Britain's Seabirds Starve

[ColinW]

This is being blamed on global warming because the conservationists are more interested in that than fish stocks. Anyone with any sense could have predicted that you can't take 750 million tons of protein out of an ecosystem year after year without causing serious damage.

Hello Colin

 

The total Danish catches of sand eel in the north sea range from 500,000 to 900,000 tons still the fishery is with in safe biological limits ,

quote from ICES 20001

 

750 million tons, sounds like you've been reading Charles bloody Clover.

 

mind you it shows that ICES know nearly as much.

Oops, that should have said kg. Mind you if you can make quotes from reports 18000 years in the future I can make typos too

Good point

Sorry Colin, but thats just not true.

 

The sandeel stocks fished by the Danes are not the same ones needed by many of the failing seabird colonies. There is no sandeel fishing at St Kilda, very little on the Scottish West Coast, and the Shetland one, small as it was, has ended (FWIW it was shown not to be responsible for the seabird collapses there).

 

The plankton is changing; you don't have to search for conspiracy theories when that it is the case.

 

Its fair enough to discuss just what the taking of a million tonnes of sandeels does to the the fish stocks and sealife of the central north sea but this is extending way beyond that area and sandeel is not one stock.

As I understand it man made polution is only 5% of the total the earth naturally produces, i.e volcanic activities etc.

 

But that 5% is in addition to natures efforts and could be more that enough to tip the scales the wrong way.

 

 

One of the big problems are the complex-hydrocarbons and other molecules that man can produce, which do not occur naturally.

 

Life has not evolved to deal with these compounds that get into the food chain and into the bodies of organisms, causing developmental problems, cancers, and interfering with reproductivity etc

 

The biological effects of many of these compounds are not properly understood, and once created they do not break down in the environment, pervasive and lasting for hundreds of thousands of years.
