Wow, that would make sense, i mean the are the most sought after upper jaws, is retropinnis and polli not VU?

Polli population actually increases each year so they are safe. Not sure about the status of retro. Lost many of the PDF documents I gathered from the internet when I moved out of my parents place. You might as well search in the internet maybe they are still around in PDF format. Many are for sale though and xan be access only with payment. It sucks.

Not my pics. Credit to the supplier.

This is how bichirs are being held after they are collected in the wild. They are not being feed until an exporter/imported from foreign country orders from them. Who knows how many days/weeks they stay in that container. Some will end up for human consumption but many are being ship abroad.




Compare to what being sold for human consumption

This poor bichirs! There is barely any water in those bins... I just wanna go down there and rob those ppl of all their bichirs and put em all in my tank 😁..... But for real that's not cool makes me wanna by more to give them a better fate/life

The more u buy WC bichirs the more WC bichirs are gonna end up like this.

What did you type in to search for these docs? When I have some spare time I might try and hunt some of these docs down.

Try searching african fauna population or african fauna population depletion.
 
Good thread. I have wondered about this myself. No doubt you have all read at least a little into the devastation our saltwater counterparts have had on reefs. There are efforts being made to right our wrongs, but some areas have been hit really hard. There is an episode on human planet (oceans) that shows precisely how extreme the methods being used to overfish can be/are. Practically every fish in an entire reef is taken by a large group of fishers in the documentary. Those fishers have wiped out nearly all ocean life in their area.

Look into bottom trawling. Really, google it. If you aren't familiar, you will be shocked by how capable we have become at mass-fishing. Its horrifying. You really have to see it to grasp what's going on. Words aren't really enough.

It is worth noting that our hobby is much less destructive on populations than overfishing for consumption, and reef collection for sale to private collectors. What really threatens freshwater fish is habitat destruction.

The world is a series of watersheds. If you aren't familiar with the term, it is simply explained. Hold your hand out, palm up. Level it. Now bring your fingers upwards. Drop water on the tips of your fingers. The water all comes rolling down your hand. This is a simulation of what happens when it rains. The creases in your hand are rivers, the puddles lakes. Your palm is the ocean. Water travels greater distances than you might think. All along the way it collects all sorts of things such as minerals.

When we urbanize areas, we disrupt the flow of water. Concrete does not absorb water as easily as the ground in an untouched forest. This causes flooding of areas that have never been flooded before. The flooding erodes stream banks, and carries all sorts of nasty, water quality altering chemicals like fertilizers into the streams and surrounding watersheds.

The effect is devastating. The nationwide watershed that cuts through the center of the united states and empties into the gulf of mexico has created a massive, unlivable section of the gulf called "the hypoxic zone."

When I say unlivable, I mean unlivable. There is not enough oxygen in the water to support life.

Great image of the devastation. The gulf hypoxic zone is the second largest in the world. Keep in mind that the devastation is not limited to the gulf. Every body of fresh water in the watershed is being affected on some level. If you know of a stream in a mildly urbanized area, go and check it out. I can send you forms to aid in the testing of biodiversity and density, as well as numbers that your local streams could be compared to.

At my I university, we tested the bio-diversity of a handful of local streams in both rural and semi-urban areas. Large portions of each stream were tested. The results were shocking.

Anyway, that's my rant. Habitat destruction can be almost effortless on our part, but it generally isn't.
 
I definitely think that it probably has some effect of the population of the species in their natural habitat. I think thats why today we are becoming more aware that breeding them and purchasing them from the suppliers are better than importing and exporting them straight from the wild. Plus there are a lot more benefiits being tank raised.
