<jats:title>Abstract</jats:title><jats:p>The aquaculture of marine finfish in Newfoundland presents a challenge due to the cold‐water (<0 C) conditions which occur over a four to five month period. As part of a continuing research program on the culturing of cold‐water marine finfish species we report on preliminary results of two “new” aquaculture species. The lumpfish and the Ocean pout both occur along the coast of Newfoundland and are adapted to a cold‐water environment. Lumpfish have been reared from egg masses collected from the wild or from eggs stripped in the hatchery. Eggs and larvae are relatively large and larvae are well developed at hatch. Larvae will feed on day‐old <jats:italic>Artemia</jats:italic> nauplii after four to six days. Survival over the first eight weeks is high but declines over the first year. Lumpfish cultured in the laboratory become sexually mature and produce eggs (roe) at the end of their second year. Ocean pout have been cultured only from egg masses collected from the wild. Eggs and larvae are extremely large compared to other marine finfish currently being cultured. Larvae hatch during the cold‐water period, absorb the yolk‐sac within 24 hours and are ossified at hatch. Juveniles feed on <jats:italic>Artemia</jats:italic> nauplii within two days at very low temperatures. Survival is comparatively high (75–80%) over the first year. Initial results are encouraging but more research is required before commercial production of these species would be feasible.</jats:p>
