How did outboard motors and synthetic nets affect artisanal fisheries in developing countries?

In developing countries, the introduction of outboard motors and synthetic nets has been a significant driver of modernization for artisanal fisheries, which traditionally relied on canoes, oars, and sails.12

These technological advancements enabled artisanal fishers to increase their catches significantly, helping to boost protein supplies for local populations. The adoption of outboard motors allowed for the use of larger boats and improved mobility, while the transition from traditional natural fibers—such as linen and hemp—to rot-proof synthetic fibres represented a major advance in gear durability and efficiency.13

While these innovations supported development, they also contributed to broader challenges in the fishing industry. The rapid increase in global fishing capacity following World War II eventually led to concerns regarding the sustainability of marine resources, as many fish stocks became fully exploited or overfished. Consequently, the shift toward more intensive fishing methods highlights the ongoing ethical necessity of balancing the immediate need for food security with the long-term preservation of biodiversity and marine ecosystems.1
