From small fish to big fish, every species has unique lips and mouth. Some are pointed upwards and others down, while some are lined with sharp teeth while others are designed to crush. Most popular aquarium fish have a terminal mouth that is relative to their body size, but others need ...
Fish are boney, and ornamental pond fish are no exception, as you’ll see in the pond fish anatomy diagram. Unlike the bones of sharks and stingrays, their bones are truly bones and not cartilage. The bones of a fish are not meant for bearing weight because, in water, the fish is pre...
A diagram of a ctenoid scale up close (Photo Credit : Morphart Creation/Shutterstock) Conclusion: Scales not only form the exoskeleton of different fish, but also help in classification. Moreover, apart from these types, the other body parts of some fish represent slight modifications of these...
A fish body size calculation device includes an imaging device that images a moving fish in water and an analysis device that performs arithmetic processing for calculating the actual size of the fish. The analysis device recognizes the fish body shape (sideways state) of the migratory fish from...

Fig. 14.Schematic diagram of feeding method based on passive acoustics. The machine vision-based method refers to using machine vision technology to obtain the physiological information of the fish and the feeding demand information. Then, the feed feeding is controlled based on the analysis results...
