Regulation of steroid production and key genes in catfish Heteropneustes fossilis using recombinant gonadotropins
The two gonadotropins, FSH and LH, stimulate growth and development of the gonads through gonadal biosynthesis of steroid hormones and growth...

Post-spawning feed deprivation effects on testicular and ovarian maturation in the neotropical cichlid fish Cichlasoma dimerus
Many teleost fishes can withstand long feed deprivation periods, either due to an eventual lack of food or because of their behavior during...
