Welcome to the FAMER Lab!

About us

Researchers in the FAMER Laboratory address objectives spanning biological oceanography, fisheries dynamics, and physiological ecology. Our work is principally concerned with marine and estuarine systems, and is led by Professor Iain Suthers.

 

 

Research Themes

Biological Oceanography 

We are interested in the role that oceanographic features, such as boundary currents, eddies, and upwelling events, have on the distribution and production of zooplankton and larval fish. We employ a variety of techniques including CTD profiles, mid-water trawls, plankton nets, in-situ and lab based Optical Plankton Counters, and gliders. With our collaborators we are working in waters from Queensland right down to Antarctica. To learn more about our work on biological oceanography, click here.

 

Plankton and Fish Size Spectra 

We are interested in how marine and estuarine size spectra control the transfer of energy from phytoplankton to fish at local, regional and global scales. We are currently developing an Australian database of estuarine size-spectra and a global database of zooplankton size-spectra from LED and Laser Optical Plankton Counters.

Fish Ecology 

The ecosystem demand by predatory fish is not understood, because it fails to include the considerable impact of juvenile fish, especially when they reside in an estuary. This project aims to determine the diet, and the size-and temperature-dependent growth and biogenetics of a species, from juvenile to adult; from estuary to the open sea. This study is also significant for fisheries management of economically important baitfish, by incorporating the size-based metabolism of a representative predator. The project is innovative by implanting acoustic transmitters, calibrated in a flume, to discover bioenergetic rates in the field. The outcomes include an ecosystem synthesis of related pelagic fish predators from catchment to coast. To learn more about our work on fish ecology, click here.

 

Fisheries Enhancement

Fisheries enhancement tools such as artificial reefs and fish stocking are becoming increasingly important for the management of coastal fisheries. Our research aims to provide a sound ecological basis for these tools, and to optimise their environmental benefits. We integrate individual, population and ecosystem processes, by incorporating stable isotope analysis and dietary studies, bioenergetics, and population and ecosystem modelling.
