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
