Main research areas of the laboratory:
1) controlled fish reproduction is focused on optimization of methods for obtaining viable fish gametes by adjustment of water conditions with or without hormonal preparations usage in commercially important fishes (common carp, tench, grass carp, pike-perch, sturgeons, coregonids, salmonids), fishes new to aquaculture (perch, African sharptooth catfish, Heterobranchus longifilis, sturgeons). Research is supported by the evaluation of release dynamic of sex hormones during pre-spawning and spawning period. One of the current experiment is focused on comparison of growth rate and onset of sexual maturity in brook trout, arctic charr and their hybrid (including impact on mortality in marketable fish). In this context, different types of photostimulation are tested primarily. The laboratory is also studying controlled reproduction and quality of gametes after artificial reproduction in tropical ornamental fish species.
The laboratory performs commercial feeding trials, or feed additives, including evaluating of feed coefficients provides follow-up tests (hematology, histology, etc.). The laboratory has broodstock of catfishes (Clarias gariepinus and Heterobranchus longifilis) and deliveries advanced fry of this species (or interspecific hybrid) for fish farmers.
In addition, the researchers provide consultancy services (for professionals and practice), education at FFPW USB (including supervising of bachelor's, master's and doctoral theses), and workshops in the above mentioned areas. Members of laboratory provide or participate in teaching of vocational subjects (Tropical Ornamental Aquaculture, Culture of Salmonids, Culture of Warm-water Fishes, Intensive Aquaculture, Recirculating Aquaculture Systems, Controlled Reproduction of Fish, Basics of Aquarium Fish Biology) in Czech and English language, including organization of thematic excursions.
The laboratory cooperates with Czech and foreign universities, research institutions, and companies with similar aims, focusing not only on intensive fish farming, but also on designing of equipment for fish farming in recirculation aquaculture systems.
