Traditionally, fish that live all or part of their lives in fresh water were considered unsuitable for sashimi due to the possibility of parasites (see Sashimi article). Parasitic infections from freshwater fish are a serious problem in some parts of the world, particularly Southeast Asia. Fish that spend part of their life cycle in salt water ...
It can affect both freshwater and marine [1] fish. [2] [3] It appears as tiny black spots on the skin, fins, and flesh of the fish. The life cycle of the parasite typically involves a fish-eating bird, a snail and a fish. [4] The black spot larvae grow to sexual maturity in the infected bird's intestine. The adult worms pass eggs with the bird ...
These parasites are found worldwide, but are particularly common in South East Asia such as South Korea and the Philippines. The infection is usually acquired via the consumption of undercooked (or raw) freshwater fish, amphibians, mollusks or crustaceans contaminated with infective metacercaria.
Dactylogyrus species are monogenean parasites that are usually found on the gills of cyprinid fishes. [11] The prevalence of Dactylogyrus infection on fish differ depending on the seasons. It was found that Dactylogyrus infections are at their greatest during late autumn or early winter. [12]
The Naididae (including the former family Tubificidae) are a family of clitellate oligochaete worms like the sludge worm, Tubifex tubifex. They are key components of the benthic communities of many freshwater and marine ecosystems. In freshwater aquaria they may be referred to as detritus worms. [1]
The name literally translates as "the fish louse with many children". The parasite can infect most freshwater fish species and, in contrast to many other parasites, shows low host specificity. It penetrates gill epithelia, skin and fins of the fish host and resides as a feeding stage (the trophont) inside the epidermis.
Philometra is a genus of nematodes, which are parasites of marine and freshwater fishes. [1] The genus was erected by Oronzio Gabriele Costa in 1845. Species in this genus are worldwide. They parasitize the body cavities, tissues and ovaries of both marine and freshwater fishes.
