Fish Farms Contribute to Rising Sea Levels Many of the issues with aquaculture, or fish farming, are well documented. Farmed fish compete for space against wild fish, and they carry new parasites and diseases. They contribute to water pollution and often eat wild fish, further depleting overfished populations.

The U.S. Is Farming More Fish than Ever (But Nowhere Near What China Does) Unlike China, America has yet to take the bait on fish farming. In a report out last week, the National Oceanic and Atmospheric Administration (N.O.A.A.) reported a total catch of 9.2 billion pounds of seafood for American ports, beating averages for the last 10 years.

Numbers from N.O.A.A. make one fact abundantly clear: When it comes to aquaculture, the U.S. remains a tiny fish in an growing Asian pond.

"Scholars of common property resource theory (CPR) have long asserted that certain kinds of institutional arrangements based on collective action result in successful environmental stewardship, but feedback and the direct link between social and ecological systems remains poorly understood. This paper investigates how common property institutional arrangements contribute to sustainable mangrove fisheries in coastal Ecuador, focusing on the fishery for the mangrove cockle (Anadara tuberculosa and A. similis), a bivalve mollusk harvested from the roots of mangrove trees and of particular social, economic, and cultural importance for the communities that depend on it. Specifically, this study examines the emergence of new civil society institutions within the historical context of extensive mangrove deforestation for the expansion of shrimp farming, policy changes in the late 1990s that recognized "ancestral" rights of local communities to mangrove resources, and how custodias, community-managed mangrove concessions, affect the cockle fishery. Findings from interviews with shell collectors and analysis of catch-per-unit-effort (CPUE) indicate that mangrove concessions as common property regimes promote community empowerment, local autonomy over resources, mangrove conservation and recovery, higher cockle catch shares, and larger shell sizes, but the benefits are not evenly distributed. Associations without custodias and independent cockle collectors feel further marginalized by the loss of gathering grounds, potentially deflecting problems of overexploitation to "open-access" areas, in which mangrove fisheries are weakly managed by the State. Using Ostrom's Institutional Analysis and Development (IAD) framework, the explicit link between social and ecological systems is studied at different levels, examining the relationship between collective action and the environment through quantitative approaches at the fishery level and qualitative analysis at the level

Entre os TURFs tratados na Oficina TURFs & TERRITÓRIOS PESQUEIROS o Prof. Gonzalo Rodiriguez se deterá nos TURFs associados a aquiculutura, cuja atividade gera externalidades negativas intrasetoriasee intrersetoriais. No artigo de Becky Mansfield em anexo o foco é nas extenalidades intersetoriais e trata das implicações para a saude do consumidores dos produtos resultante do deslocamento da produção do ambiente natural para o ambiente artificial da aquicultura.

O ponto de partida do artigo é a constatação que "Privatization is often viewed to provide positive stimulus for the economy that can lead to the better-ment of society", o que se pode complementar, com a constatação de E Ostrom, segundo a qual, em algumas situações o regime privado se coloca como uma panancéia. Naste mesma linha, os autores chamam atenção que que qando " the appropriate governance systems are not functionally in place, the unwanted effects of privatization can have deleterious consequences." "This paper highlights the conse-quences of undesirable privatization and the emergent unwanted privatization tendencies of the coastal commons, particularly in the developing countries such as the Philippines. The lack of coherent policies,standards, and weak enforcement of policies in leasing the coastal commons (e.g. various unregulatedaqua culture) in the Philippines in particular, have resulted to alarming displacement, deprivation and marginalization of fishing and farming communities and have degraded many coastal zone areas. Os autores tratam do usos multiplos do solo, In addition, poorly planned coastal tourism and housing development projects in the foreshore areas,inappropriate reclamation of coastal areas, illegal usurpation of indigenous peoples rights over ancestral domain areas, and conversion of fishing and fish farming zones into ecotourism zones further aggravated this scenario. Equitable access to resources is of paramount importance to afford concerned stakeholders greater participation in terms of developing greater capacity for coastal communities to engage and demand for improved coastal governance e an important facet of public dministration often identifiedas one of the challenges in managing the commons. Co-management with an Ecosystem-Based Management approach as core operational mechanism provides opportunities to enhance policy formulation and implementation, secure community safety nets, and facilitate the crea

DECOMMISSIONING (offshore Installations), FISHERIES AND AQUACULTURE Decommissioning of offshore installations can cause problems both for the fisheries and for aquaculture industry, including fish farming, but of rather different kinds. For the fisheries, any problems are largely related to the offshore phase of decommissioning, and include restrictions on access to areas, the impacts of pollution (including noise), and interference with fishing activities if installations and pipelines are left in place. For aquaculture, potential problems are largely related to onshore activities, and include restricted access to areas and the impacts of pollution (including noise). Risks to the reputation of fish products on different markets could be a problem both for the fisheries and the aquaculture. Reputation is a sensitive factor, and easily influenced in a negative direction. Pollution incidents could have a major impact, especially at local level. Experience shows that it takes a long time to restore a good reputation. There are no special arrangements for compensating for this type of loss other than the normal compensation rules. This issue should therefore be taken into special consideration if permits are to be issued for areas where fisheries and aquaculture are important.
