Among-individual diet variation within a lake trout ecotype: Lack of stability of niche use
<p>In a polymorphic species, predictable differences in resource use are expected among ecotypes, and homogeneity in resource use is expected within an ecotype. Yet, using a broad resource spectrum has been identified as a strategy for fishes living in unproductive northern environments, where food is patchily distributed and ephemeral.<span> We investigated whether specialization of trophic resources by individuals occurred within the generalist piscivore ecotype of lake trout from Great Bear Lake, Canada, reflective of a form of diversity</span>. Four distinct dietary patterns of resource use within this lake trout ecotype were detected from fatty acid composition, with some variation linked to spatial patterns within Great Bear Lake. Feeding habits of different groups within the ecotype were not associated with detectable morphological or genetic differentiation, suggesting that behavioral plasticity caused the <span>trophic differences</span>. A low level of genetic differentiation was detected between exceptionally large-sized individuals and other piscivore individuals. We demonstrated <span>that individual trophic specialization can occur within an ecotype inhabiting </span>a geologically young system (8,000–10,000 yr BP), a lake that sustains high levels of phenotypic diversity of lake trout overall.<span> The characterization of niche use among individuals, as done in this study, is necessary to understand the role that individual variation can play at the beginning of differentiation processes.</span></p>
Digesta and Plasma Metabolomics of Rainbow Trout Strains with Varied Tolerance of Plant-Based Diets Highlights Potential for Non-Lethal Assessments of Enteritis Development
<p>The replacement of fishmeal in aquafeeds is essential to the sustainability of aquaculture. Besides the procurement of alternative protein sources, fish can also be selected for better performance on plant-based alternative diets. Rainbow trout (<em>Oncorhynchus mykiss</em>) is one such species in which the strain ARS-<em>Sel</em>has been selected for higher growth and enhanced utilization when fed soy-based diets. The aim of this study was to compare fish growth, and plasma and digesta metabolomes between the ARS-<em>Sel</em>and two commercial strains (CS-1 and CS-2), when fed a plant-protein diet (PM) and a fishmeal-based diet (FM) and correlate them with the onset of enteritis. An NMR-metabolomics approach was taken to assess plasma and digesta metabolite profiles. Diet and strain showed significant effects on fish growth, with the ARS-<em>Sel</em>fish receiving the PM diet reaching the highest final weight at sampling. Multivariate analysis revealed differences between plasma metabolite profiles of ARS-<em>Sel</em>and CS (CS-1 considered together with CS-2) PM-fed groups in the early stages of the enteritis development, which was confirmed by a histological approach. In digesta, no differences were observed between groups. As reported in previous studies the ARS-<em>Sel</em>strain performed better than the commercial strains when fed the PM diet. </p>
Diet overlap among non-native trout species and native Cutthroat Trout (Oncorhynchus clarkii) in two U.S. ecoregions
<p>The invasion of freshwater ecosystems by non-native species can constitute a significant threat to native species and ecosystem health. Non-native trouts have long been stocked in areas where native trouts occur and have negatively impacted native trouts through predation, competition, and hybridization. This study encompassed two seasons of sampling efforts across two ecoregions of the western United States: The Great Basin in summer 2016 and the Yellowstone River Basin in summer 2017. We found significant dietary overlaps among native and non-native trouts within the Great Basin and Yellowstone River Basin ecoregions. Three orders of invertebrates (Ephemeroptera, Trichoptera and Diptera) composed the majority of stomach contents and were responsible for driving the observed patterns. Great Basin trout had higher body conditions (k) and non-native Great Basin trout had higher gut fullness values than Yellowstone River Basin trout, indicating a possible limitation of food in the Yellowstone River Basin. Native fishes were the least abundant and had the lowest body condition in each ecoregion. These findings may indicate a negative impact on native trouts by non-native trouts. We recommend additional monitoring of native and non-native trout diets, regular invertebrate surveys to identify the availability of diet items, and reconsidering stocking efforts that can result in overlap of non-native fishes with native cutthroat trout.</p>
