FISHY UPDATE

quirky-australia posted on Nov 09, 2006 | views: 151 | Tags: Feeding fish on fish does not compute, fishing
More about salmon.
They are farming salmon, commercially, both in Norway's 'clean' water in the fjiords, and in our Tasmania's 'clean' waters.
What do they feed them on? - Fish meal pellets.
 
Large trwlers with virtual vacuum cleaners, scoop up hundreds of tonnes of baby and 'rubbish' fish off the S. american W. Coast. It is dried and ground up into 'fish meal' . Then exported as pellets.
 
It takes about 4kg of fish meal, fed to a growing salmon in a fish farm, to produce a 1kg weight gain.
 
What a stupid world we live in. Those 'immature' fish off S. america were part of the food chain, there, were they not?

    Yup, you're right! Maybe that's why the numbers of fishes in the sea are slowing dwindling. They catch the salmon, fatten them in the farms and sell them off with good prices. Over-fishing, one of the problems of world fisheries today.

    For overall concern.
    Human intervention to our ecosystem really affects everything in the world.
    Our ecosystem has its own balance, an equilibrium.
    As part of it changes, no matter how, it develops itself trying to hold of the balance.
     
    There are some insects that we consider pests and have no contributions in the environment.
    But technically, every species has its vital role in the ecosystem.
    To preserve the balance and continue to exists.
     
    Environment as part of the ecosystem when they are intervened, it can cause climate changes like global warming.
     
    The only species that never ceases in production are us, humans.
    The death rate is not equal to birth rate.
    Hence, as time goes by, the population keeps on increasing, either linear or worst, exponential.
     
    Then what will happen to our world.
    Lots of humans but has no food and water?

    Guess we could predict that... lots of humans but has no food and water. Then there goes 'the survival of the fittest', and slowly the human population would decrease too. Wow, this is critical. Shouldn't we do something about it?
