This Scottish company is a joint venture between a marine physicist and an experienced aquaculturist and their focus is on exploiting the potential for physical stimuli to manage farmed fish health challenges. Research is targeted at developing innovative solutions to five key business critical fish welfare challenges. Projects are based on the underwater use of physical stimuli to protect farmed fish health.
The company are looking for a partner to manufacture and provide in service support for devices in various aquaculture markets.
The lead project is anticipated to reach TRL7 by end of June 2019. The company therefore requires a manufacturing partner to transfer their research into a commercially viable product. A product that is suitable for the provision of routine veterinary health interventions to protect the welfare of large populations of farmed salmon.
The commercial product requires an acoustic source to create a specific sound pressure field (frequency and amplitude varying with time) in a suitable volume of water containing fish, such volume to be a maximum of 10,000 m3.
It is anticipated that the acoustic source will be an array of transducers or active hydrophones configured to act as a wide beam angle sound source transmitting acoustic frequencies into water. The array will consist of either a number of transducers or active hydrophones either angled to create a wide beam angle, or will be beam formed to create a wide-angle sound source.
The sound will have a significant sound pressure level and field strengths of 160dB-240dB re 1uPa1m are predicted. Initially acoustic frequencies (1kHz-20kHz) are of interest but further work extending into the low ultrasound frequencies (20kHz -100kHz) are predicted. The sound source will have a 100% duty cycle rating for periods up to 30 minutes. The sound source will be immersed in water (either seawater or freshwater) and all cables and connections must be suitable for regular marine use.
A long term commercial agreement with technical assistance is sought.
