All fish and all animals need to bring oxygen to the cells. The oxygen is a major portion in the production of something called ATP. ATP is the actual little energy 'battery' that each cell needs to function.
No but the cells that fish are made of do.
since fish live in water and it face some problems in ventilation where it getoxygen from water where oxygen concentration of oxygen in water is small hence large amount of water must pass to the gills so as to supply sufficient oxygen for metabolic activities on doing that fish use more energy since water is very viscous which make it not easily to flow in the gill so fish use more energy to over come this friction
Fish are like humans in the way that they need oxygen. Fish breathe in dissolved oxygen and pass out carbon dioxide.
which have a better chance to be fertilized the egg cells of fish or the eggcells of frogs
Blood transports oxygen nutrients and wastes in mammals and fish .
Gills carry oxygen fish need directly from the water
Yes, they do. Fish do not need to create urea or uric acid in order to excrete their wastes because they live in water, they can simply excrete the waste out of their gills, which requires less energy than having to create uric acid etc.
To incease the surface area of the gills so more oxygen can be diffused from the water the fish swims in into there bloodstream where the oxygen can be carried the fish's cells for cellular respiration
probably to facilitate diffusion of molecular oxygen from the air into the fish's bloodstream
Besides interfering with oxygen transfer on its' gills the salt water will cause the cells of the fish to retain fluid making the pressure within the cells greater than the pressure outside the cells. Ideally the water a fish swims in will keep its' body in homeostasis where the pressure both inside and outside the cells of the body is equal.
Between 55F and 65F is good. When the water goes over 65F and up to 70F the fish are likely to come into breeding mode. Over 70F and the fish will be prone to shortage of oxygen and may burn out through an increase in their metabolic rate.
they run the water thru their gills while the special cells in their gill collect the oxygen molecules from the water.
fish swim for oxygen.

most fish get their air from the oxygen-saturated water, but certain breeds (like bettas) do well in water with a low amount of dissolved oxygen, because they have a special resperatory organ called the labyrinth that allows them to breathe at the waters surface- in fact, they inherently must do so... unless they want to go to fishie heaven :(
