This symposium, created by the father of brown trout ecology, Dr. Javier Lobón-Cerviá and colleagues, grew out of intriguing conversations regarding the regulation of the population dynamics of salmonids, as long ago as the 1980s. The first symposium was in the quaint coastal town of Luarca, Spain, in 1998 and started out small with less than ~50 scientists in attendance. The second symposium, also more modest in numbers (~85 scientists), was held in 2006 in millenary Leon in the NW of Spain, a town proud of its history and its Cathedral of nearly 2000 square metres of stained glass and in-credible (free!) tapas. The third was in 2010 back in the stunning fishing town of Luarca, where our numbers grew substantially to more than 115, we moved into a fancy new conference hall, and we feasted on fresh seafood. The fourth was in 2015 and held in Girona (101 scientists), in the NE of Spain, where we all felt ethereal while giving our talks in a stunning cathedral-like hall and where we experienced the strong Catalonian culture and cuisine.

We met with old friends and new friends and shared new experiences, and our numbers of participants grew yet again. Topics covered included the roles of tributaries, influences on growth rates, recruitment, dispersal and migration, genetics, spawning, habitat, innovative conservation, restoration and management, habitat, and even beer and salmon, to name just a few.

Anadromous salmonids are an interesting system for examining dispersal, in part because of their well-known philopatric behaviour, but also because of the conservation challenges related to the dispersal of hatchery-origin fish. Building on earlier work, we provide an updated systematic review of dispersal and gene flow in anadromous salmonids. In particular, we compared studies on the dispersal of anadromous salmonids from wild and hatchery origins, including studies providing estimates of dispersal rates, observations of dispersal and results from modelling studies. We reviewed 228 studies and found these were unevenly distributed among species, with Atlantic salmon, Chinook salmon and sea trout being well-represented. Our results showcase considerable variability in estimated dispersal rates within and across studies, which is likely related to the different methodologies, dispersal propensities across species and populations, and spatial extents considered. Overall, our results confirmed a higher tendency of hatchery fish to disperse relative to wild fish, but we also found some variation across species that warrants further study. Moreover, we found that dispersal propensity tended to decline exponentially with distance and that the drivers of dispersal varied considerably among studies. Additionally, we highlight various facets of dispersal captured across this suite of studies, including variation in terminology, methods and metrics for characterising dispersal, and the spatio-temporal scales considered. Finally, our review revealed that few studies considered, and even fewer assessed, the implications of dispersal for the conservation and management of anadromous salmonids.</p>","PeriodicalId":11422,"journal":{"name":"Ecology of Freshwater Fish","volume":"33 4","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142555315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Quinn","doi":"10.1111/eff.12797","DOIUrl":"10.1111/eff.12797","url":null,"abstract":"&lt;p&gt;Anadromous salmonids of the genera &lt;i&gt;Oncorhynchus&lt;/i&gt;, &lt;i&gt;Salmo&lt;/i&gt; and &lt;i&gt;Salvelinus&lt;/i&gt; (hereafter, ‘salmon’), are culturally, economically and ecologically important fishes, affected by climate change at every life stage. Predictions about their future distribution and abundance are typically based on thresholds of thermal tolerance and changes to phenology in response to warming rivers, shifting flow regimes and complex marine processes (Crozier &amp; Siegel, &lt;span&gt;2023&lt;/span&gt;). Numerous conservation efforts focus on mitigating climate change, mainly in spawning and rearing habitats via restoration efforts to increase population resilience and capacity. While habitat alterations may dominate the narrative for salmon in a climate-altered future, indirect effects of climate change will likely be nuanced and in combination with other human activities. One such process involves the straying of natural- (‘wild’) and hatchery-origin salmon through climate-driven changes in olfactory imprinting and detection of olfactory signals, and trade-offs between homing and spawning habitat selection (Figure 1).&lt;/p&gt;&lt;p&gt;The great majority of surviving salmon return from the ocean to natal spawning grounds, guided by olfaction and other sensory inputs. Homing isolates spawning populations, favouring local adaptation (Dittman &amp; Quinn, &lt;span&gt;1996&lt;/span&gt;). Straying (spawning in non-natal sites) is also a natural phenomenon that may reflect a failure to locate the home river or a rejection of the natal site. While the terms homing and straying suggest binary alternatives, there are nuances. For example, straying can include fish spawning in a non-natal river, fish entering their natal river but spawning in a non-natal tributary, or hatchery-origin fish returning to their natal river and spawning there rather than entering their hatchery (Pollock et al., &lt;span&gt;2020&lt;/span&gt;). Whether a fish is considered to have strayed depends on the spatial scale of observation, with lower stray rates observed at larger geographic areas (e.g., basin) and higher stray rates at smaller areas of study (e.g., tributaries); this discrepancy is more pronounced in hatchery salmon that stray at higher rates at local scales (Pearsons &amp; O'Connor, &lt;span&gt;2024&lt;/span&gt;). Stray hatchery-origin salmon are especially problematic for fisheries managers attempting to limit genetic and ecological impacts on wild salmon (Keefer &amp; Caudill, &lt;span&gt;2014&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;Homing to natal rivers necessitates fish imprinting upon stream-specific chemical signals at one or more early life stages, retaining the memory without reinforcement while they feed in distant waters, and initiating upstream migration when they detect these signals in rivers as maturing adults. The sequential imprinting hypothesis (Keefer &amp; Caudill, &lt;span&gt;2014&lt;/span&gt;) posits that juvenile salmon learn a series of olfactory waypoints, beginning at the natal site as they migrate towards the sea, and then use these waypoints to ","PeriodicalId":11422,"journal":{"name":"Ecology of Freshwater Fish","volume":"33 4","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/eff.12797","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141646618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A classic example is embodied in the problem of introgression in hybridized fish populations, wherein management practices are generally unaware of any selective process at work, and therefore generally rely on numbers (adding or removing individuals) to reduce introgression. Such an example can be observed in the French Alps, where native Mediterranea (MED) brown trout have been highly introgressed through decades of stocking with domesticated Atlantic (ATL) brown trout. Recently however, new results shed light on a potential selective mechanism that may affect differentially the fitness of MED and ATL genes depending on the environment (GxE interaction). Using a demogenetic agent-based model able to account for such GxE interaction, we simulate a management scenario implemented in 2005 by some biodiversity managers and scientists, who attempted to restore the Mediterranea gene pool using translocation of near pure MED individuals in Atlantic-dominated areas. We show that the model is unable to recreate the observed introgression dynamics if the GxE interaction is not included. This finding implies that (i) eco-evolutionary mechanisms can have large effects on introgression dynamics on very short time scales and (ii) management of intraspecific diversity should increasingly rely on these natural mechanisms, so as to improve management targets and facilitate adaptation to rapid environmental changes.</p>","PeriodicalId":11422,"journal":{"name":"Ecology of Freshwater Fish","volume":"33 4","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141382992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines the responses of larvae of a resident species, the mandarin fish (<i>Siniperca chuatsi</i>), to environmental alterations caused by the Three Gorges Dam (TGD) in the middle reach of the Yangtze River. We hypothesized that larval abundance, feeding, growth, and survival would exhibit longitudinal recovery gradients, improving with the increased distance from the TGD. Our results confirm this hypothesis, showing that larvae further from the TGD exhibited higher abundance, increased feeding intensity, enhanced growth rates, improved survival rate, and earlier peak abundance and hatching dates. Key environmental factors, including water temperature and discharge, increased downstream, while transparency decreased. Major tributary inputs significantly contributed to these recovery gradients. The observed longitudinal gradients in larval attributes mirrored environmental changes, underscoring the TGD impact on population recruitment. These results highlight the broader implications of dam-induced changes on resident species recruitment, potentially affecting entire fish communities.

Females have more to lose with each hybrid fertilisation than males, so they should avoid it. Even if females choose con-specific males as preferred mates, they often cannot control which additional males release sperm during spawning. Polyandry is ubiquitous and may result in hetero-specific sperm competition between males of different species. In such cases, cryptic female choice (the ability to bias paternity towards certain males under sperm competition) is the last line of defence to prevent hybridisation of her eggs and is highly adaptive if it enables con-specific sperm preference. Such seems to be the case with the hybridisation of Atlantic salmon (<i>Salmo salar</i>) and brown trout (<i>S. trutta</i>) in their native Europe. Under hetero-specific sperm competition, hybrid fertilisations in these fish are reported to be reduced via ovarian fluid-mediated cryptic female choice. It is not known, however, whether the strength of this mechanism is dependent on reinforcement and thus, the historical sympatry/allopatry of hybridising populations. Brown trout are one of the world's worst invasive species. Ecological impacts arise through competition with other species (e.g. Galaxids in the southern hemisphere, <i>Oncorhynchus</i> in western North America). Eastern North America contains native salmonids that evolved in the absence of brown trout but have gametes that are compatible. The 140 -year-old brown trout invasion of Newfoundland is ground zero to study these potential interactions. Their relatively low spread rate across the island may be the result of inherent poor productivity, but data suggest it could also be a function of hybridisation with native Atlantic salmon and brook char (<i>Salvelinus fontinalis</i>).</p>","PeriodicalId":11422,"journal":{"name":"Ecology of Freshwater Fish","volume":"33 4","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141383502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Peak migration date occurred earlier in years with warmer spring air temperatures (a proxy for water temperatures), though this effect interacted with peak runoff timing. Both residence time and among-individual variation in migration timing were greater in years with larger spring discharge and later peak flows. Residence time was also longer in warmer years.
