Aidan,

Your awareness of reality of the state of the marine environment and ocean ecosystems is testimony to media boycott and failure to investigate and report evidence of the situation in news, such as why Australia is now having to import over 70 percent of fish annually.

I can claim overfishing is not to blame because I have evidence of substance to prove it.

Yes nutrient is in short supply out to sea in open ocean generally in the southern hemisphere but no so in the northern hemisphere.
e.g. Take a look at algae feeding on nutrient in the northern Atlantic.

Coral has evolved in balanced nutrient conditions. Coral almost everywhere right now is impacted by algae. I see it. I am a diver. I study dying and dead coral. I have photo data evidence, dates and time.
I wish OLO provided for photos.

Open ocean generally is almost almost bare of food. If you think otherwise, ask yourself where that food comes from, where does it breed, where can that food be seen?

If you think there are too few big fish and therefore lots of small fish, where are those small fish?
Small fish are even imported into Australia to feed aquaculture. LOL

Truth is vast quantities of small fish to feed ocean fish comes from estuaries and bays and lagoons.
The small species of fish swim out to sea to become food for bigger fish and animals such as birds and whales.

Most estuary and bay and lagoon seagrass is long dead and gone due to nutrient overload feeding over-abundance of algae epiphyte growth that reduces sunlight and essential photosynthesis.

The 1990's SOMER report found 50 percent of seagrass lost from the NSW coast.
Over 95 percent of seagrass has been lost from the Nerang River (Qld) estuary alone, Moreton Bay has massive loss in areal coverage and especially density.

M/s Hillary Clinton best lookout if US President.
World war must be avoided because there is no longer enough worldwide seafood to HELP sustain over 7 billion people.
