Native origin (?) | Ocean: Pacific --> Ocean region: SW Pacific References (not structured): Paavola M., A. Olenin, E. Leppakoski 2005. Are invasive species most successful in habitats of low native species richness across European brackish water seas? Estuarine, Coastal and Shelf Science, 64: 738-750. |
Life form / Life stage (?) |
References (not structured): http://nas.er.usgs.gov/queries/factsheet.aspx?SpeciesID=1151, Accessed 29 June 2012 Comments: Branchiura sowerbyi are large, deep red, tubificid worms that are easily distinguished by the presence of dorsal and ventral gill pairs that cover the posterior quarter of the body. |
Sociability / Life stage (?) |
References (not structured): http://nas.er.usgs.gov/queries/factsheet.aspx?SpeciesID=1151, Accessed 29 June 2012 |
Reproductive frequency (?) | Iteroparous References (not structured): Raposeiro, P. M., Ramos, J. C., Costa, A. C. 2009. First record of Branchiura sowerbyi Beddard, 1892 (Oligochaeta: Tubificidae) in Azores. Aquatic Invasions, 4(3), pp. 487-490. |
Reproductive type (?) | Asexual Sexual References: http://nas.er.usgs.gov/queries/factsheet.aspx?SpeciesID=1151, Accessed 29 June 2012 Comments: Like other oligocheates, B. sowerbyi reproduces sexually via the clitellum and asexually through fragmentation. |
Developmental trait (?) | Brooding References: http://nas.er.usgs.gov/queries/factsheet.aspx?SpeciesID=1151, Accessed 29 June 2012 Comments: May reach sexual maturity within 4 months with a breeding peak in the summer months of June through July. B. sowerbyi may display a one to two year life cycle, dependent upon temperature, dissolved oxygen and substrate organic content. |
Characteristic feeding method / Life stage (?) |
References (not structured): http://nas.er.usgs.gov/queries/factsheet.aspx?SpeciesID=1151, Accessed 29 June 2012 Comments: These tubificid worms are benthic detritivores meaning that they live on the lake or river bottoms and feed from the decomposing organic matter in the sediment. |
Mobility / Life stage (?) |
References (not structured): http://nas.er.usgs.gov/queries/factsheet.aspx?SpeciesID=1151, Accessed 29 June 2012 Comments: As they feed, B. sowerbyi have been known to create intricate burrows up to 20 cm in depth. |
Salinity tolerance range (?) | Venice system: 1. Limnetic [<0.5psu] References: Paavola M, Olenin S, Leppäkoski E (2005) Are invasive species most successful in habitats of low native species richness across European brackish water seas? Estuarine, Coastal and Shelf Science 64 (2005) 738-750 |
Habitat modifying ability potential (?) | Allogenic ecosystem engineers References: Matisoff, G., Wang, X., McCal, P.L. 1999. Biological redistribution of lake sediments by tubificid oligochaetes: Branchiura sowerbyi and Limnodrilus hoffmeisteri/Tubifex tubifex. Journal of Great Lakes Research, 25(1), pp. 205-219. Comments: These worms feed head down in the sediment (up to 20 cm for B. sowerbyi and up to 10 cm for L. hoffmeisteri/T. tubifex) on organic-rich particles and deposit fecal pellets at the sediment-water interface (conveyor-belt feeding). |
Toxicity / Life stage (?) | Not relevant |
Bioaccumulation association (?) | Anthropogenic chemical compounds References: Piero, S .D, Masiero, L., Casellato, S. 2014. Toxicity and bioaccumulation of fluoride ion on Branchiura sowerbyi, Beddard, (Oligochaeta, Tubificidae). Zoosymposia, 9, pp. 44–50. Comments: B. sowerbyi is more resistant to fluoride than other freshwater invertebrates. |
Known human health impact? | Not entered |
Known economic impact? | Known References: Lobo, H., Espíndola, E. 2014. Branchiura sowerbyi Beddard, 1892 (Oligochaeta: Naididae) as a test species in ecotoxicology bioassays: a review. Zoosymposia, 9, pp. 59-69. Comments: B. sowerbyi is an oligochaete with great potential to be used as a test-species in toxicology bioassays. |
Known measurable environmental impact? | Known References: Ivicheva, K.N., Filonenko, I.V. 2023. First Record of Branchiura sowerbyi Beddard, 1892 (Oligochaeta) in the Sheksna Reservoir (Upper Volga). Russian Journal of Biological Invasions 14, pp. 151–154 . Comments: Owing to their large size and easy accessibility, B. sowerbyi can become a valuable food resource for fish. The danger of this species as a food object is manifested in the ability to be an intermediate host of myxospore parasites that cause swim bladder disease and hemorrhagic telochanellosis in fish. In this regard, the role.B. sowerbyi may have a negative impact on fisheries. |
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: Ivicheva, K.N., Filonenko, I.V. 2023. First Record of Branchiura sowerbyi Beddard, 1892 (Oligochaeta) in the Sheksna Reservoir (Upper Volga). Russian Journal of Biological Invasions 14, pp. 151–154 . Comments: Body. of B. sowerbyi was found in the area near the passage of ships. Probably, the path of penetration of this species into the Sheksna Reservoir is dissemination with ballast water along the Volga-Baltic waterway. |
