1. Artificial propagation of zebrafish - included: stripping of females and males, induction of ovulation by: water change, natural factors (eg. existance of males) and hypophysis treatment.

2. Oocyta transplantation - early development stage oocyte from donor females to 'host' females.

3. Fin transplantation - for measuring of genetic distance among individuals.

4. Genommanipulation - inducing androgenesis, gynogenesis and tetraploidity.

5. Sperm cryopreservation.
