Objectives:

Th e relevant factors in aquaculture production are the physical and chemical parameters of water, such as temperature and oxygen, among others, which directly infl uence the biochemical and physiological processes of plants and animals.

Results:

Th e imbalance of the dissolved oxygen, usually derives from an inadequate water body management, a defi cient calculation of the fi sh biomass, excess of organic matter, and contamination, causing up to 60% of the losses in a crop.

Conclusions:

The aim is to briefl y collect and emphasize on some basic concepts of water quality, alternatives in pond infrastructure, a suggested fi sh biomass, and the use of common forage plants of the Andean zone for sustainable peasant fi sh farming.
