Community-based resource management approaches adopted in the three tributaries of River Surma, North-East Bangladesh

Freshwater fishery resources are declining in Bangladesh due to over exploitation, anthropogenic causes and inadequate management. To improve sustainability of these resources, a community-based resource management initiative was implemented by Bangladesh's Local Government and Engineering Department. Working in partnership with community-based resource management the communities implemented a variety of management interventions. The purpose of this study is to assess the impact of community-based management on fisheries production and biodiversity.

Tracking nutrient flows in a multi-enterprise farming systems with a mass-balance model (ECOPATH)

Whether grown for sale or for on-farm consumption, vegetables and other crops are often managed as stand-alone, monoculture enterprises. Integrated farming can help improve the nutrient output-input balance sheet and efficiency, not only for each component, but for the whole farm agroecosystem. Quantitative methods that can assist farmers and researchers improve diversified and integrated natural resources management systems are emerging from the agricultural and ecological sciences.

Development of Diversity Arrays Technology markers as a tool for rapid genomic assessment in Nile tilapia, Oreochromis niloticus

The development of genomic markers is described for Nile tilapia, Oreochromis niloticus, using the Diversity Arrays Technology (DArT) genotype-by-sequencing platform. A total of 13 215 single nucleotide polymorphism (SNP) markers and 12 490 silicoDArT (dominant) markers were identified from broodstock of two selective breeding programs [Genetically Improved Farmed Tilapia (GIFT) strain from Malaysia and the Abbassa strain from Egypt]. Over 10 000 SNPs were polymorphic in either strain, and 2985 and 3087 showed strain-specific polymorphisms for the GIFT and Abbassa strains respectively.

Five principles for network success in Solomon Islands

In Solomon Islands, networks consisting of multiple partners are gaining momentum because of their potential to improve the capacity of communities, nongovernmental organizations (NGOs) and government stakeholders to achieve their goals. Many organizations see the value of creating, leading and being a part of networks, and there are some examples of where these investments have led to bigger or more widespread outcomes than organizations could have achieved on their own.
