“…This result supports the hypothesis that the preferred feeding time is the time of day when feeding would yield the best growth performance (Heilman & Spieler, 1999). In general, predominantly diurnal fishes such as goldfish Carassius auratus L., grow better when fed during the photophase (Noeske et al, 1981;, and nocturnal catfish species have better growth performance when fed during the scotophase (Hogendoorn, 1981;Sundararaj et al, 1982;Boujard, 1995). Likewise, several studies have shown that rainbow trout grow most when fed at the peak of the preferred feeding phase (Reddy et al, 1994;Boujard et al, 1995;Gelineau et al, 1996).…”

The mean final weight of juvenile greenback flounder Rhombosolea tapirina fed a single daily meal during the scotophase was lower than that of groups fed continuously or fed twelve, six, three or one meal during the photophase. Final weight did not differ among the latter five groups. Size variation in all groups of fish decreased during the course of the trial over 120 days. Groups assigned to a higher frequency (and hence a longer total daily meal duration) of daily meals were less active during mealtime. A distinct food anticipatory effect was observed in the groups of fish receiving a single daily meal during either photophase or scotophase, and also developed before at least one meal in the group of fish fed three meals per day. 2001 The Fisheries Society of the British Isles

“…The feed consumption was not affected by the day light, because the walls of tank were painted with a grey paint and the aquarium compound was sparsely illuminated. The characteristic 'lazy' behaviour of the catfish may be beneficial for the culture results, because when they are satiated, they stay almost motionless at the bottom of the reservoir and thereby they do not loose unnecessarily their energy (Boujard 1995). Without any doubts, it exerts an influence on the use of the nutritive components of the feed, expressed by low FCR value (during the whole experiments, the mean FCR value was one).…”

“…17 Annual or seasonal changes are often predictable because they are closely correlated with other environmental factors, namely water temperature and day length. Most cold-water fish (eg, Arctic char, rainbow trout, Atlantic salmon, and turbot) [19][20][21][22][23] and warm-water fish (eg, European sea bass, catfish, and goldfish) [24][25][26][27] cultured under ambient water temperatures with access to natural light and photoperiods typically increase their feeding behavior in the spring and throughout the summer months when the days are longer and water temperatures higher. They gradually reduce feeding in the autumn and into the winter months as water temperatures fall and day length decreases.…”

Nutrition and feeding influence growth, reproduction, and health of fish and their response to physiologic and environmental stressors and pathogens. The basics of fish metabolism are similar to those of warm-blooded animals in that they involve food intake, digestion, absorption, and transport of nutrients to the various tissues. Fish, however, being the most primitive form of vertebrates, possess some distinguishing features, such as the absence of a stomach in certain species, lack of mandibular teeth, and nondifferentiated small and large intestines. Some major physiologic and metabolic differences between other vertebrates and fish include the mechanisms involved in intestinal cell wall absorption by pinocytosis, metamorphosis in larval fish development, and the shift in osmoregulation in salmonids during sea water adaptation, carbohydrate metabolism, nitrogen excretion, and skeletal development. Unlike warm-blooded animals, which are homoeothermic, fish are poikilothermic, so their body temperature and metabolic rate depends on the water temperature. Environmental temperature influences energy expenditure and nutrient intake. At low temperatures, the cell membranes of fish remain fluid because of the incorporation of high amounts of polyunsaturated fatty acids from dietary fish oils and other lipid sources. Many fish efficiently use protein and lipid for energy rather than carbohydrates. Fish are also unique among vertebrates in their ability to absorb minerals not only from their diets but also from water through their gills and skin.
