Parasites in fish are a common natural occurrence. Parasites can provide information about host population ecology. In fisheries biology, for example, parasite communities can be used to distinguish distinct populations of the same fish species co-inhabiting a region. [9]
The fish responds by walling off the parasitic infestation into a number of cysts that contain milky fluid. This fluid is an accumulation of a large number of parasites. Henneguya and other parasites in the myxosporean group have a complex life cycle where the salmon is one of two hosts. The fish releases the spores after spawning.
Kudoa thyrsites is a myxosporean parasite of marine fishes.It has a worldwide distribution, and infects a wide range of host species. This parasite is responsible for causing economic losses to the fisheries sector, by causing post-mortem "myoliquefaction", a softening of the flesh to such an extent that the fish becomes unmarketable.
DNA barcoding is a relatively cost-effective and quick method for identifying fish species aquatic environments. [7] Presence or absence of key fish species can be established using eDNA from water samples and spatio-temporal distribution of fish species (e.g. timing and location of spawning) can be studied. [8]
There are 52 species of Cryptobia known from fish. 40 of these live in the blood, 7 in the gut, and 5 on the body surface. [1] Examples include: Cryptobia branchialis, an ectoparasite that lives on the skin or gills. It can deform the skin and cause anorexia and death.
The infected fish also becomes lethargic, swims near the surface, and its appetite decreases. [10] Additionally the infected fish may hold its gill covers open and scratch its gills on rocks. [14] In severe infections, Dactylogyrus species can cause hemorrhaging and metaplasia of the gills which can lead to secondary bacterial infections and ...
