Copépodos parásitos (Siphonostomatoida: Pandaridae) de Prionace glauca e Isurus oxyrinchus, capturados en la costa central de Chile

In the Chilean coast, sharks and rays are one of the least studied fish groups, therefore quantitative data about theirparasites are scarce or almost non existing. Copepod parasites were collected from different sites along corporal body of Prionace glauca (n= 12) and of Isurus oxyrinchus (n= 1) captured onboard cruise OCEARCH during March and April 2014. Three species belonging to the Pandaridae family were identified: Echthrogaleus coleoptratus, Dinemoura producta and Nessipus orientalis. The latter species is here recorded for the first time in Chilean waters. These copepods did not show infection site preferences along host body. Considering the wide range of hosts described for these parasite species, it is concluded they are generalist parasites of wide geographic distribution.

Copepod parasites of marine fishes Gazza achlamys (Jordan & Starks, 1917) and Ariomma indica (Day, 1871) from Visakhapatnam coast, Andhra Pradesh, India.

A survey has been conducted to collect copepod parasites from Gazza achlamys (Jordan & Starks, 1917) and Ariomma indica (Day, 1871) off Visakhapatnam coast. Altogether, seven copepod species were identified. They are Caligus kuroshino (Shiino, 1960), Bomolochus decapteri (Yamaguti, 1936), Bomolochus nothrus (Wilson, 1913), Pseudartacolax lateolabracis (Yamaguti et al., 1959), Pumiliopes opisthopteri (Shen, 1957), Lernanthropus amphitergum (Pearse, 1951) and Lernanthropus ilishae (Chin, 1948). A list of hosts parasites and brief description of these parasites has given in this paper.

A study on copepod parasites of marine fish Johnius aneus (Bloch, 1793) from Visakhapatnam coast, Andhra Pradesh, India.

Dumping of industrial wastes into the sea is a common factor in and near by coastal cities where by there are mass mortalities of fishes as well as health deterioration of fish health. These fishes are prone to secondary infections by microbial and eukaryotic parasitic species. In the present study a survey has been made on Johnius aneus for copepod parasites infection. The study has been conducted+ for 10 months. 3 species of parasites were recorded-Lernanthropus Otolith, Pillai, 1963 Caligus annualaris Yamaguti, 1954 and Brachiella albida Ranganekar, 1956. To know the host parasite interaction, prevalence and Mean Intensity of overall parasites and individual parasite species have been studied. It is found that over all prevalence is high being 44%, whereas Mean intensity is less being 1.6. This gives an overall view of parasitization of copepods on the fish Johnius. It indicates that infection with copepod parasites is common but not heavy.

Lernaea (Anchorworm) Infestations in Fish

Lernaea species, commonly known as “anchorworms,” are crustacean, copepod parasites that can infect and cause disease and mortality in many types of freshwater fishes, especially wild-caught and pond-raised species. Infestations with Lernaea are most prevalent in the summer months and occur more commonly in stagnant or slow-moving water bodies. This 4-page fact sheet was written by Natalie Steckler and Roy P. E.
