Fisheries: an entity engaged in raising or harvesting fish, typically defined in terms of the people involved, species or type of fish, area of water or seabed, method of fishing, class of boats, purpose of the activities, etc.
Aquaculture : the farming of fish, crustaceans, molluscs, aquatic plants, algae, and other organisms. Aquaculture involves cultivating freshwater and saltwater populations under controlled conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish.
The use of scientific instrumentation in the aquaculture industry is growing exceptionally fast. MSI can assist in all areas whether it is monitoring the water quality or visually inspecting the fish. Whether it is testing for ecoli to performing sonar surveys of habitats. The world is quite literally your oyster…
The DeepTrekker ROVs are totally portable. Fitting into either 1 (DTG2) or 2 (DTX2) small transit cases that can be carried by one person, are quick and easy to unpack and start (within minutes) and requiring no external power to operate, these units are an ideal way to operate in remote and pristine areas without having to deploy divers. Options include net repairer, water sampler, mort retrieval, side facing cameras, etc. Models include:
DeepTrekker also make a range of Drop Camera’s that allow clear unobstructive 360° viewing that is easily expanded. The systems can be easily mounted or use purely as a drop system
BioSonics have a range of scientific echosounders that make “seeing” underwater so much easier. This includes:
When you have a fixed structure around, be it a jetty, fish pen or even a vessel, the Radac range of sensors can give you radar based wave information in real-time.
When you need to measure wave and/or current in a remote location near to your farm / lease, then a buoy based solution is best. With the bigger systems, you can add water quality measurements too – all reporting in real-time using radio, GSM or satellite communications. Systems include:
Fixing your equipment is important to ensure it is still there when you return. Being able to recover it too is as important and the EdgeTech range of acoustic releases and pop up buoys allow this.
In column ADCP buoys and floats, complimented by the range of bottom frames means that you can get your instrumentation in the exact place that you need it. Combined with inbuilt release systems (such as EdgeTech’s) means that the entire mooring can be recovered, serviced and redeployed.
Knowing where your assets are when underwater, or at night, requires high intensity and reliable lights such as the Novatech flashers. When the assets are recovered by a 3rd party, be it by a weather event, a trawler or through sabotage, being alerted and being able to track it via satellite gives an increased chance of recovery.
Keeping your sensors clean in a marine environment is always the challenge. Zebra-Tech’s range of wipers allows sensors for Tu, PAR, DO, etc. be physically wiped ensuring that the data you collect is as good as possible. A range of wipers for camera systems is also available ensuring your view is not obscured and service visits by divers can be extended.
