Goldfish

Although, according to the IUCN Red List of Threatened Species, this carp is of least concern, it’s population trend is decreasing (Freyhof & Kottolat, 2008). This native species of carp was once widely distributed across the British Isles but is now experiencing extirpation due to competition in habitats where it does not thrive. The most significant threats are caused by introduced species; such as the closely related and often confused with Prussian carp Carassius gibelio, a subspecies of the congeneric goldfish Carassius auratus which could lead to local extinction in many of their native areas (Smartt, 2007). In addition to this, the physical similarities between the Crucian carp and goldfish C. auratus has inadvertently stunted conservation efforts. This is because it is likely that goldfish had been mistaken for crucian carp when restocking ponds in an attempt to raise population in the 1980s (Wheeler, 1998), meaning that it is expected that goldfish were introduced to the majority of small ponds around southern…

fish can only thrive and live in much cooler temperatures, nothing exceeding 60 degrees, or else they start to die. Minnow fish are commonly used as bait fish and react extremely to temperature differences. Many die within a few minutes when temperatures are too extreme for them. Minnow fish cannot live with temperatures over 60 degrees fahrenheit and thrive with temperatures 55 degrees or lower. So how do they remain in a state of homeostasis with different temperatures. Fish are very social…

The carp could act as however it is being portrayed as or it could mean something important to what it is being associated with. Many mythical symbols have a beginning, such as the carp. There are stories about the origin of the carp, but those are not one-hundred percent true. “The real origin of those coloured creatures was in truth, more of an accident than by any real intentions and they are truly ‘man made’” (“Origins and Myths” 1). The carp was discovered unexpectedly instead of having a…

Color Variation in Venezuelan Guppies Guppies are one of the most diverse fish in the world. Some guppies are brightly colored and some guppies are drab and dull in color. The color variation within Venezuelan guppies interested scientists to find out how color variation within the guppies occur. So what causes the color variation within the Venezuelan guppies? The three factors that causes color variation within the guppies are the predatory fish residing in the pools, the amount of…

For example, the poikilotherm species, Carassius Auratus, also referred to as the goldfish, has a metabolism that can easily be manipulated. One of the most practiced ways of manipulating the metabolism of a goldfish is to increase or decrease the temperature of its environment. Other techniques used to manipulate their metabolism include altering light intensity and introducing stimulant drugs into the environment (such as caffeine or nicotine). Studies have found that, as a stress response,…

Temperature was effective in goldfish number of breaths per minute. As water temperature decreased from 22℃ to 10℃, the average number of breaths also decreased. The mean of the average number of breaths is 69.24. The number of breaths in the study ranged from 16 to 135 breaths per minute. The null hypothesis, that the temperature of the water has no effect on the number of breaths per minute, can be rejected. The results support the alternative hypothesis. The control fish number of breaths per…

Imagine living life as a goldfish. From the very moment it’s life begins, the tiny, innocent specimen is engulfed in water. Given the ability to communicate with the goldfish, one might mention the presence of water. The response would be something along the lines of: “Water? What is that?”. Even though the goldfish relies on water for survival, it would not be aware of it’s surroundings. When confronted with this observation, the goldfish might become defensive or taken aback. “Water isn’t…

Average Metabolic Rate Difference of Goldfish in Dark vs. Ambient Light Introduction Metabolism is an interesting field of study to better understand what is happening inside of the body of different organisms that keep them alive. Goldfish (Carassius auratus) were used for this experiment since these small animals metabolism can be easily influenced by different variables. This is due to the fact that goldfish are poikilothermic whose internal temperature is influenced by their surroundings.…
