Biological parameters of Nile tilapia (O. niloticus) in various locations from literature. The parameters are: predicted asymptotic length (L∞, Standard and Total Length, italics values are recalculated values), growth coefficient K, growth performance index φ’, and hypothetical length at which age is zero t0, the exploitation rate E, total coefficient of mortality Z, natural mortality M, and fishing mortality F.
