Study on biological performance of recombinant GnRH as a spawning – inducing agent for goldfish (Carassius auratus)
Different hormones are used to induce final sexual maturation in fish breeders and one of these hormones is different analogue of gonadotropin releasing hormone (GnRH) with different trade names. The aim of this study was to evaluate the biological activity of recombinant GnRH produced in the laboratory of Sari Agricultural Sciences and Natural Resources University on the induction and synchron...
متن کاملThe innate immunity changes of the female anadromous hilsa shad, Tenualosa ilisha , during spawning and post spawning season
Tenualosa ilisha (Hamilton) is a valuable migratory fish belonging to the family Clupeidae and it is distributed in a wide area from the Persian Gulf to coasts of Pakistan and China’s southern sea. The aim of the present study was to investigate the changes occurring in innate immunity parameters during upstream migration and comparing them to those during post spawning. Sixty mature female hil...

متن کاملCompensatory cleaner-seeking behavior following spawning in female yellowtail damselfish
Marine reef fishes may spend a significant proportion of their daily activity budgets visiting cleaning stations. Nevertheless, the roles of ectoparasites and of interactions with cleaners in shaping patterns of diel activity in these fishes have been largely ignored, possibly because the importance of cleaning for the hosts remains controversial. In diurnal species, a peak in ectoparasite infe...
متن کاملChanges in gonadotropin and ovarian steroids associated with oocytes maturation during spawning induction in the carp.
The present study correlates the profiles of certain ovarian steroid hormones with stages of oocyte maturation in common carp induced to spawn by classic hypophysation. Sixteen females were injected at midday with a calibrated homologous pituitary extract (cPE) containing 0.07 mg immunoreactive cGTH/kg body wt, as a priming dose. Ten of those females were injected 11 hr later with cPE containin...
