The rearing of fish fry in illuminated cages is one of the methods used before fish release into water bodies. The aim of the study was to investigate the peculiarities of infestation with Argulus foliaceus L. of the fry of pike Esox lucius (L.), pike-perch Sander lucioperca (L.), bream Abramis brama (L.), vimba Vimba vimba (L.) and peled Coregonus peled (Gmel.) reared in illuminated cages. The...

We studied the fine structure of some classical and six variant mitochondria from different tissues viz. proboscis gland, spinal gland, ovary, testis, and muscle of a fish ectoparasite, Argulus bengalensis. In the proboscis gland and spinal gland, mitochondria are protected within vesicle to preserve their structure and activity from exposure to glandular synthesis for its parasitic mode of fee...

A new species of Argulus is described based on 18 specimens taken from the salamander ("achoque" or "ajolote") Ambystoma dumerilii Duges, collected in Lake Patzcuaro, Michoacan, Mexico. Diagnostic characters include the shape of the respiratory areas, number of sclerites in suction cup rods, and structures on the legs of males. Females are heavily stippled, whereas males have a very distinctive...

This study was the first investigation of communities and infracommunities of parasites of Hemibrycon surinamensis. All the fish collected in a tributary of the Amazon river were parasitized by one or more parasite species. The Brillouin diversity index (HB) was 0.46 ± 0.28 and the mean species richness was 3.5 ± 1.2 parasites per host. A total of 14,734 parasites were collected, including Icht...

Toll like-receptors (TLRs) are pattern recognition receptors (PRRs) that are involved in the recognition of the pathogens based on their conserved motifs, called pathogen associated molecular patterns (PAMPs). As the information on the TLR/s involved in the recognition of the parasitic ligand is limited, the objective of this study was to assess the expression profiles of six different TLRs (2,...

The parasite fauna of 50 specimens of spiny eel obtained from two lakes, Zarivar (in Kurdistan province) and Parishan (in Fars province) and one river, Heleh (Booshehr province) were examined during the year 2003. A total of nine parasite species were found. Gills of spiny eel were infected with Ichthyophthirius multifiliis , Trichodina pediculus (protozoa) and Mastacembelocleidus heteranchorus...
