“…The highest protein content (54 ± 1.05%) found at T5 treatment (150 g/L) and the lowest protein content (35 ±1.92%) found at the T1 treatment (50 g/L) whereas the standard nitrogen treatment, T3 (100 g/L) showed 47 ± 2.51% protein content. [35] found the similar findings for standard treatment in Nannochloropsis sp. cultured under the same physicochemical and environmental conditions.…”

Nitrogen is one of the key growth factors and structural constituent of the cellular molecules of Nannochloropsis sp. This study aimed to determine the influence of nitrogen stress in the form of potassium nitrate (KNO3 ) by altering the standard recommended nitrogen concentration to characterize the growth performance, proximate composition, and pigments content. The nitrogen concentration was arranged in following order for the culture of Nannochloropsis sp.: 50 g/L, 75 g/L, 100 g/L (standard), 125 g/L, and 150 g/L of KNO3 . All growth parameters, proximate composition, and pigment contents showed significant (p < 0.05) changes among the treatments. Cell density was increased by 2.48 folds, SGR was increased by 56.9%, and cells were doubled in number at a pace of 12.192 hours faster at the maximum nitrogen concentration (150g/L KNO3 ). The maximum protein content was 54 ± 1.05% at 150 g/L KNO3 while the highest lipid content was 36 ± 0.32% at 75 g/L KNO3 . The highest carbohydrate content was 24 ± 2.51% at 100 g/L KNO3 . The chlorophyll a content was increased to 0.632 ± 0.049 µg/L at 150 g/L KNO3 , while the highest carotenoids content was 3.301 ± 0.052 µg/ml at the 75g/L KNO3 . On the other hand, phycobiliprotein content was the highest 0.028 mg/g for the standard concentration of KNO3 . This study provides the commercial cultivation strategy for Nannochloropsis sp. by revealing the biomass productivity, biochemical and bioactive compounds status at different nitrogen-based culture conditions that will ensure their multipurpose use in aquaculture, pharmaceuticals, and nutraceuticals sectors.

“…The findings of the experiment was similar with the observations of Hossain et al (1998). The types and diversity of plankton varies depending on the season and physico-chemical parameters of the waterbody (Islam et al, 2022). Chlorophyceae showed an average cell density of 45.86×10 3 cells/l ± 1.15 in wishpond, 38.22×10 3 cells/l ± 0.83 in wishpond aquaponics and 36.37×10 3 cells/l ± 1.56 in traditional ponds during the experimental period.…”

“…The range 6.5-9.0 was reported as optimum for Tilapia culture and plankton growth (Jhingra. 1991;Islam et al, 2022). The values of pH ranged from 6.83 ± 0.57 to 7.60 ± 0.17 in wish pond, 6.93 ± 0.12 to 7.67 ± 0.76 in wishpond aquaponics, 6.73 ± 0.54 to 7.65 ± 0.18 in traditional ponds where the overall mean values were 7.15 ± 0.28 in wish pond, 7.29 ± 0.20 in wishpond aquaponics, and 7.10 ± 0.26 in traditional pond system.…”

“…On the other hand, bacillariophyceae-cyanophyceae, bacillariophyce-chlorophyceae and chlorophyceae cyanophyceae showed significant positive relationship in all the cases. It is important to know the algal community and its relationship among the groups as it is known as base the entire aquatic system (Islam et al, 2022). Table 4 described the correlations among the phytoplankton groups in case of wishpond aquaponics, wishpond and traditional pond system.…”

“…The knowledge of planktonic biomass available in an ecosystem is of fundamental importance for fish culture. The value of phytoplankton in a water body is the basic of food chain of fishes (Islam et al, 2022). The qualitative and quantitative abundance of plankton and its relation to environmental condition has become a prerequisite for fish production.…”

This study was designed to determine the interrelationship between physico-chemical parameters and plankton community in three different aquaculture systems (wishpond, wishpond aquaponics and traditional fish pond). The water quality parameters, dissolve oxygen (DO), temperature, pH, ammonia, alkalinity and transparency were monitored and found within the recommended range. Different phytoplankton of four (4) different groups were observed where Chlorophyceae group was the most dominant (8.03±0.19) × 103 cells/l in wishpond system and Euglenophyceae was the less dominant (45.86±1.15) × 103 cells/l in traditional pond system. In addition, Zooplankton of Rotifera was found the most dominant (17.81±0.09) × 103 cells/l with following Cladocera and Copepoda. A significance difference were observed in case of plankton groups among three different aquaculture systems. The interrelationship among the physico-chemical parameters, temperature showed strongest relationship with all the other physico-chemical parameters where transparency showed no relation with dissolve oxygen. In case of phytoplankton groups, all four groups showed more or less positive relationship in all three different aquaculture system. The findings of this study will assist small-scale producers in choosing and properly operating a simple aquaponics system. Asian Australas. J. Biosci. Biotechnol. 2022, 7 (1), 13-22
