Este trabalho tem como objetivo analisar o modo de vida insular das ilhas Vitória e Monte de Trigo, no que ele possui de singular e em suas relações mais amplas com o continente. Parte-se da análise das questões pesqueira e de ocupação do espaço litorâneo, para em seguida verticalizar o estudo das comunidades de ilhéus monteiros e vitoreiros a partir de seu sistema de propriedade, das modalidades de uso dos recursos naturais e de seu modo de vida, que comporta a análise da divisão social do trabalho, da educação, da saúde, da religião e das relações que os ilhéus constróem com o continente. Foram identificados os problemas que interferem na reprodução do modo de vida insular e os mecanismos de subordinação da pequena produção pesqueira das ilhas ao mercado e ao capital industrial na pesca. As particularidades e singularidades destas comunidades foram apreendidas, comunidades que constróem sua identidade, seus espaços e territórios e seu não isolamento frente aos processos de apropriação dos recursos pesqueiros e de ocupação do espaço litorâneo e marítimo.

Both the use of and jurisdiction over fisheries resources is an important issue for many First Nations in British Columbia. Historically, fish played an important spiritual, social and economic role in numerous Aboriginal societies. These societies had various methods of managing the resource and, although they had the technological capacity to over-exploit the fisheries, they were able to maintain sustainable levels of fish. Following contact with European settlers, Aboriginal fishers were initially able to continue their traditional methods of fishing as well as expand their use of the fisheries through trade with non- Aboriginals. However, with the opening of the canneries on the coast the fisheries grew in economic importance to non-Aboriginal fishers and management of the resource was gradually but systematically taken over by the state, with various ideologies being used to justify the take-over. Aboriginal fishers lost not only their control over management of the resource, but also their ability to use it as extensively as they once had. Over the years, Aboriginal participation in both the food and commercial fisheries has declined although various government-sponsored programs have been initiated to attempt, with only partial success, to remedy this problem. In the meantime, the Department of Fisheries and Oceans has been battling other problems in the commercial fisheries, including over-capitalization of the fleet and depletion of fish stocks. Management of salmon in particular, because it is an anadromous species which travels through several different jurisdictions, has become extremely complex. It is in this context that much litigation over Aboriginal fishing has been launched. Only a few of the issues have been clarified by the judgments which have resulted and certain myths and ideologies have surfaced repeatedly in many of the decisions. It is likely that the recent decisions of the Supreme Court of Canada on Aboriginal commercial and management rights will result in increased complexity and political controversy. However, problems of fisheries management, including the accommodation of Aboriginal interests, is not unique to British Columbia or even Canada. Similar problems have been experienced elsewhere in the world and various types of co-management regimes have been established in various jurisdictions in an attempt to deal with some of these issues and to recognize a greater role for Aboriginal fishers and communities in fisheries management. It is not clear whether, and to what extent, comanagement will be adopted in British Columbia, or what the role of Aboriginal fishers might be in such a regime. Even if co-management is established, it is highly probable that the state's underlying regulatory regime will remain intact. However, co-management may result in increased Aboriginal participation in both the use and management of the resource. / Law, Peter A. Allard School of / Graduate

Diverse and abundant coral associated microbial communities may play a key role in coral resistance to and recovery from unwavering stressors currently threatening coral reefs worldwide. The composition and structure of the coral microbiome is integral to coral health as microbes can play beneficial (e.g. nutritional or protective) or negative (e.g. pathogenic or opportunistic) roles in the coral. To review the impacts of stressors on the coral microbiome, I compiled data from 39 studies, each tracking microbial community shifts in corals experiencing stress from climate change, pollution or overfishing. Stress was associated with shifts in coral microbial communities. I found that regardless of stressor, microbial alpha diversity increased under stress, with Vibrionales, Flavobacteriales and Rhodobacterales commonly found on stressed corals, and Oceanospirillales not as abundant on stressed corals. In addition, I used 16S rRNA sequencing to evaluate how local and global stressors affect the community structure of the coral microbiome for the two coral species, Porites lobata and Montipora foliosa. I monitored tagged coral colonies at two human disturbance levels (i.e. high and low), before and during a thermal bleaching hotspot at Kiritimati, Kiribati. Human disturbance, a bleaching hotspot, and coral species were all important drivers of coral microbiome community structure. My results suggest that human disturbance increases microbial alpha and beta diversity, although results vary between coral species, with P. lobata having more of a difference between disturbance levels. Similarly, bleaching increased beta diversity at low disturbance sites. Both human disturbance and thermal stress appeared to homogenize coral microbiomes between species and thermal stress appeared to homogenize communities between disturbance levels. Thus, both human disturbance and bleaching appear to stress the coral and destabilize its microbiome. However, intense thermal stress (i.e. 12.86 DHWs) appears to have a greater influence than human disturbance, probably due to corals responding to stressful conditions in a similar manner. In conclusion, my results highlight the impact of local and global stressors on coral microbiome community structure. / Graduate / 2018-04-26 / 0359

A large sportfishery that targets both smallmouth (Labeobarbus aeneus) and largemouth (Labeobarbus kimberleyensis) yellowfish exists in South Africa. Both species have high conservation priority, and no assessments documenting the effect of angling on L. aeneus and L. kimberleyensis have been undertaken. The overall aim of this study was to provide an assessment of the impact of angling on L. aeneus and L. kimberleyensis. The specific objectives of this study were to characterise the sectors utilising Lake Gariep, document catch, effort and total catch for the fishery as well as the locality specific biology of L. aeneus and L. kimberleyensis. The study was undertaken on Lake Gariep, South Africa's largest impoundment, situated on the Orange River system in central South Africa. Subsistence fishers were the dominant user group, constituting 60 % of the fishery, the remainder constituted recreational anglers. Angler catches were dominated by carp (Cyprinus carpio; 74 %), followed by mudfish (Labeo capensis; 13 %) and smallmouth yellowfish (8 %). Catches of largemouth yellowfish contributed < 0.5 % to the total catch. The relative abundance of species by weight differed by area (χ² test of independence: χ² = 182, df = 4, p ≤ 0.05). On any sampling day time fished was the best predictor for differences in probability of capture (PC) (Wald X²(1) = 7.169, p = 0.007). The probability of capturing L. aeneus differed significantly between month (Wald X²(5) = 20.690, p = 0.000) and region (Wald X²(3) = 46.755, p = 0.000). The single best predictor of differences in log abundance and non-zero CPUE was region (Factorial ANOVA p ≤ 0.05). Mean CPUE ranged from 0.21 ± 0.06 kg. man⁻¹.hr⁻¹ to 0.82 ± 0.11 kg. man⁻¹.hr⁻¹ in the OV region and 0.42 ± 0.10 kg. man⁻¹.hr⁻¹ to 1.17 ± 0.24 kg. man⁻¹.hr⁻¹ in the GD region. Angler effort was higher in OV than in GD and ranged from 17 ± 3 anglers/day to 45 ± 9 anglers/day and 6 ± 1 anglers/day to 41 ± 8 anglers/day, respectively. Total catch was higher in the GD 46.0 [95 % CI = 15:102.6] t. period⁻¹ than the OV region 40.0 [95 % CI = 13.9:89.6] t. period⁻¹. The total catch from the Lake Gariep fishery between March and December 2007 was estimated to be 86.0 [95 % CI = 40.4:154.8] t. period⁻¹. Age and growth was determined using whole otoliths. The growth of L. aeneus was best described by the von Bertalanffy growth model as Lt = 481.80 (1- e⁻°·²²⁽t⁺°·⁶¹⁾). Gonadal development for L. aeneus was seasonal, with the gonadosomatic index peaking in January, revealing a distinct spawning season. The length at 50 % maturity for female L. aeneus was attained at a fork length of 354.7 mm. Natural mortality (M) was estimated at 0.55 year⁻¹. The growth of L. kimberleyensis was described by the von Bertalanffy growth model as Lt = 763.22 (1- e⁻°·¹¹⁽t⁺°·⁶³⁾). Only 6 mature female and 15 mature male L. kimberleyensis were recorded during the study period. The smallest mature female was a 390 mm FL stage four female and the earliest recorded mature male was a 337 mm FL, ripe running male. Natural mortality (M) was estimated at 0.08 year⁻¹ for L. kimberleyensis. Per recruit analysis indicated that current fishing mortality reduces the L. aeneus spawner biomass by 7 %, which is considered negligible. Labeobarbus kimberleyensis forms an insignificant proportion of anglers catches and stock status is currently considered pristine.

A fishery-dependant monitoring method of the recreational shore-based fishery was undertaken in the Goukamma Marine Protected Area (MPA) on the south coast of South Africa for a period of 17 months. The method used was a roving creel survey (RCS), with dates, times and starting locations chosen by stratified random sampling. The MPA was divided into two sections, Buffalo Bay and Groenvlei, and all anglers encountered were interviewed. Catch and effort data were collected and catch per unit effort (CPUE) was calculated from this. The spatial distribution of anglers was also mapped. A generalized linear model (GLM) was fitted to the effort data to determine the effects of month and day type on the variability of effort in each section. Fitted values showed that effort was significantly higher on weekends than on week days, in both sections. A total average of 3662 anglers fishing 21 428 hours annually is estimated within the reserve with a mean trip length of 5.85 hours. Angler numbers were higher per unit coastline length in Buffalo Bay than Groenvlei, but fishing effort (angler hours) was higher in Groenvlei. Density distributions showed that anglers were clumped in easily accessible areas and that they favored rocky areas and mixed shores over sandy shores. Catch documented between October 2008 and December 2009 included a total of 361 fish, of 27 species from 12 families. Sparidae had the highest contribution (12 species). A Shannon-Weiner diversity index showed that diversity was higher in Buffalo Bay (0.81) than Groenvlei (0.57). Catch composition of retained fish (336 individuals) showed that the six numerically most important species were blacktail (Diplodus sargus capensis) (66 percent of catch), followed by galjoen (Dichistius capensis) at 11 percent, Cape stumpnose (Rhabdosargus holubi), belman (Umbrina robinsonii) and strepie at 3 percent, and elf (Pomatomus saltatrix) at 2 percent. Catch composition of an earlier study in Goukamma (Pradervand and Hiseman 2006) was compared with the present study, as well as data from the De Hoop MPA, which is closed to fishing. A multi-dimensional scaling plot of catch composition showed tight clustering of the De Hoop samples, and high variability among the Goukamma samples. A bray-curtis similarity index and dendrogram of similarity between study sites and study periods showed that there was an 83 percent similarity among De Hoop samples and a 75 percent similarity among Goukamma samples (ignoring the two outliers). The two sites are different with respect to species composition, but this is expected because they are different areas. Differences between time periods in Goukamma (i.e. the previous study versus the present study) were not significant. The most significant result from the catch composition analyses is the high variability among the Goukamma samples. This can be explained by the variable fishing methods used by anglers in Goukamma, compared with the standardized fishing methods used by researchers in De Hoop, and the fact that fish are more abundant and populations are more stable in De Hoop – giving higher sample sizes which reduce the variability in the statistics. Species-specific CPUE was calculated for the six numerically most important species. In both sections, CPUE was highest for blacktail, with an average of 0.133 fish per hour for Groenvlei, and 0.060 fish per hour for Buffalo Bay, over the 12 months. The second highest CPUE values per section were 0.030 for galjoen in Groenvlei and 0.039 for strepie in Buffalo Bay. Remaining CPUE values ranged from 0.014 (belman in Groenvlei) to the lowest value of 0.001 (strepie in Groenvlei). Total estimated CPUE for these six species in the MPA using the estimated effort and catch results amounted to 0.018 fish per hour. An annual estimated 3897 fish were landed in the reserve during 2009. Most fish (n=2481, 64 percent) were caught in the Groenvlei section. Numbers of blacktail were the highest of all species, within both sections (2353 fish). Strepie was the next most common (561 fish), but was caught almost entirely within the Buffalo Bay section (97 percent of individuals), followed by galjoen (548 fish) caught mostly within the Groenvlei section (92 percent of individuals). Size comparisons of the six species between the Goukamma and De Hoop MPAs showed that ranges in size are similar, but there are substantial differences in mean sizes between the two MPAs. Sample sizes of all species from the Goukamma MPA were too small to draw conclusions about stock status, except for blacktail. The Goukamma MPA is a popular fishing destination and angler effort is high. It can be considered a node of exploitation for surf zone fish, for which it provides no protection. Even though the MPA allows shore angling, sustainable fishing practices should be incorporated in management plans if the MPA is expected to protect and conserve its stocks. Of noteworthy concern is the occurrence of illegal night fishing (the public may not enter the reserve between sunrise and sunset) which leads to underestimates of catch and effort (night surveys were not conducted because of safety concerns). It is recommended that more communication should take place between the angling community and the reserve management. Sign boards giving information on species which are under pressure, and why they are under pressure, with a short explanation on their life cycles, is advised. The roving creel survey method was suitable for the study area and delivered statistically rigorous results. I thus recommend that it is continued in the future by management. I make some recommendations for reducing costs of future surveys, as well as for altering the survey design if funds are very limited.

This dissertation is an historical examination of policy and discourse as it impacts on ecological questions in South Africa, with a focus on land, mining and fishing. It shows how ecological issues are embedded in relations of class, race and gender. It argues that relation of nature and society and social relations form each other historically. Specifically, it makes visible how apparently progressive ideas to overcome the legacy of apartheid have served to perpetuate the ecological crisis after the end of apartheid. That is, although liberation ideology aims to overcome irrational and harmful forms of domination, current strategies of overcoming racial dispossession on the basis of capitalism rely on increasing and unbridled exploitation of natural resources. The dissertation concludes with a consideration of political perspectives and agency responding to the ecological crisis in South Africa today. It provides a survey of government, activist and community initiatives and assesses their capacity to help create a new relationship of nature and society, as the basis for a new society.

Thesis advisor: Carlo Rotella / This country currently finds itself in a backwards way. Since the late 1970s, our policy choices have led to a significant disparity between national economic productivity and individual workers’ pay. As GDP steadily grew between 1979 and 2020, wages remained largely stagnant and many Americans now find themselves incapable of keeping up with rising costs of living. Unlike most workers struggling in this precarious economy, college students graduating from elite universities are given the choice to embark on careers in financial and consulting sectors to achieve financial stability. That stability can only be achieved through only a handful of work-options, however, can feel restrictive to many college students, meaning this new America of limited opportunity is not felt exclusively by the working class and instead can be intuited at every class level. Over the course of one dissolute summer, I sought to better understand why many students, despite having the option to work lucrative jobs, feel pessimistic about working after graduation. / Thesis (BA) — Boston College, 2022. / Submitted to: Boston College.

Over the past four years both the media and academia have highlighted the labour conditions and human rights issues prevalent in Thailand’s offshore fishing industry. Even so, little has been written from the perspective of fish workers, and far less is known about fish work in the Southeast Asian region. This thesis contributes to these gaps by exploring the experiences of fish workers in several ports across Thailand and Vietnam, along with former migrant fish workers, to provide insight into labour conditions for fish workers and the risks associated with migration for fish work. To do so, the thesis draws upon four interview data sets involving 40 fish workers (including boat owners and captains) conducted in Thailand, Vietnam and Cambodia between 2014-2017, along with a review of the relevant literature on fish work, labour, and migration. After describing the experiences of fish workers in both countries, a number of themes emerge. These include challenges pertaining to recruitment, wages, risks at sea and agency. Each theme is unpacked in turn, to showcase the nuanced experiences of Cambodian fish workers in Thailand and internal migrants in Vietnam, but also to highlight how fish workers navigate complex migration processes. Specific to the Thai context, Derk’s (2010) early work on unfreedoms experienced by migrant Cambodian fish workers in coastal Thailand serves as a framework to compare and contrast working conditions between then and now. The thesis concludes with a reflection on migrant fish work and key areas that require further unpacking within the Southeast Asian context including what is happening in source countries (Cambodia, in this case, but also in other regions in Vietnam), while arguing that a modern slavery framing does not meaningfully protect migrant fish workers from unacceptable working conditions.

The purposes of this study were to gain a better understanding of anglers and angler preferences and to examine differences between subgroups of anglers based on level of specialization. Understanding these similarities and differences between user groups will provide valuable input for more effective fisheries management. A randomized mail survey was sent to resident, adult fishing-license holders in Utah. A 68% response rate yielded 1216 usable returns for data analysis. An analysis of three recreation specialization dimensions (participation, equipment and investment, and lifestyle) and further analysis of participation and investment variables were used to develop a typology of Utah anglers. Three specialization subgroups and four typology subgroups were then compared to determine differences in motivations for fishing, preferences toward various fishing and management attributes and the desirability of available fish species. Anglers with different levels of specialization differed significantly in their motivations for fishing, preferences for fishery resource attributes and desirability ratings of available fish species. Typology subgroups were found to not differ significantly in motivations, preferences or species desirability ratings. However, level of participation (number of fishing trips taken in past year) and investment (money invested in fishing equipment) were each valuable in identifying differences in motivations and preferences, but not in species desirability ratings. By identifying sportsmen constituencies based on specialization characteristics, managers can better provide fishing opportunities consistent with angler needs. Fisheries managers will have a tool to match sportsmen with the type of setting and management strategy desired or to match the management to the sportsmen, thus maximizing satisfaction.

Philosophiae Doctor - PhD / The achievement of sustainable development requires the balanced interaction between three components: the economy, environment, and society. Finding this balance in practice requires a critical examination of the beliefs, systems, and institutions that govern decisionmaking. Achieving sustainable development in reality thus involves understanding the existing forms of power in a particular time and place – what they are, how they operate, and how they influence decisions for development. This study is an analysis of power in a specific case study: the Hout Bay harbour in Cape Town, South Africa. Economic activities were driven by the fishing industry, in particular Oceana, who operated and maintained a fishmeal factory in the harbour since 1958. While the factory provided employment for the local coloured residents of Hangberg, it also produced noxious odours and air pollution, leading to significant discontent from other sectors of Hout Bay. A local and largely white activist group, Fresh Air for Hout Bay (FAHB), challenged these operations on the basis of sustainability and this became a highly contested issue. After years of debate and tension, the factory would eventually close in 2019, marking the end of an era for the fishing industry in Hout Bay. The purpose of this study is to analyse the power dynamics in Hout Bay and determine how these influenced the decisions around the factory. To do this, a qualitative autoethnographic study was conducted using semi-structured interviews, participant observation, and documentary review. The power analysis found that those in power, particularly the City of Cape Town and
