Sustainable Aquaculture in India: Environmental and Economic Assessment in West Godavari, Andhra Pradesh

Aquaculture has become a cornerstone of rural livelihoods and food security in India, particularly in Andhra Pradesh where districts such as West Godavari have evolved into high- density shrimp and fish farming zones. Despite considerable economic gains in export revenues and rural employment, questions remain regarding the ecological costs and long- term economic resilience of small and medium-scale farmers. Building on prior studies, this paper addresses gaps in micro-regional sustainable-aquaculture research by (i) explicitly stating and testing hypotheses grounded in ecosystem and resilience theory, (ii) validating our survey instrument (content validity index = 0.89; Cronbach’s α = 0.87), (iii) applying advanced quantitative techniques (exploratory factor analysis, structural equation modeling) alongside rigorous thematic analysis, and (iv) offering an integrated framework for policy and practice. Data were collected January–March 2023 via a cross-sectional survey of 200 stakeholders (farmers, input suppliers, institutional actors) and 30 in-depth interviews across five mandals in West Godavari. Structural equation modeling confirms that intensive input use (chemicals, high stocking densities) significantly predicts environmental degradation (β = 0.52, p < 0.001), which in turn negatively affects farm profitability (β = –0.65, p < 0.001). Adoption of sustainable practices (water recycling, polyculture) mitigates these effects (indirect standardized effect = +0.22, p < 0.05). Qualitative analysis yielded three major themes—“Ecological Risk Awareness,” “Economic Vulnerability,” and “Adaptive Innovation”—each illustrated by farmers’ verbatim statements. We discuss theoretical contributions to triple-bottom-line sustainability models, outline practical extension and credit mechanisms, and propose policy reforms including aquaculture zoning, zero-discharge mandates, and sustainability-linked finance. This study provides a robust empirical foundation for steering India’s aquaculture toward long-term ecological integrity and economic resilience

Enhancing Market Reach and Profitability in the Indian Aquaculture Industry

The Indian aquaculture industry, a global leader, faces persistent challenges in marketing, pricing, and supply chain management that limit profitability and market expansion. This study investigates how marketing channels, pricing strategies, and supply chain practices influence commercial success, focusing on West Godavari (Andhra Pradesh), Hooghly (West Bengal), and Kollam (Kerala). Semi-structured interviews with 45 stakeholders, including farmers, marketers, and supply chain managers—reveal that using online platforms and targeting export markets significantly enhances reach and profitability. Value-based pricing improves margins by aligning prices with product quality and customer perception. Efficient supply chain management, particularly through blockchain and automation, is vital for maintaining product integrity and meeting market demands. However, high implementation costs, lack of technical expertise, and resistance to change hinder adoption, especially among smaller operators. The study concludes that sustainable growth requires integrating diversified marketing strategies, value-driven pricing, and tech-enabled logistics. Key recommendations include investing in digital tools, embracing innovation, and fostering stakeholder collaboration to address operational barriers and strengthen the industry’s economic impact
