The part of the catch that is not retained on board and is returned at sea, dead or alive. It may include target species or any other species (both commercial and non-commercial) discarded at sea. (Monitoring the incidental catch of vulnerable species in Mediterranean and Black Sea fisheries, FAO Fisheries and Aquaculture Technical Paper No. 640, FAO/GFCM, 2019.)
Note
Fish released/returned to the sea, dead or alive, whether or not brought fully on board a fishing vessel.
Zabrus asiaticus is a species of ground beetle in the Pelor subgenus. It was described by Francis de Laporte de Castelnau in 1834 and is found in Bulgaria, Greece, Romania, the North Aegean islands, European part of Turkey and the Near East. (Wikipedia. 2025. Zabrus asiaticus. https://en.wikipedia.org/wiki/Zabrus_asiaticus)
An overall average deriving from sampling and expressing how much fish (all species) is caught by a unit effort. (Sample-Based Fishery Surveys - A Technical Handbook, FAO, 2002 (http://www.fao.org/3/Y2790E/y2790e03.htm).)
Note
Catch per unit of effort (CPUE) is often considered an index of fish biomass (or abundance). Sometimes referred to as catch rate. CPUE may be used as a measure of economic efficiency of fishing as well as an index of fish abundance.
Subsistence economy is an economy directed to basic subsistence (the provision of food, clothing, shelter) rather than to the market. (Source: UNCTAD. 2022. UNCTAD Development and Globalization: Facts and Figures 2021. Glossary. https://doi.org/10.18356/9789210010375 (also available at https://dgff2021.unctad.org/annexes/glossary/subsistence-economy/ ))
In fluid dynamics, the drag coefficient a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water. (https://en.wikipedia.org/wiki/Drag_coefficient)
Use of water for activities like bathing, swimming, water-sports and river walks. It includes the water found in pools, rivers, seas, ponds and waterfalls. Includes water use not only for primary contact activities e.g. swimming, but also for secondary contact activities, such as boating and fishing.

"Wave analysis” incorporates the procedures for estimating, calculating or diagnosing wave conditions. There is a direct relationship between wind and waves, which, in principle, is a matter of calculation by manual or automatic means.

Acceptance testing: process of determining whether an implementation satisfies acceptance criteria and enables the user to determine whether to accept the implementation. (ISO 19105:2000)
Application of tools, implements and powered machinery as inputs to achieve agricultural production The term covers the manufacture, distribution, maintenance, repair, management, and utilization of agricultural tools, implements and machines. It applies to agricultural land development, crop production, harvesting and preparation for storage, on farm processing and rural transport. (http://www.fao.org/publications/card/en/c/c51ef369-668f-5a7c-acc2-b82b7055934f/)
Technosols combine soils whose properties and pedogenesis are dominated by their technical origin. They contain a significant amount of artefacts (something in the soil recognizably made or strongly altered by humans or extracted from greater depths) or are sealed by technic hard material (hard material created by humans, having properties unlike natural rock) or contain a geomembrane. They include soils from wastes (landfills, sludge, cinders, mine spoils and ashes), pavements with their underlying unconsolidated materials, soils with geomembranes and constructed soils. Technosols are often referred to as Urban or Mine soils. They are recognized in the Russian soil classification system as Technogenic superficial formations and in the Australian soil classification, they are included in Anthroposols. (IUSS Working Group WRB. 2015. World Reference Base for Soil Resources 2014, update 2015 International soil classification system for naming soils and creating legends for soil maps. World Soil Resources Reports No. 106. FAO, Rome.)
Immunohistochemistry (IHC) is the most common application of immunostaining. It involves the process of selectively identifying antigens (proteins) in cells of a tissue section by exploiting the principle of antibodies binding specifically to antigens in biological tissues (https://en.wikipedia.org)
