International audience; Hatchery managers and maintaining genetic diversity and fitness population in endangered and threatened species in pond is a important and difficult thing to do. But is must to do for conservation biology. Fitness and structure population depends on effective breeding number (Ne) and population connectivity between each other. The second most important thing is gene flow and genetic drift. Ne is major role in the maintenance of genetic diversity as indicator for inbreeding depresion and genetic drift. We sampled 6 hatchery in Jakarta and Bekasi Indonesia region and used 12 polymorphic microsatellite loci to quantify population genetic structure. Result in this study are, each farm have different methode. The old farmers is bapakGusi and bapakHasan (+30 years). Ne in bapakHasan and bapakGusi hatcheryis 66,667 and F value is 0,00749 and loosing allele (P) is 0,26183. Compared with younger farmers bapakYahya (5 years) have Ne = 133,333, F = 0,00375 and P = 0,06855. Even though hatchery bapakHasan and bapakGusi have the same value Ne, F and P but the result in population structure they are different founder populations. Hatchery bapakHasan have unique structure and alleles composition compared with other hatchery.; Manajemen hatchery penting untuk mempertahankan keragaman genetik dan kebugaran populasi dari spesies langka dan terancam punah di pembudidaya dan hal ini sulit dilakukan, tetapi menjadi keharusan untuk biologi konservasi. Kebugaran dan struktur populasi tergantung pada efektif breeding number (Ne) dan konektivitas populasi antara satu sama lain serta aliran gen dan pergeseran genetik. Ne memiliki peran utama dalam pemeliharaan keanekaragaman genetik dan sebagai indikator terjadinya inbreeding dan pergeseran genetik. Terdapat 6 hatchery sampel di wilayah Jakarta dan Bekasi Indonesia dengan menggunakan 12 lokus mikrosatelit polimorfik untuk mengukur struktur genetik populasi. Hasil penelitian ini menunjukkan bahwa masing-masing hatchery memiliki metode yang berbeda. Pembudidaya paling lama adalah bapak Gusi dan bapak Hasan (30 tahun). Ne di hatchery bapak Hasan dan bapak Gusi adalah 66.667 dan nilai F adalah 0,00749 dan nilai kehilangan alel (P) adalah 0,26183. Dibandingkan dengan pembudidaya bapak Yahya (5 tahun) memiliki Ne = 133.333, F = 0,00375 dan P = 0,06855. Meskipun penetasan di hatchery bapak Hasan dan bapak Gusi memiliki nilai Ne, F dan P yang sama, tetapi hasil struktur populasinya adalah populasi pendiri yang berbeda. Hatcheri bapak Hasan memiliki struktur yang unik dan komposisi alel dibandingkan dengan pembenihan lainnya.

Les attaques d'helminthosporiose sur feuilles ont un effet néfaste sur cocotier et en particulier sur jeunes plants en pépinière. Des différences de comportement vis à vis des maladies sont souvent observées en fonction des cultivars; il a ainsi été mis en place une expérimentation visant à évaluer la résistance de plusieurs hybrides à l'égard de l'helminthosporiose. Cette expérimentation a eu lieu au jardin expérimental de Mapanget, Centre National de Recherche sur le cocotier, Indonésie, par observation directe des plants en pépinière de 25 hybrides différents. Les résultats montrent qu'il existe des différences du niveau de tolérance à cette maladie due à Helminthospodum sp., les croisements les plus sensibles étant NUS X GPY, NUS X GRL, NJB X GPY, NJB X GTA et NJB X GSA alors que les plus tolérants sont les hybrides de Nain (NBR, NUS, NJNj par le GOA.

Number: 1; International audience; Distribution and abundance of Pyrodinium bahamense cyst in the harmful algal blooms risk waters in Indonesia. Pyrodinium bahamenseas Harmful Algal Blooms (HABs) is one of the rising environmental problems in the coastal areas of Southeast Asia, particularly in Indonesia. Cyst bank formed after the blooms of P. bahamense is a potential source for the future blooming events. Therefore, an effort to describe the distribution and abundance of P. bahamense cyst banks in Indonesian coastal waters is necessary as a part of the mitigation strategy against the negative impacts of those toxic dinoflagellate blooms. This study was done as a desk study, which included a literature study, reanalysed of previous research data, and reanalysed of preserved samples or stored raw samples. Data and samples used in this study were collected and analysed from part of past researches in Lampung Bay, Jakarta Bay, Cirebon coastal waters, and Ambon Bay. This study also included an analysis to determine the P. Bahamense HABs risk level in the studied areas based on the cyst density and distribution data. Results showed a low density of P. bahamense cyst in Lampung Bay and Jakarta Bay, with cyst density \textless50 cysts.g-1 wet sediment. In contrast, the bottom sediments of Ambon Bay and Cirebon coastal waters contained high cyst density, which reached \textgreater1,000 cysts.g-1 wet sediment. Based on those data, the P. Bahamense HABs risk in Jakarta Bay and Lampung Bay would be generally much lower compared to Ambon Bay and Cirebon waters. The existence of cyst banks in those coastal waters may indicate a possibility of future blooms of P. bahamense.
