potentials of sugars and related compounds have been statistically estimated in
an olfactometer on the basis of exploratory and feeding behavior in oriental
weatherfish, Misgurnus anguillicaudatus
(Harada et al., 1994). Six monosaccharides, three disaccharides, six sugar
alcohols, six glycosides and two artificial sweeteners have been tested. Among
them, fructose, glycyrrhizin, aspartame and rebaudioside, especially the last, show
the higher attractivity. Using the
same technique, Harada et al. (1995) have studied the attractivity of the
foregoing sugars and related compounds for yellowtail, Seriola quinqueradiata, discovering that galactose, maltose and glycyrrhizin are highly
attractive for this fish.
Somewhat earlier, Rottiers &
Lemm (1985) have found that juvenile
walleyes, Stizostedion vitreum, are
attracted by sucrose solution in the Y-shaped olfactometer.
important to underline that olfactory responses of fish do not correlate with
their gustatory, first of all intraoral responses to the same substanses (Kasumyan
& Døving, 2003;
Hara, 2006). In carp, Cyprinus carpio,
for example, amino acids (alanine, valine and leucine) most attractive in the
olfactometer experiments (Saglio et al., 1990) are not matched with amino acids
(cysteine, proline, glutamic and aspartic acids) most attractive as ingredients
in the palatable agar-agar pellets (Kasumyan & Morsi, 1996; see also Wood & Azócar,
Sucrosa is an
indifferent gustatory stimulus for carp (Kasumyan & Morsi, 1996).
to Kasumyan & Døving (2003) and Isaeva (2007),
sucrosa as gustatory stimulus is also indifferent for many other cyprinid (Cyprinidae)
fish such as tench Tinca tinca, bitterling Rhodeus sericeus amarus, lake bleak Leucaspius delineatus, crucian Carassius carassius, goldfish Carassius auratus, chub Leuciscus
cephalus, European minnow Phoxinus
phoxinus and bream Abramis brama,
in the experiments with the agar-agar pellets. Sucrosa as gustatory stimulus is
only positive for roach Rurilus rutilus,
grass carp Ctenopharyngodon idella as
well as for guppy Poecilia reticulata
& Døving, 2003)
which eat the most large amount of vegetable food.
to Chervova & Lapshin (2005), external parts of
the head in C. carpio (such as the
center of the upper lip) is less sensitive (3 orders of magnitude) to
saccharosa than to cysteine.
