The classic literature with methods for determining the digestibility of fish? It is mainly written by cho.

The first article is Cho, C.Y., Slinger, S.J., Bayley, H.S., 1982. Bioenergetics of salmonid fishes: energy intake, expenditure and productivity. Comp. Biochem. Physiol. 73B, 25Mutual 41. The second is Cho C Y, Slinger S J. Apparent digestibility measurement in feedstuff for rainbow trout [J]. Finfish Nutrition and Finfish Technology,1979, 2VO239. These are all the most classic works on the determination of digestibility. If the prawn has an electronic full text, can you share it? thank you! -- what an early article. I guess it's hard to find an electronic version, right? It is suggested to check it in the library. Hehe-- Yes, it's not convenient for me to go to the library, so it's best for me to ask for help.
