Dolops

Dolops is a genus of parasitic copepods belonging to the family Dolicopidae. These marine ectoparasites primarily infest fish hosts, attaching themselves externally to the skin, fins, or gills. The genus Dolops is characterized by a flattened, elongated body and specialized mouthparts adapted for feeding on host tissues and blood.

Members of Dolops are found in various marine environments, often associated with freshwater and estuarine fish species in regions such as South America, Africa, and Southeast Asia. The life cycle of Dolops involves a series of developmental stages, including nauplius and copepodid stages, culminating in adult parasitic forms.

Dolops species can impact their hosts by causing lesions, irritation, and sometimes secondary infections. They are also of interest in the study of parasite-host interactions and fish health management, particularly in aquaculture settings where infestations can affect fish welfare and commercial productivity.

Taxonomically, Dolops includes several species, with the genus distinguished by morphological features such as body segmentation and appendage structure. Ongoing research continues to expand understanding of their ecology, life cycle, and evolutionary relationships within copepods.

Overall, Dolops serves as an example of marine parasitism with significant implications for ecological studies and fishery management, highlighting the importance of monitoring parasitic copepods in aquatic ecosystems.
