This technical report documents the pathogen screening of 29 genetically improved rohu, catla, and silver carp samples collected through the CGIP program and tested at the Khulna University–WorldFish joint laboratory. Using standardized PCR and RT-PCR protocols, the aquatic animal health team assessed the presence of five high-priority pathogens—EUS, SVCV, KHV, TiLV, and CEV—with all pooled samples testing negative. The findings confirm the disease-free status of the broodstock and backup fingerlings at the time of testing, supporting safe dissemination of improved carp seed and strengthening upstream biosecurity within aquaculture production systems.
