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.

"These guidelines aim to help those who design routine data collection programmes, focusing on the relationship between typical questions asked by policy-makers and managers, and the data required for providing reliable answers. Fisheries policy and management objectives, particularly under the precautionary approach, need to be based upon analyses of reliable data. Data are needed to make rational decisions, evaluate the fisheries performance in relation to management activities and fulfil regional requirements. These objectives are achieved using fishery performance indicators. Indicators are used to measure the state of the resource, the performance of fishing controls, economic efficiency, socio-economic performance and social continuity. The primary factor in choosing what data to collect is the link between the necessary operational, biological, economic and socio-cultural indicators and their associated variables. The way in which different data variables are collected needs tobe tailored to the structure of the fishery. The strategy will be strongly influenced by the budget and personnel available, and the degree to which fishers and others co-operate. The programme must identify which variables should be collected through complete enumeration and which can be sampled. Collection methods are influenced by the variable itself, the strategy, collection point and the skill of the enumerator. Once collected, fishery data must be stored securely, but made easily available for analysis, which is achieved through a computer-based data management system, following the basic data processing principles. The implementation of a data collection programme should follow a normal project cycle, developing a new legal and institutional framework as appropriate"--Abstract.

Based on an international symposium and workshop hosted by the University of Hull International Fisheries Institute, this new reference includes expert reviews of the advantages and shortcomings of all current techniques and management strategies used in assessment of freshwater fish stocks worldwide. In addition to the core reports, overview papers present a summary of the current status of our knowledge in each of the major subject areas, with a final chapter appraising present and future perspectives on the concept of stock assessment. All contributions are fully illustrated and referenced. Stock Assessment in Inland Fisheries is likely to become the international, standard reference for all fisheries departments--offering a single source of contemporary and definitive information. Moreover, it is also intended to serve as a course text for students learning about freshwater-fisheries management.

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

This report summarizes the discussions held during the forty-fourth session of the General Fisheries Commission for the Mediterranean and the eleventh session of the Committee on Administration and Finance. During the session, progress in activities related to fisheries, aquaculture, compliance and other strategic activities was reviewed. The Commission adopted 21 binding recommendations and 14 resolutions dealing with fisheries management and conservation, aquaculture, compliance, vessel monitoring and the fight against illegal, unreported and unregulated fishing as well as the GFCM 2030 Strategy for sustainable fisheries and aquaculture in the Mediterranean and the Black Sea. Moreover, the Commission reviewed issues related to its functioning and to the mandate of the GFCM Executive Secretary. Finally, the Commission adopted its programme of work for the next intersession and approved its autonomous budget for 2022 as well as a number of strategic actions to be funded through extrabudgetary resources. The Commission also renewed the GFCM Bureau as well as the mandates of the Bureaus of the Scientific Advisory Committee on Fisheries, the Scientific Advisory Committee on Aquaculture and the Working Group on the Black Sea, and endorsed the new Bureaus of the Compliance Committee and the Committee on Administration and Finance.
