Bangladesh is rich in aquatic resources with extensive seasonal and perennial water bodies throughout the country. In the past, the expansive floodplains, oxbow lakes, beels, and haors were home to a vast range of fish species. Of the 260 fishes found in the inland waters of Bangladesh, 150 grow to a small size (maximum length of about 25 cm), and these are found in the wetlands.
Scientists should ensure that high quality research information is readily available on the Internet so society is not dependant on less authoritative sources. Many scientific projects and initiatives publish information on species and biodiversity on the World Wide Web without users needing to pay for it. However, these resources often stagnate when project funding expired. Based on a large pool of experiences worldwide, this article discusses what measures will help such data resources develop beyond the project lifetime.
Leadership is heralded as being critical to addressing the “crisis of governance” facing the Earth's natural systems. While political, economic, and corporate discourses of leadership have been widely and critically interrogated, narratives of environmental leadership remain relatively neglected in the academic literature. The aims of this paper are twofold. First, to highlight the centrality and importance of environmental science's construction and mobilization of leadership discourse.
The purposes of this paper were to firstly assess trends in North Sea pH data and to determine whether there is any long-term relationship between the pH data and the abundance of calcifying plankton.
Increased production of mola and other small fish can be achieved through stock enhancement and sustainable management of natural wetlands. Enhanced fish production can increase consumption and provide nutritional benefits, especially for women and young children, as they suffer from high rates of malnutrition, including micronutrient deficiencies. Mola and other small fish, which are eaten whole, have high contents of vitamins and minerals. In recent years, there has been a reduction in fish production and biodiversity in wetland areas of Bangladesh.
This is the first record of the dusky grouper Epinephelus marginatus (Lowe, 1834) in the eastern English Channel. One specimen was caught on 10 June 2011 in the Bay of Seine. It measured 66 cm and weighed 5.5 kg. From the study of internal organs and scales, this specimen was a female of 12 years old that did not grow in the Channel, which confirms the fact of a stray specimen and not the sign of an extension of the distribution with an established population.
This guide was developed to document the process and activities that WorldFish staff have used and adapted as facilitators working with communities interested in marine resource management in Solomon Islands. It draws on the experiences from work conducted with FSPI and MFMR through ACIAR funded projects, with communities that had a primary interest in the management of coral reef fisheries. Since 2011 the process has been trialed and adapted further with communities interested in mangrove ecosystem management (through the MESCAL project).
A trophic model of Lake George, Uganda, Central Africa was constructed using published quantitative and qualitative information on the various biotic components of the lake and the ECOPATH II approach and software. It is shown that the available production and biomass estimates for the various groups in the system are consistent with each other, and that it is possible to make a balanced model of the major trophic interactions in Lake George.
Social networks play an important role in facilitating effective and sustained connections between people responsible for regional conservation plans and those responsible for local conservation actions. Yet, few studies have utilized social network analysis in systematic conservation planning initiatives; this, in spite of social network analysis being developed as a structural and relational approach to describe and analyze the characteristics of patterns of relationships that make collaborative efforts more or less effective at solving natural resource management problems.
The Barotse floodplain is an ecosystem characterized by a paradox of widespread poverty amidst high ecological and agricultural potential. The CGIAR Research Program on Aquatic Agricultural Systems (AAS) seeks to address this paradox on the assumption that the rural poor have the potential to transform their lives using the aquatic resources in their environment. Understanding the conditions for natural resources use and management is critical for a program that seeks to transform the livelihoods of households dependent on natural resources.
