Red Hybrid Tilapia, Oreochromis sp. is one of the famous consumed fish for people
around the world. However, many cases have been reported due to high mortality and
huge losses in tilapia fish farming caused by Tilapia Lake Virus (TiLV). No mortality
cases related with Oreochromis sp. and TiLV has been recorded in Malaysia, but has
been prevailing in other countries. The aim of this study was to detect the presence
or absence of TiLV in Red Hybrid Tilapia, Oreochromis sp. from Merbok, Kedah and
Karak, Pahang. The PCR analysis was conducted according to the method by Dong et
al., (2017). The samples taken show the clinical signs of Tilapia Lake Virus such as
haemorrhages, reddish body, skin lesions, erosions, open wound, ulcers, bulging and
