Eel grass
Eel grass Many research have centered at the distribution and effect of this invasive species. Generally, intertidal Z. japonica competes with indigenous seagrasses most effective to a restricted extent, and accordingly its invasion has minimum bad effect at the nearby ecosystem (Williams, .
Despite the creation of Z. japonica to the North American Pacific Coast and its endured enlargement, the seagrass in its authentic habitats (i.e., temperate and subtropical regions of the western Pacific Coast) has gone through intense decline Abe et al.
However, withinside the intertidal sector of Swan Lake in Rongcheng, Z. japonica is broadly dispensed or even paperwork an in depth seagrass mattress. Z.
aponica at the east coast of Swan Lake started out to unfold in Before then, such an enlargement had by no means been visible on this location.
Influence of Habitat Structure Eel grass
Sediment-primarily based totally substrates, which include dust or eelgrass, do now no longer drastically guard refuge-restrained segment juveniles from both fish or crab predators (Roach, 1983; Barshaw and Lavalli,
With untethered lobsters and longer intervals withinside the discipline, the wide variety of animals ultimate in a place appears to be lower. The percent of emergent segment lobsters (levels XI–XV; 50- to 90-mm TL)
ultimate on a substrate of blocks on sand after eleven days ranged from eight to 25.five% (Kittaka et al., 1983). If the blocks had been positioned close to habitats wherein fishes had been extra abundant, most effective 2.7% of the stocked lobsters remained.

III. North Atlantic (North Carolina to Portugal)
Seagrasses withinside the temperate Atlantic are ruled via way of means of Zostera marina (eelgrass). Eelgrass is determined in maximum shallow coastal gentle backside environments with moderately excessive water clarity.
It flourishes in a large variety of environmental situations from coarse sand and gravel on uncovered coast to first-class grained gentle muds in quiescent eel2. backwaters. Eel grass
