Summary
Establishing a germplasm bank for South American fish, Colossoma macropomum and Pseudoplatystoma reticulatum, facilitated genetic improvement programmes (GIP). This approach reduced costs and aids in disseminating valuable genetic material to fish farmers.
Area of Science:
- Aquaculture
- Animal Genetics
- Reproductive Biology
Background:
- Brazilian fish farming has intensified over the past decade.
- Genetic improvement programmes (GIP) were initiated for tambaqui (Colossoma macropomum) and cachara (Pseudoplatystoma reticulatum).
Purpose of the Study:
- To outline the strategy for establishing GIP.
- To detail the composition of the germplasm bank.
Main Methods:
- Semen collection, cryopreservation, and transportation protocols were developed for both species.
- Establishment of full and half-sib families using 120 males and 60 females.
Main Results:
- Species-specific semen cryopreservation protocols were successfully developed.
- These protocols are suitable for commercial application in fish farming.
Conclusions:
- Germplasm banking facilitates biological material exchange and lowers GIP costs.
- It is crucial for disseminating selected genetic material to fish farmers, enhancing South American fish production.
