Daily Patterns in Parasite Processes: Diel Variation in Fish Louse Transcriptomes

International Journal for Parasitology, 2022
Parasites, similar to all other organisms, time themselves to environmental cues using a molecular clock to generate and maintain rhythms. Chronotherapeutic (timed treatment) techniques based on such rhythms offer great potential for improving control of chronic, problematic parasites.

Control of Freshwater Fish Louse Argulus coregoni: A Step Towards an Integrated Management Strategy [PDF]

Diseases of Aquatic Organisms, 2008
Harmful infections by ectoparasites of the genus Argulus occur repeatedly in freshwater fish farming operations where the management has largely been ineffective. Preventative methods and regular monitoring are rarely applied, so that chemical interventions become necessary.

Identification and characterisation of hemocyanin of the fish louse Argulus (Crustacea: Branchiura)

Journal of Comparative Physiology B, 2015
Hemocyanin transports oxygen in the hemolymph of many arthropod species. Within the crustaceans, this copper-containing protein was thought to be restricted to Malacostraca, while other crustacean classes were assumed to employ hemoglobin or lack any respiratory protein.

Biological control of the fish louse in a rainbow trout fishery

Journal of Fish Biology, 2002
Novel egg‐laying boards were found to be effective in the biological control of the freshwater fish louse Argulus foliaceus in a 12·9 ha rainbow trout Oncorhynchus mykiss fishery which had a high prevalence and intensity of infection of juvenile parasites in the early spring of 1999. Approximately 228 000 egg clutches were harvested during an extensive

Ornamental fish mortality reveals an old parasite introduction: A case study of Koi carp and fish louse

Veterinary Parasitology: Regional Studies and Reports
Koi carp are globally known for their colors and cultural significance. The introduction of these fish to new environments poses a threat to local biodiversity, in addition to releasing parasites, such as argulid ectoparasites. This study presents a record of Argulus japonicus infecting carp in an artificial lake in Southern Brazil using morphological ...

Countershading by physiological colour change in the fish louse Anilocra physodes L. (Crustacea: Isopoda)

Oecologia, 1982
Specimens of the fish louse Anilocra physodes L. from the Mediterranean Sea exhibited a striking colour asymmetry in their dorsal pigmentation: one longitudinal half of their back was dark, the opposite half was lightcoloured. The dark side corresponded with the physiological upper side when the fish louse was attached to the flank of a host fish.The ...

Transcriptional analysis of the common carp (Cyprinus carpio L.) immune response to the fish louse Argulus japonicus Thiele (Crustacea: Branchiura)

Fish & Shellfish Immunology, 2008
In the present study we investigated changes in transcription levels of a panel of selected immune relevant genes in peripheral blood leucocytes (PBL) and skin samples collected from carp exposed to larval Argulus japonicus. We show that in skin up-regulation of gene transcription of the chemokine CXCa, and to a lesser extent the chemokine receptor ...

Infection of hottentot Pachymetopon blochii by the fish louse Anilocra capensis (Crustacea: Isopoda) in False Bay, South Africa

African Zoology, 2001
The frequency of occurrence, location on the host, abundance, and size and sex distributions of ectoparasitic isopods, Anilocra capensis, on hottentot  Pachymetopon blochii from False Bay, South Africa, were investigated. A. capensis occurred on 5.2 % of examined hosts and were usually attached above the  operculum, posterodorsally to the eye. They did
