The tradition of fish farming in the Bechyně area dates back to the 16th century.
Jakub Krčín lived in Bechyně between 1570 and 1596, during the time when Petr Vok purchased Bechyně from Jindřich of Švamberk as a relatively consolidated estate. For nearly 10 years (until his late marriage), he did not make any significant renovations to the Renaissance castle. It is believed that he may have been prompted to do so only after the fire in 1578. His strained relationship with his older brother Vilém, the ruler with absolute power at the time, influenced his debts and lifestyle. While Petr Vok was independent in Bechyně, except for the economic management, which was under the authority of Regent Krčín, it could not have pleased him when Vilém, through Krčín, communicated that as ruler, he had the right to take away the estate whenever he deemed it appropriate. Although taking Bechyně away was not so simple anymore, as Petr had already purchased it and it was no longer entrusted to him. He also couldn't have been happy when Vilém sent Krčín to him with the message that anything Krčín told him should be trusted as if Vilém himself had said it.
It is important to realize that Petr Vok carried out many projects in Bechyně where Krčín, as an expert, was indispensable. These projects primarily included the water supply system, which involved capturing springs and constructing ponds. The need for water for the town, the castle, and the monastery was significant. A brewery had already been established at the castle in 1444, and at the monastery, cloth was made and the production of hoods for the Franciscans throughout the province was introduced. The town needed water not only for the livelihood of its residents but also for the town's fortifications, which were partially filled with water so that "in the case of an unfortunate event, the town could be supplied with enough water."
As chronicler J. Šatra mentioned in 1912: "From all the signs, it can be inferred that behind the current barns, where the estate fields spread to the left of the Trubný pond, there was a large pond, which is still referred to today as the 'Old Pond,' on which a part of the dam is still known, and from there it is highly likely that the town was supplied with water."
