Bloodworms (Chironomus spp.) are the aquatic larval stages of different species of non-biting midge flies and form an important part of the aquatic food chain as nutrient recyclers by taking up nutrients (through grazing, scraping, collecting etc.) produced by primary consumers (e.g. photosynthesizing algae, bacteria, micro-algae & macrophytes). They provide these nutrients to the next trophic level (secondary consumers) and as such form an important food source for other aquatic insect larvae, amphibians, freshwater fish, and wading birds.

The bloodworms we offer for sale are harvested manually from riverbeds and man-made ponds in northern China. We only receive live bloodworms and purge them in our facility in aerated holding tanks in which the water is continuously cycled through a filtering and disinfecting system (ozone based).

We offer our bagged frozen bloodworms in resealable (zip-lock) LDPE bags in the following sizes:

• SKU 88053: 113 g (4 OZ), 12 bags packed in an inner-pack, 6 inner-packs per carton.
• SKU 88056: 227 g (8 OZ), 48 bags per carton
• SKU 88057: 454 g (16 OZ), 24 per carton

All bags are manually filled to safeguard product integrity and are frozen individually in our quick-freezer. Each bag contains a lot code and date of expiry for tracking purposes. Samples of each lot are submitted to an accredited laboratory for Salmonella analyses before being sold.
