Diet during the first few months of life can have substantial effects on growth and survival of fishes. The purpose of our study was to examine the diet of age-0 tarpon in the North Inlet-Winyah Bay estuarine system, located near the northern extent of their distribution in the western Atlantic Ocean. We examined stomach contents to characterize tarpon diet and relate tarpon feeding to water temperature. The most important prey items based on the frequency of occurrence and proportion by weight indices were small fishes and crustaceans, whereas copepods were the most important prey based on the proportion by number index. Small age-0 tarpon (<span>(le)</span> 100 mm) consumed small crustaceans (copepods) while large age-0 tarpon (&gt; 100 mm) consumed larger crustaceans (shrimp) and age-0 tarpon of all sizes consumed fish. Most tarpon with empty stomachs were collected at temperatures &lt; 25 °C, whereas most tarpon with prey in their stomach were collected at temperatures &gt; 25 °C. The proportion of tarpon having at least one prey item in their stomach contents was greatest around 28 °C and declined at lower and higher water temperatures. Salt marsh habitats in the North Inlet-Winyah Bay estuarine system provide suitable food resources for age-0 tarpon. As water temperatures increase and tropical species, such as tarpon, expand their range, these coastal nursery habitats may become more important for tarpon growth and recruitment to the spawning stock.</p>","PeriodicalId":11799,"journal":{"name":"Environmental Biology of Fishes","volume":"124 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141509132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to understand the molecular mechanisms involved in the regulation of these arrests. In this context, we first comprehensively analysed the expression of genes using a transcriptomic approach to distinguish between two developmental trajectories: diapause induction and non-diapause induction. We focused on the process of diapause I induction by comparing the mRNA profiles at the maternal stage with those of diapause I-induced embryos, non-diapause I-induced embryos and embryos that had exited diapause I. Our analysis revealed approximately seven hundred transcripts that were differentially and exclusively expressed upon the induction of diapause I. The Gene Ontology (GO) categories of the gene-specific transcriptional regulator group, RNA metabolism, cytoskeletal protein and scaffold/adaptor proteins exhibited the highest representation among differentially expressed genes (DEGs) and coexpression analysis. Remarkably, the identification of different homeodomain transcription factors, cell cycle regulators and RNA processing/regulators as DEGs suggests that these regulators play important roles in <i>Garcialebias charrua</i> diapause I induction. Consistent with the results of the DEG analysis, the results of the Clust coexpression analysis revealed 5 and 3 patterns of diapause I-induced gene upregulation and downregulation, corresponding to 3939 and 1250 genes, respectively. Comparative expression analysis of genes and signalling pathways reported to contribute to diapauses in other species revealed that insulin/IGF, vitamin D, Wnt, polycomb and heat shock proteins are also involved in diapause I induction in annual killifish.</p>","PeriodicalId":11799,"journal":{"name":"Environmental Biology of Fishes","volume":"9 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141509131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, quantifying the effect of temperature on growth is challenging given differences among methodologies, metrics of growth, and their underlying assumptions. Using short term studies (2000–2002) in two Canadian populations of wild Atlantic salmon (Margaree and Miramichi rivers), we investigate whether different hierarchical modeling approaches influence the derivation of temperature-growth relationships, by contrasting seasonal growth trajectories (von Bertalanffy; VBGF) to size-at-age data models built with instantaneous growth rates. Size-at-age data analysed seasonally with the VBGF framework failed to detect an effect of temperature, whereas instantaneous growth rates from the same dataset were strongly related to temperature metrics. However, instantaneous growth rates cannot be used to extrapolate predictions into meaningful metrics for fisheries management (e.g., size at the end of the growing season). Nevertheless, we show that size at the end of the growing season can be predicted with VBGF models accounting for site-level variation, which in turn are related to temperature metrics, as observed for instantaneous growth rates. Taken together, these results show that combining these two approaches (size-at-age, growth rates) can circumvent their intrinsic drawbacks and reveal essential ecological patterns that may otherwise remain undetected. In cases where instantaneous growth rates are not available, relating predicted size-at-age from hierarchical VBGF to temperature provides an interesting alternative for detecting subtle environmental effects, even if the VBGF parameters or its residuals are unrelated to temperature metrics.</p>","PeriodicalId":11799,"journal":{"name":"Environmental Biology of Fishes","volume":"42 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141188546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By comparing populations from the wild with fish raised in a common-garden environment, we evaluated how genetic differentiation between populations and plasticity contributed to the phenotypic variation observed in nature. We quantified variation in the size of six organs (brain, eyes, gills, heart, liver, and gastrointestinal tract), routine metabolic rate, and body shape. We found evidence for genetic differences between populations impacting the expression of the majority of traits, in addition to or in interaction with phenotypic plasticity and other predictor variables.
