The Institute of Ichthyobiology and Aquaculture is a research institution of the Polish Academy of Sciences. The main directions include the study of the biological basis of fish breeding, the development of breeding methods in ponds and controlled conditions, and optimisation of links between fish farming and water management. The Institute has a carp live gene bank of 19 Polish and foreign carp strains. This allows for investigations into genetic aspects of carp selection; improving productive traits and resistance against pathogens. One of the fields of activity is research on carp resistance to diseases. The Institute is involved in several national programmes for improving animal quality and gene preservation. Infrastructure and training: The Institute has laboratory rooms, a conference hall, a centre for fish breeding in controlled conditions, aquarium rooms, 115 experimental ponds over a total area of 48 ha, and a hotel for visiting scientists. The Institute is well prepared as a conference centre and organises summer and semester training and courses for students and for research workers of biology and fisheries.
