he global shrimp farming industry has been affected by regular outbreaks of diseases, causing catastrophic crop failures with severe financial losses (Shinn et al., 2018b). Acute hepatopancreatic necrosis disease (AHPND), or Early Mortality Syndrome (EMS) as it is more commonly known, the microsporidian Enterocytozoon hepatopenaei (EHP) and white spot virus disease (WSD) are the top bacterial, parasitic and viral diseases respectively, impacting whiteleg shrimp Penaeus vannamei production (Phuoc et al., 2009; Lightner et al., 2012; Sajali et al., 2019). The collective losses attributed to AHPND alone throughout a number of Asian countries (i.e. China, Malaysia, Thailand,
