This study aimed to evaluate the efficacy of silver sulfate (AgSO4) as a toxicant in goldfish (Carassiusauratus). One hundred and forty-seven live specimens of C. auratus were obtained and exposed to 1, 10, 100, 500, 1000 and 2000 ppm of AgSO4for 96 hours. There was one control group (no AgSO4) and three replicates. The physicochemical properties of water and the following parameters were const...

Ikan Mas Koki (Carrasius auratus) merupakan salah ikan hias yang memiliki nilai ekonomis tinggi dan pasngsa pasar stabil. Pakan satu faktor penting untuk meningkatkan pertumbuhan mas koki. baik akan bedampak pada koki lebih cepet. Magot alternatif pakan alami dapat digunakan Penambahan tepung magot kering memberikan dampak positif Pada penelitian ini dilakukan penambahan dengan dosis K (100% bu...

This study was carried out to evaluate the effect of different levels of garlic (Allium sativum) on growth survival and nutritional characteristics of goldfish (Carassius auratus). For this purpose, 180 goldfish with an average initial weight of 1.18± 0.08 g were introduced randomly into 12 aquaria (50×30×40 cm) at 4 groups. After one week feeding on basal diet, the treatments were fed on exper...

We systematically classified goldfish ganglion cells according to their spatial summation properties using the same techniques and criteria used in cat and monkey research. Results show that goldfish ganglion cells can be classified as X-, Y-, or W-like based on their responses to contrast-reversal gratings. Like cat X cells, goldfish X-like cells display linear spatial summation. Goldfish Y-li...

Intracerebroventricular (ICV) administration of gonadotropin-releasing hormone II (GnRH II), which plays a crucial role in the regulation of reproduction in vertebrates, markedly reduces food intake in goldfish. However, the neurochemical pathways involved in the anorexigenic action of GnRH II and its interaction with other neuropeptides have not yet been identified. Alpha-melanocyte-stimulatin...

Permeability properties of the goldfish gill epithelium were examined in vivo and in vitro following exposure to ion-poor water (IPW) conditions. In gill tissue of IPW-acclimated goldfish, transcript abundance of tight junction (TJ) proteins occludin, claudin-b, -d, -e, -h, -7, and -8d increased, whereas ZO-1 and claudin 12 mRNA decreased and claudin-c was unaltered. In association with these c...
