Guidelines for protecting and promoting insect welfare in research

These guidelines were developed by the leadership of the Insect Welfare Research Society (IWRS). They are intended to provide guidance to individuals researching insects, in laboratory, field, education, and industry contexts. The guidelines are informed by standard principles of animal...

Perspective: Opportunities for advancing aquatic invertebrate welfare

Welfare considerations and regulations for invertebrates have lagged behind those for vertebrates, despite invertebrates comprising more than 95% of earth's species. Humans interact with and use aquatic invertebrates for exhibition in zoos and aquaria, as pets, research subjects, and important...

Effect of animal stocking density and habitat enrichment on survival and vitality of wild green shore crabs, Carcinus maenas, maintained in the laboratory

The wide geographic distribution, large size and ease of capture has led to decapod crustaceans being used extensively in laboratory experiments. Recently in the United Kingdom decapod crustaceans were listed as sentient beings, resulting in their inclusion in animal care...

Non-invasive methods for assessing the welfare of farmed white-leg shrimp (Penaeus vannamei)

Gradually, concern for the welfare of aquatic invertebrates produced on a commercial/industrial scale is crossing the boundaries of science and becoming a demand of other societal actors. The objective of this paper is to propose protocols for assessing the Penaeus...

Effects of environmental enrichment on the behavior of Octopus vulgaris in a recirculating aquaculture system

Octopus vulgaris is a commercially valuable species. It is overexploited in the natural environment and is considered to be an innovative species for aquaculture. However, large-scale farming is generally designed only based on economic requirements, disregarding any form of enrichment...

Is it time for insect researchers to consider their subjects’ welfare?

Recent evidence suggests that at least some insect species might plausibly feel pain. These findings should prompt researchers to think about the welfare implications of insect experiments.

Aquarium tank design is integral to the elimination of mantle abrasion in the captive curled octopus (Eledone cirrhosa): A case study at Macduff Marine Aquarium

Macduff Marine Aquarium is a native species aquarium situated on the Moray Firth coastline and houses the curled octopus, Eledone cirrhosa, for public display. Historically, the designated octopus display tank has been in-keeping with the overall theme of the aquarium,...

Goal-oriented behavioural and environmental enrichment in aquarium species

Environmental enrichment is a common tool used in zoo and aquarium settings to provide mental and physical stimulation to animals under human care. This paper aims to present a primary approach to goal-oriented environmental and behavioural enrichment following a simplified...

Anesthetic efficacy of magnesium chloride and ethyl alcohol in temperate octopus and cuttlefish species

Cephalopods are important in biologic and biomedical research, yet relatively little objective information is available to guide researchers and veterinarians regarding the best methods for anesthetizing these animals for various experimental procedures. Recent studies demonstrate that ethyl alcohol and magnesium...

The use of a species-specific health and welfare assessment tool for the giant Pacific octopus, Enteroctopus dofleini

Cephalopods are increasingly viewed as sentient animals that require the same welfare consideration as their vertebrate counterparts. In this study, an observational welfare assessment tool developed by the EU Directive was revised to be species-specific for the giant Pacific octopus,...
