An experiment was conducted to determine the heavy metal status in fruits and roots of brinjal plant cultivated in soil mixed with wastes at Environmental Science Field Laboratory, Bangladesh Agriculture University, Mymensingh. Two brinajl varieties of BARI namely BARI–1 and BARI–4 and three treatments viz. T0: control soil, T1: Municipal waste and T2: Industrial wastes were used for the present study. The data were collected on Cu, Zn, Pb and Fe of both fruits and roots of the brinjal plants. The data were analyzed by Atomic Absorption Spectrophotometer (AAS). The two factors experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Results revealed that the initial contents of Cu, Zn, Pb and Fe were higher in industrial waste mixed soil as compared to municipal waste and control soil. In contrast, the incidence of heavy metals in fruits and roots were tolerable range in normal and municipal waste mixed soil while industrial waste mixed soil showed highest values. This study also showed that the industrial waste treated plants of BARI–1 uptaked the more Cu and Zn content (16.12 and 21.39 mg/kg, respectively) in roots while plants of BARI–4 gave the more Pb and Fe content (0.363 and 365.70 mg/kg, respectively) in roots compared other interaction treatments. However, without waste treated or normal soil showed lowest effect on the incidence of heavy metal but municipal waste obtained the moderate effect. This result revealed that the both control and municipal waste treated soil may be acceptable for the cultivation of BARI brinjal in Bangladesh condition. This study also suggested that the industrial waste treated soil may not suitable for the vegetable cultivation might be due to the higher incidence of heavy metal in fruits and roots.Progressive Agriculture 27 (4): 453-465, 2016

Pabdah catfish, Ompokpabdawas collected from the Old Brahmaputra river and successfully induced to breed by injecting pituitary gland extract to evaluate spawning performances and developmental stages under a photo microscope from February 2018 to August 2018. In this study, absolute fecundity of the O. pabdafemales varied from 6,676 to 20,410 eggs per fish. The GSI value of male and female was lower during September and gradually attained its maximum level in June with the highest average value 6.75±0.2 and 1.053±0.2 in female and male, respectively. The average fertilization and hatching rate of eggs were found 78.67±1.33% and 70.21±0.73%, respectively at 24.5±1.0°C. Fertilized eggs were brownish in color, very transparent and adhesive in nature with 1.0 to 1.2 mm in diameter. Cleavage stages were completed at 1.50 h of post fertilization and it eventually took 23.00 h for hatching. Larva was appeared with prominent three pairs of barbells after 12.00 h of hatching. It took 3 d post hatching to absorb their yolk sac and feeding exogenously. The present work supplemented to the deficient information on detailed spawning and developmental biology of O. pabdain order to save this species from extinction. Asian J. Med. Biol. Res.

Climate change is a contemporary global threat to the whole world especially in the coastal area like Bangladesh. Bangladesh is extremely vulnerable to climate change impacts because of its geographical location. This research is an attempt to assess the impacts of climate change on fishersʹ livelihood of a selected climate hotspot zone Munshiganj. In the study area, the average sex ratios of male and female were 56.67% and 43.33%, respectively and their religion ratio were Islam 45% and Hindu 55%. There was 60% nuclear family and 40% joint family. About 86.4% house was tin-shed and drinking water source was only tube well. In Munshiganj, 11% fishers were illiterate, 27% had primary, 38% had secondary, 16% had higher secondary and 8% had bachelor. Most of the people about 59% were depended on Upazila Health Complex for their health issues. Highest percentage of fishers about 40% had an annual income of 20,001 to 24,000 BDT. About 62.7% fishers were agreed with the statements: reduce fish production, damage fishing ground, blockage of fish migration road, damage biodiversity, increasing temperature, enhance soil erosion, reduce rainfall, siltation, water flow, storm frequency, changing spawning season, decrease fish production, extinction fish species. In study area, women and children are affected severely i.e. malnutrition, education, treatment, early marriage etc. The present study clearly indicates that there are visible changes in livelihood condition of fishers‟ in the study areas of Munshiganj.
