Need

In intensive aquaculture systems oxygen supplementation is necessary to prevent hypoxia; however, oversupply can hyper-saturate systems causing gas bubble disease. Oxygenation in aquaculture, fish holding and transport systems using standard technologies is extremely inefficient; standard oxygen transfer efficiencies (SOTE) are estimated at between 2 and 6% per m submergence for coarse and fine bubble diffusers, respectively, at standard conditions of 0 ppt salinity and 20 °C. Advances in the efficiency of gas–liquid phase processes has seen the emergence of nanobubble technologies producing ultrafine bubbles (⌀

Objectives

1. To demonstrate the efficacy of nanobubble technology for use in finfish aquaculture by:i) assessing the health, growth and feed conversion efficiencies of fish cultured in a recirculating aquaculture system at different temperatures, salinities and stocking densities exposed to nanobubblesii) determining the effect of nanobubble oxygenation on waste water treatment efficiencies in a recirculating aquaculture system.iii) providing a preliminary cost benefit analysis on the implementation of nanobubble aeration to an aquaculture system
