Bioinvasion: a paradigm shift from marine to inland ecosystems

Abstract

Anisakidosis is one of the most fearsome zoonotic food borne disease in aquaculture. The natural infections by anisakidoids or related variety in freshwater fish are not known, though sporadic experimental reports are available abroad (Butcher and Shamsi 2011). Invasive severity of anisakidoids in fish from Gangetic riverine ecosystems, i.e., in river Ganges at Fatehpur and Allahabad, as well as in river Yamuna at Allahabad, and molecular heterogeneity among these worms have been extensively investigated. The pathways of transmission of non-native alien species due to long distance migratory habits of Rita rita, man-made alterations including dredging in long stretches of the river bed of Ganges to facilitate ballast water transfer mechanism owing to the commercial ship movements between Haldia and Allahabad; and sudden water chemistry (salinity, hardness, alkalinity) alteration (due particularly to rainy period) oriented micro-fauna interchange are identified, and remedial measures suggested.

“…In recent years anisakidosis has emerged to be a pretty serious disease, that usually spreaded due to consumption of uncooked meat of fish (Timi et al, 2014). However, in Indian context noticeable advances have been made by the worms of Anisakidae where proven invasion of these worms from marine to freshwater ecosystems have been published (Jaiswal et al, 2016). Additionally, in the present investigation a more serious change in anisakid fauna from camallanid fauna to anisakid fauna over a longer period of time has been concluded.…”
