Larval kelp (Sebastes atrovirens), brown (S. auriculatus), and blackand-yellow (S. chrysomelas) rockfish were reared from known adults, to preflexion stage, nine days after birth for S. chrysomelas, to late postflexion stage for S. atrovirens, and to pelagic juvenile stage for S. auriculatus. Larval S. atrovirens and S. chrysomelas were about 4.6 mm body length (BL) and S. auriculatus about 5.2 mm BL at birth. Both S. atrovirens and S. auriculatus underwent notochord flexion at about 6–9 mm BL. Sebastes atrovirens transform to the pelagic juvenile stage at about 14–16 mm BL and S. auriculatus transformed at ca. 25 mm BL. Early larvae of all three species were characterized by melanistic pigment dorsally on the head, on the gut, on most of the ventral margin of the tail, and in a long series on the dorsal margin of the tail. Larval S. atrovirens and S. auriculatus developed a posterior bar on the tail during the flexion or postflexion stage. In S. atrovirens xanthic pigment resembled the melanistic pattern throughout larval development. Larval S. auriculatus lacked xanthophores except on the head until late preflexion stage, when a pattern much like the melanophore pattern gradually developed. Larval S. chrysomelas had extensive xanthic pigmentation dorsally, but none ventrally, in preflexion stage. All members of the Sebastes subgenus Pteropodus (S. atrovirens, S. auriculatus, S. carnatus, S. caurinus, S. chrysomelas, S. dalli, S. maliger, S. nebulosus, S. rastrelliger) are morphologically similar and all share the basic melanistic pigment pattern described here. Although the three species reared in this study can be distinguished on the basis of xanthic pigmentation, it seems unlikely that it will be possible to reliably identify field-collected larvae to species using traditional morphological and melanistic pigmentation characters.

John Cronyn (1827-1898) emigrated to Canada from Ireland in 1837. He studied medicine at the University of Toronto, but was not granted his degree upon completion of the requirements. He refused to take the test oaths meant to exclude Catholics from the profession and was not granted his degree until several years later, when the discriminatory laws were rescinded. In 1850, he married Elizabeth Willoughby of Toronto. They settled in Fort Erie and he established a successful medical practice there. He was active in the community, serving as Superintendent of schools and one term as Reeve. In 1859 he relocated to Buffalo and continued to practice medicine there. Cronyn was instrumental in the establishment of a medical department at Niagara University, where he was a professor and president of faculty. Nelson Forsyth was the son of William Forsyth (1771-1841), a prominent businessman in Niagara who owned and operated the Pavilion Hotel (later known as Forsyth’s Inn). Nelson was also a businessman and lived in Fort Erie with his wife Archange Warren.
