The histomorphology and gonadial cycle of a freshwater garfish Xenentoton cancila revealed that the ovaries of the fish pass through resting, early maturing advanced maturing, pre-spawning, spawning and spent phases within one year. The oogenetic activity starts in November and continues upto June(GSI=10.19)-July(GSI=11.38), when ovaries are full of yolky eggs. Only young oogonia and oocytes l appeared in September to October. The oocytes of l,ll,lll,lV and V stages were present during November to February. The oocytes Vl and Vll were seen dominated by ripe oocytes during June to late July when spawning takes place. Asychronism mode of oocyte development was recorded in X.cancila.

Abstract The study was conducted during September 2018-August 2019 to study the digenetic trematode infection in fresh water fishes of some of the water bodies viz. Gho-manhasan, Chakrali and Chadwal of Jammu region of J&K union territory A total of 220 fishes comprising Ophiocephalus punctatus and Xenentodon cancila belonging to families Channidae and Belonidae respectively were examined. A total of 4 digenetic trematode parasites belonging to 4 different families i.e., Euclinostomum heterostomum (Clinostomidae Luhe, 1901); Phyllodistomum tripathi (Gorgoderidae Looss, 1901); Genarchopsis piscicola (Hemiuridae, Luhe, 1901), and Bucephalopsis karvei (Bucephalidae Poche, 1907) were detected. The overall prevalence of digenetic trematode infection was 65.90% and the mean intensity was 3.58. Among these Genarchopsis piscicola showed the highest prevalence (40.38%) with mean intensity 2.95 in the host fish Xenentodon cancila, while in other species the prevalence ranged between 26.23% and 34.62%. Present study authenticates the presence of several species of digenetic trematode parasites in the fishes inhabiting freshwater of J&K union territory.

Present paper attempts to describe length-weight (LW) and total length-standard length (TL and SL) relationships of fresh-water garfi sh Xenentodon cancila. Fish of different length and weight were caught using cast nets from Muriyadhar, Sunsari. The fish were kept in ice box in fresh condition and brought to fi sh laboratory, Department of Zoolog post Graduate Campus, Biratnagar. The data obtained from measurement were analysed using the formula W = aLb. The b values estimated for the total length and standard length in relation to body weight were 3.2202 and 3.2559 respectively. The values of b clearly indicate the allometric growth pattern and for total length and standard length relationship, the linear value of b was 0.3223.J. Nat. Hist. Mus. Vol. 26, 2012: 10-14

The main objectives of the study were to determine the present status of fish biodiversity and socio-economic condition of fishermen in Belai beel during February 2016 to September 2016 by survey method using questionnaires, field visit and interviewing with the fishermen. The results indicated that about 27 species of fish fauna were found in the Belai beel, among them 23 species were indigenous and 4 species were exotic. Major dominant species were Rui (Labeo rohita), Catla (Catla catla), Bata (Labeo bata), Shingi (Heteropeneustes fossilis), Magur (Clarius batrachus), Tengra (Mystus tengra), Chanda (Chanda nama), Kakila (Xenentodon cancila), Common carp (Cyprinus carpio), Mola (Amblypharyngodon mola) in the study area. During the study period two critically endangered (Puntius sarana, Pangasius pangasius), two endangered (Labeo bata, Channa marulius), and three vulnerable (Chanda nama, Channa orientalis, Notopterus notopterus) fish species were found in the Belai beel. Analysis of socio-economic condition of fishermen showed that maximum (70%) had nuclear family and others (30%) had joint family, as well as fishermen, belonged to the age groups of 31 to 40 years (50%) and the others were 15 to 30 (20%), 41 to 50 (18%), 51 to 60 (10%), 61 to70 (2%). Overall, the present study suggested that fishermen communities should be educated by creating awareness for the proper conservation, management, and enhancement of biodiversity in the Belaibeel.Asian J.

Abstract The present paper deals with the infestation of freshwater fishes Labeo boggut, Oreochromis niloticus, Systomus sarana, and Xenentodon cancila by the parasitic isopods Alitropus typus and Tachaea spongillicola in Tapti, a westward freshwater flowing river of India. It is the first record of the infestation of parasitic isopods Alitropus typus, and Tachaea spongillicola in the freshwater fishes of river Tapti with new hosts’ species Labeo boggut, Oreochromis niloticus, and Systomus sarana.
