Histopathological Studies

While investigating the trematode parasite infestation in the freshwater fishes of South Western Ghats, India we came across echinostome infection in three species of fishes Pseudosphromenus cupanus, Lepidocephalichthys thermlis and Aplochelus lineatus. Detailed histopathological studies on the infected kidney of the freshwater fish L. thermlis revealed severe damage and degeneration of their cells. The prevalence, intensity and mean abundance of infection of Echinostoma sp. in the three fishes were also recorded. The prevalences of Echinostoma sp. infection in the freshwater fishes P. cupanus, A. lineatus and L. thermalis were 5.55%, 66.66% and 25%, the intensities of infection were 4.5, 36 and 1, and the mean abundances were 0.25, 24 and 0.25, respectively.

Abstract Mungkus fish (Sicyopterus sp) is one of the freshwater fish that is caught by many people in Bengkulu Province. The mungkus fish are amphidromous and live in rocky rivers and fast-flowing rivers. This fish has a ventral sucker for sticking to rocks. The aim of this research was to determine the types of mungkus fish that can be found in Bengkulu Province waters based on morphometric characters. The research was conducted on 8 major rivers in 5 districts in Bengkulu Province including Argamakmur, Muko-Muko, Seluma, Manna, and Kaur. Based on the results, showed that the mungkus fish were characterized based on morphometric, there were 3 types of fish including Sicyopterus squamosissimus, Sicyopterus cynocephalus, and Sicyopterus lagocephalus. Mungkus fish found in the northern Bengkulu region tend to be smaller in size, have almost the same color pattern and darker body color than the fish found in the South Bengkulu region. The most common species found in Bengkulu is Sicyopterus squamosissimus. The Sicyopterus lagocephalus species can also only be found in rivers in the South Bengkulu region. The fish morphometric characteristics shows that differences in fish habitat will affect the growth of fish and the existence of living species in nature.

Abstract. The Western Ghats of India is a UNESCO World Heritage Site and is one of the eight “hotspots” of biological diversity in the world. It is also referred to as the “Great Escarpment of India”. This paper provides information on the diversity of freshwater fish fauna of six river systems of the southern Western Ghats. The study area has been identified geographically using a GPS, and the respective topographic map has been digitized using ArcGIS software. The fish fauna were collected from various streams and rivers using cast nets, dip nets, gill nets and drag nets. Among the 31 georeferenced sites sampled from the rivers of the southern Western Ghats, a total of 64 species, belonging to 6 orders, 14 families and 31 genera, were recorded. Among them, the order Cypriniformes was dominant, with 3 families, 18 genera and 49 species (76.6 %). Principal component analysis and cluster analysis were performed to express the contribution of the variables and their influence on the species diversity. Interestingly, of the 31 sites, Thunakadavu stream, Gulithuraipatti, Athirapally, Naduthotam, Nadathittu, Mullaithodu, Thonanthikla, Noolpuzha and Sinnaru exhibited high variation in species diversity. Nearly 15 species were found to be threatened in the Western Ghats. Garra periyarensis and Cirrhinus cirrhosus are known to be vulnerable and Hemibagrus punctatus is critically endangered because of various anthropogenic activities. The study clearly indicates that certain timely measures have to be taken immediately to protect the fish fauna in the southern Western Ghats (https://doi.org/10.1594/PANGAEA.882214).
