“…The timing of the spring spawning is consistent with observations made during other smallmouth bass spawning studies in Nebish Lake (Baylis et al 1993) and in other northtemperate lakes such as Pallette Lake, Wisconsin (Gillooly andBaylis 1999, Saunders et al 2002), Lake Opeongo, Ontario (Ridgway et al 1991), and Two Island Lake, Ontario (Picard et al 1993) as well as in laboratory studies (Cantin and Bromage 1991).…”

We observed that the smallmouth bass (Micropterus dolomieu) population in Nebish Lake, Wisconsin spawned twice-once during the traditional spring period and then again in summer, well beyond the typical spawning season for north-temperate lakes. We documented this anomalous spawning behavior and compared the characteristics of smallmouth bass nests built during the two distinct spawning seasons. Smallmouth bass built 463 nests (1 10.2 n e s t s h shoreline) as water temperature was rising toward 20°C. During the summer spawning period, 24 nests (5.7 nestslkm shoreline) were constructed between 1 1 August and 29 August as water temperature was falling. Nests built in summer were significantly farther from shore, in deeper water, farther from cover, larger in diameter, and built by larger males than in the spring. INTRODUCTIONThe smallmouth bass (Micropterus dolomieu) has adapted to life in northtemperate lakes by adopting a spring spawning behavior. Rising spring water temperature triggers nest building by males, usually in shallow, gravel areas, and often associated with physical cover to increase survival on nests (Hubbs and Bailey 1938, Scott and Crossman 1973, Baylis et al. 1993). The largest males spawn first (Ridgway et al. 1991), procuring larger broods, which presumably results in better survival and fitness for offspring (Wiegmann et al. 1992). It is also presumed that producing eggs earlier confers greater fitness to offspring because earlier-spawned individuals can attain greater size during the growing season by acquiring more food and can reduce size-dependent mortality (Oliver et al. 1979, Latto 1992, Ludson and DeVries 1997. Because mortality of young-of-year smallmouth bass can exceed 95% by early fall (Frey et al. 2003), increased growth of earlier-spawned young-of-year is believed to translate into increased survival.Another presumed ecological advantage that the larger, earlier-spawned young-ofyear smallmouth bass have is that by attaining a larger size these fish are more prepared for the rigors of over-winter survival, a period of time when little feeding occurs (Oliver et al. 1979, Shuter et al. 1980. Shuter et al. (1 980) demonstrated through modeling and in laboratory studies that smallmouth bass survival to later year classes is contingent on growing large enough by their first fall to sustain them through the winter. They also used this work to explain the northern limit of smallmouth bass distribution. Lakes north of the 16.6"C mean July air temperature isotherm generally had lower over-winter survival because young-of-year were not able to acquire enough lipid stores during the short growing season. They concluded that smallmouth bass cannot become established in lakes with successive winter-induced year-class failures.It seems logical from a bioenergetics standpoint that spring-spawned fish should survive best and production of these individuals should regulate future year classes and

– We assessed hatch dates and daily growth rates of age‐0 smallmouth bass from two glacial lakes over a 3‐year period. Hatching durations (19–27 days among years) of smallmouth bass occurred from late May until late June. Mean daily growth rate of age‐0 smallmouth bass ranged from 0.56 to 1.56 mm·day−1. Correlation analysis indicated that hatch date had little effect on daily growth rates. Hatch date was significant in explaining variation in total length (TL) of age‐0 smallmouth bass at time of capture in only three of six cases and hatch date never explained >50% of the variation in bass length. Daily growth rate significantly explained variation in smallmouth bass TL at time of capture in all six models, accounting for 31–86% of the variability in bass length. Our findings suggest that size structure of age‐0 cohorts in some populations may be more strongly regulated by variation in individual daily growth rate than by hatch timing.

“…Among these factors, water temperature is an influential component of growth in fish populations (Picard et al, 1993;Dutta, 1994;Oxenford et al, 1994;Radtke & Fey, 1996). Because there can be a large thermal gradient from higher to lower latitudes within the geographic range of any species, there is a potential for differences in growth rates among populations.…”

Growth rate responses of Missouri and Lower Yellowstone River fishes to a latitudinal gradient

Notropis atherinoides, freshwater drums Aplodinotus grunniens, river carpsuckers Carpiodes carpio and saugers Stizostedion canadense collected in 1996-1998 from nine river sections of the Missouri and lower Yellowstone rivers at two life-stages (young-of-the-year and age 1+ years) were significantly different among sections. However, they showed no river-wide latitudinal trend except for age 1+ years emerald shiners that did show a weak negative relation between growth and both latitude and length of growing season. The results suggest growth rates of fishes along the Missouri River system are complex and could be of significance in the management and conservation of fish communities in this altered system.
