The introduction of aquatic species that led to invasive spread may have started with the carp Cyprinus carpio. Carp is thought to be two subspecies of her that are documented to have lived in Europe and Asia over 10,000 years ago and then domesticated independently. Recent genetic evidence confirms the existence of his two subspecies of carp. Domestication involves the movement of animals, so the initial spread of the invasive carp can be attributed to the Romans, who brought it into Europe from the Danube. Today the carp is one of the world's most important invasive aquatic animals. More than 3.5 million tonnes of carp are produced in aquaculture each year (Aquaculture Bureau Statistical Information Service, 2012) and used as human food. However, the damage to global ecosystems from carp invasions points to the problem of introducing alien species, efforts to mitigate the negative impacts of invasions, and the length of time invasive aquatic species remain a nuisance. Considerations regarding the intentional introduction of exotic aquatic animals are explored to balance the consequences and benefits of introduction. In particular, tilapia, Chinese carp and ornamental fish are important commercial fish with a reputation for being invasive to aquatic ecosystems. Over the course of human history, over 50,000 of his alien species, including many aquatic animals, have been brought to North America. Some of these species, such as wheat, rice, cattle, and poultry, were introduced as food sources and now provide more than 98% of the US food system worth about $800 billion annually. Robotic systems are becoming more and more popular, whether on land, in the air, or in water. In water, underwater drones such as ROVs (Remotely Operated Vehicles) and AUVs (Autonomous Underwater Vehicles) have opened up new possibilities for studying ocean depths. However, these technologies have limitations regarding on-board support, programming, and functionality in complex marine environments. These drones are based on animal designs and abilities. Biological AUVs (BAUVs) promise improved performance in diverse marine environments. Comparing animal swimming performance with conventional AUVs and BAUVs shows that natural systems still have swimming capabilities that exceed current AUV technology. However, aquatic animal performance in terms of swimming speed, efficiency, maneuverability and camouflage will serve as a benchmark to guide the development of his bio-inspired AUV technology with enhanced capabilities. Aquatic species can absorb dissolved minerals from water through their gills, oral epithelium (and other membranes), and water intake. Fish and crustaceans can absorb minerals by routes other than digestion of food, ingest seawater, and exchange them from the aquatic environment through skin and gill membranes. Most of the calcium we need comes from water. For marine animals, water provides the majority of iron, magnesium, cobalt, potassium, sodium and zinc. Aquatic species are the main source of omega-3 fatty acids. Omega-3 fatty acids are synthesized primarily in algae and phytoplankton and are transferred through food webs to fish and marine mammals. The Aquatic Species Program (ASP) is one of the glorious algae biofuel projects initiated in 1978 by the U.S. Mussels filter water in aquatic ecosystems, keeping it clear and removing silt and contaminants. Migratory aquatic animals require multiple types of habitat throughout the year.
