A long-lived marine fish (Hoplostethus atlanticus) of deep cold waters, especially off the coasts of New Zealand and Australia, having a bright reddish body and fished commercially for food.

An age-structured per recruit model was implemented, using life history and fishing selectivity parameters reported in DER (2012) (Table 1) to estimate [B.sub.msy]/[B.sub.0],[F.sub.msy]/M and [SPR.sub.msy] in the following demersal stocks managed by TAC in Chile: 1) Patagonian toothfish (Dissostichus eleginoides); 2) yellow-nose skate (Zearaja chilensis); 3) alfonsino (Beryx splendens); 4) orange roughy (Hoplostethus atlanticus); 5) cardinalfish (Epigonus crassicaudus); 6) Chilean hake (Merluccius gayi gayi); 7) southern blue whiting (Micromesistius australis); 8) pink cusk-eel (Genypterus blacodes), northern stock; 9) pink cusk-eel, southern stock; 10) southern hake (Merluccius australis), and 11) Patagonian grenadier (Macruronus magellanicus).

Unfortunately, the general longevity--some species such as orange roughy (Hoplostethus atlanticus) live up to 150 years--and slow maturation rates of many deepwater fishes make them highly susceptible to overfishing and slow to recover from an overfished state (Clark, 2001; Roberts, 2002; Clarke et al., 2003).
