The introduction of aquatic species leading 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. I'm here. Aquatic species can absorb dissolved minerals from water through their gills, oral epithelium (and other membranes), and water intake. , seawater can be ingested and exchanged from the aquatic environment through the membranes of the skin and gills. Dietary mineral requirements are influenced by water chemistry. 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. Oily fish meats (mackerel, tuna, herring, sardines, menhaden, salmon), lean fish livers (cod and halibut), and marine mammal fats (seal and whale) are major sources of omega-3 fatty acids, especially EPA. Crustaceans, mussels and cephalopods are also good sources of omega-3 fatty acids. The Aquatic Species Program (ASP) is one of the glorious algae biofuel projects initiated in 1978 by the U.S. Department of Energy's Office of Fuel Development to develop renewable fuels for transportation from algae. The program initially focused (until 1982) on bio hydrogen production, but then shifted to screening potential species for biodiesel production from microalgae. Due to budget cuts, the program was terminated in 1996. The aim of this project was not only to find species of microalgae, but also to define production strategies, including cultivation systems such as open ponds and his PBR. Many aquatic organisms benefit from production on land and vice versa. In addition to leaves, large amounts of fruits, flowers, seeds, insects, and droppings fall from the canopy into the stream, providing an important source of energy and nutrition for the biota. Terrestrial invertebrates make up the majority of the gut contents of most fish species in the streams of the low-order Amazon rainforest. Globally, aquatic organisms of all kinds are among the most endangered species due to pollution and habitat loss. This has drawn attention to the need to record aquatic habitat fauna and understand the habitat variables that have the greatest impact on species occurrence and distribution. Mayflies as a group are known to be sensitive to habitat disturbances and have been used worldwide to monitor changes in the quality of aquatic systems, but it is important to control species distribution and their occurrence. Our knowledge of what does is still incomplete in many regions. Intensive research has been carried out in many regions of the world to build databases from which to derive conservation strategies.
