FishMatch Group · Water Quality & Monitoring

Water quality systems that keep large aquaculture projects insurable, compliant and profitable.

Sensors, cameras, SCADA, IoT gateways and control loops — engineered for RAS, hatcheries, shrimp farms and offshore sea-cages. FishMatch Group prepares neutral, bankable water-quality architectures and issues confidential RFQs to project-matched international suppliers.

The full water-quality stack

In-water sensor arrays

Continuous DO, temperature, pH, ORP, salinity, TAN, NO₂ and NO₃ — the physiological envelope your biomass lives inside.

  • Optical DO for RAS, hatcheries, ponds and cages
  • Redundant sensors on every life-critical loop
  • Manual sampling protocol for cross-validation and drift audit
  • IP68 / marine-grade housings for offshore sites

Fish & shrimp behavior monitoring

Stereo cameras, hydroacoustics and computer-vision analytics for biomass, appetite, mortality and welfare.

  • Automated feeding-response and appetite control
  • Biomass estimation and average-weight tracking
  • Mortality detection and dead-fish collection triggers
  • Sea-lice / parasite counting on marine cages

Environmental & benthic monitoring

Currents, waves, temperature profiles and benthic conditions around sea-cage and coastal sites — regulator-grade data.

  • ADCP current profilers and wave / met stations
  • Under-cage video and sediment sampling for benthic reports
  • Harmful algal bloom (HAB) early-warning integration
  • Data packages formatted for regulator submission

Control loops & SCADA

Turning telemetry into automated actions — dosing, aeration, oxygenation, pumping, valve sequencing.

  • PLC / SCADA integration with role-based access
  • PID control on oxygen, pH, temperature, water exchange
  • Alarm hierarchies with SMS / app escalation paths
  • Full event / audit log for insurance and traceability

Remote monitoring & IoT gateways

4G / satellite / LoRa gateways that keep offshore, remote and off-grid sites visible 24/7.

  • Cloud dashboards for multi-site operators
  • Edge buffering during connectivity loss
  • Mobile alarms on excursions, thresholds and equipment health
  • API integration with feed, energy and traceability systems

Calibration, validation & QA

Because sensors that drift silently are worse than no sensors at all.

  • Documented calibration intervals per sensor and site
  • Spare-sensor swap program to keep uptime > 99%
  • Traceable reference standards and calibration certificates
  • Vendor-neutral SOPs so lock-in is never an option

Oxygen Requirement Calculator

Dissolved oxygen (DO) demand scales with biomass, species and water temperature. Aeration, LRP oxygen cones and pure-O₂ injection for RAS or intensive shrimp ponds must exceed peak demand — typically 2–4 hours after feeding — plus a 50% safety margin for warm-water events and power failure recovery.

Hourly O₂ demand
1.75 kg/hr
Design for 2.63 kg/hr (50% margin)
Daily O₂ demand
42 kg/day

Water Exchange Calculator

Daily water exchange controls waste dilution, nitrogen load and overall water-quality stability. Recirculating aquaculture (RAS) turns the full system volume over 4–24 times per day through mechanical and biological water treatment; earthen ponds exchange 5–20% per day; shrimp biofloc systems often run near zero exchange.

Daily exchange
50 m³/day
Pump flow required
2.08 m³/hr
35 L/min

Biofilter Sizing Calculator

Biofilter capacity in a RAS is driven by daily feed load and the ammonia produced per kg of feed (~30 g TAN / kg feed at 45% protein). Media volume is sized to the nitrification rate of the chosen biomedia (typically 0.3–0.7 g TAN / m² / day, or 150–400 g TAN / m³ media / day for K1/K3).

Media volume required
24 m³
24,000 liters MBBR media
Daily TAN load
6 kg/day
Drum-filter flow
500 m³/hr

Stocking Density Calculator

Stocking density (kg per m³ of water) is the single biggest driver of oxygen risk, disease pressure and water-treatment load. RAS tolerates the highest density; ponds and cages the lowest. Overstocking crashes dissolved oxygen before it shows in growth data.

Density
10 kg/m³
Target: 60–120 kg/m³
Status
Under-stocked

Common mistakes we catch at RFQ stage

  • Single DO probe per tank — one drift event and the entire alarm system is blind
  • No cross-validation SOP — sensors silently drift and no one notices until mortality spikes
  • SCADA that alarms but doesn't act — no automated dosing or oxygenation fallback
  • IoT gateway with no edge buffering — connectivity drop = full data loss
  • Sensor selection tied to one vendor stack — every future upgrade becomes a lock-in negotiation
  • No calibration budget in OPEX — the system works on day 1, degrades silently by month 6
