The Impact of Fisheries on the Economy: A Systematic Review on the Application of General Equilibrium and Input–Output Methods

Abstract

In this paper, a systematic literature review on the impact of fisheries on the economy and the application of the computable general equilibrium (CGE) and input–output (IO) methods for assessing this impact is conducted. The importance of fisheries as a food source, the over exploitation of this resource, and, consequently, the impact of fisheries on the economy are the motivations behind this study. By reviewing the applications of two of the most common economic modelling tools, we aim to shine light on the state of the art and how the impact of fisheries on the economy has been addressed in the literature. In this analysis, three main themes of socio-economic, ecological, and environmental have been identified, and the application of these methods in each theme has been considered. The results show that while IO methods continue to be applied in the literature, the CGE method has experienced increased application recently, and future applications are anticipated due to its enhanced capabilities in comparison with IO models.

Current Issues with Fish and Fisheries Sector: Challenges and Solutions

“…Fish prices can fluctuate significantly due to factors such as changes in consumer preferences, supply and demand dynamics and geopolitical events. These fluctuations can have a direct impact on the income and financial stability of fishers and industry stakeholders (Akbari et al, 2023). Subsidies provided to the fishing industry can distort market dynamics and encourage overfishing it means "Giving the fishing sector subsidies has the potential to manipulate market dynamics and promote overfishing".…”

“…Habitat destruction, driven by coastal development and industrial fishing practices, exacerbates the problem and disrupts fragile marine ecosystems. Climate change has exacerbated these issues, causing warmer waters, ocean acidification and changing migration patterns, posing significant threats to both fish stocks and the communities that depend on them (Akbari et al, 2023). In the economic realm, the fish and fisheries sector face a range of challenges, including market volatility, the scourge of illegal, unreported and unregulated (IUU) fishing and inequitable access to resources.…”

The Impact of Japan’s Discharge of Nuclear-Contaminated Water on Aquaculture Production, Trade, and Food Security in China and Japan

“…In addition, they secure essential micronutrients for human health, such as omega-3 fatty acids, amino acids, minerals, and vitamins [2]. With the continuous improvement in living standards, the demand for APs has grown significantly [3,4]. Since the blue revolution started in 1960, the global consumption of AP has nearly tripled, with the per capita consumption increasing from 9.0 kg in 1961 to 20.2 kg in 2020, exhibiting an annual growth rate of 3.2% [5].…”
