Grenadiers (Rattail * has about 50 species)
Most species small, averaging 15-30 cm, but a few grow to over 60 cm. Several genera and over 20 species in New Zealand waters. A commonly caught species, the javelin fish (Lepidorhynchus denticulatus) can be distinguished from most other grenadiers by its silvery body, and from hoki by its black ventral surface and blunt snout. Grenadiers or macrourids can be an important trawl by-catch and are generally captured in waters deeper than 200 m. The largest group of grenadier species are the rattails (Coelorinchus spp), abundant in 200-800 m, together with the javelin fish. They are potentially commercial, but macrourids are probably more important as food for other fish. Resource size (all species combined) unknown but possibly large, capable of an annual yield of 10,000-20,000 tonnes.
