“…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.…”

“…The polymorphism model refers to there being a combination of resident individuals and nomadic individuals within a population, while the tourist model refers to temporary residence of individuals, with periodic nomadic behaviour. It has been questioned whether these patterns are representative of fish movement or an artefact of the tagging strategy (Attwood and Bennett 1994;Maggs 2011). Most studies provided discussion on the distribution of recapture effort, which could potentially mask movement patterns.…”

“…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.…”

“…From this review, it was evident that 25 % of the studies surveyed had coverage in marine or estuarine protected areas (MPA/EPA). While the conservation benefits within the boundaries of a protected area have been well established locally (Bennett and Attwood 1991;Kerwath et al 2008;Venter and Mann 2012;Maggs et al 2013a) and internationally (Roberts 1995;Halpern and Warner 2002;Halpern 2003), the benefit of protected areas to adjacent fisheries is less clear (Hilborn et al 2004;Sale et al 2005 but see Kerwath et al 2013b). As such, many fish movement studies within South African MPAs have focused on the movement patterns of fish in relation to protected area boundaries (Attwood and Bennett 1994;Cowley et al 2002;Attwood and Cowley 2005;Attwood et al 2007;Kerwath et al 2007aKerwath et al , 2009Hedger et al 2010;Mann 2012;da Silva et al 2013b;Maggs et al 2013b).…”

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.

“…Fully protected no-take MPAs displace fishing effort from an area, thereby providing resident marine species with a refuge from fishing (Sobel and Dahlgren 2004). In South Africa, as in many other parts of the world, overexploited fish species have often been found to be more abundant and of a larger mean size in areas where they are protected from fishing (Buxton and Smale 1989;Attwood 1991, 1993;Buxton 1993;Garratt 1993;Cowley et al 2002;Halpern and Warner 2002;Götz et al 2009;Maggs et al 2013a). Population recovery within the boundaries of a no-take protected area can provide insurance against management failure in fished areas (Bohnsack 1990(Bohnsack , 1996 and, from a fisheries perspective, can lead to replenishment of nearby fished areas through density-dependent spillover of post-settlement fishes and seeding of eggs and larvae (Bohnsack 1996;Russ 2002;Sale et al 2005;Harrison et al 2012).…”

ABSTRACT1. Many marine protected areas (MPAs) around the world are 'paper parks'. A key factor contributing to their ineffectiveness is non-compliance with the rules in place.2. This paper contributes to the existing academic discussion on 'paper parks' by drawing on critical regulation scholarship to develop a theoretical framework to assess and address compliance gaps in MPAs.3. The theoretical insights are then explored using a case study of the second largest Italian MPA (the 'Penisola del Sinis-Isola di Mal di Ventre'), employing a multidisciplinary perspective built on both biological and socio-legal expertise.4. The biological study consists of a review including existing unpublished data on biological resources in the MPA coupled with new analyses on the effects of sea urchin harvesting restrictions. The socio-legal research consists of the analysis of primary qualitative research in the form of semi-structured interviews conducted with key stakeholders at the local and regional level in 2014, followed by two workshops (one with stakeholders and one with the general public) in 2015 to discuss the research findings collectively.5. The results show that the Sinis MPA is not achieving its conservation goals, primarily because of actors' noncompliance with the rules. The interviews with key stakeholders reveal a number of interlinked social, normative and calculative motivations at the basis of non-compliance. Policy solutions are then offered.6. This study offers a novel analysis on 'paper parks' that may be applicable to other MPAs experiencing similar compliance issues.
