Tilapia Growth Chart
About 4 to 6 weeks from hatching, fingerlings should be about 1 gram, if culture temperatures are in the mid 80s (degrees F). The following table assumes that warm temperature range, moderate to aggressive feeding, in terms of percent biomass per day, and also assumes that fish stocking densities do not exceed 80kg per cubic meter (about 2/3rds pound per gallon)
This is the target average weight of the individual fish.
