The identity and generic placement of Barbus mussullah Sykes, the type species of Hypselobarbus Bleeker, have for long been unclear, variously having been considered a synonym of Cyprinus curmuca Hamilton or a species of Tor Gray or Gonoproktopterus Bleeker. Here, through a re-examination of the original descriptions and the examination of specimens from western peninsular India, we redescribe ...

The suitability of three anatomical structures to determine age and growth of bull trout, Salvelinus confluentus (Suckley), was assessed. Scales and pelvic fin rays collected from recaptured bull trout 96–265 mm TL were used to validate annulus formation and assess the accuracy and precision of back calculation. Ageing precision and agreement of assigned ages were compared among scales, fin ray...

The world is looking towards producing products which consume less power without compromising on quality of life. The increase in use of refrigeration and air conditioning appliances are contributing to global warming. The world wide temperatures are shooting up at an increasing rate. This paper presents a design of roll bond evaporator as the heat exchanger to provide cooling in room air condi...

A new species of nemacheilid, Physoschistura dikrongensis, is described from the Brahmaputra basin in Arunachal Pradesh, India. It is easily distinguishable from congeners in having two V-shaped dark brown bars across the caudal fin towards the distal end; 11–15 irregular bars on the body; dark brown mottled markings on the head; 4 simple and 81⁄2 branched dorsal-fin rays; 4 simple anal-fin ray...

Increased interest in using zebrafish as a model organism has led to a resurgence of fin regeneration studies. This has allowed for the identification of a large number of gene families, including signaling molecules and transcription factors, which are expressed during regeneration. However, in cases where no specific inhibitor is available for the gene product of interest, determination of a ...

Two new species of the gobiid genus Cabillus, C. nigromarginatus sp. nov. and Cabillus nigrostigmus sp. nov. are described. Cabillus nigromarginatus (from Rodrigues, Western Indian Ocean) is distinguished from congeners by having 18-20 pectoral-fin rays; predorsal area naked; two scales with enlarged ctenii ventrally and dorsally at the caudal-fin base; head with anterior and posterior oculosca...
