The brown seaweed Ecklonia maxima, commonly referred to as sea bamboo, forms highly productive ecosystems that support a wide range of marine life and deliver numerous ecosystem benefits. Found along the temperate coastline of South Africa and Namibia, this remarkable species is gaining attention for its antioxidant and anti-inflammatory properties, which have sparked interest in its use for functional feeds and nutraceuticals in aquaculture.
Various studies have highlighted its nutritional value and environmentally benefits, showcasting its potential as a sustainable feed supplement for aquatic species.
In a research for sustainable replacements for fishmeal, this seaweed-rich in bioactive compounds such as phlorotannins, fucoidans, and essential vitamins-offers significant benefits for fish health and growth.
Studies have shown that incorporating this seaweed into aquafeeds enhances growth performance, optimizes feed efficiency, and strengthens immune responses, making it an ideal candidate for sustainable aquaculture systems.
The inclusion of Ecklonia maxima in aquafeeds not only improves nutrient retention but also promotes gut health and resilience to stress in fish. These advantages contribute to higher survival rates and overall improved productivity in aquaculture systems.
Optimal Inclusion Levels
A research on the use of seaweed in feeds for species such as abalone and tilapia suggest that optimal inclusion levels range between 5% and 15%, depending on the species and production conditions. This variability highlights the need for further research to standarise dosage levels and maximise its application across diverse aquaculture systems.
The potential of Ecklonia maxima goes beyond aquafeeds. It is being studied for its role in improving water quality, contributing to bioremediation, and even in pharmaceutical applications. Its versality makes it a valuable resource for sustainable innovation.
The future lies in achieving sustainable and economically viable cultivation of this seaweed while refining species-specific inclusion strategies. By addressing these challenges, Ecklonia maxima could become a cornerstone in environmentally friendly aquaculture practices.
