Two green algae (Ulva rigida and Cladophora coelothrix), the mussel Mytilus galloprovincialis and the snail Rapana thomasiana from the Bulgarian Black Sea shore have been treated with diesel fuel (100mg l(-1)) in an aquarium with sea-water for three days. The lipids and their fatty acid changes have been examined. Significant changes have been observed mainly in the polar lipids and in the satu...

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...

This study examines the effect of pH changes on photosynthetic characteristics and the role of dissolved inorganic carbon (DIC) in determining the dominance of three species of macroalgae Chaetomorpha linum (O.F. Müller) Kützing, Gracilaria verrucosa (Hudson) Papenfuss and Ulva sp. in a Mediterranean coastal lagoon. Fluctuations of pH were measured in the lagoon in summer. Water column CO(2) an...

Axenic gametes of the marine green macroalga Ulva mutabilis Føyn (Ria Formosa, locus typicus) exhibit abnormal development into slow-growing callus-like colonies with aberrant cell walls. Under laboratory conditions, it was previously demonstrated that all defects in growth and thallus development can be completely abolished when axenic gametes are inoculated with a combination of two specific ...

Though the congeners Nutricola (=Transennella) confusa and Nutricola tantilla occupy an important ecological niche on mudflats, there is little published information concerning their population dynamics. We sought to determine what causational factors influence shifts in the relative distributions of these clams. Twelve cores were taken from Westside Park in Bodega Bay Harbor, California, in ar...

The optimised reduction of dissolved nutrient loads in aquaculture effluents through bioremediation requires selection of appropriate algal species and strains. The objective of the current study was to identify target species and strains from the macroalgal genus Ulva for bioremediation of land-based aquaculture facilities in Eastern Australia. We surveyed land-based aquaculture facilities and...
