“…The independent published mark-recapture studies, from where this data originates, often provide higher resolution than that provided by the ORICFTP. Indeed, Maggs et al (2013b) showed that the 95th percentile of recorded movements of four species ranged from 270 to 748 m. In the same study, some individuals of the same four species undertook longrange movements ranging from 3 to 1059 km. Attwood and Cowley (2005) reported similar results among 2174 recaptured Dichistius capensis.…”

“…Similar fish monitoring programmes were initiated in the Tsitsikamma National Park in 1990 (Brouwer 2002;Cowley et al 2002;Brouwer et al 2003;Attwood and Cowley 2005;Kerwath et al 2007a;Watt-Pringle 2009), in the St Lucia Marine Reserve in 2001 (Mann 2012) and Goukamma MPA in 2001(Kerwath 2005Kerwath et al 2007aKerwath et al , 2008. More recently, fish tagging programmes affiliated to the ORICFTP have commenced in the Pondoland Marine Protected Area in 2006 (Maggs 2011;Maggs et al 2013b), in the Ngqura Harbour in 2007 ( ML Dicken, KZN Sharks Board, pers. comm.…”

“…Across a range of families, within the Osteichthyes and elasmobranchs, these accounts most often reported a high degree of restricted or ''zero'' movement, with infrequent occurrences of long range movement (Bennett 1993;Griffiths 1996;Cowley et al 2002;Brouwer et al 2003;Attwood and Cowley 2005;Dudley et al 2005;Dicken 2011;Maggs et al 2013b). This phenomenon has been described as partial migration-the occurrence of resident and migratory behaviour within a coexisting animal population (Kerr et al 2009).…”

“…Movement within estuaries is constrained and particularly suited to fine-scale acoustic tracking, which has focused predominantly on spotted grunter Pomadasys commersonnii (Kerwath et al 2005;Naesje et al 2007;O'Connell 2008;Childs et al 2008a, b, c) and to a lesser degree on white steenbras Lithognathus lithognathus (Bennett et al 2011 and dusky kob Argyrosomus japonicus (Cowley et al 2008;Naesje et al 2012). Although logistically more difficult, fine-scale habitat usage has also been investigated to a lesser degree in the marine environment with both acoustic telemetry (Hissmann et al 2006;Kerwath et al 2007b;Jewell et al 2012;Kock et al 2013) and conventional mark-recapture (Attwood 2002;Kerwath et al 2007a;Maggs 2011;Maggs et al 2013b). Fine-scale habitat usage has most often been discussed in the context of residency and in association with estimations of home range with the objective of evaluating protected area sizing and spacing.…”

Unprecedented concern over the biological effects of over-exploitation, together with rapid technological advances in biotelemetry, have provided the impetus for much research, on a global scale, into the movement of marine animals. We reviewed 101 marine and estuarine fish movement studies from southern Africa, published from 1928 to 2014, with the aim of synthesising research trends and findings. Trends showed an increasing emphasis on fish movement research in publications in the sub-tropical and warm-temperate biogeographic regions along the south and east coasts of southern Africa. Although 63 % of publications featured only marine studies, research into fine-scale habitat use in estuaries has been on the increase, concomitant with increasing accessibility of biotelemetry. Overall, 26 families were identified in the surveyed literature with regionally endemic sparids featuring in 32 % of the publications. Ten movement themes were identified in the surveyed literature, including broad-scale movement patterns, which featured in 68 % of studies, followed by fine-scale habitat usage (33 %) and protected areas (26 %). The most prominent phenomenon, emerging from this research, is that of partial migration, which describes the occurrence of resident and migratory behaviour within a coexisting animal population. Substantial progress has also been made in unravelling the complexities of fine-scale habitat usage in marine reserves and in estuaries. While this knowledge has enabled more effective management of South Africa's multi-user, multi-species fisheries, focus should now be directed at improving our understanding of the commonalities in movement behaviour, the associated driving forces behind this behaviour and the nature of movement across reserve boundaries.

“…The majority of eggs are fertilized and scattered above coral and rocky reefs from northern locations, and the developing larvae drift southward influenced by the strong Agulhas Current in this region (Garratt, 1985a, b). Juveniles settling out to the south of Park Rynie, where no spawning takes place, are believed to move northward later in life to reproduce (Maggs et al, 2013). Accordingly, average sizes were found to be higher in the northernmost location of Richards Bay.…”

Sex change and effective population size: implications for population genetic studies in marine fish

et al. 2016

Large variance in reproductive success is the primary factor that reduces effective population size (N e ) in natural populations. In sequentially hermaphroditic (sex-changing) fish, the sex ratio is typically skewed and biased towards the 'first' sex, while reproductive success increases considerably after sex change. Therefore, sex-changing fish populations are theoretically expected to have lower N e than gonochorists (separate sexes), assuming all other parameters are essentially equal. In this study, we estimate N e from genetic data collected from two ecologically similar species living along the eastern coast of South Africa: one gonochoristic, the 'santer' sea bream Cheimerius nufar, and one protogynous (female-first) sex changer, the 'slinger' sea bream Chrysoblephus puniceus. For both species, no evidence of genetic structuring, nor significant variation in genetic diversity, was found in the study area. Estimates of contemporary N e were significantly lower in the protogynous species, but the same pattern was not apparent over historical timescales. Overall, our results show that sequential hermaphroditism may affect N e differently over varying time frames, and that demographic signatures inferred from genetic markers with different inheritance modes also need to be interpreted cautiously, in relation to sex-changing life histories.
