  In our study, the comparison of 5 ml straw and 10 ml cryotube during sperm cryopreservation in a Hungarian carp landrace (Cyprinus carpio carpio morpha accuminatus) was carried out. Three different dilution ratios (1:1, 1:4 and 1:9) were also tested using the cryotube. A significantly higher pMOT was recorded using the cryotube in comparison with the straw. VCL and STR were similar in both groups. Cryopreservation had a negative effect on pMOT and VCl using the cryotube and also the straw where, STR was not reduced significantly. An increasing tendency was observed using higher dilution of sperm during cryopreservation; however, significant difference was not recorded between the three groups. VCL and STR were similar in all groups. Cryotube was applicable for the sperm cryopreservation of the Hungarian carp landrace. However, the standardization for the freezing method specified for this volume is recommended. The different dilution ratios needed be tested also during fertilization.

  In 2002, the area which was monitored according to the requirements of organic farming numbered 103 thousand hectares in Hungary (this is some 1.7% of all cultivated land) and almost 1000 plants producing organic products were inspected. It is a realistic assumption, when considering these data, that within a short period time the area used for organic farming will reach the optimal 600.000 hectares.
  Contrary to overproduction in the EU – cereals, maize and other plants – organic products can be sold in unlimited quantities. Practice also indicates, that 90% of Hungarian certified organic products are sold in EU and Swiss markets.
  Thus, it is important to label Hungarian products according to EU standards. This way standard quality products can be sold easier and by increasing their income, manufacturers can contribute to the improvement of the environment.
