Key research

  • Simon de Lestang and Ian Potter - Determination of the roles played in the life cycle of the blue swimmer crab (Portunus pelagicus) by estuaries and marine embayments and the ways in which its biology in temperate and subtropical waters differs. Development of an approach to provide realistic estimates of the number of batches of eggs produced by the blue swimmer crab during its life cycle.
  • Kim Smith and Ian Potter- Biology of the champagne (spiny) crab Hypothalassia acerba on the lower west and south coasts of WA and the crystal (snow) crab Chaceon bicolor along the west coast. Development of methods that will enable the attainment of maturity of both species of crabs to be determined more accurately and thus facilitate better estimates of their size at first maturity.
  • Andrew Winzer and Howard Gill – Basic biological parameters of those species of sealouse which cause problems for commercial crayfishermen.
