Intensive agriculture, also known as intensive farming (as opposed to extensive farming), conventional, or industrial agriculture, is a type of agriculture, both of crop plants and of animals, with higher levels of input and output per unit of agricultural land area.
Comprehensive instrumentation and sensor controls are required to monitor this equipment and the underlying water conditions such as temperature, dissolved oxygen, and pH. Development of recirculating aquaculture systems is still underway in 2017, and engineering advances are needed to make the systems economically viable for culturing most ...
Aquaculture is also a practice used for restoring and rehabilitating marine and freshwater ecosystems. [3] Mariculture, commonly known as marine farming, is aquaculture in seawater habitats and lagoons, as opposed to freshwater aquaculture. Pisciculture is a type of aquaculture that consists of fish farming to obtain fish products as food.
Recirculating aquaculture systems (RAS) are used in home aquaria and for fish production where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity. [1] Other types of filtration and environmental control are often also necessary to maintain clean water and provide a suitable habitat for fish. [ 2 ]
As of 2016, more than 50% of seafood was produced by aquaculture. [3] In the last three decades, aquaculture has been the main driver of the increase in fisheries and aquaculture production, with an average growth of 5.3 percent per year in the period 2000–2018, reaching a record 82.1 million tonnes in 2018.
The challenge in these cases are due to the regulations stipulating that mangrove coverage need to be above optimal percentages, between 60-80%, which has led to over logging and the reluctance to practice silvoaquaculture. [8] [9] Other factors that can affect the production of shrimps in silvoaquaculture are the following: [4]
Since 2000, aquaculture has been the fastest growing food production sector, growing 5.8% per year, [6] supplying over 100 metric tonnes of fish, shellfish and seaweeds from 425 species in 2017. [3] [4] Global aquaculture production by country in million tonnes, 1950–2010, as reported by the FAO. Based on data sourced from the FishStat database.
Farmers combine fed aquaculture (e.g., fish, shrimp) with inorganic extractive (e.g., seaweed) and organic extractive (e.g., shellfish) aquaculture to create balanced systems for environment remediation (biomitigation), economic stability (improved output, lower cost, product diversification and risk reduction) and social acceptability (better ...
