Feasibility of Cage Culture on Lake Malawi, Part 1: Physical, Chemical and Biological Processes
Type: Journal Article
The feasibility of cage culture in Malawi was fully evaluated using standard procedures involving a sub-model of dissolved oxygen and phosphorus budget models to compute carrying capacities in relation to bathymetric ...
Reorientation of aquaculture production systems can reduce environmental impacts and improve nutrition security in Bangladesh
Type: Journal Article
Aquatic foods are a critical source of human nutrition in many developing countries. As a result, declines in wild-caught fish landings threaten nutritionally vulnerable populations. Aquaculture presents an opportunity to ...
Wastewater treatment for land-based aquaculture: improvements and value-adding alternatives in model systems from Australia
Type: Journal Article
Settlement ponds are used to remove particulate and dissolved nutrients in Australian land-based aquaculture wastewater. At best, marine and brackish water settlement ponds reduce total suspended solids by 60%, but their ...
Developing aquaculture of Small Native Species (SNS) in Bangladesh: village level agroecological change and the availability of SNS
Type: Journal Article
Small native species (SNS) of fish are important source of protein and income for rural people in Bangladesh. A rapid rural appraisal study was carried out to explore the recent changes in the availability of SNS in relation ...
Low cost murrel seed production technique for fish farmers
Type: Journal Article
A simple and low-cost breeding technology for breeding the striped murrel, Channa striatus in hapas in ponds was developed in India.
Towards the maximum profitability of smallholder catfish nurseries: predator defense and feeding-adapted stocking of Clarias gariepinus
Type: Journal Article
To determine how best smallholders could maximize the profitability of their catfish hatcheries, the cost/benefit analyses of using fences, hapas and bird nets to exclude predators; as well as over-stocking to create food ...
Village-based farming of the giant clam, Tridacna gigas (L.), for the aquarium market: initial trials in Solomon Islands

Two-year surveillance of tilapia lake virus (TiLV) reveals its wide circulation in tilapia farms and hatcheries from multiple districts of Bangladesh
Type: Journal Article
Tilapia lake virus (TiLV) is an emerging pathogen in aquaculture, reportedly affecting farmed tilapia in 16 countries across multiple continents. Following an early warning in 2017 that TiLV might be widespread, we executed ...
Evaluating mortality using length-frequency data when growth parameters are poorly known
Type: Journal Article
A method is presented through which the total mortality undergone by several fish stocks of the same species can be compared when growth parameters are poorly known or unknown. Whereas the estimate of Z obtained via the ...
