How were fishponds introduced, farmed and spread in Scandinavia and the Baltic Region in early modern times? What was their economic, social and religious importance? Which fish species were significant and why? This book uncovers a long, now broken, tradition that barely left traces in the written record or physical environment. Its broad and multidisciplinary scope highlights the situation from medieval times until the late nineteenth century. Besides Scandinavia and the Baltic States, insights from England are also introduced. Several socio-cultural domains have been identified: late medieval monastic fishponds; late medieval aristocratic fishponds associated with castles and manors; seventeenth and eighteenth century ponds rectory ponds as well as urban ponds from the seventeenth century to the nineteenth century.
