Abstract:

Consumption of fish has increased around the globe due to its high nutritional value and this has led to an increase in incidence of allergic reactions to fish. Reactions to fish are not only mediated by the immune system causing allergies but are often caused by proteins, metals, various toxins and parasites. Allergic reactions to fish can range from being mild and self-limiting to serious and life threatening. We report a case of an adult with suspected allergic reaction to Boal fish (Wallago Attu) who developed contact dermatitis during marinating process. Application of steroids and administration of oral antihistaminic led to a quick recovery.

Abstract:

Abstract The freshwater shark Wallago attu (Bl. and Schn.) is a frequent silurid in the River Ganga and one of the most commercially exploit fish in India. In a survey on its infection with myxosporeans, spore type belongs to Thelohanellus species was found in the gills, kidney and intestine respectively. Through morphological and molecular investigations, we identified the spore as Thelohanellus wallagoi Sarkar, 1985. They were pyriform in valvular view and slim in sutural view, and had one pyriform polar capsule with four to five turns. The spores measured 8.0 × 4.0 × 2.3 μm. T. wallagoi developed in small cysts in the gill lamellae, whereas cyst and scattered spores of T. wallagoi were also found in the kidney and intestine respectively. The 18S rDNA sequence of T. wallagoi isolates recovered from gills, kidney and intestine were found similar to each other and differed from any other Thelohanellus species available in GenBank and validated its status after 32 years of original description. Phylogenetic analysis signified that T. wallagoi was placed sister to Myxobolus species in the clade that indicated the polyphyletic nature of the genus Thelohanellus.

Abstract:

Definite cyclic variations were observed in blood urea levels of freshwater catfish Wallago attu. The maximal mean blood urea level (8.44±1.96 mg/100 ml) was noted in the month of June while minimal level in December, revealing a difference of 65.87% between the two levels. Seasonal alterations observed here in W. altu were correlated with ecophysiological factors like temperature, food availability, body metabolism, breeding cycle and hormonal changes which have been essentially found to be involved in fish life.

Abstract:

AbstractThe fish host (Wallago attu) and monogenoid parasite (Thaparocleidus sp.) have been recorded during 2 years (2011 and 2012) to investigate intra/interspecific interactions among query species (T. sudhakari (Gusev, 1976) Lim, 1996; T. indicus (Kulkarni, 1969) Lim, 1996; T. gomtius (Jain, 1952) Lim, 1996; T. yogendraii Agrawal, 1981 and T. wallagonius Jain, 1952) in the light of parasitic worm burden, morphological and molecular data. Each species is highly host specific (oioxenous), with a specialized functional niche. Being niche specialists, they exhibit niche overlapping along with co-existence due to reproductive barrier. Furthermore, a molecular marker, affirming clear-cut genetic variation in spite of structural entities, provides evidence for infra-speciation as well as co-speciation.

Abstract:

An investigation was carried out to compare the physical, chemical, microbiological and sensory properties of three freshwater dried fish products of Wallago attu Bloch & Schneider, 1801 (Siluriformes: Siluridae), Channa striatus (Bloch, 1793) (Perciformes: Channidae) and Glossogobius giuris (F. Hamilton, 1822) (Perciformes: Gobiidae). The traditionally sun dried fishes were collected from Kawran Bazar Fish Market, Dhaka, Bangladesh. Results showed that the water reconstitution properties varied among the dried fishes where maximum rehydration was observed in the C. striatus at room temperature, 40 oC and 60 oC. Moisture content of W. attu, C. striatus and G. giuris were 22.70% +/- 0.45%, 18.75% +/- 0.58% and 21.93% +/- 0.54%, respectively; the protein content were 61.85% +/- 0.99%, 66.44% +/- 1.02% and 62.83% +/- 0.87%, respectively; the lipid content were 6.21% +/- 0.93%, 6.81% +/- 0.72% and 5.98% +/- 0.55%, respectively, and the ash content were 6.79% +/- 1.11%, 6.49% +/- 1.29% and 7.83% +/- 0.98%, respectively. Peroxide value, acid value, pH, TVB N value and aerobic plate count were found to be highest in W. attu followed by G. giuris and C. striatus. Results of this study revealed that traditionally sun dried fish products were acceptable quality in terms of physico-chemical, microbiological and sensory aspects.

Abstract:

Summary Two species of Thaparocleidus Jain (1952a) were found harboring W. attu from the Ganga River at two localities, Meerut and Farrukhabad, Uttar Pradesh, India, during the period of 2013-2015. Morphology and morphometric study of specimens identified as Thaparocleidus gomtius (Jain, 1952a) Lim, 1996 and T. sudhakari (Gusev, 1976) Lim, 1996. Molecular analyses using the 18S rRNA gene confirmed the validity of T. gomtius and T. sudhakari and demonstrated that both the species clustered with other Thaparocleidus species from different geographical regions. We aim at reassessing the taxonomy and establishing the phylogenetic relationships among these two redescribed species with other representatives of the genus Thaparocleidus.

Abstract:

AbstractSpecies of the genus Mizelleus Jain (1957) have always been controversial regarding identification and validity. Members of this group of species differ from each other in the morphology of their hard parts, which can be misleading and subject to differing interpretation among scientists. Therefore, the main objective of present study was to identify Mizelleus worms by morphological methods and molecular analysis on the basis of 18S ribosomal DNA to clarify their phylogenetic status. In this study, specimens were isolated from the gill filaments of Wallago attu (Siluriformes) and studied morphologically. In accordance with morphological characters, the specimens were found to be Mizelleus indicus and Mizelleus longicirrus. Partial sequences of nuclear 18S rDNA of these two species were amplified. The results confirm the phylogenetic relationships and taxonomic validation of M. indicus and M. longicirrus in India.

Abstract:

The study was conducted to determine the nutritive value in terms of proximate composition, fatty acid (FA) profile and lipid quality indices off our catfish species (Wallago attu, Ompok pabda, Clarias gariepinus, Pangasidon hypophthalmus) and two murrel species (Channa striatus, Channa punctatus) from Odisha, India. Among the species investigated the maximum fillet protein (22.35%) and lipid (13.45%) was recorded in C. striatus and C. gariepinus, respectively. All the fish species showed a FA profile of saturated fatty acid (SFA)> mono unsaturated fatty acid (MUFA)>poly unsaturated fatty acid (PUFA). The n-3 PUFA distribution in the experimental species was observed as docosahexaenoic acid (DHA, 22:6 n-3)>alpha linolenic acid (ALA, 18:3 n-3)>eicosapentaenoic acid (EPA, 20:5 n-3) except C. gariepinus. The fillet EPA and DHA content of two murrel species and W. attu were similar and significantly higher (P<0.05) among the species. Similarly these three species viz., W. attu, C. striatus and C. punctatus showed maximum DHA quantity in their fillet. The n-6/n-3 ratios in five species except C. gariepinus were below 4.0. The athrogenic index (IA) and thrombogenic index (IT) were<1 and cholesterolomic index (h/H) for all species were>1, suitable for human health. Overall, considering nutritive value, fillet protein and very essential fatty acids, the experimental species can be arranged in the following order C. Straitus>C. punctatus=W. attu>P. Hypophthalmus>O. Pabda>C. gariepinus.

Abstract This study was conducted to assess water pollution by examining DNA fragmentation in selected fish organs (kidney, liver, gills, and muscle tissue) from Wallago attu, Sperata sarwari, Vulgaris vulgaris, and Labeo rohita collected from a known polluted section of the Chenab River, Pakistan, and from a control site. The fish were caught using a gill net and were assigned to three different weight groups (W1, W2, and W3) to study the degree of variation in DNA fragmentation in relation to body weight. In fish from the polluted site, DNA fragmentation was higher in kidney, liver, gills, and muscles, compared to the control. No significant DNA fragmentation was observed in fish collected from the control site. Highly significant (P < 0.01) relationship between body weight and DNA fragmentation was found in the organs of fish procured at the contaminated site. DNA fragmentation in body organs was found to be affected by the concentrations of lead, copper, nickel, and cadmium in W. attu, S. sarwari, L. rohita, and V. vulgarus harvested from Chenab River. DNA fragmentation in different freshwater fish species is therefore a reliable biomarker of water pollution.

Abstract:

AbstractThe present paper describes the taxonomy of two new monogeneans, namely, Thaparocleidus longiphallus sp. n. and T. siloniansis sp. n., based on morphological, morphometric and molecular biological analysis, collected from the fish Wallago attu (Bloch & Schn.) and Silonia silondia (Ham.), respectively, at Meerut, UP, India. Genetic characterization of the two new species is based on sequence analyses of the rDNA 28S gene using neighbour-joining and maximum-parsimony techniques. These methods are congruent in depicting T. longiphallus sp. n. and T. siloniansis sp. n. as closely related species, but distinct from each other and forming a subclade with other species of the genus Thaparocleidus Jain, 1952. Secondary-structure models of the large subunit rDNA of the two species were also predicted using a combined comparative and thermodynamic approach. Molecular morphometric and phylogenetic relationships of the isolates of the Thaparocleidus species are discussed in detail.

Abstract Six fish speciesCirrhinus mrigala (Morakhi), Labeo rohita (Danbhro), Catla catla (Thalli), Wallago attu (Jarko), Ctenopharyngodon idella (Grass), and Cyprimus carpio (Gulfam)commonly found in the Pakistani Indus river, were selected for fat and cholesterol evaluation. Fat content was quantified by the Folch method and cholesterol content was determined by a simple GC method. The application of the proposed method to quantify cholesterol content revealed variations among the six breeds evaluated. The breeds studied contained 0.801.95 fat, indicating that all investigated fishes were lean; significant variation was found in cholesterol content, and ranged between 72 and 392 mg/100 g. Standard addition analyses showed that the method was accurate, as the recovery of cholesterol varied from 95 to 103, with a coefficient of variance not more than 5.6. The results showed that, after the development of suitable calibration, within 11 min, the cholesterol could be accurately determined by GC.

Abstract:

The nutrient profile of five freshwater fish species viz., Mystus vittatus, Ompok bimaculatus, Channa striata, Wallago attu and Pangasianodon hypophthalmus were studied. The proximate composition data shows that the moisture and fat content differed significantly (P<0.01) among the fish species. The fat content was significantly higher in P. hypophthalmus and M. vittatus. The moisture was significantly higher in C. striata. The potassium content was significantly (p<0.01) higher in C.striata. M.vittatus shows higher content of calcium. The other trace minerals like iron, copper and zinc contents of fish did not differ significantly among the species. The vitamin A content is maximum in O.bimaculatus whereas vitamin D content is higher in Mystus vittatus. The palmitic acid was significantly (p<0.01) higher in M. vittatus. The oleic acid was significantly (p<0.01) higher in C. striata and W. attu. The linoleic acid content was significantly (p<0.05) higher in P. hypophthalmus. One of the important PUFA i.e. DHA was significantly higher in O. bimaculatus and C.striata. The PUFA content was significantly (p<0.05) higher in O.bimaculatus and P.hypophthalmus. Among the amino acids, arginine, histidine, threonine and isoleucine were higher in P.hypophthalmus. C.striata and W. attu contain high amount of Tryptophan. Glutamic acid was high in O.bimaculatus and Aspartic acid was high in C. striata. The energy content was maximum in P. hypophthalmus. The nutrient profile of these fish species revealed that they were rich in all the essential nutrients required by human being. The information on nutrient profile of fish will give a guideline to dieticians, nutritionists, medical practitioners, researchers to advice consumers to take fish in their daily diet as a health food.

Abstract:

Abstract We have investigated biochemical properties of myofibrillar proteins of the digenetic trematode Isoparorchis hypselobagri, which correlate with its survival in the oxygen-rich swim bladder of its host catfish (Wallago attu). The polypeptide composition of the trematode’s natural actomyosin (NAM) was striated-muscle-like, with the exception that a 98-kD polypeptide corresponding to paramyosin also existed in its sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) profiles. The profiles of immunoprecipitated NAM of the trematode support these inferences. Ca2+-sensitivity of myofibrillar contractility and Mg2+-ATPase activity of I. hypselobagri resembled troponin-linked calcium regulation of the host striated muscle. Myofibrillar permeability to water influx was insensitive to calcium chelation at neutral pH. However, the host swim bladder myofibrils displayed smooth-muscle-like polypeptide composition, pH dependence of contractility, Ca2+-sensitivity, ATPase activities, and inactivation kinetics. We propose 2 survival strategies that I. hypselobagri appears to have co-evolved: (i) fast-muscle-like musculature with exceptionally high contractility or ATPase activity; and (ii) type-II myosin resembling the host muscle in functional plasticity.

Abstract:

The contamination of aquatic systems with heavy metals is affecting the fish population and hence results in a decline of productivity rate. River Kabul is a transcountry river originating at Paghman province in Afghanistan and inters in Khyber Pakhtunkhwa province of Pakistan and it is the major source of irrigation and more than 54 fish species have been reported in the river. Present study aimed at the estimation of heavy metals load in the fish living in River Kabul. Heavy metals including chromium, nickel, copper, zinc, cadmium, and lead were determined through atomic absorption spectrophotometer after tissue digestion by adopting standard procedures. Concentrations of these metals were recorded in muscles and liver of five native fish species, namely,Wallago attu,Aorichthys seenghala,Cyprinus carpio,Labeo dyocheilus, andOmpok bimaculatus. The concentrations of chromium, nickel, copper, zinc, and lead were higher in both of the tissues, whereas the concentration of cadmium was comparatively low. However, the concentration of metals was exceeding the RDA (Recommended Dietary Allowance of USA) limits. Hence, continuous fish consumption may create health problems for the consumers. The results of the present study are alarming and suggest implementing environmental laws and initiation of a biomonitoring program of the river.

Abstract:

An experiment was carried out to know the carnivorous feeding nature of piranha (Pygocentrus nattereri) under laboratory condition for a period of 36 days. One-month old nine fish were stocked in nine separate glass aquaria having three feeding treatments each with three replications. Fish were fed with nursery feed (Sabinco feed) in treatment 1 (T1); 50% live + 50% dead small prawns (Macrobrachium rosenbergii) and small fishes (Esomus danricus and Amblypharyngodon mola) in treatment 2 (T2); and 100% live small prawn and fishes in treatment 3 (T3) twice a day at the rate of 10% body weight. The average weight gain was significantly (P<0.05) higher in T2 (21.02 ± 0.72) than in T1 (-1.824 ± 0.35) and T3 (15.36 ± 4.96). The SGR (% day-1) recorded was significantly (P<0.05) higher in T2 (12.04 ± 0.01) than T3 (11.77 ± 0.09). No unused feed was found in T2 and T3 but some unused feed was found in T1. The stomach length, gut length and the RLG values of piranha were significantly (P<0.05) higher than that of taki, Channa punctatus but not of boal, Wallago attu. The presence of razor sharp teeth in both jaws and 30-32 pyloric caeca with 1.84 RLG value are attributed to the piranha as carnivore.DOI: http://dx.doi.org/10.3329/pa.v21i1-2.16764 Progress.

Abstract:

A study was conducted to determine the ichthyofaunal diversity in Bankura district of West Bengal. The area is traversed by major and minor rivers, feeder channels, numerous ponds, bills, reservoirs which have made this drought-trodden district as the highest producer of aquatic products within the state. Field survey was conducted in randomly selected local markets covering twenty-two blocks of Bankura. Fish sampling was carried out using various conventional fishing gears. The entire region harbours a wide variety of aquatic fishes. A total number of 92 indigenous fish species belonging to 30 families were identified during this study. The Cyprinidae family dominated the population with its 36 varieties followed by Channidae, Siluridae and Bagridae. Sonamukhi block situated in Shali basin; Sarenga and Raipur of Kangsabati basin; Dwarkeshwar and seven bundhs- enriched Bishnupur were the major habitats of small indigenous fishes. This paper also denotes presence of 12 globally endemic freshwater fish species viz. Hypophthalmichthys molitrix, Cyprinus carpio, Labeo nandina, Tor khudree, Chitala chitala, Bagarius bagarius, Wallago attu, Ompok pabda, Ailia coila, Anguilla bengalensis, Parambassis lala, Oreochromis mossambicus. The substitution of native Clarias batrachus with invasive African catfish C. gariepinus was observed in various local markets. Some traders even promote illicit farming of this banned species for their own profit. As a consequence, the indigenous, nutritionally-enriched C. batrachus is becoming more endangered.

Abstract:

A checklist of the native fishes of the Dhanu River and adjacent waters at Mithamain Upazila under the Kishoreganj district of Bangladesh is prepared with details on their availability, conservation status, habitat preferences, population trends, and threats. Data were collected monthly by field survey, focus group discussions, and personal interviews by using a semi-structured questionnaire and a pictorial check list of fish species. A total of 91 indigenous fish species of 59 genera belonging to 29 families under 11 orders were documented where 17.6%, 27.5%, 31.9%, and 23.1% species were abundantly available, commonly available, moderately available, and rarely available, respectively. Among those, 24 fish species (26.4%) were under the threatened category (3 critically endangered, 11 endangered, and 10 vulnerable) according to the IUCN Bangladesh. Notably, the globally threatened Cirrhinus cirrhosus, Channa orientalis, and Wallago attu were available in the study area. Fish population trends of 24.2% and 59.3% of the entire fish species were found in decreasing trends at the global and national level, respectively. The leading threats to the fish diversity were indiscriminate overfishing followed by fishing by dewatering of wetlands, the katha fishing method, the use of deprecated fishing gears, etc. Minimizing anthropogenic impacts, enacting fishing laws, installing and managing fish sanctuaries, and raising public awareness can be effective for the conservation of existing fisheries resources.

Abstract:

A study was conducted in two districts namely Bogura and Sirajgang to investigate the marketing channel and the marketing system of fishes captured from the Jamuna river in Bangladesh during a period of two consecutive years from January 2016 to December 2017. Fish captured from the Jamuna river were marketed through three types of market viz. auction market/arat, wholesale market and retail market. Operators of the fish market were the fishermen, faria, aratders, paikers or baparies, whole sellers and retailers. Ten channels were identified through which fish of the Jamuna river were shifted from the fishermen to the consumers. The shortest channel was the fishermen to consumers while the longest one was the fishermen→faria→aratders→paikers→whole seller→retailer→consumers. The highest price of fish (BDT 560/kg) was recorded for Wallago attu in retail market followed by BDT 500/kg for Tenualosa ilisha and Bagarious bagarious while, five small indigenous species (SIS) Tetraodon cutcutia, Chanda nama, Parambassis lala, Parambassis ranga, and Esomus danricus got the lowest price in retail market. Icing, weighing, transportation, capital supply were required in fish marketing channels as supporting function to overcome crisis. Major constrains prevailing in the fish marketing channels were reducing fishing areas, decreasing fish catch per day per fishermen, disturbance by illegal seasonal fishermen, lack of bargaining power and market information, lack of proper fish storage and preservation facilities in the fishing craft and fish markets, wastage of fish due to spoiling during transportation, sanitations, drainage and management problems within the market areas.

Abstract:

Background. Pollution of the aquatic ecosystem by heavy metals is increasing due to anthropogenic activities. Cadmium (Cd) can accumulate in soil, be taken up by plants, and passed on in the food chain to animals and humans. Objectives. The present study was conducted to analyze the uptake of Cd in muscles of sampled fish with different feeding habits and to compare levels of Cd in fish from the Ayeyarwady River, Myanmar with international standards. Methods. The acid digestion procedure was used for sample preparation. Cadmium concentrations in fish samples were determined by flame atomic absorption spectrophotometry (Perkin Elmer AAanalyst 800 and Winlab-32 software). Results. In herbivorous fish species, Cd content ranged from 0.07 ( Catla catla ) to 0.086 mg/kg ( Osteobrama belangeri ). In carnivorous fish species, Cd ranged from 0.060 ( Mystus leucophasis ) to 0.083 mg/kg ( Wallago attu ). In omnivorous fish species, Cd ranged from 0.07 ( Botia histrionica ) to 0.084 mg/kg ( Gudusia variegata ). Cadmium content did not differ significantly across the three types of feeding habits (p>0.05). Discussion. The accumulation of Cd in the muscle of studied fish was lower than the permissible limit set down by the European Union in 2001 (0.1 ppm), but above the limits set down by the Food and Agriculture Organization/World Health Organization, European Commission (0.05 ppm) and within the limit of United States Food and Drug Administration (0.01–0.21 ppm). The data obtained in the present study indicate that levels of Cd were not significantly different across fish species with different feeding habits. Conclusions. The examined fish samples were not fully safe for human consumption due to high levels of Cd. Competing Interests. The authors declare no competing financial interests.

Abstract:

The study was conducted to assess the pollution of five heavy metals, namely arsenic (As), lead (Pb), cadmium (Cd), chromium (Cr) and copper (Cu). Their concentrations in water and sediments as well as in three fish species such as Labeo rohita (herbivorous), Wallago attu (carnivorous) and Heteropneustes fossilis (omnivorous) were recorded. During wet and dry seasons As, Pb, Cd, Cr, Cu concentrations in river water ranged from the ‘below detection level (BDL)’- 0.0019, 0.3702 - 0.4163, 0.0285 - 0.0294, 1.204 - 1.36, 0.0315 - 0.0807 ppm and 0.0016 - 0.0180, 0.1305 - 0.1889, 0.0297 - 0.0309, BDL, 0.0381 - 0.0543 ppm, respectively. There was no significant seasonal variation in As and Cu conc. in river water but Cr and Pb conc. were significantly higher during the wet season and Cd conc. was significantly higher during dry season. During the wet and dry seasons As, Pb, Cd, Cr, Cu conc. in river sediments ranged from 3.67 - 7.13, 21.58 - 64.96, 1.36 - 1.72, 1126.66 - 1199.46, 45.91 - 115.57 ppm and 5.10 - 8.88, 19.27 - 30.75, 1.39 - 1.48, 99.67 - 446.72, 68.98 - 442.78 ppm, respectively. There were no significant seasonal variations in As, Pb, Cd and Cu concentrations of river sediment but Cr concentration was significantly higher during the wet season. Among muscle, gill and gut tissues of three selected fish species, Pb showed the highest level of accumulation in gill tissues while As showed the lowest level of accumulation in muscle tissues in all three species. Pb, Cd and Cr concentrations in the river water were above WHO Guideline values while As and Cu concentrations were below WHO Guideline values. As, Pb, Cd, Cr and Cu concentrations in the river sediment were above the environmental protection agency’s threshold effect level. In all the three studied fish species, As conc. was below FAO guideline value. Pb, Cd and Cr conc. were higher than FAO guideline value in all three fish species and Cu conc. was above FAO guideline value in one species (H. fossilis). At least three heavy metal concentrations were above FAO guideline value in all three fish species. Therefore, all three fish species were not safe for human consumption. Bangladesh J.

Abstract:

The fatty acid composition of the muscle tissue of Wallagu attu found in Gangetic West Bengal, India was investigated to get an insight of its nutritional capacity. The fish muscle proved to be a rich source of both mono and poly unsaturated fatty acids. Of the saturated fatty acids Palmitic and Heneicosanoic acid is detected in considerable amount. Of the MUFA’s present Palmetoleic acid, Elaidic acid, Oleic acid and nervonic acid is found in good amount. Nutritionally important ω-6 PUFA’s like Linoleic acid and Arachidonic acid are found in the fish. EPA and DHA the two star ω-3 PUFA’s whose health benefits are beyond doubt are also detected in the fish. Wallagu attu is generally not farmed as it devours other fishes but considering its nutritional capacity and high market demands, its farming may prove beneficial for consumers and producers.
