SEAwise review of health impact of different fish and fish sizes

The SEAwise project works to deliver a fully operational tool that will allow fishers, managers, and policy makers to easily apply Ecosystem Based Fisheries Management (EBFM) in their fisheries. This SEAwise report evaluates the health impacts of different fish species. The consumption of different types of fish is part of a healthy diet, where the health impact depends on the nutrient content of fish as well as possible contaminants. Information on these aspects were collected from institutional and governmental sources and quality assured. National nutritional databases were consulted to obtain regional data to respond to the case studies approach of the SEAWISE project. When data was not available from national databases, a literature review was conducted to attain complementary data. As the raw data from different sources was in various formats and structures, the data was subsequently adapted to ensure unit equivalence and homogeneous descriptions to allow combination and analyses of all the information.The health impacts of nutrients and contaminants content in fishes depends on the person’s requirements. Certain population groups can have increased nutritional needs, e.g. pregnant or elderly people, and citizens of certain countries can present specific nutritional deficits. To determine the potential health impact, an in depth analysis of European nutritional needs was therefore conducted.The combination of the fish nutritional and contaminant contents and the nutritional requirements and characteristics of the populations groups enabled SEAwise to design a fish recommendation system. The system is based on a ranked list of fishes that was created in the project and from this, best choices for overall health benefits of each population group was established.More information about the SEAwise project can be found at https://seawiseproject.org/</p

SEAwise Report on review guidelines

This deliverable report provides the framework, guidelines, and specific instructions for systematic reviews to be undertaken with SEAwise. The report also includes pre-registered review protocols for five key systematic reviews focussing on the social effects of and on fishing, ecological effects on fisheries yield, ecological effects of fisheries, spatial management impacts, and evaluation of management strategies. The results of these reviews are reported in subsequent x.1 deliverable reports and will provide a synthesis of foundational knowledge for each of SEAwise’s work packages two-through-six, respectively.  This report contains a brief overview of the motivation for undertaking a series of systematic reviews and the selected framework that is being employed for all reviews across the project. Furthermore, this report provides detailed instructions for carrying out each step of a systematic review which can be applied to both the key SEAwise reviews, but also any other review either within or outside of this project. This includes, descriptions of how important databases function, R-scripts for processing records from databases and approaches to data-management for large collaborative reviews.  Additionally, this report serves as the repository for the search protocols for five reviews. These protocols ensure transparent methods and reduced bias in the searching, screening and data extraction.  The success of the coordination across five large-scale systematic reviews is illustrated in the coherence of the approaches and detailed methods described in this report. This report describes results of the SEAwise project. More information about the project can be found at https://seawiseproject.org/</p

SEAwise Data Management Plan

   This report describes the SEAwise data procedures and guidelines with the aim to increase the awareness about the data collected, processed and stored in the project, to ensure that all relevant data collected and used in the project is available in a well-documented, discoverable, standardised and easily accessible form, to give information on data quality and sampling protocols and, to clearly state the usage rights on the different data and to ensure use and handling of data is in accordance with Regulation 2016/679 of the European Parliament and of the Council on the protection of natural persons with regard to the processing of personal data and on the free movement of such data (General Data Protection Regulation, GDPR).  Sharing research knowledge and data is integral to the SEAwise project and this is attained through implementing the FAIR principles, employing dedicated quality assurance processes and carefully considering ethical aspects of knowledge and data storing and sharing. </p
