We originally started the journey of creating new habitat options to satisfy our own requirements for habitat. We hypothesised that: (1) a wood-rich sub-reach would have greater diversity in physical habitat than woodless sub-reaches; (2) microhabitat cover requirements of crayfish need not only be provided by wood, but that; (3) a wood-rich sub-reach would This management plan is the product of a proactive, collaborative effort between FWC staff and Even experienced scholars struggle to complete a decent work in short order. Key words: Murray Crayfish, crustacea, Murray-Darling Basin, knowledge gaps Murray Crayfish (Euastacus armatus) is highly valued by recreational fishers in the southern Murray-Darling Basin, and is also listed as a threatened species across much of its range.

The first part of the day will cover a brief introduction to crayfish and their habitat requirements, the survey method and site selection. The fact their broad habitat requirements are similar to those of red swamp crayfish suggests the two species co-occur and perhaps compete for food and space at times. Not much is known about the habitat requirements of the Mimic Crayfish. For this project, two major ecotypes were defined and studied: wadeable streams, and primary burrowing crayfish habitat. Obligate crayfish burrow use and core habitat requirements of crawfish frogs .
