Uncoupling protein 1 (UCP1) is of demonstrated importance in mammalian thermogenesis, and early hypotheses regarding the functions of the newly discovered UCP homologues, UCP2, UCP3 and others, have focused largely on their potential roles in thermogenesis. Here we report the amino acid sequences of two new UCPs from ectothermic vertebrates. UCPs from two fish species, the zebrafish (Danio reri...

The history and status of aquaculture genetics in Israel were reviewed a few years ago (Hulata 1995). The current report reviews trends and progress of the second half of the 1990s, and provides the vision and perspective for the next couple of years. Selective breeding work is currently focused mainly on tilapias (Oreochromis sp.) and gilthead seabream (Sparus aurata). Edible and ornamental co...

Between January and August 2002, a total of 74 fishes belonging to nine species (Alburnus caeruleus, Barbus luteus, B. sharpeyi, Carassius auratus, C. carassius, Ctenopharyngodon idella, Cyprinus carpio, Hypophathalmichthys molitrix Liza abu) were collected from three fish farms south Baghdad. Twenty-six parasites observed.They following : Three protozoa ( Ichthyophthirius multifiliis , Trichot...

background: occurrence of resistance against antibioticsand inadequate efficacy of some vaccines necessitates studies ofnatural immunostimulators in aquaculture. shrimps shell derivedfrom chitosan can be used as immune stimulators in fish.objectives: in this study, the effects of oral administration ofchitosan, derived from shrimp shell, on some immune responsesand disease resistance in cyprinu...

background: to solve the problems caused by using synthetic pesticides in agricultural fields and aquaculture ponds studies are being carried out on the feasibility of using biopesticides or plant extracts, which are less toxic. extensive research is being carried out by researchers globally to manufacture pesticides using plant extracts. the present study evaluated the effect of datura metel p...

in this survey, 54 specimens of common carp (cyprinus carpio) were collected from anzali wetland between august 2011 and july 2012. after recording biometric characteristics, routine necropsy and parasitology methods were used. totaly, 3165 individuals of parasites were isolated and identified from common carp. parasitofauna consisted of 10 species as follows: two protozoans, ichthyophthirius m...
