The presentation was a customary payment of fish. All occurrences except one were in Cambridgeshire, the exception being in the neighbouring county of Huntingdonshire. It is unclear, therefore, whether this is a localised custom or a vocabulary peculiar to the area.
At a later date, customary presentations of food were common on manors in many parts of the country; presentations of fish may have been a local variant of such customs, appropriate in fenland areas.
For these customary presents of food, see N. Nielson, Customary rents (1910).
