چکیده

the cellular organization of the olfactory epithelium of puntius sarana (hamilton, 1822) was explored by means of optical and scanning electron microscopy. the oval shaped olfactory rosette was composed of 26-28 primary lamellae distributed from both sides of the central raphe. the sensory epithelium confined chiefly on the linguiform processes of the lamella and rest of the portion consisted of non-sensory epithelium. the sensory epithelium was embossed with morphologically distinct three types of sensory cells: ciliated, rod and microvillus receptor cells. the non-sensory epithelium was made up of mainly stratified epithelial cells and mucous cells. different cells lining the olfactory epithelium were discussed in relation to mode of life and living of the fish concerned.

Differential C-heterochromatin distribution in two species of freshwater fish, Anabas testudineus (Bloch.) and Puntius sarana (Hamilton.).

Anabas testudineus (2n = 46) had the more conserved pattern of its C-heterochromatin distributed mainly in the centromeric region, whereas Puntius sarana (2n = 50) exhibited a rather unorthodox pattern, many chromosomes showing interstitial, some telomeric and a few chromosomes showing centromeric C-band localization. Further, lateral asymmetry in distribution of heterochromatin was also noted ...

When presented with stimulus shoals of siblings and conspecifics in equal number, P. sarana subnasutus were able to discriminate their siblings and preferred to associate with them. Given a choice between large shoal and a small shoal consisting of siblings, the juvenile fish preferred to associate with larger stimulus group to the smaller one. However, juveniles traded off their preference for...
