Abstract

The tuna industry in Pulau Morotai holds significant economic potential. However, its utilization has primarily focused on tuna loin, while byproducts (waste) remain largely underutilized. This study aims to identify and analyze the economic potential of tuna byproducts in Pulau Morotai Regency. Data was collected from PT Harta Samudera during 2020-2022, encompassing tuna production, byproduct types, and volumes. The findings reveal that tuna waste accounts for 40.90% of the total tuna body weight. This waste comprises heads (15.45%), bones (10.45%), viscera (6.82%), and skin (3.64%). The estimated potential for processing tuna waste into fishmeal reaches 61,282.5 kg per year, with an economic value of Rp 1,225,650,000. Processing this waste can enhance the income of fishermen and fish processing industries, reduce environmental pollution, and support food security.

Abstract

The utilization of red snapper (Lutjanus malabaricus) in Arafura waters is already at its optimum point and is classified as over-exploited. Information on population parameters is needed so that management can be sustainable. This study aims to determine several aspects of population parameters (Lc, Lm, L, t0, K, Z, M, F, E). The data collection method uses red snapper sampling including sex, length, and total weight in the 2021-2022 fishing period at PPP Mayangan, Probolinggo. The total number of red snapper samples was 3,077 with the smallest length being 19 cm and the largest being 89 cm. The results showed a relationship between length and weight W = 4,106.10-2 L1,730 with a value of b = 1,730, meaning that b < 3 indicates a negative allometric growth pattern. Average length caught (Lc = 50 cmTL) < Average length at maturity (Lm = 52 cmTL). Based on the Von Bertalanffy model formula, the growth parameter values are obtained, namely asymptotic length (L∞) = 96 cm, growth coefficient (K) = 0.72 per year, and age at zero length (t0) = -0.789. The growth equation is Lt = 96[1-e-0,72 (t-(-0,789))]. The value of natural mortality (=M) is 1.04 per year and the value of mortality due to fishing (=F) is 1.39 per year so the total mortality (=Z) is 2.43 per year. The exploitation value/utilization rate (=E) is 0.57. This shows that the utilization level has experienced more capture and reached the optimum level.

Abstract

ABSTRACTThe main problem of shallow water fisheries is overfishing. To improve fishing capacity of overfished fisheries is potentially by implementing sea ranching. Sea ranching isa process of releasing juvenile to certain enclose marine water under process of put-grow-take system. Two crucial aspects for implementing sea-ranching system are space management and access control of fishermen to fisheries resources. Implementation of this concept needsstrong legitimated institution. This paper is aimed to analysis legitimation issues of sea ranching institution at Semak Daun shallow water in Seribu Island-Jakarta base on legitimacy theory both of legal-substantial and sociopolitic-cognitive perspective.Legitimacy is heavily perception matter, which is assumed that institution body is allowed to take expected, proper and right actions. The legitimated sea ranching institutionrequires a powerful authority to develop regulations and to take enforcement actions. For doing so, itmust meet political, regulative, scientific and morality reasons. For complementary that institution also needs to be supported by institutional pillars including regulative, normative and cognitive perspectives. Results of this analysis will be one of references to develop implementing institution of sea ranching at study site.Keywords: institutional legitimacy, overfishing, sea-ranching, shallow waterABSTRAKProblem utama perikanan perairan dangkal adalah tangkap lebih.Untuk meningkatkan produktivtas perikanan yang tangkap lebih dapat dilakukan dengan menerapkan sea ranching. Sea ranching adalah pelepasan juvenil yang dibudidayakan ke lingkungan laut tertutup dalam sistem lepas-tumbuh-panen. Dua aspek krusial penerapansea-ranching adalah tata ruang dan pengendalian akses nelayan pada sumberdaya. Implementasi sea ranchingmemerlukan kelembagaan yang mempunyai legitimasi kuat. Artikel ini bertujuan untuk menganalisis isu-isu legitimasi kelembagaan sea ranching pada perairan dangkal Semak Daun di Kepulaun Seribu-Jakarta dalam pandangan teoritis baik dalam perspektif legal-substansial dan sosial politik-koginitif. Legitimasi lebih merupakan persoalan persepsi, yang diasumsikan bahwa lembaga diijinkan untuk melakukan suatu tindakan yang yang diharapkan, tepat dan benar. Lembaga pengelola sea ranching yang legitimatif membutuhkan kewenangan yang kuat untuk menyusun peraturan dan melakukan tindakan penegakannya. Untuk itu, kelembagaan sea ranching harus memenuhi alasan politis, regulatif, ilmiah, dan moralitas. Untuk melengkapinya, kelembagaan tersebut juga membutuhkan dukungan pilar-pilar kelembagaan yang mencakup perspektif regulatif, normatif dan kognitif.Hasil analisis ini dapat menjadi salah satu rujukan untuk membangun kelembagaan implementasi sea ranching di lokasi studi.Kata kunci: legitimasi kelembagaan, perairan dangkal, sea-ranching, tangkap lebih

Abstract

Coral reefs, seagrass meadows and associated fish communities are essential coastal ecosystems that provide significant ecological and economic benefits. However, these habitats are increasingly threatened by anthropogenic activities and climate change. This study assessed coral cover, reef fish composition and abundance and seagrass distribution in the Tiaro Locally Managed Marine Area (LMMA), Solomon Islands, to evaluate ecosystem health and conservation effectiveness. Ecological surveys at eleven sites revealed variable coral cover, ranging from 26% to 52%, with bleaching and disease most prevalent at Kotatave (11%) and Kokomu (10%). Herbivorous fish, particularly Pomacentridae and Acanthuridae, dominated the fish assemblages, while predatory species were scarce, suggesting trophic imbalance. Seagrass coverage varied across sites, with Cymodocea rotundata being the most dominant species, especially at Leleona (72% coverage). The findings highlight the interdependence of coral, seagrass and fish communities and emphasize the need for integrated, community-based conservation strategies to enhance ecosystem resilience.

Abstract

Microplastic pollution, primarily driven by industrial, residential, and agricultural activities, is a growing concern in the middle section of the Citarum River, Indonesia. Microplastics research was conducted three times in the central Citarum watershed from February to April 2022. This study investigates the types, abundance, and polymer composition of microplastics found in the sediment and digestive tract of the Amazon sailfin catfish (Pterygoplichthys spp.). Four types of microplastic-pellets, films, fibers, and fragments were identified, with an average abundance of 602.22 ± 563.87 particles/kg in sediment and 90.6 ± 40.7 particles/individual in catfish.  The majority of particles were smaller than 0.3 mm. Identified polymers included Polyamide (PA), Polystyrene (PS), Polypropylene (PP), Cellulose Acetate (CA), Acrylonitrile Butadiene Styrene (ABS), Polyvinyl Chloride (PVC), Melamine, Ethylene Vinyl Acetate (EVA), Polyethylene (PE), Low-Density Polyethylene (LDPE), High-Density Polyethylene (HDPE), and Polyethylene Terephthalate (PET). Statistical analysis showed no significant difference in microplastic pollution among industrial, densely populated residential, and agricultural areas. These findings underscore the widespread distribution of microplastics in the Citarum River and highlight the need for comprehensive mitigation strategies.
