The problem of insufficient quantities and high temperature of water during the summer months (1st July to 1st September 1998) in the fish ponds of Eastern Croatia had as a consequence a reduced production (growth) of fish in the fish ponds. Air temperatures higher than 30 °C and warming up of water were the causes of a larger food consumption and smaller growth, as well as of an increase in expenses connected with pump stations and with aeration of the water, and they have also caused a higher or lower death-rate of fish and a deterioration of the health condition of the fry setting. All this has resulted in a smaller growth of fish in fishponds. On the 825 ha of fish ponds with one year old fingerlings in Eastern Croatia, as well as on the 1,208 ha of fish ponds with two year old fingerlings and 2,637 ha of fish ponds with fish for the market the production was on the average reduced as follows: in one year old fingerlings it was reduced by 36,0%, in two year old fish by 30,0% and in the fish for the market by 27,5%. On the basis of the total assessment of the reduction of growth and of a smaller number of kilograms of produced fish founded on the average sale value of fish the fish ponds recorded a ++drop in realization which - converted into money - was reduced by 24,230.079,00 kn. These indicators lead to the conclusion that the influence of high summer temperatures had the effect of natural disaster for fish producers in Eastern Croatia and therefore they have a justified right to demand compensation for the damage they have suffered.
