Kluwer Academic Publishers, Dordrecht, Boston, London: 104-115 Comments: Species of the Ponto-Caspian complex, such as Chelicorophium curvispinum, Chaetogammarus ischnus, Pontogammarus robustoides, Dikerogammarus haemobaphes, D. villosus, Dreissena polymorpha, and Litoglyphus naticoides are found only in freshwaters or in oligohaline lagoons, like Vistula Lagoon (salinity 3-5 PSU) or Szczecin Lagoon (0.5-1.5 PSU). |
Habitat modifying ability potential (?) | Keystone species Comments: P. robustoides is a large, competitive and aggressive amphipod species – it is known to predate on other organisms (Oligochaeta, Chironomidae etc., exact data are not available). Thus is may pose a threat to local benthic fauna, including native amphipods (e.g. Gammarus lacustris in freshwaters). |
Toxicity / Life stage (?) | Not relevant |
Bioaccumulation association (?) | Unknown Comments: Not available. |
Known human health impact? | Known References: U.S. Fish and Wildlife Service, 2015. Ecological Risk Screening Summary: Pontogammarus robustoides (amphipod). [pdf] Available at: https://www.fws.gov/sites/default/files/documents/Ecological-Risk-Screening-Summary-Pontogammarus-robustoides-amphipod.pdf [Accessed 19 July 2024]. Comments: Species does not pose any threat to human health since it is not known to be a vector of any human pathogens. |
Known economic impact? | Known References: Grudule, N., Parele, E., Arbaciauskas, K. 2007. Distribution of Ponto-Caspian amphipod Pontogammarus robustoides in Latvian waters. Acta Zoologica Lituanica, 17(1), pp. 28-32. Comments: P. robustoides was noted in food chains of local and introduced fish. Investigation of fish nutrition in Keguma water reservoir during 1971-1972 showed that P. robustoides accounted for 36-48% of perch diet during certain periods. |
Known measurable environmental impact? | Known References: Arbačiauskas, K., Gumuliauskaitė, S. 2007. Invasion of the Baltic Sea basin by the Ponto-Caspian amphipod Pontogammarus robustoides and its ecological impact. In Biological invaders in inland waters: profiles, distribution, and threats, pp. 463-477. Comments: In habitats where P. robustoides is well established and numerous, it significantly reduces species richness and community diversity. Moderate pontogammarid density in habitats that can sustain the native gammarid Gammarus lacustris, however, revealed no negative impact on diversity metrics. |
Included in the Target Species list? | No References: HELCOM, 2009. Alien Species and Ballast Water [PDF]. Available at: (https://archive.iwlearn.net/helcom.fi/stc/files/shipping/Table_2_Alienspecies_%20lists_2009.pdf) |
Association with vessel vectors (?) | Ballast waters References: Arbačiauskas, K., Gumuliauskaitė, S. 2007. Invasion of the Baltic Sea basin by the Ponto-Caspian amphipod Pontogammarus robustoides and its ecological impact. In Biological invaders in inland waters: profiles, distribution, and threats, pp. 463-477. Comments: Within the Baltic Sea, P. robustoides can be transferred not only in ballast waters but also in the hull fouling of ships, especially over short distances by slow-speed vessels, such a dispersal method being possibly the most import-ant. |
