Some notes on Parasitic and other Diseases of Fish

Abstract

In the following notes no attempt has been made to enter into the pathology or etiology of the diseases described, as only isolated cases have been available for investigation.I am much indebted to the Council of the Marine Biological Association of the United Kingdom for their kindness in granting me a table at their Plymouth Laboratory.

Aquatic fungi growing on eel fry montée Anguilla anguilla L.

“…The first scientist to report on the occurrence of Saprolegnia ferax on European eel larvas was Schnetzler in the previous century (1887). His finding was confirmed later also in adult individuals (Drew 1909;Agersborg,1933).…”

“…The presence of this fungus on adult eel individuals . was confirmed by Drew (1909) and Agersborg (1933). Saprolegnia parasitica was f ound on Anguilla chrysypa Rafinesque by Tifthey (1939a, b), and onAnguillajaponica by Hoshina et al (1960).…”

Microsporidia in Vertebrates: Host-Parasite Relations at the Organismal Level

“…Such infections are similar to those caused by P. myotrophiea and P. danilewskyi in the muscles of amphibians and reptiles. Glugea shiplei Drew, 1910, in Trisopterus luseus (Gadus luseus) may be an exception. Drew (1910) described opaque white cysts of G. shiplei, up to 5 x 3 mrn, surrounded by a thin transparent membrane.…”

Zoosporic fungi growing on the dead glass eel (montée) and elver′s (Anguilla anguilla L.)

“…In the last century Schnetzler (1887) and Smith (1878) found Saprolegnia Jerax on eel larvae. The growth of this fungus was also observed on adult individuals of the European eel, Anguilla anguilla L. by Drew (1909) and Agersborg (1933) Tiffney (1939a, reported the presence of Saprolegnia parasitica on the specimens of the American ell, Anguilla rostrata (Lesueur), while Hoshina et al (1960)-on the Japanese eel, Anguilla japonica Temminck et Schlegel. Mycotic infections were also.…”
