“…This electrode was designed to replace previous designs based on stainless steel plates or rods (Spoor et al, 1971;Morgan, 1977;Miller et al, 1980;Cairns & Garton, 1982;Borch et al, 1993). The main disadvantage of stainless steel is the erratic variation in the quality of the signal due to electrolytical processes occurring on the electrodes associated with the potential differences between the electrodes, even if these are small.…”

Resting heart rates and ventilation rates in rainbow trout Oncorhynchus mykiss at 15 C are 31·8 1·8 beat min 1 and 53·1 3·7 breaths min 1 , respectively. The non-invasive recording system picked up the bioelectric potentials generated by the fish in the water and was based on an array of six silver-silver chloride electrodes covered with agar-gel, which provided a better signal-to-noise ratio than in previously described systems, and allowed the determination of heart rate and ventilation rates at different swimming speeds up to 2 l s 1 . In concert with the lower rates, the scope for changes in heart rate and ventilation rate during swimming was also considerably larger than in earlier studies (2·4-and 2·0-fold, respectively). Two main conclusions result from this work: (i) short recovery times under 48 h after anaesthesia and surgery are unlikely to provide truly resting heart rates and ventilation rates in trout at 15 C; (ii) heart rate regulation during exercise is more important than previously thought and might account for a larger proportion of the increase in cardiac output observed in swimming trout. 2000 The Fisheries Society of the British Isles

“…Significant differences in yawns were observed only between the control and low, low and medium, and low and high concentrations ( Table 3). Coughs have been associated with clearing gill surfaces of particulate matter or mucus that forms in response to an irritant [28], and yawns seem to be a more extreme effort to do the same. Miller [27] suggested that yawning can also be indicative of stress.…”

The behavioral effects of three sublethal concentrations of methyl parathion on social groups of bluegill (kpomis macrochirus) were examined. Consistently similar hierarchies were formed in all test groups, allowing for comparison both before and after toxicant administration. Significant increases in comfort movements and respiratory disruptions and decreases in aggressive behaviors were observed after methyl parathion was added to treatment tanks. Changes in the frequencies of the affected behaviors occurred primarily within the first 24 h of the treatment period. In every treatment, the most subordinate and dominant individuals were affected more pronouncedly than were intermediately ranked fish. Consequently, differential, contaminantinduced responses associated with rank should be considered when conducting bioassays and perhaps ultimately examined in the field when dealing with species which form social hierarchies. Examination of this factor could help clarify the relative roles of social stress and toxicant stress in producing an effect.

“…This is probably why ventilation frequency has hardly been used to estimate metabolic activity but has mainly been used as a n indicator of stress (e.g. Cairns & Garton 1982, McCloskey & Oris 1991, Szyper & Lutnesky 1991, Baldwin et al 1994, Laitinen & Valtonen 1994, Zimmerman & Watters 1994). Oswald (1978) recorded electromyograms from red fibres in a muscle involved in closing the mouth, and found relatively low (near resting level) and constant ventilation rates (maximum increase 52 to 56 % over lowest rate) for brown trout in their natural habitat.…”

ABSTRr\CT: Spontaneous fluctuations in oxygen consumption (R) and ventilation frequency (VF) of stoplight parrotfish Sparisoma virjde were measured simultaneously in small flow-through respirometers to establish the relationship between these variables. Respiration of l l fish of varying size (14 to 1052 g) and life phase (juveniles, initial and terminal phasc adults) was measured at naturally fluctuating temperatures A large proportion of the variance In respiration could be explained by the equation: R = 0.00035 X V F ' 3b% W ' '!"r2 = 93.1 n = 380, p < 0 001), with R in mg O2 h-', V F in beats min-l and flsh weight ( W ) in g . Oxygen concentration in the respiration chambers could drop below natural levels Cornpanson of the R-VF relationships at different concentrations showed that correction for [02] hardly affected the predictions. No important differences were found between the 3 life phases, and inter-individual d~fferences were no larger than the variation between replicate measurements. We conclude that the equation above appears quite robust and can therefore b e used to predict the metabolic rate of undisturbed fish in their natural environment.
