Abstract:

Keting fish is a type of fish from freshwater which is usually used as a consumption fish or ornamental fish. There is a type of kein, namely from the species Mystus gulio (Hamilton, 1922). Mystus gulio ecosystem is disturbed due to land-use change activities in the river which causes the disturbance of the habitat of Mystus gulio. The purpose of this study is to analyze the long-weight relationship, growth pattern, and condition factors of Mystus gulio in downstream Gembong and Rejoso River. The method used in this study is to sample Mystus gulio from 3 stations on each river based on land use criteria. The research was carried out for 3 months, namely August, September and October 2023. The results of this study show that Mystus gulio caught in these two rivers all have a negative allometric growth pattern (b<3). The average value of the condition factor in these two rivers is 1 which indicates that the condition of Mystus gulio is good. The average growth of Mystus gulio caught in Gembong is relatively larger than Rejoso. The waters quality results of Gembong and Rejoso are still in optimal condition, except for Total Suspended Solid and Lead (Pb).

Abstract:

Three different species of tengra; Nuna tengra (Mystus gulio), Bazri tengra (Mystus tengara), Gholsha tengra (Mystus cavasius) were kept in freezing condition for 20 days to investigate the effect of freezing (-5°C) time on the nutrient composition (protein, lipid, moisture). The average weight of the sample was 46.5gm, 23.94gm, and 15.48gm for Nuna tengra, Gholsha tengra and Bazri tengra respectively. Samples were collected from Gollamari, Khulna. The amount of protein and lipid reduced while amount of moisture increased with prolongation of freezing time. The amount of moisture for Mystus tengara, Mystus cavasius, Mystus gulio increased from 76.12% to78.02%, 75.35% to 77.25%and 76.03% to 78.23% respectively. At fresh condition the protein content of Mystus tengara, Mystus cavasius, Mystus gulio were 16.26%, 15.52% and 14.80% and at the end of the experiment protein were 14.97%, 13.91% and 13.43%. At fresh condition the lipid content of Mystus tengara, Mystus cavasius, Mystus gulio were 6.15%, 5.98% and 6.20% and after twenty days of its freezing the observed lipid content were 4.9%, 5.37% and 4.86%. However, at the end of the study, no significant (p>0.5) difference was observed among different nutrient level due to increasing freezing time. DOI: http://dx.doi.org/10.3329/jsf.v8i1-2.14634 J.

Abstract:

Mystus gulio and Mystus cavasius are small indigenous fish species (SIFs) found throughout the year at the various stretches of the river Ganga and contribute significantly to the commercial fishery. The current study was conducted with a total of 609 specimens of M. gulio with a total length ranging from 84 to 190 mm and 377 specimens of M. cavasius with a total length ranging from 51 to 232 mm, collected from eight selected sites of lower stretches of the river Ganga between July 2018 and October 2019 to analyse their growth, mortality, and exploitation status. The sample specimens’ length-frequency distribution, primarily taken from bag nets and set barrier nets used in artisanal fisheries, was assessed using the FiSAT II programme. For M. gulio, the estimated asymptotic length (L∞), growth coefficient (K), and initial condition factor (t0) were 183.23 mm, 0.31 yr−1, and −0.486 years, and for M. cavasius, these values were 246.23 mm, 0.19 yr−1, and −0.302 years, respectively. The estimates for the total (Z), natural (M), and fishing (F) mortality rates were 1.78, 0.49, and 1.29 yr−1 for M. gulio and 0.68, 0.33, and 0.35 yr−1 for M. cavasius, respectively. Both M. gulio (May to July) and M. cavasius (June to August) experienced a single spawning peak. The estimated exploitation ratio (E) for M. gulio was 0.72, which is higher than the optimal level of exploitation (Eopt) and the maximum level of exploitation (Emax). On the other hand, the E value for M. cavasius was 0.52, which means that it was exploited at the right level. The fishing pressure was found to be slightly excessive for the current stocks of M. gulio, which should be considered for proper management of the fishery in the river Ganga. The present study, the first of its kind, highlights the stock status of these two commercially important species and the management measures taken to revive the stock along the lower stretches of the Ganga in India. The environmental parameters of the lower stretches of the river Ganga show favourable conditions for the optimum growth of M. gulio and M. cavasius.

Abstract:

The microplastics (MPs) are less than 5 mm in length. The freshwater organisms, including fish, can consume microplastics. Here, we investigate the presence of microplastics in Mystus gulio and Oreochromis niloticus fish species. The fishes were collected from Suthamalli, Thamirabarani River, Tirunelveli. We identified the collected fish at the species level, and fish gastrointestinal tracts were dissected and ground with mortar and pestle. Samples were filtered, and dried in sunlight. The presence of microplastic particles was observed by the Olympus (CH20i) microscope. We analyzed the morphological variation (fiber, fragment and bead) and different colored (white, red, blue, brown, black and green) microplastics in the gastrointestinal tract of both species. The both fish Mystus gulio and Oreochromis niloticus Hepatosomatic Index (HSI), Gastro-Somatic Index (GSI), Splenosomatic Index (SSI) and Hyperosmotic Index (NSI) were calculated. In this study, MPs present in the gut of Mystus gulio, 33.3% of fiber, 61.90% of fragment, and 4.76% of beads were found. In Oreochromis niloticus, 36.36% of fiber and 63.63% of fragment were found. The isolated fish gut MPs were characterized by ATR-FTIR. The analysis confirmed the presence of polymers like, polyethylene terephthalate (PET), polypropylene (PP), polyamide (Nylon), polystyrene (PS), polyvinyl chloride (PVC), and polyethylene (PE). Morphometric analysis further revealed that the highest degree of correlation was observed between the total length and the standard length for both fish species. This research provides proof that both fish species are contaminated by the MPs, the river ecosystem is contaminated by plastics.

Abstract:

The tengra fish (Mystus gulio) is an important commercial species found in the coastal regions of West Bengal, India and Bangladesh. M. gulio is an important species within its ecosystem and has significance in local fisheries. Its adaptability to both freshwater and brackish environments makes it a resilient species. This study investigated the hepatosomatic index (HSI), gonadosomatic index (GSI), and fecundity of M. gulio to better understand its reproductive biology. Specimens were collected monthly from the Meghna River estuary between February and June 2023. The GSI was found to be highest in August (9.95±0.15%), indicating the peak spawning season. The HSI showed an inverse relationship with GSI, being lowest in March. Fecundity ranged from 88,495 to 264,104 eggs, with a mean of 171,581±17,855. Fecundity was positively correlated with total length, body weight, and gonad weight. Statistical analysis revealed significant differences in GSI and HSI between sexes and age groups (virgin vs 1+ year). Regression models showed that fecundity was highly dependent on gonad weight (r2=0.809) compared to length (r2=0.047) and weight (r2=0.216). M. gulio is an important brackish water fish with good taste and nutritional value. While it is optimally exploited from the East Coast of India, its culture potential is being explored through polyculture experiments and research on seed production and farming techniques. These findings provide valuable insights into the reproductive dynamics of M. gulio and can inform management strategies for sustainable fisheries. However, further research is needed to fully understand the reproductive biology of this catfish across its range to inform sustainable management strategies.

Abstract:

The study was conducted for a period of twelve months from January to December 2006 to determine the gonadosomatic index (GSI) and fecundity of Mystus gulio. Total 370 of Mystus gulio were examined during the study period. The sex ratio (male:female) of the investigated fish was 1:1.22 and generally female was larger than male. The fish was found to have a wide spawning season (March to November) with a single spawning peak in July as indicated by the gonadosomatic index and ova diameter. Fecundity of the fish was ranged from 3,891 to 1,68,358 with an average of 32,909.49 during the period of study and was found to increase with the increase of body length and weight. The relationships between fecundity and total-length, body-weight, gonad-length and gonad-weight were found linear and statistically highly significant (p<0.05).DOI: http://dx.doi.org/10.3329/pa.v19i2.16957 Progress.

Abstract:

Detailed knowledge of food and feeding habits is essential for the thriving culture of a fish species. The present study analyses the food and feeding habits of an indigenous bagrid catfish, Mystus gulio, from Vembanad Lake, southern Kerala’s most extensive wetland system. The main objective is to check the feasibility of utilizing Mystus gulio as a bioremediation agent for kitchen waste recycling. From the Vembanad Lake, 779 specimens were sampled from fishery catches during July 2015 to June 2017. The gut contents of 318 specimens were analyzed to summarize the species’ diet components and food preferences. Gastro somatic index, relative length and fullness of gut, feeding intensity, food components, and index of preponderance for various food items were calculated. The results showed that the fish is an omnivorous bottom feeder, feeding mainly on fish offal, plant matter, filamentous algae, prawns, and polychaetes. The results points to the possibility of considering this species a bioremediation agent for recycling kitchen waste.

Abstract:

Due to increased industrialization in developing countries some of the toxic substances are being increased in day-to-day life. Living organisms need some trace amounts of metals like copper, manganese, zinc etc. but some of the non-essential toxic heavy metals are also accumulated in the body of living organisms which may cause damages to the immune organs of the organism. The present study investigated the impacts of sublethal dosage of inorganic Lead acetate on the hematological, biochemical and immunological responses of the brackish water fish Mystus gulio. The LC50 at 96 h was determined by the Probit method. The experiment was performed for 30 days of exposure of lead acetate (4 mg/l) to the fish Mystus gulio. After exposure to lead nitrate hematological (hemoglobin, RBC, WBC, PCV, neutrophil, eosinophil and platelet), biochemical (glucose, protein, albumin and globulin) and immunological (IgM) parameters were analyzed. A decrease was seen in the RBC count, hemoglobin, PCV, MCV, MCH, MCHC, protein, albumin and globulin whereas an increase was seen in WBC count, neutrophils, eosinophils, ESR, platelet count, glucose and Immunoglobulin (IgM).

Abstract:

The present study was conducted to detect a correlation between Pb content in sediment and muscle of fish (Mystus gulio Ham. - Buch.) and downstream stretches (three study sites) of the of the river Hooghly, West Bengal, India. The study sites were selected at Batanagar (Bt), Budge Budge (Bg) and Birlapur (Br) sites. The samples viz. sediment and muscle of fish were collected and estimated by using atomic absorption spectrophotometer. The Pearson correlation coefficient analysis was performed to know the association between these sites and sediment as well as muscle during pre-monsoon season. The study sites observed both significant positive (P is less than 0.05) and negative correlation with sediment of river Hooghly at downstream while significant (Pis less than0.05) positive correlation was observed between the study sites and muscle of the fish specimen (Mystus gulio). The findings pose the risk of accumulation may be lower in fish muscle due to positive correlation, but negative correlation may lead to harmful impact in the study site for sediment. In future, this study may be beneficial to determine the water and sediment quality status in different stations of river Hooghly as well as other metals content in different fish species.

Abstract:

Members of the family of Trichodinae are best known as ectoparasites that infect diverse range of fishes. Infection from this parasite causes massive pathological development and leading to the mortality of host fishes. A preliminary study among different regions of Hooghly Estuarine fishes present in South 24 Parganas, West Bengal found Trichodinid cilliophorans infecting the gills of Mystus gulio (Hamilton, 1822) (Bagridae) that causes damage in the gill epithelium of many host fishes. Description based on wet silver nitrate impregnation method that is performed with compound microscopic study Olympus BX43, attached with digital camera Olympus- DP23. During the course of surveillance Trichodinid Cilliophorans were found Medium size, flattened, disc shaped body, cup shaped adhesive disc, surrounded by finely striated distinct and broad band-like border membrane. Denticulated ring containing 22-24 robust denticles with sickle shaped blade and 7–9 radial pins on each denticle were observed. This is identified as Trichodina acuta Lom, 1961 based on this study and described for the first time from the Hooghly Estuarine fish Mystus gulio. The observation finds that seasonal variations affect the count of this ectoparasite in the host body.

Abstract:

Food and feeding habits are important things in bioecological of fish. This study provides an understanding of the feeding habits and intensity of the M. gulio, by analyzing its food composition, relative gut length (RGL) and gastro-somatic index (GaSI). Fish specimens were caught with a gill net and fishing rod in an area of Cianjur estuaries during a period of one year from October 2021 to September 2022. The analysis of 452 fish samples shows that the relative gut length (RGL) values revealed the feeding habit of M. gulio as carni-omnivorous. The GaSI value was used to determine feeding intensity and was found to be highest in November, at Cidamar estuary, and in the second size group (7.1-10 cm). These results provide new knowledge on this fish species’ feeding habit and intensity, which also helps understand the fish adaptation and conservation in the study area.

Abstract:

The world’s largest mangrove, Sundarbans, Bangladesh, is the habitat of the euryhaline catfish Nona Tengra (Mystus gulio). This study aimed to assess the stock status of M. gulio and provide reference points for sustainable fisheries’ management. One-year length–frequency (LF) data were collected from the Sundarbans region of Bangladesh and analyzed using the Length-Based Bayesian Biomass (LBB) method and the Length-Based Spawning Potential Ratio (LBSPR) model. The findings showed healthy biomass (B/BMSY = 1.2), with 57% of the wild stock of this species being harvested (B/B0 = 0.43). The calculated fishing mortality ratio indicated the underfishing conditions (F/M = 0.9). Safe exploitation (E = 0.46) was depicted, as E was smaller than the permitted level of 0.5. The value of capture length (Lc = 12.8 cm) was larger than the optimum capture length (Lc_opt = 10.0 cm) and the optimum length for maximum yield per recruit (Lopt = 12.0 cm) and larger than the maturity length (Lm = 9.16 cm), indicating the capture of mature individuals. The calculated Spawning Potential Ratio (SPR = 48%) was higher than the target reference points (SPR = 40%). This research evaluated the sustainable stock status. Although the margin between Lc_opt and Lm is very narrow, setting the minimum capture size at Lopt would be a conservative buffer to ensure long-term sustainability. The recommended minimum harvest size is 12 cm for M. gulio. Current fishing gear selectivity can ensure the sustainability of M. gulio in Sundarbans, Bangladesh; however, maintaining current fishing practice through careful management is suggested. Further assessments with length-based and other low-data methods should be conducted to refine exploitation estimates and trends.

Abstract:

Objective: Nanotechnology an advanced tool to synthesis atomic level particles. Increased application of silver nanoparticles results in the bioaccumulation of these particles in the environment. The biological effect of the green synthesized silver nanoparticles on the fresh water cat fish ws studied in the present study.Methods: Asystasia gangetica leaf extract was used to synthesize silver nanoparticles, the particles were characterized by scanning electron microscopy. Fifteen days after the introduction of fishes into the medium containing AgNPs, the fishes were sacrificed and the tissues were processed for biochemical and histological studies. Na+-K+-ATPase was estimated using LeBel method. Estimation of carbohydrate was done by the Phenol-sulphuric acid method. Total protein was estimated using Lowry’s method, Sulpho-Vanilline method was used to estimate the total lipids.Results: The results observed in the present study reveals a marked difference in the level of carbohydrate in the muscle tissue from 48.338±0.320 to 22.747±1.837 µg/100 mg wet tissue followed by gills and liver with 41.21% and 25.48% decrease. Total protein content was decreased from 649.094±1.429 to 491.56±0.925 µg/mg wet tissues. The drastic increase in the total lipids was observed in liver tissue of treated fishes from 0.240±0.004 to 0.408±0.005 mg/gm wet tissue. Na+-K+-ATPase activity of liver tissue increased from 0.153±0.001 to 0.225±0.003 in the liver tissue of treated fishes, followed by muscles and gills with 33.61% and 35% of the increase in the activity. Marked changes in the structure of gills with degenerated primary gill lamellae, necrosis, hyperplasia and fused primary lamellae were evident in experimental group. Necrosis, vacuolization, disintegrated nucleus and blood sinusoids were observed in liver tissues. Disintegration of myofibrils was evident in AgNP treated group of fishes.Conclusion: The plant-mediated synthesized AgNPs shows a potential toxic effect on all the tissues studied; changes were observed in the normal architecture of tissues as well as in the biochemical parameters.

Abstract:

Background: Mystus albolineatus Roberts, 1994, is an endemic bagrid catfish species distributed across Cambodia, Thailand, and Vietnam. Despite its ecological and taxonomic significance, the complete mitochondrial genome of this species has not been widely reported, limiting our understanding of its genetic composition and evolutionary relationships. This study aimed to sequence, annotate the complete mitogenome of M. albolineatus, and determine its phylogenetic position within the Bagridae family. Methods: Muscle tissue from M. albolineatus was collected in Can Tho Province, Vietnam. Genomic DNA was extracted using a commercial purification kit, and sequencing was performed on an Illumina MiSeq platform. The obtained reads were assembled de novo using NOVOPlasty, and gene annotation was conducted using the MITOS2. Phylogenetic analysis was performed using the maximum likelihood method based on 13 protein-coding genes from 24 ingroups of Bagridae species and two outgroups of Cyprinidae. Results: The complete mitogenome of M. albolineatus was 16,574 bp in length and encoded 37 genes, including 13 protein-coding genes, 22 transfer RNA genes, and two ribosomal RNA genes. The overall GC content was 41.1%. Phylogenetic analysis confirmed that M. albolineatus is closely related to Mystus gulio and Mystus cavasius and forms a distinct clade within Mystus. Conclusions: This study provides the first complete mitochondrial genome of M. albolineatus and contributes to the growing catfish mitogenome database. The findings enhance our understanding of its phylogenetic relationships and serve as a foundation for future research in taxonomy, conservation genetics, and evolutionary biology.

Abstract:

During a survey on species diversity of trichodinid ciliates from freshwater fishes in the Beel Dakatia located in Khulna District of Bangladesh, a new species of trichodinid ciliate was identified from the gills of Long Whiskers Catfish, Mystus gulio. This ciliate is described here as new species based on distinctness in a combination of morphological characters. The species differs morphologically from its congeners by its relatively small body diameter, with white porcelain Chinese soup spoons-shaped denticle and the argentophobic central area of adhesive disc looks like a centrally located glistening, undivided, almost spotless white circle, surrounded by dark and narrow wrinkle free perimeter and some other measurements.

Abstract:

Study was conducted to determine the heavy metal concentration in 5 freshwater fishes Heteropneustes fossilis, Clarias batrachus, Anabus testudineus, Oreochromis niloticus, and Mystus gulio during autumn and winter. Most widely eaten five freshwater fish species were selected for this purpose. These fish species were Among the heavy metals estimated in this study (Cd, Cr, Pb, Cu, Zn) the Cd, Cu, Zn were within the acceptable level but Cr and Pb concentration was above the maximum allowable limit. The Cd, Cr, Pb concentration in the fish muscle was higher in winter as compared to that of autumn but the Cu and Zn concentration was higher in autumn when compared to that of winter. Result of the present research indicates that the heavy metal concentration in fish muscle significantly varies with season. Some heavy metal were within the acceptable level in autumn season but above the maximum allowable limit in winter season. In H. fossilis, C. batrachus, and O. niloticus, heavy metal concentration was within the acceptable level but in A. testudineus and M. gulio heavy metal concentration was above the maximum allowable limit. So heavy metal concentration varied with season as well as with species of fish.

Abstract:

Mystus gulio is a local fish that can open up opportunities for the community. Pollution causes water quality to decrease. Fish are an important indicator in the aquatic environment, Histological analysis can be said to have a function as a natural biological sign to determine the health condition of fish which can be seen from changes in tissue structure in organs exposed to pollutants. Organs that’s vulnerable to water pollution is kidneys. Kidney tissue is susceptible to damage because kidneys function as a means of filtration and excretion, The method used in this research is descriptive method. Fish were caught from river than dissected to remove the kidneys for histopathological analysis using the HE method, analyzed using the scoring method. The results obtained in both rivers were that fish kidneys caught in the Gembong River were categorized as moderately damaged, while fish kidneys caught from the Rejoso River were categorized as lightly damaged. This is in line with the results of the heavy metal lead from both rivers. Where the yield of lead in fish kidneys caught from the Gembong is on average higher than the yield from fish kidneys caught from the Rejoso.

Abstract:

Nijhum Dweep National Park lacks a detailed inventory of aquatic fauna including fish. This study reported the diversity and abundance of fish along with their conservation status from the surrounding waters of the national park to fill the knowledge gap. Fish samples were collected randomly from 16 spots of surrounding water of the park between October 2017 and March 2018. There were 47 fish species recorded belonging to 10 orders, 27 families and 44 genera. Odontamblyopus rubicundus was the dominant fish species that comprised 20.24% of the total catch, followed by Rhinomugil corsula (15.54%), Mystus gulio (12.03%) and Eleutheronema tetradactylum (9.92%). One nationally Endangered fish species (Clupisoma garua) and three Vulnerable fish species (Gudusia chapra, Sicamugil cascasia and Wallago attu) were recorded. Fish diversity of the park was rich but exceeding extraction rate, huge disposal of by catch, and presence of exotic omnivorous fish species was disconcerting that require monitoring and further studies.

Abstract:

The catching efficiency of traditional traps: Ayunan and Tamba were tested in Sungai Batang River, South Kalimantan of Indonesia. Trials consisted of 320-trap hauls/type using 1-day submersion time of 24 hr. The baited traps sampling accounted for 82 specimens assigned to 5 species of 5 families. There was a large variability in number of catch between prawns and fish species collected (T=2.318, P<0.05). The prawns catch was represented by only the species Macrobrachium rossenbergii with total of 53 and 1,015 g weight. The prawns weight of Tamba was significantly higher than that of Ayunan (T=3.453, P<0.01).The fish catch composed of Mystus gulio 79%, Osteochilus hasselti 10%, Hypostomus plecostomus 7%, and Macrognathus aculeatus 3%, with total weight ranged from 35 to 560 g. A clear difference was found in catching efficiency. Comparative fishing trials showed that Tamba collected specimens were 1.8 times higher than Ayunan (T=2.223, P<0.05). Catch per unit effort for Tamba ranged from 58.13 to 80.00, and for Ayunan ranged from 5.31 to 7.19. The gear modifications and various treatments (e.g. bait odor, light) are necessary to be taken to increase their relative catching efficiency.

Abstract:

ABSTRACT Mystus vittatus, an indigenous fish species of West-Bengal are economically important due to its delicious taste. The ovarian histo-morphology and its annual changes and the spawning periodicity of this catfish were studied collected monthly in one year period of November, 2012 to October, 2013. The fecundity, gonado-somatic index, different stages of ovarian development (nucleus changes, oocyte diameter and formation of yolk vesicles, yolk granules and lipid droplets through histological observation) of M. vittatus were also observed in this article. By gross morphology and its seasonal changes of ovary especially on the changes in cell structure of this species, five maturity stages were distinguished to categorize the developing ovary: immature, mature, early ripening, ripe and spent. Our investigation has revealed that gonado-somatic index (GSI) in M. vittatus began to increase in March and peaked in July then declined sharply in September-October. This cat fish   attained sexual maturity at 10-11 cm in length, 10-12 g in weight which was confirmed at the peaks of gonado-somatic index (GSI) and fecundity. The fecundity of Mystus vittatus has shown highly significant correlation with body length, body weight and ovary weight. Keywords- Mystus vittatus, gonado-somatic index, fecundity.

Abstract:

The aim of the study was to identify the frequencies of micro nucleations (MN) and nuclear abnormalities (NAs) in the peripheral erythrocytes of fish (Mystus gulio Ham. – Buch.) inhabiting downstream at three locations of river Hooghly, West Bengal, India. The study area mainly consists of three sampling sites, viz., Budge Budge (Bg), Batanagar (Bt) and Birlapur (Br), which were selected. The present study is a first-time endeavour to know the environmental status with particular reference to water pollution through genetic biomonitoring in the Hooghly River of a middle stretch from Batanagar to Birlapur near Diamond-Harbour coastal zone in the inhabiting fish (M. julio). The genotoxic effect, especially induction of MN and NAs in the peripheral erythrocytes, was done on the studied fish. In the case of MN frequencies (%), the values for sites Bt1 & Bt2, Bg1 & Bg2 and Br1 & Br2 were observed 1.92±0.10, 1.40±0.24 and 2.00±0.13, respectively were increased during pre-monsoon season compared to post-monsoon season (1.83 ±0.15, 1.36 ±0.04 and 1.91 ±0.12, respectively). The frequencies (%) of NA, such as lobed nuclei (LN), blebbed nuclei (BLN), notch nuclei (NN), bi-nuclei (BN), dumble-shaped nuclei (DSN), retracted nuclei (RN), nuclear caryolysis (NC), and fragmented nuclei (FN) values, were also observed in the fishes of three study sites. In the case of NA frequencies (%), the values for sites Bt1&Bt2, Bg1&Bg2 and Br1&Br2 were observed higher for BLN (1.54±0.09, 1.14±0.07 and 1.77±0.10, respectively), BN (1.09±0.04, 0.85±0.21 and 1.32±0.06, respectively), NN (1.02±0.09, 0.61±0.16 and 1.18±0.06, respectively), LN (1.86±0.08, 1.22±0.07 and 2.12±0.11, respectively), DSN (2.22±0.22, 1.69±0.08 and 2.56±0.11, respectively), RN (2.33±0.15, 1.82±0.13 and 2.73±0.05, respectively), FN (2.20±0.10, 1.72±0.08 and 2.56±0.13, respectively) and NC (3.01±0.06, 2.72±0.11 and 3.32±0.08, respectively) during pre-monsoon season when compared to post-monsoon season (BLN = 1.50 ±0.07, 1.06 ±0.03 and 1.73 ±0.07; BN = 0.83 ±0.11, 0.62 ±0.11 and 1.18 ±0.06; NN = 0.77 ±0.15, 0.43 ±0.11 and 1.05 ±0.03; LN = 1.42 ±0.06, 1.14 ±0.06 and 2.06 ±0.08; DSN = 1.76 ±0.06, 1.34 ±0.05 and 2.36±0.08; RN = 1.68 ±0.08, 1.30 ±0.06 and 2.31 ±0.08; FN = 1.59 ±0.08, 1.18 ±0.04 and 2.46±0.11 and NC = 2.58 ±0.53, 2.37 ±0.43 and 3.18 ±0.09, respectively). This study provides an important impact of mutagenic risk on the fish specimen, which may vanish due to the long-term effect of genotoxins or a combination of other pollutants. This specimen may show an alarming impact of water pollution, and this study is suggested for future study with other fish species to know the risk of vulnerability of mutation.
