Data preparation to inform assessment and management approaches in data-limited fisheries

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.

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.

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
