Abstract: BACKGROUND: Over the last ten years, Brazilian fish farming has become more focused, resulting in the development of genetic improvement programmes (GIP) for two South American species Colossoma macropomum (tambaqui) and Pseudoplatystoma reticulatum (cachara). OBJECTIVE: To describe the action plan used for setting up the GIP and to detail the germplasm bank composition. MATERIALS AND METHODS: Semen of both species was collected, frozen and transported between locations in Brazil. To start the programme, full and half-sib families of both species were established from 120 males and 60 females. RESULTS: New species-specific protocols for semen cryopreservation s were established of value to commercial application in fish farming. CONCLUSION: Germplasm banking has enabled the exchange of biological material and reduced the overall GIP costs. Germplasm banking can be very important to the dissemination of the selected genetic material of these species among fish farmers. © CryoLetters.
