Abstract
- This study evaluates the impact of dietary supplementation of the blue-green alga Arthrospira platensis NIOF17/003 nanoparticles (AN) on the growth performance, whole-body biochemical compositions, blood biochemistry, steroid hormonal, and fry production efficiency of Nile tilapia (Oreochromis niloticus) broodstock, during the spawning season. After a 21-day preparation period to equip the females and ensure that their ovaries were filled with eggs, mating between the mature females and males took place in a 3:1 ratio during a 14-day spawning cycle. A total of 384 tilapia broodstock 288 females and 96 males with an initial body weight of 450.53±0.75, were divided into four groups; AN<subscript>0</subscript>: a basal diet as a control group with no supplementation of Arthrospira platensis, and the other three groups (AN<subscript>2</subscript>, AN<subscript>4</subscript>, and AN<subscript>6</subscript>) were diets supplemented with nanoparticles of A. platensis at levels of 2, 4, and 6 g kg<superscript>─1</superscript> diet, respectively. The results found that fish-fed group AN<subscript>6</subscript> showed the highest significant differences in weight gain (WG), final weight (FW), feed conversion ratio (FCR), protein efficiency ratio (PER), and feed efficiency ratio (FER). Females fed the AN<subscript>6</subscript> diet showed the highest significant fat content. Compared to the AN<subscript>0</subscript> group, fish fed on the supplemented diets showed significant improvement (p < 0.05) in triglyceride, glucose, and aspartate aminotransferase (AST). A gradual increase in AN inclusion level resulted in a gradual increase in the concentrations of luteinizing hormone (LH), and follicle-stimulating hormone (FSH), testosterone, progesterone, and prolactin. The rates (%) of increase in fry production for females fed supplemented diets were 10.5, 18.6, and 32.2% for AN<subscript>2</subscript>, AN<subscript>4</subscript>, and AN<subscript>6</subscript>, respectively, compared to the control group. This work concluded that the inclusion levels of 6 g kg<superscript>─1</superscript> of A. platensis nanoparticles in the diet of Nile tilapia broodstock significantly improved the growth performances, steroid hormone concentrations, and increased the fry production efficiency by 32.2%, respectively. These findings revealed that A. platensis nanoparticles resulted in a significantly enhanced female' reproductive productivity of Nile tilapia broodstock. [ABSTRACT FROM AUTHOR]
