VMS-Fish: A comprehensive application for zebrafish husbandry management (2025)

Zebrafish are widely used and increasingly adopted in developmental biology, disease modeling and tissue regeneration research. However, a freely available and user-friendly zebrafish husbandry management application has been lacking. Here, we developed an open-source fish management application, referred to as...

Preferred and optimal swimming speeds in rainbow trout (Oncorhynchus mykiss) at three temperatures (2025)

Sustained exercise in aquaculture is known to improve the health and growth of finfish. Implementing exercise regimes has become an increasing focus in aquaculture practice. This study examined the relationship between the preferred swimming speed (Upref) and the optimal swimming...

Acute effect of short-term benzocaine anesthesia on the skin mucus microbiome of Atlantic salmon (Salmo salar)

Routine aquaculture practices such as capture, transportation, and handling can disrupt the relationship between commensal and opportunistic bacteria in the fish skin microbiome. Anesthetic baths are a common welfare practice in aquaculture to reduce stress during handling. However, to date,...

Evaluation of tricaine methanesulfonate concentrations for flow anesthesia in zebrafish (Danio rerio) (2025)

Zebrafish (Danio rerio) are often anesthetized by immersion in buffered tricaine methanesulfonate (MS-222). Although commonly utilized, immersion anesthesia presents a shortcoming of lethal asphyxiation with increased duration of exposures. A newer technique that circumvents this issue, known as flow anesthesia,...

Heart rate monitoring during behavioral stress tests in bold and shy rainbow trout (Oncorhynchus mykiss)

Monitoring stress in captive fish is crucial for their welfare, but continuous physiological measures in unrestrained animals are challenging. Rainbow trout (Oncorhynchus mykiss) exhibit divergent personalities, ranging from bold to shy, which correlate with cortisol-mediated stress responses. To determine whether...

The welfare of farmed Nile tilapia: A review (2025)

Nile tilapia are, by absolute number of individuals, the most farmed species of fish today, yet we know little about how common husbandry practices impact their welfare. Despite their global importance, there is a notable lack of detailed, species-specific welfare...

Novel euthanasia technique for zebrafish using electric shock in standard group housing aquaria

Zebrafish are widely used in research, accounting for approximately 50% of all laboratory fish across Europe. Due to their rapid reproduction and aging, effective and practical euthanasia methods are necessary for managing large stocks. This study investigated whether adult zebrafish...
