The Norway lobster, Nephrops norvegicus, is a valuable and commonly exported European decapod crustacean, which experiences stress from point of capture and onward transport. Stressors such as air exposure duration (i.e. emersion period) and air temperature have been studied previously. We investigated whether mortality could be reduced by decreasing road vibrations during transport, and how physiological stress measurements were influenced in a transport simulation experiment, reflecting a typical short road journey along a supply chain. Baseline haemolymph samples were taken from lobsters sampled immediately after commercial capture using static traps (lobster pots). Individuals were emersed for one hour, either immobile or with continuous shaking; the latter to simulate conditions occurring during transport. Both treatments significantly increased Total Haemocyte Counts (THC) and serum glucose, lactate and ammonium concentrations compared to baseline animals. Individuals subjected to continuous shaking showed higher glucose and ammonium concentrations compared to individuals maintained immobile. We conclude that shaking appears to influence the physiological responses of N. norvegicus in addition to the effects of emersion alone, and the reduction of road vibrations (e.g. via simple cushioning) can reduce post-transport mortality.

Species in Cymothoidae (Crustacea: Isopoda) are cosmopolitan parasite infesting marine, freshwater and brackish water fishes. In Cymothoidae, Anilocra and Nerocila species have an elongated juvenile stage called the aegathoid stage. A total of 831 Japanese halfbeaks Hyporhamphus sajori (Beloniformes: Hemiramphidae) were collected from 11 sites in Japan. The aegathoid stage was seen infesting a Japanese halfbeak collected from Osaki-Shimojima Island, Kure City, Hiroshima Prefecture, and identified as Anilocra clupei by DNA barcoding using the COI and 16S rRNA sequences. The morphology of this individual was also almost identical to the aegathoid stage of A. clupei in the previous study. The prevalence of the aegathoid stage of A. clupei on Japanese halfbeaks was very low at 0.12% in all of Japan and 0.93% in the coast of Osaki-Shimojima Island. Aegathoid stages of A. clupei may have lower host-specificity than adult females, and be able to infest more comprehensive species of fish, which may increase the survivability of the aegathoid stages.
