A fast-growing and resilient tilapia genetically selected for high yield in aquaculture
GenoMar 1000 is a genetically selected strain of tilapia with first-class health, survival, growth and fillet yield traits.

Proof of performance
More production cycles per year – better capacity utilization
GenoMar 1000 has a proven growth rate from 22 g to 1,000 g in 114 days in cages, and 121 days in ponds. These results are based on a field trial conducted under commercial farming conditions in Brazil (Figure 1). This superior growth leads to increased productivity as numbers of production cycles per year can be increased (Table 1).
Reduced environmental and disease risks
The fast growth entails a reduction in the number of farming days and less exposure time to infections and environmental risks.
Increased survival throughout the life of the fish
GenoMar 1000 has demonstrated an average survival rate from stocking to harvest of 95.2% (22 g – 1350 g) in cages and 93.4% (22 g – 1,196 g) in ponds in the referred Brazilian field trial (Figure 1).
Animal welfare
The high survival rate of GenoMar 1000 reflects improved animal welfare through reduced mortality and enhanced health.
Uniformity
GenoMar 1000 has shown high uniformity at harvest in cages and ponds. At a target weight of 1000 g, 74% of the fish in cages and 75% of the fish in ponds were within the weight category 850-1150 g (Figure 1).

Figure 1. Growth development, final survival and uniformity of GenoMar 1000 compared to a local commercial strain in a field trial in Brazil. The results presented are an average of two cages with a 50/50 mix of the two strains (common garden design), with individually tagged fish.
