• To provide holistic knowledge on fish and shellfish pathogens and their control measures.
• To undertake surveillance of existing and emerging fish and shellfish diseases.
• To develop improved diagnostic techniques for the detection of existing and emerging fish and shellfish diseases.
• To develop prophylactic and therapeutic measures including herbal remedies with nutraceutical and immunostimulant formulations for the control of fish and shellfish diseases and study the pharmacodynamics and pharmacokinetics of select formulations.
Learners will have an in‐depth understanding of the need to incorporate social information in fisheries and wildlife management. Learners will be able to learn concepts in communications, group organization, and conflict resolution in fisheries and wildlife management. Students will also learn different types of pathogen and their treatments.
