Dr. Shivendra Kumar

Long-term objectives of his recruitment0_Intro1_0.jpg

  • to generate and participate in the research project of Fish Nutrition and Physiology
  • application of novel molecular tools and methods in fish nutrition and physiology (Nutrigenomics):develop molecular biomarker in relation to essential nutrient deficiency in the diet of carp
  • emphasise the research on the formulation of low-cost fish feed and on the interaction of environmental changes with the nutrient requirement of fish
  • to develop artificial carp larvae feed from the first day after hatching
Dr. Shivendra Kumar recruited on the position of Senior Researcher in the Department of Fish Nutrition and Fish Physiology at NAIK – HAKI, Hungary in the frame of AQUAREDPOT FP7 project. He is involved in the research contributing for profound insight on metabolic utilization of nutrient and nutrient-gene interaction in fish. His research is based on gaining basic information regarding physiological and molecular aspect of nutrition for scientific sound improvement in fish feed. Evaluation of the utilization potential of alternative feedstuffs for partial or total replacement of fish meal and fish oil in the diets to reduce pressure on fisheries and decrease fish feeds dependence on this limited commodity is also a main concern. Understanding the interaction of multiple stressors in climate change scenario and its mitigation strategy through nutritional intervention is another priority research area.

 

Prior to the mentioned recruitment, Dr. Kumar was employed as Scientist (Fisheries) at Rajendra Agricultural University, Pusa, Bihar, India and involved in participatory research, research based extension and teaching of graduate students. He has started his academic career with 4 years Bachelor studies on Fisheries Science in India (Rajendra Agricultural University, Pusa, Bihar, India). After successful completion of BSc, he pursued MSc (2002-2004) in ‘Fish Nutrition and Biochemistry’ from Central Institute of Fisheries Education (CIFE), Mumbai, India. His MSc dissertation work was on “Effect of gelatinization and exogenous amylase on growth and nutrient utilization in the diet of Labeo rohita fingerling” and won ‘Dr. N. R. Menon Best Post Graduate Thesis Award’ hosted by “PFGF, India”. After that, he started PhD in the same lab (CIFE, India) on ‘Metabolism and Immuno Modulation of Thermally Exposed Labeo rohita under Different Dietary Regime’ and awarded Ph.D in the year 2009. His Ph.D research was mainly focused on physiology of temperature regulation, stress physiology and Heat shock protein with the problem of poor initial growth of carp. Society of Biological Science and Rural Development (National Academy of Biological Sciences and Rural development) New Jhusi, Allahabad, Uttar Pradesh, India awarded him with “Young Scientist Award (2013)” for his contribution in fisheries and aquaculture research.

 

Dr. Shivendra Kumar done the following main research activities within HAKI since 2014:

1. In the frame of the project, ‘Evaluation for potential of using processed animal protein (PAP) ingredients to replace fish meal in practical diets for European Catfish (Silurus glanis)’ he is aiming at to develop a cost-effective pond based practical feed for Silurus glanis and test the Processed Animal Protein (PAP) as protein supplement in place of fish meal for sustainable aquaculture feed and food production.

2. He is also taking part in a Nutritional Programming in Common Carp juvenile focusing on a crossover experiment with fish based (FF) and plant based (PP) feed. This experiment was aimed to investigate that “Does nutritional history of Common carp during early feeding stage impact the change in diet during juvenile stage?”

3. The third research is about weaning strategy with dry starter diet supplemented with vitamin (C & E). This experiment was designed to develop strategy for weaning common carp larvae with dry microencapsulated diet supplemented with vitamin C and E and replace live food (Artemia).
