Modeling management strategies for shrimp farming impact on the coastal delineation near the Northern Bay of Bengal in Bangladesh

Abstract

Shrimp farming aquaculture in coastal regions of Bangladesh near the northern Bay of Bengal has become a significant industry contributing notably to nation’s economy through exports and local consumption. Several studies reveal that the shrimp farming leads to significant socioeconomic changes, environmental degradation by heavy metal contamination and toxic substances like NH₃, NO₂−, and H₂S, blue - green algae posing risks to both marine life and human health. Using primary and secondary data including field experiments, FGDs, KIIs and questionnaire surveys in coastal districts, this study aims to analyze perception towards socio-environmental impact of shrimp aquaculture and design an integrated management strategies model for sustaining the shrimp farming practices in coastal world. The statistical test result (F = 1.202, p = 0.312) shows that most of the impact factor variables associated with socio-environmental degradation had no significant effect individually; rather, the combined contributions of multiple variables shaped the complex challenges in coastal arena. To face these, the study develops an Integrated Management Framework applicable in international context for sustainable shrimp farming addressing the environmental, socio-economic and governance strategies through micro, meso and macro scales to guard the combined effects. The framework integrates five established key models (DPSIR, SAF, ERA, SES and EMS) for viable shrimp farming through baseline assessment, stakeholder involvement and governance strategies. Coupled VRIO-SWOT analysis helps to evaluate the model’s competitive advantages and sustainability. The model’s KPIs can offer actionable sustainable approach for international policymakers, industry stakeholders and researchers for enhancing eco-friendly aquaculture practices across diverse international coastal contexts.
