Nitrogen is one of the fundamental nutrients for algal growth, underpinning the microalgal biochemical composition. Therefore, this study compared the growth and proximate compositions of Tetraselmis chuii (Butcher, 1959), cultured in different nitrate (NaNO3) concentrations (25, 50, 100, 200 and 500 mg L-1). Thus, the cell density, optical density...

Microalgae are considered as natural producers of protein, lipid, carotenoids, and fatty acids that are important not only in human and animal nutrition but also in medicines. Selection of the best performing locally isolated strains should be carried out to assess the nutritional properties of them as they are well adapted to local environment and...

Data of this article describes growth, survival rate, water quality and hemato-biochemical indices of Nile Tilapia (Oreochromis niloticus) fry. To collect the data, the Nile Tilapia fry was reared in 30 L glass aquarium (18 fish/ tank) for 56-days under controlled environmental condition. Feed was prepared with 25 and 50% replacement of commercial...

In this study, an efficient, simple and eco-friendly biological method, immobilized Tetraselmis chuii beads (TetraBeads) were tested for its efficacy in maintaining water quality to improve the survival and growth of Penaeus monodon postlarvae. Results showed that the tanks, treated with Tetrabeads, were able to significantly (p < 0.05) sustain TAN...

Removal of nitrogenous and phosphorus compounds from aquaculture wastewater by green microalgae (Tetraselmis sp.) was investigated using a novel method of algal cell immobilization. Immobilized microalgae removed nitrogenous and phosphorous compounds efficiently from aquaculture wastewater. Results showed that Tetraselmis beads reduced significantl...

An experiment was conducted to evaluate the efficacy of different natural and artificial attractants in the diet of stripped snakeheads Channa striata. The experiment was conducted into two phases- Nursery and Grow-out. There were four treatments TC (Control), TG (Glycine), TA (Alanine) and TN (Nappi) for each phase with three replicates. In phase-...

Together with the fastest growing of aquaculture production, aquaculture industry also produces a large amount of wastewater that results in not only eutrophication of waterbody but also increases the aquaculture cost and threatening global sustainability. To overcome those barriers in the aquaculture industry, application of microalgae for wastewa...

Water quality in aquaculture has been considered to be an important factor that influences the growth and survival of fish in nursery to grow-out phase. A microalga, Chlorella vulgaris is utilized to filter chemical substances to maintain optimum water quality and growth of fish. The present study was conducted to know the efficiency of Chlorella v...

The spat settlement (spat density, recruitment and mortality) of edible oyster Crassostrea spp. were estimated for three sites (Nunia Chara–NC, Chowfoldandy–CD, and Sonadia Island–SI) located in Cox’s Bazar coast of Bangladesh from February 2019 to January 2020 deploying shellstring. Field observations were made every 15 days to understand the mont...

Data on growth, productivity, pigments and proximate composition of the four different indigenous marine microalgae (isolated from Cox's Bazar Coast) were collected to compare the growth performance, pigments and nutritional composition. Chlorella sp., Nannochloropsis sp., Tetraselmis sp. and Chaetoceros sp. are the four different marine microalgae...
