Way Kambas National Park is one of the National Parks located in Lampung Province. This area has several types of wetland ecosystems, namely rivers, swamps, and mangroves. The condition of diverse mangrove ecosystems can affect the density and diversity of biota, one of which is macrozoobenthos that live in the region. The purpose of this study is to find out the relationship between mangroves and macrozoobenthos. The study was conducted in January 2021 at Mangrove Way Kambas National Park. Sampling was conducted at 6 stations with different mangrove density conditions, that was, sparse densities at stations I and station 4, as well as solid at stations 2, 3, 5, and 6. In addition to total organic matter, other environmental parameters were also observed including pH, salinity, temperature, dissolved oxygen, substrate type, brightness, and depth. Macrozoobenthos were found to be 12 species of macrozoobenthos namely Polymesoda expansa, Acetes indicus, Illyoplax pacifica, Asiminea brevicula, Terebralia palustris, Clithon oualeniense, Terebralia sulcata, Cerithidea quadrata, Pomacea canaliculata, Telescopium telescopium, Episesarma versicolor, and Planaria torva in 6 research stations. As for the positive correlates with macrozoobenthos density, were pH, salinity, and total organic matter (TOM).

Abstract. The snubnose pompano Trachinotus blochii is one of the important commercial fishery commodity in the Indonesian market. The increasing of the market demand has led some efforts to increase the production of this fish. So do the increasing need for green mussels Perna viridis meat. Therefore it is necessary to evaluate the performance of both species in the polyculture system by using raft culture. This study aims to compare the growth performance of snubnose pompano cultivated on a monoculture system and polyculture within green mussels in a raft system. The parameter observed was the differences in the growth performance of both species and the increase in total weight and survival (SR) of the fish. The results showed that the growth of snubnose pompano did not provide a significant difference in the growth of both cultivating systems whether in monoculture or polyculture system, likewise the shell length and width of the green mussels. We conclude that it is profitable to cultivate both organisms on a polyculture system because it can harvest both green mussels and snubnose pompano together in a period.Keywords: Snubnose pompano, green mussel, monoculture, polyculture, raft, growth Abstrak. Permintaan pasar terhadap daging ikan bawal bintang semakin meningkat begitupun dengan daging kerang hijau sehingga diperlukan suatu upaya rekayasa teknologi budidaya. Salah satunya adalah dengan menerapkan sistem polikultur dalam keramba jaring apung. Penelitian ini bertujuan membandingkan faktor pertumbuhan ikan bawal bintang dan kerang hijau yang dibudidayakan dengan sistem monokultur dan polikultur. Pengamatan dilakukan pada perbedaan pertumbuhan ikan dan kerang hijau, juga pada mutlak serta survival rate (SR). Hasil penelitian menunjukkan bahwa pertumbuhan panjang dan lebar bawal bintang tidak memberikan perbedaan pertumbuhan secara nyata baik pada perlakuan monokultur dan polikultur. Begitupun dengan pertumbuhan kerang hijau sehingga sistem polikultur lebih menguntungkan untuk dilakukan karena bisa memanen kerang hijau dan ikan bawal bintang sekaligus.Kata Kunci: kerang hijau, ikan bawal bintang, monokutur, polikultur, pertumbuhan, KJA.

Gillnet fisheries play an important role in supporting the local economy and the welfare of coastal communities. However, fishermen still face challenges related to unequal access to livelihood assets and high vulnerability to external factors such as seasonal changes, catch fluctuations, market pressures, and environmental conditions. This study aimed to analyze the level of vulnerability, identify livelihood assets, and formulate strategies for sustainable livelihood development among gillnet fishing communities. The study was conducted in Margasari and Muara Gading Mas Villages in September 2025 using a mixed-method approach, combining questionnaires, in-depth interviews, and field observations. Samples were selected through purposive sampling, and data were analyzed using descriptive quantitative and qualitative methods supported by a Likert scale. The results showed that fishermen’s vulnerability is relatively high (54.5%), affecting income stability. Social (81.4%) and natural (78.7%) assets are relatively strong, while human (38.6%), physic (48.3%), and financial (43.20%) assets remain relatively low. Limited education, lack of training, and restricted access to financial resources are the main constraints, leading to low adaptive capacity and limited livelihood diversification. Recommended strategies include improving human resource capacity, strengthening access to financial capital, and developing livelihood diversification based on local potential. These efforts are expected to enhance household economic resilience and support sustainable livelihoods among gillnet fishing communities.
