Philippine wet markets generate over 70 kg of fish waste daily. Promoting traditional reuse practices and incentivizing waste utilization can boost the circular economy and create income.

Area of Science:

Fisheries Management
Waste Management
Circular Economy

Background:

Improper fish waste management threatens Philippine fisheries sustainability.
Wet markets are significant sources of fish waste.
Understanding current practices is key for effective intervention.

Purpose of the Study:

To determine existing fish waste management systems in Philippine wet markets.
To compare waste management practices across different municipalities.
To identify opportunities for promoting traditional and innovative waste reuse.

Main Methods:

Stakeholder interviews within the fisheries industry.
Market-level data collection on fish waste handling.
Comparative analysis of waste disposal, sale, and giveaway practices.

Keywords:

Aquaculture Blue economy Circular economy Fisheries Solid waste management Sustainability

Main Results:

Average daily fish waste production in wet markets is 70.3 kg, with no significant location-based differences.
Disposed waste averaged 32.3 kg, sold waste 18.9 kg, and given away waste 19.1 kg per market.
Rural areas showed significantly higher fish waste reuse rates than Metro Manila.

Conclusions:

Incentivizing fish waste innovation and promoting traditional reuse practices are crucial for the Philippine circular economy.
Effective waste management can provide alternative income streams for fisheries stakeholders.
Tailored interventions at the municipal level can enhance fish waste utilization.
