Semi-Intensive & Intensive Pond Culture — 1ha / 2ha Scenarios — Tateh Feed Plan — Equipment Costs — Fry vs Fingerling Decision — Bulacan 2026
BFS-004 is a ground-up revision of BFS-003 with confirmed budget, reduced payroll, Tateh stage-specific feed costs, equipment pricing, and a fry-vs-fingerling decision framework. The payroll reduction from ₱456,000/year (two managers) to ₱150,000/year (one manager, Gary remote) transforms the economics: every scenario that was marginal in BFS-003 is now solidly profitable.
Semi-Intensive 2ha @ 20K/ha. ₱1.5M working capital. Medium risk. Proven method. Recommended for Gary.
All 4 scenarios fit within budget. Semi-Int 2ha uses ₱1.5M, leaving ₱500K reserve. Intensive 2ha uses the full ₱2M.
From ₱456K (BFS-003: 2 managers) down to ₱150K (1 manager + Gary remote). This single change flips every 1ha scenario from loss to profit.
Traditional Extensive is eliminated from BFS-004. It yields only 1,200–1,700 kg/ha/year on natural food (lablab) alone — never enough to cover even one manager's salary at any scale tested. The two viable methods for Gary:
| Parameter | Semi-Intensive | Intensive |
|---|---|---|
| Feed Source | Natural food base (lablab) + supplemental Tateh commercial feed from month 2–3. Fed at 2–3% body weight/day. | 100% commercial pelleted feed (27–31% protein). Fed 3–4x daily from stocking. Aeration required. |
| Stocking Density | 10,000–25,000/ha (modeled at 20,000/ha) | 20,000–50,000/ha (modeled at 20,000–25,000/ha) |
| Survival Rate | 80–85% (modeled at 80%) | 75–85% (modeled at 78–80%) |
| Harvest Weight | 330g (3 pcs/kg) in 4–5 months | 400g (2.5 pcs/kg) in 4–5 months |
| Cycles per Year | 2 (with pond prep between) | 2 (faster growth but same cycling) |
| Yield (kg/ha/year) | 5,700–6,700 | 8,000–13,000 |
| Feed Cost / ha / cycle | ₱95,000–₱175,000 (Tateh) | ₱200,000–₱350,000 (Tateh) |
| Aeration | 1–2 paddlewheels recommended at 20K density | 2–4 paddlewheels required. Backup generator essential. |
| Payroll (BFS-004) | ₱150,000/yr (1 manager) | ₱150,000/yr (1 manager) |
| Capital Required (1ha) | ₱600K–₱800K | ₱1.0M–₱1.4M |
| Risk Level | Medium (feed cost volatility, manageable) | High (oxygen crash = mass kill, power outage risk) |
Stocking density is the single biggest lever for revenue. Higher density = more fish = more revenue, but also more feed cost, oxygen demand, and risk. Here is the research-backed density guide:
| Method | Standard Density | Max w/ Aeration | Practical Startup Max | Risk at Max |
|---|---|---|---|---|
| Semi-Intensive (no aerator) | 10,000–15,000/ha | — | 15,000/ha | Medium |
| Semi-Intensive (1–2 aerators) | 15,000–20,000/ha | 25,000/ha | 20,000/ha | Medium-High |
| Intensive (full aeration) | 20,000–30,000/ha | 40,000–50,000/ha | 25,000/ha | Very High |
| Feed Stage | Product | Weight Range | Growth per Fish | FCR | Price / 50kg Sack |
|---|---|---|---|---|---|
| Pre-Starter | Tateh crumble | ~2g → 25g (fry nursery) | 23g | 1.50 | ₱1,200 |
| Starter | Tateh crumble/pellet | 20–25g → 70g | 50g | 1.50 | ₱1,150 |
| Grower | Tateh pellet | 70g → 170g | 100g | 1.40 | ₱1,050 |
| Finisher | Tateh pellet | 170g → 330g (harvest) | 160g | 1.35 | ₱1,000 |

| Total (fry start) | 458g | 458 kg = ~9.2 sacks | |||
Assumes 80% survival for fingerling starts, 70% survival for fry starts (nursery phase). Feed is purchased for stocked quantity but mortality reduces consumption over cycle. Feed calculations below account for 80% average feeding rate (fish die throughout the cycle, not all on day 1).

| D: Intensive 2ha 20K | 2 ha | Intensive | +₱2.01M | CAUTION / GO | ₱2.0M | HIGH |
Budget: ₱700K. Leaves ₱1.3M reserve. Medium risk. Good if Gary wants to start small and prove the concept before scaling.
Budget: ₱1.5M. Leaves ₱500K reserve. Medium risk. Best risk-adjusted return. One manager handles 2ha semi-intensive.
Budget: ₱1.2M. Higher profit than A but HIGH risk. Oxygen crash, ₱240K/yr electricity. Not for first-time remote operator.
Budget: ₱2.0M (full budget, zero reserve). Highest ceiling. Only pursue if experienced manager is hired and backup capital secured.
Gary has confirmed a 2-year lease commitment. Here is how that affects capital planning:
| Parameter | 1 ha | 2 ha |
|---|---|---|
| Annual lease | ₱40,000/year | ₱80,000/year |
| Total 2-year commitment | ₱80,000 | ₱160,000 |
| % of ₱2M budget | 4% | 8% |
| Payment timing | Typically 1 year advance + 1 year at renewal, or full 2 years upfront for discount | |
| Scenario | Min. Farmgate Price to Break Even | Min. Survival Rate to Break Even | Margin Above Current Price (₱130–170/kg) |
|---|---|---|---|
| A: Semi-Int 1ha 20K | ₱90/kg | 65% | ₱40–80/kg cushion |
| B: Semi-Int 2ha 20K | ₱75/kg | 55% | ₱55–95/kg cushion |
| C: Intensive 1ha 25K | ₱105/kg | 68% | ₱25–65/kg cushion |
| D: Intensive 2ha 20K | ₱90/kg | 60% | ₱40–80/kg cushion |
1.6 ha semi-intensive grow-out + 0.4 ha nursery. Buy fingerlings for Cycle 1, run nursery in parallel. Expected net at ₱140/kg after all costs.
Self-produced fingerlings from nursery reduce stocking cost by ₱100K+/year. Optimized feeding routine improves FCR. Consider adding 3rd hectare.
Options: Expand to 3–5 ha semi-intensive OR add 1ha intensive alongside existing semi-intensive. Use 2 years of experience to decide.
