Structure and Function of the Pituitary Gland in Gonadal Tumor-bearing and Normal Cyprinid Fish1
The F, generation hybrids of carp and goldfish exhibited a marked hyperplasia of pars distalis basophil (gonadotrophic) cells, which first became evident in 3to 4-year-old fish, the age at which carp and goldfish normally become sexually mature. Many of these hybrids also developed gonadal tumors, the genesis of which also coincided with the onset of gonadotroph proliferation. In these fish the...

متن کاملAcute toxicity test of detergent powder in silver carp (Hypophthalmicthys molitrix), common carp (Cyprinus carpio), goldfish (Carassius auratus) and roach (Rutilus rutilus caspicus)
Different pollutants have undesirable effects on aquatic ecosystems, detergent powder is one of the elements in the sewages so study on the effects of this factor on aquatic animals is crucial. The aim of the present study was to investigate acute effects of detergents as potentially dangerous additive to assess mortality effects of this product on some cultured fish. Silver Carp (Hypopht...
متن کاملBody color development and genetic analysis of hybrid transparent crucian carp (Carassius auratus).
The aim of this study was to investigate the genetic mechanism of the transparent trait in transparent crucian carp. We observed body color development in transparent crucian carp larvae and analyzed heredity of color in hybrids produced with red crucian carp, ornamental carp, and red purse carp. The results showed that the body color of the newly hatched larvae matured into the adult pattern a...
متن کاملThe genetic map of goldfish (Carassius auratus) provided insights to the divergent genome evolutions in the Cyprinidae family
A high-density linkage map of goldfish (Carassius auratus) was constructed using RNA-sequencing. This map consists of 50 linkage groups with 8,521 SNP markers and an average resolution of 0.62 cM. Approximately 84% of markers are in protein-coding genes orthologous to zebrafish proteins. We performed comparative genome analysis between zebrafish and medaka, common carp, grass carp, and goldfish...
