Contamination profile of heavy metals in marine fish and shellfish
Rapid industrialization along with advanced agricultural activities led to the contamination in aquatic environment with heavy metals. Heavy metals ultimately pass into human body through having aquatic animals like fish, prawn and crab. In this study, accumulation of heavy metals (zinc, copper, iron, cadmium and lead) in various organs of four commonly consumed fish (Euthynnus affinis...
متن کاملExamination of Marine-Based Cultivation of Three Demosponges for Acquiring Bioactive Marine Natural Products
Marine sponges are an extremely rich and important source of natural products. Mariculture is one solution to the so-called "supply problem" that often hampers further studies and development of novel compounds from sponges. We report the extended culture (767 days) at sea in depths of 10 and 20 m of three sponge species: Negombata magnifica, Amphimedon chloros and Theonella swinhoei that produ...
متن کاملMarine larval fish production: a nutritional perspective
Introduction Many of the marine species that are currently being produced on a commercial basis are members of the group of fishes known as pelagic spawners. The reproductive strategy employed by these fishes involves the production of large numbers of small, buoyant eggs which, after being released into the water and fertilized, drift freely in surface currents with no further parental attenti...
متن کاملMarine fish egg hydration is aquaporin-mediated.
The positive buoyancy of marine fish eggs in sea water, allowed by hydration of the oocyte, is critical for their survival and dispersion in the ocean. We isolated an aquaporin, SaAQP1o, that belongs to a unique subfamily of aquaporin-1-like channels specifically evolved in teleosts and mainly expressed in the ovary. We further show that hormone-induced fish oocyte hydration is a highly control...
