Grubslive

Grubslive is a term used to describe a live-grub production and distribution system designed to supply live beetle larvae, such as mealworms, for use as animal feed. The concept emphasizes modular facilities, on-demand production, and direct shipments of live larvae to farms, pet-care operations, and fishing suppliers. The term has appeared in agritech discussions since the early 2020s and is used variably to refer to both production platforms and supply chains that focus on live larvae rather than dried or processed forms.

Operation centers on controlled-environment rooms where substrates—such as bran, cereal byproducts, or other organic matter—support larval growth. Temperature, humidity, and sanitation are automated to optimize yield and minimize contamination. Harvest typically involves separating mature larvae from spent substrate, followed by washing, viability checks, and rapid packaging to maintain live status during transport. Some models integrate waste streams by recycling spent substrate as compost or energy input.

Applications include aquaculture and poultry feed, as well as bait for sport fishing and for reptile-keeping sectors. Proponents cite higher protein content per unit weight, reduced reliance on traditional fishmeal, and the ability to repurpose agricultural byproducts. Critics highlight logistical complexity, higher perishability, and regulatory challenges around transporting living organisms and maintaining product quality during transit.

Regulation and safety considerations vary by jurisdiction. Grubslive operations address biosecurity, animal welfare, and transport rules, with standards typically covering cleanliness, traceability, nutrition labeling for mixed feeds, and controls to prevent unintended release of non-native larvae. Market adoption remains niche but is expanding in regions prioritizing sustainable protein sources for feed.
