An order of CRUSTACEA that are parasitic on freshwater fish.

Growth and development of Argulus coregoni (Crustacea: Branchiura) on salmonid and cyprinid hosts. (1/7)

The obligate fish ectoparasite Argulus coregoni is strictly specific to salmonids and is very rarely found on other fish species. The ability of the parasite to grow and complete its life cycle on a cyprinid host, Rutilus rutilus, was compared with that on a typical salmonid host, Oncorhynchus mykiss. Rearing experiments were run for 42 d with newly hatched metanauplii in flow-through tanks. Body length and sex of the parasites were recorded every 5 d. Growth rates on O. mykiss exceeded those on R. rutilus from the age of 2 wk, at which time the parasites reached a length of about 3.5 mm. Males grew faster than females at the beginning of the experiment up to a length of 2.5 to 3.0 mm; thereafter, a faster growth rate was observed in females. In another experiment, association of parasites with the hosts was monitored and residence time defined as the period between attachment and first detachment from the host. Longer residence time was observed on O. mykiss than on R. rutilus; female parasites stayed on both fish species longer than did males. Faster growth of parasites could be associated with longer uninterrupted periods of attachment to hosts, since frequent detachment means higher energy losses and less time available for feeding. Despite its slower growth on R. rutilus, A. coregoni matured and laid egg clutches, but took 5 d longer than on O. mykiss. The potential of A. coregoni to complete its life cycle on cyprinids could have important ecological consequences, creating an infection reservoir when the main salmonid hosts are rare or temporarily missing.  (+info)

Efficacy of emamectin benzoate in the control of Argulus coregoni (Crustacea: Branchiura) on rainbow trout Oncorhynchus mykiss. (2/7)

Efficacy of in-feed treatment with emamectin benzoate (Slice) for the control of ectoparasitic Argulus coregoni on rainbow trout Oncorhynchus mykiss was tested under laboratory and field conditions. In both experiments fish were fed with fish feed to deliver a therapeutic dose of 0 (control) or 50 microg emamectin benzoate kg(-1) d(-1) (treatment) for a period of 7 d. After 3 d of challenge with A. coregoni in the laboratory, the infestation level in treated fish was lower than that observed in the controls (p < 0.001). Efficacy of 100% against newly hatched A. coregoni metanauplii and adults and 80% against juveniles was observed. In the field, trial medication was undertaken at 2 sections on a flow-through canal with 1 wk between treatments. Mean infestations of 100 to 200 A. coregoni per fish with 100% prevalence was recorded prior to medication. Following the treatment, the mean infestation of A. coregoni on fish declined to 31 lice per fish at Section A and 2.5 lice per fish at Section B. Then, after 28 d of treatment, the number of lice per fish was < 1 at Section A; in contrast the mean number of A. coregoni per fish at the control section was > 20. The prevalence of A. coregoni remained < 50% over a period of 72 d of treatment, but started to increase again thereafter. This suggests that emamectin benzoate concentration in fish remained at a level high enough to kill A. coregoni over a period of 9 wk. Emamectin benzoate was very effective in the control of A. coregoni infesting trout.  (+info)

Seasonal and vertical patterns of egg-laying by the freshwater fish louse Argulus foliaceus (Crustacea: Branchiura). (3/7)

Argulus foliaceus is a damaging fish ectoparasite for which new control measures are being developed based on egg-removal. In an attempt to develop further understanding of seasonal and vertical egg-laying patterns in this parasite, egg-laying activity was monitored over the period 14 April to 17 November 2003 in 2 rainbow trout Oncorhynchus mykiss fisheries in Northern Ireland, UK. At Site 1, egg-laying was continuous from 21 April to 17 November, when water temperature was above 8 to 10 degrees C. At Site 2, egg-laying was continuous from 4 June to 29 October. In the early months of the season, egg-laying was recorded mainly within the top 1 m of the water column; however, a significant shift to deep water egg-laying was recorded between 7 July and 17 November at Site 1 and between 20 August and 29 October at Site 2. Egg clutches were preferentially laid at depths of up to 8.5 m during this time (Site 2), a feature of egg-laying hitherto unappreciated. Temperature and dissolved oxygen did not differ significantly among depths, but there was an increase in water clarity over time. However, the precise environmental triggers for deep water egg-laying are still unclear. These new insights into the reproductive behaviour of this species will be useful in developing control methods based on egg-removal.  (+info)

Five ectoparasites from Turkish fish. (4/7)

Five ectoparasites were collected during the period of 2002-2005 from fish of Mediterranean Sea, Aegean Sea and inland waters of Turkey: Four crustaceans [Ergasilus mosulensis and Pennella instructa (Copepoda), Ceratothoa steindachneri (Isopoda) and Argulus foliaceus (Branchiura)] and one Annelida (Piscicola geometra) were found. The species, E. mosulensis, P. instructa and C. steindachneri have been reported for first time in Turkish waters, and A. foliaceus and P. geometra for the time from the Cavuscu Lake.  (+info)

I apologize, but "Arguloida" is not a medical term. It is a taxonomic category used in biology to classify certain types of crustaceans, specifically those that are parasitic and have a segmented body and multiple legs. They are also known as fish lice or sea lice.

If you have any questions related to medical terminology or health concerns, I would be happy to help answer them for you.

Ce jeu de données a été constitué depuis le 10/07/2019 (date de démarrage du carnet de plongée FFESSM avec observations). Le carnet naturaliste CROMIS a été lancé le 4 juin 2020 et sest ajouté au carnet standard. Ces observations sont essentiellement faites par des plongeurs de la FFESSM (au moins 62% par des plongeurs formés à la biologie sous-marine) et ponctuellement par des apnéistes, randonneurs palmés ou des promeneurs sur lestran ou en bord de cours deau ou lacs. Ces observations couvrent lensemble des embranchements marins mais certains sont peu ou pas observables en plongée. Les sites de plongée où ont été effectuées les observations sont tous identifiés et géographiquement localisés. La majorité des observations viennent des eaux françaises mais sont aussi issues de mers et docéans divers (Mer Rouge - Méditerranée, Océan Atlantique, Océan Indien et Océan Pacifique hors des eaux françaises). Certaines observations ont fait lobjet de photos validées ...
