Interpretive Summary:

Technical Abstract: White bass (Morone chrysops) are a popular sport fish throughout the southern United States, and one parent of the commercially successful hybrid striped bass (M. chrysops x M. saxatilis). Currently, white bass are cultured using diets formulated for other carnivorous fish, such as largemouth bass (Micropterus salmoides) or hybrid striped bass and contain a significant percentage of marine fish meal. Since there are no studies regarding the utilization of alternative proteins in this species, we evaluated global gene expression of white bass fed diets in which fish meal was partially or totally replaced by various combinations of soybean meal, poultry by-product meal, canola meal, soy protein concentrate, wheat gluten, or a commercial protein blend (Pro-Cision). Significant differentially expressed genes and gene ontology of pairwise comparisons between control diet and each test diet are presented and discussed. Raw sequencing reads and processed gene expression data has been submitted to the National Center for Biotechnology Information (NCBI) Gene Expression Omnibus (GEO) and is available to the public under the accession number GSE220235.
