Radio Transmitters

From 1979 to 1982,188 chinook salmon (Oncorhynchus tshawytscha) were tagged with radio transmitters to locate spawning areas in the glacial Kenai River, southcentral Alaska. Results confirmed that an early run entered the river in May and June and spawned in tributaries, and a late run entered the river from late June through August and spawned in the main stem. Spawning peaked during August in tributaries influenced by lakes, but during July in other tributaries. Lakes may have increased fall and winter temperatures of downstream waters, enabling successful reproduction for later spawning fish within these tributaries. This hypothesis assumes that hatching and emergence can be completed in a shorter time in lake-influenced waters. The time of upstream migration and spawning (mid- to late August) of the late run is unique among chinook stocks in Cook Inlet. This behavior may have developed only because two large lakes (Kenai and Skilak) directly influence the main-stem Kenai River. If run timing is genetically controlled, and if the various components of the two runs are isolated stocks that have adapted to predictable stream temperatures, there are implications for stock transplantation programs and for any activities of man that alter stream temperatures.

Salminus Brasiliensis

ABSTRACT We investigated whether the movement and distribution of the migratory fish, Salminus brasiliensis, were affected by a small reservoir. We also examined how movement and distribution were related to water temperature, flow, and rainfall. In December 2011 and January 2012, 24 individuals were captured downstream from the dam, tagged with radio transmitters and released in the reservoir (5.46 km² total area). After being released in the reservoir, 18 of the 24 tagged fish travelled upstream, taking an average of 16.6 days to leave the reservoir, with daily movements varying from < 5 km/day to > 24 km/day. However, only seven tagged specimens (29.16%) returned to the lower reservoir section, while the rest remained in the intermediate and upper reservoir sections. Longitudinal distributions and movements were positively related to both upstream flow into the reservoir and water temperature. We found evidence that S. brasiliensis can recognize the longitudinal gradient and is able to continue its upstream migration. On the other hand, the reservoir negatively affected downstream movements, possibly because disorientation prevented movement to the lower reservoir section. Based on these results, we suggest that the impact of small reservoirs on migratory fish species should be objectively addressed in environmental impact assessments and management programs.

Daily Distance

Adult lampreys, Geotria australis, began to enter Pigeon Bay Stream just before 7 August 1992. Lampreys moved upstream more or less en masse, because adults were found immediately above the tidal limit in August but at the mouths of headwater streams in late October. Capture rates of adult lampreys in fyke-nets were irregular and appeared to reflect the movement of the fish through stream sections as upstream migration occurred. The daily distance travelled by lampreys individually equipped with radio transmitters declined from a high of 87.8 m to 0 m between August and November. Lampreys typically selected the spaces formed under boulders, usually 25 cm in diameter, at the bottom of riffles and at the upstream ends of pools. With only one exception, lampreys were never seen above the surface of the substratum. Movement occurred only at night and at the onset of freshes. Even though upstream movement had ceased for some two to four weeks, lampreys had not spawned and gonads remained far from mature by 30 November 1992.
