Length-frequency distributions show

Length-frequency distributions showing habitat preferences of A. percoides captured in regular
sampling sites in the Magela and Nourlangie Creek catchments are given in figure 107.
Magela catchment
The LFM of males and females differed by 20 mm LCF. This difference in length
corresponded to a trough in the overall length-frequency distribution; for ease of presentation
juveniles are defined as those fish less than 60 mm LCF (centre of trough) and adults as those
greater than 60 mm LCF.
Juvenile A. percoides were most frequently captured in sandy corridor waterbodies and, to a
lesser extent, in lowland backflow and floodplain billabongs. Very small juveniles were also
found in escarpment mainchannel waterbodies; these specimens were first observed grazing on
periphyton on partly submerged Pandanus aquaticus branches during the 1978 Late-dry season.
Small adult A. percoides were captured mainly in lowland sandy creekbeds and lowland
backflow billabongs; small numbers were also captured in corridor and floodplain billabongs
and escarpment mainchannel waterbodies. Larger adults were mainly captured in deeper and
more permanent waters such as escarpment mainchannel waterbodies and corridor and
floodplain billabongs; these habitats probably function as Dry season refuge areas for the
breeding populations of most species in the catchment.

Distribusi frekuensi panjang menunjukkan preferensi habitat A. percoides ditangkap di reguler
lokasi pengambilan sampel di Magela dan Nourlangie Creek DAS diberikan pada Gambar 107.
tangkapan Magela
The LFM dari pria dan wanita berbeda dengan 20 mm LCF. Perbedaan panjang
berhubungan dengan palung dalam distribusi frekuensi panjang keseluruhan; untuk kemudahan presentasi
remaja didefinisikan sebagai ikan yang kurang dari 60 mm LCF (pusat melalui) dan orang dewasa yang
lebih besar dari 60 mm LCF.
Juvenile A. percoides yang paling sering ditangkap di badan air koridor berpasir dan, pada
tingkat lebih rendah, di arus balik dataran rendah dan dataran banjir billabongs. Remaja sangat kecil juga
ditemukan di badan air lereng mainchannel; spesimen ini pertama kali diamati merumput di
perifiton pada sebagian terendam Pandanus cabang aquaticus selama 1978 Akhir-kering musim.
dewasa Kecil A. percoides ditangkap terutama dalam creekbeds berpasir dataran rendah dan dataran rendah
billabongs arus balik; jumlah kecil juga ditangkap di koridor dan billabongs dataran banjir
dan lereng mainchannel badan air. Orang dewasa yang lebih besar terutama ditangkap di dalam dan
perairan permanen lebih seperti badan air lereng mainchannel dan koridor dan
billabongs dataran banjir; habitat ini mungkin berfungsi daerah musim perlindungan sebagai kering untuk
populasi perkembangbiakan sebagian besar spesies di daerah tangkapan.
