Bighead and silver carp were considered the most significant threat because of their overconsumption of plankton.
Maybe because carp are considered to be not very beautiful fish that inhabit not very beautiful places.
Dactylogyrus parasitizing Carassius species and closely related common carp are considered to be the most pathogenic monogenean species on the gills causing fish mortality [ 33, 34].
In common carp and ornamental koi (Cyprinus carpio), Cyprinid herpesvirus 3 (CyHV–3, KHV), is considered as major viral pathogen.
The similarity searches against 4 model fish species reference genomes showed that 59.2% grass carp sequences used were considered to be significantly similar to zebrafish genome sequences.
Imported in the 1970s to control algae growth in aquaculture and wastewater treatment facilities, the carp soon escaped and are considered highly invasive species.
In addition to its aquaculture importance, common carp is also considered as a model species for studies on ecology [ 2], environmental toxicology [ 3, 4], development [ 5], immunology [ 6], evolutionary genomics [ 7], nutrition [ 8], and physiology [ 3].
In this model, two types of phytoplankton (non blue-green algae and blue-green algae), three types of zooplankton (rotatoria, cladocera and copepoda), planktivorous fish (crucian carp), detritus and dissolved matters were considered.
ZE-type have since been found in several teleosts [ 29, 34, 35], while the sequences described by Okamura et al. [ 32] are considered unique to carps.
KEGG pathways with corrected p values ≤ 0.05 were considered to be statistically enriched in common carp.
