Comparative transcriptome profiles of large and small bodied large-scale loaches cultivated in paddy fields
Abstract Fish culture in paddy fields is a traditional aquaculture mode, which has a long history in East Asia. Large-scale loach (Paramisgurnus dabryanus) fast growth is suitable for paddy fields aquaculture in China. The objective of this study was to identify differential expression genes (DEGs)...
