“…Palaemon macrodactylus Rathbun, 1902, was also recently found at increasing densities (Béguer et al, 2007). This species is an exotic invasive shrimp native from Japan, Korea, and China (Rathbun, 1902;Kubo, 1942) and recently recorded in several European estuaries (Ashelby et al, 2004;Cuesta et al, 2004;d'Udekem d'Acoz et al, 2005;Worsfold & Ashelby, 2006).…”

First description of heavy skeletal deformations in Palaemon shrimp populations of European estuaries: the case of the Gironde (France)

This study aims at analyzing morphological deformities in Palaemon population in the Gironde estuary. The most frequent abnormalities affected cephalothorax and rostrum, and to a lesser extent scaphocerites and uropods (with spectacular dissymmetry), whilst only few cases of antenna and telson deformities were observed. References on morphological abnormalities of crustaceans can be found in the literature, but dealing with only isolated individuals and not for Palaemonids species, whilst in the Gironde estuary up to 40% of adult individuals are affected. Deformities likely depend on water pollutants, among others heavy metals and PCBs. This hypothesis should be tested considering other European estuaries with similar features.

High genetic diversity and absence of founder effects in a worldwide aquatic invader

The introduced oriental shrimp Palaemon macrodactylus has recently become widespread in temperate estuaries worldwide. However, this recent worldwide spread outside of its native range arises after a previous introduction to the US Pacific coast, where it was restricted for more than 30 years. Using a phylogeographic approach, the present work investigates the genetic history of the invasion of this decapod worldwide. Japan acted as the main native source area for worldwide introduced populations, but other native areas (likely South Korea and China) may act as source populations as well. The recently introduced European and NW Atlantic populations result from colonization from both Japan and an unknown area of the native range, although colonization from the NE Pacific could not be ruled out. Most introduced populations had higher haplotypic diversity than most native populations. P. macrodactylus has a strong potential to become one of the most widespread introduced species and may become the dominant estuarine shrimp in Europe. The ecological and economic consequences of this invasion remain to be thoroughly evaluated.

“…The low stream velocity of the canal Ghent-Terneuzen could have favoured the upstream migration of P. macrodactylus. Monitoring of the Thames showed that P. macrodactylus was possible to co-occur with the indigenous P. longirostris in British estuaries, potentially occupying overlapping ecological niches (Worsfold & Ashelby, 2006). Despite the co-occurrence of P. macrodactylus with other carrideans, a dietary overlap is possible with species of the same size sharing similar resources.…”

Using long-term monitoring to investigate the changes in species composition in the harbour of Ghent (Belgium)

The macroinvertebrate community of the harbour of Ghent was studied by analysing 135 samples taken at different sampling locations from 1990 until 2008. The results showed that the current Crustacea and Mollusca communities are mainly represented, in terms of abundances, by alien species. In total, seven alien and four indigenous crustacean species were found. Mollusc diversity was higher, with a total of 14 species, four of which were alien. Macroinvertebrate diversity was very low at the beginning of the 1990s, but increased due to the improvement of the chemical water quality achieved by sanitation and stricter environmental laws. This is reflected by the dissolved oxygen concentration, which increased from an average of 2 mg/l to an average of 9 mg/l, allowing more sensitive species to establish. Since 1993, the number of alien taxa has augmented, whereas the number of native taxa has remained stable. The improvement of the chemical water quality and the simultaneous increase in total number of species were also reflected in an increase of the Multimetric Macroinvertebrate Index Flanders, which is used to assess the ecological water quality in Flanders. Due to intensive international boat traffic and the low species diversity, the harbour of Ghent is highly vulnerable for invasions. Stronger regulations and a better understanding about the contribution of shipping, shortcuts via artificial water ways, habitat degradation and environmental pollution are required to reduce the further spread of alien species
