...The net weight gained of broodstock was 103.65 g, 401.25 g, 484.85 g and 565.24 g in control, T₁, T₂, and T₃, respectively. Fish in T₃ yielded the highest weight, which was significantly higher than T₁,T₂ and control. Specific growth rates were not significant among treatments. Egg composition showed slight and statistically non-discernable variations. Same trend was observed when

Effects of Eyestalk Ablation on Feeding, Gonad Development, and Energy Conversion of Penaeus monodon Broodstock

...f Penaeus monodon broodstock. An experiment of 30 days was carried out on broodstock (average body length 28.4 ± 0.95 cm, average body weight 96.7±6.48 g) with (treatment) or without eyestalk ablation (control), cultivated under a water temperature of 27.0±1.5 °C, salinity of 30–32, pH of 8.0–8.3, and light intensity of 1000 lx. Results showed that food consumption and feeding inte...

Preliminary Assessment of Stock Enhancement in Swimming Crab (Portunus trituberculatus) Based on Molecular Markers

Shanshan Cai¹, Tianxiang Gao², Binlun Yan³, Aiyi Zhu¹ and Xiumei Zhang^1,2,*

...n this study, 524 female broodstock from 10 hatcheries and 547 recaptured crabs from 6 investigations were used to assess the proportion of released individuals and evaluate the effect of the program in Shandong Province in 2014. Parentage determination between broodstock and recaptured individuals was implemented by using mitochondrial control region fragments and three microsatellite markers. When using mtDNA loci, 242 ind...

Evaluation of Reproductive Capacity in Pond-Reared Penaeus monodon after Unilateral Eyestalk Ablation

...7.0-143.3g) were used as broodstocks in a continuous three-year breeding experiment. After unilateral eyestalk ablation, the relationships of egg and nauplii at the first spawning event and female bodyweight were evaluated. At each spawning, a female could produce 120000-1250000 eggs which hatched into 80,000-950,000 nauplii. The egg hatching rate at each spawning varied from 27.4% to 86.3% without particular patterns of correlation with female body weight. Th...

Feasibility of Ripening Penaeus monodon by using Pheretima tschiliensis as a Bait and its Verification by Vitellogenin Gene Expression

Song Jiang^1,2,3, Ming-ge Zhuang^1,2,3, Fa-lin Zhou^1,2, Qi-bin Yang¹, Jian-hua Huang¹, Li-shi Yang¹ and Shi-gui Jiang¹*

...ize: small;">Traditional broodstock diets, being susceptible to virus attacks or carrying the virus to parent shrimps, bring a huge bio-security risk to shrimp breeding. This study was carried out to determine the feasibility of Pheretima tschiliensis as a replacement of traditional bait to accelerate the maturity of parent shrimps of Penaeus monodon, which was verified by the dynamics of vitellogenin gene expression in hepatopancreas and ovary o...

Comparison of Morphometry, Physiological Status, and Protein Total in Twin and Single Ewes of Fat-Tail Sheep (Sapudi Indonesian Local Sheep) and Their Crossbred

...t;0.05) to differentiate broodstock in a single or twin brood in Sapudi sheep or their crosses, except for Suffas sheep. Total protein could show the difference between twin lambs having total protein > 6.36 g/dL and single lambs having total protein < 6.36 g/dL. The conclusion was that there was no relationship between physiological status, morphology, and total protein of the single and twin ewe in Sapudi sheep and their crosses, except for Suffas shee...
