Comprehensive review on parasitic infections reported in the common fish found in UT of Jammu and Kashmir, India

Abstract

The people of Jammu and Kashmir rely heavily on fish as a source of nutritional protein. Fishes also contribute significantly to the local economy of this area. However, several infectious disorders, some of which are brought on by helminth parasites, constitute a persistent threat to fish. The primary goal of the present review is to find out the parasites in common fishes found in Jammu and Kashmir as well as the impact of parasites on fishes and sickness on human health. Like other animals, fishes are susceptible to several diseases, many of which are external in origin while others are internal in origin. Fishes are known to be susceptible to parasites, fungi, bacteria, viruses, and other external agents that can cause disease, and they also commonly experience organic and degenerative problems internally. Fish parasites have significant impact on both fish and human health. These diverse organisms, including protozoa, helminths, and crustaceans, can infest various fish tissues, leading to detrimental effects. Infested fish often experience reduced growth, weakened immune system, behavioral changes, physical damage, and even mortality. Economically, fish parasites can diminish the value of fish in markets and increase production costs in fisheries and aquaculture. Moreover, fish parasites pose potential human health risks. Consumers who ingest raw or undercooked fish containing certain parasites, like Anisakis spp., may develop gastrointestinal discomfort or anisakiasis. Proper cooking and freezing can mitigate this risk. While fish parasites are primarily harmful, they also play ecological roles, contributing to biodiversity and ecosystem stability by controlling fish populations. Understanding the complex interactions between parasites, fish, and their environment is vital for effective fisheries management, aquaculture practices, and public health measures. Striking a balance between controlling parasite infestation and maintaining ecological integrity is crucial for sustaining both fish populations and human well-being.
