Net fitness components for risk assessment. (A) All impacts of genetic modification on physiology and survival rate can be simply measured as the proportion of juvenile fish surviving to sexual maturity. (B) Age at sexual maturity determines the number of possible generations per time. (C) Differential mating success (sexual selection) is a strong selective force of evolution in natural populations. (D) Relative fecundity and fertility determine the number of offspring per mating pair. (E) Adult viability determines how often a pair can repeat the mating process
