Recorded readings
Initial commercial hatch: approximately 100,000 fry on 1 August 2026.
What happened
Jentan commenced commercial hatchery operations on 1 August 2026 with an initial hatch of approximately 100,000 fry. The first cycle was important not only as production output, but as a baseline for understanding how the new hatchery, water-treatment chain and RAS support systems behaved under real operating conditions.
What we observed
The first weeks reinforced a basic hatchery lesson: large numbers at hatch are only the starting point. Survival depends on disciplined control of water quality, stocking, feeding, aeration, circulation and handling. Early mortality must therefore be investigated as an operating signal rather than treated only as a production loss.
What we learned
- Record the hatch date and estimated number.
- Track mortality every day.
- Measure critical water parameters before making treatment decisions.
- Separate assumptions from measured observations.
- Use each production cycle to improve the next one.
Farmer takeaway
A first hatch should be treated as both a production event and a learning cycle. The quality of the records created during the first few weeks can determine how quickly a new hatchery improves its survival, consistency and cost control.
