The Effect Of Temperature Affect The Metabolic Rate Of Carassius Auramus On Goldfish

This lab was about how a goldfish’s breathing rate changes in different temperatures in order to maintain homeostasis.

Ectothermic animals are animals whose body temperature is affected by their surroundings. This means that if the environment is cold the animal will be cold. If the environment is warm the animal will be warm. This is because the animal doesn’t have the capability of regulating its body systems to keep a constant body temperature. When an ectothermic animal is cold, its heart rate will lower. When the animal is warmer, the heart rate will raise – as long as the temperature isn’t sufficiently high to harm the animal. (Campbell, 2005)

At the conclusion of the experiment, the two hypotheses were reviewed. Because the water temperature did affect the normal respiration patterns of the goldfish, the null hypothesis was disregarded and the alternative hypothesis was accepted. From the results of this experiment, it was concluded that although other environmental factors could play

2. You have measured the rate at which a fish breaths at various temperatures by counting the rate at which its gills open. The data table is shown below. Create a line graph depicting the results.

Freeman (2008) furthers Eckert et al’s argument by stating that the actin filaments of the muscle cell in organisms are able to intake ATP (adenosine triphosphate) faster and will move the organism faster when higher temperatures are imposed. This is because of an increase in enzyme reaction rates (Freeman 2008). These arguments can be applied to our experiment to help explain the trends observed. It can be argued that as the Gammarus setosus experiences the cold treatments, the organ of Bellonci senses the cold temperature, which in turn signals the organism to preserve its energy to protect itself; therefore, the organism will swim slower. In addition, the enzymes in the muscle cells of the organism, when experiencing the cold treatments, will have decreased ability to carry out enzymatic reactions, therefore inhibiting the uptake of ATP, which will cause the organism to swim slowly. Conversely, as the organisms are put into the heated treatments, the organ of Bellonci senses the heat, and allows the organism to swim faster, since it does not have allocate as much of its energy towards survival. Furthermore, the enzymes in the cells will be able to catalyze reactions more quickly, therefore allowing the organism to swim faster. However, when the temperature of the surroundings is too high, the enzymes will denature, therefore, reducing the activity rate of

direct calorimetry. Furthermore, the amount of oxygen in the chamber reveals the amount of cellular respiration of the organism. While also, test the effects of decreasing oxygen, and later increasing the heat on the metabolic rate of goldfish. I hypothesize that an increase in temperature will increase their metabolic rate

The Artemia franciscana can survive in extreme conditions of salinity, water depth, and temperature (Biology 108 laboratory manual, 2010), but do A. franciscana prefer these conditions or do they simply cope with their surroundings? This experiment explored the extent of the A. franciscanas preference towards three major stimuli: light, temperature, and acidity. A. franciscana are able to endure extreme temperature ranges from 6 ̊ C to 40 ̊ C, however since their optimal temperature for breeding is about room temperature it can be inferred that the A. franciscana will prefer this over other temperatures (Al Dhaheri and Drew, 2003). This is much the same in regards to acidity as Artemia franciscana, in general thrive in

The water in the hot bag was approximately 65° Celsius. We allowed the shrimp to move about for 30 minutes because we had the time. Every 10 minutes we replaced the hot water in the bag with fresh hot water because it was slowly cooling down. After the 30 minutes were up we closed the clamps and removed the hot and cold bags from the tubing and counted the number of shrimp in each section and recorded our results. We did not count any dead shrimp because that condition would obviously not be a condition they could survive in. In this part of the lab we measured the temperature of water from each section and recorded that number also. We did this by simply pouring the water from each section into 4 different test tubes and placing a thermometer in each.

Questions to answer in your lab report. NOTE: some questions pertain to the week 1 exercise, some to week 2, and others to both. How is the amount of temperature variation related to the volume of the water body? How might you measure the speed of temperature change? How would you expect the speed of change to vary with habitat volume? Are water temperatures different than air temperatures? How are they different? Are there any cyclical patterns in the temperature-logged data (“time series”) from Angel? If so, what do you think caused these repeating patterns? Based on the results of this exercise, how might you

Ectotherms like Gryllus (Niehaus 2012), commonly known as crickets, instead depend on external sources for their body heat. Ectotherms must use the environmental energy and behavioral adaptations to shift their body temperature. The basal metabolic rate (BMR) is a measure of the rate at which an organism releases heat after breaking down food molecules. Crickets possess the ability to respond to thermal change by

The null hypothesis for this experiment is that there is no statistically significant relationship between the metabolic rate of goldfish and their exposure to light. The alternative hypothesis is that goldfish exposed to ambient light will exhibit a higher metabolic rate compared to goldfish that are exposed to dark light. Results Overall 86 goldfish (N=43) were used in the experiment. Altogether, 43 trails (2 fish per trial) were conducted in order to track the metabolic rates of the fishes. Differences in metabolic rates (with respect to light exposure) were calculated by measuring the changes of oxygen concentration in the water chambers where the fishes were placed.

Breathing rate of the goldfish decreased with the decrease in temperature. The null hypothesis, the temperature will not affect the breathing rate of goldfish, was rejected and alternative hypothesis was accepted. It was concluded from this experiment that the organisms belonging to the class Pisces become inactive during significant drop in temperature. It was concluded that fishing was mostly done during the summer because the high breathing rate results in high metabolism and hence fish needs more food. Despite some errors, our experiment was concise. More accurate data could had been drawn with the presence of large number of groups performing the same experiment. The fish we experimented were not tested whether they were diseased and also,

he safety precautions taken to avoid injury to the goldfish or students was Animal Safety, Sharp Object Safety, and Biological Safety. Multiple goldfish were dealt with therefore the students needed to handle them with care. The water the goldfish were in was very dirty and in glass. Therefore, it was necessary to be cautious of the glass which could hurt a person if dropped. Does the temperature of the water affect the breathing rate of the goldfish? The temperature of the water does affect the breathing rate of the goldfish. If the breathing rate of the goldfish is affected by the temperature of the water, then the goldfish’s breathing rate will speed up when the water is colder and slow down when it is warmer.

We prepped for the experiment by turning on the hotplate and giving it time to heat up, putting water into a large beaker, plugging the temperature Probe into the computer, placing the rubber stopper into the Erlenmeyer flask, and connecting the pressure tube into the rubber stopper. Next, we used a ring stand to lower the Erlenmeyer flask into the water

The important contribution of fish intestinal carbonate precipitate production to the ocean carbon cycle has recently been highlighted (Wilson et al., 2009) and raises a new dimension to ecophysiological studies of the interaction between fish and their environment.
