.... The purpose of the present study was to investigate the presence and possible role of OEA in feeding regulation in goldfish ( Carassius auratus ). We assessed whether goldfish peripheral tissues and brain contain OEA and their regulation by nutritional status. OEA was detected in all studied tissues (liver...

... such as fishes. To test this linear threshold shift hypothesis(LINTS) in fishes, we examined the effects of increased ambient sound on hearing of two species differing in hearing capabilities: goldfish( Carassius auratus ; a hearing specialist) and tilapia( Oreochromis niloticus ; a hearing generalist). Fish...

...) sounds on marine mammals, the effects of excess noise on fishes are poorly understood. We examined the short- and long-term effects of increased ambient sound on the stress and hearing of goldfish ( Carassius auratus ; a hearing specialist). We reared fish under either quiet(110-125 dB re 1 μPa) or noisy...

Conventional intracellular and patch-clamp recording techniques were used to record responses from excised ventricles or isolated ventricular myocytes and inside-out patches...

... Carassius auratus . Units of one class responded to a passing sphere and to the wake caused by that sphere with excitation. Units of the second class also responded to the moving sphere. However, these units did not respond to the wake behind the sphere. Hydrodynamic information received by class two units...

... this phenomenon is restricted to species that normally experience large fluctuations in external ion concentrations (e.g. moving from sea water to fresh water) or is present in a much wider range of species, we investigated olfactory Ca 2+ sensitivity in the goldfish ( Carassius auratus ), which is a stenohaline...

... to a 50 Hz vibrating sphere of single units in the medial octavolateralis nucleus (MON) in goldfish Carassius auratus . The MON is the first site of central processing of lateral line information. Three types of units were distinguished. Type I units ( N =27) were flow-sensitive; their ongoing discharge...

Bennett ABSTRACT Goldfish (Family Cyprinidae, Carassius auratus ) and killifish (Family Cyprinodontidae, Fundulus heteroclitus ) were acclimated to 10, 20 and 35 °C for 4 weeks. The thermal acclimation of C-start (escape swimming) performance and the physiological...

.... The mean gonadosomatic index (GSI) of experimental fish was 5.37±0.26 %. Comet goldfish ( Carassius auratus ) were reared in a private hatchery and transported to the Department of Zoophysiology, Uppsala University, 3 months before the start of the study. They were kept in 180 l aquaria at 14–16 ˚C...
