Common name: Nannochloropsis
Nannochloropsis is a genus of microalgae that has gained significant attention in the aquarium hobby for its role in aquaculture and as a nutritional supplement for marine organisms. These unicellular algae are known for their small size, typically ranging from 2 to 5 micrometers, and their ability to thrive in a variety of aquatic environments, including both marine and freshwater systems. Nannochloropsis is prized for its high content of omega-3 fatty acids, particularly eicosapentaenoic acid (EPA), which makes it an excellent food source for filter-feeding invertebrates, larval fish, and other marine organisms that require high-quality nutrition.
In the context of reef aquariums, Nannochloropsis can be used to culture rotifers and other zooplankton, which are then fed to corals and fish. This microalgae is often cultivated in home aquaria for its ease of growth and its ability to enhance the nutritional profile of live feeds. Additionally, Nannochloropsis can play a role in nutrient cycling within the aquarium, as it can absorb nitrates and phosphates, contributing to improved water quality.
From a scientific perspective, Nannochloropsis is also studied for its potential in biofuel production due to its high lipid content. However, in the aquarium hobby, its primary value lies in its contribution to a balanced and nutritious diet for marine life. When cultivating Nannochloropsis , hobbyists should ensure adequate lighting and nutrient availability to maintain healthy growth, and they should be mindful of preventing contamination from other unwanted algae species.
