Montgomery JC, Coombs S, Baker CF (2001) The mechanosensory lateral line system of the hypogean form of Astyanax fasciatus. Env Biol Fish 62:87–96 The study of fishes, the science of ichthyology, is of broad importance. Fishes are of interest to humans for many reasons, the most important being their relationship with and dependence on the environment. A more obvious reason for interest in fishes is their role as a moderate but important part of the world’s food supply. This resource, once thought unlimited, is now realized to be finite and in delicate balance with the biological, chemical, and physical factors of the aquatic environment. Overfishing, pollution, and alteration of the environment are the chief enemies of proper fisheries management, both in fresh waters and in the ocean. (For a detailed discussion of the technology and economics of fisheries, see commercial fishing.) Another practical reason for studying fishes is their use in disease control. As predators on mosquito larvae, they help curb malaria and other mosquito-borne diseases. Shupak A. Sharoni Z. Yanir Y. Keynan Y. Alfie Y. Halpern P. (January 2005).

Place your fly upstream and within the binocular zone (a 30–36° angle) of a position-holding trout. Senses of smell and taste are well developed in fish, and there are many applications of that information in formulating artificial feeds and baits for fishing. Nilsson, G. E. 1996. Brain and body oxygen requirements of Gnathonemus petersii, a fish with an exceptionally large brain. Journal of Experimental Biology 199:603–607. Fish utilize the lateral line to detect movements of prey, predators, currents, and objects in the water. If there is any difference between the relative movements of the body of the fish and the movements of the surrounding water, it will be sensed by the lateral line (Mogdans 2019). In this way, the fish knows if it is swimming in highly turbulent or still waters. The lateral line is also very sensitive to water vibrations from great distances underwater, so this sixth sense is sometimes called the far-field hearing (Figure 3.5).

Sensory ecology focuses on the study of animal sensory systems to understand how environmental information is perceived, how this information is processed, and how this affects interactions between the animal and its environment (Dangles et al. 2009). The stimulus-response model (Figure 3.2) describes the basic reactions from the stimulus, through receptors to the central nervous system and brain, which are then transmitted to neurons and organs that respond due to detection of the stimulus. A stimulus is any change in the environment (either external or internal) that is detected by a receptor. It may be a predator threat, an easy prey item, or a potential mate. Receptors transform environmental stimuli into electrical nerve impulses. These impulses are then transmitted via neurons to the central nervous system and brain where decision making occurs. When a response is selected (consciously or unconsciously), the signal is transmitted via neurons to effectors. Effectors are organs (either muscles or glands) that produce a response to a stimulus. A response is a change in the organism resulting from the detection of a stimulus.
