Stocking Density and Supplemental Feeding
Pond carrying capacity is largely determined by management practices. Earlier work on semiintensive culture of tilapia using manure or inorganic fertilizers indicated that carrying capacity might reach 2,000 to 3,000 kg/ha (Diana et al. 1991a, b; KnudHansen et al. 1991). As stocking density is increased in fertilized ponds, carrying capacity remains largely the same and density-dependent growth...
متن کاملStocking Density Affects Trampling and Use of Vegetation on Nebraska Sandhills Meadow
Ultrahigh stocking density (113,000 kg of beef per ha to as high as 1 million kg per ha) or mob grazing has been suggested to build soil, increase forage production and plant diversity, and improve grazing distribution compared to less intensive grazing systems. Experimental evidence does not completely support such conclusions. The overall focus of this research is based on the approach of bui...
متن کاملCattle grazing a riparian mountain meadow: effects of low and moderate stocking density on nutrition, behavior, diet selection, and plant growth response.
Twelve ruminally cannulated and six intact crossbred beef steers were used in a randomized complete block design to evaluate the effects of stocking density of a riparian pasture in the Sierra Nevada mountains on grazing behavior, dietary selection, forage intake, digesta kinetics, and growth rates of Carex nebraskensis and Juncus balticus. Nine .5-ha pastures were assigned to one of three trea...

متن کاملStocking density at early developmental stages affects growth and sex ratio in the European eel (Anguilla anguilla).
To investigate the effect of stocking density on growth and sex ratio in European eel, four constant density conditions were tested during the transition from the glass to the elver stage for 90 days (Period 1). The test conditions combined the weight of fish per unit surface or volume (surface density or volume density) resulting in four experimental groups: low surface density (0.5 kg/m(2)) a...
