Research Interests

  • Endocrine control of previtellogenic oocyte growth
  • Mechanisms controlling fecundity in fish
  • Evolution of vertebrate endocrine systems
  • Growth and reproduction of aquaculture species in NZ
  • Developmental Genetics

Current issues (potential research projects) in the NZ aquaculture industry include:
1. full artificial control of abalone reproduction
2. interaction between growth and reproduction in salmon
3. control of reproduction in eel, hapuka (groper) and giant kokopu
4. development of farming methods for new aquaculture species

  • Khalid Alqaisi (PhD) - evolution of steroidogenesis in starfish
  • Sean Divers (PhD) - induced spawning of eel
  • Yair Kohn (PhD) - oogenesis and egg quality in hapuka
  • Ali Falahati (PhD) - GDF-9 signaling in the eel ovary
