“…FAA has previously been described in several fish species, including goldfish, European sea bass, golden shiner, tench, and zebrafish (Azzaydi et al, 2007;Herrero et al, 2005;Reebs & Lague, 2000;Sánchez-Vázquez & Madrid, 2001). In fish, FAA persisted under restricted feeding and constant conditions of illumination in tench Note.…”

Food provided on a periodic basis can act as a potent synchronizer, being a stronger zeitgeber than light for peripheral oscillators in mammals. In fish, however, little is known about the influence of feeding time on the circadian pacemaker and the relationship between central and peripheral oscillators. The aim of this research was to investigate the influence of mealtime on the activity rhythms, and on central (brain) and peripheral (liver) oscillators in zebrafish. The authors tested different feeding times under a light-dark (LD) cycle and the endogenous origin of food-anticipatory activity (FAA) by feeding zebrafish at a fixed time under constant bright-light conditions (LL). The authors then measured locomotor activity and the expression of the clock gene per1 in animals under a LD cycle and fed at random times during the light phase, with restricted feeding at the mid-light phase (ML) or with restricted feeding during the mid-dark phase (MD). Finally, the authors measured locomotor activity and per1 expression in fish maintained under LL under either random feeding or scheduled feeding. Zebrafish displayed FAA in all the groups fed at a fixed time but not when feeding was randomly scheduled. Under LL, fish entrainment persisted, and when released under fasting conditions FAA free-ran with a circa-24-h period. The expression of per1 in the brain of fish under LD showed a daily rhythm with the acrophase (peak time) at the end of the dark phase regardless of feeding schedule. This brain rhythm disappeared in LL fish under both random feeding and scheduled feeding. Feeding at MD advanced the phase of per1 in the liver by 7 h compared with the ML-fed group phase (23:54 versus 07:23 h, respectively). In addition, under LL scheduled feeding entrained the rhythms of per1 expression in the liver. This study reveals for the first time that scheduled feeding entrains peripheral oscillators in a fish species, zebrafish, which is a powerful model widely used for molecular genetics and for the study of basic clock mechanisms of the vertebrate circadian system.

“…The ability to learn to associate a specific time and place with a food reward has been confirmed in many species, e.g. insects, fishs, birds and mammals (Beling, 1929;Moore et al, 1989;Biebach et al, 1991;Mistlberger et al, 1996;Carr and Wilkie, 1997;Marchant and Mistlberger, 1997;Reebs and Lague, 2000;Aragona et al, 2002;Pizzo and Crystal, 2002). Many studies have also demonstrated diurnal differences in the ability of animals to acquire or recall a memory task.…”

mPer1 and mPer2 mutant mice show regular spatial and contextual learning in standardized tests for hippocampus-dependent learning

Summary. Learning and memory, like most physiological processes, seem to be under the control of circadian rhythm. The recently cloned mPer1 and mPer2 genes play an important role in the regulation of the circadian rhythm. In this study, we tested mPer1 and mPer2 mutant mice in two different learning and memory paradigms, a water-maze place navigation task and contextual fear conditioning. In both learning tests, the hippocampus is critically involved. None of these learning types were affected by the mutations, suggesting that mPer1 and mPer2 do not play a major role in the regulation of hippocampusdependent learning and memory.

“…Evidence of food anticipatory activity has been found in many species including rodents, bees, fi sh, birds, rabbits, carnivores, and primates (for review see Carlstead, 1986;Mistlberger, 1994;Azzaydi et al, 1998;Reebs and Lague, 2000;Vinke et al, 2004;Ulyan et al, 2006;Waitt and Buchanan-Smith, 2006;Bassett and Buchanan-Smith, 2007;Gilbert-Norton et al, 2009;Mistlberger, 2009Mistlberger, , 2011). Yet, there is only one study that reports the presence of FAA in dolphins before they participate in feeding or training sessions (Jensen et al, 2013).…”

This study examines whether a group of captive false killer whales ( Pseudorca crassidens ) showed variations in the vocal rate around feeding times. The high level of motivation to express appetitive behaviors in captive animals may lead them to respond with changes of the behavioral activities during the time prior to food deliveries which are referred to as food anticipatory activity. False killer whales at Qingdao Polar Ocean World (Qingdao, China) showed signifi cant variations of the rates of both the total sounds and sound classes (whistles, clicks, and burst pulses) around feedings. Precisely, from the Transition interval that recorded the lowest vocalization rate (3.40 s/m/d), the whales increased their acoustic emissions upon trainers' arrival (13.08 s/m/d). The high rate was maintained or intensifi ed throughout the food delivery (25.12 s/m/d), and then reduced immediately after the animals were fed (9.91 s/m/d). These changes in the false killer whales sound production rates around feeding times supports the hypothesis of the presence of a food anticipatory vocal activity. Although sound rates may not give detailed information regarding referential aspects of the animal communication it might still shed light about the arousal levels of the individuals during diff erent social or environmental conditions. Further experiments should be performed to assess if variations of the time of feeding routines may aff ect the vocal activity of cetaceans in captivity as well as their welfare.
