I think that this happens in my house on a daily basis. Diapers and a bib anyone?
Anyone else feel like the electronics are taking over? I'm forced to sit and stare at an inanimate computer screen on a daily, 7 hour basis, while my mouse plays games on me, deciding at the most inopportune moment, that it's going to shut itself off, laughing in my face as I struggle to minimize the Internet porn sight that I have open on my desktop while sales people are pouring into my office. Actually, I don't look at Internet porn - especially not at work. I'm not that stupid. I only look at dog sites. And no one really pours into my office - I try to make it as inhospitable as possible. But the mouse teases and taunts me, flickering it's little red light in my face ... isn't that a laser beam or something, that could destroy your vision with even an inadvertent glace in it's direction? My mouse at home is much more forgiving with me, never gives me any issues, doesn't turn off at odd times, doesn't try to burn my eyes out and never talks back. Oh, but to go back to pencils, pens, erasers and paper. Computers and other electronics can be bad for your health, or so they say. As far as I know, pencils do not cause cancer, and they're not bright enough to take over.
It’s easy to kill a fishThe below are links to articles about the recent Calgary Zoo Cow-Nose Sting Ray inquiry:
It’s easy to kill a fish. I don’t mean intentionally, but inadvertently. It is such an unnatural environment when they are held in captivity, living their life behind four glass walls, with so much that can falter in such a close-knit, small ecosystem.
Minute changes in water temperature, ph, hardness, deficiency of dissolved oxygen (allegedly in the sting rays case) and levels of elements can reek havoc among a community of aquarium fish. Not to mention keeping aggressive species together. Captive bred animals are hardier in their tank raised environments, adapting to changes with more ease than their wild caught brethren, though the chance for mishaps still remains high, especially with more sensitive species.
So, can I fault the Calgary Zoo for their recent loss of those beautiful cow-nosed sting rays (which I had the pleasure of viewing and interacting with at the Toronto Zoo – amazing creatures, full of intelligence and personality)? I’m not sure that I can find them fully at fault, as there are issues with keep fish in a captive environment that are sometimes beyond control (though I will not speak of the other losses that have also recently happened with some of their mammals).
So many factors must be taken into account when dealing with aquarium species. My husband has been involved with raising and breeding fish for more years than I can count. And he has seen his ups and downs with these water dwelling creatures.
Tanganyikan cichlids, namely the tropheus variety, can really shoot down your confidence when raising and breeding these African beauties. They need hard water, they need specific ph levels, nitrate/nitrite levels, acidity levels, and temperatures or they do not thrive. The levels fluctuate, and they become sick. A loss of a whole colony can happen overnight as they are extremely sensitive to the aquarium environment. No poisoning, or toxins involved, which was the original hypothesis on what happened to the rays. And this can happen with many other species of captive, aquarium raised fish.
We had an incidence with our Koi Angels, in a tank that housed many different types from tetras to discus and rainbows. Overnight, the Kois all died, including one in a separate tank. We have no idea why, as the other fish living with them were completely unscathed an thriving.
So, unknowingly, it is very easy to kill a fish. It does depend on the sensitivity of the species that you decide to raise. Each type is different, and some handle changes in environment much better than others. My hump-backed limas are a perfect example of a hardier species, as they thrive and breed in water that doesn’t get changed on a regular basis, and that fluctuates in levels frequently (most likely the nitrates/nitrites are higher than they should be). They are just a hardier fish. Sting rays, apparently, are not.
This is the same, regardless if the fish are salt water or fresh water. Some are more sensitive to what we think might be insignificant changes than others, and environments need to be closely monitored in order for the fish to thrive.
It truly is a huge loss to have so many of these sting rays loose their lives – if you’ve been able to interact with them, you will know they are unlike any fish you’ve been in contact with before.
So is the Calgary Zoo at fault? I suppose in the long run, even though unforeseen circumstances and changes can happen in an instant when keeping fish in a tank or other captive environment, they are to blame as they are the keepers of these elegant creatures, and the rays depend upon the zoo staff for survival.
I would like review the long term effects that the handling of these rays has on their health. Precautions are taken before the viewing public is allowed to enter the tank area, however, this is definitely not a fail-safe, and I can not see human handling being good for their health in any way.
I just hope in the future more diligent measures are taken to ensure that no more harm comes to these delightful, intelligent and personality filled sea dwellers. And I hope that the Calgary Zoo is able to overcome their recent tragic losses, and move forward for not just the benefit of the zoo, but for the benefit of the animals that they protect.
I've never seen a robin in the winter, let alone heard one sing in the fridged weather, until this year. I, along with I'm sure many others, always assumed that the robins flew south for the winter, and only reappeared to announce that spring would be arriving shortly around the March/April time period. In the last few weeks I have observed more and more of these little red-breasted fellows roosting in the trees outside our office building. They even go so far as to sing a little in the cold morning air as I arrive for the 9:00am work day. This starts my day off great, however doesn't carry the mood into the building, which is unfortunate.
