Roundnose grenadier is slow growing, late to mature, long lived and has low reproductive capacity. They can therefore only sustain low levels of exploitation. They also exhibit aggreating behaviour which makes them vulnerable to exploitation. It is a deep-water species targeted by fisheries that are poorly regulated. It also occupies a habitat that is vulnerable to the impacts of trawling. Avoid eating.
Roundnose grenadier are a deep-water species found at depths from 180 to 2200 m. Large schools can be formed at 600 to 900 m. They are very slow growing and long-lived, maturing when 9 to 11 years old and reaching a maximum age of around 70 years and maximum size of 110 cm. Spawning occurs between July and October. Roundnose grenadier on the Mid-Atlantic Ridge exhibit aggregating behaviour and are associated with seamounts.
Roundnose grenadier is slow growing, late to mature, long lived and has low reproductive capacity. They can therefore only sustain low levels of exploitation. The state of stocks in these areas is unknown or there is insufficient information to determine reference points. Fisheries for this species should be accompanied by data collection programmes on target and by-catch fisheries, and scientific advice is that the fishery should not be allowed to expand, unless it can be shown that it is sustainable.

There are generally no directed fisheries for this species in these areas. It is taken as bottom trawl bycatch and in small amounts. Deep-water trawls impact the ocean floor, causing potential to deep-water coral communities. As this fishery is part of a mixed fisheries, effort on roundnose grenadier also impacts other commercial and non-commercial deep-water species.
