Shell disease (SD) has been observed in lobster populations for almost a hundred years, but recently, rates of an epizootic form of shell disease (ESD) have increased in the southern New England (USA) area. A large proportion of fish in the diet of American lobsters Homarus americanus has been linked to increased rates of SD. Therefore, the use of fish as lobster bait may be linked to increased...

Diseases of lobster shells have a significant impact on fishing industries but the risk of disease transmission between different lobster species has yet to be properly investigated. This study compared bacterial biofilm communities from American (Homarus americanus) and European lobsters (H. gammarus), to assess both healthy cuticle and diseased cuticle during lesion formation. Culture-indepen...

A complex nervous system enables spiny lobsters to have a rich behavioural repertoire. The present paper discusses the ways in which the sensory systems of the Caribbean spiny lobster, Panulirus argus , particularly its chemosensory systems, are involved in feeding behaviour. It addresses the neural mechanisms of three aspects of their food-finding ability: detection, identification, and discri...

The pathogenic virus Panulirus argus virus 1 (PaV1) was first discovered in Caribbean spiny lobsters Panulirus argus from the Florida Keys (USA) in 1999 and has since been reported in Belize, Mexico, and Cuba; its distribution in the wider Caribbean is unknown. We collected tissue samples from adult spiny lobsters from 30 locations in 14 countries bordering the Caribbean Sea and used molecular ...

The Caribbean spiny lobster (Panulirus argus) supports the most economically valuable fishery in the Caribbean. In Florida, USA, the majority of the catch is landed in traps “baited” with live, sublegal-sized lobsters that attract other lobsters due to their social nature. This species is also commonly infected by the pathogenic virus Panulirus argus Virus 1 (PaV1). Here we describe a polymeras...

To date, the natural substratum preferences of early benthic phase (EBP) European lobsters (Homarus gammarus) remain largely unknown. This study utilised a large scale mesocosm experiment to determine if the animal favours cobble ground, similar to its American counterpart (Homarus americanus), or has other substratum preferences. Postlarvae were provided with the choice of settling on four nat...

Crustaceans exhibit a remarkable variation in their feeding habits and food type, but most knowledge on carbohydrate digestion and utilization in this group has come from research on few species. The aim of this study was to make an integrative analysis of dietary carbohydrate utilization in the spiny lobster Panulirus argus. We used complementary methodologies such as different assessments of ...

Despite being one of the most productive fisheries in the Northwest Atlantic, much remains unknown about the natural reproductive dynamics of American lobsters. Recent work in exploited crustacean populations (crabs and lobsters) suggests that there are circumstances where mature females are unable to achieve their full reproductive potential due to sperm limitation. To examine this possibility...

Palinurids, also known as spiny lobsters, are high-value seafood, which is economically important for many European and Asian seafood trades. However, the reduction of wild lobster populations produces a need developing alternative renewable strategies to meet current future demands. Aquaculture lobsters has potential become major economic importance in coming years with growing markets Asia, E...

Five scyllarine lobsters are recorded from Taiwan for the first time. They are Bathyarctus rubens (Alcock & Anderson, 1894), Biarctus sordidus (Stimpson, 1860), Chelarctus aureus (Holthuis, 1963), Crenarctus bicuspidatus (De Man, 1905) and Petrarctus veliger Holthuis, 2002. The distributions of B. rubens, C. aureus and P. veliger are extended northwards to Taiwan. Distinguishing characters of t...
