Tridge summary

A research project at the University of Debrecen's Faculty of Agriculture, Food Science and Environmental Management in Western Europe is aiming to bring back the perch, a premium fish species, into mass production in aquaculture. The project focuses on improving the species' housing and feeding conditions, and developing ways to utilize the run-off water from the fish farms. The research also includes the use of a self-developed caged fish farming system for post-rearing the perch in lakes, and the production of insect protein-based feeds to replace fishmeal. The effluent from the fish production is recycled for the production of planktonic food organisms and aquaponic plant production, making the system more resource-efficient and sustainable.

In Western Europe, perch is an absolute premium product. Due to its white, plate-like, low-fiber meat, it is very popular among fish consumers, its quality also competes with perch and sea bass, however, it is rarely put on the table at home - writes hirek.unideb.hu. “The perch used to be found in large numbers in domestic waters, but later it was gradually reduced. The aim of our now closed program was to bring this species, which can be considered new in aquaculture, into production, to develop the related production technology, to improve housing and feeding conditions, and to explore the utilization possibilities of the resulting so-called run-off water. Today, perch is mostly used as a by-product in fish farms, and its introduction into intensive production would be justified by the needs of the food market and the fishing industry, ”said Fehér Milán, a researcher at the University of Debrecen's Faculty of Agriculture, Food Science and Environmental Management (MÉK). “In ...
