The wide geographic distribution, large size and ease of capture has led to decapod crustaceans being used extensively in laboratory experiments. Recently the United Kingdom were listed as sentient beings, resulting their inclusion animal care protocols. Ironically, little is known about how captive conditions affect survival general condition wild crustaceans. We green shore crab, Carcinus maenas, investigate effects stocking density shelter on vitality indices during a 6 month period laboratory. Neither nor presence affected survival. Stocking also had no effect (limb loss, claw strength, BRIX, righting time, leg flare retraction). did number limbs lost retraction response, but other indices. All changed, mortality increased over independent treatment: this became most apparent after 8 11 weeks storage This decline may have been due repeated handling crabs, rather than conditions. In support this, untracked, non-handled (control) individuals sustained 4% rate compared with 67% experimental crabs period. Although simple monitoring biweekly tests only produced transient short-term stress events, time apparently cumulative deterioration health. Bringing into holding them, even modest manipulation, result high rates. Researchers committees need be aware that invertebrates will respond very differently laboratory-bred vertebrates, plan experiments accordingly.
