Aquaponic systems (AS) produce clean food, generate higher yields, consume few resources and are friendly to the environment. In aquaponics, it is important to define the relationship between the stocking density of fish and plants to maintain an appropriate balance among food supply, nutrient production and nutrient assimilation. Therefore, this s...

To date, little attention has been paid to identifying the effects of long-term cryopreservation on sperm quality for Piaractus orinoquensis. The object of this study was therefore to evaluate the effect of long-term cryopreser-vation (24 h, 1, 6 and 12 months) on sperm motility, viability, DNA integrity, ATP content, total antioxidant capacity (TA...

Total ammonia-nitrogen (TAN) excretion from aquaculture systems is determined by several biological and physicochemical parameters, such as sowing density. If TAN is not suitably controlled, food consumption and growth will become reduced, eventually leading to death. The relationship between sowing density and TAN excretion rate must thus be defin...
