Asian Carp and the Great Lakes Region

Description: Four species of non-indigenous Asian carp are expanding their range in U.S. waterways, resulting in a variety of concerns and problems. Three species—bighead, silver, and black carp—are of particular note, based on the perceived degree of environmental concern. This report examines current controversy relating to what measures might be necessary and sufficient to prevent movement of Asian carp from the Mississippi River drainage into the Great Lakes through the Chicago Area Waterway System. Movement of Asian carp into the Great Lakes is ultimately of concern because increased numbers of carp in the Great Lakes increases the risk that Asian carp will establish reproducing populations in these waters. Bills have been introduced in the 111th Congress to direct actions to avoid the possibility of carp becoming established in the Great Lakes.

State of Idaho Augmented Anadromous Fish Health Monitoring, 1987 Annual Report.

Description: The anadromous fish health monitoring program began in full operation in January 1988 after the hiring of the lead pathologist. This short operating period limits the amount of information available at the time of this writing. Pre-release sampling of smolts revealed the presence of several sub-clinical pathogens. Organosomatic analysis results demonstrated no major abnormalities in the examined stocks. The results of the 1988 steelhead broodstock sampling are still pending.

Life History Allocation of Energy to Growth and Reproduction in Gizzard Shad, Dorosoma cepedianum, in North Central Texas

Description: Life history allocation of energy to growth and reproduction was determined for female gizzard shad. Absolute caloric energy allocated to eggs increased with age. The relative amount of production energy directed to reproduction increased with age up to 5 years and then decreased. Seasonal variation in lipids was studied. Quantitative changes occurred in ovarian lipids during the reproductive cycle. Carcass lipids varied seasonally. Age of sexual maturity was 3 years. Delayed maturity is attributed to high allocation of energy to growth enabling shad to outgrow intense competition and predation in pre-reproductive ages; there is little competition and predation in reproductive shad. Growth rates and condition factors indicated constant availability of food seasonally.

Responses of Selected Texas Fishes to Abiotic Factors, and an Evaluation of the Mechanisms Controlling Thermal Tolerance of the Sheepshead Minnow

Description: Low oxygen tolerances of ten fishes were estimated using an original nitrogen cascade design, and reciprocally transformed to express responses as ventilated volume necessary to satisfy minimal oxygen demand (L·mg O2^-1). Values ranged from 0.52 to 5.64 L·mg^-1 and were partitioned into three statistically distinct groups. Eight stream fishes showed moderately high tolerances reflecting metabolic adaptations associated with stream intermittency. Juvenile longear sunfish and two mollies comprised the second group. High tolerance of hypoxia may allow juvenile sunfish to avoid predation, and mollies to survive harsh environmental oxygen regimens. The sheepshead minnow was the most tolerant species of low oxygen, of those examined, explaining its presence in severely hypoxic environments.

The Roles of Genic Behavioral and Biochemical Mechanisms in the Adaption of Minnows of the Genus Notropis (Cyprinidae) to Temperature

Description: Electrophoretic variation at twenty gene loci, patterns of behavioral thermoregulation, and genotype-specific malate dehydrogenase kinetics were investigated among populations of the red shiner, Notropis lutrensis, and the blacktail shiner, N. venustus, collected from thermally altered and thermally unaltered portions of their ranges. Genic variation was found to be high among red shiners and low among blacktail shiners. The behavioral response of the blacktail shiner to temperature was fixed among the populations sampled, whereas the response of the red shiner was mutable. Finally, blacktail shiners have incorporated into their genome an Mdh-B allele which functions well at low temperatures; red shiners, displaying high levels of Mdh-B polymorphism, maintain a more complex set of allozymes which function well over a wide range of environmental temperatures. These data are consistent with reported ecotypic distributions of the species in Texas waters; i.e., blacktail shiners occur in cool, thermally static habitats, and red shiners are tolerant of wide temperature ranges.

The Influence of Stream Regulation on Genic Differentiation and Thermal Tolerance in the Red Shiner, Notropis Lutrensis

Description: Genetic variation and thermal tolerance were surveyed for variation attributed to nonuniform selection pressures for five populations of the red shiner, Notropis lutrensis, collected from regulated and unregulated portions of a Texas river. Populations within 30 km of a hypolimnion-release dam that experience large thermal perturbations were found to have higher levels of heterozygosity, higher levels of polymorphism, significantly depressed levels of upper thermal tolerance endpoints, and greater variances in tolerance endpoints. These populations have evolved enzyme systems differing from the unregulated populations in response to a variable and depressed thermal regime.

Reciprocal Influences of Temperature and Copper on Fathead Minnows (Pimephales promelas)

Description: Acclimation temperature had a significant effect on the lethality of copper to fathead minnows in replicated 96-hour lethality tests. Lowest median lethal copper concentrations (LC50) were recorded at 12 and 22°C, with LC50s at 5 and 32°C at least 140 μg/1 higher. This research found LC50 copper concentrations in the 300 to 500 μg/1 range and a polynomial relationship between LC50s and acclimation temperature. Following a 24-hour exposure to three sublethal concentrations of copper, critical thermal maxima (CTMax) were tested in minnows acclimated to four temperatures. Sublethal exposure to copper significantly decreased the CTMaxs relative to controls at three of the four temperatures. Control CTMaxs ranged from 28.6 to 40.4°C and increased 0.46°C for each 1°C increase in acclimation temperature.

An Alternative Approach to Monitoring Fish and Fish Habitat in the Inland Northwest, 1999 Annual Report.

Description: The development of efficient and effective monitoring protocols will depend, in part, upon successfully incorporating multiple research and management goals across several disciplines. Decision analysis has these abilities and can be used to examine the potential effects of alternative management activities, identify candidate monitoring variables, and estimate the value of monitoring or conducting additional studies. The author demonstrates the utility of decision analysis for monitoring and adaptive (i.e., experimental) management with an example of a timber harvest decision. Example models were generated using previously reported relationships and Monte Carlo simulation and the value of sampling (e.g., monitoring) was estimated via Baye's Rule. He concludes that the decision analysis can be a powerful tool for developing a future effectiveness monitoring protocols and should be considered by natural resource managers prior to adopting a monitoring strategy.
