Therapeutic evaluation of papaya (Carica papaya) leaf extract for disease management in Indian major carp, Labeo rohita infected with Aeromonas veronii - Aquaculture Science and Management

Background The emergence of antibiotic-resistant pathogens in aquaculture necessitates the exploration of sustainable alternatives for disease management. This study investigates the antibacterial and therapeutic efficacy of dietary administered Carica papaya leaf extract (PLE) against Aeromonas veronii in Labeo rohita, a key species in Indian freshwater aquaculture. Results Among aqueous, ethanolic, and methanolic extracts of papaya leaf, only the methanolic extract exhibited significant in vitro antibacterial activity, with a minimum inhibitory concentration (MIC) of 12.5 mg mL⁻¹ for A. veronii. Acute toxicity assessment revealed median lethal concentration (LC₅₀) value of 160.69 mg L⁻¹ for PLE in L. rohita. The median lethal dose (LD₅₀) for A. veronii was determined as 1.4 × 10⁴ CFU (Colony-Forming Units) mL⁻¹. In an in vivo trial, fish were administered PLE-supplemented diets at concentrations of 25, 50, 75, and 100 mg g⁻¹, at a feeding rate of 2% of body weight per day, following infection. Hematological and immune-biochemical parameters, including total erythrocyte count, hemoglobin, total leucocyte count, C-reactive protein, protein, albumin, globulin, liver enzymes (serum glutamic-oxaloacetic transaminase - sGOT, serum glutamic pyruvic transaminase – sGPT and alkaline phosphatase - ALP), and catalase activity, were evaluated. Results showed significant recovery in PLE-fed groups, particularly at lower doses of 50 mg g−1, indicating improved immune response, reduced oxidative stress, and restored liver function. Conclusion The findings suggest that methanolic PLE is a promising phytotherapeutic agent for managing A. veronii infections, supporting its use in aquaculture disease management.

Springer Nature Collections are curated groups of articles within a journal that provide highly focused exploration of specific themes and emerging topics to enhance the visibility and impact of research. By contributing to a Collection, you can benefit from increased visibility, meaningful academic connections, and ⁠broader impact. This collection - from the journal Aquaculture Science and  Management - focuses on the aquatic pathogen Aeromonas hydrophila.

Aeromonas hydrophila is a pathogen affecting a wide range of aquatic species, leading to severe economic losses and posing challenges to food security. Understanding the mechanisms by which Aeromonas hydrophila induces inflammation, alters intestinal morphology, and triggers antioxidant responses is essential for developing effective management strategies. As aquaculture continues to expand globally, the need for sustainable practices is urgent. The "Impact of Aeromonas hydrophila on Aquaculture: Inflammation, Intestinal Changes and Antioxidant Responses" collection in Aquaculture Science and Management focuses on this issue and invites contributions to the field.  Topics of interest include but are not limited to:

- Mechanisms of inflammation in fish
- Intestinal morphology alterations
- Histopathological studies of Aeromonas infections
- Antioxidant responses in aquaculture species
- Disease management strategies
- Genetic resistance to Aeromonas hydrophila 
- Environmental factors influencing disease outbreaks
- Impacts on aquaculture sustainability

Impact of Aeromonas hydrophila on Aquaculture: Inflammation, Intestinal Changes and Antioxidant Responses” is led by Shivendra Kumar, Dr. Rajendra Prasad Central Agricultural University and Izzet Burçin Satıcıoğlu, Bursa Uludag University. The collection accepts original research, reviews and methodologies. As a new open access journal, we are able to cover the article processing charges for publications.

Synergizing aquaculture & blue carbon in a changing climate

Aquaculture Science and Management calls for contributions to a Collection centred on "Synergising aquaculture & blue carbon in a changing climate." We invite researchers to share original studies that investigate the intersection of aquaculture practices and blue carbon sequestration in coastal ecosystems. This Collection aims to elucidate how aquaculture can contribute to climate mitigation strategies, including the enhancement of carbon storage and the restoration of coastal habitats.

Topics of interest include but are not limited to:

  • Carbon sequestration mechanisms in aquaculture
  • Coastal ecosystem restoration practices
  • Aquaculture systems and their climate resilience
  • Integration of blue carbon strategies in fisheries
  • Socioeconomic impacts of restorative aquaculture
  • Policy frameworks for synergies in aquaculture and blue carbon
  • Technological innovations in sustainable aquaculture practices

Join us in fostering interdisciplinary dialogues that highlight the critical role of aquaculture in the sustainability of our marine environments.

This Collection supports and amplifies research related to SDG 13, Climate Action and SDG 14, Life Under Water.

All submissions in this Collection undergo the journal’s standard peer review process. Similarly, all manuscripts authored by a Guest Editor(s) will be handled by the Editor-in-Chief. As a newly launched open access publication, this journal has waivers to cover article-processing charges (APCs). For more information about receiving a waiver, please contact alex.waite@springernature.com before submitting a manuscript. For additional support please visit OA funding and support, or email OAfundingpolicy@springernature.com or the Editor-in-Chief.
