The intent of this thesis is to explore the role that social norms and values play in natural resource management systems and to see how communities may spread their social norms through ecological storytelling. The Maine lobster industry and Wabanaki communities in Maine are used as two examples for resource management systems. The Maine lobster fishery is known for being one of the most sustainable fisheries in the world. Their history is examined for how their environmental values and social norms influenced their behavior and what led to the establishment of their strong conservation ethic. Wabanaki groups in Maine are known for their traditional ecological knowledge and their use of storytelling to share environmental values. The groups are examined for their shared use of social norms in resource management and how their differing backgrounds and worldviews may influence those social norms and the effectiveness of them. The Maine lobster industry is found to have several key strengths and weaknesses—determining that ecological storytelling may serve as a method to enhance their community and avoid future conflict.

The condition at settlement of the western rock lobster pueruli presumably reflects both their energetic condition in reaching the near shore and subsequent recruitment into adult populations. In recruiting to the near shore the pueruli swim across the continental shelf where oceanographic conditions are complex and likely influence the success of recruitment. The results from the biochemical studies are interpreted in light of the oceanography off the coast of Western Australia. I investigated the nutritional condition of larval phyllosomata, post-larval puerulus and first instar post-pueruli juveniles of the spiny lobster, Panulirus cygnus, to determine energy use during the non-feeding transitional puerulus stage. Biochemical analyses of lipid, fatty acid (FA) and protein revealed that lipid, in particular phospholipids, is primarily used for energy during the nonfeeding puerulus stage. Monounsaturated FA showed the greatest decline with development, whereas the polyunsaturated FA showed a high degree of sparing, suggesting these FA are not used as a substrate for energy production. The knowledge gained on the biochemistry of energy use in P. cygnus was then used to investigate the spatial and temporal variability in the nutritional condition, in particular lipid condition, of puerulus collected at three near shore locations (Alkimos, Jurien Bay and Dongara) along the Western Australia coast, and one offshore location (Houtman Abrolhos Islands). The one offshore location was chosen as I hypothesised that arriving pueruli are likely to be in a better state of nutrition than those arriving at more coastal locations where the potential journey from offshore larval feeding grounds to the near shore is considerably greater. This element of my research showed lipid levels to be inversely related, generally, to shelf width but were variable, suggesting pueruli may travel complex trajectories to reach nearshore settlement. The lipid and FA composition of pueruli was also consistent with spatial and seasonal variation in Leeuwin Current and coastal productivity regimes.

This D.Sc. thesis presents a study about lobster fishing in the State of Ceará, Northeast region of Brazil, a traditional activity since the mid of the 1950 ́s, and represents an important fishing product of Brazil's exportation, driven by the lack of information on research, statistics, monitoring and evaluation. The history of the fishing in Ceará has shown minimal changes in the fleet, the types of vessels, the equipment and fishing methods, as well as in the species caught. There was a growing contingent of lobster fishermen and unemployment insurance as a social benefit. Some gaps were identified from design to application of the legislation involving lobster fisheries, since the identification of breeding areas protected, use the size of the meshes to the change on coefficient of the meshes. To optimize the process of commercialization and further analysis of Fisheries Biology, an international standardization was proposed for the classification of the entire lobster growth- related task to consistent weights and types. The various systems of existing databases and employed by various organs in the country were discussed. However, has not been verified the necessary integration to streamline monitoring and evaluation procedures, greatly hindering the process of management of public policies. The databases of fishing vessels present in the most diverse organs - Sisemb/DPC, MPA, SINE, MTE - should become single and with biometric reading by the boat owners, avoiding waste of time for both users, as for civil servants who feed and update information annually. In addition, recommendations or suggestions were presented to continuation and deepening of themes for the devel opment of future studies employed in productive chain management of lobster, and also to identify gaps and obstacles that hinder the implementation, monitoring and evaluation of development policy of lobster fishing by public agencies. The 21 undergraduate programs in Fishing Engineering existing in Brazil in 2013 and The Fishing Technology Colleges could contribute with their infrastructure, student body and teaching staff needed to achieve some goals of the MPA, as statistics and fishing extensions. / A formulação de políticas públicas para o ordenamento da pesca da lagosta é papel do Governo Federal, visando compatibilizar interesses diversos na cadeia produtiva da lagosta. Esta Tese de Doutorado apresenta um estudo sobre a pesca de lagostas no Estado do Ceará, Brasil, uma atividade tradicional desde meados dos anos de 1950, e que representa um importante produto pesqueiro de exportação do Brasil, motivado pela escassez de informações sobre pesquisa, estatística, monitoramento e avaliação. A situação histórica do setor pesqueiro cearense apresentou alterações mínimas na frota, nos tipos de embarcações, nos aparelhos e métodos de Pesca, assim como nas espécies capturadas. Houve um crescimento no contingente de pescadores de lagosta e do seguro-desemprego como benefício social. Foram identificadas algumas lacunas existentes desde a concepção à aplicação de parte da legislação que envolve a lagosta, seja na identificação de áreas de criadouros protegidas, no uso do tamanho das malhas e na alteração no coeficiente de entralhe das malhas. Para otimizar o processo de comercialização e posterior análise de biologia pesqueira, foi proposta uma padronização internacional para classificação da lagosta inteira relacionada ao crescimento coerente das gramaturas e dos tipos. Foram discutidos os vários sistemas de bancos de dados existentes e empregadas por diversos órgãos no país. No entanto, não foi verificada a integração necessária para agilizar os procedimentos de monitoramento e avaliação, dificultando sobremaneira o processo de gestão das políticas públicas. Os bancos de dados de embarcações pesqueiras presentes nos mais diversos órgãos - Sisemb/DPC, MPA, SINE, MTE - deveriam se tornar único e com leitura biométrica do proprietário da tripulação, evitando perda de tempo tanto para os usuários, quanto para funcionários públicos que alimentam e atualizam diversas informações anualmente. Além disso, recomendações ou sugestões foram apresentadas para a continuidade e o aprofundamento de temas para o desenvolvimento de futuros estudos empregados na gestão da cadeia produtiva da lagosta, ao identificar lacunas e óbices que impedem a implantação, o monitoramento e a avaliação da política de desenvolvimento da pesca de lagosta por órgãos públicos. Os 21 cursos de graduação em Engenharia de Pesca existentes no Brasil em 2013 e os tecnológicos em Pesca & Aquicultura poderiam contribuir com sua infraestrutura, corpo discente e docente necessários para atingir algumas metas do MPA, como estatística e extensões pesqueiras.

The series of experiments that comprises this thesis consider the use of prebiotics and probiotics to improve success in European lobster Homarus gammarus culture. Research was conducted at the National Lobster Hatchery and The University of Plymouth, UK between April 2007 and March 2010. Great potential was revealed for the application of biotics as dietary supplements in the culture of larval and juvenile H. gammarus. Specific biotics, namely; prebiotic mannon oligosaccharide (MOS) and probiotic Sanolife® (Bacillus spp.) were revealed to increase growth and survival during the culture of early lobster life stages. Lobsters that showed enhanced development and/or survival were found to possess improved feed conversion, immune status and/or stress tolerance. Furthermore it was found that biotic fed lobsters displayed shifts in gastrointestinal (GI) microbiology and enhanced physical GI structures, which may account for improved feed conversion and consequently growth. The work presented thus demonstrates that by making positive changes in GI structure and bacterial community composition combined with influencing immune status culture success can be positively enhanced through the biotic supplementation of diets. However, it must be considered that the outcome of dietary biotic supplementation is heavily influenced by the situation in question.
