How and why did two mud crabs travel 200 kilometres?

Fisheries, aquaculture and oceanography enthusiasts are invited to a free event on Thursday 15 November to hear a range of presentations from local and interstate scientists.

Attendees will learn how oceanographic and climatic events can have a significant impact on the productivity of inshore fisheries and hear about recent advances in aquaculture production in the north.

The event is being coordinated by Dr Mark Grubert, Senior Fisheries Scientist with the Department of Primary Industry and Resources.

Mark will use a combination of oceanographic particle tracking modelling, sea surface temperature data, and a 1980's cult film reference to describe possible mechanisms and motivations behind Bill and Ted’s Excellent Crustacean Migration – a journey of around 200 km during a marine heatwave event in 2016.

The mini-symposium will consist of presentations from:

  • Dr Madeleine Cahill, CSIRO Marine Research – “IMOS OceanCurrent data portal”
  • Dr Julie Robins, Queensland Department of Primary Industry and Fisheries – “Barramundi research and management in Queensland”
  • Mr Paul Armstrong, Northern Territory Department of Primary Industry and Resources – “Tropical Rock Oyster Aquaculture”
  • Ms Amy Kirke, Charles Darwin University – “The biology and ecology of four sharks caught in Northern Territory fisheries”
  • Ms Zoe Collishaw, Monsoon Aquatics – “Culture and care of local aquarium species”.
  • Dr Mark Grubert, Northern Territory Department of Primary Industry and Resources – “Bill and Ted’s Excellent Crustacean Migration”.

The event will be held at the Museum and Art Gallery of the Northern Territory, 19 Conacher Street, from 10am to noon on Thursday 15 November.

This free event is open to the public and bookings are not required.
