During May–June 1980 and June–July 1982, six fish species exited Rivière à la Truite, a major tributary of the lower Moisie River, Quebec, in highly synchronized emigrations. Species included longnose sucker (Catostomus catostomus), white sucker (C. commersoni), lake chub (Couesius plumbeus), juvenile sea lamprey (Petromyzon marinus), Atlantic salmon (Salmo salar) parr and smolt, and anadromous brook trout (Salvelinus fontinalis). In 1980, emigration for all species except the lamprey began on 27 May and ended by 9–11 June; lamprey movements began on 4–5 June and peaked on 10 June. Similar but slightly later patterns occurred in 1982. Onset of the runs in each year coincided with declining water levels and discharge. Thus species of widely different habits exhibit similar and highly synchronized migratory patterns, possibly in response to strong changes in stream environment.

A vertical slot fishway and two Denil fishways (of 10 and 20% slope) built into a weir on the Lesser Slave River (55°18′N, 115°45′W) were studied from May 12 to June 25, 1984, to determine how effectively these designs pass north-temperate, nonsalmonid fishes. Thousands of spottail shiner (Notropis hudsonius), substantial numbers (> 100) of northern pike (Esox lucius), longnose sucker (Catostomus catostomus), white sucker (Catostomus commersoni), immature yellow perch (Perca flavescens), and lesser numbers of burbot (Lota lota), adult yellow perch, lake whitefish (Coregonus clupeaformis), and trout-perch (Percopsis omiscomaycus) ascended the fishways. Walleye (Stizostedion vitreum) and goldeye (Hiodon alosoides), although probably moving extensively through the river, did not use the fishways. Although high water levels allowed most fish to surmount the weir, of those that chose the fishway, pike strongly preferred to ascend the Denil fishways and the two sucker species preferred to ascend the vertical slot. Therefore, a combination of several different fishways may be required for the most efficient passage of a wide variety of species. Plasma glucose and lactate measurements on pike revealed that ascending the Denil fishways was only moderately stressful for these fish.

Major movements of trout into Ellerslie Brook, Prince Edward Island, were in April, June–July, and November; and out in May and October to early January. Some movements were preponderantly in one direction; others involved trout making simultaneous movements up- and downstream. Mean length of trout in movements was 16.8 cm., predominantly age II. Trout were short-lived and few survived to make repeated movements. About 50% of trout making return movements did so within a month. Percentage of Ellerslie-reared trout which ran to salt water varied from 12 to 35 over a 6-year period. There was inconclusive evidence of a heritable propensity to sea-running. After descending into the estuary, few trout left for open coastal waters. Short-distance movements resulted in population shifts in the brook in summer which were not detected in traps at mouth of stream.Movements of trout between fresh and salt water were very closely associated with rise and fall of the water level in the brook, but not with height of water. Movements in spring and early summer were into preferred temperature. Although marked changes in water level occurred, few trout moved in winter after becoming acclimated to a water temperature of 0 °C. or in summer when brook was at temperature of final preferenda. Continuance of movement for some time after 0 °C. was reached seemed related to slow rate of acclimation. Movements were both random and directed. For most movements trout appeared conditioned by temperature and stimulated by changing water levels. Trout moved largely at night. Other influencing factors were living space, maturation and spawning. Turbidity, salinity, tides, and handling were without apparent effects.

Hybrids between longnose sucker (Catostomus catostomus) and white sucker (C. commersoni), identified on the basis of intermediacy in several scale counts and in morphometric data, are recorded for the first time from Canada. The weakening of isolating mechanisms permitting hybridization was attributed to environmental factors, particularly species introduction and habitat disturbance. There was no evidence of swamping.

Ecology of the parasite fauna of two abundant nongame fish species, Catostomus catostomus (longnose sucker) and Catostomus commersoni (white sucker), from southwestern Lake Superior was examined. White sucker harbored a total of 17 parasite species compared with 8 species in longnose sucker. Echinorhynchus salmonis and Neoechinorhynchus crassus were the most abundant helminths in both sucker species. The only parasitic copepod found in this study, Ergasilus nerkae, was more prevalent in longnose sucker. In white sucker, Glaridacris catostomi, Capillaria catostomi, Ergasilus nerkae, Allocreadium lobatum, and Isoglaridacris bulbocirrus showed fluctuations in prevalence on a seasonal basis. Several helminth species showed a high degree of microhabitat overlap in the gut (e.g., A. lobatum, G. catostomi, and Echinorhynchus salmonis). Helminths that exhibited a higher mean intensity in certain sections of the intestinal tract included I. bulbocirrus in the anterior portion of the gut and Capillaria catostomi in the posterior region of the gut.

White (Catostomus commersoni) and longnose (C. catostomus) suckers possess diploid complements of 98 chromosomes, including metacentrics, submetacentrics, and acrocentrics. White sucker karyotypes differ consistently from longnose karyotypes by the presence of an additional four metacentrics. The karyotypes of the size and age at maturity of variants of white suckers were indistinguishable. Biochemically, longnose and white suckers are distinctive with respect to muscle myogens, hemoglobins, serum esterases, serum and muscle lactate dehydrogenases, and serum transferrins. The last group of proteins provides a clear genetic separation of the large-sized, late-maturing, and the dwarf, early-maturing white suckers. The former is polymorphic for serum transferrins.

Competing Risks Analysis

An understanding of how undesirable and desirable fish species respond behaviorally to turbulent flow in fishways would guide development of selective fish passage techniques. We applied high resolution computational fluid dynamics modeling and competing risks analysis towards the development of predictive selective passage models. Sea lamprey <i>Petromyzon marinus</i> (an invasive fish in the Great Lakes Basin, North America) upstream passage probability declined from 0.73 to 0.03 as flow conditions became increasingly turbulent, while declines in white sucker <i>Catostomus commersonii </i>(a native fish in the region) upstream passage probability were less substantial (0.53 to 0.44). Deploying a sea lamprey trap in the fishway did not effectively reduce sea lamprey upstream passage probability, though capture rate increased during trials with cooler water temperature and low total kinetic energy. Bifurcated fishways that maintain low turbulent flow in the entrapment route and high turbulent flow in the upstream passage route could increase the effectiveness of trapping sea lamprey in fishways as a means to advance selective passage goals.

Abstract Our recent studies have demonstrated reproductive dysfunction in white sucker (Catostomus commersoni), longnose sucker (C. catostomus) and lake whitefish (Coregonus clupeaformis) populations exposed to bleached kraft mill effluent (BKME). Although all three species show elevated levels of hepatic mixed function oxygenase (MFO) activity and depressed circulating steroid levels, we have been unable to provide clear evidence of whether these two events are directly linked to whole organism changes. Although depressed steroid levels appear to be linked to delayed sexual maturity, changes in fecundity and reduced secondary sexual characteristics in white sucker and lake whitefish, longnose sucker show no impacts of reduced steroid levels on reproductive performance. Installation of secondary treatment at this pulp mill did not alleviate the steroidal dysfunction or MFO induction. However, samples collected after a two week maintenance shutdown showed a return to reference levels of MFO activity in both sexes and of steroid levels in male fish. The relationship between elevated MFO activity and depressed steroid levels is unclear, but detailed experiments suggest that the two phenomena are not directly linked. White sucker show depressed steroid production and impaired reproductive regulation independent of MFO activity.

From a survey of 12 lakes containing brook trout, Salvelinus fontinalis, 12 lakes containing brook trout and creek chub, Semotilus atromaculatus, and 13 lakes containing brook trout and white sucker, Catostomus commersoni, we built seven multiple linear regression models to account for the mean percent weight of different prey categories in the diet of brook trout. Presence of chub and sucker, zooplankton community structure, sampling date, morphoedaphic index, and the importance of rock outcrops accounted for 88% of the variation in weight of zoobenthos eaten by trout, which was the preferred prey in allopatry. Thirty percent of the variation in weight of zooplankton eaten by trout was explained by the importance of macrophytes and other refuges for fish. Models for amphipods, dipteran pupae, swimming insects, terrestrial insects, and prey-fish explained between 36 and 63% of the variation. The presence of white sucker or an index of their impact (mean length or density of Cladocera) and the characteristics of littoral habitats appeared in six of seven models. Littorasl habitats seemed particularly determinant for the inclusion of prey-fish in the diet, more prey-fish being eaten when regufes were abundant. Variables related to lake morphometry and physicochemistry appeared less regularly in the models.

Swimbladder gas samples were analyzed from 10 species of fish caught at various depths extending from the surface to 486 ft. in Lake Huron and adjoining waters. The physoclists studied, yellow perch and burbot, had gas compositions which agreed with previous findings. From progressively greater depths, these displayed decreasing nitrogen percentages and increasing oxygen percentages. The physostomes, lake trout, lake whitefish, shallowwater cisco, deepwater cisco, bloater, American smelt, white sucker, and longnose sucker, displayed strikingly high percentages of nitrogen and correspondingly low percentages of oxygen at all depths. Carbon dioxide was found only in traces in both groups. Results of flotation pressures determined for American smelt, shallowwater cisco, and bloater indicated that most specimens were probably buoyant at depths of capture and that results of gas analyses were indicative of the gas compositions at depths of capture. Both physostomes and physoclists from the greatest depths of capture displayed swimbladder nitrogen pressures in excess of 0.8 of an atmosphere, the partial pressure of dissolved nitrogen in most natural waters. The excess was slight in physoclists but in physostomes it was nearly equal to the total (hydrostatic plus atmospheric) pressure.
