Edibility of cultivated green seaweed Ulva intestinalis from Monkhali Beach, Cox's Bazar coast of Bangladesh: bio-toxicity and heavy metal contents.

Ulva intestinalis (UI) is widely available edible seaweed and has potential to be introduced as functional food items in Bangladesh. However, potential health hazards of this seaweed with biotoxicity assays and its relation to heavy metal contents were not evaluated previously. With these objectives, toxic effects of UI collected from floating raft culture in Monkhali Beach was evaluated using various organisms such as Chlorella vulgaris, Artemia salina, Daphnia magna, and Lactuca sativa.

Data on growth performance and nutritional composition of common carp () fry fed with sp.

A feeding trial spanning two months was conducted to evaluate the effects of sp on growth performance, water quality, survival, proximate composition and biochemical profile of common carp () where fishmeal was partially replaced using sp in the diet. Twenty uniform-sized common carp fries were distributed into triplicate groups and placed in 40-liter rectangular glass tanks. sp.

Quality evaluation of improved and traditionally dried Bombay duck () through biochemical, microbiological, and organoleptic analysis.

The study was conducted to compare the quality and shelf life of traditionally dried (collected from the local markets) Bombay duck () with improved dried products (produced using a newly developed fish dryer) to assess its suitability. The quality of these products was evaluated through organoleptic, water reconstitution, nutritional, chemical, and microbiological characteristics. The organoleptic quality of improved dried fish was excellent while those produced traditionally were with grayish and dark brown color, rancid odor, and soft and fragile texture with insect infestation.

Data on growth performance, proximate composition, and fatty acid content of edible oyster ( spp.), farmed on shellstring along Cox's Bazar Coast.

Data on growth performance, proximate composition and fatty acid content of Edible oysters ( spp.) were collected to evaluate the spatial variation in growth performance, proximate composition and fatty acid content of oyster. The oyster was farmed on shellstring for 120 days in the three sites: Nunia chara, Chowfoldandy and Sonadia Island.

Identifying hotspots for antibiotic resistance emergence and selection, and elucidating pathways to human exposure: Application of a systems-thinking approach to aquaculture systems.

Aquaculture systems are highly complex, dynamic and interconnected systems influenced by environmental, biological, cultural, socio-economic and human behavioural factors. Intensification of aquaculture production is likely to drive indiscriminate use of antibiotics to treat or prevent disease and increase productivity, often to compensate for management and husbandry deficiencies. Surveillance or monitoring of antibiotic usage (ABU) and antibiotic resistance (ABR) is often lacking or absent.

Anti-edema effects of brown seaweed (Undaria pinnatifida) extract on phorbol 12-myristate 13-acetate-induced mouse ear inflammation.

The brown seaweed Undaria pinnatifida (Harvey) Suringar is used in traditional medicine to treat fever, urination problems, lumps and swelling, and as a dietary supplement for post-childbirth women. We examined the anti-inflammatory activities of the seaweed. The methanol extract of the seaweed was active against mouse ear edema induced by phorbol myristate acetate (PMA), with an IC(50) of 10.

Effects of the brown seaweed Undaria pinnatifida on erythematous inflammation assessed using digital photo analysis.

The brown seaweed Undaria pinnatifida (Harvey) Suringar produced potent inhibition of erythematous inflammation assessed using digital photo analysis. The analysis technique was validated by laser speckle flowgraphy and blood vessel contraction. The methanol extract suppressed erythema by 50% when applied within 1 h before or 15 min after application of phorbol myristate acetate.

Isolation of two anti-inflammatory and one pro-inflammatory polyunsaturated fatty acids from the brown seaweed Undaria pinnatifida.

Two anti-inflammatory omega-3 polyunsaturated fatty acids (PUFAs) of stearidonic acid (SA) and eicosapentaenoic acid (EPA) and one pro-inflammatory omega-6 PUFA of arachidonic acid (AA) were isolated from the edible brown seaweed Undaria pinnatifida. SA was active against mouse ear inflammation induced by phorbol myristate acetate, with IC50 values of 160, 314, and 235 microg per ear for edema, erythema, and blood flow, respectively. EPA was also active against edema, erythema, and blood flow, with IC50 values of 230, 462, and 236 microg per ear, respectively.
