Analysing Stability and Shifts in Marine Fish Production of Maharashtra, India

Trend Analysis of Marine Fish Production

Abstract

The study investigates the dynamics of marine fish production in Maharashtra, India, spanning four decades (1981- 2020) at the district level. It utilises metrics such as Compound Annual Growth Rate and instability measures- Coefficient of Variation and Cuddy Della Valle Instability Index to analyse and explore the factors influencing marine fish production trends. The study reveals positve growth in marine fish production until 2010, after which the state recorded a negative CAGR of -0.43% from 2011 to 2020. Greater Mumbai consistently exhibited low instability in the last two decades, while Sindhudurg displayed the highest instability in the 1991–2000 period. Greater Mumbai consistently dominated marine fish production in Maharashtra, contributing nearly 40% to the state’s production in the last decade. However, Sindhudurg experienced a decline in its contribution over the years. The classification of districts into categories based on growth rate and instability provides insights into the factors influencing fish production. The study highlights the transition from non-mechanised to mechanised fishing boats, with over 80% of boats being mechanised in recent years, positively impacting production. Additionally, the development of fishing ports and financial assistance in the form of fishing gear have influenced marine fish production. The findings are crucial for policy formulation, sustainable fisheries management, and the well-being of the state’s coastal communities. They underscore the need for continued monitoring and strategic interventions to ensure the long-term sustainability of marine fishery resources in Maharashtra.
