The length-frequency distribution analysis revealed that the three species had the same growth rate regardless of habitat type. However, females grew faster than males. An investigation of reproductive biology showed that the three species have low fecundity and they are asynchronous spawners, with a breeding peak during August and September period. Furthermore, the length-fecundity relationships for L. ''pinkhead'', and 0. argyrosoma "red" indicated that fecundity was more closely related to length in the south eastern side than in the south western side. Based on the above characteristics of L. ''pinkhead'', 0. argyrosoma "red" and C. cf virginalis, and the substrate types, it was strongly suggested that the existing sanctuary (lightly fished) in the south eastern side of the lake could immediately be enlarged to conserve the fish stocks, favourable substratum and aquatic animals that may be of tourists concern.]]> Wed 12 May 2021 20:03:44 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:5233 Wed 12 May 2021 18:40:31 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:5510 Thu 13 May 2021 07:44:17 SAST ]]>
