ABSTRAKTelah dilakukan penelitian mengenai identifikasi spesies dan distribusi
larva udang mantis di Teluk Banten selama bulan Oktober 2013--November 2013.
Penelitian bertujuan untuk mengukur efektivitas aplikasi DNA barcoding dalam
identifikasi larva udang mantis dan mempelajari pola distribusinya di Teluk
Banten. Larva udang mantis sebanyak 138 individu dikoleksi dengan
menggunakan jaring larva dengan besar mulut 30x30 cm2 dan besar jaring sebesar
500 μm dari 6 stasiun penelitian. Daerah COI sebagai penanda DNA barcoding
efektif dapat digunakan untuk identifikasi larva udang mantis dengan variasi
intraspesies sekuen COI berkisar antara 0,7--2,4%. Distribusi larva udang mantis
berpusat di Stasiun 4 yang ditandai dengan tingginya kelimpahan larva udang
mantis pada lokasi tersebut (P<0,005; ANOSIM). Ordinasi NMDS dan
klusterisasi berdasarkan jarak Bray-Curtis menunjukkan distribusi larva udang
mantis dipengaruhi oleh kondisi perairanTeluk Banten. Faktor lingkungan yang
memengaruhi kelimpahan larva udang mantis adalah suhu, salinitas dan kecerahan
dengan nilai R2 adjusted sebesar 94,5% (P<0,05). Distribusi, kelimpahan, dan
komposisi larva udnag mantis di Teluk Banten juga dipengaruhi oleh pola
perilaku larva (vertical migration) dan arah arus yang memengaruhi perairan
Teluk Banten. Distribusi kelimpahan larva pada lokasi penelitian selama bulan
Oktober--November 2013 bergerak kearah barat Teluk Banten.
ABSTRACTPlanktonic larvae of stomatopoda were collected at six stations in Banten
Bay from October 2013 to November 2013, aimed at assessing effectiveness of
using COI gene for barcoding stomatopoda larvae and studying its distribution in
Banten Bay. A total of 138 stomatopod larvae were obtained by deploying larval
trap of 30x30 cm2 mouth diameters and 500 μm mesh size for approximately 10
minutes just beneath the surface. Five species of stomatopod successfully
identified using COI gene as barcode marker. Variation of intraspecies for COI
gene based on Kimura 2-Parameter (K2P) were found to be ranged from 0,7% to
2,4%. NMDS ordination and Bray-Curtis cluster shown that distribution of
stomatopod larvae affected by hydrodynamic on Banten Bay. Larvae abundance at
six stations in Banten Bay affected by temperature, salinity, and visibility with
score of adjusted R2 is 94,5% (P<0,05). Distribution, abundance, and diversity of
stomatopods larvae are affected by vertical migration and current on Teluk Banten
water.;Planktonic larvae of stomatopoda were collected at six stations in Banten
