Correlated basal expression of immediate early gene egr1 and tyrosine hydroxylase in zebrafish brain and downregulation in olfactory bulb after transitory olfactory deprivation

“…Imprinting on kin versus non-kin has recently been shown to occur in zebrafish during a 24 h time window at day six of larval development and to depend on olfactory cues (Gerlach et al, 2008;Mann et al, 2003). During larval life, this allows formation of shoals based on kin association (Gerlach et al, 2007).…”

The importance of the lateral line in nocturnal predation of piscivorous catfish

“…Fish are known to have extraordinarily sensitive chemical senses enabling them to distinguish between different species and even individuals (Brown and Smith, 1994;Kleerekoper, 1969;Mann et al, 2003). Olfaction in fish is located exclusively in the nose, while gustation is perceived inside the mouth and, in some fish, also on parts of the body surface.…”

Humic Acid Interferes with Species Recognition in Zebrafish (Danio rerio)

“…1) powered by a peristaltic pump. The flume allows a laminar flow separation of two water stimuli (Atema et al 2002;Mann et al 2003;Gerlach and Lysiak 2006). The water height was maintained at approximately 1.5 cm, and uniform unidirectional flow was maintained at a constant rate of 106 ml/min or 6.2 cm/s).…”

“…Additionally, from 1980 to 2000, use of synthetic nitrogen fertilizers in East Asian riceproducing nations has increased from approximately 4 to 10 Tg [Food and Agricultural Organization (FAO) 2002] as part of a transition from more traditional to industrialized, broad-scale rice production. As zebrafish use chemical communication in the context of reproductive suppression and stimulation (Van den Hurk et al 1987;Delaney et al 2002;Gerlach 2006) and kin recognition (Mann et al 2003;Gerlach and Lysiak 2006), the chemical environment is likely to affect transmission and reception of chemical stimuli. In this study, we investigated the ability of adult D. rerio to discriminate between conspecific and heterospecific chemical cues in the presence and absence of HA, as well as their habitat preferences for water with and without HA.…”
