Early Life History of the ‘Irukandji’ Jellyfish Carukia barnesi
Adult medusae of Carukia barnesi were collected near Double Island, North Queensland Australia and production was in the form of monodisc strobilation, which left behind polyps able to continue asexual reproduction.
A new method for resolving uncertainty of energy requirements in large water breathers: the ‘mega‐flume’ seagoing swim‐tunnel respirometer
The design and testing of a new method for measuring metabolic rates of large water‐breathing animals: a c.
Seasonality in Polyps of a Tropical Cubozoan: A latina nr mordens
To elucidate the relationship between medusae periodicity and polyp ecology, polyps were exposed to thermal and osmotic treatments in order to determine the theoretical environmental limits to their distribution and fecundity was found to be positively correlated with feeding frequency.
A review of juvenile redclaw crayfish Cherax quadricarinatus (von Martens, 1898) aquaculture: global production practices and innovation
This paper reviews the literature concerning redclaw juvenile production and provides a status report of current practices and innovations that may support further expansion of redclaw aquaculture.

The results indicate that adult medusae of C. barnesi are not opportunistically grazing in the water column, but instead utilize sophisticated prey capture techniques to specifically target larval fish.
Thermal and Osmotic Tolerance of ‘Irukandji’ Polyps: Cubozoa; Carukia barnesi
The thermal and osmotic tolerance of the polyp stage of the Irukandji jellyfish Carukia barnesi is explored, which provides new insights into potential polyp habitat suitability and temperature, salinity, feeding frequency, and combinations thereof did not induce medusae production, suggesting that this species may use a different cue, possibly photoperiod, to initiate medusAE production.

This study provides evidence to suggest drone surveys overcome obstacles that traditional surveys can’t, with respect to species deemed logistically difficult and open scope for further ecological investigations on such species.
Morphology and Weight-length Relationships for the First Six Instars of Cherax quadricarinatus (von Martens, 1868)
Branchial water uptake during ecdysis has been proposed as a route for dissolved organic matter or small particulate matter to be acquired by the crayfish during the lecithotrophic, nonexogenous feeding stages, as an additional food source that might further enhance growth and survival.
Determining Suitable Thermal Regimes for Early Instar Redclaw Juveniles, Cherax quadricarinatus (von Martens, 1868) (Decapoda, Parastacidae), for a Proposed Nursery Phase
This study quantified the effect of temperature on the growth and survival of redclaw juveniles for a 22-day nursery phase and suggests a water temperature of 22°C is optimal for survival and growth in a nursery phase.
