“…Causes for reductions in stream quality include introductions of exotic organisms and novel diseases, permanent changes in stream velocity and volume, deterioration of water quality, and alteration of habitat (Lowe et al 1967;Moyle et al 1986;Rinne et al 1986;Douglas et al 1994). In particular, rising water temperatures have become a concern, compelling fisheries managers to evaluate the effects of increasing water temperatures on fish health and survival (Barber et al 1970;Poole and Berman 2001;Chatterjee et al 2004).…”

Comparison of Upper Thermal Tolerances of Native and Nonnative Fish Species in Arizona

2006

We used a lethal thermal method to estimate the upper thermal tolerances of 11 native and 7 nonnative fish species found throughout southern Arizona. Fish were acclimated to 258C and 308C. For all species tested, an increase in acclimation temperature resulted in a higher thermal tolerance value. Among the species acclimated to 258C, desert pupfish Cyprinodon macularius, western mosquitofish Gambusia affinis, and Gila topminnow Poeciliopsis occidentalis were most tolerant to high temperature. Speckled dace Rhinichthys osculus, spikedace Meda fulgida, and loach minnow R. cobitis were least tolerant. Many native species demonstrated a limited ability to extend their upper temperature tolerances via acclimation. Our data suggest that several native species may be sensitive to increasing annual and large daily temperature fluctuations in Arizona's streams and rivers. Although southwestern native fishes were previously believed to be tolerant to high temperature due to their evolution in desert environments, this study suggests that many of these fishes are less tolerant than previously thought. In addition, many fishes introduced from the eastern United States had higher temperature tolerances than some of the native desert species tested. Increases in stream temperatures in Arizona could reduce the habitat available for native fishes and therefore may favor those nonnative species with higher thermal tolerances.

“…Because of its midwater habitat preferences, M. fulgida is expected to exhibit greater capacity than T. cobitis for long-distance migration. Like that of T. cobitis, the majority of spawning activity in M. fulgida occurs from April through July (Barber et al 1970;Anderson 1978), although occasionally young-of-year will spawn during the autumn months.…”

Abstract.-Geographic patterns of genetic variation (mitochondrial DNA [mtDNA] and allozymes) were used to examine effects of intrinsic characteristics (e.g., vagility, habitat specificity, and reproductive behaviors) and extrinsic factors (e.g., climatic and geological history) on population fragmentation.The three species of cyprinid fishesexamined (Tiaroga cobitis, Meda fulgida, and Agosia chrysogaster) occupied similar historical ranges within the lower Colorado River drainage, but differ in intrinsic characteristics conducive to population fragmentation. Relationships among populations were similar across species, reflecting common historical influences, but results indicate the distribution of variation among species is strongly affected by intrinsic characteristics. Variation within two species (T. cobitis and M. fulgida) is subdivided among populations, suggesting little gene flow among rivers. In contrast, similarity of A. chrysogaster populations throughout the Gila River drainage supports the hypothesis that levels of gene flow are high for this species. Levels of mtDNA divergence were much higher than expected for both T. cobitis and A. chrysogaster suggesting long-term isolation of geographic regions. These results indicate that both long-term and short-term extrinsic factors have shaped basic patterns of variation within these fishes; however, the intrinsic characteristics of each species have strongly affected the population genetic structure of these fishes.

“…Blinn et al (1998) noted that Little Colorado spinedace spawned in gravel that averaged 6.4 ± 0.37 mm in diameter. Spawning activity over gravel has been observed in spikedace as well (Barber et al 1970). However, woundfin Plagopterus argentissimus chose larger spawning substrates (5-10 cm diameter), rather than gravel, sand, or larger-diameter rocks (Greger and Deacon 1982).…”

“…Several fish species are able to discriminate between kin and nonkin (McKaye and Barlow 1976;Barnett 1981;Quinn and Busack 1985), preferring to mate with nonkin and showing less aggression toward kin (Brown and Brown 1993). Barber et al (1970) noted that spikedace begin spawning at age 1. The warmer temperature regimen in southwestern U.S., where spikedace is native, probably gives the species more time for growth and gonadal development than more northern species like northern leatherside chub.…”

We present 4 years of data that refine aquaculture protocols for the northern leatherside chub Lepidomeda copei, a species of conservation concern in the Intermountain West. Experiments examined life history traits (age at first spawning and thermal limits to egg hatching success) and aquaculture techniques (brood density, spawning substrate type and surface area, and feeding methods for fry). Tests showed that leatherside chub can reproduce as early as age 2. Multiple spawns per female during a year were also documented. Survival of eggs was compared at incubation temperatures of 18.4, 23.0, 24.6, and 26.8 • C. Eggs at 18.4 • C had the highest survival to hatching (54.0%); eggs at 26.8 • C had significantly lower survival (1.5%). Egg survival at 23.0 • C and 24.6 • C (32-33%) was significantly lower than survival at 18.4 • C. Aquaculture experiments showed that the mean total number of eggs produced did not significantly differ between brood densities of 8. 4 (1,246 ± 1,236 eggs [mean ± SD]) or 16.8 (2,224 ± 1,600 eggs) fish/m 3 . Studies showed that leatherside chub preferred spawning over natural cobble substrate to spawning over marble substrate. More eggs were recovered from a three-substrate tray treatment (1,350 cm 2 ) than from a single tray treatment (450 cm 2 ). Fry given brine shrimp Artemia spp. with probiotic bacteria or fed with an automated, more continuous drip feeder did not show any advantages in growth over time. Juveniles at rearing densities of 800, 1,700, and 3,400 fish/m 3 did not differ significantly in growth rates, deformities, or mortalities. This research provides general guidelines for rearing northern leatherside chub and some additional information on the species' life history.
