effects of different amounts of morning liming on blood ionic parameters and blood biochemical parameters of cultured carp ponds in dikjeh area of gonbad were investigated. 9 ponds (3 hectars) were chosen and divided in 3 treatments (1- liming 750 mg/l, 2- liming 1250 mg/l, 3- liming 1750 mg/l). liming had significant effect on blood hematocrite (p0.05) were observed between other blood paramet...

A pond heat and temperature regulation (PHATR) model was designed to: (1) predict the temperature for earthen outdoor aquaculture ponds and (2) determine the size of energy transfer mechanisms affecting energy gains or losses for these ponds. The model solves a first order, no-linear differential equation using a 4th order Runge-Kutta numerical method and various input data (weather data, pond ...

BACKGROUND Traditional rural landscapes of Eastern Europe are undergoing major changes due to agricultural intensification, land abandonment, change in agricultural practices and infrastructural development. Small man-made ponds are important yet vulnerable components of rural landscapes. Despite their important role for biodiversity, these ponds tend to be excluded from conservation strategies...

The objective of this project is to compare growth and survival rate in Chinese carps reared under traditional culture conditions versus those reared in ponds treated with slurry (anaerobic fermented of cow manure). This experiment was conducted using two treatments one treatment using slurry and the other using cow manure plus chemical fertilizer as the control with three replicates for each....

purpose: the aim and objective of this report is to identify the benefits of interactive communication channels and to advice the fmcg business on how these new methods are better than the conventional methods. design/ methodology/approach:  in this research article facts about advertisement and its effectiveness were collected from different surveys conducted by various agencies. mainly second...

Conservation of endangered, cold-stenothermic species, such as the freshwater pearl mussel (FPM) and its salmonid host fish, are particularly challenging in headwater streams their last refuge areas. Understanding impact anthropogenic catchment features fish ponds on hydrology temperature regime is, therefore, important. In this study, runoff a FPM with more than 150 small was simulated using S...

An increasing focus of interest in ponds over the last two decades arose largely because of concerns at the loss of ponds in intensively developed landscapes. In the UK pond numbers declined from approximately 800,000 in the nineteenth century to 200,000 by the 1980s. Since then pond numbers have started to increase. The focus on overall pond numbers overlooks the importance of the history and ...
