Early Life History of Pacific Herring: Relationships of Larval Dispersal and Mortality to Environmental Conditions. Final Report of Port Moller Planning Study

摘要

A review of the scientific literature on the transport of pelagic fish eggs and larvae by oceanic and estuarine transport systems shows that a strong link is believed to exist between transport and survival of young fish, particularly for Pacific herring, Clupea harengus larvae. The report recommends that the Generalized Longitudinal, Lateral and Vertical Hydrodynamic and Transport (GLLVHT) be used for studies on the population dynamics of herring larvae in Port Moller, Alaska. The structure of the model is briefly summarized. Water pressure sensors should be placed at the western entrance to Port Moller and near Bear River. A current meter may be required near Frank's Lagoon. Temperature and salinity should be measured along the boundaries of the system as well as at each plankton station. A meteorological station should be established near the entrance to Port Moller, and flow rates of at least two of the major tributaries draining into Port Moller should be measured. Series of horizontal tows at different depths should be taken at some of the deeper stations, whenever it is logically possible.
