Abstract

Asian moon scallops are one of the marine biological resource products that have the potential to be utilized optimally and in national and international trade and have high economic value. Kendal waters are one of the districts with significant Amusium pleuronectes resource potential to meet export needs in Indonesia, apart from the waters of Brebes, Tegal, Pemalang, Pekalongan, and Batang regencies. This research aims descriptively to explain the habitat characteristics of A. pleuronectes by connecting the condition of the relationship between body size and weight of A. pleuronectes and the parameters quality of the waters where the scallops are located, based on fishermen's fishing ground routes. A. pleuronectes was sampled using a fishing boat with a traditional arad net. The Global Positioning System (GPS) would be turned on when the arad net was finished being lifted, and the coordinates were recorded. The sampling stations were determined as 4 points, spread randomly (purposive sampling) along the route of fishermen catching A. pleuronectes. At the same time, water, sediment, and water parameter sampling was carried out. The samples were then taken to the laboratory for biometric measurements to determine the condition of the A. pleuronectes. Water samples were tested for chlorophyll-a and nitrate content, while sediment was tested for grain size and organic matter content. A Principal Component Analysis (PCA) analysis was conducted to determine the relationship between biometric parameters and water parameters. The results of this study showed that the scallops have a relationship between size and weight x<3, so they have negative allometry. These scallops have an average condition index of 51.12 and are in the medium category. In the preliminary survey, these scallops were dominated by the 4.1-5 cm size class. At stations 1-3, the size class 6.1-7 cm is dominated. A. pleuronectes were not found at station 4. These scallops showed a close relationship with salinity, depth, nitrate content, and silt substrate, with a higher content of coarse sand and clay as a substrate. There is little relation to organic matter, chlorophyll-a, temperature, dissolved oxygen, pH, gravel substrate, silt, and fine sand.

Abstract

The threadfin bream fish from the Nemipteridae family is a demersal species and an economically significant commercial fish. It is widely used for personal consumption and sold in markets. The capture of threadfin bream fish at the Oeba Fish Landing Site and Oesapa Fish Market has been increasing. Continuous high-intensity fishing will likely negatively impact the threadfin bream fish population, leading to stock depletion and reduced catch production. Research on threadfin bream fish in East Nusa Tenggara has yet to be reported, particularly in Kupang Bay and Rote Ndao waters. This study aims to investigate the fisheries biology of threadfin bream fish landed at the Oeba Fish Landing Site and Oesapa Fish Market. A total of 84 threadfin bream fish were sampled from both locations. The length-weight relationship of threadfin bream fish at these sites is negatively allometric with value b < 3, indicating that length growth is more dominant than weight gain. The gonad maturity stages of male and female threadfin bream fish range from GSM I-III. The size distribution of threadfin bream fish ranges from 173-295 mm at the Oeba Fish Landing Site and from 173-245 mm at the Oesapa Fish Market. Most of the threadfin bream found are still in the early stages of gonadal maturity, indicating that these fish are young and not yet ready to spawn. Implementing Sustainable fishing management practices is crucial, including setting catch quotas and minimum catch sizes and educating fishermen to ensure the sustainability of threadfin bream fish stocks.

Abstract

The Banggai cardinalfish (Pterapogon kauderni, Koumans, 1933) is an endemic coral reef fish species native to the waters of the Banggai Islands Regency. In 2007, the species was classified as endangered by the International Union for Conservation of Nature (IUCN), followed by its designation as a protected species with limited conservation status by Indonesia’s Ministry of Marine Affairs and Fisheries in 2018. Research on the Banggai cardinalfish has been conducted in its native habitat in the Banggai Islands as well as in introduced locations. One of these introduction sites is Gilimanuk Bay, Bali, which serves as a temporary holding area for ornamental corals before export and as a release site for Banggai cardinalfish that do not meet export standards, typically due to physical deformities. This study aims to analyze the horizontal and vertical distribution of the Banggai cardinalfish in Gilimanuk Bay, Bali, with the expectation that the findings may provide insights for government policy formulation in terms of conservation efforts. The research employed a descriptive exploratory method to provide a comprehensive description of the subject and to establish a data foundation for further research or decision-making. The results showed a total population of 2,253 fish. The highest horizontal population density was observed in the southwestern part of Gilimanuk Bay, with 2.87 individuals/m² across a 500 m² observation area distributed over 5 stations. Meanwhile, the highest vertical population density was found at a depth of 6–7 meters, with a density of 3.88 individuals/m² over a 100 m² observation area at one station.

Abstract

Riau Province needs to develop blood cockle (Anadara granosa) of seeding technology as an effort to reduce dependence on natural capture and dependence on seeds for cultivation from nature, which can threaten the sustainability of these biota resources. This research aims to determine the growth in length, weight and condition index of blood clams, and determine the gonad maturity level (TKG) of blood cockle. Length growth analysis (morphometric) in August 2019 with size classes small, medium to large and there was an increase in October 2019 in average size to medium to large. The results of the weight growth analysis (biometric) in August 2019 showed a value of b= 1.8903 and in October 2019 a value of b= 2.1382 indicating negative allometry. Where the increase in length is faster than the increase in weight. The gonads have developed well because they have reached a condition index > 20.00. The results of macroscopic analysis showed that blood cockle samples could be distinguished between male gamete cells and female gamete cells based on the color and shape of the gonads. Based on macroscopic and histological analysis, it shows that the level of gonad maturity is thought to have reached stage II (developing) in the developing stage. By knowing the gonad maturity level of the blood cockle, it is hoped that it can be implemented in supporting the construction of a blood cockle hatchery unit in Riau Province.

Abstract

 Shellfish are also known as by-products, namely production results that are not utilized or not consumed, where the value of this by-product can be increased/added through a process known as Reduce-Reuse and Recycle (3R). This research aims to determine the potential of shellfish as a source of calcium. Samples of clams (Paphia undulata), blood clams (Tegillarca granosa), and Asian Moon Scallop (Amusium pleuronectes) were obtained from Tambak Lorok Fish Auction Place, Semarang; then taken to the Marine Biology Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Diponegoro to have the shells, and air dry until dry after drying the shell. Calcium and mineral content were analyzed using the XRF method at the Integrated Laboratory, Universitas Diponegoro. The results of the study showed that the calcium (CaO) content of the three shellfish was the lowest in the clam (P. undulata) at 45.79%, then the Asian moon Scallop (A. pleuronectes) at 45.89%, and the highest in the blood cockle T. granosa namely 92.41%.  It can be concluded that the shells of clams, blood clams, and Asian Moon Scallops contain high levels of calcium and minerals, which have the potential to be used as an additional ingredient in concrete/paving blocks and fish feed.

Abstract

Rembang merupakan salah satu wilayah yang memiliki daerah pantai, karena letaknya yang berada di Utara Pulau Jawa. Perairan laut Kabupaten Rembang merupakan salah satu penghasil perikanan yang besar di Indonesia, salah satu jenisnya yaitu rajungan (Portunus pelagicus). Rajungan sangat rentan terhadap kontaminasi mikroplastik dikarenakan hidup di daerah pasang surut (intertidal) atau didasar perairan yang langsung bersentuhan dengan substrat. Tujuan penelitian ini mengkaji dan menganalisis kandungan mikroplastik pada daging rajungan (Portunus pelagicus), air laut, dan sedimen di perairan laut Desa Gegunung Wetan, Kabupaten Rembang, Jawa Tengah. Sampel rajungan, air laut, dan sedimen kemudian dilakukan analisis kandungan mikroplastik menggunakan 2 metode, yaitu metode analisis fisikal yang di lakukan Laboratorium Tropical Marine Biotechnologi, Fakultas Perikanan dan Ilmu Kelautan, Universitas Diponegoro, Semarang dan metode analisis FTIR (Fourier Transform Infrared) yang dilakukan di Laboratorium Terpadu Universitas Gajah Mada, Yogyakarta. Hasil Penelitian menunjukkan ditemukan adanya partikel mikroplastik pada sampel rajungan adalah 68 partikel mikroplastik, dengan hasil FTIR menunjukan mikroplastik berjenis Polystyrene, Polycarbonate, Latex, Nitrile, dan Poly (Methyl Methacrylate) (PMMA atau Acrylic). Kemudian total kandungan mikroplastik pada sampel air laut adalah 28 partikel mikroplastik, dengan hasil FTIR menunjukan mikroplastik berjenis Polystyrene dan Polycarbonate. Selanjutnya total kandungan mikroplastik pada sampel sedimen adalah 33 partikel mikroplastik, dengan hasil FTIR menunjukan mikroplastik berjenis Polypropylene, Polycarbonate, Polystyrene, Polyethylene Terephthalate (PETE), dan Nitrile.  Rembang is one of the areas that has a coastal area, because it is located in the north of the island of Java. The marine waters of Rembang Regency are one of the largest fishery producers in Indonesia, one of which is the blue swimming crab (Portunus pelagicus). Crayfish are very susceptible to microplastic contamination because they live in intertidal areas or on the bottom of waters that are in direct contact with the substrate. The purpose of this study was to examine and analyze the content of microplastics in blue swimming crab meat (Portunus pelagicus), seawater, and sediments in the sea waters of Gegunung Wetan Village, Rembang Regency, Central Java. The blue swimming crab, seawater, and sediment samples were then analyzed for microplastic content using 2 methods, namely the physical analysis method carried out by the Tropical Marine Biotechnology Laboratory, Faculty of Fisheries and Marine Sciences, Diponegoro University, Semarang and the FTIR (Fourier Transform Infrared) analysis method carried out at the Integrated Laboratory of Gadjah Mada University, Yogyakarta. The results showed that microplastic particles were found in the swimming crab, seawater, and sediment samples. The total microplastic content in the swimming crab sample was 68 microplastic particles, with the FTIR results showing the microplastics of the types Polystyrene, Polycarbonate, Latex, Nitrile, and Poly (Methyl Methacrylate) (PMMA or Acrylic). Then, the total microplastic content in the seawater sample was 28 microplastic particles, with the FTIR results showing polystyrene and polycarbonate microplastics. Furthermore, the total microplastic content in the sediment sample was 33 microplastic particles, with FTIR results showing microplastics of the types Polypropylene, Polycarbonate, Polystyrene, Polyethylene Terephthalate (PETE), and Nitrile.

Abstract

Chlorella vulgaris is a green microalga (Chlorophyta) known to produce chlorophyll pigment as its primary pigment. Chlorophyll is known for its health benefits because it helps heal wounds and prevent hemophilia and diabetes and asthma. Chlorophyll is one of the pigments targeted as a functional food source. One of the environmental parameters that can affect chlorophyll content is the presence of light. This study aims to determine the effect of differences in light intensity on the chlorophyll content of C. vulgaris. The method used in this research is experimental, conducted in the laboratory using a completely randomized design (RAL). ANOVA is the statistical analysis used to analyze the effect of light intensity on chlorophyll content in C. vulgaris. C. vulgaris was cultivated with three different light intensity treatments, namely 1500, 3000, and 4500 lux, with three repetitions each. The growth of C. vulgaris was observed for 8 x 24 hours and then harvested by centrifugation on the eighth day to obtain the wet biomass. Cultivation wet biomass was extracted using acetone PA solvent. The acetone extract of C. vulgaris was analyzed for its chlorophyll pigment content using a spectrophotometer at 645 and 663 nm absorbance. The highest content of chlorophyll-a, b, and chlorophyll produced at a light intensity of 1500 lux was 26.2, 48.5, and 74.7 µg/ml, respectively. According to the results of statistical analysis, it can be concluded that different light-intensity treatments did not show a significant effect (p>0.05) on the content of chlorophyll-a, b, and total chlorophyll in C. vulgaris.

Abstract

Seagrass is a higher plant that lives in shallow marine waters and plays an important role in tropical coastal ecosystems. Seagrass has the ability to reproduce in two ways, namely vegetatively and generatively. Enhalus acoroides is one of the species widely distributed in Indonesian tropical waters and can bear fruit throughout the year, but the survival rate of seedlings in nature tends to be low due to high environmental variability. Based on this, controlled generative sowing is an effective alternative in helping seedlings through the early stages of growth. This study aims to determine the effect of container and substrate variations, as well as their interaction, on the growth rate and survival rate of E. acoroides generative seedlings. The study results showed that substrate type had a significant effect on seedling growth rate (p = 0.004), whereas container type did not have a significant effect (p = 0.558). The interaction between container and substrate was also significant (p = 0.042). Seedlings grown in muddy sand exhibited a higher growth rate compared to those in sand. The survival rate across all treatment combinations was 100%, indicating that the different growing media were capable of optimally supporting the initial growth phase. These findings emphasize the importance of selecting an appropriate substrate to enhance the growth rate of seagrass seedlings.  Lamun merupakan tumbuhan tingkat tinggi yang hidup di perairan laut dangkal dan berperan penting dalam ekosistem pesisir tropis. Lamun memiliki kemampuan untuk bereproduksi melalui dua cara, yaitu vegetatif dan generatif. Lamun Enhalus acoroides merupakan salah satu spesies yang tersebar luas di perairan tropis Indonesia dan dapat berbuah sepanjang tahun, namun tingkat kelulushidupan bibit di alam cenderung rendah akibat tingginya variabilitas faktor lingkungan. Berdasarkan hal tersebut, penyemaian generatif secara terkontrol menjadi alternatif yang efektif dalam membantu bibit melewati fase awal pertumbuhan. Penelitian ini bertujuan untuk mengetahui pengaruh variasi wadah dan substrat, serta interaksi keduanya terhadap laju pertumbuhan dan kelulushidupan semaian generatif E. acoroides. Hasil penelitian menunjukkan bahwa jenis substrat berpengaruh signifikan terhadap laju pertumbuhan bibit (p = 0,004), namun jenis wadah tidak memberikan efek yang signifikan (p = 0,558). Interaksi wadah dengan substrat memberikan pengaruh yang berarti (p = 0,042). Substrat pasir berlumpur menghasilkan laju pertumbuhan yang lebih tinggi dibandingkan substrat pasir. Tingkat kelulushidupan seluruh kombinasi mendapat nilai sebesar 100%, mengindikasikan bahwa variasi media tanam tetap mampu mendukung fase awal pertumbuhan secara optimal. Temuan ini menegaskan bahwa pemilihan substrat yang tepat diperlukan untuk meningkatkan laju pertumbuhan bibit lamun.
