Special Issue Information

Dear Colleagues,

This Special Issue aims to collect full-length articles, review articles, and communications that present original research on the latest strategies in fish stress (Stressors, stress responses, and their impacts, etc.). The compilation will cover a range of topics, including but not limited to, the effects of different additives on stress response in fish, the impact of stressors on fish health, and the endocrine and physiological responses of fish under the action of additives, management of stress response in fish farming, the regulatory effect of feed additives on endocrine/physiological responses.

This Special Issue invites contributions addressing various aspects related to the stress response. Furthermore, while the focus is primarily on fish, submissions on stress responses in other aquatic species will also be considered, valuable works on other aquatic species can also be considered.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Herbal feed additives have benefits in aquaculture, as they can improve growth performance, welfare, and stress resistance. Hence, the effects of dietary Prosopis farcta extract (PFE) on the growth parameters, digestive enzyme activity, antioxidant defense, innate immunity responses, and resistance to ammonia stress in the common carp, Cyprinus carpio, were studied. Fish (15.14 ± 0.72 g) were fed on diets without the PFE (PFE0) or those fortified with 0.5% (PFE0.5), 1% (PFE1), or 2% (PFE2) PFE for 60 days and then subjected to ammonia stress for 24 h. The growth rate, feed efficiency, and amylase-, lipase-, and protease-specific activities in the PFE1 and PFE2 treatments showed significant elevations compared to these values in PFE0. The intestinal protease-specific activity significantly increased in all of the PFE treatments compared to that in the PFE0 treatment. Serum total protein and immunoglobulin significantly increased in the PFE1 treatment, whereas serum albumin and alternative complement activity significantly increased in the PFE2 treatment compared to these values in the PFE0 treatment. The PFE2 treatment significantly mitigated post-stress elevations in serum cortisol, glucose, malondialdehyde levels, alanine aminotransferase, and aspartate aminotransferase activities. The PFE1 treatment significantly mitigated post-stress elevations in CAT activity and decreases in SOD and lysozyme activity. In conclusion, 1–2% dietary PFE supplementation can improve the growth performance, health, and resilience to environmental stressors of the common carp. Full article
