skimmer

skimmer
1) young silver bream, Abramis brama (Cyprinidae)
2) protein skimmer (an aquarium chemical filtration system which removes dissolved organic compounds and microscopic particles. Many small bubbles are sent through a column of water, forming a foam, to separate dissolved organic compounds from the water. The compounds and particles stick to the bubbles and are carried to the top of the unit where they are collected in a removable cup. They come in four varieties, downflow, venturi, counter-current, and co-current and are only really effective in salt water. They may be placed in the tank, hung on the side, or placed in a sump. Also called a foam fractionator)
3) a young man who catches with a hand net any herring that drop from the main net when it is hauled in (Scottish dialect)
