Special Issue Information

Dear Colleagues,

The fish are the most diverse group of vertebrates on Earth, with more than 34,000 species living in freshwater, saltwater, and the deep ocean, and they are critical to global ecosystems and food supply. They encompass various physiological and ecological adaptations in response to various habitat environments. In order to adapt to the complex and changing living environment, fish have evolved a variety of functional traits, including external morphology, reproductive ability, trophic level,  growth rate, reproductive characteristics, metabolic efficiency, etc., which has been considered as a key factor reflecting the ecological adaptation potential of species. Moreover, the gut microbiome has been recognized as a vital "microbial trait" of fish and is closely related to many characteristics of its host. Thus, it is necessary to deliver valuable insights into behavioral ecology, eco-physiology, population dynamics, and genetics, as well as the monitoring of ecosystems in exploring fish response to rapid environmental change, which provides effective information for fish conservation and ecosystem health. This Special Issue aims to showcase the adaptation and response of freshwater fish to environmental changes.  We invite researchers, scientists, and practitioners to submit original research articles and reviews that address, but which are not limited to, the following topics:

  • Fish  population and community;
  • Fish habitat;
  • Fish eco-physiology;
  • Fish behavior monitoring;
  • Fish conservation biology;
  • Gut microbiome and its insight into differences in fish physiology and behavior;
  • Ecological adaptation of fish to human disturbance (e.g., hydroelectric development);
  • Responses of fish communities to climate change.

We encourage contributions from interdisciplinary research teams, encompassing fisheries scientists, ecologists, biologists, and policymakers, to provide a comprehensive overview of the field.

The Qinghai–Tibet Plateau (QTP) is a unique ecological area that has faced issues like diminishing ecosystem stability and increasing pressures on resources and the environment. These issues have arisen as a result of the combined impact of global warming and human activities in recent times. The study of the growth and distribution patterns of schizothoracinae fishes can support guiding policy decisions about the conservation of aquatic species and ecological habitats in the QTP. The investigation on fish resources was carried out in the QTP section of the Nujiang River during the spring and autumn seasons of 2017, 2018, and 2019. A total of seven sampling sites were established based on variations in elevation. According to length–weight relationship (LWR) analysis, Schizothorax nukiangensis mainly displayed a negative allometric growth while Ptychobarbus kaznakovi and Schizopygopsis thermalis mainly showed near isometric growth or positive allometric growth in the QTP section of the Nujiang River. Due to temperature and food abundance, the three schizothoracinae fishes showed better growth performance in autumn than spring. Spatial heterogeneity exhibited a greater influence on the LWR of S. nukiangensis and P. kaznakovi than seasonal variation. In contrast, seasonal variation on S. thermalis showed greater influence than spatial heterogeneity. According to the linear mixed effect model (LMM), both spatial factors and seasons had influence on fish growth in the QTP. Schizothorax nukiangensis was identified as the predominant species from CWL to BS, spanning an altitude range of 1800 to 2700 m. Ptychobarbus kaznakovi was identified as the main species at LL, BB, and BR, occupying an altitude range of 2700 to 3800 m. Schizopygopsis thermalis is primarily distributed at altitudes beyond 4000 m and along the tributary river Yuqu. Principal coordinates analysis (PCOA) and nonmetric multidimensional scaling (NMDS) divided schizothoracinae fish populations into three clusters by spatial differences. Redundancy analysis (RDA) and Monte Carlo Permutation analysis revealed that habitat elevation and water temperature had a significant impact on schizothoracinae fish distribution. This article enhances our understanding of the distribution and environmental adaptation of indigenous fish in the Qinghai–Tibet Plateau. Full article
