Descriptive Method

One of the coastal ecosystems that has a high primary productivity, seagrass, makes it a places to find foods (feeding ground), spawn (spawning ground), and shelter for most fish. Whether the structure of fish communities on seagrass beds in the coastal waters of Doreri Bay based on day and night observation times is different from previous studies. This study aims to examine the structure of fish communities on seagrass beds in the coastal waters of Doreri Bay, between the time of observation and compared to previous studies. Data collection takes place during April-May 2019. The method used in this study is a descriptive method, using 1 and 1.5 inch gills net. The results of the study found that seagrass beds in Doreri Bay waters were more than in previous studies, which consisted of 10 species of seagrasses from 2 families (Hydrocharitaceae and Cymodoceaceae). The composition of fish is 56 species with a total of 91 individuals during the day and 189 individuals at night. Fish community structure in Doreri Bay waters has moderate diversity and uniformity while low dominance. Efforts should be made to protect seagrass ecosystems so that fish resources in the Doreri Bay region are maintained.

Seagrass ecosystem is providing feeding ground, nursery ground, spawning ground , habitat and shelter area. The threat of physical destruction such as the reclamation, pollution, sedimentation and tourism activities decreasing the diversity and the abundance of fishery commodities. The purpose of this study was to describe the condition of seagrass, determine the composition and abundance of seagrass fish in the three Southern coast of Bali and assess the association of fish-sea grass. Samples were taken from three coastal areas, Samuh, Shindu and Serangan coastal area. The results are in Samuhthere are 6 types of seagrass, in Shindu there are 7 types and in Serangan there are three types, whichdominates with Cymodocea rotundata and Syringodium isoetifolium. From the three coastal areas,we found 21 families of fish, where the family Pomacentridaehas the highest species abundance in Samuh, Apogon sp in Serangan and Terapon sp. found in Shindu. We can see the interaction between the seagrass ecosystems of coral reefs in the waters of South Bali and ecological role of seagrass from the family and species of fish.

Pengambilan sampel dilakukan menggunakan pukat pantai (Beach seine) dengan metode swept area pada bulan Mei-Juni 2016. Analisis data pada penelitian ini yaitu analisis data kelimpahan relatif individu ikan menggunakan formula KR=Ni/N x 100 selanjutnya analisis hubungan panjang dan berat menggunakan rumus W= aLb. Hasil pada penelitian ini ditemukan empat spesies ikan ekonomis penting yaitu Siganus gutatus, Siganus canaliculatus, Hemiramphus archipelagicus dan Terapon jarbua. Kelimpahan ikan ekonomis penting yaitu Siganus gutatus sebesar 33,60% dan yang paling rendah Terapon jarbua sebesar 21,24%. Sebaran panjang masing-masing spesies ikan yaitu Siganus guttatus 61-70 mm (46,6%). Siganus canaliculatus, sebaran panjang yang paling tinggi yaitu pada rentang 71-80 mm sebesar (33,1%). Hemiramphus archipelagicus, sebaran panjang yang paling tinggi yaitu pada rentang 131-150 mm sebesar (36,3%). Terapon jarbua, sebaran panjang yang paling tinggi yaitu pada rentang 91-100 mm sebesar (26,8%). Hubungan panjang dan berat ikan yang diperoleh menunjukkan bahwa pola pertumbuhan semua spesies adalah allometrik negatif. Dapat disimpulkan bahwa tingginya kelimpahan jenis ikan ekonomis penting yang berasosiasi dengan padang lamun yang berukuran juvenil sebagai indikator fungsi ekologi lamun sangat vital untuk ikan dapat survive.Kata Kunci : Padang Lamun, Distribusi dan Keragaman Ikan Ekonomis Penting.Abstract : This research aims to assess the stattus and population structure of economically important fish seagrass beds.

<p>The importance of seagrass meadows as a habitat for fishes, including several of economic importance, is widely acknowledged. The complexity of seagrass beds might offer a different condition of habitat for fishes. The physical nature of the seagrass canopy is thought to play a major role, potentially influencing available shelter, food, and protection from predators. Structural complexity of seagrass such as shoot and leaf density is also an important factor in determining ecological function of seagrass in the marine environment. The objective of the research is to assess the ecological function of different seagrass beds (in terms of spesies and density) in supporting fish community. The study found 28 species of fish originating from 14 families and Pomacentridae were dominantly found. Abundance of fish found to be higher in seagrass beds with high densities both composed by one species of seagrass (monospesific) or by more than one species of seagrass (multispesific), compared to the seagrass beds with low density and bare areas. Fish community diversity index was found higher in dense seagrass beds composed of many species of seagrass compared to the rare and consists of only one species of seagrass. The presence of epiphytes as nutrients for the fish that live in seagrass beds may contribute to the finding.</p><p>Keywords: Seagrass, fish, Barrang Lompo Island</p>

Seagrass provides many ecosystem services that are of beneficial to humans, including its role as a nursery ground for some commercial fishes. This ecosystem role depends on the structural complexity of seagrass beds. Yet few studies in Indonesia sought to associate seagrass with fish. The aim of this paper is to determine fish community response to different seagrass bed density. This study was carried out in the coastal waters of Tidung Kecil Island, Kepulauan Seribu. The fish observation was conducted using underwater visual census in stationary point count. The result showed that there were 21 species and S. canaliculatus was dominantly found. Fish abundance and fish community diversity index were found to be higher in seagrass beds with high densities compared to the seagrass beds with low density. The results of this study underline seagrass density can impact upon associated fish. This study provides the contribution of seagrass for coastal fisheries as a nursery ground. It is a way to promote the seagrass ecosystem to the society, therefore it can be considered into coastal policy.
