Goldfish (Carassius auratus) matching geometric and featural cues: a reinterpretation of some of the data of Vargas, López, Salas, and Thinus-Blanc (2004).

Effects of zinc sulfate (ZnSO4) in diet on the growth performance and gene expression of Insulin-like growth factor-1 (IGF-1) and Ghrelin in goldfish (Carassius auratus)

The zinc element (Zn) is one of the micronutrients and an essential element of the body which has some deleterious and irreparable effects on growth in case of lack it. Thus, we aimed to assess IGF-1 in goldfish with Zn deficiency and to investigate the effect of Zn supplementation on these parameters. Goldfish  (Carassius auratus)  juvenile  (3.5 g)  were fed purified diets based on casein as ...

Effect of Light and Music on Growth Performance and Survival Rate of Goldfish (Carassius auratus)

 Environmental enrichment is one of the methods for improving fish growth performance. In the present trial, the effects of both light color and music on growth performance and survival of goldfish (Carassius auratus) (initial mean weight: 4.15±0.08 g) were investigated for 2 months. Two light color treatments (red light and white light) and three music treatments (M0: without music, M30:30 min...

Effects of cortisol on tesicular apoptosis in goldfish (Carassius auratus)

Apoptosis is a programmed cell death that has been attributed to the action of stress hormones, such as cortisol. We investigated the in vitro effect of cortisol in goldfish (Carassius auratus) mature (GSI: 2.75-4.65) or immature (GSI: 1.94-2.4) testes. Testes were taken out and transferred into culture medium (M 199), cut into 20 mm thick slices and supplemented with fetal bovine serum (FBS), ...

Effects of different protein sources on growth performance and food consumption of goldfish, Carassius auratus

Acute 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...
