   Sammanfattning : The Baltic Sea is a frontrunner in ecosystem analysis and assessment, which have been used also in multispecies fisheries management advice. In the Baltic Sea, the multispecies assessment and management advice have been focused on the pelagic interactions between cod (Gadus morhua), sprat (Sprattus sprattus) and herring (Clupea harengus), by virtue of their well-known ecology.

3. 2. Otolith morphology of sprat (Sprattus sprattus) along the Swedish west coast

   Master-uppsats, SLU/Dept. Of Aquatic Resources

   Författare :Francesco Saltalamacchia; [2018]
   Nyckelord :European sprat; Otolith; shape analysis; wavelet;

   Sammanfattning : The population structure of sprat (Sprattus sprattus) in the Swedish Kattegat – Skagerrak has been at present not well investigated, and the boundaries between the management unit in this region and the larger stock occurring in the North Sea are also highly uncertain, posing issues to the successful management of the stock in this area. In this study, variations in otolith shape among several samples from the Swedish west coast, southern North Sea and Norwegian fjords north of Bergen were studied to investigate the effectiveness of shape analysis for characterise the population structure in the study area, and evaluate whether differences could be used to assign individual fish to their origin.
