This study aims to determine the conditions of tuna utilization, and to analyze the monitoring of tuna fisheries resources in preventing IUU fishing in Seram Sea Waters. Methods This research uses descriptive methods including primary and secondary data. Primary data comes from tuna fishermen respondents, fisheries monitoring agencies using purposive sampling and in-depth interviews, secondary data through literature studies. The results showed that the average tuna production in West Seram Regency was 4.10%, yellowfin tuna was 0.20%, the average CPUE of handline tuna fishermen was 505.86 kg/month/unit. The institutional capacity of fisheries supervisors needs to be improved, even though the vessel compliance indicator reaches 136%. Fishery violations during 2016-2018 are: violations of fishing routes and areas, violations of VMS, violations of fishing permits, and prohibitions on fishing by foreign people or vessels.

Our research aims to determine the shift in the catch of beach seine according to the perception of fishermen, to determine the catch of beach seine from September to October 2021, and to compare the catch in the same month with different years. The method of collecting data is through interviews, observations, and literature studies, then the results are analyzed descriptively and presented in the form of tables and figures. The results of the interview show that the number of beach seine and their catches in TAD is decreasing (number and types of fish). The results of two months of observation in 2021 for 31 trips, found only 15 species of fish with a total of 7257 individuals, and dominated by Stolephorus indicus 59.3%, Encrasicholina heteroloba 16.6% and Sardinella fimbriata 10.9%. The average length of S. indicus is 3.9 cm in the range of 2.1-6.7 cm and weighs 1.2 g (0.1-1.4 g). The results of beach seine monitoring in TAD showed a decrease in fish species by 29.41%, which is now dominated by S. indicus but with smaller body sizes, so it is necessary to conduct continuous research related to the ecobiology of the three types of fish that dominate the catch of the beach seine, as efforts to evaluate and monitor the use of fish resources in TAD sustainably and responsibly.

Flying fish Cypselurus poecilopterus is a small pelagic fish resource that plays an important ecological and economic role. However, information regarding the structure of its stock in East Indonesian waters is still limited. This study aims to identify stock structure based on morphometric, meristic approaches, and associated with environmental factors. Fish samples were taken during one fishing season (June-September) in 2015 and 2021 in the waters of West Papua and East Seram where the Lydakker line passes, using the method of observation and purposive sampling, then the data were analyzed descriptively and t-test. The results of observations on 23 morphometric characters and 5 meristic features showed a significant difference, so it is estimated that flying fish stocks are composed of 2 sub-populations. Differences in morphometric and meristic parameters are affected by different environmental conditions in the two waters. This information is expected to be useful for the management and sustainable use of flying fish resources.

Intensified utilization of scad fish and frequent catches of immature fish have disrupted the recruitment of young fish in the wild. This study aims to analyze the length-weight relationship and growth patterns of scad fish. Data were collected at the Fish Auction Place (FAP) of Waai Port, Central Maluku, from February to April 2024. Scad fish samples were measured for length and weight and analyzed using linear regression and multiple analysis to determine the length-weight relationship, with Von Bertalanffy analysis used to examine growth patterns. The study found a coefficient value (b) of 2.6017, indicating that the fish's length growth is faster than its weight increase, showing negatively allometric growth. The growth coefficient (K) is 0.061613 per year, with an asymptotic length of 37.44 cm. The (t0) value, indicating the age when fish length is close to zero, is 0.43 years. These findings suggest that scad fish from this population grow more in length than in weight. This has implications for fisheries management, which must regulate scad fish capture and utilization to prevent disrupting the recruitment and growth of young fish populations. Sustainable management practices are essential to maintain scad fish stocks and the balance of aquatic ecosystems in the region. ABSTRAK Peningkatan upaya pemanfaatan ikan layang yang intensif dan hasil tangkapannya lebih sering terdiri dari ikan-ikan yang belum mencapai ukuran matang gonad pertama kali, menyebabkan terganggunya proses rekruitmen ikan-ikan muda di alam. Penelitian ini bertujuan untuk menganalisis hubungan panjang-berat serta pola pertumbuhan ikan layang dari populasi tersebut. Pengumpulan data dilakukan di Tempat Pelelangan Ikan (TPI) Pelabuhan Waai, Maluku Tengah, selama periode Februari hingga April 2024. Sampel ikan layang yang didaratkan diukur panjang dan beratnya, kemudian dianalisis menggunakan metode regresi linier serta analisis berganda untuk mengkaji hubungan panjang-berat, serta menggunakan analisis Von Bertalanffy untuk memeriksa pola pertumbuhan ikan. Hasil penelitian menunjukkan bahwa nilai koefisien (b) sebesar 2,6017, yang mengindikasikan pertumbuhan panjang ikan lebih cepat dibandingkan dengan pertambahan beratnya atau pertumbuhan alometrik negatif. Selain itu, ditemukan bahwa koefisien pertumbuhan (K) adalah 0,061613 per tahun dengan panjang asimtotik mencapai 37,44 cm. Nilai (t0), yang menunjukkan usia pada saat panjang ikan mendekati nol, adalah 0,43 tahun. Berdasarkan temuan tersebut, dapat disimpulkan bahwa ikan layang dari populasi yang diteliti mengalami pertumbuhan panjang yang lebih dominan dibandingkan dengan peningkatan beratnya. Kondisi ini dapat berdampak pada strategi manajemen perikanan yang perlu memperhatikan pengaturan penangkapan dan pemanfaatan ikan layang agar tidak mengganggu proses rekruitmen dan pertumbuhan populasi ikan muda di alam. Pengelolaan yang berkelanjutan sangat diperlukan untuk memastikan kelestarian stok ikan layang serta keseimbangan ekosistem perairan di wilayah tersebut.

This research was carried out in the waters of Tulehu, Ambon Island between February and April 2020 to study the reproductive aspects of dark-banded fusilier (Pterocaesio tile) which covers sex ratio, gonad maturity level, gonado somatic index, and first maturity size. Dark-banded fusilier samples were collected on weekly interval from gill net fishers operating in the waters of Tulehu village. The fish samples collected were separated by sex, weighed and measured for its total length. All samples collected were then dissected to take the gonads, determined the gonad maturity stage (GMS) and weighed. The Chi Square test (χ2) with p=0.05 was used to analyze whether there is difference between the ratio of male and female. Gonadal maturity level was determined morphologically based on standard literature, while gonad somatic index was determined based on proportion of gonad weight and fish body weight. The length at first maturity was determined by using logistic curve. The results showed that the ratio between males and females was 1:1 in March and April while in February the ratio was 1≠1. Totally, gonad maturity level of female fish was dominated by GMS IV (52.1%) and the lowest was GMS I (5.9%), while for male fish the lowest GMS was GMS V (3.9%) and the highest was GMS IV (27.9%). The highest gonado somatic index value for male and female fish was owned by GMS IV in April, while the lowest occurred in February for GMS I. The length at first maturity of female and male fish was 20.1 cm. ABSTRAK Penelitian ini dilaksanakan di perairan negeri Tulehu, Pulau Ambon pada bulan Februari hingga April 2020 untuk mengkaji aspek reproduksi ikan lalosi (Pterocaesio tile) yang meliputi rasio kelamin, tingkat kematangan gonad, gonado somatik indeks dan ukuran pertama kali matang gonad. Sampel ikan lalosi dikumpulkan setiap minggu dari nelayan jaring insang yang beroperasi di perairan negeri Tulehu. Sampel ikan yang terkumpul dipisahkan menurut jenis kelaminnya, ditimbang beratnya dan diukur panjang totalnya. Semua sampel yang dikoleksi kemudian dibedah untuk diambil gonadnya, ditentukan tingkat kematangan gonadnya (TKG) dan ditimbang beratnya. Untuk menganalis apakah ada perbedaan yang nyata antara rasio ikan jantan dan betina digunakan uji Khi Kuadrat (χ2) dengan p=0,05. Tingkat kematangan gonad ditentukan secara morfologis berdasarkan standar literatur, sedangkan gonado somatik indeks ditentukan berdasarkan proporsi berat gonad dan berat tubuh ikan. Panjang pertama kali matang gonad ditentukan menggunakan kurva logistik. Hasil penelitian menunjukan bahwa rasio antara jantan dan betina adalah 1:1 pada bulan Maret dan April sedangkan pada bulan Februari rasionya 1≠1. Secara keseluruhan, tingkat kematangan gonad ikan betina didominasi oleh TKG IV (52,1%) dan terendah TKG I (5,9%), sedangkan untuk ikan jantan TKG terendah adalah TKG V (3,9%) dan tertinggi TKG IV (27,9%). Nilai gonado somatik indeks tertinggi untuk ikan jantan dan betina dimiliki oleh TKG IV pada bulan April sedangkan terendah terjadi pada bulan Februari untuk TKG I.
