Example text

Opioids Most vertebrates have been shown to produce opioids (morphine-like compounds), the most common types of which are endorphins and encephalins. These are released in response to noxious stimuli, the adaptive significance of which must be to provide a level of analgesia that helps protect the animal against the adverse effects of tissue damage. The ability to produce these endorphins and encephalins and the presence of specific receptors for them is considered to be evidence for nociception and possibly pain perception.

While nociception is clearly seen in many groups, it is very difficult, while avoiding anthropomorphism, to be sure whether invertebrates experience pain. Despite this, or perhaps because of it, a precautionary approach should be adopted to handling and experimentation with invertebrates. Smith (1991) concluded that ‘the benefit of the doubt’ should be given to issues regarding pain and suffering when working with invertebrates and that the standards of husbandry and care ch03 February 5, 2008 32 16:46 Char Count= Anaesthetic and Sedative Techniques for Aquatic Animals afforded should always be respectful and promote ‘general well-being’.
