A term used by a fisheries management agency which refers to the range of allowable catch for a species or species group. It is set each year by a scientific group created by the management agency. The agency then takes the allowable biological catch estimate and sets the annual total allowable catch (TAC). (FAO, 2009. A Fishery Manager's Guidebook. http://www.fao.org/3/i0053e/i0053e.pdf)

Rotational grazing is a system where a large pasture is divided into smaller paddocks allowing livestock to be moved from one paddock to the other easily. Using this method animals are concentrated on a smaller area of the pasture for a few days then moved to another section of pasture. (Adapted from University of Kentucky. MARTIN-GATTON COLLEGE OF AGRICULTURE, FOOD AND ENVIRONMENT, Rotational vs. Continuous Grazing https://grazer.ca.uky.edu/content/rotational-vs-continuous-grazing)
Rotaviruses (RVs) are a large genetically diverse population of segmented double-stranded (ds) RNA viruses that are important causes of gastroenteritis in many animal species. (Patton JT. Rotavirus diversity and evolution in the post-vaccine world. Discov Med. 2012 Jan;13(68):85-97. PMID: 22284787; PMCID: PMC3738915.)
A white crystalline substance, effective principle in insecticides and fish poisons obtained from the roots of plants, specially an Amazonian tree (Lonchocarpus) and the Indian derris. (Fish farming handbook, Institute of Aquaculture (SEAFDEC), Philippines, 1980.)

In their basic form, land deals involve at least two parties. On the one hand, there is an acquirer, generally a private or joint equity company, but it can also be a foreign government acquiring land directly. On the other side of the deal is a land provider, either a government or, much more rarely, a private land-owner. Each “deal” may involve multiple contracts and legal instruments. (FAO. 2003. Land grab or development opportunity? https://www.fao.org/4/ak241e/ak241e00.htm)
