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

Oxygen demand in intensive fish culture follows feed: the fish need oxygen to digest what they eat. The recirculating aquaculture textbook by Timmons, Ebeling et al. (NRAC Publication 01-002) uses about 0.25 kg of oxygen per kg of feed as a design rule. Enter your daily feed and, if your system designer uses a different figure, change it.

0.25 from Timmons & Ebeling; use your designer's figure if different

Daily O₂ demand
25 kg/day
Average hourly O₂ demand
1.04 kg/hr
Peak demand after feeding is higher than this average — your system designer sets the peak and backup margin.

Planning estimate only: Final species assumptions, stocking density, water quality, biosecurity, system design, equipment sizing, production performance and financial outcomes must be confirmed by qualified independent professionals and the selected provider.

Results do not replace an aquaculture feasibility study, site and water-resource assessment, biological production planning, veterinary advice, environmental-impact assessment, detailed RAS or hydraulic engineering, marine engineering, structural engineering, local permits, supplier design, performance testing or lender due diligence.

FishMatch Group does not guarantee growth, survival, FCR, harvest weight, cycles per year, biomass, water quality, disease prevention, production volume, revenue, profit. Outputs are not legal, financial, engineering, tax or veterinary advice. Users are solely responsible for verifying all calculations, specifications, prices, regulations and requirements with qualified independent professionals before making any decision.

Supplier and manufacturer listings are provided for research, transparency and discovery only. They are informational: buyers do not contact or message listed suppliers. Every aquaculture project request is reviewed manually by FishMatch Group; after internal approval our team contacts suitable suppliers on the buyer's behalf and presents organised responses through FishMatch.

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.

Biofilter Sizing Calculator

Biofilter capacity in a RAS is driven by the ammonia (TAN) the fish excrete from their feed. This uses the standard equation from Timmons & Ebeling (Recirculating Aquaculture Systems): TAN = feed × protein fraction × 0.092. Media volume then depends on the nitrification rate of your chosen media — take that from the media supplier's tested data.

Use the media supplier's tested rate at your temperature

Stocking Density Calculator

Stocking density (kg per m³ of water) drives oxygen risk, disease pressure and water-treatment load. Safe density depends on species, fish size and system, so this calculator only compares your result against published limits from recognised sources — where no published figure exists for a combination, it says so instead of guessing.

Published: 60–120 kg/m³

Other inputs stay fixed; ± ranges are your stress tests, not forecasts or safe operating limits. Bounds are clamped to permitted inputs. Costs are USD examples, not quotes or guaranteed savings.

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

Turn your monitoring spec into a bankable RFQ.

Neutral engineering, confidential sourcing, comparable bids. Buyers never pay.
