FECO : In order to uniformly mark the experimental background of fish omics in FishCODE, based on the Zebrafish Experimental Condition Ontology (ZECO), we comprehensively consider the experimental background of the previously collected fish omics data, fish ontology (FISHO), biological attribute ontology (OBA), Ontology of Experimental Conditions (EFO) and Ontology of Livestock Animal Traits (ATOL) form a preliminary vocabulary for an ontology of experimental conditions for fish based on omics data. Compared with ZECO (161), this ontology vocabulary has added 31% of the entries (211). Download the vocabulary and structural relationship files for FECO download

Overview of newly added vocabulary : The new vocabulary and adjusted structures are mainly in three categories. The first category is also the most common category, which is a data set based on the attributes of the fish itself as experimental conditions, such as diseases (tumors, scoliosis), special strains (easy / Resistant and susceptible strains, subspecies with different living environments, subspecies hybrids), behavior (swimming ability, migration, reproduction), phenotype (body color, body size), etc. The second category is genetic manipulation. Researchers who study genetic mechanisms often perform genetic manipulations, such as transgenesis, gene knockout, gene overexpression, gene knockdown, etc. The third category is based on farming (source and composition of feed ingredients, feeding environment, feeding habits, etc.). Considering that the omics data set we collected is not limited to model species but also includes fish such as Atlantic salmon, rainbow trout, grass carp, etc. The related omics data of these economic fishes involve more abundant experimental conditions related to breeding.
