The text emphasizes the importance of small-scale tuna fisheries in local economies, sustainable development, and global food security. These fisheries, which use one-by-one fishing techniques, employ local workers and contribute to the wealth and livelihoods of coastal communities. They also prioritize sustainable practices by only catching a percentage of fish, allowing the rest to breed for future years, and minimizing bycatch and plastic pollution. Additionally, these fisheries play a significant role in supplying ethically sourced and eco-conscious tuna products to both local and international markets.
