Captive Bred Fish
The last decade has seen enormous advancements in the culture of marine ornamental fish. It might seem as though there is some announcement of the first-time rearing of some new species every other day now. Aside from the obvious benefits for the natural environment, this trend has been a significant boon for saltwater aquarists from beginner to expert. It should be immediately obvious why; frankly any animal raised in captivity is going to be more adapted to captive conditions.
Imagine a wild fish, just minding its own business, swimming around in the ocean, doing its thing like countless ancestors before it. Then, out of nowhere comes the net (or in some cases a mini spear gun!). This may or may not be preceded by a shot of sodium cyanide (you never really know for sure). The fish is crowded into a holding tank with many other fish and eventually transported to a holding facility. Then to another. And perhaps another. But then, some number of days later, there is the big day—the big flight. It may or may not have eaten by then. So it might already be hungry, but it certainly won’t be eating during this trip. After a day, or two, or maybe even three, of wallowing in its own wastes and choking for oxygen, it arrives somewhere. By then the pH is dangerously low… the transport water may be extremely warm, or cold…
And just when it needs relief more than ever, now comes the worst part: unboxing and acclimation. It has spent days in total darkness, only to be blinded suddenly by bright light and jerked from the box. It’s stressed, panicking even. Then shocked as it is immersed in water of very different chemistry, something it has never had to cope with before it its ever stable ocean home. Home… not what it seems as it is finally netted again (not again!) and plunked into--a tiny glass box. A miniscule, rough representation of where it grew up. Exhausted and shaken, it’s now an easy victim for the pathogens and parasites it was exposed to in the numerous holding systems along the way. And it does get sick. But will it survive?
Maybe the above narrative is a bit dramatic. But that is essentially the reality for a wild-caught fish. Contrast that with a farmed fish, raised from a larva in the same glass box. Already adapted to a life in captivity. Adapted to aquarium food. Accustomed to a human, even with a hand in the tank. It’s hard to frighten such an animal, which is more likely to start begging for food at your approach. Certainly, it is comparatively very rare for a captive bred fish to contract and spread diseases. Especially if you’ve worked in aquarium shops or hatcheries, the difference between wild and cultured fish is day and night.
In this section you will learn the differences between wild and cultured fish, with in-depth information on select captive bred species.
