FINGERLINGS AND OTHER LINGS

摘要

To produce fish of edible size, in most cases fish farmers populate their ponds or fish cages with young stages of the preferred fish species.In the wild the process starts as fertilised eggs develop -although most eggs do not survive to maturity even under the best conditions, They are Beset with threats, from changes in water temperature or oxygen levels to flooding with the wrong sort of water, sedimentation that can cover the eggs with a layer of mud, and then there are disease and predation.Well, who doesn't like eggs? Then, there is the caviar. Traditionally, the term caviar refers only to roe from wild sturgeon in the Caspian and Black Seas (Beluga, Ossetra and Sevruga caviars). Depending on the country, caviar may also be used to describe the roe of other fish such as salmon, steelhead, trout, lumpfish, whitefish, other species of sturgeon, and even carp.
