Murkray Livers are acquired by cutting up Murkray caught through Fishing. Go to Fisher Hai-Luk in Cetus, select the desired amount of Murkray available, and select the "Cut Fish" option to extract the components. Each Murkray cut yields one Murkray Liver.
Asides from being crafting materials, Tenno needs to sacrifice 5 Murkray Livers, along with credits, standing, and other resources, to rank up from Trusted to Surah with the Ostron.
