Environmental influences on life history strategies in partially anadromous brown trout (Salmo trutta, Salmonidae)

et al. 2019

This paper reviews the life history of brown trout and factors influencing decisions to migrate. Decisions that maximize fitness appear dependent on size at age. In partly anadromous populations, individuals that attain maturity at the parr stage typically become freshwater resident. For individual fish, the life history is not genetically fixed and can be modified by the previous growth history and energetic state in early life. This phenotypic plasticity may be influenced by epigenetic modifications of the genome. Thus, factors influencing survival and growth determine life‐history decisions. These are intra‐ and interspecific competition, feeding and shelter opportunities in freshwater and salt water, temperature in alternative habitats and flow conditions in running water. Male trout exhibit alternative mating strategies and can spawn as a subordinate sneaker or a dominant competitor. Females do not exhibit alternative mating behaviour. The relationship between growth, size and reproductive success differs between sexes in that females exhibit a higher tendency to migrate than males. Southern populations are sensitive to global warming. In addition, fisheries, aquaculture with increased spreading of salmon lice, introduction of new species, weirs and river regulation, poor water quality and coastal developments all threaten trout populations. The paper summarizes life‐history data from six populations across Europe and ends by presenting new research questions and directions for future research.

“…The TWW appears to be highly polluted with a plethora of contaminants, including metals and polycyclic aromatic hydrocarbons (PAHs) (Meland et al, 2010a), in concentrations that can be orders of magnitude higher than concentrations measured in ordinary road runoff (Amundsen and Roseth, 2004;Andersen and Vethe, 1994;Barbosa et al, 2007;Meland, 2010). Several contaminants (e.g.…”

In vivo and in vitro effects of tunnel wash water and traffic related contaminants on aquatic organisms

In order to maintain the construction and safety of road tunnels, they are routinely washed. The wash water appears to be highly polluted with a plethora of contaminants in elevated concentrations. In addition, new and emerging compounds are likely to occur. The discharge water has shown acute toxic and sub-lethal effects in several organisms. In this study, ecotoxicity tests with algae (Pseudokirchneriella subcapitata) and in vitro tests with primary rainbow trout (Oncorhynchus mykiss) hepatocytes were used to characterize the effect of TWW from three different tunnels. In addition, selected N- and Cl-PAHs were tested for cytotoxicity, EROD activity and CYP1A protein production. TWW samples and/or extracts from two tunnels reduced the algal growth and induced cytotoxicity, EROD activity and CYP1A protein production in vitro. Four of the eight tested Cl- and N-substituted PAHs induced EROD activity and CYP1A protein production at micro-molar concentrations. N-PAHs were detected in samples from the tunnel wash, highlighting substituted PAHs as potentially important traffic-related contaminants.

REVISIÓN Efectos del piojo del salmón Lepeophtheirus salmonis(Copepoda: Caligidae) en las poblaciones de truchas (Salmo trutta) de la costa NE Atlántica Abstract.-Salmon lice are external parasites on salmonids in the marine environment. During recent years, s ea lice abundance has been increased due to the presence of salmon farming using on-growing floating seas-cages. Amongst salmonids, sea trout is especially vulnerable to salmon lice infestations, because during their mari ne residence they typically remain in coastal waters, where open net cage Atlantic salmon farms typically are situated. In this report the existing knowledge about the effects of salmon lice on sea trout populations in the NE Atlantic coastal waters has been reviewed, assessing the current situation of this problematic. Salmon aquaculture increase the salmon lice abundance, which affect negatively on sea trout populations as an increase in marine mortality, changes in migratory behaviour and reduction of marine growth. These conclusions are based on published studies that range from those investigating the effects of salmon lice on individual fish, both in the laboratory and the field, to analyses of their impacts on populations in the wild. In sum, the combined knowledge from the reviewed studies provides evidence of a general and pervasive negative effect of salmon lice on sea trout populations, especially in intensively farmed areas. The effects induced by elevated salmon lice levels inevitably imply a reduction in numbers and body size of sea trout returning to freshwater for spawning, affecting the local population dynamic and recreational and commercial fisheries in the most impacted areas. Key words: Parasites, aquaculture, impact, salmonids, managementResumen.-Los piojos del salmón son parásitos externos de salmónidos en ambientes marinos. En los últimos a ños, la abundancia de este parásito ha aumentado debido a la presencia de cultivos de salmones en jaulas de engorde en mar abierto. Entre los salmónidos, la trucha es especialmente vulnerable a las infecciones por el piojo ya que permanece en aguas costeras durante su período marino, donde se sitúan las instalaciones acuícolas de cultivo del salmón. En el presente trabajo se recopila la información existente sobre los efectos del piojo del salmón en las poblaciones de truchas silvestres que habitan las costas del NE Atlántico, y evaluar posteriormente el estado actual de dicha problemá tica. La acuicultura de salmón aumenta la abundancia de piojos, los cuales impactan negativamente sobre las poblaciones d e truchas, aumentando la mortalidad, cambiando las pautas migratorias y disminuyendo el crecimiento. Estas conclusiones se basan en estudios científicos que abarcan desde experimentos en el laboratorio o en el campo de los efectos del piojo en las truchas a nivel individual, hasta estudios poblacionales de dichos impactos. En resumen, el conocimiento adquirido en esta revisión evidencia la existencia de un efecto general y persuasivo de los piojos en las pobl aciones de truchas...
