MAGADUS SQUARE TUNA BREEDING HUB

Please read the report below that comes from the PNG newspaper Post Courier and is three years old.

It is a report on the tuna breeding grounds in the Magadus Square of the north coast of Papua New Guinea under threat from deep sea mining.

Poisons from the Marengo and Frieda River mines will pollute the Ramu and Sepik Rivers as was the Fly River poisoned by OK Tedi.

Villagers have the right to be angry. Does this country never learn?

11 Nov 2008 – Tuna breeding ground worries ... last Friday Mr Semri said
of particular concern to him was the Magadus Square-the country's tuna hub.

The report above refers to Mr Semri expressing concern that contamination of tuna will affect the tuna industry and sales in Europe.

Poisons tend to accumulate in the tissues of young fish.

Please read the report we have posted to show the ecological link between the Ramu and Sepik Rivers with the Magadus Square.

The rivers provide the estuarine nurseries for fish that hide among the mangroves and eat the nutrients washed down the rivers and out to sea. 

Small fish come up with the tide and return on the ebb tide. In the Magadus Square, the baby fish and pollutants will follow the currents.

Without the river nutrients, the Magadus Square is dead. Mining will provide poisons, change in temperature and acidity/alkalinity of the water and send large currents of chemical water out to sea.

Small tuna will gather to eat the river nutrients and will often take in a large mass of poisoned water. Fish will die en masse.
