Marine and Aquaculture

Marine, coastal and aquaculture monitoring is a growing area of activity for Flux Enviro, building on our established expertise in water-quality instrumentation, environmental monitoring and remote data acquisition.

We provide specialist equipment and monitoring solutions for freshwater and marine aquaculture, coastal and estuarine monitoring, environmental assessment and research, supporting everything from routine field measurements and water sampling through to water-column profiling, continuous monitoring and remotely connected systems.

Aquaculture monitoring can involve routine or continuous measurement of dissolved oxygen, temperature, pH, conductivity, salinity, turbidity and other water-quality parameters, helping operators understand changing environmental conditions and identify conditions that may affect stock, production or wider environmental performance.

Marine and coastal environments can introduce additional measurement challenges including salinity, biofouling, tidal variation, changing water depth, currents, difficult access and exposed deployment locations. Equipment and monitoring systems therefore need to be selected around both the required measurements and the conditions in which they will operate.

Flux Enviro can support applications ranging from handheld field measurement and discrete sampling through to CTD profiling, multiparameter sondes, permanent monitoring stations and remotely connected sensor networks, with equipment available for both purchase and rental.

Monitoring requirements can range from routine spot measurements to permanently deployed, remotely connected systems. The appropriate approach depends on the monitoring objective, required parameters, spatial coverage, measurement frequency and deployment environment.

Aquaculture Monitoring

Maintaining suitable water conditions is fundamental to fish health, stock performance and successful aquaculture operations. Monitoring requirements vary between freshwater and marine production systems, but commonly centre on understanding how key water-quality parameters change throughout the day, between seasons and in response to operational or environmental conditions.

Flux Enviro supports monitoring within freshwater and marine aquaculture facilities, hatcheries, tanks, raceways, ponds and open-water production sites, with instrumentation for:

• Dissolved oxygen and temperature

• pH

• Oxidation-reduction potential (ORP)

• Conductivity and salinity

• Ammonium

• Turbidity

• Chlorophyll and other biological indicators

• Continuous multiparameter water-quality monitoring

• Remote data access and configurable alarms

For routine operational checks, portable instruments such as YSI ProSolo and ProDSS meters provide rapid measurements across production areas. Where conditions need to be monitored continuously, fixed sensors and YSI EXO multiparameter sondes can provide higher-frequency data and identify changes that may not be captured by periodic manual measurements.

Continuous monitoring can be particularly valuable for parameters such as dissolved oxygen and temperature, where conditions can change relatively quickly and potentially affect stock before the next scheduled manual measurement.

Monitoring systems can also be connected to telemetry platforms, allowing operators to view current and historical conditions remotely and configure alerts when selected parameters move outside defined limits.

Water Sampling & Profiling

Discrete sampling and water-column profiling are important across aquaculture, environmental assessment and marine research, particularly where the objective is to investigate spatial variation, depth-related changes or conditions across a wider water body.

Flux Enviro provides equipment for:

• Surface and depth-specific water sampling

• Water-column profiling

• CTD measurement

• Multiparameter profiling

• Spot water-quality measurement

Portable instrumentation allows water-quality measurements to be collected rapidly across multiple locations, supporting routine aquaculture checks, environmental surveys, verification and investigative monitoring.

CTD profilers can be used to investigate changes in conductivity/salinity, temperature and depth, providing rapid vertical profiles through lakes, reservoirs, estuaries and coastal waters. Multiparameter instrumentation can extend profiling to parameters including dissolved oxygen, pH, turbidity, chlorophyll and other optical measurements, helping identify stratification, mixing, biological activity and changing water-quality conditions with depth.

Discrete sampling can complement in-situ measurements by allowing water samples to be collected from specific locations or depths for subsequent laboratory analysis, enabling field measurements and laboratory datasets to be considered together.

Coastal & Estuarine Monitoring

Coastal and estuarine environments are dynamic systems influenced by tides, freshwater inputs, salinity gradients, weather conditions, biological activity and human pressures. Monitoring programmes may therefore require measurements across multiple locations, depths and environmental conditions.

Flux Enviro provides instrumentation and monitoring solutions for baseline surveys, environmental assessment, research and long-term monitoring, including:

• Water-quality measurement and profiling

• Conductivity, salinity and temperature

• Dissolved oxygen

• Turbidity and suspended-material indicators

• Chlorophyll and biological parameters

• Water sampling

• Continuous multiparameter monitoring

• Meteorological monitoring

Portable instrumentation can support spatial surveys and field campaigns, while fixed sondes and monitoring stations allow changing conditions to be investigated continuously at selected locations.

Longer-term marine deployments require particular consideration of biofouling, tidal range, currents, deployment structures, sensor accessibility and maintenance intervals. Flux Enviro can assist with selecting not only the instrumentation but also the deployment, power, logging and telemetry arrangements required for the monitoring location.

Remote Monitoring & Telemetry

Continuous monitoring becomes significantly more useful when data can be accessed remotely and changing conditions identified without waiting for the next site visit.

Flux Enviro can integrate water-quality and environmental sensors with data logging and telemetry systems for freshwater aquaculture facilities, coastal locations and remote monitoring sites.

Systems can provide:

• Remote access to current and historical measurements

• Automated data transmission

• Configurable alarms and notifications

• Multiple sensors or monitoring locations

• Local data storage alongside telemetry

• Solar or mains-powered operation

Systems can range from a single remotely connected water-quality sonde to multi-parameter monitoring stations, incorporating water quality, meteorological measurements and other environmental sensors.

Flux Enviro can support the complete system including sensor selection, configuration, power, telemetry, enclosures, installation, commissioning and ongoing servicing.

Equipment Rental

Marine, aquaculture and research projects do not always require permanent instrumentation. Short-term surveys, research programmes, baseline assessments and temporary monitoring requirements can often be supported more efficiently using rental equipment.

Flux Enviro maintains specialist rental instrumentation including:

• YSI handheld water-quality meters

• YSI EXO multiparameter sondes

• CTD profilers

• Water samplers

• Water-level and environmental data loggers

• Supporting telemetry and monitoring equipment

Rental equipment can be supplied configured and ready for deployment, with the required cables, accessories and supporting equipment.

This can support anything from an individual sampling campaign or profiling survey through to temporary continuous monitoring, with technical support available throughout the rental period.
