uses of aquatic animals

Animals are widely used for transport. Living as an aquatic animal in temporary waters means having to cope with, or circumvent, the harsh conditions of the dry season. Potable water comprises only a small fraction of the total use of water in the United States, with the main uses of freshwater resources being agricultural (for example, irrigation, animal feeding operations) and industrial (for example, cooling towers) activities 1. Aquatic animals may breathe air or extract oxygen that dissolved in water through specialised organs called gills, or directly through the skin. Crocothemis erythraea, not a temporary water specialist, needed 49 days in temporary ponds (Suhling et al., 2004). Plants and animals in an aquatic ecosystem show a wide variety of adaptations which may involve life cycle, physiological, structural and behavioural adaptations. Only about 2000 of the known aquatic animal species are used in some form of managed system. Freshwater habitats are aquatic habitats with low levels of salt, less than one percent. Ampullariidae). For this, animals like horses, ox, he-buffalo, donkeys, etc. In addition, aquatic birds and some reptiles (such as aquatic snakes) prey upon the adults. They eat particles up to 10 μm in size. Also some Libellulidae, such as the Oriental Potamarcha congener Rambur, 1842, survive the dry season in the egg stage; the development is triggered by low oxygen content when the pond is refilled with water (Miller, 1992). Funding for research on the genetics of aquatic animals has not received high priority. Other aquatic plants include watercress, water chestnuts, and various other edible species. Unlike nonmarine aquatic animals, most marine macrobenthic animals produce planktonic larvae, some of which feed on plankton before settling (Levinton, 1982). Many habitats are at risk which puts aquatic animals at risk as well. Wetlands are among the most productive ecosystems in the world, comparable to rain forests and coral reefs. In deserts, camel is specifically used. Interestingly, dry-season survival of the aquatic stages appears to be uncommon in species living in arid regions; most of these species develop directly and require open water. That is also largely the function of the different aquaculture systems—to manage the animals’ environment. Major advantages of the use of aquatic animals, such as trout, English sole, or sea urchins, for studying the mechanisms of reproductive toxicology are discussed. Sphaeriids, however, are very mobile and mature quickly giving birth to small clams that must be in well-oxygenated sediments for best survival (Burch, 1972). Water beetles and water living mammals can carry algae from one pond to a nearby one; dragonflies may be more effective transporters and waterfowl are of prior importance. The OIE Aquatic Animal Health Code (the Aquatic Code) provides standards for the improvement of aquatic animal health worldwide.It also includes standards for the welfare of farmed fish and use of antimicrobial agents in aquatic animals. Due to the dependence of amphibians on water and warmer temperatures, they are most active in the summer and often hibernate on land in the winter. Most rotifers are around 0.1–0.5 mm long, although their size can range from 50 μm to more than 2 mm (Howey, 1999). Typically, these are long concrete or masonry channels with significant drops in height and very thin layers of water, making aquatic animal passage almost impossible (Larinier, 2000). An aquatic animal is an animal, either vertebrate or invertebrate, which lives in the water for most or all of its lifetime. They include rivers, lakes, streams, ponds, swamps, wetlands, bogs and lagoons. Although most nations have developed organizations to administer their common property, overlapping jurisdictions often limit agencies’ abilities to satisfy their mandates.

Such powers which help some aquatic species to survive in challenging conditions like deep ocean. The term aquatic can be applied to animals that live in either fresh water animals]]) or salt water (marine animals). Aquatic animals and their adaptational characteristics. Management and conservation of the genetic resources of aquatic animals should encompass a greater number of species. Most SFRB that have been designed with a small fish pass or bypass stream would score between 41% and 69%. Consequently specialists in the genetics of aquatic species are scarce. The main trait seems to be rapid development that allows them to emerge before the habitat dries out (Johansson and Suhling, 2004). There is a food chain within every aquatic ecosystem. Planorbidae) and some amphibious ones have both (e.g. Larvae of the Australian aeshnid Telephlebia brevicauda Tillyard, 1916, hide in wet detritus. Species that reproduce in temporary waters need specific strategies to survive. Fins and gills are the locomotors and respiratory organs respectively. A few environmental variables are fundamental and a discussion of the ways that aquaculture systems control them is the unifying theme of this chapter, how the specific system being examined provides the cultured animal with the, (1) proper temperature for growth, (2) sufficient oxygen to breathe, (3) removes the inevitable waste products and in some cases, (4) provides some or all of the animals’ food needs. The temporary pond specialist P. flavescens completed larval development in Namib Desert ponds in 38 days; it is probably able to make it in 30 days. Transport via the digestive parts of birds may be more efficient because desiccation is ruled out. Aquatic Animals Topics. Actually porpoises and dolphins have 40 species. This endeavour must be supplemented by efforts to understand the basic biology, genetics, demographics, and ecology of aquatic animal species. J. Padisák, in Encyclopedia of Inland Waters, 2009.
