The trial was carried out on 405 cultured rainbow trout fish ranging in length from 47.8 to 69.8 cm and in weight from 1300 to 1920 g. The same experiment was carried out on 2,70000.00 trout fish eggs from November 2010 to April 2011 at a trout fish farm, in Kokernag, India, on account of the susceptibility of eggs to fungal infestation. The infected fish showed signs of lethargy, irritation, loss of appetite, haemorrhages at the base of fins and deep wounds at the sites of severe infection associated with cottony wool like tufts on both the dorsal and ventral sides of the body. The fungi were isolated at high percentages from skin followed by fins and mouth. The haemato-biochemical profile was studied in forty (40) normal and forty (40) infected fish. The haemoglobin content, total erythrocyte count, packed cell volume, lymphocyte percentage, total serum protein, albumin and globulin levels decreased significantly (p<0.05) in the Saprolegnia infected fish as compared to that in the control. The white blood cells, erythrocyte sedimentation rate, mean corpuscular haemoglobin, mean cell volume, heterophill percentage and total serum glucose showed significant increase in the infected fish irrespective of sex. The infection was more pronounced during the winter season (Temp.<10°C) as compared to that in summer (temp.<17°C). Fungi induced stress leads to haemostatic imbalances in fish reflected in the haematobiochemical profile and can thus be used as an indicator for Saprolegnia induced infection.

There is no outlet to the lake and loss of water is only through evapotranspiration. The lake was found to be highly alkaline (pH ≤ 9.0) with high conductivity (≥ 1639 S) and nutrients (NH4-N ≥ 54 g/L; NO 3-N ≥ 299 g/L; TP ≥ 464 g/L) as compared to its inlet Cheshul stream. The progression of the cations in the lake was Mg ++ > Na + > K + > Ca ++ while as in the stream it was Ca ++ > Mg ++ > Na + > K +. Mg ++ content in the lake was higher than the Ca ++ and Na + due to its more solubility. The lake belonged to cold monomictic group of lakes. Twentythree identified and some unidentified taxa of phytoplankton were recorded in the lake while as the periphytic community in the stream was represented by 34 taxa. Zooplankton in the lake was represented by only red coloured copepods, Diaptomus spp. and their larvae. No fish was observed in the lake while as in the stream three fishes Schizopygopsis stoliczkae, Triplophysa stoliczkae and Triplophysa gracilis were recorded. The low biodiversity in the lake was found due to high salinity and harsh environmental conditions prevailing in the lake. The inorganic nitrogen in the lake was recorded in very low concentration, Phosphate, on the other hand was present in very high concentrations. It seemed that instead of phosphate, nitrogen may act as a limiting factor for the aquatic community in the lake.

A total of 180 individuals are collected from the two locations, and a truss network is constructed by interconnecting 12 landmarks to yield 30 distance variables that are extracted from digital images of specimens using tpsDig2 and PAST software. Transformed truss measurements are subjected to Principal Component Analysis (PCA), where the first component explains 78.43% of total variance, while the second and third components explain 4.62 and 2.91% of total variance respectively. The high component loadings are from the characters which mostly contribute to anterior half of body depth, middle portion of body depth, and head region. The bivariate plot of PC1 and PC2 clearly indicates the separation of the two populations. The cross validation of this analysis reveals that the percentage of correctly classified fishes is 100% both in Dal Lake as well as Jhelum River.

Th... more In this paper, we studied the food and feeding habits of exotic Cyprinus carpio Var. communis. The results obtained by analysing the gut contents of common carp showed that on an average basis, detritus formed 43.5% of total food, while the remaining food (56.5%) consisted of plant (31.21%) and animal matter (25.29%). The fish was designated as detri-omnivore with bottom feeding habit. Gastroosmatic index (Ga.S.I.) recorded its highest value during July (6.28), while lowest value was recorded in February (3.34).The index remained generally high during the warmer months, followed by a gradual decline with the approach of winter. On comparing, food and feeding habits and Ga.S.I. of exotic common carp with that of endemic schizothoracines was found almost similar and there might be existing a feeding competition between them, which might be one of the cause that declined endemic schizothoracine fish production from Dal Lake of Kashmir valley.

The study was carried at three Zones (upstream, midstream and downstream) of varied topography and physical characteristics. The distributional pattern of these Schizothoracines varied at different zones though present throughout the year. S. plagiostomus was the dominant fish in the River, upstream the number of fishes of all the three Schizothorax species was low but the specimens were heavier and older and the trend was reverse downstream. Triplophysa kashmirensis and C. diplochilus were recorded only in the downstream of the River. Salmo trutta fario and G. reticulatum were present in the midstream and upstream only. The value of “n’ in Schizothoracine fishes fluctuated between 2.9467 to 3.0997. The maximum c...

The study was carried at three zones (upstream, midstream and downstream) of varied topography and physical characteristics. The habitat of each zone was determined with respect to some environmental factors. A progressive degradation in water quality and the species density and diversity along the altitudinal gradient in the downstream was observed. Macro-zoobenthos was represented by 21 taxa, among which insects dominated the benthic fauna throughout the stretch of the stream. The mean species density and diversity in upstream and downstream was 735 ind./m 2 and 19 sp. and 483 ind./m 2 and 14 sp. respectively. Sensitive species like Ephemerella spp. and Caenis srinagari occurred in the upstream only. Below upstream due to the increased nutrient influx and change in bottom texture and ecological setup, the density of Gastropods, Annelids and Diptera (e.g. Chirnomous meign) increased. The species diversity index (H 0) was high near the mouth of the river. One way ANOVA test showed significant variation between the upstream and downstream.

The trial was carried out on 405 cultured rainbow trout fish ranging in length from 47.8 to 69.8 cm and in weight from 1300 to 1920 g. The same experiment was carried out on 2,70000.00 trout fish eggs from November 2010 to April 2011 at a trout fish farm, in Kokernag, India, on account of the susceptibility of eggs to fungal infestation. The infected fish showed signs of lethargy, irritation, loss of appetite, haemorrhages at the base of fins and deep wounds at the sites of severe infection associated with cottony wool like tufts on both the dorsal and ventral sides of the body. The fungi were isolated at high percentages from skin followed by fins and mouth. The haemato-biochemical profile was studied in forty (40) normal and forty (40) infected fish. The haemoglobin content, total erythrocyte count, packed cell volume, lymphocyte percentage, total serum protein, albumin and globulin levels decreased significantly (p<0.05) in the Saprolegnia infected fish as compared to that in the control. The white blood cells, erythrocyte sedimentation rate, mean corpuscular haemoglobin, mean cell volume, heterophill percentage and total serum glucose showed significant increase in the infected fish irrespective of sex. The infection was more pronounced during the winter season (Temp.<10°C) as compared to that in summer (temp.<17°C). Fungi induced stress leads to haemostatic imbalances in fish reflected in the haematobiochemical profile and can thus be used as an indicator for Saprolegnia induced infection.

The mean species density and diversity in upstream and downstream was 735 ind./m 2 and 19 sp. and 483 ind./m 2 and 14 sp. respectively. Sensitive species like Ephemerella spp. and Caenis srinagari occurred in the upstream only. Below upstream due to the increased nutrient influx and change in bottom texture and ecological setup, the density of Gastropods, Annelids and Diptera (e.g. Chirnomous meign) increased. The species diversity index (H 0) was high near the mouth of the river. One way ANOVA test showed significant variation between the upstream and downstream.

Water, fish, and parasite samples were collected during different seasons from various sites and processed. Three fish species, namely, Schizothorax niger Heckel 1838, Schizothorax esocinus Heckel 1838, and Schizothorax curvifrons Heckel 1838, were recovered from these water bodies. The physicochemical parameters temperature, dissolved oxygen, pH, and free carbon dioxide showed variation vis-à-vis the season and location of the stations in water bodies. Acanthocephalan parasite Pomphorhynchus kashmirensis Kaw 1941 (27.47%) and two intestinal cestodes Bothriocephalus acheilognathi Yamaguti 1934 (30.63%) and Adenoscolex oreini Fotedar 1958 (32.43%) were recovered from all the three species of Schizothorax. All the three parasites showed higher prevalence during summer and the least pr...

Research paper thumbnail of Alteration in hematology of Cyprinus carpio under the stress of pollution of water bodies of Kashmir valley

Therefore a field study was conducted to investigate the blood profile of C. carpio collected from two water bodies of Kashmir valley, Dal and Mansbal lake as fish blood shows signs of pathological changes even before the onset of external symptoms of toxicity and it truly reflect the physical and chemical changes occurring due to pollutant accumulation in the fish body. Significant increase (p<0.05) was found in erythropoietic tissues vis-à-vis Hb, PCV and RBC count in C. carpio from Mansbal Lake compared to Dal lake. However, a significant decrease (p<0.05) was found in WBC count in C. carpio from Mansbal Lake compared to Dal Lake. More pronounced changes (p<0.05) were found in the values from Dal Lake compared to Mansbal Lake. Results showed in all the parameters studied, it was...

Five biochemical parameters which include glucose, triglycerides, cholesterol, total protein and urea were studied. Fishes were divided into 5 treatment groups and a control group and injected with the hormone @ 0.1, 0.2, 0.3, 0.4 and 0.5 ml Kg body weight. Control was injected with propylene glycol. The results showed a significant rise in the levels of cholesterol, triglycerides and protein in all hormone treated groups where as a significant decrease in urea concentration was observed with the increasing dose of hormone. Glucose only showed a significant increase in groups treated with higher doses of hormone (T3, T4 and T5).
