INTRODUCTION
Olfaction is an important type of chemoreception
which is mediated through well developed, complex and
organized olfactory system in vertebrates (Freitag et al.,
1999). This system generally develops from the
specialized tissue, called olfactory placode (von Kupffer,
1894). In the early stage of development, placodes are
formed from the preplacodal ectoderm of the anterior
region of the embryo, medial to epidermis and lateral to
both neural crest and neural plate (Knouff, 1935).
The developmental process leading to the formation of
fish olfactory organ, is little diverse (Hansen and
Zielinski, 2005). The peripheral olfactory organ is the
first chemosensory organ to develop in fish preceding the
systems of solitary chemosensory cells (Kotrschal et al.,
1997) and taste (Hansen et al., 2003). Fish generally
possesses a paired olfactory organ located at the anterior
part of the head (Derivot, 1984; Hansen and Zeiske,
1998; Døving, 2003; De and Sarkar, 2009). The olfactory
