If crustaceans feel pain, there are ethical and animal welfare implications including the consequences of exposure to pollutants, and practices involving commercial and recreational fishing, aquaculture, food preparation and for crustaceans used in scientific research.
Scientists called for humane ways to handle crabs, lobsters, and other shellfish in the kitchen after showing for the first time that crustaceans indeed feel pain.. Boiling lobsters and crabs ...
However, careful control is required because physiological changes can occur due to noxious, but non-pain related events, e.g. cardiac and respiratory activity in crustaceans is highly sensitive and responds to changes in water level, various chemicals and activity during aggressive encounters.
The ethics of uncertain sentience refers to questions surrounding the treatment of and moral obligations towards individuals whose sentience—the capacity to subjectively sense and feel—and resulting ability to experience pain is uncertain; the topic has been particularly discussed within the field of animal ethics, with the precautionary ...
[12] [13] Animal welfare groups have objected to this practice on the basis that octopuses can experience pain. [14] In support of this, since September 2010, octopuses being used for scientific purposes in the European Union are protected by EU Directive 2010/63/EU "as there is scientific evidence of their ability to experience pain, suffering ...
Though it has been argued that most invertebrates do not feel pain, [28] [29] [30] there is some evidence that invertebrates, especially the decapod crustaceans (e.g. crabs and lobsters) and cephalopods (e.g. octopuses), exhibit behavioural and physiological reactions indicating they may have the capacity for this experience.
