Glacial erosion includes processes that occur directly in association with the movement of glacial ice over its bed, such as abrasion, quarrying, and physical and chemical erosion by subglacial meltwater, as well as from the fluvial and mass wasting processes that are enhanced or modified by glaciation. (Michèle N. Koppes, in Reference Module in Earth Systems and Environmental Sciences, 2020 https://www.sciencedirect.com/referencework/9780124095489/earth-systems-and-environmental-sciences)
Freehold title is the right to private ownership of land, free of any pre-eminent rights, such as exist under the feudal system. In most cases, the term ‘freehold’ may be used interchangeably with private land ownership. (Land Tenure Lexicon. A Glossary of Terms from English and French Speaking West Africa

A zoonotic disease (a disease that is transmitted to humans from animals) that is caused by parasites, namely tapeworms of the genus Echinococcus. (Echinococcosis, WHO, 2019 (https://www.who.int/news-room/fact-sheets/detail/echinococcosis).)
A method of production using processes and systems that are non-polluting, conserve non-renewable energy and natural resources, are economically efficient, are safe for workers, communities and consumers, and do not compromise the needs of future generations. (Foresight. The Future of Food and Farming (2011). Final Project Report. The Government Office for Science, London.)
Use of aggregates of bacteria, algae, or protozoa, held together in a matrix along with particulate organic matter for the purpose of improving water quality, waste treatment and disease prevention in intensive aquaculture systems. Consumption of bioflocs also provides nutritional value to cultured species. (ASFA)
Guar meal is the main by-product of guar gum production. It is a mixture of germs and hulls at an approximate ratio of 25% germs to 75% hulls (Lee et al., 2004). A protein-rich material containing about 40% protein in the DM, it is used as a feed ingredient, but may require processing to improve palatability and remove antinutritional factors (https://www.feedipedia.org/node/311)
Any wood or wood fuel which is derived from such products or processes as pallets, skids, spools, packaging materials, bulky wood waste or scraps from newly built wood products, provided such wood is not treated wood.

Strike-slip faults are vertical (or nearly vertical) fractures where the blocks have mostly moved horizontally. (https://earthquake.usgs.gov/learn/glossary/?term=strike-slip)
In epidemiology, an infection is said to be endemic in a population when that infection is constantly maintained at a baseline level in a geographic area without external inputs. (https://en.wikipedia.org/wiki/Endemic_(epidemiology))
The sum of natural and fishing mortality rates. Annual or seasonal. The number of fish which die during a year (or season), divided by the initial number. Also called: actual mortality rate, *coefficient of mortality (Heincke). (Restrepo V. (1999): Annotated Glossary of Terms in Executive Summary Reports of the International Commission for the Conservation of Atlantic Tunas´ Standing Committee on Research and Statistics (SCRS). ICCAT; Ricker W.E. (1975): Computation and interpretation of biological statistics of fish populations. Bulletin of the Fisheries Research Board of Canada, 191: 2-6)
The culture of larvae, usually in hatcheries, (Glossary of aquaculture/Glossaire d’aquaculture/Glosario de acuicultura. Rome, FAO. 2008. 401p. https://www.fao.org/3/a1555m/a1555m.pdf)
A wave tank is a laboratory setup for observing the behavior of surface waves. The typical wave tank is a box filled with liquid, usually water, leaving open or air-filled space on top. At one end of the tank, an actuator generates waves; the other end usually has a wave-absorbing surface. (Wikipedia. 2025. Wave tank. https://en.wikipedia.org/wiki/Wave_tank https://en.wikipedia.org/wiki/Wave_tank)
