Association with vessel vectors

Actual evidence of being found in samples in a particular vector from any world region.

Anchor and anchor chains. Organisms found on anchors, anchor chain or within attached sediments, including anchor chain lockers.

Ballast water. Ballast water means water with its suspended matter taken on board a ship to control trim, list, draught, stability or stresses of the ship.

Biofouling. Biofouling means the accumulation of aquatic organisms such as micro-organisms, plants, and animals on surfaces and structures immersed in or exposed to the aquatic environment. Biofouling can include microfouling and macrofouling.

  • Macrofouling means large, distinct multicellular organisms visible to the human eye such as barnacles, tubeworms, or fronds of algae.
  • Microfouling means microscopic organisms including bacteria and diatoms and the slimy substances that they produce.
Biofouling comprised of only microfouling is commonly referred to as a slime layer.

Sub-species level

A geographical subset of a species showing discrete differences in morphology, coloration or other features when compared with other members of the species.

Comments:
The reproductive output of H. sanguineus is important: mature females may have 3-4 clutches per breeding season, with a mean clutch size of 15,000 and a maximum of at least 40,000-50,000 eggs per crab.
Reproductive type (?) Sexual

Comments:
Thus, the cycle from oviposition to
metamorphosis to the first crab may take about two months in the mid-Atlantic, more than a month of which involves the dispersal of larvae by tides and currents.

Comments:
The Asian shore crab, Hemigrapsus sanguineus (De Haan, 1853), is an opportunistic omnivore with well-developed predatory tendencies and a strong preference for animal food items over algae.

In laboratory experiments, 71 percent (319/448) of the crabs given a choice between macroalgae (Enteromorpha spp. and/or Chondrus crispus) and benthic invertebrates (Mytilus edulis and/or Semibalanus balanoides) consumed animals only.

In natural environment (saltmarshes), gut content analyses revealed the presence of marsh grasses and detritus in stomachs of H. sanguineus.

Comments:
Growth of bryozoans, mussels and barnacles on their carapaces.

H. sanguineus could play an important role in structuring the post-settlement
population dynamics of its invertebrate
prey, possibly leading to population declines of commercial shellfish.

When H. sanguineus occurs in high densities, this species can play an important role in restructuring the prey communities in intertidal habitats because they have the potential to affect
populations of native species such as crab, fish, and shellfish by disrupting the food web.
