"It is the only relic of the 9th-10th century found during underwater research in Poland" - explained Dr. Krzysztof Radka, head of underwater research.
The trap is preserved in good condition. Inside it were the remains of caught fish - according to preliminary calculations, there were more than 4,000. Originally, the fish-pot resembled a narrow, oblong, pointed basket with length of approx. 1.6 m. The trap recovered by archaeologists from Toruń was made of wicker. At the time of discovery it was between parts of a mediaeval bridge, which confirms its distant origin.
By using a water ejector (sediment removal device), the researchers managed to expose the fish-pot and then make full drawing and photographic documentation underwater, even though their activities were difficult due to the limited visibility underwater.
