Abstract

Baby crab consumption has become a growing trend in snack markets across Asia, with rising popularity in at least five countries. Cirebon, situated on the coast of West Java, is a region experiencing particularly high demand for baby crab commodities, notably the locally known "kroyo" crab. However, without adequate information on this species, its future stock sustainability may be compromised. Indonesian regulations governing high-value Crustacea commodities, outlined in Ministry of Marine Affairs and Fisheries Regulation Number 16 of 2022, include lobster (Panulirus spp.), mangrove crab (Scylla spp.), and blue swimming crab (Portunus spp.). This study employs both morphological and molecular analyses, utilizing DNA barcoding techniques. Male (AMJ) and female (AMB) crabs were collected in February 2023 from Gebang Waters, Cirebon, Indonesia. Morphological identification followed guidelines established by the Food and Agriculture Organization (FAO) for crabs, while molecular identification utilized the Cytochrome Oxidase I (COI) gene. Morphological features such as carapace characteristics, front-orbital border, and cheliped spine morphology categorize the specimens under the genus Charybdis. Specifically, the presence of two spines in the cheliped indicates classification as Charybdis anisodon, a conclusion supported by molecular analysis revealing a 98.9298.96% similarity with C. anisodon. Further analysis of the stock of this crab species is necessary to enhance awareness of its exploitation and inform sustainable management practices.Keywords:Baby crabDNA barcodingFisheries managementIdentificationMorphological

Abstract

Tambak budidaya udang banyak memproduksi limbah organik yang berasal dari sisa metabolisme dan sisa pakan dari kultivan budidaya. Keberadaan limbah organik yang melimpah dan tidak didampingi dengan manajemen kualitas air, akan mengakibatkan dampak buruk pada kultivan seperti kematian. Proses bioremediasi termasuk salah satu cara untuk membersihkan bahan pencemar pada lingkungan tambak yang dibantu oleh agen biologis yaitu bakteri. Bakteri amilolitik dapat digunakan sebagai agen bioremediator pada lingkungan karena menghasilkan enzim amilase. Amilase merupakan enzim yang mampu menghidrolisis pati menjadi senyawa yang lebih sederhana. Penelitian ini bertujuan untuk mengisolasi bakteri dari sedimen tambak udang vanname dan melakukan skrining enzim amilase menggunakan media Starch Casein Nitrat (SCN). Sedimen diambil pada 5 lokasi tambak pasca panen di Kabupaten Rembang. Sampel diisolasi menggunakan teknik pour plate dan purifikasi dengan teknik streak plate, sedangkan skrining enzim dilakukan dengan teknik dotting. Hasil penelitian yang didapatkan menunjukkan bahwa terdapat 20 isolat bakteri yang diisolasi dari sedimen tambak udang vanname dan 9 isolat bakteri menunjukkan aktivitas enzim amilase, diketahui dari zona bening yang dihasilkan pada isolat setelah ditambahkan iodine.

Abstract

The Banggai Cardinalfish, Pterapogon kauderni, has been introduced and spread in Kendari Bay, Southeast Sulawesi. The purpose of this study is to estimate the current fish density and distribution of microhabitats in Kendari Bay. Observations of fish populations used the belt transect method at 5 observation stations, with 4 replications per station. Overall fish density ranged from 82±10 individuals/100 m2 to 1,509±583 individuals/100 m2. The fish choose to associated with micorohabitats such as Diadema sp., (69.1%), fire coral from the genus Millepora (16.4%), Sea anemone (10.7%) and seagrass (3.8%). P. kauderni was observed coexisting with other fish species in microhabitats such as around seagrass roots and corals, without showing significant aggressive behavior. Considering its ecological adaptations, P. kauderni is potentially suitable for aquaculture systems that combine multiple species. With the right domestication approach, this species has great potential for development in a sustainable ornamental aquaculture industry.

Abstract

The development of crabs in Cirebon Regency is one of the important indicators in increasing fisheries production, the increase is based on the high market demand for crab commodities, especially kroyo crabs, causing an impact on the crab population. This research was carried out from February 2022 to March 2023 in 3 sub-districts, namely Suranenggala, Mundu and Gebang. This study aims to determine the stock of kroyo crabs which include carapace width and weight, growth, condition factors, mortality, and exploitation rate. The method used is direct observation of special fishermen catching kroyo crabs. The key crabs measured during the study amounted to 360 individuals with a carapace width range of male crabs of 27-44 mm and female crabs of 28-51 mm, with a frequency distribution of 8 class intervals from December 2022 to February 2023. Tools used to analyze stock conditions using the help of FISAT II and Microsoft Excel software. The first size results were caught in males (L50%=34,18mm) with more than half the asymptotic length (½L∞=23,75mm), while in females (L50%=41,08mm) greater than half the asymptotic length (½L∞=25,75mm). The carapace-weight width relationship of the male crab is W = 1,227L0,510 and the female crab W = 0,371L0,896. Conditions factors in male crabs (1,007) and females (1,008) have the same level of mon-decency. Growth equation of Von Bertalanffy male crab Lt=47,25[1- e(-0,79(t+0,179))] and female crabs Lt=51,45[1- e(-0,99(t+0,138))], So it can be stated that the growth of female crabs is faster than that of male crabs. In male crabs, the Total Mortality Rate (Z) was obtained at 2.99 per year, natural mortality (M) of 1.39 per year, and arrest mortality (F) of 1.60 per year. While in female crabs Z = 2.44 per year, M = 1.57 per year, F = 1.60 per year. The exploitation rate (E) of male crabs was obtained at 0.54 per year and females at 0.35 which means that the capture of Charybdis anisodon waters is still a tendency of underfishing. The pattern of adding new male crabs in Cirebon waters has two peaks, namely in April and August, with female crabs in July. Based on the results of this study, it can be concluded that the stock condition in Cirebon waters is still in the category of suitable for fishing for fishermen.

Abstract

The Awur Bay and Kartini Beach in Jepara, Central Java, are fishing areas with blue swimming crab as a main catch. This study aims to examine the species of blue swimming crabs captured in the Northern Waters of Jepara from different locations, analyze the molecular characteristics based on gender differences, obtain GenBank accession numbers as genetic conservation, and construct their phylogenetic tree. The research used a quantitative descriptive method. Samples were collected using purposive sampling from fishermen's catches and selected based on the difference in crab claws and carapace color, with a total of 4 samples. The samples were extracted using a DNA extraction kit and tested using Polymerase Chain Reaction (PCR) to visualize mitochondrial DNA (COI gene) and processed using MEGA 11. BLAST results showed that the similarity of the samples to Portunus pelagicus ranged from 97.02% to 99.42%. The different colors of claws and carapace did not affect the DNA sequence composition, hence indicating sexual dimorphisms. The DNA sequences from this study were deposited to GenBank with accession number LC836055.1-LC836058.1. Based on the phylogenetic tree construction, the clade of all samples shows a close relationship with the species Portunus pelagicus.

Abstract

Bacteria found in the digestive tract of shrimp mostly play a major role in nutrient absorption. One of the nutritional contents that is quite difficult for shrimp to absorb is fiber. Bacteria that can degrade fiber content are known as cellulolytic bacteria. This study aimed to determine the activity index of cellulolytic bacteria found in the digestive tract of shrimp. The research method includes sampling shrimp with three different categories based on average length and weight, divided into three categories such as large (22.2 g ± 87.3 cm), medium (17.1 g ± 36.7 cm), and small (13.4 g ± 18.8 cm) taken from the north coast waters of Pemalang and the south coast waters of Cilacap. Furthermore, bacterial isolation, morphological observation, calculation of bacterial abundance, and testing of cellulolytic activity were carried out. The results showed that 150 bacteria were successfully isolated from both locations at different sizes and a total of 68 bacterial isolates had cellulolytic activity. There were 22 potential isolates from each coastal water that had a great cellulolytic activity index, ranging from 1.4 to 7.0. Moreover, the most potential activities were performed by 8 bacterial isolates encoded with GM.1, GM.2, GM.3, GM.4, GM.5, GM.6, GM.7, and GM.8 with a range of cellulolytic index obtained ranging from 3.0-7.0. The high activity index of the cellulolytic bacteria obtained is a fairly promising potential as a probiotic candidate that plays a role in degrading fiber in food found in the digestive tract of shrimp so that it can accelerate its growth.

Abstract

Yellowfin tuna (Thunnus albacares) is the main target of capture fisheries in various tropical waters, including Indonesia, owing to its high economic value. Global market demand increases the rate of exploitation; therefore, the size of the catch is not considered. The increasing number of fishing units led to declines in tuna stocks, catches exceeding the limit, and a dominance of catch sizes smaller than the mature gonad size (Lc < Lm), resulting in a decrease in the biomass of spawning stocks. This study aimed to examine the profile of the yellowfin tuna population in the waters of East Nusa Tenggara (NTT) by analyzing its size structure, size-at-first-catch (Lc), mortality, recruitment patterns, production trends, and Catch Per Unit Effort (CPUE). Length and weight data were obtained from I-Fish (Indonesian Fisheries Information System) initiated by YMDPI. The analysis showed that the yellowfin tuna caught ranged in size from 78 to 173 cm and were dominated by the 94-125 cm size group (82.86%). The catch consisted of 99.99% adult fish and 0.01% juveniles. The Lc value ranged from 103.34–106.55 cm, fishing mortality (F=1.44) was higher than natural mortality (M = 0.71) and the exploitation rate (E) was 0.67, indicating overfishing. Recruitment occurred throughout the year, peaking in June. Production increases in April, June, and October. CPUE ranged from 0.45-0.80 tons/trip, most fish weighed 17-23 kg (38.32%) and fish weighed more than 45 kg <1%. Overall, this condition emphasizes the importance of sustainable management based on periodic data to maintain the sustainability of the tuna population and the fisheries industry. Tuna madidihang (Thunnus albacares) merupakan target utama perikanan tangkap di berbagai perairan tropis, termasuk Indonesia, karena bernilai ekonomi tinggi. Pemintaan pasar global meningkatkan laju eksploitasi, sehingga ukuran layak tangkap tidak diperhatikan. Penurunan stok tuna disebabkan oleh, meningkatnya jumlah unit penangkapan, volume tangkapan yang melebihi batas serta dominasi ukuran tangkapan lebih kecil dari ukuran matang gonad (Lc < Lm), menyebabkan biomassa stok memijah berkurang. Penelitian ini bertujuan untuk mengkaji profil populasi tuna madidihang di perairan Nusa Tenggara Timur (NTT) melalui analisis struktur ukuran, ukuran pertama kali tertangkap (Lc), mortalitas, pola rekrutmen, tren produksi dan Catch Per Unit Effort (CPUE). Data panjang dan berat diperoleh dari I-Fish (Indonesian Fisheries Information System) yang diinisiasi oleh YMDPI. Hasil analisis menunjukan, tuna madidihang yang tertangkap berukuran 78-173 cm, didominasi oleh kelompok ukuran 94-125 cm (82,86 %). Komposisi tangkapan terdiri dari 99,99% ikan dewasa dan 0,01% juvenil. Nilai Lc berisar dari 103,34–106,55 cm, mortalitas penangkapan (F=1,44) lebih tinggi dari mortalitas alami (M = 0,71) dan laju eksploitasi (E) sebesar 0,67, mengindikasikan terjadinya overfishing. Rekrutmen terjadi hampir sepanjang tahun, puncaknya pada bulan Juni. Produksi meningkat pada bulan April, Juni dan Oktober. CPUE berkisar antara 0,45-0,80 ton/trip, sebagian besar ikan berbobot 17-23 kg (38,32%) dan ikan berukuran lebih dari 45 kg < 1%. Secara keseluruhan kondisi ini menegaskan pentingnya pengelolaan berkelanjutan berbasis data periodik untuk menjaga kelestarian populasi dan industri perikanan tuna.
