PREAMBLE
                                                                                                                                                                                                                                                                            

Water is fundamental to life on Earth, and oceans covering more than 70% of the planet’s surface play a crucial role in sustaining biodiversity, regulating climate systems, and supporting livelihoods and food security. Marine and coastal ecosystems are vital for environmental balance, economic stability, and human well-being. However, increasing challenges such as marine pollution, overfishing, and habitat degradation pose serious threats to the health and productivity of aquatic ecosystems. There is an urgent need to conserve and sustainably use oceans, seas, and marine resources for the benefit of future generations.

Nitte (Deemed to be University) is committed to advancing these objectives through academic engagement, capacity building, outreach and awareness programmes, and responsible institutional practices. During the reporting year, the University actively contributed through structured PREAMBLE academic activities, national and state-level collaborations, memoranda of understanding, and outreach initiatives focusing on marine biodiversity, overfishing, plastic pollution, microplastics, and coastal ecosystem conservation. In addition, the University strengthened its research efforts through focused studies on sustainable aquaculture health management, antimicrobial resistance and food safety in aquatic systems, microplastics and emerging marine contaminants, and the conservation and sustainable utilisation of marine biodiversity and bioresources. The University also demonstrates a strong commitment to responsible



institutional practices that support sustainable water management and aquatic ecosystem protection. These include water-sensitive waste disposal systems, periodic water quality monitoring, recycling and reuse of treated wastewater, rainwater harvesting, stormwater management, and the use of non-potable water for appropriate purposes across the campus. Nitte (Deemed to be University) continues to promote the sustainable use of aquatic resources while engaging students, stakeholders, and the wider community in protecting life below water.

HIGHLIGHTS OF RESEARCH ACTIVITIES

Oral Nanovaccines for Aquaculture Disease Control
PLGA nanoparticle–based oral vaccines were developed for targeting Aeromonas hydrophila and Edwardsiella tarda. Recombinant outer membrane proteins (Omp23, OmpA, OmpS2) were expressed, encapsulated, and delivered through feed to enhance mucosal immunity. Characterization confirmed optimal particle size and sustained antigen release. Vaccination trials in Rohu and zebrafish demonstrated enhanced innate immune responses and improved survival following pathogen challenge. The approach offers a scalable, non-invasive alternative to antibiotics in aquaculture.

Antimicrobial Resistance & Molecular Epidemiology
Studies investigated Streptococcus agalactiae in aquatic environments, focusing on virulence profiling, capsular serotyping, antimicrobial susceptibility, and CRISPR-Cas characterization. Molecular diagnostics revealed key virulence genes and emerging resistance to aminoglycosides and β-lactams. CRISPR spacer analysis provided insights into strain evolution and phage exposure. These findings strengthen genomic surveillance frameworks, improve pathogen detection accuracy, and support antimicrobial stewardship strategies in aquaculture and public health contexts.

Marine Bioactives for Therapeutic Applications
Macroalgae-derived bioactive compounds were explored for antioxidant and anticancer potential using zebrafish models and biochemical assays. Extracts from green and brown seaweeds demonstrated significant radical scavenging, lipid peroxidation inhibition, anti-angiogenic, and antiproliferative effects. Solventdependent extraction influenced phenolic and flavonoid content, correlating with biological activity. The research highlights marine algae as promising sources of nutraceutical and pharmaceutical compounds for oxidative stress–related disorders and cancer therapy development.

Marine Biotechnology for Sustainable Materials & Bioremediation
Research in this area advances marine-derived functional materials and environmental solutions. Fish collagen hydrogels and gelatinbased food applications demonstrate sustainable valorization of fish by-products for biomedical and food systems. Parallel studies evaluate microbial degradation of microplastics and marine fuel oil, along with biocontrol strategies for harmful algal blooms. Together, these efforts promote circular bioeconomy principles, eco-friendly remediation technologies, and sustainable utilization of marine resources.

Empowering officials with tools to monitor and mitigate microplastic contamination.
NUCSER organized a six-day intensive training program on Microplastic Quantification and Characterization from 15th to 20th December 2025 for five officials from the Directorate of Environment and Climate Change, Govt. of Manipur, Imphal. The program aimed to enhance technical capacity in monitoring microplastic pollution and understanding its environmental impact. Combining theory with hands-on practice, the training covered sampling and analysis of microplastics in water, soil, air, and food. Sessions were conducted by Dr. Gunimala Chakraborty and Dr. Rajeshwari Vittal. Participants learned field sampling techniques for water and sand, followed by laboratory procedures such as digestion, staining, and identification of microplastics. Advanced analytical methods, including FTIR spectroscopy and fluorescence microscopy, were introduced for detailed characterization. A visit to One Earth Lab, Baikampady, provided exposure to atmospheric sampling systems, highlighting pathways of microplastic contamination across ecosystems.

Monitoring the health of aquatic ecosystems

Lake Adoption, Rejuvenation, Ranching and Monitoring the Health of Inoli Lake
Lake rejuvenation activities at Inoli Lake, including cleaning and awareness programmes (09/09/2025) and scientific lake ranching (11/10/2025), contributed to improved ecological health, aquatic biodiversity, and ecosystem resilience. Periodic water quality monitoring conducted between August and December 2025 (sampling on 04/11/2025) assessed key physicochemical and biological parameters, indicating nutrient enrichment and microbial contamination that required management interventions. Major challenges such as weed infestation, eutrophication, and declining biodiversity were addressed through manual and mechanical weed removal, native fish stocking, and habitat improvement measures. Adoption of the lake by NitteDU, along with community participation via the Gram Panchayath, enabled regular monitoring, maintenance, and protection of the aquatic system
