An experiment on rearing of common carp was carried out in three types of ponds viz. earthen pond, cemented tank and poly tank at field centre, DCFR, Champawat (Uttarakhand) and at selected farmers field of Champawat District to evaluate the growth performance of this fish species. ANCOVA results revealed that there are three distinct seasons which influence on length-weight relationship of common carp culture in these pond systems. The fish follows isometric growth in spring season (March-May); (however it does not follow in the remaining seasons). Further, there is no specific growth pattern of common carp observed in these pond environment. Logistic curve is the best fitted model to the dataset obtained from cemented pond. However, Richards and von-Bertalanffy curves are found appropriate to represent the growth pattern of this fish in earthen and poly tank, respectively. In the long run, higher growth of fish is predicted in poly tank.Keywords

Continuous measurements of surface-level carbon dioxide (CO2) along with its co-emitted carbon monoxide (CO) and methane (CH4) are being made at Ahmedabad using a laser-based cavity ring down spectrometer, which offers much longer path length for accurate and fast measurements of these species simultaneously. The average data during November 2013 show large variability in all the three species. These measurements also show significant diurnal variations with maximum in CO being relatively the shortest-lived species in this set of gases. The correlations and slopes among them have been used to identify potential emission sources.Keywords
