Data collection for poverty assessments in Africa is time consuming, expensive and can be subject to numerous constraints. In this paper we present a procedure to collect data from poor households involved in small-scale ...
Estimates of strain additive and non-additive genetic effects for growth traits in a diallel cross of three strains of giant freshwater prawn (Macrobrachium rosenbergii) in Vietnam
Type: Journal Article
Additive genetic, heterotic and strain reciprocal effects were estimated using a diallel cross of two local wild strains of the giant freshwater prawn (Macrobrachium rosenbergii) in Vietnam (Dong Nai and Mekong) and a third ...
Quantitative genetic parameter estimates for body and carcass traits in a cultured stock of giant freshwater prawn (Macrobrachium rosenbergii) selected for harvest weight in Vietnam
Type: Journal Article
Benefits derived from selective breeding have been demonstrated in livestock and in some fish species, but by contrast, there have been few systematic selection programs reported for shrimps. Improving growth rate has been ...
Intersectorality in the governance of inland fisheries
Type: Journal Article
One of the defining characteristics of inland fisheries is that they are closely impacted by other essential human activities that rely on the same fresh or brackish water ecosystems, such as hydroelectricity generation ...
Can water productivity metrics guide allocation of freshwater to inland fisheries?
Type: Journal Article
Water productivity (WP) metrics have proven useful in comparing production efficiency of various crops. Recently, it has also been proposed to facilitate more equitable allocation of scarce freshwater resources between ...

Snake prices and crocodile appetites: aquatic wildlife supply and demand on Tonle Sap Lake, Cambodia
Type: Journal Article
Commercial trade is a major driver of over-exploitation of wild species, but the pattern of demand and how it responds to changes in supply is poorly understood. Here we explore the markets for snakes from Tonle Sap Lake ...
The natural history and fisheries ecology of Lake Chilwa, southern Malawi
Type: Journal Article
Lake Chilwa produces between zero and 24,000 metric tons of fish per year, making it one of the most productive but variable lakes in Africa. The size of the lake varies seasonally and among years, sometimes drying completely. ...
