Penelitian tentang aspek biologi tenggiri di Indonesia masih jarang dilakukan, padahal upaya pemanfaatannya telah lama dilakukan oleh nelayan. Ikan tenggiri di Teluk Kwandang penangkapannya dilakukan dengan alat tangkap purse seine dan pancing ulur. Data-data terkait biologi reproduksi ikan tenggiri di perairan Kwandang belum tersedia dengan baik, oleh sebab itu perlu dilakukan kajian yang lebih lengkap. Pelabuhan Perikanan Pantai Kwandang merupakan pelabuhan baru, sehingga informasi terkait perikanan tenggiri pada khususnya sangat bermanfaat dalam pendataan dan rencana pengelolaannya. Penelitian telah dilakukan pada Februari-Desember 2012 di perairan Teluk Kwandang, Kabupaten Gorontalo Utara, dengan tujuan mengkaji aspek perikanan meliputi struktur ukuran, panjang bertama kali tertangkap dan biologi reproduksi meliputi: Tingkat Kematangan Gonad, Gonado Somatic Index (GSI), nisbah kelamin, panjang pertama kali matang gonad, diameter dan jumlah telur. Dari penelitian ini diperoleh struktur ukuran pada kisaran 25-138 cmFL, dengan rata-rata modus 60 cmFL. Panjang pertama kali tertangkap dengan purse seine dan pancing ulur masing-masing 64,7 cmFL dan 71,9 cmFL. Tingkat Kematangan Gonad ikan tenggiri didominasi oleh gonad belum matang 61,2%, dan kondisi matang gonad 38,8%. Puncak Gonado Somatic Index (GSI) terjadi pada bulan Mei, sehingga ikan tenggiri di Teluk Kwandang diduga memijah pada Mei-Juli. Nilai GSI mencapai puncaknya pada panjang ikan 98 cmFL, dan akan turun pada panjang ikan lebih dari 100 cmFL. Panjang pertama kali matang gonad ikan tenggiri adalah 80,4 cmFL, pada kisaran 79,3-81,6 cmFL. Jumlah telur ikan tenggiri berkisar 417.360-9.476.520 butir pada panjang ikan 65-103 cmFL. Berdasarkan perkembangan diameter telur setiap bulan menunjukkan tipe pemijahan ikan tenggiri adalah asynchronous dengan pola pemijahan partial spawner.The study on biological aspects of spanish mackerel in Indonesia is uncommon, whereas the exploitation have been conducted historically. Spanish mackerel in the Kwandang Bay caught by purse seiner and handliner. The reproductive biology of mackerel fish in Kwandang waters was unavailable, therefore more study needed. Kwandang is a new port, so the information related to Spanish mackerel in particular is very useful in data collection and management plan. This research aims to assess biological aspect such as the size structure, the length at first captured and reproductive biology aspects (gonad maturity stage, Gonado Somatic Index (GSI), sex ratio, length at first maturity, number and diameter of oosit). The study was conducted in February-December 2012 in the Kwandang Bay waters, North Gorontalo regency. The results showed that the size structure ranged between 25-138 cmFL, with average mode 60 cmFL. The length at first capture caught (Lc) with purse seine and handline by 64,7 cmFL and 71,9 cmFL, respectively. The gonad maturity stage of the was dominated by 61,2% of immature and 38,8% of mature gonad. Gonado Somatic Index (GSI) peak was reached in May, and from this GSI value it is concluded that the Spanish mackerel spawned in May-July. The maximum GSI reached at 98 cmFL and decreased at fish length exceeded 100 cmFL. Length at first maturity (Lm) of the gonad was approximately 80,4 cmFL, within the size range between 79,3-81,6 cmFL. The number of spanish mackerel oosit ranged between 417.360-9.476.520, with size ranged between 65-103 cmFL. The monthly fluctuations of oosit diameter implied that spawning type of spanish mackerel was asynchronous with partial spawner spawning pattern.

This study is the first review of current research on microplastics (MPs) in the marine environments at the national scale in Indonesia from 2015 to 2022. This review was conducted to measure the environmental risk and highlight the waste management issue in Indonesian waters. Our literature study found that: (1) the MPs research was mainly conducted in the western part of Indonesia, especially in Java Island; (2) current research has primarily focused on coastal waters (98%) rather than the deep-sea area (2%); (3) the comparability of data is still hampered by difference in quality, about 67% of articles published have not carried out the polymer confirmation; (4) MPs concentrations reported on the articles that did not carry out the polymer identification tended to report higher MPs concentrations. Finally, we propose to have a standard guideline for MPs analysis at a national level and to do more research in the eastern part of Indonesia and deep-sea areas. Further research is required to fill research gaps on plastic distribution and density in deep-sea areas in the eastern part of Indonesia.

The current climate change is caused by anthropogenic activities involving energy and industry usage that affect the temperature and climate of the Earth. The Paris Agreement on climate change is a commitment by some countries to act to address climate change by developing sustainably and emitting low levels of carbon dioxide (CO2). Changes in the oceans include temperature increases, acidification, and changes in currents, leading to decreased productivity in fishing and aquaculture. Integrated mangrove shrimp farming, known as silvofisheries, has been recognized as environmentally friendly cultivation. The implementation of silvofishery is a form of mangrove ecosystem management that integrates ecology and economics. An economic and ecological valuation is needed in the Vannamei shrimp farming business. Therefore, this study aims to build an economic model of mangroves and shrimp farming. The data were analyzed and simulated using Systems Dynamic. Based on Business as Usual (BAU) simulation predictions for the 2023 mangrove area of 267 hectares, the best scenario for the mangrove area of 2033 is 1,770 hectares, the total economic value of shrimp of Rp 49,300,000,000 and the total economic value of mangrove is Rp 77,175,000,000. This research results in a potential trade-off between intensive shrimp farming businesses and mangrove rehabilitation to maintain a business's sustainability and the environment's carrying capacity.

Aquaculture practices in developing countries, particularly Indonesia, are currently operating without effective control measures, leading to high tidal and other climate-related issues. Therefore, this study aimed to modify Coastal Vulnerability Index (CVI) assessment to evaluate the physical vulnerability of coastal areas in Indramayu Regency, West Java (62 sections) to tidal flooding (Rob). A total of 6 primary characteristics, including geomorphology, beach slope, water level rise sea, coastline alterations, tidal range, and high tide, as well as 2 additional parameters, namely land cover and mangrove breadth, were used for analysis. Based on the evaluation, CVI was divided into four groups, including (1) low, (2) moderate, (3) high, and (4) very high. The results showed that Indramayu District struggled to recover from tidal flooding, with 24.56%, 22.13%, 41.03%, and 12.28% being placed in the very high, high, moderate, and low categories. This underscored the role of local governments in improving coastal communities' capacity to respond to tidal flooding disasters. Furthermore, the results were expected to be used by local governments to enhance disaster mitigation systems, particularly for coastal areas in developing nations with comparable ecological conditions.
