Special Issue Information

Dear Colleagues,

The combined effect of climate change and alien species invasions on native biodiversity is a topical issue. Especially in freshwater ecosystems, where climate models predict increasing water temperatures, the synergistic effect between global changes and biological invasions can represent a major driver of native fish species decline. Although their negative impacts have been the subject of several studies, these anthropogenic pressures are often treated independently, overlooking their interactions. The analysis of the potential interactive effects between biological invasion, thermal, stress and conservation status of native fish species can form the basis for developing appropriate recovery actions for the most vulnerable species and for implementing proper mitigation measures. The aim of this Special Issue is to collect papers (original articles, mini reviews) focused on testing the interactive effects of climate change, invasive species, and native freshwater fish. Original studies based on long-term fish and environmental data series are welcome.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Fishes is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Elevated Carbon Dioxide and Its Impact on Growth, Blood Properties, and Vertebral Column of Freshwater Fish Mahseer, Tor tambroides Juveniles

Abstract

The level of carbon dioxide, which resembles water acidification, is critical to the success of juvenile fish production. The growth, skeletal deformities, and blood parameters of the economically important freshwater fish mahseer, Tor tambroides, were assessed in different concentrations of pCO₂ (400, 700, and 1000 µatm pCO₂). The highest growth properties (survival rate, body weight gain (BWG), specific growth rate (SGR)) in mahseer were observed at 400 µatm, whereas the lowest growth indices were found in the treatment of 1000 µatm pCO₂. The lowest pCO₂ concentration was found to be within the optimum healthy blood parameter range. The fish exposed to acidic conditions (700 and 1000 µatm) exhibited considerably higher levels of haemoglobin and haematocrit compared to the control fish. Glucose levels were significantly lower in the acidic conditions, while total cholesterol levels in mahseer fish exposed to acidic conditions were higher. The fish displayed skeleton malformations as the concentration of pCO₂ was elevated. The findings from this research could be set as a standard technique in the juvenile rearing of mahseer fish under acidified conditions. Full article

Synergistic Effects of Climate Change and Alien Fish Invasions in Freshwater Ecosystems: A Review

by Antonella Carosi, Francesca Lorenzoni and Massimo Lorenzoni

Fishes 2023, 8(10), 486; https://doi.org/10.3390/fishes8100486 - 28 Sep 2023

Abstract

The interaction between climate warming and alien fish invasions could have severe consequences in inland waters, which represent isolated environments with high biodiversity richness. Due to the current climatic trend, increasing water temperatures and salinization, shorter ice cover period, and altered flow regimes are predicted for these environments. The aim of this review is to offer a comprehensive analysis at a global scale of the recent studies available in the literature, focused on the responses of invasive freshwater fish to the effects of climate change in both lotic and lentic environments. To achieve this purpose, we selected 34 relevant papers, using the Scopus and Google Scholar database. New alien species establishment, distribution range expansion of species already introduced, and exacerbating impacts on freshwater ecosystems and the native fish communities they host were included in the topics covered by the analyzed papers. Despite the uncertainties related to the unpredictability with which the effects of global warming will occur, the findings of the selected studies served as a support to evaluate conservation and management implications, with particular reference to possible mitigation strategies.
