The Compiratory Process Of Freshwater Fish And Saltwater Fish

Some plants and animals have to adapt to the amount of oxygen and visibility underwater. For example, plants have adapted to the amount of sunlight they receive in certain environments, and cattails and water lilies have adapted to be able to survive humid climates. For animals, certain fish like trout have adapted to clear and cool water with a large amount of oxygen. On the other hand, other types of fish, like catfish, are able to survive in an area with a low oxygen level and gloomy visibility. Since otters live on the land surrounding the water, they have adapted to be able to swim to catch their food. Frogs and alligators have adapted to their environment by being able to live on the land after coming from underwater as an egg. Lastly, beavers have adapted to use their teeth to create the dams they live

The increase of oxygen does not necessarily mean the fish will keep up with it. Too much oxygen can be harmful to the fish so you would need a certain amount per area of fish. A constant flow of oxygen going throughout the water habitat.

For the Most part trout are fresh water fish, but even some of the ocean species return to fresh water to reproduce. As they are from the Salmon family you can see what is meant by that. Even our commonly associated fresh water trout such as Brown, Brook, Bull, Cut Throat and Char have taken to the oceans and thrive very well there.

They have gills covered by an operculum that increases respiratory efficiency by creating negative pressure that both draws and pushes water across the gills. They have a gas-filled pouch for gas exchange in low-oxygen environments that contributes to buoyancy. A few species use diffusion across their skin.

Angle Fish can live in a habittat that is either fresh water or salt water. An Angle Fish thats home is in salt water is called a marine Angle Fish, and other Angle Fish that live in fresh water are simply called Freshwater Angle Fish.And despite there small aperance, Angle Fish are very friendly to divers and will even

Salmon are semelparous animals, meaning they only spawn once in a lifetime. The fish then quickly deteriorate and die. Not being able to adapt to the freshwater after being in the saltwater ocean for so long.

The purpose of this lab report is to determine the effects of a different environment condition such as temperature on the consumption of oxygen and ventilation in goldfishes (Carassius auratus). The consumption of oxygen and ventilation rate was measured in goldfishes at different treatment levels inside the tanks; ~ 25°C and ~15°C in a 15 minute time interval for one hour. At ~ 25°C, the ventilation rates in the goldfishes were higher than at ~ 15°C and there was more oxygen consumption at ~ 15°C than at ~ 25°C. The results suggest that the ventilation rate is greater in high temperature than low temperature. Also, there is more oxygen consumption at lower temperature than at higher temperatures. This experiment shows that temperature is

The rainbow trout (Oncorhynchus mykiss) belong in the Salmonidae family which is native to North America but have been introduced to all continents apart from Antarctica. Its upper body is dark greeny blue, the sides are a lighter shade of olive green and blue and underneath their stomach is silvery-white. Their head and body are speckled and pink, red, or orange patches can appear along the rainbow trout’s head and/or flanks. Rainbow trout live in freshwater creeks, rivers, lakes, and dams. However, in the northern hemisphere some rainbow trout have been known to migrate between fresh and salt water for breeding. This is not the case in Australia though, as most are restricted to fresh water. Rainbow trout prefer cool waters of 10-22

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

The change in temperature affects the respiration of goldfish. In goldfish, active metabolic rate decreases as temperature is lowered (Johnston and Dunn 1987). The goldfish breathes per minute is decreased as oxygen is required for this activity. A similar experiment conducted supports the result from this experiment that oxygen consumption decreases as temperature decreases (Fry and Hart 1948). The decrease in breathes per minute was observed as the temperature was lowered. The average breathes per minute decreased from 110 to 92 per minute when the temperature was lowered from 22 to 12. So, the null hypothesis that the change in temperature will not affect the breathes of the goldfish was rejected. There were some sources of error for this

It consists of two gas-filled sacs found on the dorsal side of the fish (Bond, 1996). They are able to reach neutral buoyancy by controlling the amount of gas pressure. Most of them fill up their swim bladder with their pneumatic duct which is a link between their swim bladder and gut (Bond, 1996). They gulp air into their duct in order to fill it. When they gulp for air, the air goes through the gut and heads towards the swim bladder. The swim bladder is essential for tunas because it provides them with the ability to stay at a specific depth (Ramel, "Fish anatomy: The Swim Bladder"). If they want to change their depth, they would have to adjust their gas pressure. Certain amount of gas pressures can only maintain buoyancy for one

Sustaining fish can be a science. With regards to saltwater angle, this isn't different because encouraging saltwater fish can be dubious. There are certain principles to take after and rules that ought to be met.

They are not limited for feeding or breeding times. They are able to efficiently obtain oxygen from the water through their gill for gas exchange so that the fish can carry out respiration. Fish are able to constantly carry out gas exchange without any limitations using there adaptations, especially counter current flow. Fish are able to keep the gas exchange surface moist. The lamella mean the surface area to volume ratio is large and they have thin preamble cell walls. The distance is short because the walls of the lamella are very thin. However fish are limited to an aquatic environment. They are not able to survive on land because their gas exchange surface is external meaning it is prone to desiccation from the air. Gills are unable to extract oxygen from the air so gas exchange cannot occur. As a result respiration cannot occur and the fish

Surfboard fins, in fact, control the maneuverability and stability of your board. Without them, a surfboard's direction is at the mercy of the water's surface.

When fish are yanked from the water, they begin to suffocate. Their gills often collapse, and their swim bladders can rupture because of the sudden change in pressure. Numerous scientific reports from around the world confirm that fish feel pain. Researchers from the University of Edinburgh and University of Glasgow studied the pain receptors in fish and found that they were strikingly similar to those of mammals; the researchers concluded that “fish do have the capacity for
