Unlike humans, fish do not have lungs (with the exception of one species, the "lung fish"). Fish are in fact not "ventilating", but breathing. Inside the gills of a fish are rows of red tissue, called filaments. Inside the filaments are many blood capillaries rich with red blood cells which transport oxygen throughout the body. As the fish moves its gills back and forth, it moves water over the filaments and oxygen in the water is absorbed into the blood stream through the filaments. When fish are in water with too little oxygen and cannot get what they need from moving their gills, they will go to the top of the water and gulp air from the surface. If you own a fish and you see it doing this, it would be a good idea to install a water filtration system. Fish will die if the water they are in has too little oxygen.
They also have to vibrate their gills from time to time to release the build-up of sea salt, which can become carcinogenic if allowed to cake hard.

What is the Function of the urinary bladder of the fish?
The urinary bladder is situated behind the Vent (Anus) on the fish. Just as it is on humans, it is there to release any unwanted waste from the body. Fish have two bladders, one is a swim bladder and the other is the urinary bladder. Do not get these mixed up. The swim bladder allows the fish swim in different densities of water and the urinary bladder is to pass urine. Fish do not use urea to get rid of their nitrogen like mammals do, but instead use NH3 Ammonia.

How do you know if a walleye fish is a female or male?
This is very difficult. It's done through "venting." The vent is the opening between the anus and the anal fin where the fish will excrete either eggs or sperm. Usually the vent is larger in females. It raelly just depends on the type. In some cases, if there is an "egg spot" on their anal fin, it means that the fish is male.

How do you vent Oscar fish?
To Vent an Oscar you must first remove it from the tank and turn it over onto it's back so it is belly up. You must then examine the Vent. The Vent is the opening between the anus and the anal fin. This is where the male fish release their sperm and the female fish release their eggs. This area is also known as the genital papilla. The female's Vent will be larger than the males to accomadate the passing of the eggs. Unless you have one of the opposite sex for comparrison it will be difficult to determine sex for the unexperienced hobbyist. It will also prove to be more difficult with younger fish rather than more mature fish. For sexually monomorphic fish species (females and males look alike) Venting is the most accurate form of sex determination.
