Aquaculture Industry + Power Generation Industry

July 3rd, 2009 by Hayley

Nik, a member of the finfish.org community, is interested in aquaculture from an energy point of view.  He has spent a lot of time and effort in the cooling tower and condenser areas within power.

Nik writes:

There are vast amounts of low temperature energy ie (45 – 50 C) that is rejected to the atmosphere through evaporation of water.  I was reading a study about fish and prawn growth rates (particularly Kuruma prawns) adversely affected by lower temperature waters.

I would like to know if anyone had considered coupling the two industries on a large scale (ie 100 ha size farms) and if so, with what result?  The concept is not exactly new, European countries have been utilising the “waste heat” for district heating of dwellings… But there is not much call for district heating in Australia especially since the power stations are located in rural areas.

So I’ve been looking for an industry in Australia that could utilise large amounts of “waste heat” in rural areas.  I think that a primary industry on a large enough scale could warrant some further investigation.  A brief investigation was done during a study for solar thermal desalination of the Murray.

Current methods of powering aquacultures

February 16th, 2009 by Vassos

I’m interested in the current methods/equipment that aquaculture owners use to power up their businesses.I have found an article by J. David Bankston, Jr., and Fred Eugene Baker that illustrates the basic methods plus their economic impact. My main concern is how are they currently doing  it e.g. electric motors, internal combustion engines, solar, wind….etc. If anyone can guide me towards articles or websites I’ll appreciate it, because I’m curently thinking on creating one and I’m more concern about these alternatives


Aquaculture Power Generation via Wave Energy

October 28th, 2008 by Andrew

Wave energy is a form of renewable energy source generated by the ocean’s wave, and potentially could be used to generate electricity, as well as the free source of energy used for water purification.

The World Energy Council estimated that around 2 terawatts (2 million megawatts) could be produced from the oceans via wave power. This is figure is two times higher than the current world electricity production. It is also estimated that 1 million gigawatt hours of wave energy hits Australian shores annually [1]. Note that wave power is to be differentiated with tidal power [2], which is based on the tidal movement due to relative motion of moon and earth .

Wave energy generation is suitable to be implemented Western Australia, since our wave current is quite strong. Other part of Australia that has strong wave current is Tasmania and eastern side of South Australia. This is quite interesting, since most of the aquaculture industry are located around this area. 

There is one Western Australian company called CETO, which is having the technology to harvest the energy from the ocean’s wave for water purification and power generation.

Perhaps, CETO technology could be used to help aquaculture industry.
