Zebrafish are increasingly used in neurobiological and behavioral studies. Possible stimuli to manipulate zebrafish behavior are being investigated. The presentation of colors appears to be one of the most used approaches, but there is much...
To optimize diet particle size for ingestion by zebrafish larvae, Danio rerio, a series of diet selection experiments were carried out using two different length classes: 5-day-old, first feeding larvae with a mean standard length...
Fin clipping of live fish under anesthesia is widely used to collect samples for DNA extraction. An alternative, potentially less invasive, approach involves obtaining samples by swabbing the skin of nonanesthetized fish. However, this method...
In recent years, a rapidly increasing number of scientific papers have been published that utilize zebrafish (Danio rerio) as an alternative model organism in the study of a wide range of biological phenomena from cancer...
The increasing importance of zebrafish as a biomedical model organism is reflected by the steadily growing number of publications and laboratories working with this species. Regulatory recommendations for euthanasia as issued in Directive 2010/63/EU are...
Rotifers are now becoming a standard live feed for first-feeding larvae, because of their easy rearing protocol and improved growth and survival rate, compared with other fish feed, paramecia, and processed powder fish feeds. In...
Zebrafish are a valuable model organism in biomedical research. Their rapid development, ability to model human diseases, utility for testing genetic variants identified from next-generation sequencing, amenity to CRISPR mutagenesis, and potential for therapeutic compound...
Comparative studies on neural plasticity in non-mammalian vertebrates are increasingly promoted as an important complement to mammalian models. In teleost fishes the number of brain cells increases with age, body weight, and body length throughout...
Large-scale aquaculture facilities require highly optimized husbandry protocols that maximize fecundity and embryo health while minimizing cost and effort. Although zebrafish are being increasingly used for preclinical drug screens, functional genomic research and toxicological and...
Information about the welfare and husbandry of pet and laboratory fish is scarce although millions of fish are sold in pet shops and used in laboratory research every year. Inadequate housing conditions can cause behavioural...
