Canberra, Australia (4E) – Overfishing is threatening tuna supplies both in Australia and Indonesia.
Supplies of tuna have depleted by 96 percent in the north Pacific Ocean as stocks are exploited and over-fished, according to Al Jazeera News.
One fish that is particularly suffering is the blue fin tuna according to the report.
In Indonesia meanwhile, fishermen are using explosives to catch fish.
Demand for fish has increased nearly three times by 2010, from the 1970 average of 40 million tons the world consumed.
The government has introduced marine protected areas where fishing is limited to make sure fish populations will grow back.
