As wild fishery populations stagnate, the aquaculture industry has emerged as an important means of providing protein to an ever expanding population, over the last few decades. Aquaculture relates to the farming of a variety of aquatic species in marine, brackish and freshwater environments. Commercial species range from finfish to shellfish to algae and are produced via a number of different production methods. One of the key issues regarding the sustainability of aquaculture, is the issue of water quality.
The importance of water quality monitoring in aquaculture is two-fold. Good water quality is important for ensuring the effective production of healthy fish that are fit for human consumption, whilst the environmental impacts of the production process itself need to be carefully monitored, too.
Real-time monitoring of water quality parameters such as algal biomass, cyanobacteria and pollution is becoming increasingly favoured over traditional methods of sampling and laboratory analysis due to the high cost and labour required.

CTG provides a number of sensors for real-time water quality monitoring for parameters such as chlorophyll a, blue-green algae, turbidity, CDOM and tryptophan. Our current range of sensors are detailed below:
V-Lux Multi-paramter Fuorometer – New multi-parameter fluorometer available in a number of configurations to provide high quality in situ detection of either Algae, Aromatic Hydrocarbons or Tryptophan-like fluorescence. This instrument automatically corrects readings for turbidity and absorbance.
UniLux Dye Tracing Fluorometer – Rhodamine and fluorescein sensors for dye-tracing studies. Ideal for monitoring water flow in open cage systems.
FastOcean – Our Fast Repetition Rate fluorometers (FRRf) can be used for assessing algal health and primary production. These instruments are ideal for characterising water body productivity and can be used for site selection/ feasibility studies.

FastOcean APD System
Acoustic range – CTG offer a range of acoustic transducers and hydrophones that can be incorporated into a number of systems. One example of this is for the use of marine mammal deterrents.
