Carbon, nitrogen and phosphorus budgets of silver carp Hypophthalmichthys molitrix with the co‑culture of grass carp Ctenopharyngodon idella

Fish farming activities have resulted in increasing nutrient pollution and subsequent deterioration of water quality in aquatic environments worldwide. Silver carp Hypophthalmichthys molitrix can efficiently remove excessive nutrient pollution by filtering the suspended particulate organic matter. T...
