Studies on trematode parasites of air breathing fishes of Awangsoi Lake, Manipur

The present investigation deals with a systematic survey of trematode parasites of air breathing fishes from Awangsoi Lake collected during 2008-2009. The air breathing fishes found in Awangsoi Lake are Channa punctatus, Clarias batrachus, Channa striatus, Channa orientalis, Anabas testudineus and Heteropneustes fossilis. During the study period the following 5 species of trematodes were collected : Clinostomum complanatum, Allocreadium handia, Allocreadium fasciatusi, Astiotrema reniferum and Genarcopsis goppo. The percentage of abundance was found to be maximum in Astiotrema reniferum and Anabas testudineus harbours the maximum number of parasites

Studies on nematode parasites of fishes of Oinam lake Bishnupur district, Manipur, India

An extensive survey was done for fish nematode parasites of few economically important fishes of Oinam Lake, Bishnupur district, Manipur. 9 species of nematodes were encountered. They are Camallanus anabantis, Procamallanus (Procamallanus) saccobranchi, Paraquimperia manipurensis, Paragendria sp., juvenile stages of genus Syphacia, Haplonema, Spinitectus, Philometra and Parascarophis etc. Of these nematode species, Procamallanus (Procamallanus) saccobranchi, Paragendria sp and Haplonema sp. showed maximum abundance (14.28%) and Paraquimperia manipurensis, Parascarophis sp. showed minimum abundance (4.76%) of parasites. Among the fish species Anabas testudineus had highest percentage (50%) of parasites and Puntius sophore and Colisa labiosus had lowest percentage (1.25%) of parasites

The present paper deals with the study of the seasonal variation on the occurrence of the Nematode Camallanus anabantis from the fish host Anabas testudineus from Loktak Lake, Manipur during May 2010- April 2011. A total of 460 number of A. testudineus has been sampled for the parasite infection and 335 fishes (71 %) has been found to be infected with the nematode thereby indicating high prevalence of infection of the nematode parasites in the fish

Phyllodistomum guptai n.sp. from body cavities of freshwater fish hosts Clarias batracus (Linn.), Heteropneustes fossilis (Bloch) and Channaguchua (Bloch) from Loktak lake, Bishnupur district. Manipur differs from all the known forms of the genus in the following characters viz. presence of pharynx. absence of oesophagus, ventral sucker larger than oral sucker, ovaries and testes are lobed, uterus intercaecal as well as extracaecal. &nbsp

SEASONAL OCCURRENCE OF HELMINTH PARASITES IN FISHES OF LOKTAK LAKE, MANIPUR

From four species of fishes namely Channa gachua (Ham), Channa striatus (Bl), Clarias batrachus (L.) and Anabas testudineus (Bloch.), five species of helminth parasites were collected comprising one species of digenetic trematode, two species of cestodes, one species of nematode and one species of acanthocephala. Nematode and acanthocephala showed moderate to high occurrence during different months while adult digenetic trematode and cestodes having quite low prevalance and even the infestation was absent during certain months of the investigation period

COMMERCIAL FOOD FISHES AND THEIR HELMINTH PARASITES DIVERSITY OF PUMLEN LAKE, TOKPACHING, MANIPUR

The present research paper which communicates with the objective to high light the diversity of fish as well as helminth parasite infection rate of the commercial food fishes of Pumlen Lake locally known as Pumlen Pat (- a Lake in Manipur) is the second largest freshwater wetland located in the Southern part of the Manipur valley. During the study period we come across 40 different species of fishes belonging to 27 genera, under 14 families and 7 orders. Of these, the most abundant is Trichogaster labiosa (6.37%), followed by Amblypharyngodon mola (5.84%) and Monopterus albus was least abundant (0.33%). And parasite infection is very common in the fishes like Clarias magur, Channa punctata, Channa striata, Channa orientalis Trichogaster fasciata, Trichogaster labiosa, Glossogobius giuris, Lepidocephalus guntea, Heteropneustes fossilis and Anabas testudineus. The study was conducted between January 2015 to December 2015 and found four groups of parasites in 280 fishes. The total parasitic infestation rate is 28.22%. The fishes belong to 5 different orders and 14 families. Among the fishes, 280 are found infected with helminth parasites belonging to four different groups in which 40 parasites belong to class acanthocephala, 25 parasites belong to class.Cestoda, 66 parasites belong to class Trematoda and l l parasites belongs to class Nematoda

ACANTHOCEPHALAN PARASITES 0F CERTAIN FISHES FROM MANIPUR, INDIA: ONE KNOWN SPECIES OF GENUS PALLISENTIS AND ONE NEW SPECIES OF GENUS ACANTHOCEPHALUS

The present investigation deals with the description of one known species, Pallisentis ophiocephali (Thapar, 1930) Baylis, 1933 from fish host Chaniia ,ctriatzis (BI.) from a new locality and description of one new species, Acanthocephahislokiakensis from fish host Channagachua (Ham.). A. Ioktakensis differs from all species of the genus Acanthocephalus in the size proboscis hooks and size of roots of hooks. The hooks-increase in size tìoni the apex towards the middle and thence gradually decrease towards the base

INFLUENCE OF HOST SPECIES, SEX, LENGTH AND DIFFERENT SEASONS ON THE HELMINTH PARASITE INFECTION IN FISHES OF DOLU LAKE, SILCHAR, ASSAM

The study was undertaken to determine the influence of host species, sex, length and different seasons on the prevalence of helminth parasite infection in fishes of Dolu Lake. A total number of 42 Heteropneustes fossilis, 111 of Channa punctatus and 46 of Notopterus notopterus were examined for parasitic infection. The results show that 9.52% of the examined H. .fossilis was infected with cestode and nematode while 23.42% of C. punctatus was infected with acanthocephalan, cestode and trematode. And 54.35% of N. notopterus was infected only with nematode parasite. The highest prevalence of infection was 54.35% in N. notopterus and lowest was 9.52% in H. fossilis. Female fishes were more parasitized than males. Autumn is found to be the season of severe parasitic infection where the percentage of infection is higher than the other seasons. Different trends of infection were found in different length groups of host species

A DIVERSITY OF HELMINTH PARASITE INFECTION OF THE FISHES OF JATINGA RIVER, ASSAM INDIA

Fishes are one of the important elements in the economy of many nations as well as they have been a stable item in the diet of many people, Parasites (in the larval stage) consumed in uncooked or undercooked seafood can present a human health hazard. Fish disease due to helminth parasites is one of the important problems in fish culture and fish farming. The importance of the fish parasites is related directly to the importance of the fish they may affect. There is a bewildering array of fish parasites and probably all the fish species harbour one or more parasite species. A total of 988 different fishes were sacrifices during my investigation, 20 different fish species were examined for helminth parasites infection. Of these 417 fish individual belonging to 14 different fish species are found to be parasitized with a total of 283 helminth parasites. River Jatinga contribute 49 fish species under 32 genera, 17 family and 6 orders. About 14 different species of parasite groups (viz. Nematode-NT, Acanthocephalan-AC and Cestodes-CT) including two new species were recorded from Jatinga River (Table 3). The prevalence and intensity is highest in Mastacebelus armatus and Mystus canvasius respectively (59.09%, 7.2) and lowest in Tenualosa ilisha, Channa punctata and Sperata alor respectively (3.13%, 0.5,0.5) of River Jatinga
