Abstract. Sulardiono B, Hartoko A, Aini AN, Wulandari D, Budiharjo A. 2021. Genetic diversity of commercial sea cucumbers Stichopus (Echinoderm: Stichopodidae) based on DNA Barcoding in Karimunjawa, Indonesia. Biodiversitas 23: 922-927. DNA barcoding has proven a sufficient tool for species identification in varied groups of marine invertebrates, including crustaceans, mollusks, polychaetes, and echinoderms. The outdated system of morphological identification of the Stichopus spp. group is generally based on color patterns, causing confusion in identification. This study aimed to investigate genetic diversity, confirm the species identification, and examine phylogenetic relationships of the Stichopus genus (Echinoderm: Stichopodae) in the Karimunjawa Sea, by analyzing DNA sequence variation at cytochrome C oxidase subunit I (COI) in mitochondrial DNA and internal transcribed spacers (ITS). This genetic information is very helpful in inventorying and mapping commercial sea cucumber resources in Karimunjawa to support conservation efforts. Three types of sea cucumbers from the genus Stichopus were found, with different local names, namely Crengek gamete, Pace gamete, and Kuning gamete. The results of DNA extraction from the three samples showed that the DNA from soft bone tissue had a better level of purity and concentration than body tissue. The COI phylogenetic tree analysis showed that these samples with different local names were closely related to Stichopus monotuberculatus. Therefore, it is necessary to conserve the resources of the S. monotuberculatus in the management of Karimunjawa sea.

Teripang merupakan salah satu biota yang keberadaanya mulai terancam akibat tingginya aktifitas penangkapan. Tingginya aktifitas penangkapan tersebut menyebabkan jumlah populasi teripang terus menurun dengan tajam. Oleh karena itu, perlu diadakan penelitian untuk mengetahui bagaimana kondisi teripang tersebut. Penelitian dilakukan pada bulan November-Desember 2016 dengan 4 titik lokasi dimana titik 1 pada 5⁰87'05,38'' LS dan 110⁰36'33,25'' BT, titik 2 pada 5⁰88'45,90'' LS dan 110⁰35'81,89'' BT, titik 3 pada 5⁰88'18,65'' LS dan 110⁰34'82,57'' BT dan titik 4 pada 5⁰86'79,84'' LS dan 110⁰35'37,36'' BT. Penelitian ini bertujuan untuk mengetahui jenis dan kelimpahan teripang, mengetahui jumlah kandungan bahan organik sedimen perairan, sebaran spasial teripang tangkapan, dan hubungan bahan organik sedimen terhadap sebaran spasial teripang. Metode yang digunakan yaitu Random Purposive Sampling. Hasil penelitian menunjukan terdapat 4 spesies yang teridentifikasi yaitu Actinopyga echinites, Holothuria edulis, H. nobilis, dan Stichopus variegatus. Kelimpahan Teripang tertinggi pada titik 2 dengan 7 ind/m2. Sebaran spasial teripang tertinggi terdapat pada titik 2 yang memiliki kandungan bahan organik sedimen (5.7 %). Berdasarkan hasil uji regresi, bahan organik sedimen berhubungan dengan sebaran teripang. Hasil perhitungan uji regresi, angka koefisien determinasi (R2) adalah 0,603. Koefisien determinasi (R2) tersebut menunjukan bahwa kandungan bahan organik pada sedimen berpengaruh sebesar 60,3% terhadap sebaran Teripang di perairan tersebut. Hal tersebut juga menunjukan bahwa variabel lain memiliki pengaruh sebesar 39,7% terhadap sebaran Teripang. Uji korelasi menunjukkan kategori korelasi kuat dengan (r) adalah 0,778. Angka koefisien korelasi (r) = 0,778 dapat diartikan bahwa hubungan kedua variabel yang diuji adalah sangat kuat. Nilai F signifikan 4,33% artinya variabel bebas berpengaruh secara signifikan terhadap variabel terikat. Sea cucumber is one of the biota that its existence began to be threatened due to high catching activity. The high catching activity has caused the population of sea cucumbers to continue to decline sharply. Therefore, it is necessary to conduct research to find out how the condition of the sea cucumber. The study was conducted in November-December 2016 with 4 point locations where point 1 was at 5⁰87'05,38''LS and 110⁰36'33,25 '' BT, point 2 at 5⁰88'45,90 '' LS and 110⁰35'81, 89 '' BT, point 3 at 5⁰88'18,65 '' LS and 110⁰34'82,57 '' BT and point 4 at 5⁰86'79,84 '' LS and 110⁰35'37,36 '' BT. This study aims to determine the type and abundance of sea cucumbers, to know the amount of organic sedimentary water content, the spatial distribution of sea cucumbers, and the relationship of organic matter of sediment to the spatial distribution of sea cucumbers. The method used is Random Purposive Sampling. The results showed there were 4 species identified namely Actinopyga echinites, Holothuria edulis, H. nobilis, and Stichopus variegatus. Abundance of Sea Cucumber highest at point 2 with 7 ind/m2. The highest spatial distribution of sea cucumber is found at point 2 which has the content of organic sediment material (5.7%). Based on regression test result, organic sediment material is related to the distribution of sea cucumber. Result of calculation of regression test, coefficient of determination (R2) is 0,603. Coefficient of determination (R2) shows that the content of organic matter in sediment has an effect of 60.3% on the distribution of Sea Cucumber in these waters. It also shows that other variables have an effect of 39.7% on the distribution of Sea Cucumber. The correlation test indicates strong correlation category with (r) is 0.778. Correlation coefficient (r) = 0.778 can be interpreted that the relationship between the two variables tested is very strong. The value of F significant 4.33% means that independent variables significantly influence the dependent variable.

“…Sea cucumbers are one of the most potential export commodities in Indonesia (Choo 2008;Pangkey et al 2012). The increasing demand from the market has led to the rapid exploitation of sea cucumbers (Sulardiono 2016;Husain et al 2017). The exploitation efforts had a significant impact on the decline of the populations of sea cucumbers (Hasan 2019).…”

“…Karimunjawa National Park (KNP) is known to have various species of sea cucumbers (Sulardiono 2011), some of those are commercial species (Mustagfirin and Hartati 2017). Commercial sea cucumbers most commonly found in KNP are Holothuria edulis, Pearsonothuria graeffei, Bohadschia vitiensis, and Stichopus vastus (Sulardiono 2016). These sea cucumbers may be located mainly in complex reef habitats (Conand et al 2010;Sulardiono and Hendrarto 2014).…”

Abstract. Mustagfirin, Wijayanti DP, Subagiyo. 2021. Reproductive activity and morphometric assessment of three commercial species of sea cucumber (Echinodermata) from Karimunjawa National Park, Indonesia. Biodiversitas 22: 3333-3341. Sea cucumbers are benthic animals that have economic value and play an important role in the environment. Exploitation on large scale to fulfill high market demand, caused overexploitation. The number of sea cucumbers in Karimunjawa decreased as a result of limited management. There is no study conducted on the commercial sea cucumbers (Holothuria edulis, Pearsonothuria graeffei, and Bohadschia vitensis) in Nyamuk Island, Karimunjawa. The objectives of the research were to determine the morphometric assessment and the reproductive cycle of the three species. The morphometric assessment of weight showed that the weight of H. edulis ranges 247.3-2539g, P. graeffei 415.3-428.1g, and B. vitiensis 672.4-678.1g, respectively. The first maturity size of gutted body weight (GWB50) for H. edulis was 127.84g, P. graeffei 357.61g, and B. vitiensis 279.34g. The gonad somatic index (GSI) range 13.60-15.60% for H. edulis, 14.75-12.25% for P. graeffei and 10.83-14.57% for B. vitiensis. The result of gonad somatic index with a value above 10% means that it has entered the spawning phase. The above data indicated that the three commercial species spawned monthly, during new moon. It is likely that the spawning peak occurred when the temperature was increased. However, the pattern of reproductive activity in this study was limited at Nyamuk Island. Future studies are needed to observe whether there is a correlation between the increasing water temperature and the reproductive activity of the three sea cucumbers.
