Envirofinfish.org was implemented due to a lack of available information on the environmental management of aquaculture and will operate in the same way as finfish.org.  You can access this site here or by clicking the envirofinfish.org icon on the sidebar.

According to the press release on their website, the innovation will revolutionise production and harvest of cod and potentially other marine species such as sea bass and sturgeon.  

By fully controlling the environment in which the cod are raised, including daylight sequences and and tide movements, healthy, parasite and disease free fish are produced with a growth rate three times faster than wild fish.  DIOBAS note they are not seeking to grow and supply fish to the market, instead viewing themselves as technology providers.

The freshwater system can be operated in a variety of sizes, the smallest producing 100 plus tonnes of cod, with the initial crop harvestable within two years.  The fully enclosed system produces virtually nil waste output, as bacterial content is absorbed by organisms present in a connected tank.

Could this be a solution to the worlds declining marine fishstocks?

In the  SELFDOTT project (From capture based to SELF-sustained aquaculture and Domestication of bluefin tuna, Thunnus thynnus), daily spawnings consisting of  more than 140 million eggs have been obtained at the project´s installations in Cartagena (Spain), which are managed by the Tuna Graso company, with a maximum of 34 million eggs on Friday 3rd July, a figure which has never been achieved in previous projects.

The second project  ALLOTUNA based in Calabria and funded by the region Puglia at the Mare Nostrum facilities were able to produce up to a total of 46 million eggs over a number of days and  reproduce for a second year running viable quantities of eggs for international hatcheries.

The numerous international hatcheries based in France, Spain, Malta, Crete and Israel are all now concentrating on the developing larvae.  The international consortia of scientists used techniques from a previous EU funded project REPRODOTT to make this breakthrough.

This is  a tremendous boost for the European  Union funded projects  to show that “eggs on demand “ may   be a sustainable pathway for aquaculture  and help  the conservation  of the dwindling tuna stocks in the future.

On the 7th of July in Spain  excess eggs were returned to the sea and this symbolic historical act , when for the first time living Tuna eggs have been returned to the sea from breeding fish in captivity marks a small step on the road to recovery. The validity of such restocking programmes is hard to assess but every little could help together with other ecologically sustainable management concepts for wild and aquaculture stocks in the future.

These Cones are used to inexpensively and simply build a compact system for efficiently holding live fish and aquatic animals.

Rebecca has written to finfish.org as she is conducting a project on the size and scope of the Austrlalian Barramundi  market.

Rebecca is looking for information on the following:

• Current product available (by product – wild v farmed, fillets v whole fish etc);
• Competitive context (suppliers, imports etc);
• Size of market in each state;
• Current supply chains;
• Current quality systems;
• Marketing strategies.

If you have information on any of the above, or could point Rebecca in the direction of someone who does, please comment on this post.

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.

A new approach has been developed for marine structures may interest readers.

Researchers at North Carolina State University have created a non-toxic “wrinkled” ship hull coating that resisted buildup of troublesome barnacles during 18 months of seawater tests. Without wrinkles, an identical chemical composition of surface resisted fouling for just one month. The wrinkle solution mimics other surfaces that remain foul free such as shark skin.

Further information about the breakthrough is available via this article.
