Webphysicochemical variables in fish farming such as dissolved oxygen, tem perature and pH in a tilapia culture. This in order to optimize the living conditions of this fish species and … WebThe parameters of temperature, pH, and dissolved oxygen for all treatments were obtained values corresponding to the life of tilapia. Temperature parameters ranged from 25.80 to 29.27 C (Figure 1), while the pH ranged from 7.21 to 7.77 (Figure 2), and for dissolved oxygen, it ranged from 6.60 to 10.50 mg/L (Figure 3).

WebMinimum dissolved oxygen requirements of freshwater fish. Coldwater fish like trout and salmon are most affected by low dissolved oxygen levels 19. The mean DO level for adult salmonids is 6.5 mg/L, and the … WebDissolved oxygen Adequate dissolved oxygen is criti-cal in hatcheries because eggs and fry have high metabolic rates and thus a high requirement for oxy-gen. Dissolved oxygen concentra-tions should not fall below 4-5 ppm at any time within the hatch-ery. Proper management of dis-solved oxygen involves two distinct considerations: (1) ensur- WebNile tilapia need water with a dissolved oxygen content above three parts per million (ppm) and Blue tilapia need their oxygen above seven ppm.
