Now, keep in mind that (in my opinion) one of these days the exportation of these rays will become more restrictive. They might be CITES listed this year, maybe in 10. Other countries might follow Brazil's lead. Brazil might do away with the quota and no longer allow export. They may even cease to exist in the wild. The thing that you should worry about is how are you going to maintain your ability to house these animals in 30 years if/when you can no longer get them from the wild and the captive population is crashing. More of you should be thinking about this because I think it will happen. I think there should be more focus on maintaining genetic diversity and maintaining species, seperate from the hybrid population. Your fish tank is not evolution at work.

I know there are some of you dedicated to this, and I commend you!

Thank you!!!!



I think many of you have the wrong idea about why I am against crossing different rays in captivity.

Amazongirl's paragraph sums up my feelings to the T.


I believe that we as ray keepers have a responsibility to protect these beautiful creatures that we love so much. Captive breeding is the absolute BEST way to do this.

I believe that the hobby is in no means detrimental to Potamotrygon (and other freshwater ray species). I in fact believe it will be beneficial for them in the long run.
These days they are safer in our aquariums (most of ours anyway ;p) then they would be in the Amazon. There is a mass extinction taking place on this planet once again. Whether you choose to believe it or not is on you bu it's happening everywhere.
We will be lucky if we still have any frogs in the rain forest at the end of the century thanks to that lovely Chytrid fungus.
I know I may be jumping the gun a little bit but I never want to see Freshwater Stingrays on the threatened or endangered list.

Starting captive breeding programs is the best defense!
So much effort is put into creating all of these "SP" rays.
I feel the same amount of effort, if not more should be put into breeding pure-breed rays.
When you look on these forums you barely ever see people asking for "SP" rays.
I am not saying that nobody wants them but when you hear people asking about rays it's always about Motoros, Leos, Hystrix and a few others. The more we breed in captivity the less we have to take out of the wild. This means there will be less rays killed and stressed out because of shipping.

So your saying, As long as we can keep the pure species around on their own road, seperate from the hyrbrid community it'll be ok. So that when we arnt able to take them from the wild and captive breeding is all we have left, we can atleast still have pure breed rays. That more people should put the effort that they would put into getting a few different kind of rays, into getting a breeding pair of one species, just to do thier part in keeping the pure breeds around? And creating these hybrids isnt exactly "terrible" we should just focus on keeping the pure breeds around as a first priority. ammirite? I just got into ray keeping, still trying to understand whats going on with it all :)

I'm sorry, but I have to strongly disagree with you on both these statements.

The best wasy to protect these animals is to protect their natural habitat, the Amazon and surrounding river basins in South America.

I think that unfortunatly the second statement is terribly niave. Do you have any idea how many rays die comparred to that one that makes it to the hobbyist's tank. How many of those are still alive a year later? Don't get me wrong, I'm impressed by what some people are able to do for their rays but to say that they are safer in most of your aquariums is a dream.

Believe me, I agree with you that protecting their environment is the most efficient way to protect them.
It is not that easy and I am sure you know this.
The planet as a whole is in danger and getting people to take the necessary steps to change things is going to take alot of time and effort.


In the meantime if we are going to keep these animals then we should take responsibility and do out part in preserving them.

In regards to my second statement yes you are right they are not safe in ALL hobbyist's aquaria.

Thus is why I posted the (;)) face.

There are people out there like myself who care for rays better than they would a child :)
 
After decades not 1 arowana/pleco release program has happened due to their value... all that talk about releasing pure breeds back into the wild is and will be nothing more than just talk.

Ray breeder do not practice letting the strongest survive, coupled with the inbreeding and focus on beauty... the bloodline has already been tampered with by people. I doubt the suitability of CB rays to be released back into the wild in a few decades time. It's further tampering with nature, by introducing genetically diluted rays back to compete with the wild population.

How about the less popular brown rays which not really bred much? Introducing only the popular high end beautiful rays back into the amazon is just screwing with the food chain. Nature has no preference in selecting beautiful rays, only the toughest.

...sure ...sure... save only beautiful fishes... and the Amazon ecosystem be damned.
