Fisheries Cluster Insights Across India

The Department of Fisheries has envisaged a strategic focus on cluster development across key areas, including Pearl, Seaweed, Ornamental Fisheries, Reservoir Fisheries, Fishing Harbours, Saline Water Aquaculture, Cold Water Fisheries, Sea Cage Culture, Freshwater and Brackish-Water Fisheries, Deep Sea and Oceanic Fisheries, Organic Fisheries, Wetland Fisheries, Island Fisheries and other areas tailored to specific sectoral and regional needs. To advance this vision, the Department of Fisheries has already identified locations for three priority areas for development as such as Hazaribagh District in Jharkhand for pearl culture, Madurai District in Tamil for ornamental fisheries and UT of Lakshadweep for seaweed. Furthermore, the department has also notified Tuna Cluster in Andaman & Nicobar Islands. In line with above, the Department of Fisheries, MoFAH&D, GoI, has designated Soreng District in Sikkim as an Organic Cluster for development of fisheries and aquaculture in the State of Sikkim, marking a significant step in the development of the state’s fisheries and aquaculture sector. Government of Sikkim has already embraced organic farming, which has helped build a strong reputation for sustainable and eco-friendly agricultural practices. Introducing organic aquaculture will align with the state’s broader vision of promoting organic, sustainable, and environmentally friendly practices across all sectors

To be, or not to be, a non-native species in non-English languages: gauging terminological consensus amongst invasion biologists

In invasion biology, terminological frameworks contribute to the improvement of effective communication among scientists, stakeholders, and policy-makers. This is important not only for informing policy decisions but also for engaging the broader public in understanding the risks associated with biological invasions. Meanwhile, the role of non-English languages in advancing knowledge in invasion biology has gained momentum in recent years. Building on the seminal contributions in this scientific discipline by Professor Gordon H. Copp, this paper examines the provision of three key terms defining species invasiveness in 28 non-English languages. We first define the three non-redundant terms “non-native species”, “established species”, and “invasive species”. Through a comparative analysis of the equivalent of these terms in the 28 non-English languages, as contributed by our panel of invasion biologists and native speakers, with those in a reference review paper, and following the diffusion-of-English versus ecology-of-language paradigms, we identify discrepancies and nuances reflecting the dynamic nature of terminology in invasion biology. While some languages showed consensus in terminology, others differed due to either the avoidance of a culturally or politically laden term for “non-native” or the achievement of greater precision in meaning. Our findings highlight the requirement for clear and precise terminology in invasion biology and suggest the adoption of multidisciplinary approaches to reach consensus and facilitate communication amongst scientists, policy-makers, and the general public in a globally interconnected and rapidly changing world. This will enhance international collaboration and accelerate knowledge exchange, leading to more effective management of biological invasions

Climate Conflicts: What is the role of climate change in the India-Sri Lanka fisheries conflict?

For generations, the Palk Bay has been the lifeblood of both the Tamil and Sri Lankan fishing communities, supporting their livelihoods. But today, this once-thriving ecosystem is under threat. Driven by destructive practices like bottom trawling, 65 per cent of the commercially important varieties have been overfished in Tamil Nadu waters

Evaluating the effects of zinc oxide nanoparticles on a sentinel aquatic invertebrate species: Transcriptomic analysis and potential implications for ecosystem health

The widespread use of zinc oxide nanoparticles (ZnO NPs) in various products raises significant ecological concerns due to their potential toxic effects in aquatic environments. This study employed the Asian green mussel (Perna viridis) as a model to explore the molecular and ecological risks of ZnO NP exposure using transcriptomics. Mussels exposed to ZnO NPs (5, 10, and 15 mg/L) for 28 days showed significant gene expression changes in gill tissues, affecting immune response, calcium homeostasis, and cellular stress. Disrupted pathways such as FOXO, Wnt, and TGFβ reveal complex toxicity mechanisms. These findings provide crucial insights into the environmental impact of nanoparticle pollution, emphasizing the need for stringent regulations. Furthermore, the shared molecular pathways suggest that similar mechanisms may occur in humans, highlighting potential health risks associated with nanoparticle exposure

Otolith chemistry suggests population heterogeneity within a genetically homogeneous Indian scad population along Indian coast

The Indian scad, Decapterus russelli is one of the most exploited pelagic resources of India. Population genetic analyses using mitochondrial and nuclear markers indicated a lack of genetic structuring among populations from Indian waters. As this species is highly migratory, it is also important to establish the environmental influence on its population structure. In the present study, the whole sagittal otolith composition was analysed using Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) to assess spatial distribution of D. russelli collected from 4 sites along the Indian coast. Elemental ratios (Ba/Ca, Fe/Ca, K/Ca, Mg/Ca, Na/Ca, Sr/Ca and Zn/Ca) were analysed using univariate and multivariate statistics to determine whether this chemical signature can provide insight into the adaptive patterns. All element/Ca ratios are found to be significantly different between the four sampling locations (ANOVA, p < 0.05; MANOVA, p < 0.05). Five of the element/Ca ratios were found to be significantly different when the data was analysed coastwise (ANOVA, p < 0.05; MANOVA, p < 0.05). The LDA plot also showed the spatial heterogeneity of Element/Ca ratios between the four sampling sites, but some overlaps were also observed, reflecting the migratory ability of the species. This basic information on spatial ecology is required for formulating effective management and conservation strategies for the species

Anti-dyslipidemic potential of sulfated glycosaminoglycan from rock oyster Saccostrea cucullata: An in vivo study

The rock oyster, Saccostrea cucullata, native to the Indo-Pacific region, is widely recognized for its nutritional and therapeutic benefits. A sulfated glycosaminoglycan (SCP-2) with β-(1 → 3)-GlcNSp and α-(1 → 4)-GlcAp as recurring units was isolated from S. cucullata. SCP-2 exhibited substantial 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase (HMGCR) inhibition potential (IC50 0.65 mg/mL) in comparison with atorvastatin (IC50 0.72 mg/mL). An in vitro study of SCP-2 (0.1–160 μg/dL) revealed a 77–89 % reduction in triglyceride levels in Caco-2 cells after 4 days of incubation, similar to atorvastatin-treated cells (90 %). The efficacy of SCP-2 (at 90 mg/kg body weight) showed timely alleviation of triglyceride and cholesterol levels in tyloxapol-induced dyslipidemic rats (∼43 % and 81 % inhibition at 5 h), which was analogous to the atorvastatin treatment group (∼66 % and 71 %). Furthermore, SCP-2 (at 90 mg/kg body weight) showed mitigation in triglyceride (>50 %) and cholesterol levels (>25 %) in high-fat high-cholesterol (HFHC) diet-induced rats, similar to the lovastatin treatment group (approximately 62 % and 33 % inhibition on the 45th day). Histopathological studies of SCP-2 also showed recovery in ballooning degeneration, steatosis, and inflammation in liver tissues. Structure-activity relationship analysis suggested the importance of sulfate group in SCP-2 in contributing to its anti-dyslipidemic efficacy. The capability of SCP-2 to mitigate cholesterol, triglyceride, and HMGCR levels positions it as a promising functional food against dyslipidemia-related disorders

Minister inaugurates India’s Centre of Excellence for seaweeds

The centre was officially inaugurated recently by India’s Union Minister of State for Fisheries, Animal Husbandry & Dairying, Mr George Kurian. Emphasising the crucial role of ICAR-CMFRI in advancing marine fisheries and mariculture in the nation, the minister said that this new development will further contribute to the comprehensive growth of the fisheries sector. The minister also inaugurated the plantlet production unit for seaweed, followed by visit to the marine hatchery complex, national marine fish brood bank, recirculation aquaculture system (RAS), sea cage farm, and the green tiger shrimp hatchery
