Utilization of cuttlebone by aquafarmers at Visakhapatnam

Cephalopods represent an important group of molluscs and form an important component of the exploited marine fishery resources of the state. Cephalopods include squids, cuttlefishes and octopuses

Antagonistic activity of cellular components of Pseudomonas species against Aeromonas hydrophila

Antagonistic effects of Pseudomonas fluorescens, P. aeruginosa and P. putida were studied against 12 strains of Aeromonas hydrophila (Ah1–Ah12). Four different fractions of cellular component (i.e. whole cell product, heat killed whole cell product, intra cellular product and extra cellular product) of all Pseudomonas species were equally effective in reducing growth of A. hydrophila strains, as measured by the zone of inhibition in an in vitro sensitivity test and have potential action against A. hydrophila infection in fishes

Does minimizing seabed contact alleviate the impacts of bottom trawling? an experimental study on bycatch from North-Western Bay of Bengal

In light of the ecological concerns associated with bottom trawling in tropical multispecies fisheries, an attempt was undertaken to implement operational modifications in experimental trawling practices aimed at reducing bottom contact. This endeavour was pursued to investigate the resulting effects on bycatch biomass and diversity along the north-western Bay of Bengal. The average total catch rate and bycatch rate in 66 hauls from January 2017 to December 2019 were 35.46 kg/h and 9.70 kg/h respectively. Bycatch biomass was mainly contributed by Teleostei (77.90%), of which the dominant species was Equuilites lineolatus. Temporal variations in bycatch composition were recorded, and average seasonal dissimilarity ranged between 35.03% and 59.61%. Juvenile percentages varied among six commercial species from 1.42 to 28.0, and their occurrences were related to their peak spawning seasons. The trophic index of bycatch calculated was 3.65. Species diversity and richness in bycatch were higher during post-monsoon and summer seasons. Biomass and abundance plots indicated the bycatch fauna to be relatively unstressed during most seasons. Trawling marginally above the bottom had improved ecological outcomes; as evident from the decreased proportion of bycatch to total trawl catch, reduced growth overfishing from lower juvenile proportions and within optima for various diversity indicators

Bone metastasis

Rectal cancers may rarely metastasize in bone and when it occurs, is usually preceded by lung and/or liver metastasis. However, whether it may ever bypasses other organs, particularly lung and liver and metastasizes directly to bone or not, is debatable. Some authors have described the presence of isolated bone metastasis from colo-rectal cancers, whereas others have questioned its′ existence in the absence of lung or liver metastasis. A case of isolated bone metastasis from rectal cancer in the absence of lung or liver metastasis is reported here

Trace elements exposure through the dietary intake of fruits and vegetables collected from a divisional city of Bangladesh: Human health implications

Background: Dietary exposure is the main source of bioaccumulation of trace elements through contaminated fruits and vegetables, which are rich sources of vitamins and minerals, but also toxic elements, which harm our health and well-being. Objectives: This study focused on human health nutrition and risks associated with the cancer-causing and non-cancerous trace elements in commonly available winter fruits and vegetables collected from Mymensingh divisional city markets. Methods: Six locally available fruits (viz. pineapple, guava, hog plum, water chestnut, banana, Indian olive) and six seasonal vegetables (viz. red amaranth, radish leaves, brinjal, bottle gourd, radish, and carrot) were collected. The atomic absorption spectrophotometer was used to determine the contents of Zn, Fe, Mn, Cu, Pb, Cr, and Cd. Target Hazard Quotient (THQ), Hazard Index (HI), and Cumulative Incremental Lifetime Cancer Risk (∑ILCR) were calculated to estimate non-cancer and cancer health risks. Results: All trace element contents were higher in vegetables than in fruits except Cu. Chromium contents were below the detectable limit for all fruits and vegetables. The highest amounts of Zn (10.54 µg g−1 fresh wt.), Fe (68.75 µg g−1 fresh wt.) and Mn (55.65 µg g−1 fresh wt.) were found in radish leaves. On the other hand, the maximum amounts of Pb (0.388 µg g−1 fresh wt.) and Cd (0.180 µg g−1 fresh wt.) were found in red amaranth, while the highest content of Cu (5.67 µg g−1 fresh wt.) was determined from banana. The calculated HI was <1 in every case except red amaranth suggesting none of the fruit and other vegetable samples poses individual non-cancerous risk after consumption. On the other hand, the measured ILCR values for Cd for both males and females ranged from 1.51E-04 to 6.45E-03 and 2.12E-04 to 9.03E-03, respectively, indicating cancer risk in all fruit and vegetable samples, either individually or cumulatively. Conclusion: The locally available fruits and vegetables of the Mymensingh divisional city area posed significant human health risks. However, regular monitoring of toxic metal contents is necessary to ensure the food safety of locally grown indigenous fruits and vegetables for the city dwellers
