The Pacific oyster (Crassostrea gigas), originally from East Asia, has been the main species of oyster farmed in Europe since the early 20 century. Populations were heavily hit by disease in the 1960s and 1970s and thousands of tons of Pacific oysters from Canada and Japan were subsequently imported to replenish French farm stocks. However, a number of other species inadvertently arrived with t...

Impact of three different types of seaweed diets on growth, feed utilization and nutrient digestibility of L. rohita was studied for 120 days. The seaweed diet fed fishes, especially Ulva based diet showed comparatively higher growth and weight increment. Good food conversion ratio, food assimilation efficiency, protein efficiency ratio and better nutrient digestibility were recorded for seawee...

Test materials used in form and lactobacillus. container implementation this is 6 bottles 1000 ml size, before are first washed clean. Then each bottle filled with extracts Sa...

This paper highlights the potential of Sargassum algae, recovered from raw beach seaweed wastes, as a valid source valuable sodium alginate. Alginate is biodegradable, highly attractive polysaccharide widely used in food, pharmaceuticals, and biomedicine applications. The aim this work to employ new eco-sustainable cost-effective extractive method obtain alginate material pollutant organic seaw...

Located in Teluk Bayur bay the port is of five biggest and busiest ports Indonesia. High sea transportation activities anthropogenic may lead to heavy metal pollution. The purpose this study was determine concentration Pb Cu metals, seagrass (Sargassum sp.) analyze feasibility consuming Sargassum sp. method used a survey method, by analyzing at Laboratory Pekerjaan Umum Riau Province. water qua...

In theory, plants could induce resistance to herbivores after being directly grazed or after sensing cues from the grazing of neighboring plants (i.e., the ‘‘talking trees’’ effect). Despite an extensive literature on induced defenses in plants, the relative importance of direct attack versus cues from neighbors in mediating induction is not well understood; this is especially true for seaweeds...

Methods The HIV inhibitory activity of aqueous and methanolic extracts of S. swartzii was determined on laboratory adapted strains of HIV-1 clades C and A by indirectly measuring reduction in HIV-1 gag p24 antigen levels and inhibition of HIV-1 RT activity in supernatants of virus infected donor peripheral blood mononuclear cell (PBMC) cultures grown in varying concentrations of the extracts. P...

six species of sargassum c. agardh (sargassaceae) with compressed primary branches, including: s. binderi sonder, s. aquifolium (turner)c. agardh, s. oligocystum montagne, s. swartzii (turner)c. agardh, s. crassifolium j. agardh and s. cristaefolium c. a. agardh, were identified in the persian gulf and oman sea coasts, among which s. binderi is reported as newly recorded species in iran for the...
