Nanovaccines: Tiny Particles, Huge Protection

By: Ruhina Sheeba A , Manisha A.

Page No : 1-6

Abstract
Nanovaccines represent an innovative frontier in vaccine development, offering targeted, stable, and efficient antigen delivery systems through nanoscale carriers such as liposomes, polymers, and chitosan based particles. Unlike traditional vaccines, nanovaccines enhance both humoral and cellular immunity, require lower dosages, and provide controlled release with improved stability under variable storage conditions. In aquaculture, nanovaccines have emerged as sustainable alternatives to antibiotics and conventional vaccines, showing promising results in species like tilapia, carp, and shrimp by improving survival rates, disease resistance, and mucosal immunity. Recent advancements, including mucoadhesive formulations, dietary nano-supplements, and self-assembled nanostructures, highlight their growing potential to address disease challenges in fish farming. This review outlines the fundamental principles, structural components, applications, and future prospects of nanovaccines, with particular emphasis on their role in advancing aquatic animal health and promoting sustainable aquaculture.

Revolutionising Fish Health with AI-driven Disease Detection in Aquaculture

By: Justin Gladhys Jerlin Mol , Arumugam Uma

Page No : 7-12

Abstract
Aquaculture plays a crucial role in global food security, yet disease outbreaks remain one of the most significant challenges affecting fish health and farm productivity. Traditional disease monitoring methods rely heavily on manual observation, which is often time-consuming, error-prone, and ineffective for early detection. The integration of Artificial Intelligence (AI) into aquaculture health management offers transformative potential to overcome these limitations. AI-driven systems can analyse behavioural, visual, and environmental data in real time to identify subtle signs of disease or stress, enabling rapid and precise responses. Techniques such as image recognition, behavioural tracking through camera systems, and machine learning-based water quality monitoring have demonstrated promising results in predicting and mitigating disease outbreaks. Despite these advances, several barriers including the lack of standardised, high-quality datasets, data-sharing protocols, and concerns about data privacy and implementation costs continue to hinder large-scale adoption. Addressing these challenges through improved infrastructure, collaborative data frameworks, and ongoing algorithmic refinement will be key to unlocking the full potential of AI in aquaculture. Ultimately, the application of AI in disease detection can enhance fish welfare, reduce antibiotic usage, and ensure sustainable and profitable aquaculture practices.

Aquatic Xenobiotic: Biomarkers for Assessing and Mitigating Environmental Contamination

By: Sana K. M Patel , Indulkar S. T. , Ninawe A.S.

Page No : 34-52

Abstract:
The persistence of biologically active xenobiotic compounds in aquatic environments poses a significant threat to ecosystem health and human safety. This review synthesizes current knowledge on the interactions and ecological impacts of xenobiotics in aquatic systems, with a focus on fish as sensitive bioindicators. Xenobiotics, including heavy metals and synthetic chemicals, induce a spectrum of biological responses in fish, ranging from synergistic or antagonistic effects to alterations in mortality, behaviour, physiology, and cellular integrity. Notably, bioaccumulation of these contaminants in fish tissues not only disrupts aquatic biodiversity but also enters the human food chain, raising public health concerns.

Recent research highlights the role of cellular-level xenobiotic modifications in carcinogenicity and other chronic effects. To address these challenges, freshwater fish species are increasingly employed as ecological sentinels for early contamination detection. Furthermore, this review explores innovative remediation strategies, such as bacterial bioremediation and phytoremediation, which leverage natural processes to degrade xenobiotics. Advances in understanding xenobiotic biotransformation pathways offer promising avenues for mitigating environmental pollution and safeguarding aquatic ecosystems.

Comparative Evaluation of a Phytogenic Feed Additive, for Maintenance of Water Quality Standards in Aqua Ponds

By: Bhagwat V.G. , Varun Kumar K. , Devojit Das

Page No : 53-61

Abstract
The present field investigation was carried out to evaluate the effectiveness of a proprietary Phytogenic Feed Additive (PFA) in maintaining pond water quality parameters in aquaculture systems, in comparison with two commercially available competitor products. Eight farmer-managed shrimp culture ponds were selected and allocated into three supplementation groups: G1- PFA (n = 6), G2- Competitor 1 (n = 1), and G3- Competitor 2 (n=1). The PFA was applied at a recommended dose of 15-20 kg/ha during pond preparation, followed by 10-15 kg/ha once every 7-10 days in low-salinity ponds and 8-10 kg/ ha once every 10-15 days in high-salinity ponds during the culture period. Competitor products were applied according to manufacturers’ recommended protocols. Key water quality parameters, mineral concentrations, and ionic profiles of pond water were assessed before and 24 h after product application. Ponds supplemented with PFA demonstrated consistent numerical improvements in water quality, mineral availability, and ionic balance, while all parameters remained within established reference ranges. Overall, pond environmental stability was superior in the PFA-supplemented ponds compared with competitor products. These findings indicate that PFA is effective in supporting optimal pond water quality and mineral equilibrium and may be recommended as a phytogenic feed supplement for sustainable aquaculture water management.

Selective Breeding Program in Ornamental Fishes with Special Emphasis on Guppy

By: Judith Betsy C. , Vinisha, M.S. , Smriti S.

Page No : 62-69

Abstract
The ornamental fish industry is a rapidly expanding segment of global aquaculture, in which the guppy (Poecilia reticulata) holds a prominent commercial position owing to its exceptional phenotypic diversity, short generation time, and ease of captive breeding. This review consolidates current knowledge on selective breeding strategies in guppies, with particular focus on the genetic basis of ornamental traits. Quantitative genetic investigations have consistently demonstrated moderate to high heritability for key characteristics such as colour patterns, pigmentation intensity, and fin morphology, underscoring the effectiveness of structured selection programmes. The wide array of colour phenotypes observed in domesticated guppy strains is governed by genes involved in chromatophore development, melanin synthesis, and carotenoid uptake and metabolism. Recent advances in molecular genetics and genomics have facilitated the application of marker-assisted and genomic selection, enabling more accurate and accelerated genetic improvement. The integration of traditional selective breeding with modern genomic approaches has strengthened the role of the guppy not only as a cornerstone species in ornamental aquaculture but also as a valuable model organism for investigating sex-linked inheritance and evolutionary genetics. Insights gained from guppy breeding programmes have broader relevance for the sustainable genetic improvement of other ornamental fish species.

Exotic Fish Species Introduction in India: Benefits, Risks, and Regulatory Needs

By: Sweety Singh , Judith Betsy C.

Page No : 70-91

Abstract
India possesses one of the richest aquatic biodiversity resources in the world, yet the increasing introduction of exotic aquatic species for aquaculture, ornamental trade, biological control, and inland water management has significantly altered native ecosystems. While several introductions, such as Cyprinus carpio, Ctenopharyngodon idella, Hypophthalmichthys nobilis, and Oreochromis niloticus, have substantially enhanced fish production, food security, and rural livelihoods, their ecological consequences remain a major concern. Exotic species contribute significantly to global aquaculture output and economic growth; however, they may also cause competition with native species, habitat alteration, genetic introgression, disease transmission, trophic disruptions, and biodiversity loss. Cases of invasive expansion, stunting, turbidity enhancement, and the spread of pathogens such as White Spot Syndrome Virus highlight the ecological risks associated with unregulated introductions. This review synthesises the historical background, purposes, benefits, and ecological consequences of exotic fish introductions in India, and emphasises the need for strict quarantine protocols, ecological risk assessment, policy strengthening, and prioritising the development of indigenous species. A balanced and science-based regulatory framework is essential to harmonize aquaculture expansion with long-term ecosystem sustainability and biodiversity conservation.

Robotic Fish: Biomimetic Underwater Vehicles for Aquaculture Management and Environmental Monitoring

By: J. Nowshmi John , P. Ruby

Page No : 92-106

Abstract
Robotic fish are biomimetic underwater vehicles designed to replicate the swimming behaviour of fishes. Over the past decade, advances in soft robotics, sensing technologies, and autonomous control have expanded their potential applications in aquaculture and environmental monitoring. Compared with conventional underwater vehicles, robotic fish can operate with reduced noise and hydrodynamic disturbance, making them suitable for use in sensitive aquatic environments.

This review examines recent developments in robotic fish design, including body-and-caudal-fin and median-and-paired-fin propulsion systems, actuation technologies, structural materials, sensor integration, and autonomous control strategies. Particular attention is given to applications in water quality monitoring, environmental mapping, pollution assessment, aquaculture inspection, and fish behaviour assessment. Studies investigating interactions between robotic fish and live fish are also reviewed to evaluate their implications for animal welfare and behavioural management.

The review further discusses key operational challenges, including limited battery endurance, biofouling, navigation in complex environments, and deployment costs. Emerging solutions and future research priorities are highlighted, with emphasis on improving long-term autonomy, sensing capability, ecological compatibility, and field reliability. Overall, robotic fish are evolving from experimental biomimetic platforms into increasingly practical tools for supporting sustainable aquaculture, fisheries management, and aquatic ecosystem monitoring.
