Intensive animal farming, industrial livestock production, and macro-farms, [1] also known as factory farming, [2] is a type of intensive agriculture, specifically an approach to animal husbandry designed to maximize production while minimizing costs. [3]
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.
Integrated mangrove-shrimp (IMS) aquaculture is a sustainable farming system used as one of the measures for mangrove rehabilitation and can be described as a method of organic aquaculture. [1] [2] Silvoaquaculture or silvofisheries are also terms used to define this farming practice where mangrove trees are planted alongside shrimp ponds ...
Pasture intensification is the improvement of pasture soils and grasses to increase the food production potential of livestock systems. It is commonly used to reverse pasture degradation , a process characterized by loss of forage and decreased animal carrying capacity which results from overgrazing , poor nutrient management , and lack of soil ...
The first step of nitrification in the biofilter consumes alkalinity and lowers the pH of the system. [10] Keeping the pH in a suitable range (5.0-9.0 for freshwater systems) is crucial to maintain the health of both the fish and biofilter. pH is typically controlled by the addition of alkalinity in the form of lime (CaCO 3) or sodium hydroxide ...
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.
[1] [3] [5] Fish and shrimp also release organic nutrients which feed shellfish and deposit feeders. [ 5 ] [ 26 ] [ 29 ] Species such as shellfish that occupy intermediate trophic levels often play a dual role, both filtering organic bottom-level organisms from the water and generating some ammonia.

Raising fish in cages in a lake in a relatively undeveloped environment. Urban aquaculture employs water-based systems, the most common, which mostly use cages and pens; land-based systems, which make use of ponds, tanks and raceways; recirculating systems are usually high control enclosed systems, [clarification needed] whereas irrigation is used for livestock fish.
