“…Flavours bitter to humans provoke response in rainbow trout when measured electrophysiologically (Hara 1994). Some o¡-£avoured feed ingredients or additives reduced the feed intake of salmonids, as reported with drugs (Schreck & Mo⁄tt 1987;Hustvedt, Storebakken & Salte 1991;Toften, Jrgensen & Jobling 1995) or oxidized oil (Ren 1999).…”

The objectives of the study were to investigate the effect of a feeding stimulant on feeding adaptation of gibel carp (Carassius auratus gibelio Bloch) fed diets with replacement of ¢sh meal by meat and bone meal (MBM), and whether or not the juvenile gibel carp could adapt to higher MBM level in the diet. Juvenile and adult gibel carp were tested. Two and one replacement levels were used for juvenile and adult ¢sh respectively. Each group of diets was set as two types with or without a unique rare earth oxide: Y 2 O 3 , Yb 2 O 3 , La 2 O 3 , Sm 2 O 3 , Nd 2 O 3 or Gd 2 O 3 (only the ¢rst four rare earth oxides were used in adult diets) for four adaptation periods of 3,7,14 and 28 days respectively. After mixing, an equal mixture of all six diets for juvenile or four diets for adult was o¡ered in excess for 2 days. During the last 2 days of each experiment, no feed was o¡ered and faeces from each tank were collected. Feeding preference was expressed as relative feed intake of each diet, which was estimated based on the relative concentration of each marker in the faeces.Given some adaptation period, such as 3^28 days, the e¡ects of MBM and squid extract inclusion on the preference to each diet were reduced. After 28 days adaptation, the preferences between groups were not signi¢cantly di¡erent.

“…We stress that these hypotheses should be rigorously tested, especially that we did not detect significant effects of predation cues on the attachment strength. It is unlikely that the responses predicted by the HIMES are effective against bird predation, but they should be effective in confrontations with other predators, such as crustaceans and fish, which have the physiological capacity to localize zebra mussels based on chemical information (Atema, 1980;Hara, 1994;Lee & Meyers, 1996). In fact, experiments on crayfish show that these predators use chemical detection to sense dead (Hazlett, 1994) and living zebra mussels (Czarnoleski et al, 2011).…”

Sedentary prey facing an acute predation risk: testing the hypothesis of inducible metabolite emission suppression in zebra mussels, Dreissena polymorpha

It takes time before a defensive phenotype can be effectively developed, which handicaps sessile bivalves exposed to acute predation risks. In a laboratory experiment, we examined whether predation threats induce zebra mussels to limit metabolic rates, serving as a fast-response defence that reduces the chances of chemical detection by predators. We measured the respiration rate of mussels exposed to predation treatments (fish fed zebra mussels, fish fed chironomids, crushed zebra mussels) and to predationfree conditions, and we tested the effect of these treatments on attachment strength and aggregation. Compared with the predation-free controls, all mussels in the predation treatments tended to initially have suppressed metabolic rates. The rate of metabolism increased over time in all treatments, but only in the presence of fish fed chironomids was the increase significantly greater than in the control. Attachment strengths and aggregation rates were similar for all treatments after 7 days. Our results provide the first evidence of predation-induced changes in zebra mussel metabolic rates. We suggest that mussels respond differently to different types of predation threats. Immediately after receiving predation cues, they react promptly by lowering their production of metabolites, but over time, they re-adjust their response to the actual predation threat present.

“…Spectral analysis of EEG suggested that the home water stimulant(s) was absorbed on activated carbon and ionexchange resin, insoluble in petroleum-ether, dialyzable, nonvolatile, and heat-stable (Ueda, 1985). Chemicals which elicit the response from the olfactory receptor cells are amino acids, steroids, bile acids, and prostaglandins (Hara, 1994). The chemical composition of freshwater odorants that allow salmon to discriminate the natal river are now investigating in our laboratory, and our recent study suggests that amino acids are one of the important components for the determination of various freshwaters.…”

“…These studies examined the magnitude of EEG or differences of frequency spectrum as the exclusive parameter. Although the maximum magnitude of EEG was used as the index of the response to the odor of natal stream water, these magnitude has been considered to be independent of the recognition of natal stream water (Hara, 1994). Bodznick (1975Bodznick ( , 1978a recorded the EEG responses and the single olfactory bulb unit response in juvenile sockeye salmon (Oncorhynchus nerka) indicating that these responses showed the different properties to natural water and amino acids.…”

ABSTRACT-In order to study the olfactory discriminating ability of lacustrine sockeye salmon (Oncorhynchus nerka) and masu salmon (O. masou), the integrated olfactory nerve response to various freshwaters was recorded by electrophysiological techniques. In both species independent of sex and gonadal maturity, each freshwater caused a different olfactory response. Source and effluent waters of the culture pond at Toya Lake Station (the source and culture pond waters) evoked the minimum and maximum response magnitude, respectively. In cross-adaptation experiments, the culture pond water abolished all secondary responses to other freshwaters, and no freshwater abolished the secondary response to the culture pond water. The concentration response study revealed that the minimum concentration (threshold) to induce response to the culture pond water after adaptation to Lake Toya water was between 0.1 and 1.0%. The present study indicates that the olfactory organ of lacustrine salmonids may discriminate different intensities of various freshwater odors.
