrimp and Groundfish Fisheries of the North Brazil Shelf Large Marine Ecosystem (NBSLME) was held in Bridgetown, Barbados 23-25 October, 2018. The meeting brought together 14 participants including fisheries officers, government organizations and FAO. The main objective of the workshop was to provide training on data preparation for stock assessment purposes and fisheries status/trends monitoring, enhance capacities in fisheries data and statistics collection at the national and sub-regional levels, and review status of data collection for the shrimp and groundfish fisheries of the NBSLME. The current state of the Fisheries and Resource Monitoring System (FIRMS) stocks and fisheries inventories for the NBSLME was reviewed and updated with inputs from participants. Ongoing work on the Data Repository and Decision Support System (DSS) for the Caribbean and North Brazil Shelf Large Marine Ecosystems (CLME+) Project and its application in the NBSLME was presented and discussed. A template for recording fisheries and biological data of key species in the NBSLME for stock assessment purposes was reviewed by participants. Furthermore, for each country and fishery, participants reviewed availability of data including, inter alia, time series of landings and fishing effort, length frequencies and socio-economic information. Additionally, a review was made of the biological parameters (e.g. length-weight relationship, growth, maturity) available for key shrimp and groundfish species in the NBSLME and data gaps identified. Information on genetic studies on shrimp and groundfish species in the NBSLME region served as background for discussion on the stock structure

Size-based assessment of data-limited inland fish stocks – Review and applications by Shephard, S., Valbo-Jorgensen, J., Abadía, J., Baigún, C., Doria, C.R.C., Fabré, N.N., Isaac, V.J., Ngor, P.B., Ruffino, M.L., Funge-Smith, S.J.,Food and Agriculture Organization of the United Nations Pdf

Assessment of data-limited fish stocks is a rapidly evolving topic in marine fisheries, and is supported by an increasing focus on the socio-economic and ecological importance of small-scale fisheries. The challenges in such systems can be compounded in inland fisheries, which are often complex, spatially dispersed and difficult to monitor. This publication reviews the application of empirical indicators and simple size-based models usually used in marine fisheries, but also applicable in inland systems. It presents case study applications for important fisheries in the Amazon River (Brazil), Tonlé Sap River (Cambodia), Paraná River (Argentina) and Lago Bayano (Panama). These studies consider issues including spatial separation of life-history stages, strong modality in population size structure, and fishing gear selectivity. Local scientific experts interpreted trends in stock state. Empirical indicators showed strong decline in size structure and relative abundance for one of the four assessed Tonlé Sap stocks. The length-based spawning potential ratio model suggested that two of the three assessed Amazon Goliath catfish stocks, and the sábalo stock in the Paraná River, were below sustainable spawning potential ratio reference points. The Lago Bayano tilapia stock appeared healthy. The review concludes that data-limited assessment methods developed for marine stocks may provide guidance for the sustainable management of important target species in inland fisheries. The methods tested are probably less applicable in non-selective fisheries where small species are preferred, or in river fisheries with extreme dependence on flood pulses. Important considerations are species life history and spatial distribution, environmental variability, and fishery sampling strategy.

General Fisheries Commission for the Mediterranean. Report of the twenty-second session of the Scientific Advisory Committee on Fisheries, online, 22–25 June 2021 by Food and Agriculture Organization of the United Nations Pdf

The Scientific Advisory Committee on Fisheries (SAC) of the General Fisheries Commission for the Mediterranean (GFCM) held its twenty-second session online, from 22 to 25 June 2021. The session was attended by delegates from 19 Mediterranean contracting parties, 11 observers, as well as representatives of the Food and Agriculture Organization of the United Nations (FAO) Fisheries Division, the GFCM Secretariat and invited experts. The Committee reviewed the work carried out during the 2019–2021 intersession, including within the framework of the mid-term strategy (2017–2020) towards the sustainability of Mediterranean and Black Sea fisheries and in light of the COVID-19 pandemic, and provided advice on status of priority stocks and ecosystems and on potential management measures addressing key fisheries and vulnerable species in the Mediterranean. In line with the subregional approach, the Committee formulated advice focusing on: i) small pelagic and priority demersal fisheries in the Adriatic Sea; ii) common dolphinfish and blackspot seabream fisheries in the western Mediterranean; iii) small pelagic and bottom trawl fisheries exploiting demersal stocks, particularly European hake, in the central Mediterranean; iv) deep-water red shrimp fisheries in the eastern-central Mediterranean, including their interactions with vulnerable marine ecosystems; and v) round sardinella in the eastern Mediterranean. The Committee also agreed on the technical soundness of three FRA proposals for the Bari Canyon, the Ebro Delta margin and the Palmahim Disturbance, to be submitted to the Commission. At the regional level, the Committee provided advice on the following: i) fishing technology and bycatch, including minimal technical specifications for bottom-trawl nets and the need for targeted pilot projects to investigate possible mitigation measures; ii) data call for the database on sensitive benthic habitats and species and other effective area-based conservation measures for the protection of vulnerable marine ecosystems and essential fish habitats; and iii) advances in the adaptation strategy for climate change. Furthermore, the Committee discussed additional work in support of the GFCM, namely the implementation of the Regional Plan of Action for Small-Scale Fisheries in the Mediterranean and the Black Sea, dedicated research programmes as well as other activities to enhance fisheries management in the region. Finally, the Committee agreed upon its work plan for 2021–2023.

A review of the application of the FAO ecosystem approach to fisheries (EAF) management within the areas beyond national jurisdiction (ABNJ) by Fletcher, W.J. Pdf

The publication documents the results of the review of the level of implementation of the FAO Ecosystem Approach to Fisheries (EAF) by the fisheries management bodies in each of the different ABNJ regions. The review was designed to help identify future activities by the ABNJ Deep Sea Project to address gaps and capacity development and make recommendations to strengthen EAF among deep-sea fisheries management bodies and/or their members. The information to complete the EAF reviews was largely obtained from web-based materials. To assist with the accuracy of these desktop assessments, following initial drafting of each EAF background report and associated EAF assessment, both documents were sent to the respective RFMO secretariats. Comments and/or suggestions provided by the secretariats were then addressed with revised versions of the background reports and review assessments generated. Based on these revised reports, the comparative analyses were finalized and a full report was drafted. Being a desk-top assessment of the level of implementation of the EAF approach by each of the RFMO management bodies, the study had a number of caveats including only being able to measure systems and processes, not outcomes. A more complete assessment of EAF adoption and especially the outcomes would require direct involvement of the various stakeholders, including all relevant management, compliance and scientific bodies, contracting parties (CP), non-contracting parties (NCP), vessel owners, crews, non-governmental organizations (NGOs), etc.

Report of the First meeting of the WECAFC/OSPESCA/CRFM/CITES/CFMC working group on shark conservation and management, Bridgetown, Barbados, 17-19 October 2017 by Food and Agriculture Organization of the United Nations Pdf

The First meeting of the WECAFC/OSPESCA/CRFM/CITES/CFMC Working Group on shark conservation and management was held in Barbados on 17-19 October 2017. The meeting was attended by 30 shark fisheries experts from 15 WECAFC member countries and partner agencies. The meeting recognized the decline in various shark and ray stocks in the Caribbean region, as well as the need to conserve the threatened species among them. The meeting stressed the importance of harmonizing conservation and management measures with various international and regional conventions for the protection of these often-migratory species, as well as with measures by regional fisheries management bodies in the Atlantic. The fisheries experts recommended amongst others that the countries in the region should prohibit the removal of shark fins at sea and require that all sharks be landed with their fins naturally attached through the point of first landing of the sharks. The experts recommended the prohibition of targeted fisheries for iconic species, such as whale sharks, sawfishes and manta rays. The experts worked on a regional shark stocks and fisheries status assessment and a Regional Plan of Action for the conservation and management of sharks and rays in the WECAFC area.
