What are some pros and cons of using the zebrafish, with whom we share many physiological attributes, to study the effect of some chemical pollutant in the ocean on the reproductive health people? a) Not only can we manipulate the level of exposure of zebrafish, they also have a much faster reproductive rate, enabling us to investigate reproductive impacts much more easily. The problem is that anything we find won't apply to people as zebrafish are only a model organisms for other fish.
b)Not only can we manipulate the level of exposure of zebrafish, they also have a much faster reproductive rate enabling us to investigate reproductive impacts much more easily. There are potential moral considerations with animal testing and results may not be applicable to humans.
c)We know that toxins affect all organisms in essentially the same way, so we can easily answer questions about exposures in humans. One big problem is that animal testing is banned.
d)Zebrafish have been shown to be the best model organisms for people, but they are very difficult to track and catch in the wild so controlling exposure and measuring impacts on reproductive health is essentially impossible.
