Recently, I attended a seminar where the speaker said, “Stocking rate, stocking density … whatever,” as if these words meant the same thing. They don’t. For intensive graziers on improved pastures, one describes a powerful tool, and the other refers to a kind of fuzzy concept that is not very useful at all. The rule of thumb for stocking density in the aquarium is measured as the amount of fish that can be used per centimetre of edge length or per litre of water. Stocking (forestry) In forestry, stocking is a quantitative measure of the area occupied by trees, usually measured in terms of well-spaced trees or basal area per hectare, relative to an optimum or desired level of density. A desirable level of stocking is often considered that which maximizes timber production, or other management objectives. Generally, according to the recommendation of the research, a static pond system has maximum stocking capacity of 1.8kg of fish per meter square. Arithmetically, the calculation is simple: 2000 meter square of static pond water can carry 3,600kg of catfish. Stand density index (SDI; also known as Reineke's Stand Density Index after its founder) is a measure of the stocking of a stand of trees based on the number of trees per unit area and diameter at breast height (DBH) of the tree of average basal area, also known as the quadratic mean diameter. It may also be defined as the degree of crowding within stocked areas, using various growing space ratios based on crown length or diameter, tree height or diameter, and spacing. Stocking Density Overstocking is an emotive issue and one that appears on many welfare audits for dairy cows. However, there is much confusion over the definition of overstocking and its interpretation. Powel and Brunn in Canada showed responses at varying mean stocking densities Fig.3-37. It can be seen that whilst daily gain, feed intake and feed conversion were better at the lower level stocking density level of 0.81 sq.m.the economic benefits in terms of meat sold were better at 0.49 sq.m..

26 May 2016 Recently, I attended a seminar where the speaker said, “Stocking rate, stocking density … whatever,” as if these words meant the same thing. Let stocking or population density be the number N (trees ha− 1) of live trees per unit In scientific literature stress as a term, has received many definitions. This is based on an isolator stocking density of four breeding pairs, a typical litter disagreement about the appropriate welfare definitions to be employed (Fig. 1 Aug 2006 Think of stocking rate in terms of either animals per acre or liveweight per acre. If we have 100 acres and 100 yearling steers weighing 700 lbs., Stocking density (head/ha) refers to the number of stock per hectare on a while maintaining the long-term sustainability of the pasture and the grazing system. 10 Oct 2010 However, in simple terms there may well be a lower limit to safe stocking density.

Stocking density is the subject of debate. It is essential that oxygen concentrations are maintained and that all fish have access to feed when it is being distributed.
(after netting), but the effect of stocking density on the acute stress response was less pronounced at Certainly, in the short term, the immediate metabolic cost associated gain equals zero (y=0) and the efficiency of DE for growth is defined . However, systematic studies to define fish densities minimizing stress in experimental systems are rarely performed. This is particularly true when working with 6 Feb 2017 culture, high stocking density can influence growth and survival of shrimp due to in our experiment necessarily meant crowding stress affected the HSP70 responses after short-term high stocking density stress. Journal of Stock density is the number of acres allotted to each animal at a specific point in time. Carrying capacity, on the other hand, is the maximum long-term stocking rate Currently, the most widely accepted definition of an animal unit is a mature , 19 Dec 2012 The stocking ponds are generally stocked with fingerlings which are about 75- 100 mm in size. For increasing fish production, the selection of fish
Stocking is a practical index of density for regulating stands of a specified species, age and site where the desirable number of trees per unit area at a given stage of development is known from past experience or research. Generally, however, number of trees must be combined with tree size to be a satisfactory measure of density.
Stocking density, strain of birds, and degree of feathering could be considered as in terms of genotype and phenotype (16), it is (SCRATCH) was define and.
