چکیده
Nile tilapia is a freshwater fish that widely cultivated in Indonesia. During its development, aquaculture has constraints such as low growth rates. Therefore, it necessary to add feed additive the form of charcoal. Charcoal an adsorbent high absorption so addition charcoal can increase nutrients tilapia. A 45-days trial was conducted determine percentage triggerfish bone (Abalistes stellaris) supplement affect performance and intestines The research design non-factorial Completely Randomized Design (CRD) with 4 treatments 2 replications including: treatment (control), B (addition 1%charcoal), C 2% charcoal) D 3% charcoal). total 240 fingerlings (5-7 cm) were used placed 8 aquariums then filled 72 liters water. Providing adlibitum (unlimited) frequency times day. ANOVA test showed (A. not significantly different (P 0.05) weight growth, absolute length daily but conversion ratio efficiency utilization. Based on result, concluded best which gave lengthiest villi increasing intestinal 71.11 µm from initial 162.22 µm. easel at 233.33 μm, highest value (1.12 %, 89.6%).Keywords:CharcoalFish boneIntestinal histologyStarry

This study was conducted to evaluate the effect of different levels of dietary supplementation of Saccharomyces cerevisiae on growth performance, feed utilization and body biochemical composition of Oreochromis niloticus fingerlings. Four diets containing supplementation at levels of 0, 0.5, 1 and 2 g kg−1 were fed to fingerlings of Nile tilapia (5.01±0.21 g) in four replicate tanks twice ...

This study aims to get a comprehensive evaluation of the growth promoting effects and the hypoxic stress relief potentiality of Moringa oleifera aqueous extracts. Oreochromis niloticus fingerlings were arbitrarily allocated into five duplicated fish groups (30 fish tank-1). The fish groups were labeled according to the M. oleifera aqueous extract dietary inclusion level (G1:G5). MOAE had fundam...
متن کاملDistribution of intestinal enzyme activities along the intestinal tract of cultured Nile tilapia, Oreochromis niloticus L
Regional distribution of intestinal enzymes in Nile tilapia was investigated using enzyme histochemistry. Samples from adult fish were obtained from the five major intestinal segments. Activities of maltase, leucine aminopeptidase, dipeptidyl aminopeptidase IV, lipase, non-specific esterases, and alkaline phosphatase were examined in each segment. All enzymes were present at specific sites alon...
