[ABSTRAK
Telah dilakukan penelitian mengenai identifikasi spesies dan distribusilarva udang mantis di Teluk Banten selama bulan Oktober 2013--November 2013.Penelitian bertujuan untuk mengukur efektivitas aplikasi DNA barcoding dalamidentifikasi larva udang mantis dan mempelajari pola distribusinya di TelukBanten. Larva udang mantis sebanyak 138 individu dikoleksi denganmenggunakan jaring larva dengan besar mulut 30x30 cm2 dan besar jaring sebesar500 μm dari 6 stasiun penelitian. Daerah COI sebagai penanda DNA barcodingefektif dapat digunakan untuk identifikasi larva udang mantis dengan variasiintraspesies sekuen COI berkisar antara 0,7--2,4%. Distribusi larva udang mantisberpusat di Stasiun 4 yang ditandai dengan tingginya kelimpahan larva udangmantis pada lokasi tersebut (P<0,005; ANOSIM). Ordinasi NMDS danklusterisasi berdasarkan jarak Bray-Curtis menunjukkan distribusi larva udangmantis dipengaruhi oleh kondisi perairanTeluk Banten. Faktor lingkungan yangmemengaruhi kelimpahan larva udang mantis adalah suhu, salinitas dan kecerahandengan nilai R2 adjusted sebesar 94,5% (P<0,05). Distribusi, kelimpahan, dankomposisi larva udnag mantis di Teluk Banten juga dipengaruhi oleh polaperilaku larva (vertical migration) dan arah arus yang memengaruhi perairanTeluk Banten. Distribusi kelimpahan larva pada lokasi penelitian selama bulanOktober--November 2013 bergerak kearah barat Teluk Banten.

ABSTRACT
Planktonic larvae of stomatopoda were collected at six stations in BantenBay from October 2013 to November 2013, aimed at assessing effectiveness ofusing COI gene for barcoding stomatopoda larvae and studying its distribution inBanten Bay. A total of 138 stomatopod larvae were obtained by deploying larvaltrap of 30x30 cm2 mouth diameters and 500 μm mesh size for approximately 10minutes just beneath the surface. Five species of stomatopod successfullyidentified using COI gene as barcode marker. Variation of intraspecies for COIgene based on Kimura 2-Parameter (K2P) were found to be ranged from 0,7% to2,4%. NMDS ordination and Bray-Curtis cluster shown that distribution ofstomatopod larvae affected by hydrodynamic on Banten Bay. Larvae abundance atsix stations in Banten Bay affected by temperature, salinity, and visibility withscore of adjusted R2 is 94,5% (P<0,05). Distribution, abundance, and diversity ofstomatopods larvae are affected by vertical migration and current on Teluk Bantenwater.;Planktonic larvae of stomatopoda were collected at six stations in BantenBay from October 2013 to November 2013, aimed at assessing effectiveness ofusing COI gene for barcoding stomatopoda larvae and studying its distribution inBanten Bay.
