Not smell, as in release an odour. But, smell, as in the sense of smell.

Yes they can detect tiny chemical traces in the water.
Fish use chemoreception to smell and taste as humans do. In many fish, these senses are even further developed than those of humans, and many species are dependant on the to detect prey. Most fish have two nostrils, one on either side of their head not attached to the throat, but contain an olfactory organ used to detect chemicals. The size of this organ is normally proportional to the fish's sense of smell; the larger the nostril the better the sense of smell. Many higher species of fish, such as sharks, can sense chemicals in the water with a concentration as low as one part per billion!
Most fish also possess the ability to taste. As humans do, fish possess taste buds. However, fish possess many more, those of which are much more accurate. Taste buds line not only the tongue, but the entire mouth as well. Some species of fish, such as the catfish, possess special structures called barbels. These barbels are whiskers that have taste structures allowing fish the dig for food, tasting it before it even reaches their mouths.

Some fish have an incredible sense of smell. I can add a single 1mm food pellet in my 125gal tank and within 10secs my african cichlids go into a feeding frenzy in search of food.
Some fish have a greater sense of smell than others (catfish have a superb sense of smell).

sure they do. Salmon locate there some time past to the river of their delivery via the experience of scent. Sharks can discover blood from miles away. canines have a feeling of scent 1000 cases that of a human. Fish have a feeling of scent 1000 cases extra helpful then a canines.

Yes, they do. Most also are able to detect "smells" via sensory organs situated along the lateral line.

Yes, i think so as when you go fishing you can put in stuff that dissolves in the water and attracts fish.
