   According to Aquafeed, Goudey conducted the tests at Snapperfarm, Inc., an offshore fish farm that has been growing cobia in submerged cages for five years. The spherical cage, developed by Ocean Farm Technologies, Inc. of Searsmont, Maine, was an Aquapod with a capacity of 3,250 m3.

   That was certainly an interesting presentation and it is always encouraging to see attention and curiosity surrounding open ocean fish farms and the pens used for them. It is worth emphasizing that only Ocean Farm Technologies’ Aquapod and Ocean Spar’s Sea Station have been built and deployed in North America. Furthermore, Ocean Farm Technologies has installed additional Aquapods beyond the ones mentioned in the presentation and continues to do so on a global scale.

   The technology and feasibility to raise fish in high energy offshore conditions continues to advance on a daily basis. We are optimistic that this type of aquaculture production will play an ever larger role in the industry as producers and the public embrace this more sustainable approach to fish farming.

   Thanks for the clarification. Do you think you could provide more information on latest developments and in the feasibility you mentioned. I posted information on the presentation above because it specifically mentions cost comparisons (per cubic metre).

   Do you think you could provide some up to date information on the costs of the aquapod cages and how that compares with a near shore cage of similar size. I think we all understand that the deep ocean cages are more expensive, but it would be interesting to quantify the difference.

   That is a lot to cover but I’ll try and touch on everything briefly.

   The long term success of offshore operations will require successful automation of many standard operating procedures to reduce overall operating costs, minimize labor, improve safety and further reduce environmental impacts. Of course all of this will improve the overall feasibility of offshore production. Ocean Farm Technologies (OFT) is actively working on and testing means to realize some of these long term goals. One example of this would be automation of pen rotation. This will allow cage cleaning/surface drying to be conducted on a schedule with minimal user input required, thereby freeing many man hours and ensuring fouling is kept to a minimum.

   Without getting into considerable specifics, it can be said that at this point in time that the initial costs of offshore submersible pens are higher in general than near shore floating pens. Yet, the important thing to understand is that the lifetime costs of a submersible offshore pen when compared to floating net pens is very comparable. The labor and cost to clean, repair and remove netting from floating cages in conjunction with the risk for escapes and damage from storms greatly escalate the long term costs of near shore pens. It is also valuable to consider the reduced disease opportunity and optimized growing conditions that crops will benefit from in open ocean environments when looking at costs.

   Pricing is variable depending on many different specific factors but OFT is happy to discuss these with interested parties and help develop reasonable cost estimates.
