Thesis (MSc)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: The aim of this study was to determine the scale of marine poaching in the Table Mountain National Park by analysing the amounts of South African abalone, West Coast rock lobster, and shellfish, finfish and bait species confiscated from fishers operating in the park’s marine protected area between 2000 and 2009. The research objectives were fourfold, namely to strengthen conceptual frameworks on illegal harvesting in protected areas; identify the quantities of the various species seized by park officials over the decadal period; cartographically plot the areas in which confiscations took place; and distinguish the different resource users and stakeholders operating in the park and examine the roles they play in resource exploitation. Data was collected from offence logbooks maintained by SANParks rangers and managers, and from records kept by Marine and Coastal Management and the South African Police Services. GIS outputs indicated seizure events over the spatial area of the park. Further data relating to the levels of poaching was sourced from illegal fishers operating in the park who discussed their operations candidly. The research findings indicate that poaching of both abalone and rock lobsters has increased significantly over time. Other marine species show lesser amounts of resources poached over the ten-year period. Spatial outcomes suggest that confiscations of abalone occur predominantly on the east coast of the park, while higher seizure events occur on the west coast for lobsters. Shellfish, finfish and bait species were confiscated in equal amounts from illegal fishers on both the east and west coasts. Future research recommended includes garnering further confiscations data from the police services and undertaking contemporary baseline assessments to discover the effects poaching has had on the resource base since the previous stock assessment in 2001. The challenge laid out for the custodians of the Table Mountain National Park marine protected area is to provide and protect cultural and environmental resources, without compromising biodiversity management, community associations and conservation strategies. / AFRIKAANSE OPSOMMING: Die doel van hierdie studie was om die skaal van marienebronstroping in die Tafelberg Nasionale Park te bepaal deur middel van die ontleding van die hoeveelhede Suid-Afrikaanse perlemoen, Weskus-kreef en skulpvis, vinvis en aasspesies wat vanaf oortreders (2000 tot 2009), gekonfiskeer is. Die doel van die navorsing was viervoudig naamlik, die versterking van die navorser se konseptuele-basis rondom die stroping van hulpbronne in beskermde gebiede; die bepaling van die hoeveelhede en tipe spesies wat deur parkbeamptes in beslag geneem is; die plekke waar konfiskasies plaasgevind het; en om die verskillende hulpbron gebruikers en belanghebbendes te onderskei en hulle rolle in die mariene-hulpbron benutting te ondersoek. Primêre konfiskasie-data is verkry vanaf SANparke se logboeke wat deur beamptes instandgehou is en sekondêre data is verskaf deur Mariene en Kusbestuur en die Suid-Afrikaanse Polisiediens. Beslagleggingsgebeure is dmv GIS tegnologie op kaarte vasgelê. Verdere inligting oor die vlakke van stroping is bekom deur openhartige gesprekvoering met vissers wat onwettig in die park bedrywig is. Die navorsing het bevind dat die stropery van perlemoen en kreef met die verloop van tyd aansienlik toegeneem het. Ander mariene spesies het kleiner hoeveelhede stropery van die hulpbron oor die studietydperk aangetoon. Ruimtelike voorstellings toon dat perlemoen-stropery hoofsaaklik aan die ooskus van die park voorkom, terwyl groter beslagleggings/konfiskerings van kreef aan die weskus van die park plaasgevind het. Skulpvis, vinvis en aasspesies is gekonfiskeer by vissers wat onwettig bedrywig is in ewe groot hoeveelhede op beide die ooskus en die weskus. Toekomstige navorsing moet meer inligting oor beslagleggings van die polisie bekom en die kontemporêre basislynassesserings moet meer gereeld onderneem word om veral die effek van stropery op die hulpbron bloot te lê. Die laaste basislyn-assessering het in 2001 plaasgevind. Die uitdaging voor die bewaarders van die park se marienebeskermde gebiede is om kulturele en omgewingshulpbronne toeganklik vir alle gebruikers te maak maar dit ter selfder tyd ook te beskerm, sonder om biodiversiteit, gemeenskapassosiasies en bewaring strategieë te kompromitteer.

Tourism fuels the Zanzibari economy but adds to the depletion of marine resources. However, the concept of corporate biosphere stewardship suggests that companies with consolidated power can influence sustainability pathways. Can tourist hotels practically support octopus closures, a novel conservation tool, as a way towards sustainable marine resource consumption? I address this issue by making the first known attempt to estimate Zanzibari hotels’ seasonal and annual octopus demand, mapping their value chain structure and identifying the nature of their demand. The study relies on semi-structured interviews of 31 respondents (hotel staff, hotel suppliers, market traders, food importers and key informants) and official data. I assess the demand of hotels to range between 16 to 27 percent of the mean 2008-2018 annual catch in Zanzibar. Hence, this consumer power hotels may confer agency for them to contribute to resource conservation such as octopus closures. Hotels may support closures particularly if they match seasonality in octopus price and demand. However, hoteliers’ use of a wide sourcing network including imports may lead to diluted price signals hampering understanding and incentives to protect the local octopus supply. Additionally, hoteliers’ weight preferences largely correspond with the Zanzibari voluntary minimum weight limit, but do not align with the desired outcome of bigger octopus from closures. The typical practise of purchasing fresh octopus and limited freezer capacity of hotels may also limit their agency to support octopus closures. This study makes a novel contribution of linking octopus conservation with tourism. It furthermore nuances the concept of corporate biosphere stewardship by assessing the practical potential of Zanzibari tourism, a less consolidated industry, to contribute to marine resource conservation.  Further research into local biosphere stewardship of value chains within low-income country contexts should investigate differences in use of consumer power by small as opposed to large-scale businesses. In addition, similar assessments could benefit from research into local spatial and relational value chains, and their influence on hoteliers’ capacity to perceive of supply status through price signals, not only for octopus but seafood in general. / Utalii unakuza uchumi wa zanzibar lakini umekubwa na kupungua kwa rasilimali za bahari. Ingawaje, dhana ya uhirika wa kibailogio stewardship umependekeza kua nguvu ya mashirikiano ya makampuni yanaweza kuchangia njia endelevu. Inawezekana kwa mahoteli ya kitalii yakatoa msaada wa vitendo wa kufungia pweza wasivuliwe kwa kipindi maalumu, kama zana ya uhifadhi wa mazingira ambayo ni njia ya kupelekea matumizi endelevu ya matumizi ya rasilimali ya bahari? Ninaangalia suala hili kwa kufanya majaribio ya kwanza kwa kukadiria mahitaji ya pweza kwa hoteli za Zanzibar kwa msimu na kwa kila mwaka, kuyaainisha maeneo ya mnyororo wa thamani na kutambua maumbile ya upungufu wake. Utafiti huu ulikuwa ni wa muundo wa mahojiano ya wazi na watu 31 walihojiwa (wafanyakazi wa hoteli, wasambazaji wa mahoteli, wauzaji wa masokoni, wasafirihaji na watu wengine wanohusika) na taarifa za takwimu. Nilipima mahitaji ya mahoteli kwa asilimia kati ya 16 mpaka 27 ya jumla 2008-2018 upatikanaji wa kila mwaka kwa zanzibar. Hivyo basi nguvu ya maoteli wanaweza kua mashirika ya kuchangia uhifadhi wa rasilimali kama kufungia mwamba kwa uvuvi wa pweza. Mahoteli yanaweza kuwasaidia kufungwa kwa mwamba kwa uvuvi wa pweza hasahasa ikiwa watafanana kwa msimu na kwa upatikanaji. Ingawaje wenye mahoteli wanatafuta chanzo kikubwa ikiwemo kuagiza kutoka nje ambayo inaweza kushusha bei na ni ishara ya kuzuia kutoa motisha ya kulinda usambazaji wa ndani. Kwakuengezea wenye mahoteli uzito wanaoupendelea unawiana na ule wa kiwango cha chini cha Zanzibar, lakini hayaendani na matokeo ya matakwa yao ya pweza wakubwa wakati wa kufungia mwamba kwa uvuvi wa pweza. Mahoteli hayawezi kuwa kama mashirika ya kusaidia kufungs pweza kutokana na kutaka pweza ambao wametoka kuvuliwa na vilevile uwezo mdogo wa majokofu yao kuweza kuhifadhi pweza hao. Utafiti huu utaleta mchango mpya baina ya uhifandhi wa pweza na utalii. Na vilevile itaelezea dhana ya mashirikiano ya kibiosphere stewardship kwa kuchunguza umuhimu halisi wa utalii wa Zanzibar, muunganiko mdogo wa wadau katika kuchangia uhifadhi wa rasilimali za bahari. Tafiti zijazo zinazohusiana na biosphere stewardship ya mtiririko wa thamani kwa muktadha wa nchi zenye kipato kidogo zifanye uchunguzi juu ya tofauti ya nguvu ya watumiaji wadogo wadogo inavyoenda kinyume na biashara kubwa. Kwa kuengezea uchunguzi kama huo utanufaisha watu wa hali za chini na mahusiano ya mnyororo wa thamani na mchango wao kwa uwezo wa wenye mahoteli kutambua hali ya usambazaji kupitia bei zake si kwa pweza peke tu bali ni kwa vyakula vya baharini vyote.
