Aquarium Reserch Paper

Brine Shrimp are a micro-crustacean that is found mostly in inland saltwater bodies, however, the salinity levels that they live in vary greatly. The conditions that they require can be made at home as the eggs (cysts) of the shrimp are dry, hard shells that can withstand drought and go without water for up to 50 years. This study presents the results of 3 different salinity levelled environments to the Brine shrimp in order to discover a salinity level that produces the most successful hatching rate. By filling 3 Petri dishes with 20mL’s of purified water, each dish contained varying sodium chloride amounts from 15ppt, 25ppt, and

Another thing that we did that was really cool was sample some Spotted Sea Trout that were about 2 weeks old. We got samples of fish to look at how much they they were eating. We also took their length and weight to see how much they had grown over 2 weeks and to make sure they were growing at the right pace. We took a net and walked through one corner of the pond and got about 20 samples and put the fish in a cup and took them into the lab. When we got into the lab, I had the sheet and recorded down the weight and length when he told me each one. We then compared it to the average weight, length and weight of 2 week old Sea Trout. Surprisingly they were over average which was not expected because it had been overcast and rainy the past week and that usually makes the fish not want to eat as much. We thought they would be under average. One thing that was really remarkable about looking at the fish was that you could actually tell if they were eating or

The procedure for this experiment followed the steps as shown in the flow chart (Figure 1) and will be expanded upon here. The oxygen-measuring probe in the test chamber was first turned on and required 10 minutes to warm up. During this time, two empty containers had 200mL of fish water added to them and then each was weighed using a scale that was tared to zero before use. Two pairs of goldfish were then collected from the large tank #1 in the lab room using the fish net provided, and one pair was placed in each container. Then, the containers were reweighed separately and the original weights were subtracted from the new weights in order to determine each pair of goldfish’s weight. Two trials were conducted and in each trial, each goldfish pair was subjected to two conditions, first a control condition where no factors were introduced, followed by an experimental condition where they were exposed

Answer = It would have categories for the number of fish, the amount of water, the tempature of the water, and if nutrients were added.

An entire new world, different from our own exists beneath the surface of our oceans. This life is full of color, shapes, sizes, wonder, and even darkness. Much of this life has yet to be explored but we still know that beneath the waves exist the most beautiful creatures and the most bizarre. Magical areas such as the coral reef and mysterious areas such as the depths of the ocean are homes to over 700,000 species that live in the ocean. This includes the eighty percent of the ocean that has yet to be explored. Even though there may be separate oceans on this planet, they are still interconnected by a body of salt water. No area of the ocean is the same, which brings us to the wonderful fact that so many different species are able to flourish

The first time I felt the recoil of a shotgun coincide with the simultaneous drop and flop of a turkey I knew I was hooked. This was all the way back in the fall of 2005 when I shot my very first turkey alongside my father. That day started an addiction that has since intensified and spread to not only turkeys but almost all of Missouri's highly sought after species. Hunting, conservation, and the great outdoors have always been embedded in the hearts of my family. I am no different and plan to dedicate my life to Missouri’s wildlife the same way they have.

For the initial set-up of the experiment, two plastic beakers, each containing approximately 200mL of fish water, were individually weighed and recorded. The selected model organism for the experiment was the Carassius auratus, most commonly known as the goldfish. Each beaker was then filled with two pairs of evenly-sized goldfish and reweighed. These weights were then subtracted by the previously recorded weights to provide an approximation of the combined weights of each paired goldfishes. An oxygen chamber with a built-in probe was then filled with 200mL of fish water. The first pair of goldfish was added, along with the 200mL of fish

In order to determine if the entire class was able to reach the objective, Ms. Meaghan and I took anecdotal notes during our observation groups about student’s observations and quotes about each basic need. In each group, each student was assigned a job, which was described on each card. Their jobs related to providing the goldfish with their basic needs for survival. Three students in each group were feeders, four students were planters, and four were water changers (two added water and two replaced). The feeders each received a piece of scrap paper with some food on it, and each student took turns feeding the fish. The planters each put a sprig of elodea in the tank to create shelter. The two water removers, each took a small Dixie cup of “dirty” water out of the tank, and the two water adders, put one small Dixie cup of conditioned water into the tank. Through their work in their small group, the students were able to develop an understanding of each need of goldfish, and understand how to provide it. They were able to have a chance to actually provide the

--Today, while dissecting a dogfish shark, I was bombarded by memories of the dissections I performed during my junior year of high school. Mrs. Strieby’s Zoology classroom had been filled with the same cold, metal dissection pans and the same repulsive stench of formaldehyde-soaked fish. Because I had forgotten how the interior of the organism looked, I was filled with the same excitement and fascination when I saw its unusual internal organs. Various points throughout my life have a certain vibrancy in memory. I have noticed that these special periods coincide with learning new, captivating material; participating in events that disrupt my normal routine, or when I progress in my relationship with Jesus Christ. Second semester of junior year

Brine shrimp are used as live food for aquatic life in aquariums. Brine shrimp are usually easy to hatch out, but water types may make a difference in their viability. This study is being conducted in order to see if there is any significant difference in the types of water used in hatching out brine shrimp eggs. In which type of water do brine shrimp eggs hatch best? By studying the different types of water that could be used and knowing which one provides a better hatch rate, a benefit will be seen by using the best type of water to hatch out future brine shrimp. I believe this project will set out to prove that brine shrimp eggs will hatch best in ocean water.

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

Before attempting this lab, we conducted some research on what conditions catfish need to survive in an area. Catfish are better off at temperatures ranging from 88-90 degrees Fahrenheit. Their preferred dissolved oxygen levels are at least 4 ppm.(http://www.thefishsite.com/articles/1907/water-quality-monitoring-and-management-for-catfish-ponds/). The diet of catfish often changes as they age. Younger catfish primarily feed on aquatic insects such as dragonfly larvae, water beetles and fly larvae. By the time they're adults, catfish consume small fish, seeds, aquatic plants, algae, crawfish and snails.(http://animals.mom.me/catfish-eating-habits-9466.html). The alkalinity of the water needs to be at least 40 ppm but the catfish will be happier

Brook trout are a very needy species of fish. If this fish is being kept in a tank, it will need many specific things. For example, when they are still unhatched eggs the trout need their surrounding water to be dark. To do this you could simply put up a curtain to keep the light out of the aquarium. Additionally, the fish will need chilled water. This can be achieved by using a water chiller to keep the water in the tank around 50 degrees Fahrenheit to 55 degrees Fahrenheit. If the chiller fails, then a solution is to put frozen bottles of water into the water, then (once they melt) switch it with another bottle and refreeze the one you began with. In addition to all of those needs, trout also will need to be fed every day. The best thing

For this experiment the independent variable is the crayfish and elodea while the dependent variable is the respiration rate measured in NaOH. The elodea and crayfish were placed into two different graduated cylinder containing 30ml and the volume displacement were than recorded. Once finished measuring, three beakers were obtained, labeled and 100ml of tap water was added to each beaker. The control group is beaker 3. The beaker containing elodea was completely covered in foil and placed into a dark cabinet to avoid photosynthesis from happening for 15 minutes. After 15 minutes, the crayfish and elodea were taken out and placed back into their tanks. Four drops of the pH indicator phenolphthalein were added to each beaker. NaOH was dropped

There is something fascinating and relaxing in having an aquarium in a home. Like a fireplace’s warm glow and bright colors, the colors that are emitted from an aquarium can be just as warm and even more colorful. From the slow and graceful movement of the fish to the frantic feeding frenzy, an aquarium is different each time it is viewed.
