The stocking-week decision for Box A (2 ha) with only 2 pumps and no solar before stocking. Full pre-dawn DO simulation for 50k / 60k / 70k fingerlings from 15 g to 450 g, aeration kW needed at each stage, and the max safe density with water-exchange protocol. Land lease (₱24.62/kg rent — rejected) vs solar (₱3.99/kg) decision. Big financial table: all three densities × ₱140 and ₱160/kg, with breakeven and "viable on 2 pumps?" column. Verdict: stock 60,000, run both pumps nightly, manage DO on the tide → ~21,400 kg, ₱1.57M net @ ₱160/kg.

The grid can't power aeration — this solves it. Full O₂ demand math (17,000 kg biomass → 51 kg O₂/night → 3 kW minimum), confirming the 3 floater + 2 venturi spec. Three pathways costed in pesos: Solar (~₱855K, free power, ₱75/kg breakeven), Generator (₱210K + ₱27.5K/mo diesel), and Land Expansion (needs 14 ha, ₱83/kg — rejected). Verdict: generator now, solar as the permanent build. Box B grid-load test + BFS-016 breakeven integration included.

Month-by-month checklist from June stocking through November harvest. Biomass status cards with danger levels, daily DO log tables (5 AM + 2 PM), ammonia load tracking, Box A vs Box B comparison tracker, feed switch triggers, and a dedicated October critical-window alert. Month 4 (Oct) flagged red — 870 kg TAN/day, 10× stocking load.

Complete experiment design: Box A (control, 3.4 ha, 68k fish) vs Box B (probiotics, 1.1 ha, 22k fish) at 20,000/ha. Covers probiotics pathway decision, stocking density safety analysis, feeding zones & frequency, fingerling compression strategy, ammonia & waste load calculations, sugpo/vannamei polyculture assessment, master timeline (May 25 → June 1 stocking), and financial summary.

Visual blueprints for Box A (34,000 m²) and Box B (11,000 m²). Aerator placement maps with wiring run lengths and weatherproofing specs (IP rating, conduit, junction box placement). Feeding zone maps based on water flow patterns. Standalone reference file.

Complete decision framework: Pathway A (lablab natural food) vs Pathway B (feeds-only from Day 1). Covers PAGASA weather analysis, habagat onset risk, wipe-out chemical comparison (CaO/Ca(OCl)₂/teaseed with costs), financial model per pathway, rainy season salinity protocols, betaine/Vitamin C feed additive stack, apparatus list ≤₱50k, and DIY perforated-pipe aerator build. Two decision gates (Jun 15 + Jun 25). Verdict: GO LABLAB.

Interactive tide chart for Paombong / Manila Bay (May–June 2026). Day-by-day drain schedule for 2 × 24" gates + 4DR5 pump. May 22 drain start. Neap bottom work window. Chemical options (no teaseed — lessee cleanout). Lablab-in-rain analysis with El Niño outlook. Fingerling fallback: order 100k (50k/box) at 80% survival = ₱120K–₱170K. Draggable decision cards.

Alternative to BFS-012. No quicklime — teaseed cake (saponin) for pest fish eradication, urea-primary fertilization. Saves ₱43,500–₱57,000 vs lime pathway. Faster: 48 days to stocking vs 55. Gate: soil pH must be 6.5–8.5. Includes council expert assessments, probe questions, alternatives table (tobacco/manure), emergency recovery (unauthorized chemical = skip teaseed).

v2 REVISED — Inorganic-only protocol (no chicken manure, no tobacco). Quicklime CaO sanitizer. CRITICAL: 14-day lime-phosphate gap rule (stocks July 9, not June 28). ImmunoDefence Aqua (UPLB) + molasses protocol. Water change + probiotic interaction explained. Lablab-to-feed transition at Day 45–60. Full cycle budget: ₱729K cost / ₱783K net / 52% margin.

SBS Philippines catalog analysis for milkfish. New find: Betaine (euryhaline osmoprotectant — most underutilized lever for bangus specifically). Compound enzyme blend (phytase + protease + xylanase upgrade). Lysine HCL. Choline Chloride. Box 1 vs Box 2 trial design. Pellet-coating method — no pelleter needed. Stack cost: ₱5–9k/box/cycle → ~₱60–80k feed savings.

6 peer-reviewed interventions to boost grow-out speed and FCR — no aerators needed. High-protein starter feed (SEAFDEC 2025 missing piece), phytase enzyme (direct milkfish PJS study), partial harvest at Day 40–60, water exchange protocol, lablab fertilization, and 3rd daily feeding. Combined uplift: +₱1.4–2.0M/yr vs baseline.

SEAFDEC-AQD 2025 trial analysis. Scholarly research on Bacillus/Lactobacillus strains. Philippine-sourceable products (UPLB BIOTECH, OGANIKKU). Caretaker protocol for Rain. Box 1 (probiotic) vs Box 2 (control) — +₱307k net/box/cycle projected. Safe with sugpo.

4 stocking size scenarios (fry ₱0.50 → 10-14cm ₱8.60) with full financial model. Sugpo vs vannamei comparison. No aerators needed. Side-by-side bangus-only vs bangus+sugpo analysis. Box 1 & 2 cycle schedule. Sugpo adds ₱1.36M over 3.5yr at near-zero complexity.

Lease signed. Farm prep May 15. Box A (30k+40k) vs Box B (40k+50k) full financial comparison — 3 price scenarios, cash flow timeline, chemical prep guide, week-by-week farm timeline. Verdict: Box A Year 1.
