| Comments: | Introduced by Alvin Seale in 1905. Widely diffused in streams in all islands (Ref. 6348). Fish found in stable reservoirs had fewer offspring, lower reproductive allocations, were thinner, shorter and weighed less than fish from fluctuating reservoirs. Apparently, founder effects contributed to the divergence of all stocks while drift contributed to divergence among fluctuating stocks (Ref. 10422). Over 420 individuals have been introduced (Ref. 1972). Ref: Seale, A., 1917 | ||||
