[ABSTRAK Penelitian komunitas ikan yang tertangkap dengan jaring push net dankaitannya dengan produksi serasah hutan mangrove di Pulau Panjang, TelukBanten telah dilakukan pada bulan Oktober?Desember 2014 saat pasangpurnama. Tujuan penelitian untuk melihat keanekaragaman dan komunitas ikanserta mengetahui besarnya serasah yang dilepas ke perairan laut dan hubunganantara C, N, P serasah dengan C, N, P Chandidae (famili ikan dominan dalampenelitian). Metode penangkapan ikan dengan push net secara manual danpemasangan perangkap serasah berupa paralon yang mengarah ke perairan laut diStasiun 1 dan 2. Hasil tangkapan ikan yaitu 1.770 individu (14 famili, 16 marga,dan 22 spesies). Jumlah terbanyak di Stasiun 1 (1.213) dan bulan November(749). Nilai H? di Stasiun 1 (0,71) dan 2 (0,81) adalah rendah dan sedang,didukung rendahnya nilai E dan tingginya D. Sebanyak 51% ikan yangtertangkap adalah Ambassis gymnocephalus dari famili Chandidae. Ikankomersial yang tertangkap yaitu dari famili Mugilidae dan Serranidae. Mayoritasikan yang tertangkap juga merupakan ikan penetap sejati (true resident) yaituberjumlah 1.248 ekor. Biomassa serasah dan Chandidae terbesar yaitu di bulanDesember (219,49 g dan 75,85 g). Sementara Stasiun 1 memberikan biomassaterbesar untuk serasah (162,99 g) dan Stasiun 2 untuk Chandidae (19,14 g). Nilaiserasah terbanyak yang dilepas ke laut yaitu pada bulan Desember di Stasiun 1(47,47 g/m³/s). Nilai koefisien relasi C, N, P serasah dengan C, N, P Chandidaememberikan hasil yang sama yaitu 0,999. Model regresi yang terbentuk berturutturutyaitu Chandidae = 0,889 C Serasah, Chandidae = 11,367 N Serasah, danChandidae = 5,407 P Serasah. ABSTRACT The research of fish community and its correlation with the production ofmangrove forest litter in Panjang Island, Banten Bay had been conducted fromOctober to December 2014 while spring tide. The research?s aim was to know thefish diversity and fish community, to identify mangrove litter?s value to the seaand correlation between C, N, P of mangrove litter and C, N, P of Chandidae (thebiggest fish family captured). The method was used push net manually active andalso water pipes were put to captured mangrove?s litter to the sea at Station 1 and2. In total, 1770 species were captured (14 families, 16 genera, and 22 species),the most large number were at Station 1 and in November (1.213 and 749individus). H? value at Station 1 was low (0,71), meanwhile at Station 2 wasmoderate (0,81). It supported by low E value. 51% fish captured was Ambassisgymnocephalus from Chandidae family. Economic value fish captured wereMugilidae and Serranidae. Mostly fish captured also were true resident fish(1.248). The biggest biomass of mangrove litter was been at Station 1 (162,99 g),while Chandidae was been at Station 2 (19,14 g). The biggest removed mangrovelitter to the sea water was in December and Station 1 (47,47 g/m³/s). The Pearsoncorrelation from C, N, P of mangrove litter and C, N, P of Chandidae gave thesame value (0,999). The model of Linear Regression were Chandidae = 0,889 CMangrove litter, Chandidae = 11,367 N Mangrove litter, dan Chandidae = 5,407P Mangrove litter., The research of fish community and its correlation with the production ofmangrove forest litter in Panjang Island, Banten Bay had been conducted fromOctober to December 2014 while spring tide.
