AquaNISInformation system on aquatic non-indigenous and cryptogenic species |
Species | Gracilaria vermiculophylla | |
Date of the first record (?) | To 1998 References: Thomsen, M. S., Gurgel, C. F. D., Fredericq, S., & McGlathery, K. J. (2006). GRACILARIA VERMICULOPHYLLA (RHODOPHYTA, GRACILARIALES) IN HOG ISLAND BAY, VIRGINIA: A CRYPTIC ALIEN AND INVASIVE MACROALGA AND TAXONOMIC CORRECTION 1. Journal of phycology, 42(1), 139-141. Comments: This confirmed that the cylindrical Gracilaria that dominates Hog Island Bay is indeed G. vermiculophylla, and that all samples from the northern Atlantic analyzed so far present no genetic differences with regard to cox2–cox3 spacer DNA sequences (Thomsen et al, 2006). |
Recipient region (?) | Country: USA LME: 7. Northeast U.S. Continental Shelf LME sub-region: Mid-Atlantic Bight References: Thomsen, M. S., Gurgel, C. F. D., Fredericq, S., & McGlathery, K. J. (2006). GRACILARIA VERMICULOPHYLLA (RHODOPHYTA, GRACILARIALES) IN HOG ISLAND BAY, VIRGINIA: A CRYPTIC ALIEN AND INVASIVE MACROALGA AND TAXONOMIC CORRECTION 1. Journal of phycology, 42(1), 139-141. |

Pathway / Vector (?) | Level of certainty: Possible Pathway: Culture activities Vector: Intercontinental stock movement References: Thomsen, M. S., Gurgel, C. F. D., Fredericq, S., & McGlathery, K. J. (2006). GRACILARIA VERMICULOPHYLLA (RHODOPHYTA, GRACILARIALES) IN HOG ISLAND BAY, VIRGINIA: A CRYPTIC ALIEN AND INVASIVE MACROALGA AND TAXONOMIC CORRECTION 1. Journal of phycology, 42(1), 139-141. Comments: "Gracilaria vermiculophylla probably arrived in Virginia attached to transplanted oysters, because it is an efficient recruiter onto bivalve shells and man-made structures, and has a high ability to recover from fragmentation". Thomsen et al, 2006. |

Comments: "Hog Island Bay is a turbid shallow lagoon, where G. vermiculophylla represents >80% of the submerged macrophyte biomass" (Thomsen et al, 2006). |
