<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.

 Environmental characteristics can influence the distribu-tion of animal communities including fish in aquatic habitats such as a river. The study of fish communities in Cisadea River aimed to learn the relation between the fish community structure and the environmental characteristics of the river itself. This research was conducted in Cisadea River, Cianjur Regency, West Java, Indone-sia during dry season from July 2012 until February 2013. Samples of fish were caught using active fishing gear (Electrofishing Gear, spreading nets, scoop, lift net) and passive fishing gear (trap). The results showed that the quality of the physical chemistry of Cisadea waters was still in the normal range that could support fish life. The fish community in Cisadea River consisted of 11 orders, 26 families, 35 genera and 48 species. During the study, Rhyacichthys aspro (19,85%) and Glyptothorax plathypogon (20,15%) were the domi-nant species caught. The diversity index value (H’) was 2.87 (mid-dle category) with the dominance value of 0.09 (low category) and evenness value of 0.74 (high category). Moreover, community simi-larities according to the presence of species made the LC1 and LC2 locations in one group while the LC3 locations in a separate group.

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.

The aims of the study were to determine the composition of species and structure of fish communities in seagrass beds ecosystems. Fish were collected every spring and neap tide for three month periode with a swept area method using beach seine. Fishes were collected as many as 6444 individuals representing 68 species from 29 families. Siganus canaliculatus was contributed up to 62.91% of the total individual fish found.The fish community structure was varied between spring and neap tide. Index of dominance was in low category, diversity in medium, and evenness in unstable conditions. Moreover, the results indicated that seagrass ecosystems in Tanjung Tiram (TAD) have an important role as spawning, nursery ground, and feeding ground. Therefore, management and conservation efforts are urgently needed to maintain the ecological role of seagrass ecosystems for the sustainability of the fish resources.</p><p>Keywords: Seagrass beds, fish community, tanjung tiram, inner Ambon Bay</p>

Structure Patterns

Understanding the spatial distribution of fish species and fish trophic guilds in reef environments may help improve our knowledge about ecological relationships and therefore favour sound strategies for sampling, coastal management and conservation policy. To verify if small-scale changes are important in forming the fish community structure at a tropical rocky coastal island, we assessed the depth, structural complexity and wave exposure gradients. The community structure changed along all gradients analysed. The trophic guilds found on the sheltered, low and intermediate exposure zones, in the deepest areas and in areas of highest structural complexity showed significant differences when compared with the general assemblage. Rocky reefs, even of narrow (transversal) extension, can show great changes in fish community structure at so small a scale that these changes are generally overlooked. The relationships evidenced between community and environment provide strong support for the importance of considering a wide array of such distinct environmental conditions when determining the structure patterns of the community.
