| Abstract |
Features of the life history of Himantura astra from north-east Australia were examined including its age and growth, reproduction and diet. Centrum edge and marginal increment ratio analyses were used to validate annual band formations with the Gompertz growth function providing the best fit to male (W(D∞) = 722·7 mm, k = 0·104) and female (W(D∞) = 821·8 mm, k = 0·073) disc width (W(D))-at-age data. At 29 years, the maximum age of females was higher than males (18 years). Sizes at 50% sexual maturity (W(D50)) for males and females were 469·3 and 462·3 mm, respectively. Ages at sexual maturity (A(M50)) were reported at 7·32 (males) and 8·67 (females) years. An index of relative importance (I(RI)) revealed carid shrimps (77·9%), brachyurans (12·1%) and stomatopods (4·9%) as the most important prey groups, with prey diversity increasing with W(D) from 0·92 to 1·63 (Shannon-Weiner index). This study provides significant insights into the biology of H. astra and contributes to the ongoing development of fisheries-based risk assessments for this species. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 22 January 2013.
All research outputs
#17,285,668
of 25,373,627 outputs
Outputs from Journal of Fish Biology
#3,685
of 5,120 outputs
Outputs of similar age
#95,079
of 120,717 outputs
Outputs of similar age from Journal of Fish Biology
#14
of 18 outputs
Altmetric has tracked 25,373,627 research outputs across all sources so far. This one is in the 21st percentile – i.e., 21% of other outputs scored the same or lower than it.
So far Altmetric has tracked 5,120 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.4. This one is in the 22nd percentile – i.e., 22% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 120,717 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 13th percentile – i.e., 13% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 18 others from the same source and published within six weeks on either side of this one. This one is in the 22nd percentile – i.e., 22% of its contemporaries scored the same or lower than it.
