To urinate, if you mean the urinary bladder. If you mean the swim bladder, it is to be able to change its depth in the water. It has a way to vent air from the gills to the swim bladder, and from the swim bladder to the digestive tract. So the fish would inflate the bladder to be able to rise and deflate the bladder to go lower.
A fish controls its depth by increasing or decreasing the amount of air in its swim bladder. When a fish has more air in the swim bladder, it is more bouyant and rises to the surface ,but when it lets out the air and the swim bladder fills with water, it becomes less bouyant so the fish sinks.
Increases the fish's volume by filling the swim bladder with oxygen.
Increases the fish's volume by filling the swim bladder with oxygen.
no, they have a swim bladder but this is so the fish can stay afloat
The swim bladder makes your fish sink so it isn't floating to the top of the tank.If your fish is floating then it might be a swim bladder problem.Or your fish is dying.
No, the swim bladder is not contagious. It is an internal organ found in some fish that helps them control their buoyancy in water.
swim bladder is what helps the fish stay afloat without the swim bladder a fish would simply sink duhhh
they have an organ called a swim bladder. It is filled with gas and it keeps them afloat.
A ballon because when you blow it up with air it floats like a fish bladder and when you let out the air it sinks like a fish bladder.
No, swim bladder disease is not contagious to other fish. It is a condition that affects an individual fish's swim bladder, which helps control buoyancy.
Fish that lack a swim bladder include many species of bottom-dwelling fish, such as catfish and many species of eels. Additionally, some deep-sea fish and certain types of flatfish, like flounders and soles, also do not possess a swim bladder. Instead of relying on a swim bladder for buoyancy, these fish often have other adaptations that help them maintain their position in the water column or reduce their density.
Going UpSwim bladders are located in the center of a fish's body in order to help the fish's balance and swimming ability. According to the book "Goldfish", some fancy goldfish like the lionhead are poor swimmers because their swim bladder is located too far forward. When the fish wants to go up, a pneumatic duct opens to let in oxygen to swell the bladder up like a little balloon. By gulping, the fish can help fill up the bladder. Some fish, like the rudd, have two swim bladders.Going DownWhen the fish wants to swim lower, they deflate their swim bladders. The gas is absorbed into their gas glands, which are located on either side of the swim bladder. The fish's body can also use the gas glands to help inflate the swim bladder. Fish can also expel excess gas from their mouths in something similar to a belch. Also, if fish are caught in oxygen-poor water, they can use some of the oxygen in the gas glands or swim bladder to help them breathe. According to the Encyclopedia Britannica, some of fish species like sharks use oil instead of gas to inflate or deflate an area in the liver, since oil is lighter than water.Going the Wrong WayIf a fish is swimming sideways, is unable to rise to the surface or is clearly having trouble swimming, chances are it is due to swim bladder disorder. If a fish is constipated, this could press the digestive organs against the swim bladder, not allowing it to inflate properly. According to HealthyBetta.com, a fish that has swim a bladder disorder should go on a fast for a day and not be fed so much in the future. Also, splitting the feedings to two or three a day is better on the swim bladder than one large feed per day.
