Over Fishing.

Sorry about not posting lately, my Internet at home is really weird! And if no posts opp up in the next few days its because of my Internet light going red again!
As a note before my post, I currently have 8,600 views and the bestest Christmas present I could get would be 10,000 blog views! So please please please share this via twitter, facebook, email it or follow me on my blog to get updates (theres a little 'follow box' in the bar to the right of this post.)

Vright (thats not a spelling mistake its me saying right in an accent.) Today's topic is over fishing, thanks to Miss Lane who sent his though to me.

Also check out the great WWF posters throughout this post.

Perhaps watch this great video before you read this post....

And just as a reference the site this video is at is amazing!

Overfishing is a major issue, especially for the 2million people who get their daily protein from the sea, but what is going to happen when all of these fish are gone? A global fisheries collapse is expected in the next 50 years, and already certain areas are lacking the biodiversity and vital food chains required to function as a unit.

Think about the 175 million sharks that are culled every year, just for their fins. that's 175 million sharks that are no longer managing fish stocks in that area. For those of you who don't really recognise the importance of a shark in the environment, it is like taking the spoon away from the soup bowl and giving you a fork, it doesn't really work. This change to the environment leads to an increase in smaller fish, like sardines, but then these fish are caught and sold in little cans anyway.

More than 85% of fish stocks have already been pushed passed their biological limits. Some experts believe that total fish stocks have declined 90% already.

Some of the causes of over fishing are...
There is a huge lack of reserves. using an example of New Zealand, 30% of our country has been made into reserves. Where as only 0.3% of our mainland coast is reserve land. The land reserves mean many of our species have room to breed and thrive. The lack of marine reserves tells a different story. Take for example of snapper in the Goat Island reserve. Snapper numbers have still not returned to their pre-fished value, this is because snapper need 40 square kms to thrive. Goat Island is only 5.1 square kilometres.

Pirate fishing in which illegal, unrecorded and unregulated fishing occurs.


Many governments still continue to subsidize their fleets, allowing unprofitable operations to subsist, and overfishing to occur. Today’s worldwide fishing fleet is estimated to be up to two and a half times the capacity needed to catch what we actually need.' This excert from

And poor fishing management. current rules and regulations really are not strong enough and out in the middle of no where, who is their to enforce it? And even when they get back to port and are identified as having extra catch, this fish are already dead anyway.

The threats of this practise include Marine life in balance. This is like the sharks mentioned above and large predators like tuna which mean their are smaller fish and an increase in algae life, further disrupting the marine life and the health of reefs.

Over fishing also threatens the small villages which rely of fish for an income and food. What will happen to these villages when fish cant support the inhabitants anymore?

Overfishing is also heavily linked to by catch, another destructive practise in which other species not targeted are caught and then are normally thrown back over board, dead or injured.

Lots of the information and inspiration for this post came from here
