Abstract

The Gracilaria genus is a potential source of natural and environmentally-friendly alternatives in improving the survival and growth of shrimp. This study aims to identification immunostimulant molecules extract G. verrucosa and evaluate the utilization of G verrucosa extract as an immunostimulant in improving survival and growth of L. vannamei. Seaweed extraction used ethyl acetate then formulated in the diets. The immunostimulant molecule in the G. verrucosa was analysis. The shrimp were fed a test diet containing extract G. verrucosa at a dose of 2 g kg-1 or extract G. verrucosa-free control diets for 42 days. Shrimps were fed diets containing extract with a specific duration. The observation on the survival and growth of L. vannamei was performed after maintenance at the Laboratory for six weeks. Following, diets containing extract was tested in the field (pond shrimp farm) at the same dose of extract for 58 days. Shrimp was feed diets containing extract once a week, once in the early culture, and diet control, then the survival and growth shrimp were analysis. Concentrations of sulfates and carbohydrates in G. verrucosa ethyl acetate-extract were 24.21% and 13.41%, and crude protein 3.64%. GC-MS pyrolysis results show that G. verrucosa polysaccharide is similar to immunostimulant molecules. The survival shrimp gave diets containing G. verrucosa extract formulation was higher than that of shrimps fed controls diet. The Shrimp fed diets extracts have higher growth than shrimp given control dietsKeywords: Gracilaria, extract, polysaccharides, immunostimulant

Abstract

The aim of the present study was to investigate the growth performance of Nile tilapia immersed in 17α-methyltestosterone (MT) and recombinant giant grouper growth hormone (rElGH), and fed a rElGH-enriched diet. A total of 200 tilapia larvae aged 10 days and 14 days post hatching was immersed in 1 liter of 30 g/L saline water for 3 minutes, then in freshwater containing either MT, MT+rElGH, or rElGH for 4 hours. The MT dose was 2.0 mg/L and rElGH was 2.5 mg/L. As control was treatment without MT and rElGH. Fish were maintained in 250-L aquariums for 6 weeks and then moved to net cages for 8 weeks of rearing. The rElGH-enriched diet was fed to the 6-week-old fish for a month, and then fed a non-enriched diet. Each treatment was triplicates. The result showed that the daily growth rate (DGR), biomass gain (BM), survival (SR) and feed (artemia nauplii) consumption during maintenance in the aquariums in the rElGH and MT+rElGH treatments were higher (P<0.05) than in the control. The higher DGR and BM at net cage rearing and lower feed conversion ratio (P<0.05) were also found in MT and MT+rElGH treatments. None of the treatments showed any difference in survival (P>0.05). Profits estimation in the MT and MT+rElGH treatments were 63.38% and 57.91% higher than the control. The present study concluded that higher Nile tilapia farming performance could be obtanied by MT immersion in the larval phase and feeding juvenile on the rElGH-enriched diet.

Abstract

Synodontis eupterus male represents only 5-10 % of farmer total synodontis production, which limits male availability for reproduction purpose. A method widely used in overcoming the low male production was masculinization through synthetic hormones, which was restricted due to its adverse impact on the environment. Natural ingredients from plant were demonstrated in various studies to substitute the 17α-methyltestosteron hormone on masculinization. This research aimed at evaluating the effects of Javanese long pepper extract (JLP) through immersion on synodontis fish larvae. The research was conducted using factorial design with two faktor (4x2) consisted of eight treatments: 17α-methyltestosteron 2 mg L-1 (MT) immersion for 5 and 10 hours, JLP dose 0.125 mg L-1 (P1) immersion for 5 and 10 hours and dose 0.25 mg L-1 (P2) immersion for 5 and 10 hours compared to the control treatment without immersion (P0). A hundred of synodontis larvae of 10 days old after hatching each replication were used in the immersion treatments. The results showed that JLP treatments produced 25-40 % of male synodontis age four months, 1-2 % females and above 60 % intersex. While at age five months, the percentage of intersex fish decreased to 20-40 %, the female fish increased to  60-62 %, and male fish ranged 20-35 % in JLP compared to the control P0 (15 %). The dose of JLP 0.25 mg L-1 increased mortality of about 14-54 %.

Abstract

An experiment was designed to study the effects of curcumin and thyroxine hormone supplementation in the diet to improve the reproductive performance of catfish broodstock by improving egg quality that eventually increases the production of seedlings. Catfish used in this experiment were supplemented with curcumin and thyroxine hormone through their feeds for 12 weeks. The results showed that there was no significant difference (p > 0.05) in the hepatosomatic index (HSI), gonadosomatic index (GSI), percentage of gonad maturity, total cholesterol concentration in the spawned eggs, high density lipoprotein (HDL) concentration in the spawned eggs, fertilization rate of spawned eggs, and hatching rate of fertilized eggs.  However, there were significant differences (p < 0.05) in the concentration of vitellogenin in the spawned eggs, egg diameter of the spawned eggs, and the triglycerides contents of spawned eggs. It was concluded that curcumin and thyroxine supplementations of African catfish increased vitellogenin concentrations and diameters of spawned eggs that have great potential to improve the reproductive performance.
