Phase 1 - Fish Passage Assessment

A fish barrier is any obstacle that prevents fish movement either upstream or downstream and includes dams, weirs, floodgates, roads, bridges, causeways, culverts, bunds, tide gates and drop structures.These structures can form a physical, hydraulic or behavioural barrier to fish movement.  Waterways completely blocked by weeds,  where the dissolved oxygen of the water is reduced to zero can also form a barrier.  

Most fish need to move between habitat areas. Restrictions in fish movement can have significant impacts including affects on spawning migration, dispersal, gene flow and feeding. The congregation of fish in the vicinity of barriers can result in disease and predation. For those species which rely on upstream and downstream migration, fish barriers can result in local extinction.

Burdekin Dry Tropics Natural Resource Management and Alluvium Consulting are working together to undertake fish passage and assessment throughout the Burdekin Dry Tropics region. The key objectives of the project are as follows:

• To identify, map and collate relevant information on all ecologically significant fish barriers in the Burdekin Dry Tropics Region;
• To examine the feasibility and risks associated with a removal or modification program for priority fish barriers;
• To determine the efficacy of barrier removal or modification in the protection of native fish species; and
• To prioritise fish barriers for removal or modification and to establish planning level cost estimates.
  

Phase 2 - Fish Passage Restoration

On ground works will be undertaken to restore fish movement through the priority barriers identified by the assessment study  in Phase 1.
