In 30 years asian-pacific fish will be gone and then we’re next

Turns out there aren’t plenty of fish in the sea.

Recent evidence suggests humans evolved their big brains not on a diet of red meat after all, but on a diet of fish. Yes, fish is a great source of protein for all animals. Yes, unaffected by microplastics, pollutants and heavy metals, fish is good for us, ‘us’ being the ever-increasing human population of 7.6 billion and rising (and let’s face it, fish is no longer safe to eat).

Plenty of marine conservation organisations, such as Sea Shepherd, have been saying for decades that while we allow industrial trawlers and fleets of thousands of unregulated fishing boats to ravage the oceans with trawler nets and insidious ghost nets, fish stocks will collapse and there will be devastating implications for all marine life and human populations that rely on fish as a source of protein. Even some marine conservation orgs hadn’t fully understood the role that overfishing plays in the decimation of the oceans – and its impact on local human populations – and are still not condemning overfishing or advising their relatively affluent members to cut out fish from their diets as an effective way of ending their contribution to the terrifying problem of global overfishing.

Anyone can stop contributing to ending overfishing by not eating fish, wherever you are in the world, and by writing to relevant businesses and governmental departments (and your MP), and by boycotting companies which contribute to global (and local) overfishing.

Ocean acidification is deadly threat to marine life, finds eight-year study

I briefly researched acidification in a corals essays I wrote last year (for which I got a first class mark); this study looks in-depth at the impacts of acidification on marine life.

Some marine creatures may be more resilient to harsher ocean conditions than expected – Linkis.com

So I’m writing an essay about drivers of coral reef bleaching, and reading about acidification and its effects on marine mammals that secrete calcium carbonate, and this new research pops up. Interesting immediate adaptation to cope with lower pH levels in marine environments; although I’m not sure how long-term (and effective) an adaptation it might be. Similarly, some coral species and their symbionts are more tolerant of some drivers of bleaching than others. Again, in the short-term that helps those species, but it’s not clear how far beyond their normal thresholds for CO2, irradiance, thermal stress and acidification they can survive. And then there’s coral diseases… We are pushing the limits, changing environments and testing tolerance thresholds for so much of the world’s wildlife, and not in a good way.

100s of dolphins tortured in Japan in alarming Facebook Live stream

And so the vile, arrogant brutal atrocities in the cove in Taiji, Japan continue, year after year, while the world remains blissfully ignorant of the evil these men do for six months of every year to migrating cetaceans unfortunate enough to swim past this little cove off the southern peninsula of Japan. Money is made, greed is satiated, murderous killing occurs and the world’s precious wildlife is decimated by Japan. When will this be called out and stopped as the heinous, greedy, short-sighted, violent, cruel and unacceptable activity that it is?

Oceana reveals that half of the catches in the Balearic Islands over the last 60 years have not been declared | Oceana Europe

Oceana reveals that half of the fisheries catches in the Balearic islands over the last 60 years have not been declared.

There is something very fishy going on in the Balearics…

Since 1950, the number of fishermen in the Balaerics has decreased from 5000 to 700 (a massive drop/change in employment numbers), and yet the same numbers of fish are being taken from the surrounding oceans as the method of extraction of ocean life from the sea has switched to huge trawlers. However, the range of fish being taken has become utterly indiscriminate in terms of species, to the detriment of many which have now disappeared from these waters all together (inc. spider crab and angel sharks).

The report says that recreational fishing counts for a higher percentage of fish being taken from the area, accounting for 18% of fish caught. That is a huge number!

The amount of fish taken from the Balearics has been drastically under-reported by an estimated 2.5 x less than actually taken since 1950, according to Oceana’s report. This results in inaccurate estimates and quotas, threatening species and livelihoods.

It is in no one’s long-term interests to allow these trawlers free range to fish our oceans to death, and yet that is precisely what we are doing.
