An experiment on the polyculture of carps with high valued small indigenous fish species (SIS) pabda (Ompok pabda) and gulsha (Mystus cavasius) was carried out in six months culture period to evaluate the production performance of carp with small indigenous fish pabda (Ompok pabda) and gulsha (Mystus cavasius) in the on-farm condition. Three stocking densities of pabda and gulsha were tested, k...

To examine the long term e ects of fertiliser application on pasture growth under grazing a mathematical representation of the pasture ecosystem is created and analysed mathe matically From this the nutrient application level needed to maintain a given stocking rate can be determined along with its pro tability Feasible stocking levels and fertiliser application rates are investigated and the o...

INTRODUCTION Vegetation and livestock responses from a 25 year (1982-2006) grazing system and stocking rate study in the northern mixed-grass prairie at the USDA-Agricultural Research Service, High Plains Grasslands Research Station near Cheyenne, Wyoming are presented here. This study was longest known grazing system X stocking rate study in North America and was one of the few studies to use ...

To evaluate effects of stocking density on welfare of Amur sturgeon (Acipenser schrenckii), an experiment was designed using three initial stocking densities in flow-through tanks (LSD = 3.7 kg m , MSD = 6.9 kg m , and HSD = 9.3 kg m , respectively) for 60 days. Growth, body composition, and haematological and biochemical parameters were monitored. The mortality and feed conversion rate (FCR) w...

in order to estimate responses of growth rate and growth hormone of clarias gariepinus to stocking density, fish (initial weight 30.71 ± 0.89 g) were stocked in 120-l tanks at densities of 35, 65, 95, and 125 kg/m3 for 60 days. on day 30 and 60, the fish growth rates were measured, pituitary growth hormone (gh) mrna levels and serum gh concentrations were examined by real-time qpcr and elisa te...

To observe the effectiveness of short time in-pond nursery of post larvae (PL) on the survival rate and production of shrimp (Penaeus monodon) under modified improved culture system, an experiment was conducted in earthen ponds at Brackishwater Station of Bangladesh Fisheries Research Institute, Khulna. Results of the experiment revealed that short time in-pond nursery of PL provided the signif...

Stocking density is considered one of the important factors affecting fish growth. But, information related to impact of stocking density on growth performance of monosex tilapia population under the ecological conditions of Gangetic plains in West Bengal, India is limited. The aim of our study was to compare the growth potential of monosex tilapia at various stocking densities and to determine...

To compare the performance of steer calves managed under different stocking rates (SR; 3.7, 6.2, 8.6, and 11.1 steers/ha for 140 d; chi(I1)) and N fertilization rates (112, 224, and 336 kg of N/ha; chi(I2)) in May 1996, 1997, and 1998, 72 steer calves (BW = 231 +/- 2.5 kg) were assigned randomly to one of 12 0.81-ha dallisgrass (51%)/common bermudagrass (32%) pastures. One-third of the fertiliz...
