Biosecurity Knowledge, Attitude and Practices in Cage Aquaculture: A Study of Fish Health and Disease Risk Management on Lake Kariba, Siavonga, Zambia

Le résumé fourni par la source

Cage aquaculture in Lake Kariba, Zambia, is critical to the region’s fish production but faces significant challenges in disease outbreaks. This study assessed the Knowledge, Attitudes, and Practices (KAP) of aquaculture producers in Siavonga concerning fish health and disease risk management. Data were collected through structured interviews with 14 producers, representing small, medium, and large-scale farms. The study aimed to identify gaps in biosecurity awareness and practices, particularly in relation to disease prevention and control.The results showed that knowledge of biosecurity and disease risks was predominantly low across all farm scales. Specifically, 90% of small-scale producers and 100% of medium-scale producers exhibited low knowledge, while 50% of large-scale producers showed low knowledge. Attitudes toward biosecurity were generally negative, with 90% of small-scale producers holding negative attitudes, compared to 50% of large-scale producers who demonstrated positive attitudes. The implementation of disease management practices was more consistent in medium- and large-scale operations, with 100% of large-scale farms following moderate to good practices, compared to 100% poor practices in small-scale farms.Significant gaps in adherence to best biosecurity practices were observed, particularly in small-scale farms. For instance, 60% of small-scale farms did not follow quarantine procedures, and only 20% assessed disease risks pre-movement. In contrast, 100% of large-scale farms implemented quarantine measures and assessed disease risks before moving fish.This study highlights the need for targeted interventions to improve biosecurity knowledge and practices, especially among small-scale producers, who constitute 71.4% of the respondents. Training, resource allocation, and policy enforcement are crucial to addressing these gaps and mitigating the risk of disease outbreaks that threaten the aquaculture sector’s sustainability in Lake Kariba.
