Aquaculture engineering is well known of agricultural engineering that studies cultured aquatic species and the production systems used in their culture. Study, research and development in this area ranges from low intensity man-made pond systems to highly intensive recirculation systems involving natural lakes. Aquaculture Waste management is One of the concerns with inshore aquaculture is that discarded nutrients and feces can settle below the farm on the seafloor and damage the benthic ecosystem. According to its proponents, the wastes from aquaculture that has been moved offshore tend to be swept away from the site and diluted. Moving aquaculture offshore also provides more space where aquaculture production can expand to meet the increasing demands for fish.

Sustainable aquaculture is a dynamic concept and the sustainability of an aquaculture system will vary with species, location, societal norms and the state of knowledge and technology. Several certification programs have made progress in defining key characteristics of sustainable aquaculture. Global warming and Aquaculture are interrelated processes, both of which take place on a global scale. Global warming affects Aquaculture in a number of ways, including through changes in average temperatures, rainfall, and climate extremes (e.g., heat waves); changes in pests and diseases; changes in atmospheric carbon dioxide and ground-level ozone concentrations; changes in the nutritional quality of sea foods; and changes in marine and fresh water aquaculture.

Fishing Equipment’s varies in sophistication depending on the size of the vessel and the technology used. Generally, on-board equipment can be categorized into three categories: related to the wheelhouse, to the fishing environment and to handling. Depending on the advanced technology and the aquaculture scope, similarly the fishing equipment is also now in deep advanced stage.  

Seafood is any form of sea life regarded as food by humans. Seafood prominently includes fish and shellfish. Shellfish include various species of molluscs, crustaceans, and echinoderms. Historically, sea mammals such as whales and dolphins have been consumed as food, though that happens to a lesser extent in modern times. Edible sea plants, such as some seaweeds and microalgae, are widely eaten as seafood around the world, especially in Asia (see the category of sea vegetables). In North America, although not generally in the United Kingdom, the term "seafood" is extended to fresh water organisms eaten by humans, so all edible aquatic life may be referred to as seafood. For the sake of completeness, this article includes all edible aquatic life. The harvesting of wild seafood is usually known as fishing or hunting, and the cultivation and farming of seafood is known as aquaculture, or fish farming in the case of fish. Seafood is often distinguished from meat, although it is still animal and is excluded in a strict vegetarian diet. Seafood is an important source of protein in many diets around the world, especially in coastal areas 

Edible seaweed is algae that can be eaten and used in the preparation of food. It typically contains high amounts of fiber and they contain a complete protein. They may belong to one of several groups of multicellular algae: the red algae, green algae, and brown algae. Seaweeds are also harvested or cultivated for the extraction of alginate, agar and carrageenan, gelatinous substances collectively known as hydrocolloids or phycocolloids. Hydrocolloids have attained commercial significance, especially in food production as food additives. The food industry exploits the gelling, water-retention, emulsifying and other physical properties of these hydrocolloids. Most edible seaweeds are marine algae whereas most freshwater algae are toxic. Some marine algae contain acids that irritate the digestion canal, while some others can have a laxative and electrolyte-balancing effect. 

Brackish water or briny water is water that has more salinity than fresh water, but not as much as seawater. It may result from mixing of seawater with fresh water, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root "brak". Certain human activities can produce brackish water, in particular certain civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment. Technically, brackish water contains between 0.5 and 30 grams of salt per litre more often expressed as 0.5 to 30 parts per thousand (ppt or ‰), which is a specific gravity of between 1.005 and 1.010. Thus, brackish covers a range of salinity regimes and is not considered a precisely defined condition. It is characteristic of many brackish surface waters that their salinity can vary considerably over space and/or time.

Like humans and other animals, fish suffer from diseases and parasites. Fish defences against disease are specific and non-specific. Non-specific defences include skin and scales, as well as the mucus layer secreted by the epidermis that traps microorganisms and inhibits their growth. If pathogens breach these defences, fish can develop inflammatory responses that increase the flow of blood to infected areas and deliver white blood cells that attempt to destroy the pathogens. Specific defences are specialised responses to particular pathogens recognised by the fish's body, that is adaptative immune responses. In recent years, vaccines have become widely used in aquaculture and ornamental fish, for example vaccines for furunculosis in farmed salmon and koi herpes virus in koi. Some commercially important fish diseases are VHS, ich and whirling disease.

The fish you cook and eat arrives in your wok, in your cooking pot and on your plate or table thanks to the efforts of many women and men working along the value chain from the sea, the lake, pond or cage through to the market kitchen and restaurant. Yet, fishing and fisheries has long been pictured as mainly the domain of men. Since 1998, the Asian Fisheries Society has explored the roles of women and the importance of gender analysis in fisheries and aquaculture through a series of global Symposia. The Gender in Agriculture Sourcebook presents a rich compilation of experiences, some of them ongoing, in which agricultural projects have incorporated gender-related components or adapted their operations to allow for gender variables and engage issues that affect men and women differently. It was produced jointly by the World Bank, the Food and Agriculture Organization (FAO) of the United Nations, and the International Fund for Agricultural Development (IFAD), drawing from the operations of these three agencies. It was released on October 8, 2008. The Gender in Agriculture Sourcebook describes the very often great practical consequences for the respective potentials of women and men as agricultural producers. The experiences chronicled capture a rich blend of hopeful innovations and cautionary lessons about the importance of avoiding the pitfalls of "gender-neutral" operations in areas in which gender issues are a salient variable in agricultural production - namely in the large majority of rural settings in low-income countries where agriculture remains a major engine of economic growth. Other lessons emerge from projects in middle income developing countries.

An invasive species is a plant or animal that is not native to a specific location (an introduced species); and has a tendency to spread, which is believed to cause damage to the environment, human economy and/or human health. The term as most often used applies to introduced species (also called "non-indigenous" or "non-native") that adversely affect the habitats and bioregions they invade economically, environmentally, and/or ecologically. Such invasive species may be either plants or animals and may disrupt by dominating a region, wilderness areas, particular habitats, or wildland-urban interface land from loss of natural controls (such as predators or herbivores). This includes non-native invasive species.

The Asia-Pacific Fishery Commission (APFIC), originally called the Indo-Pacific Fisheries Council (IPFC) is a Food and Agriculture Organization (FAO) Article XIV Regional Fisheries Body which covers fisheries, aquaculture and related aquatic resource issues in the Asia-Pacific region. APFIC functions as a Regional Consultative Forum raising awareness amongst member countries, fisheries organizations and fisheries professionals in the Asia-Pacific region. In recent years, APFIC has covered a range of regional fisheries issues, including co-management of fisheries, low value/trash fish (may be referred to as bycatch where not targeted catch) in the region, illegal, unreported and unregulated fishing (IUU) and fishing capacity management,certification in fisheries (e.g. ecolabel) and aquaculture, ecosystem approach to fisheries and aquaculture and improving resilience of fishery livelihoods. Most recently work has focussed on developing a training course for Ecosystem Approach to Fishery Management and guidelines for tropical trawl fisheries management.

The systems and technology used in aquaculture has developed rapidly in the last fifty years. They vary from very simple facilities (e.g. family ponds for domestic consumption in tropical countries) to high technology systems (e.g. intensive closed systems for export production). Much of the technology used in aquaculture is relatively simple, often based on small modifications that improve the growth and survival rates of the target species, e.g. improving food, seeds, oxygen levels and protection from predators. Simple systems of small freshwater ponds, used for raising herbivorous and filter feeding fish, account for about half of global aquaculture production. A greater understanding of complex interactions between nutrients, bacteria and cultured organisms, together with advances in hydrodynamics applied to pond and tank design, have enabled the development of closed systems. These have the advantage of isolating the aquaculture systems from natural aquatic systems, thus minimizing the risk of disease or genetic impacts on the external systems.

Aquaponics is a bio-integrated system that links recirculating aquaculture with hydroponic vegetable, flower, herb production. Recent advances by researchers and growers alike have turned aquaponics into a working model of sustainable food production. This publication provides an introduction to aquaponics with brief profiles of working units around the country. An extensive list of resources point the reader to print and Web-based educational materials for further technical assistance.
