As I started to write my talk for the climate change stream at the aquaculture conference, I wondered whether that was the right question and changed it to ask “is your business viable in the face of climate variability?” Aquaculture is very vulnerable to weather, energy and water availability and there is a huge up front investment involved
This is a question that a lot of businesses would benefit from asking even if they are not as vulnerable as aquaculture.
There are two issues that we should think about when discussing climate change and these are:
- How to prevent it getting worse
- How to cope with the consequences
Individually we can’t do much about the prevention and cure, so we need to manage our own consequences.
It is time to ignore what anyone believes, even though the science is very strong and there is only uncertainty around how fast it is happening and how severe it will be. Meantime:.......................
Last week I listened to a talk by barramundi grower, who was severely hit by category 5 cyclone Larry in North Queensland.
The start of this story is about cyclones but read on for floods, bushfires and even long term power failure. Could your business cope?
One of the really interesting talks at the aquaculture conference last week was by Professor Gustaaf Hallegraeff.
While the excess carbon dioxide emissions, increases phytoplankton the species distribution may change and that could bring some unexpected consequences including changes in distribution of species and increases in the number of toxic algal species...............
If Scotland stopped using oil, it would still have plenty of energy. A new report shows that wind, wave and tidal energy could power the country seven times over within four decades. Not a lot is being used at the moment and it would, hopefully will, require an estimated £4bn investment per year.
This would however, generate £14 billion profit from electricity sales by 2050 and provide about 60,000 jobs in Scotland, according to the report by the Offshore Valuation Group, a coalition of government and industry organisations. It would also strengthen the case for Scotland becoming a major exporter of renewable energy to Europe.
There are some slow but steady changes putting fish and especially freshwater fish at risk and these are cause by a combination of climate change and agricultural practices. Yesterday I listened to fascinating talk by fish vet Matt Landos and I am passing much of this on.
In the Murray River, decreased water is causing an increase in acid sulphate soils which release sulphuric acid into the river when it rains. And the change in pH causes and increase in fungal disease and puts them much more at risk of a range of fish health issues............
The world human population is growing so fast that by 2030 it is predicted that word food production must increase by 50%. This is not going to happen by growth of plant and animal production. It is certainly not going to happen from increased wild catch fishing as these stocks are already decreasing. We must rely on aquaculture.
My comment here is that this is further reason NOT to allow the use of food to produce biofuels.
The good news is that fish convert plant matter into animal protein very much more efficiently than birds and other land animals. ...........
Victorian DPI are looking at the potential for aquaculture to become an extra use for the same water on the same farm and also add an extra income stream to that farm.
67% of Australian water is used by agriculture and 70% of that is in the Murray Darling Basin. At present this water is only used once a the Primary Industries department is looking to use some of the large private water dams for aquaculture, their thinking being that if any nutrients are added to the water, it can be used by crops as the water is re-used........
BST Oyster Supplies from Cowell in South Australia is the centre for innovation in this industry. First they developed the adjustable long-line growing system and now they have a new oyster basket which can be completely recycled, the Eyre Peninsula Tribune reports.
Eyre Peninsula is remote and the people have developed an independent and innovative approach to all their activities.....
p.s. Most of my readers tell me this newsletter is a great way of getting up to date information easily but if you are really snowed under by lots of emails from other sources you can chose to keep in touch by emailling jean@enviroaction.com.au and go onto the monthly list.
