Species Gadopsis marmoratus Richardson, 1848

River Blackfish, Blackfish, Freshwater Blackfish, Marble Cod, Marbled River Cod, Slimy, Slippery, Tasmanian Blackfish

Introduction

Genetic studies have suggested that there is a northern and southern population that probably represent separate species (Miller et al. 2004). Kuiter (2013) split the southern population into two additional species, Gadopsis gracilis McCoy 1879 in the southeast of Victoria, and an undescribed species in the southwest. Further work is required to determine the validity of these species. Genetic studies (Hammer et al 2014, Unmack, et al. 2017) have suggested that additional species exist within the genus and the present classification is tentative.
