Aceh province has enormous fisheries potential, both freshwater and marine fisheries. one fishery biota which is featured prospect is prawns (Macrobrachium rosenbergii). Availability of the stock of prawns has been on the decline, and therefore this studied aims to determine the distribution of the existence of the brood stock prawns where located on the east coast of Aceh. This study used survey and analysis of water quality parameter. The results showed that on the east coast of Aceh where three districts that are in stock or distribution of prawns, Aceh Utaradistrict,Aceh Timurdistrictand Aceh Tamiang district. Aceh Utara district in the Tanah Pasir, Aceh Timur in the Peurelak and Aceh Tamiang in Seuruway. Distribution mains prawns in quality still showed a good result, but in terms of quantity was declining. The cause of the reduced number of prawns among other things because of the agricultural waste that causes pollution, because the region of Aceh are still many agricultural activities that still use pesticides. In addition due to fishing activities that use stun and tuba, very deadly existence of the stock of prawns are found in the waters of Aceh.

Environmental factors and geographical variations in an ecosystem are important steps in explaining the dynamics of marine communities, a study of seaweed that grows naturally on the west coast of Simeulue Island was conducted with the purpose of learning about the environmental characteristics, geographical variations, and environmental parameters that affect their distribution. The study was conducted in October 2021, and it included 5 observation stations with environmental factors measured in situ and geographic variation data using line transects along 50 m perpendicular to the shoreline and sample plots measuring 1 x 1 m every 10 m. Environmental factors that influence vegetation conditions and geographic variations of seaweed were analyzed using PCA. The study's findings revealed that conditions in the Indian Ocean with a high pH (average 07.72 ± 00.20) with moderate salinity and current velocity (average 32.47‰± 01.72 and 00.32 m/s ± 00.11, respectively) influenced the seaweed vegetation habitat. Then 21 seaweed species were identified, all of which have not been evaluated on the IUCN Red List, and their distribution is relatively rare, with a frequency of only 20%, and the seaweed zoning found at a depth of 0 - 150 cm at the lowest tide and a distance of up to 40 m inland from the edge. Furthermore, the distribution of seaweed on Simeulue Island's west coast is largely determined by DO conditions, salinity, and current velocity, whereas pH and temperature have less influence on seaweed distribution. Faktor lingkungan dan variasi geografik di suatu ekosistem merupakan langkah penting dalam menjelaskan dinamika komunitas laut, sehingga kajian rumput laut yang tumbuh alami di Pantai Barat Pulau Simeulue dilakukan dengan tujuan untuk mengetahui karakteristik lingkungan, variasi geografik dan parameter lingkungan yang mempengaruhi distribusinya.
