Oogenesis control in multispawning blue gourami (Trichogaster trichopterus) as a model for the Anabantidae family

Gad Degani

Abstract :

 This review discusses a model of environmental, behavioral and hormonal involvement, and its influence on oogenesis in female blue gourami, Trichogaster trichopterus, which belongs to the Anabantidae family, based on more than 15 years of studies. The model presents the effect of environmental factors and pheromones (steroid glucoronides) on oogenesis and ain–pituitary hormones gene expression in blue gourami females. Environmental factors and pheromones affect gonadotropinreleasing hormone (GnRH1 and 3), pituitary adenylate cyclase–activating polypeptide (PACAP) and its related peptide (PRP), which act on follicle–stimulating hormone (FSH), luteinizing hormone (LH), growth hormone (GH) and prolactin (PRL). 17β–estradiol (E2) and testosterone (T) increased during vitellogenesis (VTL) at a relatively high level in the plasma, and 17α,20β–dihydroxy–4–pregnen–3–one (17,20P) increased during maturation and ovulation in blue gourami. In summary, this review proposes a quality model of the Anabantidae family combining important parameters, including water (temperature and salinity), the sexual behavior of males, pheromones and hormones involved in the ain–pituitary–gonad (BPG) axis, and the effect on oogenesis and reproduction of females.
