Fish samples were collected directly from the local fishermen and the fish landing station of Saint Martin’s Island, Bay of Bengal on a regular monthly basis. A total of 448 individuals of parasites were collected of which nine species of parasites were identified including three crustaceans, four nematodes, one pentastomida, and one acanthocephala. The nematode Procamallanus longus had the highest prevalence (50%) and intensity (10.33) compared with the other parasites. The prevalence and intensity of parasites were slightly higher in female fish (55%, 35) than in male fish (50%, 20). The stomach and liver were the most favorable infection sites (53.33%).

The prevalence of helminths was 88% (44/50) and intensity was 34.73 (1528 parasites from 44 hosts). The study revealed that the rodents were infected with eight species of parasites (one trematode, four cestodes and three nematodes) which were collected from gastrointestinal tract and liver of the hosts. Of the helminths, the dominant parasites were Echinostoma cinetorchis (36.52%) followed by Heterakis spumosa (31.74%), Hymenolepis nana (7.26%), Syphacia obvelata (7.13%), Hydatigera taeniaeformis (6.68%), Oesophagostomum eurycephalum (5.04%), Hymenolepis diminuta (3.01%) and Hymenolepis sp. (2.62%). Domestic rats showed the highest prevalence of infestation (90%) compared to paddy field rats (85%), whereas the intensity was lower (30.30 ± 10.53) in domestic rats than in the paddy field rats (41.77 ± 12.79). Peak prevalence was observed in males but intensity was found higher in female host. Occurrence of double infection was higher in domestic rats (53.33%). Intestine was the favorite niche compared to other organs. The highest prevalence was observed in winter and spring and the intensity was the highest in autumn in domestic rat, whereas in paddy field rat, the highest prevalence was observed in autumn and spring, the intensity was also the highest in spring. In both the hosts, intermediate length groups and highest weight groups were more vulnerable to infection.

Altogether seven species of ectoparasites namely Anaticola crassicornis, Lipeurus caponis, Goniocotes hologaster, Menopon gallinae, Menacanthus stramineus, Holomenopon leucpxanthum and Dermanyssus gallinae were observed and identified. L. caponis showed the highest prevalence both in male and female (100%). Mean intensity of A. crassicornis in female ducks was the highest (14.5 ± 2.36) followed by L. caponis (12.5 ± 3.21). The lowest mean intensity was of G. hologaster (2.5 ± 1.41) in male ducks. Prevalence of D. gallinae was higher in male (62.5%) than in female (40%).

For this 60 C. livia were selected from five locations to assess the degree of pollution by heavy metals in pigeon. Significant differences in heavy metal concentrations were observed among different tissues, but not among the locations. The ranges of the measured concentrations (?g/g dry weight) in the tissues of C. livia were as follows: arsenic: (0.010.04), (0.020.04), (0.020.08), (0.020.04) and (0.030.07); lead: (0.210.56), (0.071.64), (0.621.97), (0.410.79) and (1.475.75); cadmium: (0.01-0.05), (0.130.97), (0.531.85), (0.32 0.78) and (0.222.41); chromium: (0.251.93), (1.185.90), (1.594.40), (1.151.65) and (1.388.36); zinc: (73.22256.56), (95.62130.75), (19.8767.18), (108.99124.77) and (159.80280.76); copper: (3.447...

Although there is difficulty in identifying accurately goatfish solely on the basis of morphology, U. vittatus and U. supravittatus were confirmed by both using morphological characters and DNA barcoding cytochrome oxidase I subunit (COI) approach for the first time in St. Martin’s Island, Bay of Bengal, Bangladesh. Increased number of species of the genus Upeneus was found in Bangladesh from 3 to 5 and extended the distribution range. Asiat. Soc. Bangladesh, Sci. 45(2): 161-173, December 2019
