Chemosensory sensitivity of some cyprinid fish to natural attractants
Species
Thresholds of chemosensory sensitivity:
given in parts of standard exctract 1 gram food per l water
(1 gram live food per hour per l water, for exometabolites)
common carp, Cyprinus carpio
10-4 (10-1 g/h/l)
silver crucian, Carassius auratus gibelio
10-3
minnow, Phoxinus phoxinus
10-3 (10-1 g/h/l)
common gudgeon, Gobio gobio
10-3
zebrafish, Danio rerio
10-3
lacustrine bleak, Leucaspius delineatus
10-1
Extracts and exometabolites of bloodworms, Chironomus plumosus, are used in these experiments.
Common minnow, Phoxinus phoxinus
