The experiment was conducted to investigate the effects of artemia enriched with lipid emulsions containing highly unsaturated fatty acids on growth and survival of juvenile freshwater crayfish Astacus leptodactylus. Juvenile crayfish were fed artemia enriched with commercial emulsions (red pepper and olio ω3) and un-enriched artemia (control). The highest eicosapentaenoic acid (EPA) level was ...

All organisms are probably exposed to different types of electromagnetic fields (EMFs). This study is an attempt to evaluate the effect of extremely low-frequency EMFs (50 Hz) on some growth parameters and survival rate of common carp fingerling. The fry (n = 120, averaged 16.76 ± 0.88 g in initial weight) was exposed to ELF-EMF at four intensities of 0.1, 0.5, 1 and 2 mT only once for 2 h and ...

  The effects of water current increment on rainbow trout ( Oncorhynchus mykiss ) culture were investigated   during a 35 day experiment. Fish weighing 5.5 g were stocked in aquarium tanks. Four different water speeds (0, 3.5, 7, 10.5 cm/s) were provided for each treatment in three replicates. These different currents water were provided by reusing outlet water of each culture unit...
