| Abstract | The fishery sector is an important contributor to the economic development of India. India ranks second in fisheries and aquaculture production, with around 8% share globally. The Brahmaputra River, which is one of the largest rivers, along with its tributaries, supports about 217 species of fish, making it one of India⿿s most biologically productive inland water systems. The Brahmaputra River supports millions of people in northeast India through fishing and aquaculture, especially in the state of Assam. In 2023-24, the state alone achieved a fish production level of 4.74 lakh metric tons and contributed ⿹155.55 billion to the state's Gross State Domestic Product (GSDP). However, this sector faces various ecological and structural challenges. Increased rainfall variability, rising annual mean temperature, and frequent flooding are the key climatic changes that disrupt fish breeding cycles and reduce the water quality. In addition to this, overfishing, pollution, and unsustainable practices further degrade fish habitats and biodiversity. These combined factors have led to a significant decline in fish stocks. To address these challenges, this paper presents a data-driven modeling and simulation framework to quantify the effects of climatic and environmental variables on inland fish production in the Brahmaputra basin. By integrating the historical time-series data of fish landings with the required variables, the model aims to forecast the fishery outcomes under multiple scenarios. The results are intended to support the adoption of sustainable fishing practices and guide the development of context-specific policy interventions to meet the increasing demands of fish production. The combined model will thus offer a more complete solution by merging ecological, climatic, and acoustic variables to safeguard biodiversity and support resilient livelihoods in the region. |
