Marine Crustacea

As far as the environment is concerned the main factor is to remove solid particles by settling and filtration and to remove marine Crustacea by screening. 

Marine Crustacea, which include barnacles and crabs and the marine molluscs, which include mussels, can cause severe fouling problems when coastal seawater is used for once-through cooling of power plant turbine condensers. Various species of marine barnacles, mussels, and their spat quickly establish in warm waters and become extremely troublesome. (The problems are exacerbated by seaweed, sponges, various other marine organisms, and SRBs.) The marine acorn (or rock) barnacle, of group Cirripedia, is a common marine foulant, as are the mussels of family Mytillidae.

Figure 22.11. Cellulose is a structural and rather chemically inert component of terrestrial plants. Alginic acid is synthesized by marine algae and has medicinal properties. Some polysaccharides contain nitrogen in the form of amino sugars. The primary example of this is chitin, which composes the exoskeletons of Crustacea. An amino sugar contains an amine in place of a hydroxyl group. In other polysaccharides, sugars combine with lipids and proteins. These form glycoUpids and glycoproteins, respectively.

Aqueous and sedimentary TBT and TFT cause chronic and acute effects in algae, zooplankton, Crustacea, mollusks, fish, and animals. These effects have been local in nature, occurring mostly in harbors near industrialized lands. TBT is bioaccumulated in many species, which is unfortunate as it is a potent endocrine disrupter. The enrichment factor in mussels, snails, and oysters ranges from 10,000 to 60,000. As mentioned in Section 28.7.1, TBT induces imposex in marine gastropods.

In several fish species and one marine crustacean, taurine conjugates of xenobiotic carboxylic acids have been Isolated from urine (fish) or hepatopancreas (Crustacea) and subjected to unequivocal chemical characterization (77-82). Table VIZ shows which acids are conjugated with taurine in some marine species.
