The New Zealand brill, Colistium guntheri, is an edible flatfish of the family Pleuronectidae. It is a demersal fish native to shallow seas around New Zealand, at depths of between 27m (89feet) and 49m (161feet). It can grow to 91cm (36inches) in length and can weigh up to 1.8kg (04lb).[1] [2]
The New Zealand brill is a righteyed flounder and so has both its eyes on the right-hand side of its body. Its upper surface is dark grey in colour, with its edges and fins almost black; the outer edge of each scale is black, which explains the longitudinal black lines that occur along the length of the body.
