2. BSF Farming: Breeding and Rearing
Black Soldier Fly farming involves two main distinctive parts: breeding (reproduction) and rearing/processing. Whist breeding focuses on producing a steady supply of healthy larvae using specialized knowledge, and the rearing and processing aims to convert the larvae into valuable products efficiently.
The insect breeding or reproduction phase requires a deep understanding of biology to optimize the conditions for mating and egg production. Breeders set up a lab, maintain colonies, and adjust environmental factors to encourage the production of healthy larvae. Incubated eggs then hatch into larvae, which are fed food waste “formulas” to stimulate growth.
The next phase involves rearing and processing. In this stage, similar to a traditional food chain, mature larvae are harvested and processed into products such as protein, fertilizer, and oil. Rearing focuses on managing the larvae’s environment and feed, ensuring constant growth. Processing involves converting the larvae into a saleable form, mirroring traditional food production principles.
Breeding Black Soldier Flies
Effective insect farming relies on techniques and best practices to increase breeding productivity. The correct methods can help improve insect production, keep insect colonies healthy, and produce top-quality insect-based products. Here are key points to remember:
Colony Management
Colony management: Proper management ensures healthy and productive insect colonies. This includes mimicking the insects’ natural habitat through ideal housing conditions like suitable temperature, humidity, and ventilation. Regularly monitoring colonies to detect signs of stress, diseases, or overcrowding safeguards the insects’ well-being.
Managing a Black Soldier Fly colony entails several challenges, particularly ensuring a stable egg output for consistent production. Fluctuations in environmental factors can disrupt egg-laying cycles, leading to irregular egg production. Additionally, managing colony hygiene and preventing the buildup of pathogens or pests is essential to sustain a healthy and productive BSF population.
Environmental Control
Farming facilities need the right systems to regulate environmental factors like temperature, humidity, and lighting, all of which significantly affect insect growth and productivity. Monitoring and adjusting these parameters creates optimal conditions for insects. The regulation considers BSF to be livestock. It’s crucial to maintain BSF’s good hygiene in farming facilities to prevent diseases and ensure the quality of insect-based products. Regular cleaning and disinfecting of equipment, housing units, and feeding areas help minimize contamination risks.
Colony Health
Maintaining the health and genetic diversity of a BSF colony is paramount for sustainable insect production. Best practices for colony health include regular monitoring of population dynamics, disease prevention through biosecurity measures, and maintaining optimal environmental conditions. Introducing genetic diversity through periodic introductions of new genetic material or strains helps prevent inbreeding depression and promotes robustness within the colony. Additionally, implementing strict hygiene protocols, providing balanced nutrition, and minimizing stressors such as overcrowding contribute to overall colony health and longevity.
Life Suspension Technology
Preservation techniques like FreezeM’s proprietary live suspension technology, called PauseM®, temporarily stop the BSF life cycle at various stages, marking the advent of controlled insect farming for the first time.
The capability to pause the BSF neonate life cycle for 14 days facilitates the establishment of breeding hubs designed to streamline outsourced breeding in a Breeding-as-a-Service model, catering to diverse rearing and processing needs across various facilities globally.
Three Flexible Breeding Models
While the in-house model was the preferred breeding choice for insect farming companies in the early days of the industry, it is now clear that this approach involves many risks that are unfavorable to investors and companies seeking rapid growth.
Outsourced Breeding
Establishing a breeding unit requires approximately 20% of the overall factory cost and area. In addition, it requires specialized personnel with expertise in biology, entomology, and genetics. Leaving the breeding hassle with FreezeM eliminates the need to develop a reproduction line, hatching, and dosing technologies.
Hybrid Breeding Model
When taking a hybrid in-house and outsourced reproduction approach, farmers can choose to replace a significant part of their breeding with outsourced supply to make their in-house breeding processes more efficient and more standardized, ensuring production contingency.
In-House Breeding Model
Vertically integrated farms include breeding processes in-house. These require strict control over colony management, environmental control, and colony health, as seen above. It’s good practice to supply these BSF colonies with periodic genetic boosts from different BSF lines. Such genetic enrichment results in a healthier colony, with improved neonates’ robustness, growth, and stability.
3. Rearing in Black Soldier Fly Farming
