The objective of this research was to determine the effect of group size on pig performance. A field study was carried out during 15 months. The building had 52 pens in total, which housed grower pigs to 35-38 kg body weight. During the first 8 months the average number of animals was 726. During the time of most significant decrease of performance in months 9 and 10 the average number went up to 751 animals. A reduction in total feed intake was observed during months 9, 10 and 11 and the average consumption of compound feed per animal and day dropped to 1.68, 1.32 and 1.09 kg. Consequently the weight gain decreased to 615, 535 and 505 g, respectively. The example showed the negative influence of overstocking of grower pigs on the essential performance indicators, such as weight gain, compound feed consumption per feeding day and feed conversion. The number of animals in pens should be decided on the basis of stocking density which influence positively performance. The size of the lying area for this particular age group and this particular building should be between 0.48 and 0.51 sq m per animal.

The aim of the study was to determine the impact of various photoperiods and stocking densities on the growth and survival of narrow-clawed crayfish larvae. The four-week rearing period was carried out in 50 dm³ tanks in a closed recirculating system. The tanks were stocked with larvae two weeks post hatch with an average body length of 11.2 ± 0.9 mm (TL) and weight of 32.3 ± 2.5 mg. There were three stocking densities (300, 600, and 1200 specimens m⁻² ) and two photoperiods (groups L - 24-hour illumination and groups D - 24-hour darkness). The crayfish were fed ad libitum every 12 hours with granulated feed (45% protein, 6-12% lipid). The experiment indicated that photoperiod had a significant impact (P < 0.05) on the crayfish survival rate, while stocking density impacted growth. Crayfish survival was almost two times higher with 24-hour illumination than it was with 24-hour darkness at each of the stocking densities. The survival and the growth rate of crayfish decreased as the initial stocking density increased. The final biomass of the crayfish stocks reared in 24-hour darkness was similar for each of the stocking densities applied, but the biomass of stocks reared with 24-hour illumination increased along with the stocking densities used. This indicates that it is possible to apply initial densities even greater than 1200 _2 specimens m⁻² during crayfish rearing with 24-hour pond illumination.
