Abstract

The current research was conducted to investigate the effect of light on growth of soft coral Lobophytum strictum. This species was transplanted and reared in two different ponds, uncovered pond (with light penetration) and covered pond (no light penetration. A total of 16 coral fragments was placed on each pond. Both, the survival rate and the growth rate were significantly different on the effect of light (P<0.05). The soft coral on the uncovered pond was survive up to 12 weeks (100%), followed with increased length (from 5,95 to 10,04 cm) and width (from 5,27 to 6,84 cm) of the transplanted coral fragments. Conversely, the soft coral in the covered ponds showed survival rate of 62,5% (up to 8th week), with decreased length (from 8,25 to 5,25 cm) and width (from 9,14 to 4,86 cm) of each fragments during the period of study.

Abstract

This research was done on five sites (that are Southwestward, Marine Protected Area, Northeastward, and pier 1) on Pramuka Island, Seribu Islands, Jakarta. The data was taken by using Belt Transect Method which is unfold type for 60 meters parallels with shoreline, 2 meters in width of visibility, and 5 meters in depth. Kinds of coral that was collected are those from Family of Fungiidae. There are five genera from Family of Fungiidae found in Pramuka Island, that are Heliofungia, Herpolitha, Fungia, Ctenactis, and Sandalolitha. From 106 of total coral’s individu of Fungiidae in all sites of Pramuka Island, as much as 38.68% (41 individuals) of Fungiidae are healthy and as much as 61.32% (65 individuals) is got disease. Fungia is the most affected by coral disease. 19 of 61 individuals of Fungia (31.15%) are still healthy and 42 individuals (68.85%) affected by coral disease. On 24 individuals of Ctenactis that has found in all station, 70.83% of them affected by coral disease. From 13 individuals of Herpolitha, 38,46% of them affected by coral disease and 61,54% is healthy. From 6 individuals of Sandalolitha, as much as 50% recorded is affected by coral disease and 50% is healthy. Heliofungia is the only genera of Fungiidae that is not affected by coral disease in all observation stations on Pramuka Island. Coral disease that identified has attack the Fungiidae are Yellow Band Disease, bleaching (stripes, spots, patches dan full), Sediment Damage, combination between Sediment Damage and Yellow Band Disease, and Enlarge Structure. Yellow Band Disease are the one that most appear, which is represent 67,69% of the total coral disease in the Fungiidae with the value of disease abundance is 0,37 individu/m2.

Abstract

Acceleration of the process of recovery of damaged reefs require rehabilitation, management and supervision of well-planned and sustainable. One of the rehabilitation process is to create artificial reef. This study aims to look at the rate of attachment of sessile organisms on cement media called ?crypto?. A total of 270 cement media at each shelf. The size of cement media is 5x5x1 cm. The cement media were deployed at a depth of 6 meters and 10 meters. The rate of attachment of sessile organisms was compared between the upper and lower of the media side at each depth and between depths. Different organisms was observed colonized concrete media such as shells, sponges, worms, green algae, red algae, and brown algae. Percentage of coverage of sessile biota at a depth of 6 meters was significantly higher than 10 meters. Percentage of coverage of sponges at a depth of 6 meters and 10 meters, showed no significantly different (P = 0.0670). The other sessile biota, value of the test results showed significant differences between depths, such as the brown algae (P< 0.0001), red algae (P = 0.0003), and  green algae (P = 0.0022). The type succession occurs in this research was likely a primary succession.                                                        Keywords: sessile biota, biodiversity, rehabilitation, concrete block,                         colonization, succession

Abstract

Reliable and precise species identification is important to fisheries management and conservation. However, many rays and skates in Indonesia are currently being exploited and landed into traditional fish market without a proper identification. Therefore, this study was conducted to identify species of skates and stingrays that were landed and traded in three fish markets in Indonesia (Palabuhanratu, Muara Saban, and Lampung) using molecular techniques and to determine the conservation status of the identified species based on IUCN (International Union for Conservation of Nature and Natural Resources) as well as defined by CITES (Convention on International Trade in Endangered Species). The mitochondrial cytochrome oxidase I (COI) gene was amplified by polymerase chain reaction (PCR) using a pair of primer, fish-BCL and fish-BCH. Of 29 tissue samples collected from the study sites, a total of five species were successfully identified: Dipturus chilensis (4), Himantura walga (1), Neotrygon kuhlii (11), Taeniura lymma (9) and Rhinoptera javanica (4). The Neighbor Joining phylogeny of mitochondrial lineages, based on partial COI gene sequences, the ingroup haplotypes were clustered into five main clades representing each species. The identified stingrays were being listed as vulnerable (D. chilensis and R. javanica), near threatened (H. walga and T. lymma), and data deficient (N. kuhlii) by IUCN, with two species (D. chilensis and H. walga) population were indicated decreased. Unfortunately, all of identified species have not been evaluated by CITES regarding their trade status. As a consequences, a valuable effort should be placed to create a scientific network for monitoring programmes not only on a local scale, and to make pressure on governments for adopting molecular techniques as tools for controlling and avoiding misidentification.

Abstract

Genetik menjadi kunci konservasi karena berperan penting dalam  mempertahankan dan memulihkan populasi dari kerusakan. Kerusakan pada ekosistem terumbu karang dapat menjadi pemicu kepunahan organisme laut. Salah satu organisme yang tidak terhindar dari kerusakan tersebut ialah Sarcophyton trocheliophorum. Kerusakan tersebut dapat menyebabkan menurunnya keragaman genetik S. trocheliophorum. Tujuan dari penelitian ini adalah menganalisis keanekaragaman genetik dari S. trocheliophorum yang terdapat pada tiga populasi di Perairan Jawa, Sulawesi dan Nusa Tenggara serta mendeskripsikan implikasinya terhadap kawasan konservasi  di Indonesia. Penelitian ini menggunakan penanda genetik ND2 untuk menganalisis struktur populasi, konektivitas, dan keragaman genetik. Keragaman genetik S. trocheliophorum pada Perairan Jawa, Sulawesi, Nusa Tenggara masing-masing 0.600, 0.815, dan 0.972. Keragaman genetik pada populasi Perairan Jawa lebih kecil dibandingkan pada Populasi Perairan Sulawesi dan Nusa Tenggara. Hal ini dimungkinkan karena banyaknya aktivitas manusia pada pesisir utara Laut Jawa, sehingga berdampak pada menurunnya ukuran populasi S. trocheliophorum. Oleh karena itu perlu adanya perlindungan yang ketat pada populasi Jawa untuk menjaga kelestarian keanekaragaman hayati Indonesia.

Abstract

Penelitian yang dilakukan untuk mengetahui pengaruh cahaya terhadap pertumbuhan karang lunak Lobophytum strictum hasil transplantasi dilakukan dengan pemeliharaan karang lunak pada dua buah kolam, yaitu kolam terbuka (cahaya) dan kolam tertutup (tanpa cahaya). Pada masing-masing kolam ditempatkan 16 fragmen karang lunak yang sudah ditransplantasikan. Kelangsungan hidup dan pertumbuhan karang lunak berbeda signifikan antar perlakuan cahaya (P<0,05). Karang lunak yang dipelihara di kolam terbuka mampu bertahan hidup 100% (12 minggu), dengan disertai peningkatan panjang (5,95-10,04 cm)  dan lebar (5,27-6,84 cm) fragmen karang. Hal yang berbeda ditunjukkan karang lunak yang dipelihara di kolam tertutup, hanya mampu bertahan hidup hingga minggu ke-8 (62,5%). Hal ini disertai dengan penurunan panjang (8,25-5,25 cm) dan lebar (9,14-4,86 cm) fragmen setiap minggunya.
