i have no idea whats going on in the maritimes. but i find it hard to believe that humans could ever strip the entire ocean of a certain type of fish

+1, the earth has been around a lot longer than we have, with many species going extinct long before we showed up. It's like global warming, we measure temperatures for a hundred years, notice it's going up, and say it's because of us. What about the other million's of years?

It's not that we strip the ocean of fish but rather we destroy there environment in our techniques. When a dragline crosses the ocean floor it takes any and all in its path leaving a barren landscape. Fish then loose there food sorce and ability to reproduce

Do you actually think that this resource is illimited?? Of course they could stip the entire ocean...and that's why quotas are imposed on fisheries.

And that's not going to improve since humans are growing in numbers each year...scary.

Humans are the cause of the extinction of many species, either intentionally or not.

Most extinction in the last 200000 years is because of us. Before extinction was based on new animal evolving from there prior speices. Like birds coming from tetrapods and mammals coming from sauropods. Now extinction comes from habitat destruction

Aquarium trade can drive a species out of extinction, especially if that species has limited range. Take Banggai Cardinal for example. It's "Endangered" on IUCN red list, thanks to aquarium trade.

Oh my...you would think that since they are easily bred in captivity that would not happen

That's a very sad reading but at least some village habitants are reacting to protect them. If the locals are getting sensible about this, they may have a chance.

Sorry gentlemen but your being flat out ignorant if you actually believe what you just posted.

This was an article in Science now for May of 2003, there are 1000's of articles with countless hours of study put into them all detailing vastly similar results. Do yourself a favor and go do some scholarly searches on the topic prior to posting garbage like this. Ignorance is bliss and it also happens to be highly contagious.

Quote:
Swordfish, tuna, and other predatory fish species have plunged to 10% of their abundance before industrialized fishing, according to a new global analysis. It confirms smaller studies showing that overfishing has decimated certain fish species and gives a baseline estimate of earlier population numbers that should aid in conservation.

Many studies have documented the decline of coastal marine species, from sea turtles to rockfish, but pinning down large-scale changes of fish populations in the open ocean has proved more elusive. And those oceanic studies have usually focused on individual species fished beyond recovery, such as Canada's Atlantic cod. Partly because of the difficulty of estimating population size for far-traveling fish, few studies have looked for global changes. Many have relied on estimates of unexploited abundance that are too low, because they were calculated after fishing had already begun to impact stocks.

To get at global trends, fisheries biologists Ransom Myers and Boris Worm at Dalhousie University in Nova Scotia, Canada, analyzed a range of existing data, they report in the 15 May issue of Nature. They got hold of records from Japanese oceanic fishing expeditions that use kilometer-long lines with hundreds of baited hooks. These trips have covered all open ocean except the polar seas. For fish that live in the shallower waters over the continental shelf, the researchers used data from research cruises. They found that while the vessels caught six to 12 large fish per 100 hooks whenever longliners began fishing, the catch dropped to .5 to two fish per 100 hooks in the first 10 years of fishing in a given region. On average, populations have plummeted to a tenth of their former abundance from prefishing times.

“I think what this paper gives is a magic number,” says Jeremy Jackson, a marine ecologist at the Scripps Institution of Oceanography. By giving a solid estimate of worldwide declines, Jackson says, the study makes a case for aggressive, international conservation of remaining stocks.

I think the expression "there's plenty of fish in the sea" literally holds true
Would you like to back up this statement with some proof? Nowhere near extinction eh?

Quote:
Bluefin tuna have been eaten by humans for centuries. However, in the 1970s, demand and prices for large bluefins soared worldwide, particularly in Japan, and commercial fishing operations found new ways to find and catch these sleek giants. As a result, bluefin stocks, especially of large, breeding-age fish, have plummeted, and international conservation efforts have led to curbs on commercial takes. Nevertheless, at least one group says illegal fishing in Europe has pushed the Atlantic bluefin populations there to the brink of extinction.

That link alone has over 15 full length scholarly reports detailing how ridiculous your statement was. Go read at least a few of them before you come back and post nonsense as such.

Hi,
I had to give my 2 cents. I have read that in the wild, even though clowns lay hundreds of eggs every couple of weeks for several years, they are lucky if 2 of their offspring live to become breeding adults. Not good odds. As with bangaii's, wild caught clowns are cheap for suppliers to buy making it hard for home breeders to break even, let alone make a profit.
Making the scales tip against the clownfish was the movie finding nemo which saw every person seeing this movie go out and impulse buy a nemo of their own.
It should be a great show to see the breeding side of it.
