Rubble-mound breakwaters consist of piles of stones more or less sorted according to their unit weight : smaller stones for the core and larger stones for an armour layer protecting the core from wave action. (https://journals.openedition.org/mediterranee/7078)
An icebreaker is a special-purpose ship or boat designed to move and navigate through ice-covered waters, and provide safe waterways for other boats and ships. (https://en.wikipedia.org/wiki/Icebreaker)
A wind farm or wind park, also called a wind power station or wind power plant, is a group of wind turbines in the same location used to produce electricity. (https://en.wikipedia.org/wiki/Wind_farm)
In organic chemistry, transesterification is the process of exchanging the organic group R″ of an ester with the organic group R′ of an alcohol. These reactions are often catalyzed by the addition of an acid or base catalyst. (https://en.wikipedia.org/wiki/Transesterification)
Pig farrowing crates are metal crates within a pen where pregnant sows are placed prior to giving birth. Farrowing crates prevent the sows from turning around and only allow them to move a little forwards and backwards.

A sudden, large-scale fish mortality caused by factors such as oxygen deficit, inflow of toxicant, etc. (Anonymous (1998) AQUALEX. Multilingual glossary of aquaculture terms. https://www.fao.org/faoterm/viewEntry/en/?entryId=18873)
Note
Excessive or conspicuous mortalities of fish due to several causes
An acute clostridial infection of cattle, characterized by swelling beneath the skin due to gas formation in the tissues. (NALT https://lod.nal.usda.gov/nalt/67735)
Re-meandering is bringing a river back closer to its naturally meandering state by creating a new meandering course and by reconnecting cut-off meanders. (Adapted from: Office International de l’Eau, 2015. Natural Water Retention Measures. Glossary. http://nwrm.eu/concept/3872)
Postweaning multisystemic wasting syndrome, caused by porcine circovirus type 2 (PCV2), is a recently described clinical condition which affects nursery and growing pigs. PMWS is considered to be worldwide distributed. Clinically, PMWS most representative symptoms include wasting, unthriftness, paleness of the skin, respiratory distress, diarrhea and sometimes icterus. (Segalés J, Domingo M. Postweaning multisystemic wasting syndrome (PMWS) in pigs. A review. Vet Q. 2002 Sep;24(3):109-24. doi: 10.1080/01652176.2002.9695132. PMID: 12400999)
A tillage system which retains a high percentage of crop residue on the soil surface, thereby reducing wind erosion. (https://agclass.nal.usda.gov/mtwdk.exe?k=default&l=60&w=146922&n=1&s=5&t=2)
passive sonar is essentially listening for the sound made by vessels. Passive sonar listens without transmitting. It is often employed in military settings, although it is also used in science applications, e.g., detecting fish for presence/absence studies in various aquatic environments.

A variety of seaweed produced and maintained by cultivation. Cultivar is a contraction of the words "cultivated" and "variety". (FAO. 2024. The State of World Fisheries and Aquaculture 2024. Blue Transformation in action. Rome. https://doi.org/10.4060/cd0683en)
