We studied a natural infection of the oligochaete Branchiura sowerbyi Beddard, 1892 with the Raabeia-type actinosporean stage of Myxobolus lentisuturalis Dyková, Fiala et Nie, 2002 which infected goldfish Carassius auratus auratus (L.) in Italy, using molecular analysis of the SSU rRNA gene. The existence of intraoligochaete development shows that this parasite follows the life-cycle pattern de...

Fresh water fish, such as carp (Cyprinus carpio), koi koki (Carassius auratus) and comet auratus have great opportunities for developing aquaculture in Indonesia. However, the presence of argulosis disease caused by ectoparasites Argulus sp. be one obstacles. This parasitic infestation can cause fish to experience a decrease body weight, weakness, bleeding, secondary infection, sale value even ...

Literature reviews of all references concerning the parasitic fauna of fishes in fish farms of Babylon province, middle of Iraq, showed that a total of 92 valid parasite species are so far known from the common carp (Cyprinus carpio), the grass carp (Ctenopharyngodon idella), and the silver carp (Hypophthalmichthys molitrix) as well as from three freshwater fish species (Carassius auratus, Liza...

argulus foliaceus (crustacea: branchiura), or the fish louse, is an ectoparasite of the skin or gill of the fresh water fish species. clinical signs in infected fish include scratching on aquarium walls, erratic swimming, and poor growth. it causes pathological changes due to direct tissue dam­age and secondary infections. in the present study, lionhead goldfish (carassius auratus ), taken from...

Aquarium fish trade is one of the global industrial areas that gradually increasing in popularity throughout world. The sectors all over world as well Turkey major causes spread invasive species. non-native aquarium species known for existence Turkish inland waters these days. In this study, Carassius auratus were recorded first time Ordu province middle Black Sea Region. C. was stocked Ulugöl ...

OBJECTIVE To study the biological effects of nanoscale copper oxide (nCuO), zinc oxide (nZnO), cerium dioxide (nCeO2) and their mixtures on Carassius auratus. METHODS Juvenile fish (Carassius auratus) were exposed to aqueous suspensions of nCuO, nZnO, and nCeO2 (alone and in mixtures) at concentrations of 20, 40, 80, 160, and 320 mg/L. The biomarkers-acetylcholinesterase (AChE) in brain, sodi...

1. The effect of thiocyanate on chloride and sodium fluxes across the gill was studied in the goldfish Carassius auratus. At low external chloride concentrations, addition of SCN- to the bathing solution markedly inhibited chloride influx and efflux, the net flux being reversed, SCN- injection was without effect. SCN- had no effect on sodium fluxes when injected or added to the external medium....
