While i think the whole debate is interesting.. the simple answer is is.. No more or less then anyone else keeping any type of creature in captivity. Personally as someone else stated.. I'm against man made hybrids. While hybridization itself is natural. It's generally used to improve a base species genetics... not astetically please people... Blood parrots are a prime example imo of bad fishkeeping. I've seen about 1/2 these fish with physical complications resulting from their mouths. You see this alot in other animal species such as respitory problems in pugs. Just for example. a Vast majority of dogs and cats are so "captively inbred" That they have changed to resemble nothing like the original breeds. I this this happening in the fishkeeping community as well now. A vast Majority of my fish are Captively bred, The ones that are wild caught I try to offer an opportunity to breed.
It's always a fine moral line.
I think hybrids are playing god, and wrong. But I don't hold it against people who choose to keep or breed these animals if done in a responsible way. I have no use for a Blood parrot, Flower horn, or Glo-tetra. Just to name the top 3 i hear the most about.
Good fish keepers imo who breed fish strive to keep the pureness that is the fish's "wild" type. Sure bring out it's natural colors more. But breed a solid, hearty fish.
big dovii you also raise a good point as to fishkeepings strain on the environment. I'm fairly confident it is no more or less then what "strain" a dog or cat would put on the environment, and indeed less then ourselves. workign in a LFS you see the "industrial" side of things and useage. as for the salt in SW tanks doing damage, salt can destroy plants.. to what extent, and at what levels. I'm not an expert by any means. But I can pretty much gaurantee you it's alot less hazardous then the super farm a few miles down the road from me w/ however many hundreds of head they milk now. The chemicals pumped into the food they feed those cows then what goes into the milk you drink. The environmental strain is already being seen here and it's been less 'n 10 yrs. since the megafarm was built. may sound like I'm compareing apples to oranges. But my point is fishkeeping "looks" worse then actuality i believe at least on that level. That is not to say we fishkeepers should not be always trying to find more environmentally friendly ways of keeping our fish.
Never seen this show the cove before. But I know dolphins have bred in captivity, as well as a large handful of other aquatic mammals. If this trainer truely felt the way they did they should be working to "free willy" and not belittle their chosen profession infront of millions of people. If what they think they are doing with their knowledge of the dolphin and captive husbandry is wrong. Then to still do it w/ the beliefs it's torture/abuse/ect ... Is worse 'n someone out of ignorance tossing an Oscar in a 10 gallon tank.
And Turning the channel teaches you nothing. Walking away from things is the F'd Up American way. And it's wrong.
But thats all just my oppinion
