Abstrak. Penelitian ini bertujuan untuk mendeskripsikan komposisi spesies dan struktur komunitas ikan yang dapat bermigrasi melewati tangga ikan pada Bendung Perjaya, Sungai Komering, Sumatera Selatan. Penelitian dilaksanakan pada 2013 dengan tiga kali sampling yaitu pada Maret, Mei, dan Juli mengikuti musim. Pengambilan sampel ikan menggunakan alat tangkap yang tidak selektif, yaitu langgian (hand operated scoop net). Hasil penelitian didapatkan 5 famili yang meliputi 21 spesies, dengan jumlah spesies terbesar berasal dari famili Cyprinidae (15 spesies). Beberapa spesies yang dominan adalah Labeobarbus leptocheilus dan Crossocheilus sp. Kondisi musim berpengaruh terhadap struktur komunitas ikan, dimana keanekaragaman dan kemerataan cukup tinggi terjadi pada musim hujan (Maret) dan peralihan (Mei) tetapi rendah pada musim kemarau (Juli). Dominansi tinggi terjadi pada musim kemarau (Juli) tetapi rendah pada musim hujan (Maret) dan peralihan (Mei).Kata kunci: Tangga ikan; Bendung Perjaya; Migrasi ikan; Struktur komunitas ikan; Cyprinidae

Abstract. The decline in the quality of coral reef ecosystems is not only caused by human activities but also caused by competition in ecosystems, including competition for space and nutrients. Research on the comparison of coral reefs with macroalgae is one of the determinants of coral reef health which is the basis for the management of coral reefs with an ecosystem approach. The purpose of this study was to analyze the comparison of coral reef cover with macroalgae. The research method used is Line Intercept Transect (LIT), the research location is 13 stations divided into 3 locations, namely north, centre, and south from Ternate Island in North Maluku. The results showed that the condition of coral reefs ranged from 24 – 86.60%, based on the condition categories of 13 observation locations, the coral reefs of Ternate Island were in very good condition at 15.38%, good conditions at 46.16%, adequate conditions at 30.77%, and damaged conditions 7.69%, while the condition of macroalgae cover ranged from 0 - 30.60% in the area of coral reef ecosystems. The ratio of the of coral reefs to algae ranges from 0 to 1.117, based on the ratio value, it is classified as low, medium to high, spread in the coral reef ecosystem of Ternate Island. Coral reef management strategies on Ternate Island include a continuous monitoring program for coral reef ecosystems, education on coral reef ecosystems, creating a conscious community of waste, and limiting the capture and restoking of herbivorous fish in coral reef areas.Keywords: Coral reef, ecosystem approach management, macroalgae, Ternate Island

The aim of his studi was to evaluate the fish fauna in Danau Cala in dry season, transition season, and the tide season. The survey was conducted 3 times on July 2013, October 2013 and January 2014 as representative of dry, transition and tide seasons. The fish sampling was conducted by gillnets and fish traps. A total of 35 fish species were recorded during the study; 23 species in dry season, it was dominated by tembakang fish (Helostoma temminckii) from family Helosmatidae, Sepat siam fish(Trichogaster pectoralis) from Belontiidae family, and snakehead fish (Channa striata) of Channidae family. A total of 16 species were recorded on transitional seasons where baung fish (Hemibagrus nemurus) of the family Bagridae, and seluang fish (Rasbora sp) of the family Cyprinidae were predominant. In addition, 15 fish species were recorded on tide season which was dominated by baung fish (Hemibagrus nemurus) and tendon fish (Mystus sabanus) of family Bagridae

Abstract. As one of the coastal ecosystem, coral reef ecosystem is a magnificent marine ecosystem, where their species richness and composition play an important role for the ability of coral reef ecosystem to respond to the fishing activity and other stressors, where fishing has impacted the fish community, target or non-target reef fish species. The dynamic of reef fish resources, especially the target species, become one of the aspects that must be considered in the management and utilization of the fisheries resources in the coral reef ecosystem and their surrounding area. The purpose of the study was to analyze the dynamics of the target fish in the coral reef fishing activity at the coastal area of Ternate Island, from the growth, mortality and exploitation ratio aspect. The research was conduct from April to August 2018 in the coastal area of Ternate Island. The data sampling was growth parameters data through length and weight measurement. Total sample measure along the research time was 6245 sample (consist of seven family and 11 species). The result shows that the target fish have asymptotic length (L∞) range from 263.16–483.16 mm, with growth coefficient (K) ranging from 0.61–0.92 per year. The theoretic age at length 0 (t0) ranges from minus 0.0825–0.1669 year (equal to 30-61 day). The fishing mortality rate (F) is lower than the natural mortality rate (M), which resulting the exploitation rate (E) for the target fish mostly under 50%, which indicated that the utilization of the reef fishes in the coastal area of Ternate Island is still under-exploited.Keywords: Exploitation rate, Growth parameters, Length-weight relationship, Mortality rate, Stock assessment

This study aims to assess the distribution of Cherax quadricarinatus based on depth and evaluate its invasiveness using a risk assessment in Lake Laut Tawar, Central Aceh. The study was conducted at five stations representing various lake activities: Station 1 (One-One), Station 2 (Bewang), Station 3 (Gegarang), Station 4 (Mendale), and Station 5 (Dedalu). The methodology involved direct observation in the field followed by laboratory analysis. The results showed that 284 individuals were caught, consisting of 138 females and 146 males, with carapace lengths ranging from 20 to 76 mm. No consistent distribution of male and female carapace lengths was observed across all stations. The abundance of Cherax quadricarinatus in Lake Laut Tawar was classified as very abundant (20%) at One-One and Bewang stations, both at a depth of 5 meters. In conclusion, Cherax quadricarinatus significantly dominates the lake ecosystem, as indicated by its relative abundance at different depths across the study sites. This species also shows a high potential for invasion in freshwater lakes, highlighting the need for effective management strategies.Keywords:Cherax quadricarinatusInvasive spesiesLake Laut Tawar, Aceh
