How to Choose

What research and experts say

Scientific literature and aquaculture research consistently highlight the nutritional strengths of krill and other marine zooplankton for carnivorous and omnivorous aquatic animals. For reptile and amphibian keepers, key takeaways are that high-quality krill provides concentrated protein, essential fatty acids and pigments that support growth, immune function and natural colouration. Freezing preserves many of these nutrients while offering safe, portioned feeding that reduces waste and handling stress. While species-specific needs vary, beginner-friendly studies and reviews point to krill as an effective component of varied diets when used alongside other feeds and vitamin/mineral supplementation where required.

High-quality krill supplies digestible protein and amino acids important for growth and tissue repair.

Krill is a natural source of omega-3 fatty acids (EPA and DHA) and astaxanthin, which support skin health and colouration.

Freezing preserves nutrients and reduces spoilage and parasite risk compared with fresh-only alternatives when handled correctly.

Chitin from krill can be a natural component of diets for crustacean-eating species and may influence gut microbiota and digestion.

Consistent portion sizes improve feeding repeatability, reduce overfeeding and help monitor appetite and health.

Sustainability and traceability matter: look for brands that disclose sourcing and responsible harvest practices where possible.
