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.

Darwin’s Fish: Evolutionary controversies in the fossil record | University of Oxford Podcasts – Audio and Video Lectures

Great lecture by Matt Friedman on Darwin’s (and others’) discoveries about evolution and genetics, symmetry in fish, and other things.

Edit: I have since discovered Friedman, M. has written numerous papers on teleost fish, whilst writing my own essays. A very clever man.

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.
