“…FAA has been demonstrated in many vertebrates including fish so that a number of fish species are able to anticipate a single daily meal (Spieler, 1992;Gee et al, 1994;Naruse and Oishi, 1994;Sanchez-Vazquez et al, 1995bBolliet et al, 2001;Purser and Chen, 2001), and some fish species are capable of anticipating two (Reebs, 1999;Lague and Reebs, 2000;Chen and Tabata, 2002;Heydarnejad, 2008) or three daily meals (Reebs, 1996;Azzaydi et al, 1998). It has been shown that, at the group level, rainbow trout are able to demonstrate FAA by anticipating a single daily meal (Bolliet et al, 2001).…”

“…Thus, detection of FAA depends on the way it is measured (Mistlberger, 1994;Pecoraro et al, 2002). Purser and Chen (2001) in researching the combined effect of meal size and meal duration in greenback flounder, found an inverse correlation between magnitude and duration of FAA and meal duration, for each of three meal sizes tested. It is thought that FAA is regulated by a food-entrainable circadian oscillator (FEO), which in rats is anatomically and functionally distinct from the LEO (Edmonds and Adler, 1977;Stephan et al, 1979;Clarke and Coleman, 1986).…”

Using two methods of food delivery, defensible (D) and indefensible (ID), the effect of restricted feeding (RF) on the development of feeding anticipatory activity (FAA) and growth performance of rainbow trout (Oncorhynchus mykiss) was investigated. Six glass aquaria (120 × 30 × 80 cm), divided equally into 3 sections of morning, afternoon and evening of location of food delivery each with eight fish were selected for D and ID methods. The fish were subjected to a time-RF schedule for 70 days. Food delivery was restricted to three feeding periods; one hour per feeding session: morning (0800-0900 h), afternoon (1300-1400 h) and evening (1800-1900 h). Food was withheld on days 28, 42, 56 and 70 (test days) to assess FAA by the fish and fish growth parameters were determined at the end of the experiment. The present results clearly indicate that only using an indefensible (ID) pattern of food delivery, rainbow trout can simultaneously anticipate three daily meals and synchronise their feeding activity before the period of food availability and that the best FCR and SGR were achieved when an ID pattern of food delivery was offered. The lack of development of FAA for fish in the D method could be due to development of dominant hierarchies. This led to reduction of most growth parameters in the D method compared to the ID one.

“…This was supported by the facts that almost all greater amberjack demanded actively for feed only for 1–3 h out of the light phases, and appetite seemed to be satisfied as 4·51% pellets were uneaten. Purser & Chen (2001) reported that a single daily meal with larger meal size and longer meal duration acted as a weaker synchronizer in greenback flounder Rhombosolea tapirina Günther. Although it is impossible to distinguish the respective role of the LD cycle and feed‐fast cycle as a synchronizer to entrain endogenous circadian oscillators in the greater amberjack, the loosely restricted feed‐fast cycles may be at best a weaker synchronizer than the LD cycles to entrain self‐feeding rhythms in the present study.…”

In the present study, 10 greater amberjack Seriola dumerili held individually were given free access to self-feeder, and trigger actuations were continuously monitored. Most (80%) of greater amberjack developed stable self-feeding activity within 1 week. The fish was a rigidly diurnal feeder under a 12L:12D cycle, with a feeding peak of 1-3 h occurring just after the onset of lights. Under constant conditions, all 10 individual fish exhibited free-running self-feeding rhythms, which persisted for 43 days without a sign of damping out. As far as is known, this seems to be the longest record of free-running behavioural rhythms in fishes. Except one fish free-ran at a period length (t) of 25Á2 h, t of free-running self-feeding rhythms in the other nine fish was shorter than 24 h, ranging from 20Á0 h to 21Á5 h. In addition, phase transients of feeding activity were observed in response to the advancement of lights on. It is concluded that feeding activity in greater amberjack is mediated by endogenous circadian oscillators. # 2007 The Authors Journal compilation # 2007 The Fisheries Society of the British Isles

Individual rainbow trout can learn and anticipate multiple daily feeding times

The present study was conducted to investigate whether individual rainbow trout Oncorhynchus mykiss can simultaneously anticipate two daily meals, and to evaluate the influence of time-restricted feeding schedules and light-dark (L : D) cycles on the timing of self-feeding activity. Individual rainbow trout were capable of anticipating not only a single meal but also two daily meals scheduled at different times; the duration of anticipation was short and precise. This seems to be the first convincing evidence to show that a single fish can simultaneously anticipate two daily meals. Change in the onset and cessation of light did not affect the duration of food-anticipatory activity, although it led to shift the phases of the light-related self-feeding activity. Moreover, under constant light and ad lib feeding conditions, only one band of rhythmic activity was observed in individual rainbow trout that had previously developed food-anticipatory activity to each of the two daily meals.
