Fish Mirror

He added it did not necessarily imply fish were self-aware, but the findings challenged the idea that animal intelligence follows a continuum, with chimpanzees at the top and fish, insects and reptiles at the bottom. When carp were first brought to England, in 1496, it had already become a widely available food source, which was now not exclusively served to the nobility. As the standard of living in Europe and Greta Britain rose, so did the demand for carp.

Mirror carp, regionally known as Israeli carp, [note 1] are a type of domesticated fish commonly found in Europe but widely introduced or cultivated elsewhere. They are a variety of the common carp ( Cyprinus carpio) developed through selective breeding. The name "mirror carp" originates from their scales' resemblance to mirrors. They can grow in excess of 60lb (27kg) – the last few British record fish have all been mirror carp. Their findings suggest that a small, otherwise unremarkable species called the cleaner wrasse has joined an elite handful of others to have passed the so-called mirror test, which has been used for decades as a gold standard measure of animal intelligence. The mirror’s scales are probably its most obvious feature. This fish is very scarcely scaled and sometimes only has a few patches of scales of varying size scattered over its body.As the carp is a bottom feeder, the best way to fish for mirror carp is by ledgering, which means fishing your bait on the bottom using a weight.

Mirror carp have a rather long dorsal fin, a wide and big tail fin, as well as large and roundish anal fin, pectoral fins, and pelvic fins. Passing the test is widely viewed as an indication of self-awareness and until now the only animals to have crossed this threshold are great apes, bottlenose dolphins, killer whales, Eurasian magpies and a single Asian elephant. Now the select club may have an unlikely new member. The research concludes that roughly 36% of the original mirror carp population, in both wild waters and fish farms, were fully covered with scales.Mirror Carp are not usually kept their whole lives in an aquarium due to their large size. If you keep juvenile Mirror Carp in your home aquarium until they are too large, you will be happy to find that they are a peaceful and slow-moving species. You will still want to ensure that you keep them with other fish that match their temperament. It is not a good idea to keep them with fish that are territorial or food aggressive. Goldfish and Koi are a good choice for a Mirror Carp tank or pond mate as they are similar in temperament and require roughly the same water parameters to thrive. Do Mirror Carp Exist in the U.S.? Prof Gordon Gallup, a psychologist at the University at Albany in New York, who pioneered the mirror test in 1970, disputed whether the fish really recognised themselves.
