Fishes can regenerate lateral line and inner ear sensory hair cells that have been lost following exposure to ototoxic antibiotics. However, regenerative capabilities following noise exposure have not been explored in fish. Moreover, nothing is known about the functional relationship between hair cell damage and hearing loss, or the time course of morphological versus functional recovery in fis...

Invasive alien species (IAS) are major drivers of global biodiversity loss, and the poorly regulated international pet trade is a source emerging future invaders. Predictions likely ecological impacts risks such IAS have been significantly enhanced in recent years with new metrics, which require application to many more actual potential IAS. Hence, this study assesses two readily available spec...

A 60-day indoor growth trial was carried out to investigate the effects of dietary replacement fish meal (FM) protein with black soldier fly (Hermetia illucens) larvae (BSFLM) at graded concentrations on bio-growth parameters, whole-body chemical composition, digestive enzyme activity, muscle-growth-related gene expression and haemato-biochemical responses goldfish (Carassius auratus) juveniles...

Nesfatin-1 is an anorexigen in goldfish. In the present study, we provide novel data indicating the presence and regulatory effects of nesfatin-1 on the hypothalamo-pituitary-ovarian (HPO) axis of goldfish. Nucleobindin-2 (NUCB2)/nesfatin-1-like immunoreactive (ir) cells are present in the hypothalamus and in the pituitary, suggesting a hypophysiotropic role for nesfatin-1. NUCB2/nesfatin-1-lik...

The present research was aimed to study the effects of different sources of carotenoids and their varying concentrations on the reproductive functions of goldfish. The study was carried out in seven treatments with three replicates at the Bony Fish Hatchery Complex (Rasht, Iran) from December 2011 to May 2012. Experimental diets containing 50, 100, and 150 mg kg-1 astaxanthin and 50, 100, and 1...

 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...

Background: Goldfishes are used as an ideal model for nutritional studies in larval and juvenile cyprinids. However, of the limited published data that is available on goldfish, protein requirements have varied from 29% to 53% goldfish larvae. So present study was undertaken determine growth performance C. auratus fed with different dietary lipid levels develop nutritionally balanced diets. Met...

EXPERIMENTS in our laboratory have demonstrated that memory fixation of a shockavoidance task in the goldfish can be blocked by puromycin or acetoxycycloheximide (AXM)$ when administered within 1 hr after training, but not at later times (AGRANOFF and KLINGER, 1964; DAVIS, BRIGHT and AGRANOFF, 1965; AGRANOFF, DAVIS and BRINK, 1965, 1966). The present studies report the effects of these compound...

The denatured catalytic polypeptide of (Na+,K+)-ATPase of goldfish brain was purified and identified as the 32P-labeled phosphoprotein. The protein served as immunogen for the preparation of rabbit antisera for immunohistochemical application t o goldfish tissue sections, using t h e peroxidase-antiperoxidase indirect method. Labeling in brain cross-sections appears primarily in fibers of the o...
