ABSTRACT. This study proposes solutions developed during a project to improve breeding and rearing conditions in existing trout farms that could be implemented with the least possible disturbance to farming. The aim of the work was to identify the needs of trout farms in terms of adapting existing technological solutions to individual conditions. Problems that are addressed include low trout resistance to oxygen deficits and susceptibility to stress from manipulation during sorting, weighing, and loading. The solutions presented include: a comprehensive pathomorphological fish assessment method to determine the impact the environment and technology have on fish health; the use of oxygen probes and Archimedes screws with sorting devices.
Key words: rainbow trout, breeding technology, liver pathomorphology, Archimedes screw, oxygen probe
