"The High Rock Spring tui chub is presumed to have gone extinct following the “inevitable escape” of the Mozambique tilapia (Oreochromis mossambica) from a screened rearing area 100m downstream from the High Rock Spring source. The tilapia competed with and/or preyed upon the tui chubs (Moyle et al. 1995, p. 144)."
