Betta Fish Lab Report

The purpose of this lab was to answer the question, “Of the saline solutions of 0%, 0.5%, 1%, 1.5%, and 2% sodium chloride (NaCl), which solution will yield the highest hatching viability for the brine shrimp?” The hypothesis was that the saline solution most precise to the concentration of NaCl in seawater, which is approximately 3.5%, will yield the highest hatching viability. Therefore, the 2% NaCl solution will yield the highest hatching viability.

In this experiment the independent variable is the length of worm between 15 centimeters, 20 centimeters, and 25 centimeters. The dependent variable is the length of bass in centimeters. The 20 centimeter worm will catch the longest bass. In this experiment, the same fishing pole needs to be used and the time of day needs to be the same for each trial. Also, all the fish caught and measured need

This experiment will help look for indirect effects caused by interaction modification between a Guppy (Poecilia reticulate) and Daphnia by altering their physical environments by controlling the absence/presence of plastic aquatic

- To test this hypothesis my experimental approach would be testing different bodies of water or testing one and just testing different areas while tracking the fish.

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

In the laboratory exercise, two species of Gambusia (Gambusia speciosa and Gambusia krumholzi) were used in order to compare the fecundities of both species. It is proposed that, just like other vertebrates, there is a relationship between the sizes of a female their pregnancy status. Smaller fish would most likely be prepubescent and not able to reproduce. Larger females could have most likely gone through menopause and also not able to reproduce. Therefore, it is highly likely there are higher averages of pregnant fish at average sizes.

When I was about six years old, my older brother and a few of his friends thought it would be funny if they removed the divider between to the two betta fish we had in the tank. Bettas are very aggressive and territorial fish and like to be left alone, so the second that they removed the border, they started attacking each other. Even though they are just fish and are very small, but it was blatantly obvious that they were doing harm to each other. He later put the borders back up but a few hours later, one of them had died. I blamed it on the fact that my brother had done that to the fish and told my dad. My brother, of course, got in trouble but my dad told me that the reason why one of them died because he was too weak and could no longer

Two of the glow sticks will be blue whereas the remaining two will be red. However, in order to test the effect of bright colors against dull colors, I will be wrapping one blue and one red glow stick in wax paper in order to make their colors dull, leaving the other two unwrapped to give off a brighter color. I will also use two male B. splendens, both of which will be contained in their own, two gallon, plastic aquarium filled with water. To monitor the temperature of the water inside the aquariums, a thermometer will be placed in each. One of the fish, inside its aquarium, will be the experimental group while the other fish will be the control group. The experimental group will be exposed to only one glow stick at a time, whereas the glow sticks will be absent from inside the control group’s aquarium at all times during the experiment. Cardboard will also be required, as it will act as a barrier between the two aquariums. This barrier will prevent any light from the experimental group being visible to the control group. In addition, the cardboard will keep both fish visually isolated from each other, which will, in turn, prevent the two fish from being aggressive towards each other and affecting the data. Finally, I will use a timer to keep track of the amount of time that the experimental fish was exposed to each glow

The Crown Tail Betta has a remarkable tail, which is different from other Betta. It is a type of “Siamese” Fighting Fish. These fish have been bred over the years to improve the fins and colors of the male species. It can also make these fish more aggressive. The Crown Tail Betta has a teardrop shape to its tail, whereas the Twin Tail is split, giving the impression that it has two tails.

In exercise 1, around the Rocky Coastline there was a population of Darwinian Snails. These Darwinian Snails had a variety of shell thicknesses. The shell thicknesses were put into a histogram. There were around fifty Darwinian Snails at the start of this experiment. Three to five European green crabs were released to feed on the Darwinian Snails. When the Darwinian Snail population was around twenty-five, the European green crabs were taken away. The Darwinian Snails were given a chance to reproduce. Once the population reached about fifty, the European green crabs were released to feed again. All together the European green crabs had twenty-five Darwinian Snails for three meals.

In order to give the viewers more information about Tilikum, Blackfish incorporates interviews of men who worked in the whale capturing  business. By doing this, the viewers could not help but feel sympathy for the animals. One man went into description on how they went upon their business. He states that they were only after the young ones so during the extraction, he remembers hearing the babies cry out for their mothers. By the end, they had three dead whales in their net. Three men then cut open the whales and filled them with rocks so they could sink to the bottom of the ocean. In 1976, the state of Washington gave out a court order telling Sea World that they were not allowed to hunt for whales there any longer but that did not stop this

The male betta crown, also known as Siamese fighting fish, is a popular choice for owners of fish. They have a wide variety of colors and shapes, and are very robust when it comes to adapting to an aquarium. The crown betta has that name by the unique design of the fin with which it has been raised. These fish create a dramatic impression with its vibrant colors and extreme extensions of the

Özogul and Özogul (2006) found that putresine concentration increased during the storage period of sardine held in air, VP and MAP, reaching maximum levels of 12.2 mg/100 g at 12 days, 7.59 mg/100 g at 10 days and 5.83 mg/100 g at 10 days, respectively, whereas cadaverine levels reached of maximum level of 10.0 mg/100 g for fish stored in air for 15 days, 5.73 mg/100 g in VP for 10 days and 5.21 mg/100 g in MAP for 10 days of

Because we are looking at the behavior of fish in response to tapping, we cannot use an alternative to live animals. We chose to use feeder guppies because they are a small, schooling fish that has a known set of behaviors that can be easily observed. In all, we will be using ninety guppies for the duration of this experiment. We need a large number of guppies because we will have nine tanks for repetitions

(Wachirasiri et al., 2016) examined the effects of amino acid type, concentration and pH on yield, texture, and colour of both cooked and uncooked shrimp after a freeze-thaw cycle and Sensory evaluations of the treated cooked shrimps. This study reported amino acids were also improved yield of white shrimp (table 2). Compared to the control, shrimp treated with glycine, arginine, lysine and proline improved product yield. Treatment with NaCl could improve WHC by thawing yield and cooking yield of the fresh shrimp sample. Chloride ions were more strongly bound to the protein than the sodium ion, resulting to an increase of net negative charge of protein. The electrostatic repulsion and increased interfilamental spaces allowed more water molecules to be penetrated and adsorbed into.
