Effects of Different Dietary Protein Levels on the Growth Performance, Physicochemical Indexes, Quality, and Molecular Expression of Yellow River Carp (Cyprinus carpio haematopterus)

“…The relatively low WG and SGR obtained in the present study were compared with the findings of published papers [ 14 ], which illustrated that there are some differences in growth performance between different carp varieties. In comparison with the same carp varieties [ 9 , 12 ], the IBM of large-sized Cyprinus carpio haematopterus was selected and found to affect the SGR and WG in the present study. The WG and SGR were first significantly enhanced with the increase in the dietary protein up to an optimal level, while thereafter, they slightly decreased, which illustrated that excessive dietary protein levels affect the nutrient utilization and feed efficiency [ 3 ], further resulting in the clear growth inhibition of fish [ 14 ].…”

“…The culture pattern includes ponds, reservoirs, lakes, and rice fields. Yellow River Carp ( Cyprinus carpio haematopterus ) is a major commercial farmed species belonging to Cyprinus carpio , which has been cultivated widely, especially in Northern China, because of its delicious flesh, high disease resistance, and elegant appearance, with golden scales and red or orange tail fins [ 9 ]. As previous studies have mentioned, the dietary protein levels decrease with the increase in the fish body size [ 10 ].…”

“…As previous studies have mentioned, the dietary protein levels decrease with the increase in the fish body size [ 10 ]. Previous studies on the dietary protein levels of Cyprinus carpio mainly focused on juvenile Cyprinus carpio with weights below 20 g [ 9 , 11 ] and juvenile Cyprinus carpio haematopterus with weights of 21.56 ± 0.46 g [ 12 ]. Song et al [ 9 ] demonstrated that appropriate dietary hydroxyproline supplementation can promote myogenesis and collagen synthesis in the muscle of Cyprinus carpio haematopterus , and this ultimately improves the raw- and cooked-fillet texture characteristics.…”

Yun et al [ 12 ] posited that different dietary methionine supplementations can affect the growth performance and fillet texture characteristics of Cyprinus carpio haematopterus .…”

Muscle Nutritive Metabolism Changes after Dietary Fishmeal Replaced by Cottonseed Meal in Golden Pompano (Trachinotus ovatus)

“…Previous studies demonstrated that alternative proteins replace fishmeal (FM) disturbed muscle nutrient metabolism and further resulted in the muscle growth restriction considered as an important limiting factor affecting substitution efficiency [ 3 , 4 ]. Additionally, the main goal of the aquaculture was to improve feed utilization, which in turn efficiently promoted muscle deposition [ 5 , 6 , 7 ]. Therefore, muscle nutrient deposition was the important indicator to assess the efficiency of alternative protein sources in substituting FM.…”
