Apparent availabilities of amino acids and minerals from white fish meal (FM), defatted soybean meal (SBM), malt protein flour (MPF), and corn gluten meal (CGM) were determined for fingerling rainbow trout Oncorhynchus mykiss. Groups of forty fish (mean weight; 13 g) were each allotted to one of six round tanks for collecting feces. A test diet containing one of the protein sources at approximately 35% crude protein level was fed to duplicate groups at 15°C, and the feces were collected. Availability was determined by an indirect method using chromic oxide.<br> Apparent protein digestibility of CGM was the highest (96%), with FM and SBM being slightly lower (94%), and the lowest was MPF (86%). Apparent availabilities of individual amino acids within each protein source were similar and almost approximated to the protein digestibility value. Apparent availabilities of phosphorus from FM and MPF per se were higher than those from SBM and CGM. The copper and zinc availabilities for SBM showed the highest values.<br> These results suggest that the apparent protein digestibility value is indicative of the amino acid availability from a protein source with a high protein digestibility such as FM, SBM, and CGM in fingerling rainbow trout. On the contrary, individual mineral availability values should be assessed to formulate efficient and economical fish feeds.
