The transport of 3-Spot tilapia broodstock from KIFI to Onavivi Inland Aquaculture Center (OIAC) took place on 17 March 2015. The fish arrived at Onavivi IAC on the 18th of March 2015. Two stains of broodstock made the journey. One stain from the Kavango river consisting out of 210 fish (male and female) and one strain from the Zambezi system consisting of only 16 fish. The team from Onavivi collected the Zambezi broodstock from Katima on the 16 th of March and then proceeded to KIFI where the fish were kept overnight in sement holding tanks before reloading them along with the Kavango strain in seperate tanks for the long journey.

These 2 strains of 3-Spot tilapia (Oreochromis andersonii) will join a strain from the Kunene system at Onavivi IAC and will undergo a selective breeding programme for the development of  improved 3- Spot tilapia for commercial production purposes.

The mortality during the transport was quite high with 99 fish of the Kavango strain dead and luckily all 16 of the Zambezi strain surviving. This means that there are 111 of the Kavango strain remaining. In total there are 77 female and 34 male Kavango brood stock surviving and 9 male and 7 female from the Zambezi strain.
