S. marginata is a batch spawner, releasing a minimum of 3 batches of eggs per year. Relative fecundity is high (34000 eggs per year I kg) and this coupled with the protracted spawning season would make it possible to obtain adequate numbers of juveniles (for farming) for approximately five to six months of the year. Comparative analysis of the biological characteristics in relation to other soles farmed elsewhere in the world suggests that S. marginata is a suitable candidate for marine fish culture in South Africa.]]> Wed 12 May 2021 20:59:20 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:5337 Wed 12 May 2021 20:26:41 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:5081 Wed 12 May 2021 20:19:30 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:2360 Wed 12 May 2021 20:00:48 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:3099 Wed 12 May 2021 19:42:01 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:5914 Wed 12 May 2021 19:23:16 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:7050 Wed 12 May 2021 19:10:53 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:4805 Wed 12 May 2021 19:02:20 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:9267 Wed 12 May 2021 18:50:29 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:2724 Wed 12 May 2021 18:40:03 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:11081 Wed 12 May 2021 18:39:08 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:7029 Wed 12 May 2021 18:33:17 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:7039 Wed 12 May 2021 18:17:29 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:5007 Wed 12 May 2021 17:58:05 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:553 Wed 12 May 2021 17:42:05 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:10931 Wed 12 May 2021 17:15:21 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:9489 Wed 12 May 2021 16:48:15 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:688 Wed 12 May 2021 16:36:21 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:10998 Wed 12 May 2021 16:34:40 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:8961 Wed 12 May 2021 16:34:08 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:559 Wed 12 May 2021 16:24:26 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:7032 Wed 12 May 2021 16:19:52 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:10985 Wed 12 May 2021 16:16:48 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:11062 Wed 12 May 2021 16:11:06 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:7036 Wed 12 May 2021 16:06:00 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:8143 Wed 12 May 2021 15:52:03 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:3935 Wed 12 May 2021 15:49:47 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:2725 Wed 12 May 2021 15:48:19 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:5918 Wed 12 May 2021 15:45:05 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:62999 Tue 28 Mar 2023 12:17:53 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:62989 Tue 28 Mar 2023 11:36:05 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:62987 Tue 28 Mar 2023 11:28:52 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:62973 Tue 28 Mar 2023 10:18:59 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:56629 cyclohexenol > trans-cyclohexanediol > cyclohexene oxide > cyclohexene hydroperoxide.

Significant differences (p<0.05) were however observed between reaction times for the experimental techniques. Slower reaction times are most likely due to increased upper body pretension, resulting from the increased hip elevation seen for these techniques. The results indicate that increased hip elevation may have delayed the initiation of the relevant motor response required to affect an optimal sprint start. Technique 1 resulted in the shortest reaction times, shortest block times, fastest sprint times and greatest sprint velocities for all four techniques. This result was possibly due to the athlete’s experience with, and repeated use of, this technique. The experimental techniques therefore provided no added advantage over the subject’s preferred starting technique and did not significantly optimise sprint starting performance. The results show that modification of the front knee angle had no significant influence on sprint starting performance and sprint running ve locity or acceleration patterns up to 50m. Using Pearson’s Correlation Coefficient to determine the strongest correlations between isokinetic knee strength and sprint starting performance, analysis revealed that the strongest relationships were found between sprint starting performance expressed as acceleration and isokinetic knee strength expressed as relative peak torque and absolute peak torque. For Technique 1 the strongest correlation was found between acceleration (30m - 40m) and relative peak torque as measured at a test speed of 240°/s (r = 0.62). For the remaining experimental techniques, the strongest correlation was found between acceleration (10m - 20m) and relative peak torque as measured at a test speed of 60°/s (r = 0.53) for Technique 2, between acceleration (40m - 50m) and peak torque measured at a test speed of 60°/s (r = 0.72) for Technique 3, and between acceleration (0m - 5m) and peak torque as measured at a test speed of 240°/s (r = 0.71) for Technique 4. These results suggest that isokinetic muscle strength does not correlate strongly with sprint starting performance and that additional factors, such as neuromuscular organisation and muscle fibre typing, possibly make a greater contribution to optimal sprint starting performance.]]> Thu 13 May 2021 08:47:12 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:5701 Thu 13
