“…Light source (white fluorescent bulbs) and aeration were constantly provided during the culture period. Once the culture reached their stationary phase, T. chuii cells were harvested by centrifugation at 4000 rpm, for 30 min, while S. platensis biomass was collected by filtration using a plankton net (20‐µm mesh size), as described by Hasanein et al (2018). Produced algae pastes were formed as pressed thin sheets, oven‐dried at 45°C (for 24 hrs), grinded into powder and stored at 4°C until used in feed formulation.…”

The current study evaluated the use of two supplemental microalgae, Spirulina platensis and Tetraselmis chuii, and decapsulated artemia cysts as novel diets for post‐weaned common sole (Solea solea) larvae. Four isonitrogenous (55% CP), isoenergetic (22 MJ kg−1) post‐weaning diets were prepared; a control, algae‐free diet and two control diets supplemented with 50 g kg−1 diet of dried S. platensis (SD) or T. chuii (TD). The fourth diet consisted only of decapsulated artemia cyst powder (AD), enriched with 50 g kg−1 diet of docosahexaenoic acid (DHA). A fifth, commercial marine larval diet was used as a reference diet, for comparison. The diets were fed to S. solea larvae (10 mg fish−1, 42 days post‐hatch), at a daily rate of 20% of their live weight, five times a day, for 28 days. The results indicated that AD diet induced the highest growth rates, followed by TD‐ and SD‐supplemented diets, respectively, whereas the control and commercial diets displayed the lowest performance. SD‐ and AD‐fed groups had the highest body protein contents, while body lipids were not significantly affected by dietary treatment, except the AD group which exhibited significantly higher lipid level. The results also indicated that AD‐ and algae‐supplemented diets produced significantly higher survival rate and body n‐3 HUFA, EPA, DHA and n‐3/n‐6 ratio than the control and commercial diets. This study demonstrated that enriched decapsulated artemia cyst powder could be an excellent post‐weaning diet for common sole (S. solea) post‐larvae. The present results also suggest that inert microdiets enriched with 50 g kg−1 diet of Spirulina platensis or Tetraselmis chuii can serve as excellent diets for these post‐larvae.

“…Two out of four microalgae species found in the water samples from Rawa Besar Small Lake have been used as ingredients in aquaculture feedant. Arthrospira is the second most abundant species, and has been used to make feedants for white shrimp (Litopenaeus vannamei) (Macias-Sancho et al, 2014), Nile tilapia (Oreochromis niloticus) (Abdel-Tawwab et al, 2009), and sea bass (Dicentrarchus labrax) (Hasanein et al, 2018). Kirchneriella has been successfully tested on mollusks such as pearl mussels (Hyriopsis myersiana) (Kovitvadhi et al, 2008), but it is the least abundant species of microalgae in Rawa Besar Small Lake.…”

One of Rawa Besar Small Lake’s roles for the surrounding community is as a fishing spot. Locals would often go fishing at the edges of the small lake. The ability of a lake to provide fishes to catch is partly due to the availability of food in the ecosystem, most importantly the microalgae community as the main producer in the freshwater food web. This concept is used in aquaculture as a way to obtain a more sustainable ingredient for feedant. Microalgae are used for aquaculture feedant due to its nutritional value. However, it is important to assess the safety and suitability of microalgae used for feedant due to the difference in toxicity and nutritional value of various microalgae species. Observation of the water samples taken from Rawa Besar Small Lake shown that potential microalgae species like Kirchneriella and Arthrospira lives in Rawa Besar Small Lake. However, toxic microalgae species like Planktothrix has been found in said water sample as well. Isolation of potential species is necessary in order to produce a healthy feedant for aquaculture out of Rawa Besar Small Lake’s microalgae community

“…Commercial medium production depends on replacement of high cost medium components by another considerably low cost components as verified by (Abou El-Kheir et al, 2016) who succeeded in modification of Zarouk medium for large scale Spirulina production by using urea and phosphoric acid as commercial fertilizers. The same technique was used in Chlorella large scale production (Hasanein et al, 2018) . In this field, ongoing studies and techniques are recommended for developing commercial low costs medium for outdoor large scale algal production.…”

Thalassiosira are commonly used algae in mass production (Muller-Feuga, 2000). Certain species from different phytoplankton classes could overcome stress in natural environment, as they can exceed other microalgae classes, sometimes they vigorously grow and forming bloom generating secondary metabolites in the surrounding aquatic environment (Taheri et al., 2017). Influence of pH factor on the metabolic activity, biochemical constituents and ultrastructure of various algae was tested by (Sharma et al., 2012, Safafar et al., 2016. Also light intensity, temperature and minerals affect growth of cyanobacteria detected by (Katoli et al., 2015). There is a relation between phytoplankton uptake of inorganic carbon during photosynthesis process and increase pH of the surrounding environment (Hansen, 2002). However, in the algal culture medium pH is considered one of the most important factors influence optimal algal growth, it controls algal metabolism and affects its bioactive products biosynthesis (Liu and Lee, 2000). Chlorella spp. and Scenedesmus spp. are green phytoplankton commonly incorporated in food industries because of its high protein and lipid content, (Barka and Blecker, 2016). Nannochloropsis spp. of phytoplankton belongs to Eustigmatophyceae. Although its first record was in marine water (Vareltzis and Undeland, 2012) it commonly recorded in both fresh and marine environment. This species gained its importance from its high biochemical constituents and its possible mass production. A laboratory study about Chlorella spp. use as safe protein source for consumption and dietary supplementation and as natural food for some zooplankton species was tested by (Hegab et al., 2019) and concluded that Chlorella vulgaris is used as food source for Brachionus plicatilis and Heterocypris salina. Zooplankton species grazing and ingestion rates were mainly depending on Chlorella densities. Chlorella vulgaris, Scenedesmus quadricauda and Nannochloropsis oculata are known to be used in biodiesel production (Metsoviti et al., 2019) and as feed for fish (Pulz and Gross, 2004). Optimization of the conditions of algal cultivation may lead to production of algal biomass in adequate microalgae quantity (Vasileva et al., 2015).The major scope is using of algae as feed to higher planktons and other organisms in the food web. Microalgae proteins are one of the most important sources of protein to fill the gap in usual protein sources (Barka and Blecker, 2016). Micro algal protein content of Spirulina paltensis constitutes (50-65%) compared to fish protein (24%), (Moorhead et al., 2011). Chlorella vulgaris protein constitutes (43-58% of its dry weight) differs by culture conditions (Safi et al., 2014). Algal usage in different industries in cosmetics, food products enlarge the need for mass production of algae, so there is a growing interest for focus studies on the algal optimum condition needed for optimum growth. So, this study investigate the growth response and total biochemical content of three species of phytoplankton cultu...
