Abstract
Halibut (Hippoglossus hippoglossus) larvae were raised from hatching
to beyond metamorphosis in 11.5 m3
plastic bags with a temperature stable around 6掳C. Standard length, myotome height, eye diameter and
yolk sac length were measured on live or freshly preserved material.
Mouth development and functionality, pectoral and pelvic fin
development, intestinal development and the initiation of peristaltic
contractions, and eye pigmentation and migration were observed from
live material. The gape of the jaws was limited by an oral membrane
which appeared coincident with the developing mouth and which
persisted in either full or remnant form up to around the time of
first feeding. The phenomena of yolk sac vesicles and the Non-reducing
Yolk Sac Syndrome are discussed
