Aerobic capacity influences the spatial position of individuals within fish schools.
The schooling behaviour of fish is of great biological importance, playing a crucial role in the foraging and predator avoidance of numerous species. The extent to which physiological performance traits affect the spatial positioning of individual fish within schools is completely unknown. Schools of juvenile mullet Liza aurata were filmed at three swim speeds in a swim tunnel, with one focal f...
متن کاملHigh performance individual-oriented simulation using complex models
Computational simulation has been used as a powerful tool to represent the dynamical behavior of systems based on complex analytic models. These types of models have two main drawbacks: a) limitations due to the degree of abstraction needed to simulate them, b) high computing power to simulate a heavily simplified models. The computing power available today can overcome these limitations to per...
متن کاملFish schools: an asset to corals.
Schools of juvenile haemulid fish feed in sea grass beds at night. By day they rest over coral heads, where they excrete substantial quantities of ammonium and particulate nitrogen and phosphorus into the nutrient-poor waters. The percentages of these nutrients contributed by the fish were comparable to those from other sources. Coral heads with resident fish schools grew faster than those with...
متن کاملDoppler structure in echoes from schools of pelagic fish
The frequency distribution of energy in direct path echoes from three schools of pelagic fish is preaented. One-half-second 30-kHz CW pulses were used to study motions internal to the fish schools from distance8 up to 1200 m. The measured Doppler spread of echo enagy ranged fmm 30 Hz to 70 Hz The Doppler spread-at-side aspect is related to swimming motions by a simple algebraic model based on B...
متن کاملMathematical modeling of space - time variations in acoustic transmission and scattering from schools of swim bladder fish ( FY 11 Annual Report )
The objective of this research is to develop a complete time-domain theory of acoustic scattering from, and propagation through, schools of swim bladder fish at and near the swim bladder resonance frequency, including multiple scattering and coherent interaction effects between the individual fish. This should then lead to a prescriptive capability for modeling the evolution of sound pulses as ...
