Aquaculture and Fisheries
Aquaculture is the breading, nurturing and reaping of fish, aquatic plants, algae, and other organisms. Aquaculture incorporates cultivating freshwater and saltwater inhabitants set up fish commercially in tanks or inclusions such as fish ponds under controlled conditions, fish farming are carp, tilapia, salmon, and catfish which is the reaping of wild fish. Mari culture refers to rearing and harvesting in aquaculture practiced in the all types of water, marine environments and in underwater habitats.

Aqua Farming- Techniques & Methods
Many techniques and methods are there for aqua forming. Farming of all categories of aquatic plants and animals may take place in the usual settings or tanks, in fresh water or sea water, in flow-through or re circulation systems, old-style or modern, classic or biological, shielded or visible, and so on. Aqua farming is essentially for home based or pond based small viable farm.

Livestock Production
Domesticated animals in household creatures rose to deliver work and wares. They likewise shape creature cultivation hones which have moved to creature cultivating. These practices increment the yield of different business yields. Animal’s generation fills in as the wellspring of wage. Aquaculture is viewed as having an imperative part to play in nourishing the developing populaces of many creating nations. Creature cultivation hones have changed generally crosswise over societies and eras. Initially, domesticated animals were not bound by wall or nooks, but rather these practices have to a great extent moved to concentrated creature cultivating, now and again alluded to as "processing plant cultivating".

Mari culture
Which are loaded with seawater? A case of the last is the cultivating of marine fish, including finish and shellfish like prawns, or clams and ocean growth in saltwater lakes. Non-sustenance items conveyed by Mari culture include: angle feast, supplement agar, adornments (e.g. refined pearls), and beauty upkeep products.

Nano Aquaculture
Nanotechnology in aquaculture industry is known as Nano Aquaculture. Nanoparticles will progress aqua feeds by grasping the percentage of animal food nutrients that pass across the gut tissue and into the animal, judiciously than passing directly through the animal digestive system unused. Dietary minerals at the Nano scale size may pass into cells more readily than their larger counterparts. This accelerates their assimilation process into the fish. Nanotechnology is advantageous in Disease Control and as a Protective Coating.

Aquaculture Biology
Aquatic Biology is a sub-discipline of biology it contracts with biology and ecology of organisms existing in freshwater systems such as streams and lakes to estuarine, coastal and open ocean ecosystems. Aquatic Biology is the science of living things involved with the fresh water ecosystems of our planet. Aquatic Biology is a Multidisciplinary forum for analysis on the biology of organisms in Marine, salt and contemporary waters.

Aquaculture Engineering
Aqua cultural engineering is a field of engineering that aims to solve technical problems associated with aquatic farming; aquaculture systems requiring optimization and engineering include sea cages, ponds and recirculating systems etc... The scheme and administration of these organizations is based on their production areas and the farming operations. Aquaculture engineering has played major role in the extension of the aquaculture industry, considerate the engineering behind aquatic production facilities is of increasing reputation for all those occupied in the industry.

Aquatic Pathology
Fish pathology contracts with the diseases and disease affecting agents that effects fish normal living. It studies fish defensive mechanism against diseases and its cure.

Aquaculture Nutrition
In world both developed and developing nations there has been tremendous growth in the farming of aquatic organism’s studies have showed that production can be increasing.

Aquatic Plants
Hydrophytes: hydrophytes are aquatic plants that are exclusively suitable for alive in aquatic Environments. A hydrophyte is also known as an aquatic macrophyte, either completely immersed in water or in some cases float on the shallow of the water. Aquatic plants necessitate special dissimilarities for living submerged in water, or at the water's surface. The most mutual variation is aerenchyma, but floating leaves and finely dissected leaves are also communal. Aquatic plants can only cultivate in water or in soil that is always saturated with water.

Fisheries Science
Fisheries science is the study and empathetic of fisheries. Fishing facts: Fishing is imperative to the world economy for all of these years, preliminary with the Viking trade of cod and then enduring with fisheries like those found in Lofoten, Europe, Italy, Portugal, Spain and India. Fisheries offer about 16% of the total world's protein with sophisticated percentages arising in developing nations. Fisheries are still extremely important to the economy and wellbeing of communities. The word fisheries science denotes to all of the fishing activities in the ocean they are to attain fish for the commercial fishing industries are for recreation or to obtain Ornamental fish or fish oil.

Marine Chemistry
Marine chemistry is the study of progressions of chemicals and composition of chemicals of the world’s oceans and it also deals with the chemical composition of the sea water it is consequently a special field of water chemistry and it also treaties with aspects of atmospheric chemistry, geochemistry, the biosphere and environmental chemistry Marine Chemistry is also recognized as Ocean chemistry, Marine chemistry inclined by Turbidity, currents, sediments, atmospheric constituents, metamorphic activity and ecology. Marine chemistry deals with the circumstances and collaborations between organic and inorganic compounds and the physical geological and biological conditions and the interactions of chemical systems with the marine organisms in the ocean.

Alga culture
Alga culture is the profitable mowing of algae. It is a type of aquaculture. A chief portion of the algae that are deliberately developed fall into the classification of microalgae additionally alluded to as phytoplankton, microphysics, or planktonic green growth. Macro algae, normally well-known as kelp, furthermore have copious uses, however, because of their size and the environmental necessities in which they have to develop, they don't lend themselves as punctually to progress on an extensive scale as microalgae and are repeatedly harvested wild from the sea.

Offshore Aquaculture
Offshore aquaculture, also identified as open ocean aquaculture, is an emergent methodology to Mari culture or marine farming where fish farms are inspired some distance offshore. The farms are sited in deeper and less sheltered waters, where ocean streams are stronger than they are inshore. One of the anxieties with inshore aquaculture is that discarded nutrients and feces can resolve below the farm on the seafloor and impairment the benthic ecosystem. Multi-functional usage of offshore waters can prime to more sustainable aquaculture "in areas that can be instantly used for other accomplishments such as energy production". The ecological impacts of offshore aquaculture are fairly uncertain because it is still largely in the research stage.

Mollusc Health and Diseases
Mollusca are the second largest phylum of invertebrate animals. The members are known as molluscs or mollusks. Mollusks play a multiplicity of roles in culture, containing but not limited to art and literature, with mutually practical interactions—whether useful or harmful—and symbolic uses.

Percid Culture
These wide work emphases on an imperative group of pleasant freshwater fish, It compiles the latest exploration on fish belonging to the Percidae family and defines in detail Biological aspects appropriate to the culture of altered species.

Genetic Engineering in Aquaculture
Genetic engineering through chromosome and gene manipulations holds promise for improving aquaculture production. Androgenic correspondingly involves production of progeny in which genetic material is absolutely derivative from male parent.

Aquaculture Health Management
Aquaculture is one of the principal developing sectors around the world to supply food, and an additional for wild caught fish. Aquaculture is commercial if optimal conditions and management practices are ensured in the fisheries, with close consideration to sustainability and ecology. The current trend in aquaculture enlargement is towards augmented magnification and commercialization of aquatic production. Like other farming sectors, the likelihood of foremost disease problems occurring increases as aquaculture activities intensify and expand. Thus, the aquaculture industry has been overcome with its share of diseases and problems caused by viruses, bacteria, fungi, parasites and other diagnosed and emerging pathogens. Disease is now a prime constraint to the culture of many aquatic species, obstructing both economic and social development in many countries.

Fish Vaccines
Aquaculture has been globally renowned as the wildest developing food production sector. The intensive farming of fin fishes and shellfishes has led to an inequity of optimal culture conditions, which displays increased vulnerability to infectious disease. Increased incidence of microbial diseases in aquaculture system is the major hindrance in the success of the industry. Vaccination is an easy, effective and preventive method of defending fish from diseases. Vaccination is a progression by which a protective immune response is prompted in an animal by administration of vaccines.

Integrated multi-tropic Aquaculture
The aquaculture production has grown up progressively owing to the dramatic expansion in this sector worldwide. Aquaculture out shined the supplies from the capture fisheries and subsidized nearly 51% to the global fish production in 2013. This accomplishment was possible essentially because of the commercialization of farm-produced aquatic groups such as the shrimps, salmon, bivalves, tilapia, and catfish. This sector also benefited from the substantial production of certain low-value freshwater species through integrated farming, envisioned for domestic production. One of the foremost challenges for the sustainable development of the aquaculture industry is to diminish environmental degradation concurrently with its expansion. Though the majority of aquaculture production patents from extensive and semi-intensive farming systems, the recent increase in intensive farming of marine carnivorous fed-species is associated with environmental concerns. Integrating waste generating (fed) and cleaning (extraction) organisms in Mari culture is a practical expertise for sustainable Mari culture. In a stable integrated system, aquaculture emissions can be converted into commercial crops while restoring water quality.
