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.

With more and more sea cages in remote sites, farmers are seeking 3G communications to enable them to monitor the environment and control feeding through the AQ300 system. AQ1 recently tested the latest in comms on rainbow trout in sea cages in Finland.
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.
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.
AQ1 Chief Executive Ross Dodd presented the latest developments in ultra sonic waste feed detection in tanks at the International Conference on Recirculating Aquaculture in Virginia, USA. Building on work underatken at the Freshwater Institute in West Virginia, Ross believes that "complete automation of feeding control in tanks based on fish appetite is just around the corner - this presents a change of paradigm to the current methods of feeding control which rely on environmental parameters and fish size and density to estimate fish appetite and feeding rates".
