Some internal fish parasites are spectacular, such as the philometrid nematode Philometra fasciati which is parasitic in the ovary of female Blacktip grouper; [14] the adult female parasite is a red worm which can reach up to 40 centimetres in length, for a diameter of only 1.6 millimetre; the males are tiny.
New Zealand is the largest producer of farmed king salmon, accounting for over half of world production (7,400 tonnes in 2005). [116] Most of the salmon are farmed in the sea (mariculture) using a method sometimes called sea-cage ranching, which takes place in large floating net cages, about 25 m across and 15 m deep, moored to the sea floor in ...

The virus was first described in 1976 in Scotland and in 1989 in Norway. It affects farmed Atlantic salmon (Salmo salar) caused by Marine SAV2 and SAV3 and has also been identified in Rainbow trout (Oncorhyncus mykiss) in the seawater phase caused by SAV2 where the disease is commonly referred to as Sleeping Disease (SD).

It was first described in rainbow trout in Germany in 1893, but its range has spread and it has appeared in most of Europe (including Russia), the United States, South ...
