Anesthesia and humane euthanasia methods for king worm larvae (Zophobas morio)

A growing spotlight on insect welfare as research subjects, fodder for vertebrate animals, and patients for veterinarians highlights the need to establish humane euthanasia methods for these species. An insect of increasing commercial importance is the king worm (Zophobas morio),...

Food-related substrate preference in juveniles seastar Echinaster (Othilia) brasiliensis (Müller & Troschel,1842) in captivity

There are only a few studies that describe the larval development of Echinaster or aspects on culture systems for the genus. For starfishes, the choice of suitable substrates has received special attention since it could influence the acid–base balance of...

Practical euthanasia method for common sea stars (Asterias rubens) that allows for high-quality RNA sampling

Sea stars in research are often lethally sampled without available methodology to render them insensible prior to sampling due to concerns over sufficient sample quality for applied molecular techniques. The objectives of this study were to describe an inexpensive and...

Refining housing, husbandry and care for animals used in studies involving biotelemetry

Biotelemetry can contribute towards reducing animal numbers and suffering in disciplines including physiology, pharmacology and behavioural research. However, the technique can also cause harm to animals, making biotelemetry a ‘refinement that needs refining'. Current welfare issues relating to the housing...

A three-dimensional habitat for C

As we learn more about the importance of gene-environment interactions and the effects of environmental enrichment, it becomes evident that minimalistic laboratory conditions can affect gene expression patterns and behaviors of model organisms. In the laboratory, Caenorhabditis elegans is generally...
