  • Life cycle and reproductive biology of major brackishwater species (e.g., Penaeus monodon, Liza parsia)
  • Nutritional requirements and feed formulation for larval and juvenile stages
  • Pond design, water exchange systems, and biofloc technology for finfish culture
• Block-4: Culture of Brackishwater Finfish and Shellfish-II
  • Disease diagnosis and management in brackishwater aquaculture (e.g., vibriosis, bacterial gill disease)
  • Stocking density, growth performance, and yield optimization techniques
  • Integration of aquaculture with mangrove ecosystems and sustainable practices
• Block-5: Mariculture
  • Offshore and nearshore mariculture systems (e.g., seaweed, abalone, giant clams)
  • Substrate-based and floating culture techniques for marine species
  • Regulatory frameworks and environmental impact assessments for mariculture

Subject-Specific FAQs

Q: How does salinity tolerance vary among brackishwater species? Salinity tolerance is species-specific; for instance, Penaeus indicus thrives in 10–35 ppt, while Liza tade prefers 5–20 ppt. Block-1 covers ecological zonation to address this variability.

Q: What are the critical water quality parameters for hatchery operations? Dissolved oxygen (>5 mg/L), ammonia (<0.2 mg/L), and temperature (26–30°C) are non-negotiable for larval rearing. Block-2 emphasizes these parameters in hatchery technology.
