Risk factors and opportunities of intensive shrimp (Penaeus Monodon) production in Bangladesh

Shrimp aquaculture play an important role in Bangladesh economy. It provides livelihood of several hundred thousand small-scale shrimp farmers and about half a billion United States dollars export revenue each year. The production system in Bangladesh is mainly extensive and productivity is low compare to many Asian countries such as China, Thailand and Vietnam. In recent years, a trend has been observed towards intensive culture system to increase productivity of shrimp farms.

Identifying hotspots for antibiotic resistance emergence and selection, and elucidating pathways to human exposure: Application of a systems-thinking approach to aquaculture systems

Aquaculture systems are highly complex, dynamic and interconnected systems influenced by environmental, biological, cultural, socio-economic and human behavioural factors. Intensification of aquaculture production is likely to drive indiscriminate use of antibiotics to treat or prevent disease and increase productivity, often to compensate for management and husbandry deficiencies. Surveillance or monitoring of antibiotic usage (ABU) and antibiotic resistance (ABR) is often lacking or absent.

To cluster or not to cluster farmers? Influences on network interactions, risk perceptions, and adoption of aquaculture practices

Over the course of just a few years, shrimp farming has become a major aquaculture production system in coastal areas of several developing countries across the globe. However, farmers are facing a variety of risks related to disease, market, and climate, which influence risk management strategies and adoption of new technologies.

AMFORA: Applying a One Health systems modelling approach to formulate strategies for mitigating the risk to human health of ABR in aquaculture

Aquaculture systems are highly complex and influenced by environmental, biological, cultural, socio-economic and human behavioural factors. The growing importance of aquaculture is fuelling a transition of small-scale farming to industrial intensification in LMICs. Two interdisciplinary workshops were held in 2018, in Vietnam and Egypt. They aim to use a ‘systems-thinking’ approach to map aquaculture systems and identify potential hotspots for the emergence and selection of resistance and human exposure to antibiotics and antibiotic-resistant organisms.

Moving beyond the shrimp farm: Spaces of shared environmental risk?

Key environmental challenges faced by the aquaculture sector demonstrate that aquaculture production is not isolated from the surrounding environment, and we see a policy shift towards area-based approaches. However, without an understanding of the farmer's perspective, there is a danger of misrepresenting how farm-level practices relate to area-based approaches and to environmental risk management. This paper empirically examines how individual aquaculture farmers interpret and manage environmental risks and the extent to which they operate beyond the boundaries of their farms.

Including GHG emissions from mangrove forests LULUC in LCA: a case study on shrimp farming in the Mekong Delta, Vietnam

Mangrove forests have been recognized as important regulators of greenhouse gases (GHGs), yet the resulting land use and land-use change (LULUC) emissions have rarely been accounted for in life cycle assessment (LCA) studies. The present study therefore presents up-to-date estimates for GHG emissions from mangrove LULUC and applies them to a case study of shrimp farming in Vietnam.

Are shrimp farmers actual gamblers? An analysis of risk perception and risk management behaviors among shrimp farmers in the Mekong Delta

Shrimp farming is considered a “risky business” and often compared to gambling for farmers. It is associated with a diverse range of risks and uncertainties, including volatile markets, climate variability, and production risks. In order to mitigate the effects of unpredictability farmers may decide on a particular stocking density and adopt different risk management strategies.

Trophic model of the coastal fisheries ecosystem of the west coast of peninsular Malaysia

A preliminary mass-balance trophic model was constructed for the coastal fisheries ecosystem of the West Coast of Peninsular Malaysia (0 - 120 m depth). The ecosystem was partitioned into 15 trophic groups, and biomasses for selected groups were obtained from research (trawl) surveys conducted in the area in 1987 and 1991. Trophic interactions of the groups are presented. The network analysis indicates that fishing fleets for demersal fishes and prawns have a major direct or indirect impact on most high-trophic level groups in the ecosystem.

Status of demersal fishery resources in the Gulf of Thailand

Data from trawl surveys (1961 - 95) and annual production statistics (1971 - 95) were used to examine the status of demersal fishery resources in the Gulf of Thailand. Analyses were focused on biomass trends, population parameters and exploitation rates of dominant species, and assessment of excess capacity from fishing effort and yield estimates. The results indicate by 1995, the trawlable biomass in the Gulf had declined to only about 8.2% of the biomass level in 1961.
