Experimental culture of the river prawn Macrobrachium americanum larvae (Bate, 1868), with emphasis on feeding and stocking density effect
In the context of the information found, may affirm that the stocking density effect
over the final weight of the fish may be directly related to growth phase, species, age, size, management and time of year (MATTOS et al., 2013).
 and Huang and Chiu  argued that tilapia is a territorial and aggressive fish so that the density effect
on growth might be explainable by their competition for territories, as well as the permanent stress caused by crowding.
Upon addition of non-predator snails and tadpoles in succession, the density effect
was not significant as observed through the post hoc Tukey tests (Table 2).

as a determining factor of the wing-form in the brown pl anthopper Nilaparvata lugens.
Next, we evaluated the neighborhood aggregation effect, i.e., local density effect
, on the reproductive process.
However, speakers of German showed the same difference between the two sets of pictures as Spanish speakers did in a picture naming task, which suggested that any explanation of neighborhood density effect
may not depend on language-specific properties.
