Dear Respected Researcher Rajeeb K. Mohanty,
We know various biological processes in aquaculture systems has direct impact on health and quality of fish. Feeding behavior, tropic structure,pelagic (littoral, limnetic, pro-fundal zone of a water area) etc. If you use high stocking density therefore fishes are certainly compete for the food which certainly affect their homeostasis. Moreover, various inter and intra specific interaction regarding feeding behavior existed.
High stocking density often responsible for the deterioration of the water quality (eg. pH, DO, NH3, NO2 etc) and excess excreta often causes toxic gas in the sediments that often responsible for decrease appetite, fouling or even fish mortality.
You may find a lot of published articles concerning the feeding behavior, feeding regime and stocking density of culture fish. I have some collection of them. If you require, then let me know.
Dear Mohanty,
I think Mohammad Hossain and Sana Ullah answered very well to your question. Density can affect feeding behaviour o fish both for density itself and products of feed stuff decomposition.
Dear respected Emiko K. Resende,
I think your answer is certainly in line with the query. Sincere thanks to you for VOTING & giving your opinion in favor of our answers.
Dear Researcher
In carp aquaculture higher stocking density is not suitable in general for success of your project. It is the one factor which has significant effect on fish growth. The pond ecosystem will be disturbed and fish will become under stress. The biology of under stress fish is never normal. The answer by others experts seems fine.

Dr. Mohanty,
You have asked about stocking density and feeding behavior ? If stocking density is below prescribed system density then competition will be less and uniform growth may be observed. But with high stocking density some will grow more faster than others because of dominant effect for feed obtaining. It also depend on species, some shows much vigor in feed competition than other species. However, it is all relative and species specific.
In general, high stocking densities can induce stress on fish and deteriorate the water quality, that will inhibit fish feeding. However, it depend on species and the culture system that you you are using. The performance of an fish species is distinct in a pond comparing to an RAS for example.

I agree with above. There are many published articles about the feeding behaviour, feeding regime and stocking density of culture fish. S0, you may go to: https://www.researchgate.net/post/How_does_density_affect_the_feeding_behavior_of_fish
El efecto de la densidad depende de si el pez es gregario o no , depende de la estructura de dominancia en el grupo, en muchos Piaractus la tendencia de animales grandes es defender un determinado espacio cuando están en bajas densidades (menos de dos animales metro) pero a mayor densidad no manifiestan dicha territorialidad.
