Due to continued growth, AQ1 Systems has moved its' Head Office in Tasmania to Derwent Park in January 2017. If you experience any issues contacting our staff during the move please send an email to firstname.lastname@example.org and we will respond as quickly as possible.
AQ1 is pleased to announce the introduction of aeration control to the SF200 Sound Feeding system to complement existing feeding control and environmental monitoring.
The aerator control is designed to actively stop aeration when Dissolved Oxygen reading rises above a user set value (usually in the morning) and then switch aeration back on when DO falls below another preset value in the evening.
There are two outputs on each SF200 Controller to switch 2 banks of aerators on and off independently based on different DO settings.
AQ1 recently completed a global productivity survey which showed that shrimp farmers using the Sound Feeding System recorded average growth increases of 23%, FCR reduction of 20% and a 13% better survival. The survey was completed on an anonymous basis by 32 farmers from 9 countries growing 4 different species of shrimp and in ponds ranging between 0.05ha and 24ha. Further details are in the October edition of the Shrimp Farmers Technology Newsletter. Contact us at email@example.com for further details.
After becoming the industry standard for sizing and counting Bluefin Tuna, AQ1 has been developing new algorithms (models) for the AM100 System that enables our clients to accurately measure and size a variety of other species including kingfish, amberjack, red sea bream, cobia, atlantic salmon and barramundi. The AM100 system is set up so customers can create their own measurement to weight models or work together with AQ1 to develop them.
A research study was carried out by Napaumpaiporn et. al. (2013) from Kasetsart University, to compare the shrimp performance and effect on water quality of 3 different feeding techniques, at a commercial farm in Thailand. The Sound Feeding System (SF200), which uses passive acoustic sensing to control feeding, was compared to hand-feeding and to a simple timer operated feed dispenser with feed trays. After about 100 DOC the results showed that ponds with the Sound Feeding System had produced 13% better FCR, 33% faster growth, a larger biomass, larger shrimp as well as better water quality in the pond (lower nitrogen/ammonia). The excellent result was directly related to optimal temporal and spatial feeding by the SF200. The results highlight the benefits of using the sound of shrimp eating to control feeding.

Director of Technology at AQ1, Dr David Rasch, explains the major developments incorporated in the new Sound Feeding System (SF200) that is being released this month. “It is has always been the AQ1 plan to develop a very smart feeding control algorithm to cover a full range of shrimp farming configurations. The original SF200 system incorporated the basic features needed to control feeding by analyzing shrimp feeding sounds and was deployed on 5 species of shrimp in 7 countries on 10ha ponds at 10 PL/m² through to 0.1ha ponds with 450 PL/m².”
“The data gathered from these deployments gave AQ1 a unique insight as to how the acoustic feeding control settings in the SF200 could become self adjusting to produce optimal feeding control in all circumstances and throughout the production cycle. We call the systems ability to continuously learn the “Sonic” control algorithm and it is the result of 3 years of research.”
“In addition to self learning, the SF200 system now has the ability to manage feeding on multiple ponds from a single controller, which reduces price, monitor DO and create environmental alarms which turn feeding off automatically. The system can also identify when a feeder is empty or blocked and turn off when a maximum daily feed target (kg) is reached.”
“With the SF200 PC software the emphasis has been on providing users with a rapid understanding of shrimp feeding activity and feeding rate and to compare daily feed intake over time”
AQ1 will be attending the following conferences:
AQ1's Sound Feeding System (SF200) is now being used for feeding control and environmental monitoring on large extensive ponds 8-10ha at 15-25PLs/m². Director Peter Blyth said historically the SF200 has been deployed on monodon and vannamei in intensive ponds ranging from 0.4ha to 1.5ha. But large ponds are a totally different environment and we are seeing some very interesting feeding behaviour and environmental trends. Data indicates that shrimp move in and out of the the feeding zone under the feeder and that they move away from the feeding zone to digest as there is no build up of detritus under the feeder.
AQ1 has released the latest research results on when and where black tiger prawns eat in commercial ponds in its shrimp farming newsletter. Wind direction and water temperature were major factors and the "Sound Feeding System" SF200 recorded it all. An FCR of 1.42 was recorded on prawns with an average harvest size of 39.7 grams.

In the first commercial test of AQ1's Sound Feeding technology (SF200) on black tiger prawn (P. monodon) the SF200 has recorded what may be a world record production equivalent to 22.7t /ha in a single crop. The trial was undertaken at Gold Coast Marine Aquaculture on 9th generation domesticated monodon in the 2009/10 growing season. Expansion of the trials will occur in the 2010/11 growing season and extend to other tiger prawn and white shrimp farmers.
In projects on Southern Bluefin Tuna and Kingfish in South Australia, AQ1 has enhanced its video based feeding control systems (AQTV) to enable feeding control over the internet from a PC or PDA. This reduces the farmers operating costs by minimising the time support vessels spend on site feeding the Tuna.
