Diseases and parasites in salmon, trout and other salmon-like fishes of the family Salmonidae are also found in other fish species. The life cycle of many salmonids is anadromous , so such fish are exposed to parasites in fresh water , brackish water and saline water.
Myxobolus cerebralis is a myxosporean parasite of salmonids (salmon and trout species) that causes whirling disease in farmed salmon and trout and also in wild fish populations. 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 ...
In the same study farm-raised salmon did not have any roundworm larvae. [69] Historically, parasite infection of humans eating raw fish has been rare in the developed world, though a 2020 meta-analysis of available data shows that since 1980 there has been a sharp increase of parasites in the types of marine fish that are eaten uncooked.
Workers prepare sides of fresh farmed salmon for filleting and packaging in the processing plant at a fish farm operated by Salmar ASA on the island of Froya, Norway, on Thursday, Aug. 7, 2014.
Ceratonova shasta (syn. Ceratomyxa shasta) is a myxosporean parasite that infects salmonid fish on the Pacific coast of North America. It was first observed at the Crystal Lake Hatchery, Shasta County, California, and has now been reported from Idaho, Oregon, Washington, British Columbia and Alaska. [2]
1. Farm-Raised Salmon. Some farm-raised salmon may contain more parasites than its wild-caught counterpart due to the densely populated conditions of fish farms, which can foster a breeding ground ...
Adult worms alternate shape from "a sphere to a long blunt rod". [12] The worms are 0.8 to 1.1mm long and 0.3 to 0.5 mm wide and are hermaphroditic, having both male and female reproductive organs in the same organism. The two large oval testes are 0.2 to 0.3 mm long and the round ovary is 0.07 to 0.11 mm in diameter. [11]
Amoebic gill disease (AGD) is a potentially fatal disease of some marine fish. It is caused by Neoparamoeba perurans, the most important amoeba in cultured fish.It primarily affects farm-raised fish of the family Salmonidae, most notably affecting the Tasmanian Atlantic salmon (Salmo salar) industry, costing the A$20 million a year in treatments and lost productivity.
