Abstract

Blue swimming crab (Portunus pelagicus) is one of the most economically valuable marine products in Indonesia. The crabs productivity was generally still dependent on the population in the wild. Danasari Village is one of the main crab producers in Pemalang Regency. The daily fishing crab activities by fisherman direct an impact on decreasing of the natural crabs resources. This study determined the crabs composition in the fishing ground where usually spotted by the Danasari crab fisherman. This research obtained the information of a composition of female and male crabs, carapace width distribution, growth characterized, and the egg-berried female number. This study conducted on May to July 2022. The result in this research was a male crabs were dominated than females. The carapace width was generally amount 92-112 mm, while the growth characteristic of blue swimming crabs was negative allometric. The female crab gonad maturity was dominated by 2nd level gonad maturity, while the egg-berried female crabs were found 21 crabs totaled from 14 spot fishing grounds. Based on the carapace width distribution, there are a lot of blue swimming crab with undersized in shallow-depth fishing sites, while the crab size mostly above 100 mm already found at each spot in this research. The highest egg-berried female percentage was found at spot 7th and 13rd, where the female crabs at 7th spot were bigger carapace than at 13rd spot areas. These results indicated that crab resources in Danasari Waters and surround area were indicated potentially overfished, proven with undersized berried-female crabs. The management efforts will conduct an environmentally friendly fishing gear, regarding the policy of ministry regulating as to keep crab resources sustainable. In addition, scheduling rules for fishing activities can also be tested to be applied.

Abstract

Mangrove degradation is one of the most common issues in the coastal areas of Java, which can cause ecological impacts and even disadvantage for local community. The mangrove forest degradation can be identified based on the vegetation analysis results, which could potentially contribute to the mangrove ecosystem management and rehabilitation programs in the coastal areas. Mangroves in Keboromo Village was the rehabilitation and cultivation area, but often get damaged by ocean waves. This study aims to determine the ecological and vegetation conditions of mangrove ecosystems consist of species composition, density, canopy cover, tree height, and environmental parameters were held in February 2023. The method used was direct observation using transect quadrants of 10x10 m2. The average mangrove density of all observation stations was 3.425 individuals/ha for the tree category, 575 individuals/ha for the sapling category, and 250 individuals/ha for the seedling category. The average percentage of canopy cover was 78.41%. The average height of mangrove trees at all stations is 4.15 m. The environmental parameters were still compatible with the water quality standard for biota and mangrove life. The mangrove forest degradation level based on standard criteria and guidelines for determining mangrove degradation is categorized as low, indicated by mangrove density >1500 individuals/ha and canopy cover >75%. Poor conditions were measured for sapling and seedling densities, which may be caused by environmental factors unsupportive for mangrove regeneration. Based on the results of mangrove vegetation analysis in Keboromo Village, it can state the mangrove ecosystem condition is good. However, management programs are needed to keep the mangroves sustainable.

Abstract

Rajungan betina memiliki peranan penting dalam keberlanjutan stok sumber daya rajungan di alam. Maraknya rajungan betina yang masih ditangkap oleh nelayan menjadi salah satu ancaman besar terhadap keberlanjutan sumber daya rajungan. Tujuan penelitian ini untuk mengetahui komposisi rajungan betina berdasarkan kelas lebar karapas, hubungan lebar karapas dan berat tubuh, komposisi tingkat kematangan gonad (TKG), nilai fekunditas dan persentase egg berried female (EBF) pada 20 titik area fishing ground yang dilaksanakan selama bulan Mei – Agustus 2022 di perairan Pemalang. Pengambilan sampel dan penentuan titik fishing ground dilakukan secara purposive sampling dengan menyesuaikan area penangkapan nelayan rajungan Desa Danasari, Pemalang. Distribusi ukuran lebar karapas rajungan menunjukkan modus kelas lebar karapas pada 101 – 110 mm, dimana kondisi tersebut tergolong kurang baik mengingat ukuran minimum rajungan yang boleh ditangkap adalah >100 mm. Hubungan lebar karapas dan berat tubuh menunjukkan pertumbuhan rajungan betina bersifat allometrik negatif, yang berarti pertambahan lebar karapas lebih cepat dibandingkan pertambahan berat tubuh. Komposisi TKG rajungan betina didominasi pada kondisi kematangan tingkat 2 (TKG 2) dengan persentase 78%. Nilai fekunditas rajungan betina bertelur dengan rata-rata pada kisaran 301.202±131.949 butir telur. Nilai EBF tertinggi ditemukan pada titik 12 dengan persentase 1,09% dengan rajungan betina bertelur sebanyak 7 ekor. Keberadaan rajungan betina di perairan menjadi salah satu faktor kunci keberlanjutan sumber daya rajungan, sehingga diharapkan dapat dijadikan acuan dalam penentuan area perlindungan dan kawasan potensial reproduksi rajungan di perairan Pemalang dan perairan lainnya. Female blue swimming crabs have an important role in the sustainability of crab populations of natural resources. The large number of female crabs that are still caught by fishermen is one of the major threats to the sustainability of crab resources. The purpose of this study was to determine the composition of female crab based on carapace width class, carapace width and body weight relationship, composition of gonad maturity level (TKG), fecundity value and percentage of egg berried female (EBF) at 20 spots of fishing ground area during May - August 2022 in Pemalang waters. Sampling and selection of fishing ground points were carried out by purposive sampling by adjusting the fishing area of crab fishermen in Danasari Village, Pemalang Regency. The distribution of carapace width size of crab showed the mode of carapace width class at 101 - 110 mm, where the condition is not quite good considering the minimum size of crab that can be caught is >100 mm. The relationship between carapace width and body weight shows that the growth of female crabs is negative allometric, which means that the increase in carapace width is faster than the increase in body weight. The TKG composition of female crabs is dominated by the condition of 2nd maturity level (TKG 2) with a percentage of 78%. The fecundity value of egg laying female crabs with an average in the range of 301,202±131,949 eggs. The highest EBF value was found at spot 12 with a percentage of 1,09%, with the number of egg berried female crabs are 7 individuals. The presence of female crabs in the waters is one of the key factors for the sustainability of crab resources, so it is expected to be used as a reference in determining protection and potential reproduction areas of blue swimming crabs in Pemalang waters and other waters.

Abstract

Ekosistem mangrove dapat dimanfaatkan oleh beberapa biota sebagai tempat untuk mencari makan, sebagai tempat memijah dan area asuhan. Kondisi ekosistem mangrove dapat mengalami penurunan salah satunya karena alih fungsi hutan mangrove. Hal ini akan berdampak buruk terhadap perekonomian nelayan, petambak dan masyarakat lainnya pada daerah tersebut. Penelitian ini perlu dilakukan dengan tujuan untuk menganalisis struktur komunitas mangrove yang ada di ekosistem hutan mangrove Kecamatan Tayu, Kabupaten Pati. Penelitian ini menggunakan metode survei dengan teknik purposive sampling untuk penentuan lokasinya. Terdapat 4 stasiun dan setiap stasiun terdiri dari 3 plot, masing-masing plot berukuran 10m x 10m untuk tingkat pohon dan 5 x 5 m untuk anakan. Pengolahan data struktur komunitas mangrove dilakukan dengan menggunakan perangkat lunak berupa Microsoft Excel. Terdapat dua jenis mangrove yang ditemukan pada penelitian ini yaitu Avicennia marina dan Avicennia alba. Kerapatan mangrove di lokasi penelitian tergolong sangat rapat. Berdasarkan nilai frekuensinya jenis Avicennia marina selalu ditemukan pada setiap plot pengamatan. Hasil indeks dominansi menyatakan bahwa pada Stasiun I hingga Stasiun IV terdapat jenis yang mendominasi dengan kisaran nilai sebesar 0,7 – 0,78. INP paling tinggi ada pada jenis Avicennia marina dengan nilai sebesar 260% dan tergolong tinggi. Hasil nilai indeks keanekaragaman menyatakan bahwa keanekaragaman mangrove pada lokasi penelitian ini tergolong rendah. Sedangkan nilai indeks keseragamannya termasuk dalam kategori sedang dan kurang. Secara umum parameter kualitas perairan (suhu, pH, salinitas, substrat dan kandungan nitrat, fosfat substrat) dinyatakan sesuai dan baik untuk kehidupan mangrove. Mangrove ecosystems can be used by some biota as a feeding, spawning and nursery ground. The condition of the mangrove ecosystem can experience a decline, one of which is due to the conversion of mangrove forests. This will adversely affect the economy of fishermen, farmers and other communities in the area. This study needs to be done with the aim to analyze the structure of mangrove communities in the mangrove forest ecosystem in Tayu District, Pati Regency. This research used a survey method with purposive sampling technique to determine the location. There were 4 stations and each station consisted of 3 plots, each plot measuring 10 x 10m for tree level and 5 x 5m for saplings. Mangrove community structure data processing was done by using software such as Microsoft Excel. There were two types of mangroves found in this study, namely Avicennia marina and Avicennia alba. The density of mangroves at the research site was classified as very tight. Based on the frequency value, the type of Avicennia marina was always found in each observation plot. The results of the dominance index states that at Station I to station IV there were types that dominate with a range of values of 0.7 to 0.78. The highest INP value was in the type of Avicennia marina with a value of 260% and was classified as high. The results of the diversity index value states that the diversity of mangroves at this research location is relatively low. While the value of the uniformity index was included in the category of medium and less. In general, water quality parameters (temperature, pH, salinity, substrate and nitrate phosphate content in the substrate) were stated to be suitable and good for mangrove life.

Abstract

Crab fishing activities using various fishing gears have the potential to catch other types of biota as known as bycatch. This type of bycatch is generally still used either for sale or for personal consumption, but some are re-released again. This research aims to determine the composition of the main catch and bycatch obtained by crab fishermen from Danasari Village, Pemalang. The research was carried out from July to August 2022. The data collection method was purposive sampling by going out to sea with fishermen to crab fishing grounds. The composition of the main catch and bycatch obtained at crab fishing locations consists of 1 type of main catch and 21 types of bycatch. The composition of the blue swimming crab is dominated by male crabs with a ratio of 1:0.7, with a mode of carapace width that is larger than female crabs, namely 107-115 mm. The proportion of bycatch obtained was only 25.73% from the total catch, with the useable bycatch amount more than the discarded bycatch. The ecological index shows that the value of species diversity and evenness is in the medium category with a value of 2.114 and 0.6944, while the dominance value is in the low category with a value of 0.1703. Useable bycatches that are commonly found are Orastoquilla oratoria, Scylla sp., and Babylonia spirata. The percentage of main catch is higher than bycatch, which indicates that fishing activities are still environmentally friendly, but the use of bycatch needs to be increased. It is hoped that data on the composition of bycatch types from Danasari Village fishermen can provide information on the potential of marine products other than crab, or could be said to be another alternative as a catch target to reduce exploitation of blue swimming crab resources. Aktivitas penangkapan perikanan rajungan dengan berbagai alat tangkap memiliki potensi terdapat jenis tangkapan biota lain atau disebut sebagai tangkapan samping. Jenis tangkapan samping (bycatch) umumnya tetap dimanfaatkan baik untuk dijual maupun sebagai konsumsi pribadi, namun ada juga yang dilepas kembali. Penelitian ini bertujuan untuk mengetahui komposisi tangkapan utama dan tangkapan samping yang didapatkan oleh nelayan rajungan dari Desa Danasari, Pemalang. Penelitian dilaksanakan selama bulan Juli sampai dengan Agustus 2022. Metode pengambilan data secara purposive sampling, yaitu ikut pergi melaut dengan nelayan ke lokasi penangkapan rajungan. Komposisi jenis tangkapan utama dan tangkapan samping yang didapatkan di lokasi penangkapan rajungan terdiri atas 1 jenis tangkapan utama dan 21 jenis tangkapan samping. Komposisi tangkapan utama rajungan didominasi oleh rajungan jantan dengan rasio 1:0,7, dengan modus ukuran lebar karapas yang lebih besar dibanding rajungan betina yaitu 107-115 mm. Proporsi tangkapan samping yang didapatkan hanya sebesar 25,73% dari total tangkapan keseluruhan, dengan jumlah tangkapan samping bernilai ekonomi lebih banyak dibandingan yang terbuang. Indeks ekologi menunjukkan nilai keanekaragaman dan keseragaman jenis termasuk kategori sedang dengan nilai 2,114 dan 0,6944, sedangkan nilai dominansi termasuk kategori rendah dengan nilai 0,1703. Tangkapan samping bernilai ekonomi (useable bycatch) yang umum ditemukan yaitu Orastoquilla oratoria, Scylla sp., dan Babylonia spirata. Persentase hasil tangkapan utama lebih tinggi dibandingkan tangkapan samping yang mengindikasikan aktivitas perikanan yang masih ramah lingkungan, namun pemanfaatan bycatch perlu untuk ditingkatkan. Data komposisi jenis tangkapan samping dari nelayan Desa Danasari diharapkan dapat menjadi informasi potensi hasil laut selain rajungan, atau bisa dikatakan sebagai alternatif lain sebagai target tangkapan untuk mengurangi eksploitasi sumberdaya rajungan. Crab fishing activities using various fishing gears have the potential to catch other types of biota as known as bycatch.
