Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater and fresh water together, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root brak. Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment.

It is a marine, boreal fish which is known from the northwestern Pacific Ocean, including the Sea of Okhotsk and Japan. It dwells at a depth range of 15 to 269 m, and inhabits rocky reefs. Males can reach a maximum total length of 44 cm (17 in), but more commonly reach a TL of 31.5 cm (12.4 in). The maximum recorded weight is 1 kg (2.2 lb).
Aphyonus is a genus of blind cusk eels from the family Aphyonidae. It contains four species. A sampling of specimens of Aphyonus showed that the type species of Aphyonus, A. gelatinosus, was not closely related to the other known species in the genus, and a new genus Paraphyonus was named for these, including two newly identified species. The result of this classification is that Aphyonus would be a monotypic genus.
Notoscopelus bolini is a species of lanternfish in the family Myctophidae. It is found in the North Atlantic Ocean and the Mediterranean Sea.
