Likewise, some food ingredients, most noticeably fish meal or fish oil, can produce skin odor in dogs. Flatulence can be a problem for some dogs, which may be diet-related or a sign of gastrointestinal disease. This, in fact, may be the most commonly noticed source of odor from dogs fed cereal-based dog foods.
The entire system is a means of converting complex sensor responses into a qualitative profile of the volatile (or complex mixture of chemical volatiles) that make up a smell, in the form of an output. Conventional electronic noses are not analytical instruments in the classical sense and very few claim to be able to quantify an odor.
The detection system, which consists of a sensor set, is the "reactive" part of the instrument. When in contact with volatile compounds, the sensors react, which means they experience a change of electrical properties. [8] In most electronic noses, each sensor is sensitive to all volatile molecules but each in their specific way.
Pet owners are being warned to keep dogs away from dead fish after several cases of salmon poisoning were reported near Newport on the Oregon Coast.

A third study wanted to compare hatchery raised fish tolerance to copper versus naturally-reared fish to see if there is a plausible difference between the two species and their tolerance to copper levels in their system. They exposed naturally-reared steelhead (Oncorhynchus mykiss) to 5 and 20 μg/L for 3 hours. Based on their EOG readings the ...

Electric eel. As water is a much better electrical conductor than air, electrocommunication is only observed in aquatic animals. There are various animals that can detect electrical signals, but fish are the only aquatic animals that can both send and receive EOD, making them the only animals to effectively communicate using electrical signals.
