Abstracts
This study examines the impact of area, yield, and their interactions on changes in shrimp production within India's coastal states' culture fisheries sector. Using secondary data from the Marine Products Export Development Authority (MPEDA), Government of India, spanning from 2011-12 to 2020-21, the analysis is segmented into two periods: period I (2011-12 to 2015-16) and period II (2015-16 to 2020-21). Employing a Decomposition Model, the study dissects the total change in fisheries production into three components: the Area effect, the Yield effect, and the Interaction effect. The findings underscore the significance of areas expansion in driving shrimp production, with the area effect dominating over yield and interaction effects in most coastal states. Karnataka and Goa exhibited unique dynamics, while Kerala and Goa showcased the highest area, yield, and interaction effects, respectively. The study provides valuable insights for strategic decision-making in sustainable aquaculture growth and resource management.
