Summary: | Eels, due to their mysterious life cycle and appearance have long fascinated scientists and fishers alike. In Estonia, similarly to the rest of Europe, eel populations have faced dramatic changes over the last decades, giving researchers a tough task to find out the factors behind these changes. My thesis focused on different aspects regarding the fisheries and welfare of eel in Estonian coastal and freshwater habitats. We studied a long-time series of commercial landings, scientific surveys, restocking efforts, and environmental variables, to shed light on the dynamics of these mysterious creatures. One observation from our investigation is the decline in both commercial and recreational landings of eels along the Estonian coast since the 1970s where data was available. This trend is consistent with a broader pattern seen all across Europe. However, with the fall of the Soviet Union at the beginning of the 1990s there was a sudden growth in eel landings on the Estonian coast. This was most probably due to ... |
