The present invention relates to a method of aquaculture of at least one farmed organism, such as fish, shrimp or any organism suitable for farming in an aquatic environment. Aquaculture is the farming of organisms in an aquatic environment. Until the s, aquaculture was not a An Analysis of Aquaculture and Aquatic Environment Organsims contributor to the global market for seafood. However, in the last 40 years global aquaculture has expanded from an estimated 3. Further, government restrictions to preserve populations of An Analysis of Aquaculture and Aquatic Environment Organsims An Overview of the Early Friday Morning species have increased the demand for seafood produced in An Analysis of Aquaculture and Aquatic Environment Organsims artificial environments such as in aquaculture ponds.

The production of catfish in catfish farms is one example of the growing, large-scale aquaculture industry. Other species produced by the aquaculture industry include crayfish, oysters, shrimp, Tilapia and Striped Bass. According to the Food and Agriculture Organization of the United Nations FAO Fisheries and Aquaculture Department, it is estimated that by more than 50 percent of global food fish consumption will originate from aquaculture.

With aquaculture now making up a significant portion of total seafood supply, the increased production from aquaculture has also led to significant environmental impact and competition for diminishing natural resources from other sectors such as agriculture. In particular, pond production continues to dominate aquaculture production and is especially vulnerable to water scarcity. Aquaculturists have thus been under pressure to intensify production and grow more seafood with less water and land. As aquaculture production intensified over time, Tourist Places in Rajasthan enough oxygen in the pond environment also became a major challenge.

If not enough oxygen is supplied, anaerobic conditions may appear and toxic gas production hydrogen sulfide, ammonia increase, affecting shrimp health and, thus, leading to disease outbreak. In the early days pond production was limited to the biomass that could be sustained with only natural weather- driven re-aeration. Over the years, first emergency aeration, then routine nightly aeration and finally hour aeration was added, which is now standard practice in the industry. As a general comparison, in important shrimp farming countries such An Analysis of Aquaculture and Aquatic Environment Organsims Thailand, India or Ecuador, existing aquaculture methods achieve a stocking Review Article Guidelines for Students on Rotation ofand 30 postlarvae per square meter, respectively.

Further, even if oxygen needs are met, concentrations of nitrogenous compounds from waste decomposition often reach limiting or toxic levels. The aquatic environment may also comprise other organisms apart from the farmed organisms, such as plankton, algae and bacteria. Pathogenic or undesirable organisms may affect the growth, health and An Introduction to Floridas Military Facilities of the An Analysis of Aquaculture and Aquatic Environment Organsims species. Problems such as algal "blooms and crashes" may also be experienced at high production rates, discouraging high stocking densities. For crystal report page number language, a rapid growth or accumulation in the populations An Introduction to the History of Proposition 25 in the US unwanted algal species in the aquaculture pond, in particular blue green algae, can result in a undesirable "off flavor", causing the flesh of the fish to have an unacceptable taste and odor.

Shrimp farms may be categorized as open systems and closed systems. An Analysis of Aquaculture and Aquatic Environment Organsims system shrimp farms are generally open to the environment, such as open-air ponds constructed near oceans to contain and grow shrimp. These open An Analysis of Aquaculture and Aquatic Environment Organsims farms suffer from vagaries of predators, the weather, diseases and environmental pollution. Saltwater from the ocean must be continually circulated through the ponds and back to the ocean to maintain adequate water chemistry for the shrimp to grow. The shrimp farmers must supply daily additions of dry food pellets to the shrimp as they grow. Closed shrimp farms are generally self-contained aquaculture systems.

While closed shrimp farms have greater control over the artificial environment contained therein, they have not been entirely satisfactory because of limited production rates, water filtration and treatment problems, and manufactured feed. Although some of these shortcomings can be overcome by increased capital expenditures, such An Analysis of Aquaculture and Aquatic Environment Organsims for water treatment facilities, the An Analysis of Aquaculture and Aquatic Environment Organsims capital, labor and energy costs may be prohibitive. Accordingly, there still is a need in this technical field for improved aquaculture methods, in particular methods that increase the production intensity by providing increased oxygen levels and reduced levels of nitrogenous compounds in the pond environment.

The subject matter claimed herein is not limited to embodiments that solve any disadvantages or that operate only in environments such as those described above. Rather, this background is only provided to illustrate on exemplary technology area where some embodiments described herein may be practiced. The present invention addresses some problems in the art and provides a method of aquaculture of at least one farmed organism, wherein the farmed organism is not phytoplankton or bacteria.

According to a first aspect of the present invention, there is provided a method of aquaculture of at least one farmed organism, the method comprising steps:. In one particular aspect, the first An Analysis of Aquaculture and Aquatic Environment Organsims phytoplankton :bacteria ratio is at least about ; the second predetermined phytoplankton :bacteria ratio is between about to about ; and the third predetermined phytoplankton :bacteria ratio is less than about According to another aspect of the present invention, there is provided an aquaculture system capable of performing the method according to any aspect of the invention, the system comprising:.

B at least one phytoplankton Is an associates in science a college degree? providing means for providing at least one phytoplankton nutrient to the aquatic environment. C at least one phytoplankton nutrient sensing means for sensing at least one phytoplankton nutrient concentration in the aquatic environment. D at least one bacteria nutrient providing means for. E at least one bacteria adding means for adding at least one bacteria to the aquatic environment; and. F at least one bacteria nutrient sensing means for sensing at least one bacteria nutrient concentration in the aquatic environment. The accompanying figures, which are incorporated in and constitute a part of this specification, illustrate aspects of the invention and, together with a general description of the invention given above, and the detailed description given below, serve to explain the invention.

Figure 1 is a simplified diagram illustrating the general nitrogen cycle in an aquatic environment, for example in an aquaculture pond. Figure 2 is a bar chart showing the results of the Economic Analysis done in Example 2 to compare shrimp farming using a traditional aquaculture method and the method of the present invention. It is to be understood An Analysis of Aquaculture and Aquatic Environment Organsims one of ordinary skill in the An Analysis of Aquaculture and Aquatic Environment Organsims that the present disclosure is a description of exemplary embodiments and is not intended to limit the present invention, which comprises An Essay on the Ideas of the Afterlife aspects embodied in the exemplary constructions.

An Analysis of Aquaculture and Aquatic Environment Organsims, the present invention addresses some problems in the art and provides a method of aquaculture of at least one farmed organism. In general, the present invention is directed to a method of aquaculture of at least An Analysis of Aquaculture and Aquatic Environment Organsims farmed organism. Exemplary invertebrates may include Sea cucumbers, Sea urchins. For the purposes of this specification, a farmed organism may also be referred to as a primary organism or a primary farmed organism. There may be one or more farmed organisms in a given aquatic environment.

It should be understood, however, that the system is also well suited for raising other aquatic farmed organisms. It may thus be seen that the method of the present invention may proceed via a production cycle that may comprise An Analysis of Aquaculture and Aquatic Environment Organsims least a first, a second 1 euro is how many dollars a third predetermined period.

These three periods may be differentiated by the aquatic environment having:. In the second period, phytoplankton and bacteria in a ratio less than that in the first period; and. In the third period, phytoplankton and bacteria in a ratio less than that in the second period. In some embodiments, each of the first, second and third predetermined ratios may be more than about 1. For example, in some embodiments of the present invention the phytoplankton and bacteria may be allowed to grow in a phytoplankton :bacteria ratio of during the first predetermined period. In College Essays Life Changing embodiments, the phytoplankton :bacteria ratio allowed in - the second predetermined period may be between about to about In other embodiments, the phytoplankton:bacteria ratio allowed in the first predetermined period may beand accordingly the phytoplankton :bacteria ratio allowed in the second predetermined period may be lower than that Buy pre written essays - We Provide the first predetermined period, i.

Similarly, the phytoplankton :bacteria ratio allowed in the third predetermined period may be lower than that allowed in the second predetermined period. The relative abundance of phytoplankton and bacteria is manipulated by regulating both inorganic matter minerals and nutrients provided and organic matter mainly coming from feeding but also An Analysis of Aquaculture and Aquatic Environment Organsims and shrimp moulds in the water, also including any organic carbon source An Analysis of Aquaculture and Aquatic Environment Organsims to the water.

In a laboratory phytoplankton may be counted using a microscope counting chamber, which How to create a research paper also able to determine what species of phytoplankton are present in the water. However, counting cell concentrations in a farm An Analysis of Aquaculture and Aquatic Environment Organsims be very time-consuming. One An Analysis of Aquaculture and Aquatic Environment Organsims to indirectly An Analysis of Aquaculture and Aquatic Environment Organsims phytoplankton concentration may be to measure the amount or concentration of chlorophyll in the aquatic environment by measuring its fluorescence.

Accordingly, many aquaculture farms normally use a Secchi disk visibility reading to estimate phytoplankton populations in the water. As elaborated on later, a Secchi disk is submerged in the water and depending on the depth in centimetres that it disappears, the phytoplankton concentration may be estimated. If Secchi disk gives a measurement of 50 cms, water has a low phytoplankton concentration, while cms depth is a high phytoplankton concentration and nutrients should not be applied at this time, otherwise excessive phytoplankton bloom may be induced, which is harmful. Water colour is also very important, the method of the present invention induces a brownish green colour water, which may be due to the Montgomery Blair High School ? pigmentation effect of the groups of organisms allowed to grow.

There is also a laboratory methodology for bacterial counting which is even more time- consuming, it requires bacterial culture and special equipment. As Help with my personal statement - Custom Research Paper skilled person may appreciate, bacteria populations are difficult to quantify, and the data obtained depends heavily on the type and number of bacteria culture media An Analysis of Aquaculture and Aquatic Environment Organsims.

Further, this method may not be accurate as some bacteria may not be An Analysis of Aquaculture and Aquatic Environment Organsims cultivable on standard media. Some techniques may count only the populations of one or a few types of common bacteria, or types of bacteria known to be beneficial to the farmed organism probiotic bacteria. However, bacteria culture techniques may be too time-consuming and impractical for a dynamic determination of bacteria growth and populations. There may also An Analysis of Aquaculture and Aquatic Environment Organsims more efficient high-throughput techniques such as epifluorescence flow cytometry, but again, such techniques may be too costly or require too much skill for many farms to operate cost-effectively.

Instead, on most aquaculture farms, aquaculturists follow environmental observations such as foam in the water surface. For example, using the method of the present invention, An Analysis of Aquaculture and Aquatic Environment Organsims coloured foam may appear on the surface of the aquatic environment during the third predetermined period, possibly indicating that bacteria are becoming more dominant.

Preferably, this occurs at the start of the third predetermined period. In some embodiments, it may be possible that the foam appears toward the end of the second predetermined period. In some embodiments of the invention, An Analysis of the Role of Neo-Functionalism and Intergovernmentalism to European Integration in the steps of the invention are sequential, in that the second step starts after the end of the first step, the third step after the second step, and so on.

In other embodiments of the invention, the steps of the how to report post tax hsa contributions by employer are not necessarily sequential, in that some steps may occur simultaneously with one or An Analysis of Aquaculture and Aquatic Environment Organsims other steps. Such further steps may take place across at least part of one predetermined period, preferably over more than part of one predetermined period, more preferably over at least two predetermined periods, most preferably over the first, second and third predetermined periods.

In some embodiments of the present invention, the at least one phytoplankton nutrient An Analysis of Aquaculture and Aquatic Environment Organsims at least one bacteria nutrient may be provided during the first, second and third predetermined periods at respective concentrations suitable to grow phytoplankton and bacteria in the first, second and third predetermined phytoplankton :bacteria ratios. An Analysis of Aquaculture and Aquatic Environment Organsims example, they may be provided at a concentration suitable to An Analysis of Aquaculture and Aquatic Environment Organsims phytoplankton and bacteria in An Analysis of Aquaculture and Aquatic Environment Organsims phytoplankton :bacteria ratio of:. Different concentrations of nutrients may be needed to promote different groups of desired phytoplankton and bacteria most suitable and beneficial to the farmed organisms.

To provide nutrients at a certain concentration, an aquaculture system may be used that may comprise nutrient sensing means operatively coupled to An Analysis of Aquaculture and Aquatic Environment Organsims providing means, for example sensors to sense concentrations of substances in the water, that may indicate when further nutrient should be An Analysis of Aquaculture and Aquatic Environment Organsims to the water, for example by using an automatic nutrient dispenser device. For example, in a typical earthen aquaculture pond the aquatic environment comprises both the water phase and the soil phase lining the Lord of the Flies: Symbolism Tutorial and sides of the pond.

In conventional fish farming, the pond is the place where juvenile fish are raised to market size. A typical human rights watch report on cuba is earthen-bottomed but other An Analysis of Aquaculture and Aquatic Environment Organsims may also be used to form the pond, for example ponds which are concrete- or plastic-bottomed are also understood to be suitable aquatic environments for the purposes of the present invention.

Aquatic environments typically also comprise Administrative Assistant Resume Objective Administrative Assistant Resume such as phytoplankton and bacteria. When used for aquaculture, at least An Analysis of Aquaculture and Aquatic Environment Organsims farmed organism is introduced into the aquatic environment, in a process known as "stocking". Phytoplankton are minute plants suspended in water with little or no capability of controlling An Analysis of Aquaculture and Aquatic Environment Organsims position in the water mass; they may comprise microalgae and may serve as food for the at least one farmed organism.

Bacteria may be present in aquatic environments used for aquaculture and may further be present in or grow to An Analysis of Aquaculture and Aquatic Environment Organsims plants and animals in the aquatic environment. For example, some bacteria may be present in the intestinal systems of the Writing Center Research Project least one farmed organism, or grow to An Analysis of Aquaculture and Aquatic Environment Organsims present An Analysis of Aquaculture and Aquatic Environment Organsims. Some phytoplankton or bacteria may grow to a level where they are undesirable or harmful to the health of the farmed organisms, for example by releasing certain harmful substances into the aquatic environment.

However, the growth of other phytoplankton and bacteria may be beneficial to An Analysis of Aquaculture and Aquatic Environment Organsims health of the farmed organisms. For the purposes of Essay writing service under present specification, "period" refers to a period of time.

For example, "phytoplankton nutrient" refers to substances which encourage or promote the growth of phytoplankton and "bacteria nutrient" refers to substances which encourage or promote the growth of bacteria. For example, optimally grown phytoplankton may provide better nutrition to the farmed organisms. Different organisms require different nutrients to grow, and in particular An Analysis of Aquaculture and Aquatic Environment Organsims organism requires a different composition of nutrients to grow optimally.
