Metod för beräkning av svensk sjömatskonsumtion

• Method for calculation of Swedish seafood consumptionRobust statistics on how much and which seafood is consumed in Sweden are important for calculations of intake of both desired and undesired substances through seafood, as well as for mapping and forecasting the environmental footprint generated by consumption. Based on three previous reviews summarizing production and trade statistics to estimate Swedish seafood consumption per species and production method (fishing/ aquaculture), a method has been developed for calculating seafood consumption. Previous reports have provided valuable insights, since the Swedish Board of Agriculture does no longer publish data on Swedish seafood consumption in the same way as for other foods. Focusing on the most recent review, which represents the current state of knowledge and the latest statistics, the purpose of this report is to describe in detail, step by step, the method used for calculating Swedish seafood consumption. The calculation is based on public statistics on the volume of imports, exports and production in aquaculture and fisheries, which when needed was complemented with information from other sources. The method description includes where data is found, how it is downloaded, processed, categorized and how the different datasets were later combined to provide an overall picture of Swedish seafood consumption. Finally, knowledge gaps and the need for supplementary data collection is described. The work on this report has revealed that there are still considerable deficiencies and data gaps in the public production and trade statistics. For instance, landings by foreign commercial fishing boats as well as landings of certain species in recreational fishing are not presented. Production data of certain species in aquaculture may also be lacking, due to confidentiality, and requires alternative strategies to be obtained. In addition, available statistics on herring and sprat are uncertain and difficult to interpret, which is why the calculation of these species requires special treatment. Due to its great importance in both production and consumption, the uncertainties surrounding these species represent an important source of error in the estimation of total consumption. Improvements in production and trade statistics of seafood are important for several reasons and it is important that a future method for public consumption statistics is harmonized with that used for other foods, to enable comparisons. Using alternative and varied ways to fill data gaps from year to year obstructs reliable calculations and comparisons – over time and with other product groups. To ensure a sustainable increase in seafood production and consumption, improved transparency through the whole value chain is of considerable importance – not the least to understand which seafood species that could increase in a sustainable way.
