“…This is attributed to the similar concentration of K + ions in the rearing water after fortification with potash. In support of our findings, Hurtado et al (2007) and Jana et al (2021) also documented that dietary lipid or protein or the ambient water salinity did not influence the Na + /K + ‐ATPase enzyme activities in the gill of shrimp.…”

“…From these eight shrimps carefully hepatopancreas (weight was recorded for calculation of HPSI) and intestine were dissected out and quickly homogenized (5% homogenate) in iced phosphate buffer solution (pH 7.4) for assay of digestive enzymes. Gills were homogenized (10% homogenate) in iced SEI buffer (pH 7.3) using an automated homogenizer (Miccra, D9, Remi India) under iced conditions (Jana et al, 2021; Saraswathy et al, 2021) for Na + /K + ‐ATPase assay. The tissue homogenates were then centrifuged at 7000 g for 15 min in a refrigerated centrifuge, and the aliquot supernatant was collected in sample vials.…”

A 60-day feeding trial was conducted to evaluate the optimum dietary lipid level in terms of growth performance, digestive enzymes and hemato-biochemical parameters of white-leg shrimp, Penaeus vannamei juveniles in inland ground saline water (IGSW) of 15 ppt salinity. The shrimps (avg. wt., 4.04 ± 0.03 g) were randomly distributed in six groups in triplicates (15 shrimps/tank, 290 L), viz., TCL40 (40 g/kg lipid) , TCL60 (60 g/kg lipid) , TCL80 (80 g/kg lipid), TCL100 (100 g/ kg lipid), TCL120 (120 g/kg lipid) and TCL140 (140 g/kg lipid). Six semi-purified hetero-lipidic (40-140 g lipid/kg), hetero-caloric (376-426 Kcal DE/100 g) and iso-nitrogenous (400 g crude protein/kg) diets were prepared and fed to respective groups four times daily. Weight gain (WG), specific growth rate (SGR), feed conversion ratio (FCR), and protein efficiency ratio (PER) showed higher quadratic relations (R 2 = 0.97, 0.98, 0.94 and 0.87, respectively) to dietary lipid levels (p < 0.05) with enhancing dietary lipid up to 60 g/kg. Whole body moisture and lipid contents exhibited a high linear (R 2 = 0.87 and 0.98) and quadratic (R 2 = 0.88 and 0.98) (p < 0.05) inverse relationship with enhancing dietary lipid levels up to 140 g/kg. Hemolymph hemocyanin, serum total protein and glucose level did not differ significantly (p > 0.05), but the TCL60 group showed significantly (p < 0.05) higher serum cholesterol and triglyceride levels. Serum osmolality, osmoregulatory capacity, and branchial Na + /K + -ATPase activity was similar (p > 0.05) among the groups. Hepatopancreatic lipase and amylase activity significantly (p < 0.05) increased, but trypsin activity did not vary significantly (p > 0.05) among the groups. Second-degree polynomial analysis with WG, SGR and FCR indicated that a 55.80-58.80 g lipid/kg diet is optimum for P. vannamei juveniles in IGSW of 15 ppt salinity.

“…If there is no benefit feeding higher concentrations of crude protein, this potentially results in improved economic efficiency. Several studies have demonstrated that shrimp experience better growth performance and lower FCR when fed higher protein diets (Xia et al, 2010;Shahkar et al, 2014;Jana et al, 2021); however, daily exchanges of water occurred in these studies. In contrast, other researchers reported that there is the possibility of reducing dietary crude protein concentration in shrimp feed without affecting growth performance when BFT is applied Panigrahi et al, 2019).…”

Formulated diets for animals is the primary source of nutrients in aquaponic systems that need to maintain beneficial bacteria as well as for plants. Dietary protein is one of the expensive macronutrients in fish diets, especially when fishmeal is used, and it is the source of nitrogen (N) for other biotic components. Biofloc has the potential to serve as the supplement diet for shrimp and reduce the need of expensive protein. However, it is not clear if low dietary protein will be adequate to support the three organisms (animals, plants, and bacteria) in an aquaponic system operated with biofloc technology. The aim of the present study was to investigate the effect of shrimp feed with different protein concentrations (30, 35, or 40%) on water quality and the growth performance of Pacific whiteleg shrimp (Litopenaeus vannamei) and three edible halophytic plants (Atriplex hortensis, Salsola komarovii, and Plantago coronopus) in biofloc-based marine aquaponics. The experiment was conducted for 12 weeks, the plants were harvested and seedlings transplanted every 4 weeks. Dietary protein content did not influence shrimp growth in the current study, indicating that feeds with lower protein concentrations can be used in biofloc-based marine aquaponic systems. During the early and mid-stages of cultivation, plants grew better when supplied diets with higher protein concentration, whereas no differences were observed for later harvests. Hence, for maximum production with mature systems or in the scenario of high concentration of nitrate, providing a higher protein concentration feed in the early stages of system start-up, and switching to a lower protein concentration feed in later stages of cultivation was recommended.

“…But, in compared to brackish and marine water, inland ground saline water (IGSW) is deficient of potassium ion with high calcium ions and variable concentrations of magnesium ions (Allan et al, 2001), which affect the physiological homeostasis and growth performance of fish (Aklakur, 2017). However, several countries have successfully cultured different euryhaline species in IGSW with or without fortification of potassium ions (Jana et al, 2006;Partridge and Lymbery, 2008;Jana et al, 2021a). Thus, genetically improved farmed tilapia (GIFT) could be the most suitable species for culturing in IGSW because of its high growth rate, disease resistance and tolerance to wide range of salinity and ionic variation.…”

Aim: The present study was conducted to optimize the dietary protein level in the diet of Genetically Improved Farmed Tilapia reared in inland ground saline water (IGSW) of 15 ppt ambient salinity. Methodology: Seven iso-caloric (400 kcal digestible energy, DE/100g), iso-lipidic (6%) and hetero-nitrogenous (20-50% crude protein, CP) purified diets were prepared for conducting the feeding trial. Following completely randomized design, the random distribution of 315 acclimatized fish (average body weight 4.01±0.01g) was made in seven groups namely, CP20, CP25, CP30, CP35, CP40, CP45 and CP50 in triplicate with the stocking density of 15 fish per replicate tank. Results: Weight gain percentage, specific growth rate, and expression of insulin like growth factor-I and insulin like growth factor-I receptor with higher quadratic relation (R2=0.94, 0.96, 0.90 and 0.93, respectively) to the dietary crude protein (CP) level significantly increased (p<0.05) up to 40% crude protein and beyond that the values significantly decreased. With higher quadratic (R2=0.83) relation, muscle RNA/DNA ratio was significantly highest in 40% crude protein fed group. With higher quadratic (R2=0.81 and 0.98, respectively) relations, significantly higher protease and lower amylase activities were found in 40, 45 and 50% crude protein fed groups. Interpretation: Second order polynomial regression analysis based on WG%, SGR and IGF-I gene expression revealed that the optimum dietary protein for GIFT juveniles could be 41.84, 40.66 and 42.22%, respectively. This data will be helpful for development of economic and environment-friendly feed for GIFT tilapia culture in inland ground saline water of medium salinity.
