Six species of squat lobsters from a cold seep field in the northeastern South China Sea are studied. Two new species, Uroptychus jiaolongae n. sp. and U. spinulosus n. sp., are described, and their distinctions from the related species are detailed. Two species, Munidopsis tuberosa Osawa, Lin & Chan, 2008 and M. verrilli Benedict, 1902, are herein reported for the first time from a cold seep/h...

A life-long turnover of sensory and interneuronal populations has been documented in the olfactory pathways of both vertebrates and invertebrates, creating a situation where the axons of new afferent and interneuronal populations must insert into a highly specialized glomerular neuropil. A dense serotonergic innervation of the primary olfactory processing areas where these neurons synapse also ...

Adaptations to salinity are reviewed throughout development in both species of the genus Homarus. Some populations of homarid lobsters are known to inhabit coastal and estuarine areas where salinity fluctuates. Salinity tolerance varies during development, with 50 % lethal salinities (LS(50)) ranging from approximately 15-17 in larvae to approximately 12 in postlarvae and 10 in adults. La...

American lobster Homarus americanus landings in the Gulf of Maine have been steadily increasing since the 1980s. As a result, lobsters now support one of the most important fisheries in the USA and Canada. One hypothesis for this pattern is that lobsters have been released from predation as groundfish stocks declined, expanding both in abundance and habitat. Lobster habitat is typically rocky s...

This study describes experiments carried out to examine effects of the antiparasitic drug teflubenzuron, used in delousing farmed salmon, on a non-target species, the European lobster (Homarus gammarus). Juvenile lobsters were fed two doses of teflubenzuron, 10 and 20mg/kg successively for 7 days corresponding to a standard medication of the fish (10mg/kg day) and twice the standard dose (20mg/...

Ž . This study investigated the effect of temperature 18, 20, 22 and 248C on growth, feeding and metabolism of post-puerulus lobsters as part of a larger study of the culture potential of farming Ž . the southern rock lobster, Jasus edwardsii. There was no significant difference P)0.05 in the Ž . Ž . specific growth rates SGR at 18, 20 or 228C; however, growth decreased significantly P-0.05 Ž 2...

Species redistributions are one of the most prevalent changes observed in oceans worldwide due to climate change. One major challenges is being able predict temperature-driven species interactions and outcome these for marine communities complex nature indirect effects. In ocean-warming hotspot south-east Australia, ranges many have shifted poleward. The range eastern rock lobster Sagmariasus v...

Sustainability is one of the essential issues in utilizing lobster coastal waters Ayah, Kebumen Regency. Its management requires information on growth parameters and utilization status lobster. This study examines ornate spiny (Panulirus ornatus) Ayah’s water. The was conducted from November 2020 to January 2021. Lobster were analyzed by distribution frequency carapace length using ELEFAN I met...
