Dissertation, Université Laval; Drouin A, McKindsey CW, Johnson LE. The characteristics of reproduction in 2 New York populations of Codium fragile were investigated over nearly a 2‐yr period. Description: A spongy, dichotomously branched green alga without distinct flattening at the forks of the branches.
Higher abundance and diversity in faunal assemblages with the invasion of Codium fragile ssp. Seasonal patterns of growth, reproduction, and productivity of Codium fragile spp. tomentosoides (van Goor) Silva were monitored at 3 locations in Rhode Island. Codium fragile (Suhr) Hariot. Comparison of these reproductive traits with reports for the invasive Codium, C. fragile ssp. tomentosoides, in the northern Adriatic Sea FABIO BULLERI1,2, MARIA GIOVANNA BRANCA1, MARCO ABBIATI1,2 AND LAURA AIROLDI1,2 1Centro Interdipartimentale di Ricerca per le Scienze Ambientali in Ravenna, Universita` di Bologna, Ravenna, Italy
Development of reproductive structures in the introduced green alga, Codium fragile ssp. Maximal growth occurred during the summer and was more significantly correlated with temperature than any other factor measured in this study. Codium fragile – and Codium vermilara–derived water-soluble sulfated arabinogalactans prevented coagulation, but they induced platelet aggregation (Ciancia et al., 2007). Also known as Codium fragile subsp. Reproduction occurred by the exclusive formation of reproductive cells that germinated and developed, asexually. There was no evidence at any time that the reproductive cells fused and thus functioned as gametes. fragile in eelgrass meadows.
tomentosoides, collected from the northwestern Atlantic coast suggested that 1) in localized areas, two subspecies or varieties may coexist, and 2) no functional male gametes were produced by C. fragile populations from this coastline. tomentosoides and Codium fragile subsp. fragile dans les herbiers marins aux îles de la Madeleine. For the last two decades, Codium species have been of public and scientific concern because of the invasive, bloom-forming nature of some of them.Codium fragile subspecies tomentosoides is the most invasive seaweed in the world, and it is believed to be native to Japan and was then unintentionally spread around the world. ''Codium fragile'', known commonly as green sea fingers, dead man's fingers, felty fingers, forked felt-alga, stag seaweed, sponge seaweed, green sponge, green fleece, and oyster thief, is an invasive species of seaweed in the family Codiaceae.

A number of subspecies have been described, some of which have been introduced in various parts of the world. It was observed that anticoagulant activity was higher in SP samples with higher sulfate content. Drouin A (2013) Établissement et impacts de la macroalgue non indigène Codium fragile ssp. atlanticum.
