CANBERRA (Xinhua) -- Climate change is driving a collapse of the marine food chain, an Australian study published by the University of Adelaide on Wednesday has found.

The study found that rising ocean temperatures was reducing the flow of energy from algae at the bottom of the chain to herbivores or predators, harming commercial fish stocks.

Researchers constructed 12 large 1,600 litre fish tanks to mimic conditions in a warming ocean caused by greenhouse gas emissions and introduced a range of species to the tanks including algae, fish, snails, sponges and shrimp.

The small ecosystem was maintained under future climate conditions for six months, during which time the growth, survival and productivity of every species was tracked.
