Abstract:
Trout populations in 29 lakes in Glacier National Park were identified by meristic and electrophoretic analyses to assess the extent of introgressive hybridization between introduced nonnative trout and the indigenous cutthroat trout, Salmo clarki lewisi. Native cutthroat trout remain in 16 lakes draining to the North and Middle forks of the Flathead River; no native trout were found east of the Continental Divide. Introduced Yellowstone cutthroat trout, Salmo clarki bouvieri, occur in six headwater lakes. Hybrid populations, including both S. c. lewisi × bouvieri and S. clarki × S. gairdneri, inhabit six lakes. Hybridization between native and introduced trouts has been minimal, apparently due to strong selective pressures favoring the indigenous genotype. Close agreement was observed between the meristic and electrophoretic results.

Abstract:
During the last 150 years, the trout-culture industry focused on enhancing trout populations by stocking, in response to the growing anglers’ demand and the habitat degradation associated to the rapid urbanization and hydropower development. The industrialized north of Italy, home to the Italian Alpine and subalpine trout populations, is the source of most of the revenues of the national trout-culture industry. Its rapid growth, and the massive introduction of non-native interfertile trouts eroded the genetic diversity of native lineages, leading to harsh confrontations between scientists, institutions, and sportfishing associations. We review here the state of the art of the taxonomy and distribution of the northern Italian native trouts, presenting both scientific results and historical documentation. We think the only native trouts in this region are Salmo marmoratus, widespread in this region, plus small and fragmented populations of S. ghigii, present only in the South-western Alps. We strongly recommend the interruption of stocking of domesticated interfertile non-native trouts in this area, and recommend the adoption of Evolutionary Significant Units for salmonid fishery management. We further propose future research directions for a sustainable approach to the conservation and ecosystem management of the fishery resources and inland waters of northern Italy.

Abstract:
The growth hormone (GH)/insulin-like growth factor (IGF) endocrine axis regulates the cellular growth and organ development in related to changing environmental conditions and age. The aim of this study is to determine growth factor genes, which are biological markers of growth in muscle and liver of rainbow trout (Oncorhynchus mykiss) in different seasonal temperatures and age ranges and the reveal of the relationship between serum cortisol (COR) levels from stress parameters. No difference was found in serum COR levels between the groups with respect to temperature and age. Serum GH levels were found to be higher in the summer juvenile trout compared to the winter juvenile and adult trouts. There was no difference in liver growth hormone receptor (GHR) mRNA levels of juvenile and adult trouts in winter while insulin-like growth factor-I (IGF-I) and insulin-like growth factor-II (IGF-II) mRNA levels in liver and muscle tissues were found to be higher in juvenile trout compared to adults. Among trout of different ages, GHR, IGF-I and IGF-II mRNA levels in liver in summer were higher for juvenile trout compared to adults. Muscle IGF-I mRNA levels in summer were higher in adult trout compared to juveniles. IGF-II mRNA levels in liver and muscle tissues of juvenile trout showed an increase in winter compared to in summer. While the GHR and IGF-II mRNA levels in the liver tissue of adult trout were observed to higher in winter compared to summer, IGF-I mRNA levels were found to be higher in summer. GHR, IGF-I and IGF-II mRNA levels in muscle tissue of adult trout were found to be higher in summer than in winter. This study indicated that juvenile and adult rainbow trout (Oncorhynchus mykiss) are adapted to both winter and summer temperature and that GHR, IGF-I and IGF-II genes are highly expressed.

Abstract:
Rainbow trout Oncorhynchus mykiss (Walbaum, 1792) and brown trout Salmo trutta Linnaeus, 1758 are popular aquaculture species worldwide. At the same time, it is known that when these species enter natural water bodies, they are able to form self-reproducing populations and cause significant damage to native fauna due to food competition, hybridization with native species, and predation. In the basin of the Upper Ob in the second half of the twentieth century, there was not only a large aquaculture farm specializing in trout but also work was carried out to introduce trout into natural water bodies: lakes in the basins of Lake Teletskoye and the Katun river. It is known about the formation of a self-reproducing population of brook trout in Lake Lebedinoe (in the basin of the Pervaya Koksha River, a second-order tributary of the lower reaches of the Katun River), which still exists. Currently, rainbow trout is a popular object of aquaculture in southern Siberia; it is grown mainly for the purpose of organizing recreational fishing, often in water bodies that are not isolated from the river network. This determines the regular ingress of this species into rivers. Nevertheless, currently no evidence of natural reproduction of trouts in natural water in the Upper Ob basin, except in Lake Lebedinoe. However, given the high risks associated with the potential invasiveness of trouts, it is necessary to recommend a cautious attitude towards the distribution of these species and to provide for an environmental impact assessment of projects related to their cultivation in water bodies of Western Siberia.

Abstract:
Alien fish introductions, conducted towards the ichthyofauna enhancement in local drainages, have been occasionally proved harmful for the indigenous freshwater fish populations. The present study was designed to assess the impact of stocking activities, carried out in the past decades with fingerlings originating from Acheloos river hatcheries, on the native trout (Salmo sp.) populations of Nestos River, Greece. Trout specimens collected from several tributaries of Nestos River and were analyzed by means of PCR-RFLP and sequencing targeting the mitochondrial ND5-ND6 genes and the entire control region, respectively. It should be mentioned that trouts from Acheloos mainly belong to the marmoratus mitochondrial DNA (mtDNA) lineage, while the autochthonous trouts from Nestos belong to the Adriatic lineage. Both methodologies demonstrated that most samples from the three tributaries located at the lower part of Nestos constitute offspring of the fingerlings transferred from Acheloos hatcheries. Therefore, these tributaries have been strongly affected by stocking activities with a potential complete loss of their autochthonous trout. On the other hand, it seems that trout populations from higher altitude tributaries have not been affected by stockings. Hence, efforts should be undertaken in order to prevent the prevalence of the non-indigenous translocated Salmo in higher altitude tributaries, in conjunction with a management plan designed for the total trout populations from the area, speaking of which it has been recently included to the National Park of Rodopi Mountains.

Abstract:
Weissellosis is an emergent disease caused by Weissella, a Gram-positive bacteria correlated with hemorrhagic illness and mortality in farm-raised trout in several countries. The current study reports the first outbreaks of weissellosis by Weissella ceti in rainbow trout (Oncorhynchus mykiss), which caused severe mortalities in trout farms in Colombia between May 2016 to June 2019. The disease occurred in several farms irrigated by the same river where temperatures were above 17 °C. Symptoms of the disease were limited almost exclusively to trout above 250 g. The clinical signs consisted of lethargic and anorexic fish, swimming in circles at the surface or against the walls. Pathological findings were mainly ocular lesions like bilateral exophthalmia, periocular and intraocular hemorrhage, lenticular opacity and corneal rupture usually leading to blindness, muscular hemorrhages and necrosis. Microbial isolating from eye, brain, kidney, liver and muscle was performed and W. ceti was confirmed by amplification and sequencing of the 16S rRNA. The aim of this work was to characterize the Weisellosis by Weissella ceti in trouts in Colombia, including microbiological isolating, molecular analysis, gross and microscopic characterization.

Abstract:
The introduction of the use of molecular data has caused debates on the taxonomy of Corsican and Sardinian trouts, also referred to as Tyrrhenian trouts (i.e. Salmo trutta, Salmo macrostigma, Salmo cettii). A recent study by Delling et al. (2020) (Morphologic and genetic characterization of Corsican and Sardinian trout with comments on Salmo taxonomy. Knowl Manage Aquat Ecosyst 421: 21) introduces important evidence regarding the taxonomy of these populations. However, their subsequent denomination as Salmo sp., that is, an undefined taxon, could have serious consequences on their future conservation management plans. Considering their threatened status, the Tyrrhenian trouts should be referred to as Salmo trutta until the ongoing taxonomic uncertainty can be unambiguously resolved. These populations must then be treated as an Evolutionary Significant Unit (ESU) or as an Operational Conservation Unit (OCU) for further conservation managements plans, as already done for other Mediterranean trout lineages.

Abstract:
Reactive oxygen species contribute to kill of microorganisms. Their activity is usually measured by their capacity to reduce nitroblue tetrazolium into formazan. The incubation time to allow nitroblue tetrazolium reduction by reactive oxygen species usually ranges from 30 to 60 min. The aim of our study was to determine the kinetics of formazan formation, to determine the shortest incubation time possible, and to find if astaxanthin negatively affects the availability of reactive oxygen species (and defense mechanisms of fish). The blood/nitroblue tetrazolium method is based on nitroblue tetrazolium reduction into formazan by reactive oxygen species present in blood. Formazan can be spectrophotometrically measured, allowing quantification of reactive oxygen species. Reactive oxygen species were measured in blood samples from 30 trout intramuscularly injected with astaxanthin (0.3 mg/100 g of fish) (experimental group) and 30 non-injected trout (controls). Results indicated that in trout non-treated with astaxanthin, the plateau of formazan production was reached after 20 min of incubation. Trout intramuscularly injected with astaxanthin showed the following: on Day 1 after astaxanthin injection, the kinetics were slower but finally reached a plateau similar to astaxanthin-free trouts, and by Day 11 the plateau was significantly higher after 60 min incubation. In conclusion, the kinetics curves here reported allow reducing incubation time of the method to only 20 min in antioxidant-free trout and, on the other hand, our results also revealed that astaxanthin can be used to improve flesh colour in salmonids without affecting reactive oxygen species availability and therefore the defense mechanisms of trout.

Abstract:
Brown trout (Salmo trutta) and rainbow trout (Oncorhynchus mykiss) fry and juveniles were episodically or continuously exposed to a metals mixture (Zn, Cu, Pb, Cd): the concentrations and ratios of the metals, and variations in water quality (pH, hardness), were selected to represent conditions measured during episodic storm events in the Clark Fork River, Montana. Brown trout fry were more sensitive (lower LC50) than rainbow trout fry to the metals in 8-h exposures with constant hardness and pH, but less sensitive to elevated metal concentrations in conjunction with depressed hardness and pH. Fry were more sensitive than juveniles when exposure was continuous, but neither life stage was clearly more sensitive when exposure was pulsed. Whole-body concentrations of K+ and Ca2+ but not Na+ were significantly depressed in fry exposed to metals. Results support the hypotheses that changes in water quality during thunderstorms are lethal to fry and juvenile life stages of brown and rainbow trouts and that the relative sensitivity of the species to the metals mixture may explain their distributions in the Clark Fork River. Low-frequency extreme conditions may effectively act as a bottleneck on the viability of populations whose relative sensitivities to such extremes may control distributions of species in a system.

Abstract:
Selenium (Se) is an essential element, toxic at concentrations only slightly above those required. It can become detrimental to fish health when available in excess in the aquatic environment. This study examined the effects of Se on adult female rainbow trout, brook trout, and cutthroat trout fed Se-methionine for five months, and on their larvae. Differences between fish species and between tissues were observed in the accumulation of Se in adults, and dose-dependent effects of Se on plasma thyroid hormone concentrations in brook trout, gonad size in all three species, and indicators of oxidative stress in rainbow trout and cutthroat trout, were detected. Survival of larvae and swim-up success decreased with increasing egg Se concentrations in rainbow trout and cutthroat trout, however, the same effects were not observed in brook trout. Data from this study provide new evidence for species-specific Se accumulation and toxicity in salmonid fish.

Abstract:
To evaluate whether nonnative brook trout, Salvelinus fontinalis, and native westslope cutthroat trout, Oncorhynchus clarkii lewisi, occupied a similar niche I developed and evaluated finite population correction factor (FPC) methods for estimating fish biomass in small streams (< 5 m wide). These new FPC methods take advantage of the fact that relatively high proportions of the total population are captured and can be measured and weighed during removal population estimation. Biomass estimates for these FPC methods had much smaller coefficients of variation than the traditional method for both field and simulated data. Coverage by 95% confidence intervals for the FPC methods were much closer to the 95% nominal level than for the traditional method, especially when capture probabilities were higher than 0.5. Using simulated data, I found that removal population estimates deviated significantly from true population sizes, but that these deviations clustered near zero when the ratio of captured fish to the estimated number was 0.7 or higher. Six to eleven multi-pass electrofishing efforts successfully eradicated nonnative brook trout from 1.7 to 3.0-km treatment reaches of four streams. Brook trout were eradicated to conserve native westslope cutthroat trout and evaluate competitive influences of brook trout on westslope cutthroat trout. Eradication success was related to stream size, distribution and abundance of brook trout, years of treatment, number of treatments per year, amount of cover, cover reduction efforts, and beaver ponds. Total trout biomasses significantly increased in all three streams after brook trout were eradicated, indicating that brook trout and cutthroat trout probably have similar niches and that interference competition may be occurring. Densities of juvenile and adult cutthroat trout were significantly (P < 0.05) and negatively affected by densities of juvenile and adult brook trout. I did not find a difference between cutthroat trout and brook trout density effects on body condition of cutthroat trout. I found evidence for size-asymmetric competition in one stream, but not in another. Interspecific competition between brook trout and cutthroat trout appeared to be as strong as intraspecific competition within cutthroat trout, providing insight into one mechanism by which brook trout might displace cutthroat trout.

Abstract:
Brook trout invasion into bull trout streams is variable, and likely influenced by a suite of biotic and abiotic factors. Field observations revealed that brook trout dominated the fish community over bull trout in warmer sites that had undercut banks; in contrast, bull trout dominated in colder sites that had a high amount of large substrate cover, and where alternate non-native species were present. Laboratory studies of competition between the two species revealed that bull trout use a scramble foraging tactic, whereas brook trout use a territorial tactic. Bull trout outcompeted brook trout when fish density was low and habitat complexity was high, as this scenario reduced the effectiveness of the aggressive territorial foraging strategy of brook trout. Bull trout from a migratory population competed more successfully against brook trout and had higher rates of oxygen consumption than those from a resident population. This combined field-lab study points to some of the abiotic and biotic factors that affect competition between the two species, and may influence the outcome of brook trout invasion into bull trout streams.

Abstract:
The article presents an analysis of a comprehensive study of the growth and development indicators of rainbow trout grown on granulated feeds using a plankton microalgae suspension concentrate Chlorella vulgaris (GKO) as a bioadditive. The possibility of using the studied biopreparation in the feeding ration of trout as an active additive with an immunocorrecting effect has been proven. The use of a Chlorella suspension at a concentration of 10 ml / kg increases the survival and resistance of trout jewels, as well as the general strengthening of the immune background of the fish organism.

Abstract:
The Cameron Peak Fire and East Troublesome Fire of 2020 were the two largest wildfires in Colorado history. They burned approximately 9% of the Rocky Mountain National Park, raising a concern for trout populations that currently support recreational fishing and success of on-going and future efforts to conserve native trout populations. We inventoried habitat characteristics and biological communities at 19 sites in summer of 2021 and a subset of 11 sites in summer of 2022 to characterize wildfire impacts on aquatic resources, with the focus on characterizing trout population responses. There was much site-to-site variation in the trout population responses, but when averaged across sites using Bayesian hierarchical models, trout abundance significantly decreased in 2021 relative to pre-fire abundance, and the decrease was more evident in smaller trout (75-125 mm total length) than in larger trout (> 125 mm). From 2021 to 2022, trout abundance generally increased, although the increase was statistically significant only in small trout. Although pre-fire data were lacking for benthic macroinvertebrates, their abundance and composition was comparable between burned sites and those outside the fire perimeter, indicating that prey availability to trout was not limited. Our results show that trout abundance decreased post-fire, but trout populations were not eradicated and are likely in a recovery phase. These data cannot be used to argue for stocking trout to sustain recreational fisheries or discontinuing native trout conservation actions including the Poudre Headwaters Project.

Abstract:
The population status of the sea-migrating trout is in many cases unknown. Where recruitment status is known, many of the populations are at low levels, especially in the Bothnian Sea. There is a need to obtain more knowledge to be able to manage sea trout sustainably in the long run, as the species is very popular among anglers. It has been suggested that “index streams” for sea trout should be established (Magnusson et al. 2020, 2023, Magnusson 2023), where data on recruitment, smolt migration and spawning migration are collected and analyzed. The purpose of this report is to gather and compile information on typical sea trout streams and to suggest index streams that may be suitable for data collection. In order to identify suitable index streams for sea trout, information has been collected from county board representatives and others with good local knowledge. This information has been compiled by county and is presented in this report. In addition, an attempt was made to identify potential index streams based on data from the Swedish database for electrofishing in streams (SERS) and Trout Habitat Score (THS) criteria. In Norrbotten, electrofishing sites in known sea trout streams are largely lacking, hence an attempt to identify potential trout streams was made by identifying riffle sections with the help of geographic information systems (GIS). As the results differ to some extent between the different methods, it is recommended that people with good local knowledge are involved in the establishment of index streams for sea trout. The report is based on analysis of electrofishing data in combination with interviews with experts carried out between October 2018 and January 2019, which has since been supplemented with further information.
