Embryological development is followed over a period of ten weeks after hatching. The mode of formation of the components of the vertebral column is compared with that in Clupea harengus, and is described in detail where differences are observed or additional information is available. Development appears essentially similar in the two species, although in general more rapid relative to length in C. pallasii. At hatching, myotome formation is complete and the ultimate vertebral number of an individual is presumably determined by that time. During ossification of the vertebral column, complex growth gradients from one or more centres are observed.

The food of the Pacific herring Clupea pallasii consists during the larval stage principally of ova of various kinds with circular diatoms. No food was found in fish less than 9 mm. in length. Postlarvae and fry take the greatest variety of food, Copepoda and Cirripedia larvae being the most important items. Apparently the most readily available of suitable foods is taken. Adults confine themselves to a crustacean diet (except herring ova occasionally), Copepoda and Euphausiacea comprising the bulk of the food, Calanus predominating in the spring and Euphausia during the remainder of the year. Purse seined herring rarely contained any food. Copepoda are on the whole the most important food of the Pacific herring.

Climate change has been identified as a major influence on basin water balances. However, land use and water use practices have also been identified as players. This case study was completed to better understand a changing water balance affecting a major basin in Alberta. The Beaver River basin is located in east central Alberta. Much of the basin has been developed for agricultural use; however, a number of heavy oil operations also exist. Both sectors use surface and groundwater. Evidence exists that the basin hydrology has changed since the mid-1970s. Coincidently, it was at this time that much of the land was cleared for agricultural development and commercial-scale oil development began. Oil industry use of water was suspected as the main cause for the changes observed. To investigate this further, data from regional hydrometric and meteorological stations were assessed along with water well hydrographs and historical satellite images. A significant correlation was found between basin responses and a climate phenomenon known as the Pacific decadal oscillation. Although the correlation between the Pacific decadal oscillation and basin hydrology appeared strong, deforestation for agricultural development also seemed to have an effect. Use of the local water resources was found to be of minor significance.
