The Effcet of Combined Use of Several Alternnative Protein Sources in Fingerling Rainbow Trout Diets
PCR-denaturing gradient gel electrophoresis (DGGE) and canonical correspondence analysis (CCA) were used to explore the relationship between eukaryotic plankton community succession and environmental factors in two aquaculture pond models with gibel carp Carassius auratus gibelio. The main culture species of pond 1 were gibel carp and grass carp, and the combined density was 46224 fingerling/ha...
The aim of this work is to evaluate how changes in a set different key operational factors (e.g., the unit sales price, fingerling cost, feed and so on) would impact on economic performance typical grow-out farm producing European sea bass Mediterranean under scenarios production related size (production volume) strategy (size produced fish). A what-if analysis using deterministic static model ...
To estimate the current significance of area for fish breeding, species composition and abundance young-of-the-year coastal zone Volga-Sviyazhsky Volga stretch Kuibyshev reservoir 2021, 2022 were considered. The work to assess young was carried out at 7 stations, depths less than 2 meters. number calculated per unit effort fingerling seine. Species diversity assessed using Shannon-Weaver index....
A study was conducted to determine the effects of dietary vitamin C on growth performance, feed utilization and carcass biochemical composition of Barbus sharpeyi fingerling. Five diets containing (0, 500, 1000, 1500 and 2000 mg kg-1) of ascorbic acid were fed to benni fingerlings (6.96±0.3 g) in triplicate tanks and twice daily for a period of 56 days. The weight gain significantly increase...
