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.
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.
The parasite is most known for its association with "salmon poisoning disease", which, left untreated, is fatal to dogs and other canids. However, canids are affected by the Neorickettsia helminthoeca bacteria, for which N. salmincola acts as a vector, and not by the parasite itself.
A single farm can contain a million or more fish, leading to high concentrations of diseases and parasites that kill farmed salmon and endanger nearby marine life and migrating wild salmon.
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 ...
Sea lice, particularly L. salmonis and various Caligus species, including C. clemensi and C. rogercresseyi, can cause deadly infestations of both farm-grown and wild salmon. [3] [30] Sea lice migrate and latch onto the skin of wild salmon during free-swimming, planktonic nauplii and copepodid larval stages, which can persist for several days.
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 ...
Wild salmon is more nutritionally dense than farm-raised salmon and can contain up to three times less fat, fewer calories, and more vitamins and minerals like iron, potassium, and b-12.
