Abstract

This study aims to analyze seagrass community structure in North Salawati District, Raja Ampat. The scope of research is limited to identification of seagrass biodiversity, analyzing the overrune level of seagrass type covering the area, analyzing the densities types of seagrass important value index frequencies, water parameters and seagrass area. Research method was purposive sampling by using transects with dimensions of 1 x 1 meter with a total of seven stations along 100 meters of seagrass area. The acquired data was analyzed by using analysis of closure type, density type, frequency type, and important value index. Results of biodiversity identification showed that there are two families of seagrass, Eight species of seagrass covering the area. The overrune of seagrass covering the area in both stations is very high. The area of coverage in the both areas is above 60% (> 60%), which classified as "healthy". The density of the species in both stations is very high which classified as medium dense. Temperature, pH, DO, salinity and turbidity are in the optimum level which classified as "good". The area which overrune by Seagrass in the waters of northern Salawati District is amounted to 5.7 km2.

Abstract

Penelitian ini bertujuan untuk menganalisis jenis dan komposis lamun, penutupan lamun, kerapatan jenis lamun, dan sebaran lamun di Perairan Pulau Soop Kota Sorong-Papua Barat. Metode penelitian adalah eksploratif, yang mana pengambilan data keragaman jenis, komposisi dan kerapatan dilakukan menggunakan transek garis. Pengambilan data dengan Transek garis yang dilakukan pada setiap stasiun dengan cara posisi tegak lurus dengan garis pantai sepanjang setiap 10 m. Setiap transek garis dilakukan pencatatan data pada setiap 10 m tersebut, yang dimulai dari tepi pantai sampai tubir atau kedalaman tertentu. Data primer meliputi jenis lamun, tipe substrat, kerapatan, dan estimasi tutupan serta titik koordinat luasan dan titik pengambilan sampel. Kemudian data di analisis dan dibuatkan dalam bentuk peta dengan menggunakan software Arc-gis 10.6. Berdasarkan hasil penelitian di Perairan Pulau Soop terdapat 7 jenis lamun yaitu yaitu jenis Syringodium isoetifolium, Thalassia hemprici, Cymodocea serrulate, Thalassodendron ciliatum, Halophila ovalis, Enhalus acoroides dan Halodule uninervis. Penutupan lamun tertinggi di stasiun penelitian sebelah Utara perairan pulau Soop sebesar 51,58%, sedangkan penutupan lamun tertinggi di stasiun penelitian sebelah Selatan pulau Soop sebesar sebesar 38.35%. Luas sebaran lamun di sebelah utara dan selatan Perairan Pulau Soop sekitar 2.665.00 m2.

Abstract

This study aims to determine the effect of feeding trash and artificial feed on the growth and survival of juvenile duck grouper (Chromileptes altivelis). The research was conducted at the Ambon Marine Cultivation Center. The study consisted of 2 treatments, namely: Treatment A (trash feed) and Treatment B (artificial feed). The results showed that the growth rate and survival rate of juvenile duck grouper (Chromileptes altivelis) fed trash showed that the final average length was 10.56 cm and the final average weight was 11.52 grams, while the final average length was 11.52 grams. grouper duck fed artificial feed was 9.43 cm and the final average weight was 8.44 grams. The survival rate of grouper ducks given either artificial feed or trash feed resulted in a high survival rate of 100%.

Abstract

The coastal area of Pasangkayu Regency, has the potential of mangrove crab resources, which have not been utilized optimally. This study aims to determine the species composition, and biological aspects of the mangrove crab Scylla spp caught in the Fold trap in the mangrove ecosystem area in Pasangkayu Regency, West Sulawesi Province, Indonesia. The research was carried out from March to June 2020. The materials used consisted of the Global Positioning System (GPS), Camera; and digital scales and rulers. Types of data collected include primary and secondary data. Primary data were collected from surveys and field observations, secondary data were collected from various related agencies. Data analysis includes species composition and biological aspects. The results of the identification of mangrove crabs found 2 types of mud crabs, Scylla serrata and Scylla olivacea, which were more dominant than Scylla olivacea. The results of the analysis of the biological aspect showed that the mangrove crab species were Scylla serrata in the allometric minor category and Scylla olivacea in the isometric category. The size distribution of long class frequencies, types of Scylla serrata and Scylla olivacea. The sex ratio of Sylla serrata is in the balanced category and Sylla olivacea is not balanced, the number of females is less than males. The rate of exploitation of the two types of mangrove crab Scylla serrata and Scylla olivacea is still rational and sustainable, the E value <0.5% or the highest E value 0.5% is still considered sustainable. The conversion rate of mangrove ecosystems for various purposes needs to be reduced so that the mangrove crab habitat area is maintained.
