Nature-based aquaculture is emerging as a promising and environmentally friendly alternative for sustainable food production, according to Dr. Alok Kalla, head of aquaculture at the Ministry of Fisheries and Forests. During the Aqua-Pearl Stakeholder Inception and Workshop held in Suva, he emphasized that while traditional aquaculture has its importance, it often results in ecological harm through pollution, habitat loss, and overfishing.
Dr. Kalla highlighted that nature-based aquaculture aims to replicate natural ecosystems by blending aquaculture with conservation efforts. He explained that this approach involves restoring and preserving natural habitats such as mangroves, seagrass beds, and coral reefs. These ecosystems not only support diverse marine life but also play crucial roles in filtering water, safeguarding coastlines from erosion, and capturing carbon dioxide.
Another significant point raised by Dr. Kalla was the shift towards using sustainable feed options, moving away from traditional fishmeal and fish oil, which are typically sourced from wild-caught fish. Instead, nature-based aquaculture promotes feed alternatives derived from plants, insects, and algae, thereby reducing the ecological footprint of aquaculture while ensuring the health of farmed species.
Furthermore, Dr. Kalla underlined the potential of nature-based aquaculture in addressing climate change. By restoring coastal ecosystems, it can enhance their ability to sequester carbon and protect coastal communities from rising sea levels and severe weather events. He called upon stakeholders to adopt sustainable practices in aquaculture, which could significantly contribute to a low-carbon future.
In conclusion, Dr. Kalla’s vision for nature-based aquaculture represents a hopeful pathway towards a sustainable and equitable future. By embracing these innovative practices, there is potential for aquaculture to not only meet food demands but also protect and preserve vital marine ecosystems for generations to come. This approach stands as a testament to how environmental dedication can lead to nutritious food production while fostering ecological balance.
