Penelitian ini bertujuan untuk mengetahui komposisi ikan hasil tangkapan bubu lipat dan mengetahui pengaruh penggunaan berbagai umpan terhadap hasil tangkapan bubu lipat di Desa Paljaya, Kabupaten Bekasi. Penelitian dilaksanakan pada bulan Desember 2015 – Juli 2016, dilakukan dengan kegiatan uji coba penangkapan (experimental fishing). Pengoperasian bubu lipat dilakukan secara rawai sejumlah 60 bubu. Jenis umpan yang diberikan yaitu berupa umpan ikan tanpa perlakuan/kontrol, umpan ikan yang direndam terasi, dan umpan yang direndam asap cair. Bubu dipasang pada sore hari dan hasil tangkapan diambil pada pagi di hari selanjutnya. Data yang dikumpulkan yaitu total tangkapan, jumlah spesies, panjang dan berat ikan. Data yang dianalisis berupa jumlah dan berat hasil tangkapan. Komposisi hasil tangkapan bubu lipat terdiri dari 6 jenis spesies, yaitu 41% rajungan (Portunus sp.), 24% kepiting tapal kuda (Carcinosscorpius sp.), 9% udang jerbung (Penaeus sp.), 1% ikan sembilang (Plotosus sp.), 18% kepiting bakau (Scylla sp.), 7% kepiting batu (Eurytium sp.). Hasil penelitian menunjukkan tidak ada perbedaaan secara nyata pada total jumlah dan berat ikan. Umpan dengan perlakuan asap cair mendapatkan hasil berat tangkapan 3445 gr dengan laju tangkap 344,5 gr/trip, hasil berat tangkapan umpan kontrol didapatkan sebesar 1907 gr dengan laju tangkap 158,6 gr/trip, dan hasil tangkapan umpan dengan perlakuan terasi sebanyak 1586 gr dengan laju tangkap 190,7 gr/trip.

The purpose of this research was to know the catch composition of trap and the different baits operated in Paljaya bay, Bekasi Regency. This research was conducted during December 2015 – July 2016 using experimental fishing folding trap. There were 60 traps used for this research, which was arranged linearly by holding in a plastic rope. The treatment used was namely traps untreatment fish, fish marinated shrimp paste, and fish soaked liquid smoke. The baits were put into the traps approaching the setting in the evening, and than the fish were collected in the following day. The data collected namely total fish traps, species number, individual weight and length. The data was subjected to analize on variety number and weight. The result showed that the catch composition of folding trap consisted of 6 species which was 41% Portunus sp., 24% Carcinosscorpius sp., 9% Penaeus sp., 1% Plotosus sp., 18% Scylla sp., 7% Eurytium sp. There was not significantly difference on weight and fish number among treatments. Baits with liquid smoke treatment got the catch weight of 3445 gr and with a catch rate of 344.5 gr/trip. The control bait was obtained the catch weight of 1907 gr with a catch rate of 158.6 gr/trip and the catch bait shrimp treated got as much as 1586 gr with a catch rate of 190.7 gr/trip.
