Live feed is the basic food source and nutrient security for successful seed production of any commercially important aquaculture species fishes, mollusks crustaceans. Both plant animal originated aquatic microscopic organisms are generally termed as live food. They items in early stages (larval stage) life cycle due to small sizes, easy digestibility enriched nutrients. The Nannochloropsis sp....

In the pursuit of sustainable sources for food, energy, and health products, microalgae have gained attention. present study, lagoonal system Nestos River delta was selected as a sampling point in order to search opportunistic robust species. Two new strains Tetraselmis are described with regards their taxonomic features (as observed using light transmission electron microscopy molecular phylog...

With the depletion of global fish stocks, caused by high demand and effective fishing techniques, alternative sources for long chain omega-3 fatty acids are required for human nutrition and aquaculture feeds. Recent research has focused on land-based cultivation of microalgae, the primary producers of omega-3 fatty acids in the marine food web. The effect of salinity on fatty acids and related ...

A Tetraselmis sp. was selected for its antioxidant activity owing to high lipid peroxidation inhibition capacity. With the aim monitor culture conditions improve activity, effects of CO2-induced acidification on growth, elemental composition, photosynthetic parameters and were determined. Two pH values tested (6.5 8.5) in batch continuous cultures photobioreactors. Acidification enhanced cell g...

The increasing sea surface temperature could be approved CO2 levels on the coast. It has been assumed primary productivity in intertidal zone was to absorb from water column for photosynthesis. In addition, substrate floor a potential source of decomposers. Phytoplankton and seagrasses are zone. Both them have chlorophyll, they maintain as carbon move photosynthetic systems develop metabolism b...

The Chlorodendrophyceae is a small class of green algae belonging to the core Chlorophyta, an assemblage that also comprises the Pedinophyceae, Trebouxiophyceae, Ulvophyceae and Chlorophyceae. Here we describe for the first time the chloroplast genomes of chlorodendrophycean algae (Scherffelia dubia, 137,161 bp; Tetraselmis sp. CCMP 881, 100,264 bp). Characterized by a very small single-copy (S...

During the Mesozoic Era, dinoflagellates, coccolithophorids and diatoms became prominent primary producers in the oceans, succeeding an earlier biota in which green algae and cyanobacteria had been proportionally more abundant. This transition occurred during an interval marked by increased sulfate concentration in seawater. To test whether increasing sulfate availability facilitated the evolut...
