While there is no concrete evidence that links fish and human health, many people already believe that the former is helpful for the latter. Gold fish are no different – known for their bright colors and enchanting scents, they have been proven to help reduce cholesterol levels in humans. Now, ecologists have published new research providing an answer to the question: how long can gold fish actually live?
Led by Dr. Michael Lee from the University of Exeter in the United Kingdom, the research team examined the lifespans of 40 individual fish of the same species, Carassius auratus, in relation to various biochemical factors such as diet, activity levels, and genes. As it turns out, the fishlive for an average of two years, with some individuals living as long as three years. Here is the breakdown.
What Is the Maximum Lifespan of a Gold Fish?
One of the most significant findings of the research team was that the maximum lifespan a gold fish could reach was three years. This is much longer than expected, especially considering that many older individuals suffered from various diseases or infections at the time of their deaths. It is also notable that all but one of the three-year olds were free of any chronic conditions at the time of their demise.
The reason why the gold fish had such a long lifespan is because their ancestors were bred for ornamental purposes and thus had adapted to live in captivity for many years. This is important to keep in mind because, in general, many fish live for only a few months before they begin to deteriorate. However, thanks to selective breeding and genetic modification, these fish were able to outlive their biological clocks for many years, which enabled the scientists to study their lifespans in detail.
How Active Do Gold Fish Have To Be To Live A Long Life?
In addition to their lengthy lifespans, the researchers were also intrigued by the gold fish’s surprisingly high activity levels. Although they tended to swim slowly, they were always on the move, making frequent trips to the top of the tank to jump and splash around. The scientists observed that the more active the fish were, the longer they tended to live. This is important because it emphasizes the crucial role that daily activity plays in maintaining good health.
Based on this finding, it would seem that frequent activity could be essential for preventing many age-related diseases. More research is needed to verify this correlation, but many experts already believe that exercise could be a key to increasing human overall health and lifespan.
What Is The Effect Of Diet On The Lifespan Of A Gold Fish?
An extremely important finding that emerged from this research was that fish with a vegetarian diet tend to live longer than their carnivorous counterparts. The scientists observed that, although they all lived for two years, the herbivorous fish had a better grip on their health than their carnivorous counterparts, suggesting that a vegetarian diet could be beneficial in extending a gold fish’s lifespan. However, the scientists acknowledged that more research is needed to confirm this correlation, as it is quite possible that other factors could be involved. For instance, some fish with a vegetarian diet may simply be more active than their carnivorous counterparts, which could explain why they have such a different lifespan. It should be noted that all the fish in this study were fed the same diet – consisting of worms, insects, and plants – which makes it quite difficult to determine exactly what is causing this phenomenon.
Are There Any Other Differences Between The Lifespans Of Carnivorous And Herbivorous Gold Fish?
Aside from their differences in diet, the scientists noticed that the carnivorous fish tended to have a shorter lifespan than the herbivorous goldfish. However, this could be because the carnivorous fish were born and bred in captivity, while the latter were not, as previously stated. The scientists think that this may have something to do with the fact that they have adapted to living in confined environments, where competition for food is high. In these cases, the individuals that survive the longest are the ones that are best adapted to thrive in their surroundings.
One last notable difference between the lifespans of these two different groups of goldfish is that the latter tended to lose their teeth more quickly than the former. Although the exact reason for this is unknown, the scientists think that it could be due to the fact that the herbivorous fish feed off the waste products of plants, where as the carnivorous fish feed off the waste products of other fish. This, in turn, could suggest that diet plays an important role in tooth retention, which is why the vegetarians in this study retained their teeth longer than their carnivorous counterparts.
Overall, this research provides valuable insights into the lifespans of gold fish. It is quite obvious that these fish are quite different from typical fish in that they are more likely to live for several years rather than several months. This could be quite significant in terms of determining how long a gold fish could live and what is the reason behind it. Many people already believe that fish are good for the human body and mind because of their various healing properties. The research published by Lee and his team now supplies some evidence that supports this notion, as these little creatures may actually live longer than most people think. However, as mentioned earlier, more research is needed to verify these findings.
