Growth Performance, Morphological and Chemical Characteristics of Red Tilapia Fed Diets Supplemented with Dunaliella salina

Abstract

The aims of the present study were to investigate growth performances, morphological and chemical body characteristics, blood profiles of Red Tilapia upon dietary Dunaliella salina (D. salina) supplementation. Control and D. salina diets were formulated isonitrogenous and isoenergetic (339.99±0.02 g/kg & 4.5 ± 0.0028 Kcal/g, respectively) and fed during the study. The formulated diets were control diet and D. salina diets supplemented with 33.0, 66.0 and 100% and fed thrice a day to fish (14.37±0.15 g g) for fourteen weeks in 16 tanks containing 30 fish in each. Body weight gain, feed efficiency and morphological and chemical body characteristics of treated D. salina fish were determined in addition to changes in flesh color and blood profiles (red blood cells, hematocrit, glucose and total protein) compared to control one. The results indicated that replacement of fish meal with 33.0% D. salina resulted in comparable results with control diet concerning body weight gain, feed efficiency, morphological and chemical body composition and blood profiles. Diet containing 33% of D. salina had no significant effect in protein productive value when compared to control diet versus 66 and 100% D. salina diets, which decreased the parameter. Productive value of energy was not differed (P > 0.05) between control and D. salina treated groups. On the other hand, the high levels of D. salina (66.0 & 100%) were mostly decreased all the recorded parameters compared to control and 33.0% D. salina diets except body fat content and flesh color, which were significantly (P < 0.05) improved. In conclusion, replacement of fish meal with 33.0% D. salina could be promising of Red Tilapia growth performances, feed efficiency and chemical characteristics.

Dietary supplementation with a mixture of Dunaliella salina and Spirulina enhances broiler performance by improving growth, immunity, digestive enzymes and gut microbiota

“… Abdelwahab et al (2020) indicated that the substitution of fish meal with a low level of D. salina (33.0%) produced similar findings as the control diet with respect to BWG and FCR. Fernandes et al (2020) reported that D. salina has favorable bioactive concentrations of constituents, which may be used in poultry feed.…”

“…Recent interest has grown in the use of D. salina as a novel feed supplement for nutritional purposes ( Mohammed, 2018 ). D. salina provides many health benefits to animals due to its high β -carotene content, which can safeguard against central nervous system O 2 toxicity ( Bitterman et al, 1994 ) and gut inflammation through antioxidant and immunomodulatory properties ( Abdelwahab et al, 2020 ). A broiler chick's diet supplemented with D. salina and Spirulina is predicted to extend favorable impacts on birds.…”

Effects of Replacement Fishmeal with Biofloc on Feed Utilization and Growth Performance, Morphological and Chemical Characteristics of Red Tilapia

“…The color of fish flesh minces of control and biofloc groups were determined using Hunter (Almadani, 2017;Abdelwahab et al, 2020). Mince color examination of L, a , and b values are used to determine color of fish flesh minces of control and biofloc groups.…”

“…The demand for these products has increased steadily, along with the increase in the demand for feed. It is known that protein is one of the main components of feed for aquatic organisms such as fish and crustaceans (Abdelwahab et al, 2020). Fish feed is considered more than half of the costs of the fish farming project.…”

Effects of Dietary Microalgae Inclusion on Feed Utilization, Morphological and Chemical Characteristics and Body Health in Fish: Advantages and Disadvantages

“…Dietary microalgae inclusion in small or large amounts to mammalian and fish species are considered one of the most important feed supplements for improving nutritional values and productive performances throughout the world (Abdelwahab et al, 2020;2023). They gained prominence and limelight continuous interest because of their crucial roles for mammalian and fish species (Mohammed 2018(Mohammed , 2022Ali et al, 2021;Al-Mafurji et al, 2022;Molina-Roque et al, 2022).…”
