Book excerpt: The identification of Atlantic herring stocks inhabiting both sides of the northern Atlantic has been the subject of numerous investigations for many years. In more recent years, the discreteness of the spring and autumn herring populations in the Gulf of St. Lawrence was established, a separation important for delineating proper fishery management units. Otolith characteristics, such as shape and first year's growth, were used in both the Gulf and Newfoundland regions, but the method used requires well-trained technicians and was criticized because of its subjectivity. A semi-automated microcomputer-based measuring system was developed for otolith measurements in the Gulf region to eliminate such subjectivity. The method uses a microscope with a drawing tube and a digitizer interfaced to a personal computer which analyzes the digitized otolith measurements using software packages. This report presents results using this system to separate herring spawning groups by otolith morphometrics.

Book excerpt: "Pacific herring, Clupea pallasi, is an important forage fish species, which interfaces with various trophic levels including human beings. There have been many herring studies about reproductive biology and migration dynamics, but not many studies about the underlying mechanisms. For fisheries management, reliable spawning prediction models are necessary. I sought to understand the mechanisms behind the variability in northern Bristol Bay herring spawning variability and migration dynamics in the eastern Bering Sea (EBS). Through a combination of spatio-temporal approaches and statistical methods, I found significant statistical relationships between herring spawning and spring environmental variables. All the best models include air-sea-ice interactions through their effects on gonad maturation and migration. EBS herring undergo a pseudo-clockwise seasonal migration with adjustments in response to changes in oceanographic conditions along the ice edge. Ocean temperature changes near the ice edge, which are controlled by atmospheric gradients over the North Pacific Ocean, explain most of the interannual variability of herring spawning in northern Bristol Bay"--Leaf iii.
