The present study investigated behavioural responses of naı¨ve rainbow trout Oncorhynchus mykiss, lake charr Salvelinus namaycush, lake whitefish Coregonus clupeaformis and goldfish Carassius auratus to food extracts as well as selected amino acids (at 10 À6 M) and related chemicals in a flow-through behaviour trough. Cysteine, the most potent olfactory stimulating amino acid determined electrophysiologically, enhanced locomotor activity, an initial arousal behaviour, in all species examined, in exactly the same fashion as did food extracts. The increased locomotor activity was followed by distinct species-specific search behavioural patterns: 1) bottom searching in rainbow trout; 2) surfacing and jumping in lake charr; 3) exploratory behaviour against the trough window in lake whitefish; 4) gravel pecking in goldfish. Olfactory-stimulating neutral amino acids alanine and serine and gustatory-stimulating imino acid proline were effective, to varying degrees, in eliciting feeding behaviour. Arginine and glutamate suppressed the locomotor activity in rainbow trout, but triggered feeding behaviour in the other species. Agmatine, a decarboxylated arginine, stimulated feeding behaviour in all species tested, except rainbow trout. The observed behavioural responses were in close accordance with the electrophysiological threshold and specificity. Together, the present data demonstrate that single amino acids and closely related chemicals initiate feeding behaviour primarily by olfaction, and interchangeably and complemented by gustation, in naive fishes.

“…Quite a few studies conducted with feeding stimulants for fish previously, but these were short‐term trials (Kohbara et al, ; Mackie & Adron, ; Xue & Cui, ); nevertheless, the long‐term feeding trails were efficient ways to demonstrate the effect of a feeding stimulant. Studies have been demonstrated that feeding stimulants decreasingly effective under lengthy feeding, particularly when feeding at high levels (Kamstra & Heinsbroek, ).…”

Effect of feeding stimulants on growth performance, feed intake and appetite regulation of mandarin fish,Siniperca chuatsi

Mandarin fish is a typical carnivorous fish, it can accept artificial diet after domestication, which is significantly essential to optimize its artificial diet. Nevertheless, only few studies were conducted on artificial diet of mandarin fish. Therefore, an 8-week feeding trial was conducted to evaluate the influence of feeding stimulants on growth performance, feed intake and appetite regulation of mandarin fish. In this trial, six diets were formulated, a basal diet contained 80% of Fish Meal without feeding stimulants, named as Control, 0.4% inosinic acid meal, 0.4% L-Alanine meal, 3%Yeast meal, 3% a commercial squid extract meal and 0.4% betaine meal were added into the basal diet to make five experimental diets, which were named as IM, AM, YM, SVO and BM respectively. At the end of feeding trial, SVO group showed higher feed intake, up-regulated mRNA expression of neuropeptide Y (NPY) and down-regulated mRNA expression of pro-opiomelanocorticoid (POMC) significantly as compared to control group, which suggested that squid extract improved feed acceptability and promoted appetite in mandarin fish. Similarly, compared to control group, SVO group showed low food conversion ratio, high weight gain and SGR, indicated that squid extract enhanced the growth performance. Our results suggested that the appropriate level of squid extract addition could contribute to optimize artificial diet in mandarin fish.

“…According to the gustatory response spectra for amino acids examined electrophysiologically, fish fall into two principal groups: one responds well to many different types of amino acids having a wide response range, and another responds to a few types of amino acids within a narrow response range spectrum (Hara 1994). Among the marine fish, red sea bream Chrysophrys major (Temminck and Schlegel) (Goh & Tamura 1980), mullet Mugil cephalus L. (Goh & Tamura 1980), tigerfish Therapon oxyrhynchus (Temminck and Schlegel) (Hidaka & Ishida 1985), jack mackerel Trachurus japonicus (Temminck and Schlegel) (Ishida & Hidaka 1987), chub mackerel Scomber japonicus (Houttuyn) (Ishida & Hidaka 1987) and marbled rockfish Sebastiscus marmoratus (Cuvier) (Kohbara, Oohara, Masuda, Hidaka, Takii & Kumai 2002) belong to the former group. On the other hand, puffer Takifugu pardalis (Temminck and Schlegel) (Kiyohara, Hidaka & Tamura 1975), yellowtail Seriola quinqueradiata (Temminck and Schlegel) (Hidaka, Ohsugi & Yamamoto 1985; Hidaka, Zeng & Kohbara 1992) and amberjack S. dumerili (Risso) (Ishida & Hidaka 1987) belong to the latter.…”

“…Interestingly, the pelagic migratory species, yellowtail, amberjack and the Pacific bluefin tuna, are all included in the latter group. Furthermore, Hidaka, Nyu and Kiyohara (1976); Goh and Tamura (1980); Hidaka and Ishida (1985); Ishida and Hidaka (1987) and Kohbara et al (2002) pointed out that the taste response to Gly would be an appropriate index of the feeding habits of fish. For example, some coastal species, such as puffer, red sea bream, tigerfish and marbled rockfish, are highly sensitive to Gly.…”

Gustatory neural responses of the Paci¢c blue¢n tuna Thunnus orientalis (Temminck and Schlegel) to extracted compounds of prey organisms, such as amino acids, nucleotide-related substances, organic acids and organic bases, were electrophysiologically recorded from the facial nerve supplying the anterior palate. Of the17 amino acids tested, L-proline was the most potent amino acid at 10 À2 M, and its threshold was the lowest at around 10 À 6 M. L-leucine, Lmethionine, L-alanine, L-valine and L-isoleucine were also highly stimulatory at 10 À2 M; however, the other 11 amino acids examined were not as e¡ective or were ine¡ective. Thus, the gustatory receptors for amino acids of the Paci¢c blue¢n tuna show a narrowly tuned response pro¢le. Among the seven nucleotide-related substances tested, uridine-5 0 -monophosphate, inosine-5 0 -monophosphate and adenosine-5 0 -diphosphate were highly stimulatory, and their thresholds were 10 À 4^1 0 À5 M. Inosine elicited a positive response at10 À2 M but its response magnitude was not so high. Organic acids L-lactic and pyruvic acids were e¡ective at 10 À2 M, but no response was elicited at 10 À3 M. Among organic bases, betaine was highly stimulatory, and its response magnitude at 10 À2 M is almost equal to that of L-proline at the same concentration. The threshold for betaine was determined to be at around 10 À5 M. Trimethylamine oxide and ammonium chloride were ine¡ective.
