Corneal hypertrophy was observed in fingerlings of chocolate mahseer, Neolissochilus hexagonolepis (McClelland, 1839) from Uttarakhand, India. The advanced stage of infection was marked with damage of cornea and shrunken eye. Skeletal deformity was also recorded in some of the infected fishes. Samples of eye and other organ were collected for histopathological, parasite and microbial investigation. Histological examination of the eye indicated ocular collapse, entirely damaged cornea, disruption of vitreous, aphakic globe, oedema of choroid and optic nerve and, deformed retina. Microscopic observations of wet mounts and histopathology ruled out infectious agents like microsporidia, myxosporidea, cystercoidiasis, atypical mycobacteria, digeneans and fungi. PCR for viral aetiology did not yield any significant amplicons. Further detail study related to physic-chemical parameter need to be carried out to ascertain the exact cause of this disease.Keywords

A detailed analysis of depositional history of Miocene sediments and various effects which are governed for creation of accommodation space as well as the processes of sedimentation inherent to the depositional system at that period is described in this work. The early Miocene clastic sediments are deposited in prograding environment where sediment supply exceeds the accommodation space available. The accommodation space created due to basin subsidence and source area upliftment due to local and regional tectonic activity in the basin. In the early Miocene time, the Assam shelf major transgression occurred and several minor transgression followed. There was wide spread deposition of the fluvial Tipam sandstones. In Miocene time due to thrust loading and flexure subsidence, accommodation space was created for deposition of the sediments. The Tipam Sandstone is deposited by cyclic deposition of fining upward sequence in a fluvial to brackish water environment of braided river processes. The mechanism of braided rivers is also discussed in which it laterally expanded, leaving sheet like or wedge - shaped deposits of channel and bar complexes preserving only minor amounts of flood plain material.Keywords
