I am a 2nd year PhD student at University of Stirling within sustainable aquaculture group.

My research topic is related to high welfare practices in shrimp hatcheries. In general shrimp are induced to maturation and spawning by eyestalk ablation (removal or constriction of one/two eyestalk), however it is considered to be a cruel method as it may create trauma, stress associated to physiological imbalance condition, reduce immunological defense and even shorten the shrimp reproductive exhaustion. Growing consumer awareness about animal welfare and ethics in food production has made eyestalk ablation a cause of concern for shrimp farmers, retailers and seafood certifiers. Thus I am working on alternatives to replace eyestalk ablation in shrimp hatcheries, specifically for Pacific white Shrimp (L. vannamei), and their impact on reproduction and offspring quality of the shrimp. 

Previously I worked with inland marine shrimp culture and biofloc technology. I evaluated the effect of potassium and magnesium ions on performance of Pacific white shirmp (Litopenaeus vannamei) reared in low salinity water and biofloc system. 

I do have further experience on tilapia culture, water quality management, research techniques and teaching.
