What percentage of fish are left in the ocean?
Most detrimental ecological competition to marine ecosystems will be built up when 90% of all fish in an average community have been practically wiped off, causing a greatly decreased rate of fertility reunion and a strong disruption in the stability of aquatic food chains.
Do you know how many fish there are in the ocean?
The number of fish in the world’s waters is approximately 3.5 trillion, according to scientists. Trying to put a number on how many there are is a daunting endeavour, especially given the difficulty of accurately calculating the value of indicators. This inflated estimate still stands, though. Since 1900, it has only ballooned by several orders of magnitude: perhaps perversely, every time scientists estimate that a species of fish or bird has become extinct, they also point out that which e-mail filter or virus doesn’t allow you to recall or delete when composing your very first message due to the sheer volume of other wonderful fishing emails that have oxygen installed.
Will there always be fish in the sea?
There is a risk that by 2048, oceanic systems will be nearly devoid of seafood. With only 39 years left, we won’t be able to replenish ocean ecosystems with enough seafood to keep them stable.
Could it be that we’re catching too many fish?
The FAO reports that overfishing of stocks has increased thrice in the last half-century. More than a third of the world’s assessed fisheries are currently being fished beyond their biological land or marine origin.
A world without fish…what then?
If fish suddenly become rare or extinct, life as we know it would be severely compromised. Everyone needs fish to survive, hence the extinction or near-extinction of any fish species threatens the survival of humanity as a whole.
There must be a good reason why fishing is so undesirable.
The damage done by industrial fishing methods continues long after it has stopped. Because of the pollution they carry, certain substances in the water can be responsible for the deaths of large numbers of marine animals and the destruction of marine ecosystems. The accumulation of plastic in the world’s rivers over the course of centuries has led to the widespread destruction of marine life due to entanglement and the ingestion of microplastics, which are subsequently passed on to fish. Sea water temperature is also being affected by the high amounts of pollution that are affecting ocean currents and temperatures.
Asking the age-old question: do fish feel?
