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. [1] It is also used as a measure of the growth potential of a site that may be affected by vegetation in the area along with other nearby trees.

All species show some form of parental care for both eggs and larvae, often nurturing free-swimming young until they are weeks or months old. Communal parental care, where multiple monogamous pairs care for a mixed school of young have also been observed in multiple cichlid species, including Amphilophus citrinellus , Etroplus suratensis , and ...
For trout, stocking rates of 30 to 50 kg/m 3 are normal at the end of a rearing cycle, while for marine species, such as sea bass and sea bream, the achievable load is lower, between 15 and 20 kg/m 3. The total volume required for a raceway is calculated by dividing the total amount of fish in kg by the desired stocking rate in kg per m 3. [17]
A stand density management diagram is a simple biological model relating forest yield to forest density at any stage of a particular forest stand's development. [1] Stand density management diagrams are used in forest management and designed to use a current stand's density to project its future yield . [ 2 ]
Tilapia (/ t ɪ ˈ l ɑː p i ə / tih-LAH-pee-ə) is the common name for nearly a hundred species of cichlid fish from the coelotilapine, coptodonine, heterotilapine, oreochromine, pelmatolapiine, and tilapiine tribes (formerly all were "Tilapiini"), with the economically most important species placed in the Coptodonini and Oreochromini.

Stocking densities range from 8 to 18 kg (18 to 40 lb)/m 3 for Atlantic salmon and 5 to 10 kilograms (11 to 22 lb)/m 3 for Chinook salmon. [ 9 ] [ 14 ] In contrast to closed or recirculating systems, the open net cages of salmonid farming lower production costs, but provide no effective barrier to the discharge of wastes, parasites, and disease ...
The redbelly tilapia (Coptodon zillii, syn. Tilapia zillii), also known as the Zille's redbreast tilapia or St. Peter's fish (a name also used for other tilapia in Israel), is a species of fish in the cichlid family. This fish is found widely in fresh and brackish waters in the northern half of Africa and the Middle East.
