A total of 216 fecal samples of companion cats from Dhaka city were collected. A questionnaire survey was conducted among the cat owners to collect various data on the companion cats viz. age, breed, food, clinical issues, behavior etc. Double centrifugal flotation technique was used to process the fecal samples. In total 70 fecal samples of cat were found to be infected with at least one helminth parasite. Hookworms showed the highest prevalence (9.26%) followed by Trichuris vulpis (7.41%), Dipylidium spp. (6.02%) and Toxocara cati (4.63%). Parasitic infections were prevalent among the cats aged one to two years old (71.43%). Local breed cats were more prone to parasitic infections (67.14%). Outdoor access (70%), irregular deworming (50%) and providing homemade food (70%) were significantly associated with high prevalence of parasitic infections (P < 0.05). The maximum helminth positive cats were found to have irregular bowel movement or constipation (22.86%) and sneezing (22.86%) (P=0.000). The maximum helminth infected cats showed aggression towards other animals (34.28%). Behaviors such as scratching furniture’s (17.14%) and excessive vocalization (15.71%) were also common among the infected cats. A total of 182 (84.26%) cat owners had idea about zoonosis whereas 34 (15.74%) were unaware of it. The owners who knew about zoonosis, their cats were mostly free of infection (93.15%). Pet owners’ alertness towards cats’ behavior, clinical symptoms, prophylactic measures and overall hygiene management may be operative to lower the possibility of zoonotic transmission of parasites.\u0000Bangladesh J.

Some water quality parameters (temperature, pH and transparency) were measured in two selected sites (Boidyerbazar ghat and Uddamganj) of the river. In this study, a total of 58 fish species were identified, which belong to nine orders, 26 families and 41 genera. Cypriniformes was the most dominant order contributing about 34.48% of the fish species diversity. A total of 30 species were considered as of Least Concern (LC) while ten species were Near Threatened (NT), seven species were Endangered (EN), six species were Vulnerable (VU), only one species Bagarius bagarius ranked as Critically Endangered (CE) and four species were not listed according to IUCN (2015). The highest number of fish species was observed in the rainy season while the lowest was in the summer. The ranges of water temperature, pH and turbidity values in the river were 21-32 C, 6.5-8.5 and 23-42 NTU, respectively. This study indicates that the fish species diversity of the Meghna River is likely declined gradually when compared with previous studies.\u0000Bangladesh J.

This study was evaluated the physicochemical features of water and their relationships in Sindphana Dam near Shirur Kasar, Breed district, Maharashtra state, India between January and December 2012. This study shows the water quality parameters were fluctuated during the summer, monsoon and winter seasons in Sindphana Dam. In this study, air temperature was positively related to water temperature, transparency and pH while it was negatively related to electric conductivity and dissolved oxygen (DO). The water temperature was positively related to air temperature, transparency and pH, while it was negatively related to electric conductivity and DO. Water transparency also negatively related to turbidity, electric conductivity, biochemical oxygen demand (BOD) and chemical oxygen demand (COD). Electric conductivity was positively related to turbidity, BOD and COD. The pH was negatively related to electric conductivity, DO, BOD and COD. The study indicated that the Sindphana Dam water quality parameters were acceptable limits for aquatic biota.\u0000Bangladesh J.

DDTs was extracted by QuEChERS method, cleaned-up by H2SO4 treatment and analyzed by GC with Electron Capture Detector. The calibration curves were linear over the range of the tested concentrations as shown by the fact that the correlation coefficients (r2) for the linearity range were 0.995-0.999. The detection limit was found to be 5ppb for DDTs and the quantification limit was 6.5ppb. Recoveries were found (70-130%); this is acceptable for fish samples according to standard methodology. The DDT and its metabolites were not detected in the liver of M. cavasius and C. punctatus. In this study, M. cavasius was found to contain detectable amount of residual targeted pesticides DDTs at 64.21 ppb in digestive tract, 75.23 ppb in gill, 119.82 ppb in gonad and 45.84 ppb in muscle. The C. punctatus residual targeted DDTs were at 8.42 ppb in digestive tract, 4.04 ppb in gill, 56.44 ppb in gonad and 23.15 ppb in muscle. However, this study shows the higher DDT and its metabolites were in the gonad of M. cavasius and C. punctatus.\u0000Bangladesh J.

Two markets were selected from Dhaka South City Corporation, Showari Ghat and Jatrabari fish market, and two from Dhaka North City Corporation, Karwan Bazar and Abdullahpur fish market. The investigation was carried out from November 2018 to October 2019. Questionnaire based survey, FGDs (Focus Group Discussion) and KIIs (Key Informant Interviews) were conducted to get quantitative and qualitative data for present study. A total number of 62 fishes and 6 crustacean species were recorded during the study period. Among all species, 39 freshwater, 10 marine and 13 exotic fishes were recorded. Infrastructure facilities were very poor for all four markets in the matter of hygiene and quality control. Fish shades were not enough, improper sanitation and drainage system indicates the possibilities of disease transmission and deteriorate fish quality. Electricity and water supplies were good but no system was present to determine the distillation of those supplied water. Thus, infrastructural condition of the markets does not support a hygienic condition for fish marketing to provide quality fish and fish byproducts. The study highlighted the need for national initiatives, awareness building, and law implementation for improving the wholesale markets infrastructure to a minimum standard so that fish trade could provide good quality to the people of Dhaka City\u0000Bangladesh J.

These ponds are connected to Baunia canal. Water samples were collected seasonally for water quality and zooplankton analyses. Except DO all other measured water quality parameters (pH, TDS, TSS, total ammonia-N, total nitrite-N, total nitrate-N, total phosphate, total sulphate, alkalinity and hardness) were found higher in water. A total of 10 heavy metals (Zn, Fe, Pb, Cd, Al, As, Cu, Na, Mn and Cr) were measured for determining its concentrations in waters in two seasons. A total of 10 zooplankton species were recorded at Kalshi during the study period and on an average, the density of zooplankton in dry season and in wet season were estimated to be 1386 indiv./L and 244 indiv./L respectively. On the other hand, a total of 19 zooplankton species were identified from Namapara water body and on an average, the density of zooplankton in dry season and in wet season were estimated to be 1760 indiv/L and 343 indiv./L respectively. Bacteriological analysis included the total plate count (TPC), total coliform (TC) and total faecal coliform (TFC) counts in waters, both in wet and dry seasons. In general, water qualities of the studied fish culture water bodies are highly deviated from the permissible standard levels of Environment conservation rules, 1997 and unsuitable for fish culture from fish health point of view. The measured high levels of metals in waters are likely to bioaccumulate in fish body. High abundance of bacterial flora in fish culture waters is also likely to be associated with fish health and may cause enteric diseases. Therefore, fish culture in these urban water bodies is likely pose potential health risks for human through consuming these fishes.\u0000Bangladesh J.
