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.

Arumbai Market in Ambon City, Maluku Province, is a central hub for the trade of fishery products, particularly groupers. This study aims to describe the origin of grouper catches and to identify the species and sizes of groupers marketed at Arumbai Market. Groupers, which belong to the family Serranidae, are the primary predators in coral reef ecosystems. Fish identification was conducted based on Allen's guide and verified through FishBase. The study was conducted from December 2022 to February 2023 using a survey method through direct observation and interviews. Data were analyzed descriptively and presented in tables and graphs. The results showed that groupers at Arumbai Market come from four main locations: Manipa (34.47%), Liang (26.81%), Latuhalat (24.26%), and Pulau Tiga (14.47%). Eight dominant species of groupers in this market are Variola albimarginata (44.64%), Cephalopholis miniata (20.60%), Epinephelus fasciatus (12.45%), Epinephelus ongus (6.44%), Cephalopholis urodeta (6.44%), Cephalopholis sonnerati (5.58%), Epinephelus areolatus (3.00%), and Epinephelus fuscoguttatus (0.86%). Grouper sizes vary, with Cephalopholis miniata having a maximum size of 27.1 cm and a minimum size of 19.9 cm. This study provides essential information on the origin of catches, species dominance, and sizes of groupers marketed, which can serve as a basis for better fishery management. These findings indicate a significant potential for grouper trade in the region and highlight the importance of sustainable management to preserve the continuity of coral reef ecosystems and grouper populations.

This study examines the skipjack tuna fishing industry in North Seram District, Central Maluku Regency, which has been operated by local fishermen for many years. This fishery is categorized as a small-scale and concentrated effort in the Seram Sea, one of the small seas in the Indonesian archipelago, which is part of the Pacific Ocean, covering an area of approximately 12,000 square kilometers. The study employs the length-weight relationship analysis method and the von Bertalanffy growth model. The results indicate that the growth of skipjack tuna can be represented by the equation W = 0.0133L^3.0999 with a determination coefficient of 94%. The b coefficient value for the sampled skipjack tuna was 3.0999, indicating isometric growth (length and weight grow proportionally). The growth coefficient (K) of skipjack tuna was 0.17 per year, with an asymptotic length of 49.586 cm and a t0 value of -0.0748 years. The resulting von Bertalanffy equation is Lt = 49.58{1- e^-0.175(t+0.0748)}, which describes the growth pattern of skipjack tuna in the Seram Sea.
