Relationships between climate, growth and fisheries production in a commercially exploited marine fish
… variability can affect fish populations and fisheries production in numerous ways, including inducing measurable fluctuations in fish growth, condition, and fisheries production. Unfortunately, mechanisms driving these linkages are poorly understood for most exploited species, which hinders …

Floodplain Resource Management: An Economic Analysis of *Policy Issues in Bangladesh
… the tradeoffs between floodplain agriculture and fisheries production in the Brahmaputra river basin of Bangladesh, where both sectors are simultaneously affected by floodplain development policies. Our goal is to study the impact of development policies on these two sectors and to identify key …

Ecosystem Services of Restored Oyster Reefs in a Chesapeake Bay Tributary: Abundance and Foraging of Estuarine Fishes
Oyster reef restoration may enhance the production of ecologically or economically important fish species, an ecosystem service, by providing refuge and foraging habitat. Predicting the effects of oyster habitat restoration on fisheries production in Chesapeake Bay requires a better understanding …

Valuation of Global Inland Fisheries Catch to Food Security
… are threatened with extinction. Inland capture fisheries contribute to food and nutritional security, livelihoods and help address the United Nations Sustainable Development Goals. Inland fisheries make a significant economic contribution nationally and globally, with an estimated value of USD …

Addressing the land loss-fish production paradox
… of marsh edge and area of intertidal marsh) to fisheries production, but for most species, landings and survey data showed differing patterns of abundance through time. These findings emphasize the importance of using survey data (not landings data) to conduct habitat-related analyses in …

Restoring and valuing global kelp forest ecosystems
… that ecosystem. Chapter 5 quantifies the fisheries production, nutrient cycling, and carbon sequestration potential of five key genera of globally distributed kelp forests. I conclude the thesis by reviewing the lessons learned and the steps required to advance the field kelp forest …

Análise da estrutura genética populacional da piraúna (cephalopholis fulva: serranidae) ao longo da costa e ilhas oceânicas brasileiras
… background shows a growth of marine fishery production until 1985 and within this period it was recorded a steady decline. From the year 2003 fishing statistics aim to some "recovery" of the total fisheries production, which probably is related to a change in industry practice. The target of …

Mangroves, fisheries and community livelihoods
… fishing communities through the enhancement of fisheries production. Ongoing loss of mangrove extent globally is therefore of societal concern given that communities living near mangroves rely on mangrove-fishing for income and subsistence. Whilst research and conservation efforts have …

Trophic dynamics in Australian seagrass beds : unravelling linkages from nutrients to fish
… (e.g. nutrient enrichment) and top-down (e.g. fisheries exploitation) processes. To enhance understanding of bottom up and top-down influences in productive estuaries, this study investigated a prominent four level food chain (epiphytic algae, mesograzers, juvenile fish, and piscivorous fish) …
