Do brine shrimp need sunlight?

Brine shrimp are attracted to light so use a low light level, otherwise they will expend much of their energy (which lowers their quality) in an effort to remain near the light source. A 60- to 100-watt light will suffice but hatching will require higher light levels (2000 lux constant illumination).

Brine shrimp do not necessarily require direct sunlight for survival, but they do benefit from indirect natural light or artificial light sources. Light plays a crucial role in their natural ecosystem, influencing their behaviors and reproductive cycles. 

In their natural habitat, brine shrimp thrive in saltwater bodies like salt flats and saltwater lakes where sunlight indirectly affects their environment. Sunlight promotes the growth of algae, a primary food source for brine shrimp. Algae rely on light for photosynthesis, which provides essential nutrients for the shrimp.

In controlled environments, such as aquaculture setups, providing indirect natural light or using artificial lighting with a suitable spectrum (similar to natural sunlight) can mimic these conditions. This ensures that the brine shrimp have access to the necessary nutrients and maintain their natural biological rhythms.

However, it’s important to strike a balance. Excessive or prolonged exposure to intense light can lead to stress or even harm the brine shrimp. Therefore, providing a regular light cycle that mimics natural day and night patterns is crucial for their overall well-being.

While brine shrimp do not require direct sunlight, they do rely on light indirectly for their nutritional needs and biological rhythms. Controlled lighting, whether natural or artificial, is a vital consideration for maintaining a healthy brine shrimp culture.
