This study based on the morphological features of the basic chromosome numbers and numerical characterization of the karyotypes using total chromosome length (TCL), arm ratio and total fraction frequency. Outcome of BARI Khesari-2 is more effective than BARI Khesari-3 on the basis of mitotic index, nuclear volume and interphase chromosome volume. Whereas, mitotic index directly relevant to cell division; when MI high than cell division rate will be high. The two varieties (BARI Khesari-2 and BARI Khesari-3) were found to possess 2n = 14 chromosomes. Karyotype analysis is an essential tool for studying the genetic constitution of any organism. In this investigation, we found the karyotype formula of BARI Khesari-2 is 7L 4m + 2sm + 1st and BARI Khesari-3 is 7L 2m +3sm + 2st. Chromosome morphology showed a variation in the chromosome length, chromosome structure and centromere position of the accessions. Presence of sub-terminal chromosome in both varieties shows asymmetric karyotype which indicates advanceness. The variation in L. sativus may be regarded as having evolution and adaptive significance. J.

Nowadays, this wetland is increasingly impacted by climate change, which poses significant challenges to fish production and sustainability. The primary data were collected through a face-to-face questionnaire survey (n = 150) with fishers, focus group discussion (n =15), and key informant interviews (n = 10). The majority of the fishers were middle-aged group (31-50 year), whereas 41% had primary level (schooling year 5) of education and 48% were highly experienced fishermen (≤16 years). Stakeholder perceptions of human activities, including overfishing (52%), discard of non-target species (23%), use of destructive fishing gear (67%), beel drying (47%), habitat destruction (48%), water pollution (23%), migration route changes (30%) and agricultural intensification (45%), have been identified to reduce fish production. Additionally, the study revealed that climate change impacts the ecosystem, including temperature fluctuation (57%), erratic rainfall (49%), flood and flash flood (37%), drought (17%), and siltation in beel (37%). Stakeholders perceived these impacts to have significant negative effects on aquatic biodiversity, particularly in terms of habitat destruction and water quality degradation. This study proposes potential solutions to mitigate the impacts of climate changes and man-made factors associated with fish production reduction in the region, such as improved water management practices, diversification of fish species, and the use of climate-resilient fisheries management. Community engagement and government support are highlighted as crucial factors to address the impacts of climate change on fish production in Hakaluki Haor. The findings of this study have important implications for the development of effective management strategies for ensuring sustainable livelihoods for fishers. J.

The production of this crop in open field is constrained by major pests like fruit borer, yellow striped armyworm and caterpillar. A pest exclusion net (PEN) experiment was carried out to assess the performance of seven varieties of tomato through growth, yield and pest occurrence. The two-factor experiment was carried out in randomized complete block design (RCBD) with three conditions viz. under net without pesticide, no net with pesticide, no net without pesticide and three replications. Data were analyzed with MSTAT-Cv. 2.1 software package and means were separated by Duncan’s multiple range test (DMRT) at 1% level of significance. The result revealed that crop under PEN had maximum plant height (98.47±1.02 cm), inflorescence number per plant (20.34±0.06), open flowers number per plant (69.34±2.02), fruit number per plant (43.12±0.03), individual fruit weight (49.70±0.02 g), gross yield (50.76±1.06 tons/ha) whereas no net with or without pesticide condition produced the minimum above traits. However, most of the parameters showed decreasing trend under no net condition except pest incidence. This study shows that the use of PEN protect tomato against pests, increases growth and yield which can be considered as a viable technology for tomato production by marginal farmers of Bangladesh.\u0000J Bio-Sci. 30(1): 21-32, 2022 (June)","PeriodicalId":90580,"journal":{"name":"Journal of bio-science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49323161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Length and weight increment was recorded for the growth study and gonado-somatic index (GSI) with fecundity was estimated for the assessment of reproductive activity. During the study a significant length and weight increment was observed (p<0.05). Monthly mean total length (TL) ranged 11.76 to 22.47 cm, fork length (FL) was 10.02 to 19.12 cm, standard length (SL) was 8.87 to 16.83 cm and body weight (BW) was 19.89 to 167.81g. Both the length-length relationship (LLR) and length-weight relationship (LWR) showed a positive allometric growth pattern of the fish and the relationships were TL = 1.1759 FL - 0.035, TL = 1.338 SL - 0.0002, FL = 1.0988 SL + 0.6557 and BW = 0.0051TL 3.347. Gonadal observation showed that the fish initiated sexuality in the month of April and was fully matured in the month of May. During the study male female ratio was significantly different from the 1:1 ratio (χ2 = 3.84, p<0.05) and the overall male to female sex ratio was 1:1.42. The gonado-somatic index (GSI) was ranged from 3.72 to 32.39 and showed significant monthly fluctuations (p<0.05). A sharp decline of GSI during May and June indicates the peak spawning of B. gonionotus in the study site. During the study the fecundity of the fish was ranged from 46145 to 353969 and the highest fecundity was recorded in the months of May. The findings of the present study would be helpful for the sustainable management of B. gonionotus in the freshwater ecosystem of Bangladesh and elsewhere.\u0000J Bio-Sci. 30(1): 101-114, 2022 (June)","PeriodicalId":90580,"journal":{"name":"Journal of bio-science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43021712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results showed that TL in the untreated (C) and T1 group of fishes differed significantly (p<0.05) even though the overall effect of the hormone did not influence TL of the fishes under study (p = 0.085). A similar result was observed for TW, but the overall impact of 17-αMT on TW of H. fossilis was highly significant one (p<0.001), indicating that the TW was increased much more than the TL due to the hormone treatment in the experimental fishes. Growth performances of the fishes in terms of their gains in TL and TW due to the hormone treatment and over a rearing period of four months from March to June showed that compared to the control groups, all three treatment groups increased in both the morphometric parameters in H. fossilis. The increases in TW were more drastic than the corresponding increases in TL. Notably, the hormone treatments did not affect the survival of the experiment fishes under study. Histopathological changes in the intestine of T2 fishes were characterized by hemorrhage and degeneration of villi, whereas hemorrhage, degeneration of serosa and rapture of villi were remarkable in T3 group. Enlarged glomeruli, lots of vacuoles, disorganization of renal tubules and necrosis were observed in T2 whereas the T3 group was characterized by vacuoles, disorganization of tubules, enlarging glomeruli and wider tubular lumen. Since the present results clearly demonstrated that 17 α-MT treatments enhanced the total length and weight as well as growth performance of H. fossilis, carefully designed experiments with appropriate doses of the hormone in fish feed would be beneficial for the commercial production and conservation of this popular catfish in the country.\u0000J Bio-Sci. 30(1): 131-141, 2022 (June)","PeriodicalId":90580,"journal":{"name":"Journal of bio-science","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69504191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
