In 2002, work commenced on the development of a new deep-water in close proximity to the port. These preliminary results suggest that port, Ngqura or more commonly known as Coega, located inshore long-lining operations could potentially have a very negative approximately 20 km east of Port Elizabeth. The development of the port impact on the population of smooth houndsharks and perhaps other required extensive dredging of an approach channel and port basin at shark species inAlgoa Bay. the mouth of the Coega River. Environmentalists were split on their views as to how the port may affect the relatively pristine surrounding One of the most surprising discoveries to date was the abundance and waters of Algoa Bay. On the one hand there were concerns that the port diversity of shark species within the port including bronze whalers, activities of breakwater wall construction and dredging could negatively hammerheads, various cat sharks, spotted raggedtooth and even white impact on the health of the marine environment. On the other hand the sharks. Many of the shark species recorded are highly sensitive to over- port had the potential of not only providing a sheltered environment, but exploitation and have been decimated in other parts of the world. Two of also a novel rocky reef habitat, which could potentially benefit local fish the most commonly encountered species were dusky sharks and populations. To try and answer these questions a catch and release smooth houndsharks which were encountered in their hundreds. tagging programme was initiated to better understand the fish Although dusky sharks can grow up to 4 m in length, all of the sharks that population within the port. This unique study is one of only a handful have been caught and tagged were less than a metre long. By tagging worldwide that has investigated the composition and abundance of fish and recapturing individual juvenile sharks we estimated that over 500 within a port both before and after it has become operational. We were dusky sharks utilise the port as a nursery area. This shark species in blown away by what we found! particular has a very slow growth rate, is late to mature, produces a small number of pups and has a long gestation period.As a result, concern has been raised regarding whether this species can absorb the high levels of fishing mortality it is currently subjected to in South Africa. The identification of an important nursery habitat and core activity zone within the port is therefore an important step in their management and conservation in SouthAfrica.

Aerial photos indicate that the port is home to hundreds of smooth houndsharks, which congregate in the shallows in the same months every year. Interestingly these sharks are almost all female and pregnant; however, we have never seen or caught a pup in the port. Whatever the reasons for their aggregation, it is evident that the port is functioning as an important habitat for this species. These, as well as other shark species may be attracted to the port not only by the abundance and diversity of fish species, but also by the relatively calm and sheltered environment the port creates in an otherwise high energy coastline.

During the initial stage of the project, which ran from September 2006 to September 2007 a total of 4 559 fish representing 47 different species were caught and released. Fish ranged in size from 5 cm long cape stumpnose (Rhabdosargus holubi) and puffer fish (Amblyrhynchotes honckenii) to 2.5 m raggedtooth sharks (Carcharias taurus). In addition to the commonly encountered species such as dusky kob (Argyrosomus japonicas), elf/shad (Pomatomus saltatrix) and garrick/leervis (Lichia amia) we also caught several unusual fish including sub-tropical species of kingfish as well as king (Scomberomorus commerson) and queen mackerel (Scomberomorus plurilineatus), which are rarely seen south of Port St Johns in the Eastern Cape. Although not caught, white sharks, whale sharks and even manta rays were regularly seen in the port. To put this into perspective, the abundance of fish was considerably greater than that recorded in any other estuary or shore location in South Africa. The port is essentially one of, if not the most productive fish environments in South Africa and is functioning as an important nursery Hundredsofsmoothhoundsharkscongregatingintheshallows area for many species of fish. withinthePortofNgqura

The giant guitarfish, or more commonly known as the giant sandshark, is Up until the end of 2013, 4 132 giant guitarfish had been tagged, of which the largest guitarfish species caught in South Africa (> 310 cm total 208 (5%) had been recaptured. The majority (96%) of all the tagging length and > 100 kg). It has a global distribution from the Red Sea and effort takes place in KZN during summer, with very few fish tagged tropical Indian Ocean south to the Eastern Cape, although it is most between April and October. Analysing the recaptures, the average common from KwaZulu-Natal (KZN) northwards. Due to the high quality distance moved by giant guitarfish was only 33 km. Furthermore, 80% flesh and large size of its fins, the giant guitarfish is one of the most (163 individuals) of the guitarfish recaptured moved less than 50 km prized and valued “shark” species in the Asian shark-fin soup trade and (Figure 3). Both these results suggest that there is minimal movement for this reason it is targeted throughout its distribution. It has shown between South Africa and Mozambique. Seasonally, 56 guitarfish (28%) significant declines in population numbers in some areas of its were recaptured in summer further south from where they were distribution range and is therefore considered vulnerable on the IUCN originally tagged. However, an additional 37 guitarfish (18%) were red list (http://www.iucnredlist.org). recaptured further north from their original tagging locality, which does not provide convincing evidence of a southward migration during Over the past decade there has been much concern expressed by shore summer. Furthermore, 33 guitarfish (16%) also moved south in winter, anglers over the declining numbers of giant guitarfish being caught which adds further doubt to the possible seasonal migration of this along the east coast of South Africa. Considering this and its global species. If we analyse the size and distance moved by guitarfish, both vulnerability, scientists from the Oceanographic Research Institute mature and sub-adult fish showed similar movement patterns (Figure 4). (ORI) and the KwaZulu-Natal Sharks Board (KZNSB) investigated the Furthermore, fish that were free for longer periods did not necessarily catch records of this species over the past 40 years. In SouthAfrica three move greater distances. Overall, it appears that giant guitarfish main fisheries catch this species. These include: the competitive undertake exploratory movements over wide areas in search of recreational shore fishery, where guitarfish are targeted due to their resources and they do not show a predictable seasonal migratory large size for points in competitions; the KZNSB, where guitarfish are pattern along the KZN coast. Although individuals are captured caught as a by-catch in the bather protection nets situated along the seasonally (i.e. more in summer), is it possible that during winter KZN coast; and the KZN Prawn Trawl Fishery, which catches guitarfish guitarfish move further offshore where they are not accessible to shore as a by-catch while trawling for prawns on the Thukela Banks offshore of anglers. However, this aspect needs further investigation, possibly by the Thukela River. using acoustic telemetry. Sizevsaveragedistancemoved(km) The results from analysis of the competitive shore fishery and KZNSB data were somewhat sobering. Since 2000, the competitive fishery has 200 caught on average less than 60 guitarfish per year (only 7 in 2011), 180 ♂ ♀ Maturity which is a considerable decrease compared to an average of 323 160 guitarfish caught per year prior to 2000. Similarly, since 2000 the KZNSB 140 120 has caught on average 37 guitarfish per year, compared to an average of 100 127 per year between 1982 and 2000. For the Prawn Trawl Fishery, only 80 15 individual guitarfish were recorded in 169 trawls on the Thukela 60 Banks between 1989 and 1991. It should also be noted that currently in 40 the competitive shore fishery all guitarfish are released after capture, Distancemoved(km) 20 while 72% and 80% of the guitarfish caught by the KZNSB and Prawn 0 Trawl Fishery are released alive after capture. The obvious question 800 1000 1200 1400 1600 1800 2000 2200 2400 2600 Sizeclass(mmtotallength) then is: “Why have we seen a decline in the numbers of guitarfish over the past decade if most of the fish have been released alive?” Figure3: Averagedistancesmovedbyrecapturedgiantguitarfish

One theory which has been proposed is that during winter when the Averagedistancemoved(km) water becomes cooler, giant guitarfish migrate up the KZN north coast into Mozambique waters where they are deliberately targeted by local 80% fisherman for their flesh and fins.

If giant guitarfish are not migrating northwards into Mozambique waters where they are being caught and killed for their fins, then again the hvh “ Figure1:Giantguitarfishcarcasesconfiscatedfromavessel question remains: What can explain the declining trends seen over the ” arrestedinMozambiquein2008(Photo:DAFF) past decade? There are a number of factors that need to be highlighted. Firstly and probably most importantly, prior to 2002 the competitive shore fishery required all members to bring fish caught during competitions to the scale where they were weighed. This would have certainly negatively affected the population of guitarfish off the east coast, especially considering the average number of guitarfish caught prior to 2000 (i.e. 312 per year) and the life history of this species. Not only is it slow growing (exceeding 15 years of age), it also matures late and has a low fecundity (±4 pups per litter). Furthermore, considering fghfgh these life history characteristics, if 30% of the guitarfish caught in the KZNSB bather-protection nets die each year, over a 35-year period (the first nets were introduced in the 1950s with accurate data collection only commencing in the late 1970s) the number of guitarfish killed would exceed 1 000. Although few giant guitarfish were recorded in the prawn Figure 2: A giant guitarfish caught on the KwaZulu-Natal north trawls off the Thukela Banks, this fishery started in the late 1970s and no coast that was missing its dorsal fin (Photo: Barry Tedder) information exists for the first 10 years of operation. Giant guitarfish, Page10 therefore, could have been caught in large numbers in the early stages you wanted to keep one!). The KZNSB has also replaced some of the of the prawn trawl fishery but were fished out before data collection nets along the KZN coast with drum lines which seldom catch giant began in 1988. This is particularly important since many other shark and guitarfish. The number of trawls on the Thukela Banks has also ray species that occupy the same habitat as giant guitarfish (e.g. decreased substantially due to poor prawn catches, related to the honeycomb and sharpnose stingrays) use these banks as a nursery closure of the St Lucia Estuary, and the introduction of a 6-month closed area. Lastly, there is very little information on the survivability of released fishing season when by-catch is highest. Considering these changes, it guitarfish. The fact that the recapture rate is only 5% highlights this point. is likely that we should see an increase in the number of giant guitarfish Overall, the vulnerable life history characteristics of this fish coupled with caught along the coast in the future. However, we need to keep its continued capture in various fisheries, whether as a by-catch or target monitoring the catches of this species and possibly conduct an urgent species, has contributed to the overall decline in population numbers of stock assessment to assess the status of the populations off southern giant guitarfish along the east coast of South Africa. In addition, Africa. Furthermore, since its flesh and fins are highly sought after, evidence suggests that shark finning in southern Mozambique and urgent harvest and trade management is needed such as curtailment of possibly illegally in SouthAfrica has added to this demise. commercial exploitation throughout its range.

Simon Walker has been passionate about fishing since his early days and pursues all aspects of the sport. Early in 1986 he applied for a tagging kit from ORI and on 09 March 1986 he inserted his first tag into a galjoen at Waenhuiskrans near Bredarsdorp in the Western Cape. During 1986 he tagged 52 fish with three of them being recaptured within the year. His initial success sparked a long active participation in ORI's Tagging Project. I am sure many who have read a Tagging Newsletter Congratulations! would have seen his name amongst our top taggers. Up until 31 December 2013, Simon had privately tagged 4 820 fish. Every single one of these being a teleost, i.e. an edible fish with no sharks tagged at all. In fact, 95% (4 593) of Simon's tags are galjoen, which means he has only tagged 227 “other” fish, such as leeries and spotted grunter.

Due to his early success, on 13 October 1987, Simon was invited to participate in the Department of Environmental Affairs (DEA) De Hoop Marine Reserve long-term monitoring project. Now 28 years later, Simon is still actively tagging for ORI for his private fishing as well as still being an active member of the De Hoop fish tagging team. On the De Hoop project Simon has tagged 5 664 fish, of which he has recaptured 357, and has also caught 1 798 extra fish that were not tagged (like blacktail, lesser guitarfish/sandsharks, shysharks, etc.). This means that in total Simon Walker has surpassed the 10 000 fish tagged milestone with 10 484 fish tagged to date. This is undoubtedly one of, if not the T most fish tagged by any recreational angler in South Africa since the his certificate is awarded to inception of the tagging project.

In his private capacity, Simon tags the majority of the fish he catches in the Cape Point area. The quality and accuracy with which Simon has kept records of every fish he has ever tagged has been so good that it SIMON WALKER was deemed good enough to be used for research purposes. His tagging effort has also led to the inception of a low key tagging project in the Table Bay National Park. This is the most westerly research tagging data collected in South Africa and has been used in several scientific publications monitoring the influences of marine protected areas off for the tag & release of southernAfrica.

Simon Walker is a great example of an angler who has turned his passion of angling into something that benefits everyone and is a true citizen scientist. We would like to thank Simon for his ongoing support 10428 FISH and we would like to congratulate him on his 10 000 fish tagged. His efforts have certainly had a positive impact on improving angler awareness and knowledge about our linefish resources. The concept of tag and release has partly been responsible for changing the ethics of the recreational fishing community, many of whom now release their catch, thereby contributing to a more sustainable fishing future. We hope his story will inspire many other anglers in South Africa to adopt a more conservation conscious approach to their fishing pursuits including releasing some of their fish.
