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.

Fish to 2050 in the ASEAN region

The Association of Southeast Asian Nations (ASEAN) has emerged as a global fish producer, owing to the rapid growth of aquaculture in Southeast Asia and its large offshore fishing fleet. Fish is a regional commodity that is traded globally, and this region is at the frontline of the global trend toward meeting seafood demand by 2050. Fisheries and aquaculture are increasingly becoming a primary source of protein and micronutrients, foreign exchange, livelihoods and well-being for the population in the region.

Uncovering human social networks in coping with Lake Chilwa recessions in Malawi

This paper provides an in-depth understanding of social dynamics in the form of kinship ties in matrilineal societies. It unpacks gender roles and relationships at the community level to understand how social structures, created by the pattern of relations, enhance or hinder coping initiatives during lake recessions in the Lake Chilwa socio-ecological system.

Informal artisanal fish trade in West Africa: Improving cross-border trade

In West Africa, fishing and trading in fish and fishery products has been practiced for centuries and makes a significant contribution to per capita GDP. This policy brief illustrates fish trade flows in West Africa, and includes estimates of volumes, values, key traded fish species, the main value chain actors and challenges being experienced by these actors. It also recommends options that should be considered for policy formulation and implementation by national and regional policy makers.
