Baltic larval cod Gadus morhua are infested with a protistan endoparasite in the yolk sac
A protistan endoparasite was d~scovered in the yolk of embryos and larvae of cod Gadus morhua L. from the Baltic. The prevalence of infestation ranged from 0 to 30 ":>. Two stages of the parasite were identified under transmiss~on electron microscopy. One stage was apparently mononucleated; the other stage was multinucleated and seemed to be b reak~ng-up into numerous, mononucleated organisms. ...
متن کاملGenomic Sequencing of Ranaviruses Isolated from Turbot (Scophthalmus maximus) and Atlantic Cod (Gadus morhua)
Ranaviruses have been isolated from Atlantic cod (Gadus morhua) and turbot (Scophthalmus maximus) in Denmark. Phylogenomic analyses revealed that these two ranaviruses are nearly identical and form a distinct clade at the base of the ranavirus tree branching off near other fish ranaviruses.
متن کاملHorizontal transmission of nervous necrosis virus between turbot Scophthalmus maximus and Atlantic cod Gadus morhua using cohabitation challenge.
Experimental horizontal transmission of nervous necrosis virus (NNV) originating from halibut Hippoglossus hippoglossus was studied through cohabitation of intraperitoneally (i.p.) injected fish with uninfected fish for 125 d. The experimental groups consisted of i.p. injected turbot Scophthalmus maximus or i.p. injected Atlantic salmon Salmo salar with turbot, salmon or Atlantic cod Gadus morh...

It occurs in the Baltic and in the Mediterranean, as well as in the Black Sea, where a subspecies Psetta maxima maeotica has been described (1). It also exists in the Sout...
متن کاملIodine nutrition and toxicity in Atlantic cod (Gadus morhua) larvae
Copepods as feed promote better growth and development in marine fish larvae than rotifers. However, unlike rotifers, copepods contain several minerals such as iodine (I), at potentially toxic levels. Iodine is an essential trace element and both under and over supply of I can inhibit the production of the I containing thyroid hormones. It is unknown whether marine fish larvae require copepod l...
