# Disease-resistant fish reduce viral spread in aquaculture: study

A study from the Hebrew University's Faculty of Agriculture led by Prof. Lior David has illuminated the dual benefits of breeding disease-resistant fish in aquaculture. Focusing on common carp, the research demonstrated that fish resistant to cyprinid herpes virus type 3 have lower viral loads and higher survival rates than their susceptible counterparts. Crucially, these resistant fish also act as less effective vectors for disease, leading to decreased viral levels in the water and reduced transmission rates among tank inhabitants. Published in Scientific Reports, the study underscores the importance of genetic resistance in aquaculture fish populations, not only for improving survival but also for controlling disease spread, thereby enhancing overall aquaculture productivity and sustainability.
