Abstract

The catch results show that wire traps are an effective and selective fishing gear for Lutjanus johnii, with a total catch of 244.1 kg. The bycatch, consisting of 10 species, amounted to 208.1 kg, also caught using wire traps in the waters of Rigaih. This study aimed to identify the composition of the bycatch, the ratio between the target catches and the bycatch, and the size range of the dominant bycatch species caught during L. johnii fishing operations in Rigaih waters. The research was conducted in the waters of Rigaih during NovemberDecember 2024 using wire traps (dimensions: length x width x height = 120 x 100 x 75 cm). The results showed that the primary catch using wire traps was dominated by L. johnii, with a total of 135 individuals (48.7%) weighing 244.1 kg. The bycatch amounted to 208.1 kg (46.1%). The bycatch species included Caranx sexfasciatus with 42 individuals (15.2%) weighing 18.4 kg (4.1%), Lutjanus gibbus with 24 individuals (8.7%) weighing 31.9 kg (8.7%), and Epinephelus malabaricus with 24 individuals (8.7%) weighing 114.5 kg (25.3%). The dominant bycatch size classes caught in the wire traps included L. campechanus with a total length range of 1820 cm, L. campechanus with a total length range of 3045 cm, and Epinephelus malabaricus with a total length range of 4075 cm. The proportion of the target catch to bycatch by weight was 53.9% to 46.1%. This means that for every 1 kg of L. johnii caught, approximately 0.85 kg of bycatch was also captured.KeywordsLutjanus johniiwire trapAceh Jayasex ratiofish composition

Abstract

Sabang as the westernmost region of Indonesia and bordering the Indian Ocean and the Malacca Strait has fishery potential that must be maintained so that it is sustainable. Good management of grouper fish (Epinephelus sp.) resources is a solution so that fishery potential remains sustainable, one of which is the ecosystem approach. So far, many studies related to grouper management based on an ecosystem approach have been carried out in several regions in Indonesia, but none have focused on fisheries in Sabang. Therefore, this study aims to assess the status of grouper resource management, provide management recommendations and disseminate the results of the assessment of grouper resource management status in Sabang. This research was conducted from July to August 2022, located in Sabang, Aceh. Observation and direct interviews were conducted to collect the data and then analyzed by a multi-criteria analysis with composite index development. Based on the value of these indicators, it shows that the domain of grouper fish resources in Sabang caught using the hand line is good category with a green flag model and a composite value of 82. This means that the management of grouper fish resources in Sabang has not been running optimally. So, it is necessary to improve fisheries management in several aspects to support sustainable fisheries management.Keywords:GrouperEAFMSabangFisheriesSustainability

Abstract

The waters of Aceh are surrounded by three major water bodies: the Andaman Sea, the Indian Ocean, and the Malacca Strait. Differences in current patterns extend the distribution range and contribute to the species diversity. Fish from the Scaridae family are among the species that thrive in these environments. The family Scaridae (Rafinesque 1810), commonly known as parrotfish, inhabits tropical seas, including the Pacific, Indian, and Atlantic Oceans, and is often found in coral reef areas. Parrotfish play a crucial role in maintaining coral reef health as one of the herbivorous fish species. This study aims to analyze the morphometric variation of five parrotfish species harvested from the Northern waters of Aceh. Traditional morphometrics using 12 measurement characters were applied to 60 fish samples from five species of the Scaridae family (Chlorurus capistratoides, Chlorurus sordidus, Scarus ghobban, Scarus niger, and Scarus rubroviolaceus). The results showed that Scarus rubroviolaceus shares four similar characters with Scarus ghobban: ED, HL, CPL, and PFL; it also shares four characters with Scarus niger: ED, HL, CPL, and SNL. Chlorurus capistratoides shares three similar characteristics with Scarus niger: CPL, ED, and PFL. In addition, the results of the DFA analysis revealed that Scarus ghobban and Scarus niger exhibit the highest degree of similarity in morphometric traits, particularly in HL, SNL, DFBL, ED, and PFL. Furthermore, Scarus rubroviolaceus demonstrates a slight overlap with Chlorurus capistratoides, while Scarus niger shows a minor overlap with Scarus rubroviolaceus. This study provides morphological diversity of parrotfish species in the northern Aceh waters.Keywords:Aceh watersmorphometricsParrotfishMeasurement charactersDFA

Abstract

Edible film is a primary packaging in the form of a thin layer that covers food products, and it is usually made from hydrocolloids, lipids, and mixtures of both. Edible film from seaweed carrageenan (Kappaphycus alvarezii) extracts may serve as an alternative to plastic packaging, which is environmentally friendly and safe for consumption. This research aims to analyze the proximate composition ofK. alvareziisamples (lab-scale drying and conventional drying) and investigate its effects on physical characteristics (thickness values, solubility in water, water vapor transmission rate, elongation,and tensile strength) of the edible film. The research was carried out in several stages: sampling, sample preparation, carrageenan extraction, and edible filmmaking. The research was carried out using a completely randomized design with five treatments, namely the addition of 1%, 2%, 3%, 4%, and 5% (w/v) carrageenan extract. The research results showed significant differences in proximate values(water, ash, fat, fiber, and carbohydrates) between seaweed dried by farmers and seaweed dried in the laboratory. The addition of carrageenan extract significantly affected the edible film's thickness, water solubility, and tensile strength. The best characteristics were obtained at a concentration of 2% carrageenan extract, resulting in a thickness of 0.12 mm, solubility in water of 60.43%, water vapor transmission rate of 5.77 g/cm2/hour, elongation of 251.33%, and tensile strength of2.42 Mpa.The results of this research are essential for the development of packaging technology in the future.Keywords:edible filmKappaphycus alvareziicarrageenannutritionscharacteristics

Abstract

Research on microplastic (MP) accumulation in marine organisms' tissue have been widely conducted, as well as research on microplastic biodegradation by microbial organisms from the environment. Agelas conifera sponge is proven to accumulate MP in its tissue as well as having bacteria as symbiotic organism. This research aims to screen and study biodegradation activities of A. conifera symbiotic bacteria on MP polymers, also to identify the species of those bacteria isolates. Bacterial Isolation of A. conifera sponge tissue was using Zobell 2216E agar media. Screening and biodegradation assay of the bacteria isolates was conducted on Marine Salt Media agar that was added with 0,5 g of MP polymers, using Kroc-Boral method. Diameter of clear (bacterial growth) zone surrounding Kroc-Boral indicated the biodegradation activity of the bacterial isolates. Statistical analysis on the activity was using Two Way ANOVA. Results showed that there were 9 bacterial isolates of 53 that could degrade several MP polymers, with different activities (ANOVA, p value 0.05). High and low-density polymers (Linear- Low Density PolyEthylene/ LLDPE, Polyethylene/PE, and Polyvinyl Chloride/ PVC) were found to be degraded by all 9 isolates. Meanwhile, Polyethylen Taraphtalene (PET) and Polystyrene (PS) only degraded by 8 and 3 isolates, respectively. There are only 5 isolates that have high biodegradation index (1.5) on different polymers, which mostly on PET polymer. Isolate Ac8MP found to be the most bacteria that have degradation index on all polymers more than 1. This research proves that symbiotic bacteria could have a biodegradation mechanism on MP polymers that accumulates by sponge-host. However, further study needs to be done to understand the mechanisms and effectiveness of sponge-bacterial biodegradation activity.Keywords:Dumbo catfishLeukocytesErythrocytesGlucoseMusa AcuminataAeromonas hydrophila

Abstract

Halophila major is a new species with a wide distribution across various regions in Indonesia. The species was identified in 2020 through a combination of morphology and molecular approaches. Several studies have shown that it has a similar morphology to H. ovalis, which causes significant confusion during identification. Therefore, this study aims to describe the key identification and habitat of H. major and summarize seagrasses study opportunities based on the trend of published articles. A bibliometric analysis was used to summarize the habitat, morphometrics, molecular confirmation, and trend of seagrass topics in Indonesia. Based on the scientific articles, H. major has bigger morphometrics than H. ovalis. In addition, the number of paired and branching cross veins was reported to be an identification key of H. major. The species was also considered a deep ovalis found in 2-4 m depth. Genetically, the Internal Transcribed Spacer (ITS) gene marker was appropriate to showits phylogenetic tree. H. major was also classified into different clades with H. ovalis due to various factors. The results showed that genetics, tourism, and restoration were topics with the potential to be explored in the future. This study recommended collaborating in multi-institution to transfer knowledge, technologies, and project arrangements for seagrass exploration.Keywords:BibliometricHalophilaMarine angiospermaeMarin plantRediscoverySpecies

Abstract

The development of infrastructure could be one of a threat to habitat of horseshoe crabs. Regarding that, constructing of an international port at Kijing Beach in Mempawah could also become a menace to crabss habitat. Carcinoscorpius rotundicauda is known to be the most commonly found in Mempawah Mangrove Park (MMP) coastal area. This study aim is to analyze population structure and morphometry of Carsinoscorpius rotundicauda in MMP coastal area. Research was conducted on April-September 2022.Fishers collected horseshoe crab samples using trammel net. This study observed 14 characters and four ratios of morphometric, i.e. total length (TL), prosoma length (PL), opisthosoma length (OL), telson length (TSL), prosoma width (PW), carapace length (CL), compound eyes distance (CED), anal angle length (AAL), posterior angle distance (PAD), telson width (TW), median ridge length (MRL), anterior occeli length (AOL), process marginal length (PML), body weight (BW), PL/OL, PW/PL, CL/TL, and CL/PW. The number of individuals of horseshoe crabs found high on September. The sex ratio of males to females was 1.95:1. The highest frequency relative of prosoma width was found in the range around 1214 cm (adult size). The ratio of PW/PL of female crab was significantly bigger than male. This difference could be used for determining sex of this species crabs. The growth pattern of mangrove horseshoe crabs bot males and females were negative allometry.Keywords:AllometricCoastalHorseshoe crabMangroveMorphometric

Abstract

This study aims to analyze the role of women in promoting culinary tourism and to determine the production volume of smoked fish in Malalanda Village, Kulisusu District, North Buton Regency. The research was conducted from March to April 2024 using a purposive sampling method, considering the village's reputation for smoked fish production managed mostly by women. The population consisted of 19 female smoked fish processors, all of whom were selected as respondents through a census approach. Data were collected via interviews using questionnaires, direct observation, and secondary data from related institutions and literature. The results show that women are actively involved in all stages of smoked fish processing, including preparation, cleaning, sorting, smoking, cooling, and marketing. Production occurs up to 28 times per month, yielding a total of 14,334 pieces of smoked skipjack and tuna monthly. The highest individual output reached 952 fish per month, with an average of 796 fish per woman. These activities not only sustain culinary tourism but also contribute significantly to household income. The development of culinary tourism in the area highlights the vital economic role of women in local fisheries-based enterprises.Keywords:Culinary tourismIncomeSmoked fishWomen's roleWelfare

Abstract

This study aims to assess the distribution of Cherax quadricarinatus based on depth and evaluate its invasiveness using a risk assessment in Lake Laut Tawar, Central Aceh. The study was conducted at five stations representing various lake activities: Station 1 (One-One), Station 2 (Bewang), Station 3 (Gegarang), Station 4 (Mendale), and Station 5 (Dedalu). The methodology involved direct observation in the field followed by laboratory analysis. The results showed that 284 individuals were caught, consisting of 138 females and 146 males, with carapace lengths ranging from 20 to 76 mm. No consistent distribution of male and female carapace lengths was observed across all stations. The abundance of Cherax quadricarinatus in Lake Laut Tawar was classified as very abundant (20%) at One-One and Bewang stations, both at a depth of 5 meters. In conclusion, Cherax quadricarinatus significantly dominates the lake ecosystem, as indicated by its relative abundance at different depths across the study sites. This species also shows a high potential for invasion in freshwater lakes, highlighting the need for effective management strategies.Keywords:Cherax quadricarinatusInvasive spesiesLake Laut Tawar, Aceh
