Four species of microalgae were evaluated at different temperatures for their ability to remove ammonia from intensive marine fish/shrimp culture systems. Growth rates were highest on the first of three days of culturing for marine microalgae Nannochloropsis oculata, Isochrysis aff. galbana, Chaetoceros muelleri, and Tetraselmis chui. This rate was used to compare both the growth and the total ...

Biomass of the crustacean Artemia sp. has multiple uses. The biochemical composition and biomass production of Artemia grown from cysts produced by a native population from Real de Salinas were evaluated under laboratory conditions. Nauplii (instar I) were stocked at density of 10 nauplii/ml in 1.5 l tanks, fed with rice bran from day 2 to day 6, and with the microalgae Tetraselmis suecica from...

Microalgae have been widely reported as a promising source of biofuels, mainly based on their high areal productivity of biomass and lipids as triacylglycerides and the possibility for cultivation on non-arable land. The isolation and selection of suitable strains that are robust and display high growth and lipid accumulation rates is an important prerequisite for their successful cultivation a...

An experiment was conducted at the Asian Institute of Technology, Thailand, to investigate effects of fertilization rates and salinity levels on the growth of sex-reversed Thai red tilapia (Oreochromis sp.). The experiment was designed to test two fertilization rates (28 kg nitrogen and 7 kg phosphorus ha-1 wk-1, N:P = 4:1; and 14 kg N and 7 kg P ha-1 wk-1, N:P = 2:1) and three salinity levels ...

abstract this study was performed to compare the efficiency of 6 microalgae namely dunaliella tertiolecta, tetraselmis suecica, chlorella sp., (green algae), nannochloropsis oculata, spirolina sp.(blue-green algae) cheatocerus sp. (diatoma),  and isochrices sp. (haptophytae) on the growth, survival and reproduction efficacy in artemia urmiana in laboratory conditions. artemia cysts were harvest...

Powdered biomass of Nannochloropsis sp. and Tetraselmis were used as innovative ingredients in wheat tortillas at flour substitution levels 0.5–3.0%. Incorporation microalgae into the tortilla formulations led to increased protein fat content. The content phenolic carotenoids was also higher microalgae-enriched tortillas, especially for those enriched a level 3.0%. Not only but antioxidant capa...
