Assessing the Role of Fish Farming in Poverty Alleviation through a Socio-Economic and Factor Analytical Study in Chhattisgarh, India
Fish culture is a fast-expanding livelihood activity in India, playing a key role in income, jobs, and food security. Chhattisgarh has great promise for inland aquaculture, though its poverty-reduction effect is limited by socio-economic inequalities, institutional factors, and infrastructural constraints. The current research sought to analyze the socio-economic and demographic characteristics of fish farmers in the selected Chhattisgarh districts and determine most significant factors affecting their livelihood through factor analysis. The survey covered 243 respondents such as fish farmers, traders, consumers, policymakers, and researchers using a structured five-point Likert scale questionnaire. Descriptive statistics collapsed demographic and occupational data, while Exploratory Factor Analysis (EFA) applying Principal Component Analysis and Varimax rotation derived latent factors driving poverty-reduction outcomes.
Findings revealed that the majority of participants were young (25–34 years), male (64.6 %), and rural-dwelling (53.1 %) with mixed educational and professional backgrounds. Descriptive statistics revealed moderate consensus on the significance of government policies, access to technology, market linkages, and climate considerations to improve livelihoods. Factor analysis revealed two major components accounting for 59.3 % variance: (i) Economic Empowerment and Sustainable Livelihoods, and (ii) Institutional and Environmental Support Systems. The research concludes that aquaculture improves substantially the diversification of income, employment, and household resilience. Inclusive institutional support, training, access to technology, and climate-resilient culture are requirements. Capacity development, policy interventions, and public–private partnerships are suggested to enhance sustainable, inclusive, and equitable aquaculture-led poverty reduction

Utilization of Shrimp Shell Waste for Nutritional Enhancement of Edible Oils: A Case Study Using Sunflower Oil
Shrimp shell waste, a major by-product of India’s seafood industry, presents both an environmental challenge and a valuable opportunity for sustainable resource utilization. This study explores the nutritional fortification of sunflower oil through thermal extraction of bioactive compounds from shrimp shell waste. A simple boiling process facilitated the migration of protein and essential minerals; potassium, calcium, sodium and zinc into the oil phase, resulting in a measurable enhancement of its nutritional profile. Protein content increased from 0 to 0.06%, while mineral concentrations also showed significant enrichment. Comparative analysis with existing literature confirmed the nutrient density of shrimp shell byproducts, including their high ash content and balanced amino acid composition. The findings underscore the potential of shrimp shell waste as a functional ingredient for food, feed and nutraceutical applications, while promoting circular economy principles and waste utilisation in seafood processing

A Comprehensive Overview on the Biology and Culture Practices of Mud Crab (Scylla Sp.) in India
The genus Scylla, commonly known as mud crabs, is frequently found in mangrove habitats, brackish waters, coastal regions, ponds, and intertidal swamps, making them a rapidly growing exportable resource in India. Farming mud crabs serves as a vital income stream for fish farmers throughout the country. The increasing demand for mud crabs in the export market as an alternative to shrimp has led to heightened collection of wild seeds for cultivation, thereby posing a threat to natural populations. To promote sustainable crab farming and alleviate pressure on wild stocks, it is essential to focus on the availability of seeds, which is a crucial factor for successful farming. Additionally, crab fattening proves to be lucrative due to its quick turnover and high survival rates. This practice is particularly advantageous for small-scale operations, providing an extra source of income for local fishermen. This review article aims to consolidate existing knowledge on the ecology and biology of mud crabs
Molecular Characterization and Prevalence of Intestinal Parasites in Oreochromis niloticus (Nile Tilapia) from Ureje Reservoir, Ado-Ekiti, Nigeria
Oreochromis niloticus commonly known as Nile Tilapia, is a widely distributed freshwater fish, largely consumed in Nigeria. Intestinal parasites pose a significant threat to its cultivation and consumption. This study aimed at determining the prevalence and molecular characterization of parasites isolated from Nile Tilapia collected from Ureje reservoir, in Ado-Ekiti, Nigeria. A total of two hundred and forty live Tilapia fishes were examined for intestinal parasites using a combination of microscopy and molecular techniques. The Oreochromis niloticus samples were examined for intestinal parasites using a combination of microscopy and molecular techniques. The parasitological examination of Oreochromis niloticus from Ureje Reservoir revealed the presence of five different species of intestinal parasites namely Schistosoma japonicum, Schistosoma mansoni, Ascaris lumbricoides, Eustrongylides sp., and Ancylostoma duodenale. Among the identified species Schistosoma japonicum had the highest number of occurrences (189) and Ancylostoma duodenale had the lowest number of occurrences (6). Microscopic analysis of fecal samples further confirmed the presence of parasitic eggs and cysts. The PCR and sequencing results confirmed the presence of Schistosoma japonicum, Schistosoma mansoni, Ascaris lumbricoides, and Eustrongylides sp. in the fish samples. The phylogenetic analysis (Fig. 1) further showed that the parasite isolates clustered closely with known reference strains, indicating that the identified species are consistent with those reported in other studies. The study concluded that a high prevalence of parasitic infection of Tilapia fish can pose a significant threat to human health. It is therefore recommended that proper hygiene and proper cooking conditions are maintained in the preparation of Tilapia fish for consumption
Addition of Bacillus sp. as a Bioremediation Agent on the Water Quality for Nile Tilapia (Oreochromis niloticus) Fry
Tilapia (Oreochromis niloticus) is a freshwater fish species with high economic value, widely cultivated due to its rapid growth and relatively simple farming practices. However, one of the primary challenges in tilapia aquaculture is maintaining water quality, as poor conditions—resulting from factors such as temperature fluctuations, uneaten feed, and fish waste—can negatively impact fish growth and survival. One promising solution is the use of bioremediation systems, particularly probiotics such as Bacillus sp., to enhance water quality. This study aimed to determine the optimal dosage of Bacillus sp. probiotics as a bioremediation agent to improve water quality, as well as the growth and survival rates of tilapia fingerlings. The experiment used a Completely Randomized Design (CRD) with five treatments (P1: 0 ml/L, P2: 0.5 ml/L, P3: 1 ml/L, P4: 1.5 ml/L, P5: 2 ml/L) and three replications each, totaling 15 experimental units. The procedures included container preparation and water conditioning, acclimatization of test animals, probiotic application, water exchange and siphoning, feeding, and water quality monitoring. The best results were observed in treatment P4 (1.5 ml/L), with an absolute length increase of 4.15 cm, absolute weight gain of 3.49 g, a specific growth rate (SGR) of 3.24%/day, and a survival rate of 84.2%

Proximate and Major Mineral Composition of Five Commercial Marine Fishes from the Alipur Landing Center, Kuakata, Bangladesh
Fish is contributing a prominent role in the diet of Bangladeshis as an animal protein source. However, there is a dearth of knowledge regarding the nutrient composition of marine fish species. Therefore, five locally available and commercially important marine fish species, including Acanthopagrus datnia (Yellowfin seabream), Polynemus paradiseus (Paradise threadfin), Sillaginopsis panijus (Flathead sillago), Dendrophysa russelii (Goatee Croaker), and Lepturacanthus savala (Savalai hairtail), were collected from the Alipur fish landing center in Kuakata, Bangladesh. A total of 224 fish samples comprising 27 pooled samples (each containing 24-72 individuals) in triplicate of the five fish species were collected, and their proximate compositions (moisture, crude protein, lipid, and ash) and four major minerals (calcium, iron, phosphorus, and zinc) were analyzed. The proximate composition of the studied fish samples showed varying levels of protein (20.57-16.21 g/100g), moisture (77.27-71.48 g/100g), ash (2.03-1.58 g/100g), and lipid (4.61-2.33 g/100g). Among the species examined, A. datnia had a significantly higher protein content (P < 0.05) than the others, except for L. savala, which did not show a significant difference (P > 0.05). The lipid and ash contents were similar across the species, with no significant differences (P > 0.05). In terms of mineral content, A. datnia also provided higher levels of zinc, calcium, iron, and phosphorus compared to the other species, aligning with the recommended nutrient intake for children (6-23 months) and pregnant or lactating women. Overall, this study underscores the potential of these five fish species to enhance the nutritional well-being of vulnerable coastal communities in Bangladesh by supplying essential nutrients.
