Ecology and herbicide tolerance of the native weeds that cause pimelea poisoning
No full textThree annual species of native Pimelea (Thymelaeaceae) cause intermittent but serious problems for cattle producers in inland Australia. The causal toxin and related compounds have been known for decades but no well-defined relationship between the incidence and abundance of the plant in pastures and levels of animal morbidity has been established.
We report on early efforts to germinate the seeds reliably so that appropriate toxicity and herbicide trials can be conducted. A strong embryonic dormancy has been shown to exist in fresh seed, particularly in P. simplex. Also, germination and recruitment conditions for P. elongata are apparently very different to those favourable to recruitment of P. trichostachya, even though they often grow in close proximity
Queensland shark control program non-target statistics by year from 2001 onwards
No full textSpreadsheet of non-target species (bycatch) numbers in the Shark Control Program by species, date of capture, location, size and sex from 2001 onwards
The shark control program (SCP) relies on nets or drumlines, or a combination of both, to minimise the threat of shark attack on humans in particular locations. Following is information on numbers and locations of sharks that have been caught by the SCP.
It is important to reduce the inadvertent impacts of the SCP on other marine animals (bycatch) without compromising human safety. Bycatch levels are carefully monitored and research is focused on minimising impacts on non-target species.
This dataset contains details of non-target numbers in the Shark Control program by species, date of capture, and location from 200
Uncertainty in length measurements of live coral trout: implications for compliance and enforcement of minimum legal size limits.
Full text linkReport on evidence of shrinkage of live coral trout during professional fishing operations on the Great Barrier Reef in 2000. Excel data includes the following fields:

Column B. Bin (1-8, container the fish was held in during the experiment)
Column C. Measure (1-7, number of the measurement of each fish)
Column D. Observer (1 or 2, making the measurement)
Column E. Time 2
Column F. Time (time of the day the measurement was made)
Column G. FL (Fork Length)
Column H. TL (Total Length)
Column I. Difference (difference in length between measures)
