Overfishing ‘destabilizing’ Black Sea, invasive jellyfish blooming

in fish scarce waters 9Overfishing to meet their lucrative markets across the boundaries has always disrupted food chain of the seas. This is no new phenomena worrying scientists and conveniently overlooked by traders.

But, the consequences of overfishing have already left a burn at the Black Sea. With the collapse of fish stocks here — falling to over-fishing — the sea’s food chain has been disturbed.

This in turn triggered a “regime shift” allowing a level of devastation among the sea lives — a species of invasive jellyfish has bloomed.

The solution? Perhaps nothing!

Curbing fishing will not be enough for returning the habitat to a stable state. It is control on pollution and biodiversity that are needed to be adopted, the conservationists warn.

Georgi Daskalov from the UK’s Centre for Environment, Fisheries and Aquaculture Science explained,

Ecosystems exist in a dynamic balance of predator and prey.

Changing relationships within the food web, such as removing top predators through fishing, can tip the scales and lead to large-scale changes in ecosystem make-up, scientifically referred to as regime shifts.

Surprisingly, over the 50-year period, the population trends of the sea’s fish and plankton are said to have experienced two major shifts!

Even such a “jolting scenario” may not be able to move over the economy-building lucrative over-fishing, made indiscriminately. What are the environmental watchdogs doing, with such unjust damage to the environment happening right under their nose?

Will the other regions in the world suffering a similar problem learn from such gruesome aftereffects? — Or will move to the commands of the big industrial guns?
