Experiment was conducted in 0.0-ha earthen ponds to promote growth performance of silver carp and Cyprinus carpio big head (cyprinid) plus phytoplankton zooplankton were estimated a pond receiving mixed fertilizer with vermicomposting, 6000 12000 kg per/ha/year (VC6 VC12) 6000, without vermicomposting (CO6and CO12). All treatments compared finally. Significant differences found diversity abunda...
We describe herein a useful model for assessing the environmental impact of the breakage of earthen dams used to retain leachate fluids. To create this model, we analyzed three parameters: (1) the characteristics of both the earthen dam and the leachate; (2) the behavior of the leachate cascade resulting from breakage of the dam; and (3) the environmental effect of the resulting pollution. To a...
in order to determine of some blood serum biochemical parameters in rainbow trout, blood samples were taken from the caudal vein of 531 apparently healthy rainbow trout cultured in earthen ponds. data was analyzes by regression analysis, pearson correlation coefficient test and fisher's test. the mean values of alp, ast, alt and ldh were 722±320, 337±150, 29±24 and 579±353 u/l and the mean...
Effect of aeration on growth and production of fish in intensive aquaculture system in earthen ponds
420 Introduction Going back to the starting point of the development, the following question arises: What are the desirable parameters of stabilized outdoor earthen plaster? To be able to reply to this question, we must first define onto what surfaces the plaster will be applied. Modern earthen structures built in our climatic zone must be fitted with thermal insulation and treated as compositi...
