“…The research result by [8] In Nusa Laut water, found that fish eggs dominated the meroplankton group (May 2009, while in April 2014 it was dominated by echinoderm larvae. In Jakarta Bay (April and June), meroplankton from the shrimp group (crustaceans) dominated in the waters of the Jakarta Bay [10]. Based on Figure 3 and 4, the Echinoderm larvae group dominated the meroplankton abundance in the IAB.…”

“…Meroplankton studies have been carried out in several locations in Indonesian waters, for example by Nusalaut (Maluku) waters [8], Ambon Bay [9], Jakarta Bay [10], Pulau Seribu [11]. Research on Meroplankton in Ambon Bay had previously been carried out by [9] in transitional season 1 and east monsoon (may to June) which focused on the waters of the IAB.…”

Here we present the study of meroplankton in Ambon Bay. This study aims to determine the composition and abundance of meroplankton in Ambon Bay. Sixteen stations (eight in the IAB and eight in the OAB) were sampled in March 2022. A plankton sampling was carried out using a plankton net with a mesh size of 300 microns and a diameter of 30 cm drawn at a depth of 10 meters to the surface. The study results showed that the meroplankton in Ambon Bay at the time of observation consisted of fish larvae, fish eggs, Echinodermata larvae, gastropoda larvae,cirripedia larvae, stomatopoda larvae, bracyura larvae (megalopa), bracyura larvae (zoea), nauplius crustacea, sea anemone larvae, other crustacea larvae and annelida larvae. The abundance of meroplankton in the IAB is higher than in the OAB. ANOSIM showed significant differences between IAB and OAB (p <0.05). SIMPER analysis showed that the mean dissimilarity between IAB and OAB was of 56.16%. The meroplankton group was dominated by Echinodermata larvae, which were found to dominate at all research stations, especially in the inner bay of Ambon, with the highest abundance found at station 4, which was 120.31 ind.m−3.

“…Wilayah perairan Teluk Jakarta, termasuk didalamnya Kepulauan Seribu telah lama dikenal sebagai pemasok hasil-hasil perikanan bagi wilayah DKI Jakarta. Nastiti et al (2016) menyatakan bahwa perairan Teluk Jakarta berfungsi sebagai daerah asuhan dan pemijahan bagi berbagai jenis biota laut. Hal ini ditunjukkan dengan ditemukannya meroplankton seperti ikan, telur, udang dan kepiting.…”

Payang merupakan alat tangkap dengan laju tangkap relatif tinggi di Teluk Jakarta, sedangkan bagan tancap dikenal kurang selektif karena hasil tangkapannya didominasi oleh ikan berukuran kecil baik jenis pelagis maupun demersal. Penelitian ini dilaksanakan dengan metode fishing experiment pada payang dan bagan tancap. Hasil penelitian menunjukkan bahwa hasil tangkapan payang dan bagan tancap didominasi oleh jenis ikan demersal namun proporsi tangkapannya tidak jauh berbeda dengan jenis ikan pelagis. Komposisi ikan hasil tangkapan payang pada Agustus dan Oktober didominasi oleh jenis ikan pelagis, sedangkan pada bulan Desember didominasi oleh jenis ikan demersal. Nilai laju tangkap payang untuk jenis ikan pelagis ditemukan tinggi pada Agustus dan Oktober disebabkan oleh dominasi ikan cekong (Sardinella lemuru) dalam jumlah besar. Komposisi ikan hasil tangkapan bagan tancap pada Mei didominasi oleh jenis ikan demersal, sedangkan pada Oktober didominasi oleh jenis ikan pelagis. Daerah penangkapan payang meliputi perairan Pulau Damar, Pulau Bendera, Muara Pecah, Muara Angke, Pulau Onrust, Pulau Putri, Kronjo, sedangkan daerah penangkapan bagan tancap terkonsentrasi di sebelah barat perairan Teluk Jakarta, sekitar Pulau Kayangan, Pulau Bidadari dan Pulau Onrust. ABSTRACT Payang, a mini danish seine, is an artisanal fishing gear that has high catchability rate. Like payang, another dominant fishing gear in Jakarta Bay, the lift net, is also known as unselective fishing gear since small fish dominate its catch. This research uses the fishing experiment method with payang and lift net to figure out the gears' catch composition and catch rate. The result shows both fishing gears predominately caught the demersal fish group, but its proportion does not much from the pelagic group. During August and October, the catch composition of payang was dominated by pelagic fish, while demersal fish was caught mostly in December. The high catch rate for pelagic fish was recorded in August and October since cekong fish (Sardinella lemuru) dominated the cath. The catch composition of lift net was dominated by demersal fish during May, while pelagic fish were mostly captured in October. Payang’s fishing ground includes Pulau Damar waters, Pulau Bendera, Muara Pecah, Muara Angke, Pulau Onrust, Pulau Putri, and Kronjo, while the lift net dominates the western part of part of Jakarta Bay including Pulau Kayangan, Pulau Bidadari, and Pulau Onrust.

Reklamasi pantai Teluk Jakarta merupakan rencana pemerintah yang ditujukan untuk mengendalikan banjir di Kota Jakarta dan pengembangan area bisnis yang tumbuh semakin pesat. Reklamasi dilaksanakan dengan membangun tanggul raksasa sepanjang 60 km di Teluk Jakarta dan pembangunan 18 pulau kecil di depan pantai. Reklamasi pantai dapat memberikan dampak terhadap lingkungan perairan dan perikanan. Dalam rangka pelaksanaan pengelolaan perikanan berkelanjutan, maka perlu dilakukan analisis dampak reklamasi terhadap kondisi kualitas air dan perikanan di teluk Jakarta. Tujuan dari penelitian ini adalah untuk menganalisis dampak reklamasi terhadap kondisi kualitas air dan perikanan melalui analisis data primer dan sekunder. Hasil penelitian menunjukkan bahwa reklamasi pantai menambah tekanan terhadap kondisi lingkungan perairan yang diindikasikan oleh penurunan kecerahan perairan, salinitas dan nilai indeks keanekaragaman fitoplankton dan makrozoobenthos. Reklamasi pantai akan menghilangkan daerah penangkapan sero, bagan tancap dan keramba kerang hijau, yang mengakibatkan terjadinya penurunan produksi ikan. Potensi penurunan produksi ikan yang akan terjadi sekitar 82,2 ton/tahun. Di sisi lain, bagian timur Teluk Jakarta mempunyai potensi sebagai daerah asuhan ikan dan udang. Reklamasi pantai akan mengganggu fungsi ekologis Teluk Jakarta sebagai daerah asuhan ikan dan udang. Reklamasi Teluk Jakarta dapat dilaksanakan dengan disertai upaya pengelolaan kawasan untuk menjaga peran dan fungsi ekologisnya.Coastal reclamation in Jakarta Bay is one of government planning as flood disaster management and business development area that has been grow very fast. A 60 km of giant sea wall and 18 small reclamation islands in Jakarta Bay will be developed. Coastal reclamation will have an impact on environment and fisheries. In the context of sustainable fisheries management, an impact analysis of coastal reclamation on water quality and fisheries are needed. Research objectives are to analyze the coastal reclamation impact on water quality and fisheries in Jakarta Bay, through primary and secondary data analysis. Results showed that coastal reclamation adds pressure to water quality indicated by decreasing the water transparency, salinity and the value of diversity index of phytoplankton and makrozoobenthos. Coastal reclamation will eliminate the fishing area of set net (stationary fishing gear), stationary lift net and green mussel trap nets, resulting in fish production loss. The potential decrease of fish production is about 82,2 ton/yr . On the other side, Jakarta Bay has a potential area of fish and shrimp nursery ground in the eastern part of the bay. Coastal reclamation will disrupt its ecological function as nursery ground. Reclamation of Jakarta Bay can be carried out along with area management to maintain its ecological role and function.
