“…Because the holding time occurred when each fish crossed to the next step in the fish passage, this finding indicated that the holding time occurred before or after the burst speed over U crit . During upstream migration, chum salmon had a consistent holding behavior after swimming at high speed over U crit , indicating that they swim at speeds greater than U crit prior to holding (Makiguchi et al 2007). Chum salmon showed a higher number of trials than masu salmon at each fish passage, indicating that chum salmon swim over U crit .…”

“…External attachment is suitable for shortterm telemetry research, which reduces handling stress for the fish (Bridger and Booth 2003;Makiguchi et al 2007). To attach the tag, experimental fish were anaesthetized using FA100 (eugenol; Tanabe Seiyaku Co. Ltd, Osaka, Japan) at a concentration of 0.5 m·L −1 in water from the Chitose River and placed upright on a surgical table.…”

Abstract:The spawning ground of chum salmon (Oncorhynchus keta) is usually 31 located farther downriver than that of masu salmon (O. masou) in Hokkaido, Japan. To 32 compare the swimming abilities of these two species, the relationship between 33 swimming speed and oxygen consumption was compared using a swim tunnel in the 34 laboratory. Then, the upstream-migration behaviors of chum and masu salmon were 35 compared using electromyogram (EMG) telemetry at fish passages in the Toyohira 36 River, Hokkaido. In the laboratory study, the standard metabolic rate of masu salmon 37 was lower and the critical swimming speed (Ucrit) was faster than those of chum salmon. 38In the field study, the holding time needed to recover the swimming performance 39 exceeding Ucrit at the fish passages, and the trial number needed to pass the fish 40 passages were significantly lower for masu salmon than chum salmon. These results 41revealed that masu salmon are more adaptable to extended swimming in 42 high-water-velocity conditions than chum salmon and that masu salmon are better 43 equipped for a long distance upstream to their spawning ground than chum salmon.

“…The voltage corresponding to muscle activity was sampled from the beginning to the end of the experiment every 3 s. The mean value from the samples was calculated, assigned an activity level (EMG signal) ranging from 0 to 50 (no units) and transmitted to a radio receiver (model SRX_600; Lotek Engineering Inc.). Following an hour of recovery, the EMG signals from the fish tagged with EMG transmitters were converted to swimming velocity following the method of Makiguchi et al (2007Makiguchi et al ( , 2008b) who used the same swim chamber for a respirometry experiment. Water from the Shibetsu River was pumped into the chamber before each trial.…”

Do secondary sexual traits, such as large dorsal hump and hooked snout, decrease the swimming efficiency of male pink salmon during freshwater migration? This is the first study to address the effects of secondary sexual traits in pink salmon on oxygen uptake and swimming capacity. We conducted a laboratory experiment using a swimming respirometer and a field study using electromyogram (EMG) telemetry in the Shibetsu River, Hokkaido, Japan. We compared the relationship between MO2 (mg O2·kg−1·h−1) and swimming velocity U (m·s−1) in male and female fish, and also investigated the effects of morphological traits (secondary sexual characters) on the relationship between MO2 (mg O2·kg−1·h−1) and swimming velocity U (m·s−1). Additionally, we compared energy costs and swimming behaviour during upstream migration between male and female pink salmon. The laboratory experiment revealed that MO2 exponentially increased with increasing U; this increase was described by MO2 = 167.9e1.23U for males and 144.9e1.14U for females. Linear mixed models found that hump height and the upper jaw length in males significantly and positively affected the relationship between MO2 and U; no effect was found in females. The field study found that swimming velocity for both sexes estimated from EMG calibration was lower than optimal swimming velocity (Uopt) calculated from the laboratory experiment. We suggest that pink salmon in the Shibetsu River do not swim at the optimal swimming velocity because of the short migration distance involved (20 km).

“…electromyogram [EMG], accelerometer, tail beat) (Cooke et al 2004;Cooke et al 2008). Tags with EMG transmitters have been widely used outside of Australia, for example in the recent research undertaken in Canada and Japan on salmon (Ueda 2004;Makiguchi et al 2007;Cooke et al 2008;Makiguchi et al 2008). These studies have found that swimming speeds, swimming pattern, and energy use of migrating fishes vary with environmental and biological factors.…”

Abstract. Diadromous fishes are a frequent but poorly understood component of coastal riverine fish communities in Australia. There are ,33 diadromous fishes found in Australian waters, mainly catadromous and amphidromous species. An extensive review of the literature identified major information gaps about the lifecycles and ecology of many of these species, with information on facultative diadromy, navigation, marine and early life stages being particularly limited. In many cases, this lack of information has led to poor management decisions and consequently many of the Australian diadromous species are under increasing threat from a range of environmental impacts. Much of the required information is difficult to obtain with traditional field surveys and, as a result, new and improved research tools and technologies, including telemetry, otolith chemistry, stable-isotope analysis (SIA) and functional magnetic resonance imaging (fMRI) are increasingly being applied. Key areas for research on Australian diadromous fishes should involve: (1) use of telemetry and otolith chemistry to determine the level of facultative diadromy and variation in diadromous movements across a species range; (2) use of otolith chemistry and SIA to gain a greater understanding of larval and juvenile marine life stages of catadromous and amphidromous species; and (3) use of fMRI or traditional techniques such as electroolfactogram (EOG) to determine the role of olfaction in spawning and migration, and the impact of impoundments and agricultural run-off on these critical life history stages.
