“…At four observation stations there were eight families of reef fish found in Mandangin Island waters (Figure 4). They were Caesionidae, Centriscidae, Chaetodontidae, Labridae, Mulidae, Nemipteridae, Pomacentridae, Scaridae, and Serranidae [21], which are often encountered in a coral reef ecosystem [22]. The Labridae and Pomacentridae families can be used for the assessment of coral conditions.…”

Blue swimming crab fishery activities very often do not put into account the environmental condition. Coral reef, as one of the blue swimming crab habitats, can be affected by these activities. This study aims to determine the effect of blue swimming crab fisheries on coral health in Mandangin Island, East Java, Indonesia. Data collection points are determined based on the results of interviews by participatory mapping. Water quality data includes visibility, temperature, salinity, pH, DO, current velocity. Collecting coral reef data were using Line Intercept Transect (LIT), while for reef fish Underwater Visual Census (UVC) were used. The coral health index was determined based on the relevance between benthic components and fish components. The average of Mandangin Island’s water quality is in accordance with the quality standards of the Indonesian Minister of Environment Decree No.51 of 2004. Hard coral cover and fish biomass are classified as low, but the value of resilience is high. The coral reef health index value on Mandangin Island is 3.

“…Alasan tertangkap dikarenakan ekosistem terumbu karang perairan Batangmata dalam kondisi baik dan layak dijadikan sebagai tempat hidup, mencari makan, dan tempat memijah. Utomo et al (2013) menambahkan bahwa kondisi karang yang semakin baik berbanding lurus dengan jumlah ikan karang yang hidup. Bandeng adalah jenis ikan yang tertangkap dalam jumlah paling sedikit.…”

Prinsip pengoperasian jaring insang adalah menghadang arah ruaya ikan. Keberhasilannya sangat tergantung pada ketepatan pemasangan jaring. Salah satu solusi untuk memperbaiki metode penangkapan adalah menambahkan alat pengumpul ikan berupa lampu atraktor yang dicelupkan ke dalam perairan. Jenis lampu atraktor yang cocok adalah lampu light emitting diode (LED). Tujuan yang ingin dicapai dari penelitian adalah menentukan komposisi jenis ikan hasil tangkapan dan membuktikan bahwa penggunaan lampu atraktor celup akan meningkatkan jumlah ikan hasil tangkapan. Jaring insang permukaan yang digunakan sebanyak dua unit. Salah satu unit dilengkapi dengan lampu atraktor celup. Hasil penelitian menunjukkan bahwa penggunaan lampu atraktor celup tidak mempengaruhi keragaman jenis ikan tangkapan. Kedua jaring insang menangkap 20 jenis ikan yang sama, yaitu lencam (Lethrinus obsoletus), tambak moncong (Lethrinus microdon), tambak belah (Lethrinus harak), ketambak (Lethrinus atkinsoni), jangki (Lethrinus ornatus), petek (Secutor indicius), cotek (Secutor insidiator), kakap ekor pelana (Lutjanus gibbus), kakap emas (Lutjanus johnii), belanak (Moolgarda perusii), gereh (Moolgarda seheli), baronang susu (Siganus canaliculatus), baronang kalung (Siganus virgatus), baronang angin (Siganus javus), baronang kunyit (Siganus puellus), baronang tompel (Siganus punctatus), kwee (Caranx tille), botana biru palsu (Acanthurus nigricauda), elak (Kyphosus vaigiensis), dan bandeng (Chanos chanos). Namun demikian, pemakaian lampu atraktor celup terbukti meningkatkan jumlah ikan hasil tangkapan jaring insang sebanyak 1.924 ekor, atau 74% lebih banyak dibandingkan dengan jaring insang tanpa lampu (1.108 ekor).

“…This ecosystem constitutes an essential biological resource in its complex biodiversity and is the basis for tropical fisheries and marine ecotourism industries [1]. On the other hand, tourism is a growing industry, and most of its development occurs in coastal areas and activities such as diving and snorkeling [1][2]. Despite their global importance, protection is currently inadequate, and consequently, key indicators of reef health, such as coral cover, are declining [3][4].…”

Sabira Island is an island close to Jakarta Province but still has good water conditions and a coral reef ecosystem with a high level of diversity. The condition of the coral reef ecosystem affects the community structure of the reef fish there. This study aims to determine the community structure of the reef fish on Sabira Island. The research was conducted in August 2019 on Sabira Island, Kepulauan Seribu Regency, DKI Jakarta Province. Observations of reef fish were carried out using the Underwater Visual Census method at four observation stations. There were 47 species of reef fish found on Sabira Island from 12 families. The total reef fish found were 1315 individuals, consisting of 79 indicator fish, 417 individual target fish, and 819 major fish. The highest diversity index value on Sabira Island was found at the South Station, with a diversity index value of 2.39. Based on the community structure index at the four observation stations, the reef fish community’s condition on Sabira Island is still good ranging from unstable to stable condition with moderate diversity and low dominance index values.
