Hi,
Really haven't been doing much of late. Had the usual flare up of chronic fatigue (worse over summer) so my motivation went w-a-a-ay down. The auto syphon on my system malfunctioned and it took me two months to get it sorted out. Fish pond is still clear though.

Just retuned from a couple of weeks tour of Tassie. Had a great time and recharged the old batteries.

Murray is presently making a 585 litre grow tank for me. I will couple it to a 1,000 litre poly tank for a trial with the edible species. If all works out well I will go larger.

Still waiting for rain so I can get my tanks filled and use them for the aquaponics and topping up etc.

Just had a read of Earhtbound's Backyard Aquaponics book. Good stuff in there. Well done Joel.

I've got bees everywhere all the time - natives, and introduced ones. That worries me MC and AM. To me that is an indication that some prick not too far from you likes their poisons.

there is a hive of natives on the far side of the school campus... but they never venture over this way :? ... to be fare, I have not had much in the way of flowering plants here so that is why I have never worried about the bee thing (but then again, I had never thought about the fact that somebody may be poisoning them :? :? :?

By poisoning - I don't mean delberately. It's just that when people use incecticides on their gardens, they can kill the bees.

:?
I have seen a lot of 'spraying' go on in my close - never even gave it another thought...
I only ever use poisons when there is an ant invasion in our home - I don't like poisons much :?

A friend mentioned this to me the other day, "have you heard about the bees disapearing in the U.S."

Just did a quick google for bees in U.S.

And it's not good.... This is pretty damn scary stuff, such a simple thing, who would have thought.. It's fine being able to grow your food crops, but if there are no bees there to polinate, then you get no fruits or seeds of nuts..

Quote:
Feb. 5, 2007 — Something is wiping out honey bees across North America and a team of researchers is rushing to find out what it is.

What’s being called Colony Collapse Disorder (CCD) has now been seen in Pennsylvania, North Carolina, Florida, Georgia and way out in California. Some bee keepers have lost up to 80 percent of their colonies to the mysterious disorder.

Vanishing bees threaten US crops
By Matt Wells
BBC News, Florida, USA

It is officially called Colony Collapse Disorder, but a more pithy way of describing it would be Vanishing Bee Syndrome.

Bees are driven around Florida to help pollinate early crops

All over America, beekeepers are opening up their hives in preparation for the spring pollination season, only to find that their bees are dead or have disappeared.

Nobody, so far, knows why.

The sad mystery surrounding the humble honeybee - which is a vital component in $14bn-worth of US agriculture - is beginning to worry even the highest strata of the political class in Washington.



Quote:
Albert Einstein once predicted that if bees were to disappear, man would follow only a few years later.

That hypothesis could soon be put to the test, as a mysterious condition that has wiped half of the honey bee population the United States over the last 35 years appears to be repeating itself in Europe.

Experts are at a loss to explain the fall in honey bee populations in America, with fears of that a new disease, the effects of pollution or the increased use of pesticides could be to blame for "colony collapse disorder". From 1971 to 2006 approximately one half of the US honey bee colonies have vanished.

Now in Spain, hundreds of thousands of colonies have been lost and beekeepers in northern Croatia estimated that five million bees had died in just 48 hours this week. In Poland, the Swietokrzyskie beekeeper association has estimated that up to 40 per cent of bees were wiped out last year. Greece, Switzerland, Italy and Portugal have also reported heavy losses.

The depopulation of bees could have a huge impact on the environment, which is reliant on the insects for pollination. If taken to the extreme, crops, fodder - and therefore livestock - could die off if there are no pollinating insects left. In France in 2004, the government banned the pesticide Fipronil after beekeepers in the south-west blamed it for huge losses of hives. The manufacturers denied their products were harmful to bees. Polish beekeeper associations claimed that the losses in their country could be connected to cheap sugar substitutes used in mass honey production.

However, experts at the largest honey bee health company in the world, Vita, based in Basingstoke, said the cause was still unknown, and therefore neither was the cure.

The company's technical director, Dr Max Watkins, said: "If it turns out to be a disease we will probably find a cure. But if it turns out to be something different, like environmental pollution, then I do not know what can be done.

"At the moment, all we know is colonies are dying and we simply don't know why. It could be a new disease or a combination of factors. And of course it could turn out what we are seeing here in Europe is different to what has been reported in America, although at the moment they look very, very similar."

Dennis van Engelsdorp, of the Pennsylvania Department of Agriculture, said: "Preliminary work has identified several likely factors that could be causing or contributing to CCD. Among them are mites and associated diseases, some unknown pathogenic disease and pesticide contamination or poisoning."

Initial studies of dying colonies in America revealed a large number of disease organisms present, with no one disease being identified as the culprit, van Engelsdorp added.

German bee expert Professor Joergen Tautz from Wurzburg University said: "Bees are vital to bio diversity. There are 130,000 plants for example for which bees are essential to pollination, from melons to pumpkins, raspberries and all kind of fruit trees - as well as animal fodder - like clover.

"Bees are more important than poultry in terms of human nutrition. Bees from one hive can visit a million flowers within a 400 square kilometre area in just one day.

"It is not a sudden problem, I has been happening for a few years now. Five years ago in Germany there were a million hives, now there are less than 800,000. If that continues there will eventually be no bees."

"Bees are not only working for our welfare, they are also perfect indicators of the state of the environment. We should take note."

Yes, we do have bee fatality problems. Mites have been blamed, but also various unknowns like the poisoning of our environment with insecticides and other pollutants. It's a bit worrisome. People don't realize how critical bees are to our food supply.

C1, But resistant to what? The problem is that we are unsure what is killing them. Lots of studying needed, but as soon as possible!

Wow, knew about the importance of bees, even knew about them being utilised inbig hydro igloos, even heard about using blue banded bees here in OZ.

Hadn't heard about them being decimated in the US......:shock:

I stand corrected after researching the topic. I was under the impression our native honey bees were not on the 'to eat' list for the mite that is doing all the sucking.
wrong they are!
