Fins4Future: Technical Progress Report on Sustainable Aquaculture in Tanzania
Project Overview
Fins4Future, in collaboration with Sustainable Agriculture Tanzania (SAT), is working to develop sustainable aquaculture solutions in Morogoro, Tanzania. Our mission is to enhance local fish farming practices through innovative and environmentally friendly techniques, aligning with global sustainability goals.
In this Blog we give an overview about our pilot project: F4F Hatchery for Tanzania
| Project Title | F4F Hatchery for Tanzania |
|---|---|
| Location | Morogoro, Tanzania |
| Year | 2025 |
| Fish Species | Tilapia, O. niloticus |
| Total Water Volume | 4 m³ |
| Capacity | 100 - 200.000 Fingerlings per Year |
| Technology; Power Consumption | Biofloc (Green Water); 35 W |
Tilapia Breeding and Biofloc Technology
Our primary focus is on tilapia aquaculture, a crucial source of protein in many developing regions. Tilapia is well-suited for farming due to its fast growth rate, ability to thrive in various water conditions, and high market demand. However, successful tilapia hatcheries require controlled breeding environments, high-quality broodstock, and efficient water management systems.
To optimize production, we have implemented biofloc technology, a sustainable method that enhances water quality and reduces waste. The biofloc system relies on microbial communities to convert organic waste into beneficial biomass, which serves as an additional food source for the fish. This method significantly reduces the need for frequent water exchanges and improves feed conversion rates, making it an environmentally and economically viable solution.
Key advantages of the biofloc system include:
1. Reduced water usage: Traditional fish farming methods require frequent water replacement, whereas biofloc recycles nutrients within the system
2. Improved fish health: The microbial environment in biofloc helps prevent disease outbreaks by maintaining stable water quality
3. Lower feed costs: Biofloc contributes to the fish’s diet, reducing reliance on expensive commercial feeds
Project Milestones and Successes
1. Tilapia Hatchery Established:
We successfully built and launched the first biofloc-based tilapia hatchery at SAT. This system is expected to produce between 100,000 and 200,000 fingerlings per year, supporting local farmers and improving regional food security.
2. Broodstock Acquisition:
We partnered with RG Fish Farm, acquiring high-quality tilapia broodstock to ensure a strong genetic foundation for the hatchery.
3. Training and Capacity Building:
We provided hands-on training for locals on post mortems, pond management, biofloc system maintenance, and alternative production techniques, such as Recirculating Aquaculture Systems (RAS) and In-Pond Raceway Systems (IPRS).
Challenges and Areas for Improvement
1. Equipment Limitations:
Many essential aquaculture tools are unavailable locally, requiring farmers to use improvised solutions. For example, tilapia are often caught using mosquito nets due to a lack of proper harvesting gear.
2. Feed Quality and Availability:
High-quality pelleted fish feed is scarce, leading to reliance on homemade alternatives that disintegrate quickly in water, reducing efficiency and increasing waste.
Moving forward, we aim to address these issues through strategic partnerships, technology transfer, and further investment in infrastructure.
Future Prospects and Expansion
Looking ahead, we plan to:
1. Expand our hatchery operations to increase fingerling production capacity.
2. Develop further training programs to equip farmers with technical knowledge in sustainable aquaculture.
3. Explore new partnerships to scale up production and improve supply chains for aquaculture inputs.
We remain committed to advancing sustainable aquaculture in Tanzania and beyond. Thank you for your continued support!
