Argulus foliaceus (Crustacea: Branchiura), or the fish louse, is an ectoparasite of the skin or gill of the fresh water fish species. Clinical signs in infected fish include scratching on aquarium walls, erratic swimming, and poor growth. It causes pathological changes due to direct tissue damage and secondary infections. In the present study, lionhead goldfish (Carassius auratus), taken from a...

Majalaya carp is a freshwater fish that has important economic value and widespread in Indonesia. Goldfish the most cultivated because it many advantages both physiologically genetically. Several factors of assessment selection superior brood stock can be considered cultivation goldfish cultivators are; ideal body weight, movement, physical deformities, scales, base tail. All these help decisio...

BACKGROUND Goldfish, Carassius auratus, have experienced strong anthropogenic selection during their evolutionary history, generating a tremendous extent of morphological variation relative to that in native Carassius. To locate the geographic origin of goldfish, we analyzed nucleotide sequences from part of the control region (CR) and the entire cytochrome b (Cytb) mitochondrial DNA genes for ...

Goldfish scooping is one of the traditional Japanese play. In general, people scoop goldfish in a shallow water tank using a fragile water-thin dipper. In this paper, we describe virtual goldfish scooping system using haptic device and stereoscopic display.

This research aims to examine the effect of adding various sources natural ß-Carotene obtained from sweet potato flour, carrot flour and pumpkin color brightness Goldfish. The was carried out December 2021 February 2022 at Aquatic Animal Physiology Laboratory Building 2, Faculty Fisheries Marine Sciences, Padjadjaran University. experimental design used in this study a completely randomized (CR...

BACKGROUND Artificial selection of postembryonic features is known to have established morphological variation in goldfish (Carassius auratus). Although previous studies have suggested that goldfish and zebrafish are almost directly comparable at the embryonic level, little is known at the postembryonic level. RESULTS Here, we categorized the postembryonic developmental process in the wild-ty...

It is known that olfaction is essential for the occurrence of sexual behavior in male goldfish. Sex pheromones from ovulatory females elicit male sexual behavior, chasing, and sperm releasing act. In female goldfish, ovarian prostaglandin F2α (PGF) elicits female sexual behavior, egg releasing act. It has been considered that olfaction does not affect sexual behavior in female goldfish. In the ...
