Spearfishing

Spearfishing is an ancient method of fishing that involves using a spear to catch fish underwater. Unlike some modern fishing techniques that can be harmful to marine ecosystems, spearfishing can be practiced in a sustainable manner when done responsibly. The Tagbanua people use spearfishing along with seasonal fishing to ensure their fisheries are sustainable.

Turtle Exclusion Devices
Sustainable fishing methods are focused on minimizing environmental effects, because of this gear modifications can be made, such as Turtle Exclusion Devices. In catfish surveys in Missouri, USA, turtle bycatch has shown to be a large issue. With modifications to the devices used to capture catfish, there was an 84% decrease in turtle bycatch, with no decrease in catfish capture rates.

Seasonal Fishing Practices
Seasonal fishing can play a crucial role in promoting the sustainability of fisheries by allowing fish populations to reproduce and replenish. By implementing seasonal fishing restrictions, fisheries management can ensure that fishing activities are carried out when fish are most abundant and actively spawning, thus reducing the risk of overfishing. Additionally, seasonal fishing can help protect vulnerable life stages of fish and avoid harming spawning habitats. Seasonal fishing practices can contribute to the long-term health of fisheries and support ecosystem resilience.

Marine Protected Areas (MPAs)
Marine Protected Areas (MPAs) are areas where fishing is prohibited and offer a chance to enhance biodiversity conservation. Over the past 20 years, the world has increased the global MPA area from about 5 million square kilometers to about 28 million square kilometers. Out of all sustainable fishing practices, MPA’s have the most potential for positive ecological effects, showing significant increases in fish biomass.
