“…Sea surface temperatures during spring and summer within regions that juvenile Pacific salmon migrate can be useful predictors in models of survival rates or recruitment of Pacific salmon (Friedland, 1998; Mueter et al , 2002). Sea temperature is an important variable regulating Pacific salmon consumption and growth rates (Donaldson & Foster, 1940) and in regulating growth and production of their potential prey ( i.e . zooplankton; Corkett & McLaren, 1978; Huntley & Lopez, 1992).…”

Interannual variations in distribution, size, indices of feeding and condition of juvenile Bristol Bay sockeye salmon Oncorhynchus nerka collected in August to September (2000–2003) during Bering–Aleutian Salmon International Surveys were examined to test possible mechanisms influencing their early marine growth and survival. Juvenile sockeye salmon were mainly distributed within the southern region of the eastern Bering Sea, south of 57°0′ N during 2000 and 2001 and farther offshore, south of 58°0′ N during 2002 and 2003. In general, juvenile sockeye salmon were significantly larger (P < 0·05) and had significantly higher indices of condition (P < 0·05) during 2002 and 2003 than during 2000 and 2001. The feeding index was generally higher for age 1.0 year sockeye salmon than age 2.0 year during all years. Among‐year comparisons suggested that Pacific sand lance Ammodytes hexapterus were important components of the juvenile sockeye salmon diet during 2000 and 2001 (20 to 50% of the mean wet mass) and age 0 year walleye pollock Theragra chalcogramma were important components during 2002 and 2003 (50 to 60% of the mean wet mass). Warmer sea temperatures during spring and summer of 2002 and 2003 probably increased productivity on the eastern Bering Sea shelf, enhancing juvenile sockeye salmon growth.

The physical effect of logging on salmon streams : a summary report covering a 5-year calilbration period on four streams in Southeast Alaska /

The principal and most valuable industry of Alaska has been the salmon fisheries. Future development of Southeast Alaska, however, will depend on an increasing utilization of its important forest resource. The fisheries resource and the timber resource are intimately related. Reliable answers are therefore needed as to whether large-scale pulptimber logging is harmful to the spawning facilities of salmon streams. The Alaska Forest Research Center began a program of research in 1949 to relate logging practices by Forest Service standards to changes in the large-scale physical factors of the stream environment. ±' The study is divided into two parts: (1) collection of quantitative information on type and extent of physical change which takes place in these streams prior to logging, and (2) quantitative change following logging. Four streams, located in the Kasaan Bay area, Prince of Wales Island, were selected for long-term study. Two of the study watersheds will be logged; two will not be logged. Measurements are being made of such factors as climate, streamflow, storms and associated runoff, base flow, water temperature, stream channel change, sedimentation, and others. Rate and characteristics of streamflow influence both the physical and the biotic elements of the stream. This phase of the study will determine the effect of timber harvest on stream runoff. Basic data collected include a continuous record of stream height, discharge velocity associated with stream height, snow and ice conditions, analysis of storm flow, and groundwater depletion. Data are presented showing mean monthly stream height, mean monthly discharge, the relationship between rainfall and runoff, analysis of flood peaks, ratio of maximum to minimum stream discharge, and groundwater depletion.

The chief objective of this study was to analyse the effects of altered water temperature, due to the hydropower regulation of the River Alta, on growth of Atlantic salmon parr. The river was developed for hydroelectric purposes in 1987. A 110 m high concrete dam was built in the main river 49 km upstream from the outlet to the sea. The outlet of the power station is located 2.5 km downstream from the dam. The annual regime of water temperature has been altered downstream from the power station because of the regulation. It has decreased 1-2°C during June, July and the first half of August, while it has increased up to 3°C during late summer. During winter, water temperature has increased from 0°C to about 0.3-0.4°C. Atlantic salmon is the predominant fish species in the river. They can penetrate 46 km from the sea, up to the outlet of the power station.In this paper I have studied the relationship between growth of juvenile Atlantic salmon and water temperature in the upper part of the river. At similar temperatures, the growth rate of salmon parr in the River Alta is higher in early summer than later in the growing season. In early summer the salmon grew faster than the maximum rate predicted by a recently published model. Therefore, I adjusted the model to describe growth rates of salmon in early summer (ice break to mid-August), using data derived prior to the hydropower development (1981)(1982)(1983)(1984)(1985)(1986)).The new model proved effective at describing growth rates of fish in early summer following the hydropower development (1987)(1988)(1989)(1990)(1991)(1992)(1993)(1994)(1995)(1996). After development, growth rates decreased during early summer, but increased correspondingly later in the season. There was close agreement between these growth changes and the altered annual regime of river temperature. Overall, only minor changes in annual growth rates have been observed after the hydropower development.
