“…Over 6000 Acroteriobatus annulatus were tagged in South African sport fisheries between 1984 and 2011, revealing important information such as a maximum distance travelled of 726 km. Yet the tagging of this species was discouraged from 1998 onwards due to it being considered a low research priority (Dunlop et al 2013). …”

“…Other nations currently specifically reporting guitarfish landings include Pakistan, Indonesia, Libya, Benin and Palestine (FAO 2016). Guitarfishes can contribute to local economies through dive ecotourism (African Dive Adventures 2014) and recreational angling (Dunlop et al 2013), and to education as exhibits in public aquaria (Georgia Aquarium 2016). As relatively large and sometimes abundant benthic mesopredators, guitarfish have an important role in the trophic functioning of soft-sediment ecosystems (Kyne & Bennett 2002).…”

Focusing on the most critical conservation priorities to prevent extinctions risks missing declines of lower priority taxa that may become tomorrow's emergency. Sawfishes (5 species) underwent catastrophic but largely unnoticed global declines in the latter part of the 20th century, and are now the subject of intensive research and conservation efforts. Guitarfishes (at least 55 species) share many characteristics with sawfishes: they are shark-like batoids with an often large body, prefer sedimentary habitats in warm shallow coastal waters exposed to intensive fisheries, and have high value fins and good quality meat. Guitarfishes represent a unique element of evolution and biodiversity and are vital components of complex coastal socio-ecological systems. Existing global IUCN Red List of Threatened Species assessments for nearly 60% of guitarfish species are 10 or more years old, and over 70% of species are either in threatened categories or Data Deficient. Recently described taxa not yet assessed include those likely to be at risk of extinction. Severe declines and localised extinctions have already been reported for guitarfishes. In notable contrast to sawfishes, total extinction of several guitarfish species is plausible given small distributions occurring solely in developing or least developed countries where conservation is highly challenging. Furthermore, species identification of guitarfishes is often problematic and they may lack the appeal often needed to promote conservation. To ensure that they do not follow the same trajectory as sawfishes, there is an urgent need for comprehensive and coordinated action on guitarfishes, which in many cases could integrate with sawfish conservation efforts.

“…The widespread use of smartphones (and apps) is an important emerging platform for recreational fishing data collection that will almost certainly grow in utility and importance [60,61]. Perhaps the best known example of citizen science within fisheries research are sportfish tagging programs which have a relatively long history and have facilitated substantial gains in knowledge of key species [62][63][64][65]. Citizen science can involve the monitoring of habitats such as seagrass which are important for harvested species, and the quality of such data when collected using structured survey designs and methods can be high quality [66].…”

Urban Recreational Fisheries in the Australian Coastal Zone: The Sustainability Challenge

Abstract:Recreational fishing is an important wildlife harvesting activity in urban coastal areas, and recreational harvest in these areas can frequently exceed the commercial harvest. Recreational fishing is a key way that many members of the public experience the environment. The activity enhances social capital, promotes respect for nature, provides health benefits and can provide economic benefits to coastal communities. It is also an important driver of the science on aquatic animals and habitats, and an important tangible reason for many members of the public to conserve and protect aquatic resources. Overall, there has been little specific consideration of urban recreational fisheries management in Australia, despite the paramount importance of urban areas as a focus of recreational fishing activity. This paper identifies that in order to maximize individual and societal benefits from recreational fishing, there needs to be a refocussing of management with the aim of being more holistic. Historically, fisheries management in Australia has focused on maximum sustainable yield (MSY) or maximum economic yield (MEY) which is relevant for the commercial fishing sector, but neither of these is directly relevant to recreational fisheries. This paper identifies that Urban Fisheries Management Plans are required that recognize the specific issues associated with urban recreational fisheries. These plans need to coordinate within and between levels of government and have clear management objectives relevant to urban recreational fisheries. Enhanced opportunities for meaningful citizen science can be incorporated at multiple levels within these plans and this can engender public support for environmental stewardship, as well as fill a very important gap in the knowledge base necessary for managing the activity. As urban recreational fisheries are often occurring in highly modified or degraded habitats, a central element of these plans needs to be habitat restoration and this can have broader benefits for aquatic health. Other management tools include habitat creation (e.g., artificial reefs), optimization of coastal infrastructure as fisheries habitat, and stock enhancement. Overall, Urban Fisheries Management Plans represent a necessary evolution of fisheries management to better address the specific challenges of urban recreational fisheries management, and to best ensure that benefits are optimised.

“…ORI recognised the collective value of unreported data and the need to coordinate tagging on a regional scale. At the same time, there was a growing interest among recreational anglers to participate in a cooperative tagging project and in 1984, the ORI Cooperative Fish Tagging Programme (ORICFTP) was established with a wide geographic coverage including South Africa, Mozambique and Namibia (van der Elst 1990;van der Elst and Bullen 1993;Dunlop et al 2013). This programme was aimed specifically at generating information on growth, migration and fishing mortality for use in fish stock assessments.…”

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.
