The success of tiger shrimp farming in Oensuli Village's fishponds will be achieved if its location meets the criteria for tiger shrimp farming. Therefore it is important to conduct this research to find out the level of suitability of the actual land of tiger shrimp farms that are managed with high, and low production in Oensuli Village, Muna Regency. The method used is to compare the measurement results or the results of data analysis with the eligibility criteria/land quality for tiger shrimp farming. The results of this study illustrate the suitability of the actual land of tiger shrimp ponds with high and low production, as well as on land that has not been converted to ponds, it is obtained that the class category is quite appropriate (S2a1.2h), which means that there are water quality limiting factors such as temperature and brightness, and different tides ebbs are too high.
Changes on the mangrove ecosystem, directly and indirectly, affect the living organisms associated with it, including Molluscs. This study aimed to investigating Molluscs species in mangrove ecosystem of Kendari Bay. It is descriptive research containing facts and natures of mangrove Mollusc species. This study conducted from September to November 2020. Observing and collecting the Mollusc organisms were carried out in four mangrove ecosystems like Bruguiera, Bruguiera/Rhizophora, Rhizophora, and Avicenia. The method used in this research was an exploring technique by collecting and counting the found Mollusks. Indicators of observing the Mollusks included morphological characteristics and environmental parameters. Three important environmental parameters, like salinity, acidity (pH), and temperature, were measured during field works using hand refractometer, pH tester, and thermometer, respectively. This research indicates about 279 individuals of Mollusks found in all zones consisting of 17 species representing two classes, Gastropod (14 species) and Bivalves (3 species). During this research, the Gastropod Mollusks found Telescopium-telescopium, Terebralia palustris, T. sulcata, Cerithideopsilia cingulata, C. alata, Nerita squamulata, Cerithidea quadrata, C. obtusa, Latirus paetelianus, Cerithium kobelti, Chicoreus capucinus, Nassarius stolatus, N. niticusis, Siphonalia varicosus. For the three species of Bivalves are Polymesoda erosa, Anadora granosa, and Sacostrea cucullata. The both species T. sulcata and S. cucullata positively dominated all total found Gastropods and Bivalves namely 21.86% and 3.943%, respectively. The three water quality parameters measured at research stations are still on tolerance limits for the collected molluscs.
Fluktuasi pendapatan yang tidak stabil akan membuat nelayan merubah pola hidup agar dapat bertahan hidup. Salah faktor yang membuat pendapatan nelayan tidak stabil yaitu pandemi COVID-19. Pandemic ini membuat kepanikan publik di seluruh dunia saat ini. Ketidakpastian kondisi pandemi COVID- 19 saat ini sangat membuat nelayan jaring insang Kota Bengkulu frustasi untuk menjalani hidup di masa yang akan datang. Tujuan penelitian ini adalah untuk merumuskan prioritas strategi bertahan hidup nelayan jaring insang di Kota Bengkulu pasca COVID-19. Penelitian dilaksanakan pada Bulan April-Mei 2020 di Kota Bengkulu. Metode survei dipilih sebagai metode penelitian dan purpose sampling dipilih untuk teknik pengambilan data. Analisis yang digunakan yaitu strategi SWOT (Strenghts, Weakness, Opportunities, Threaths). Hasil penelitian menunjukan bahwa strategi bertahan hidup nelayan jaring insang di Kota Bengkulu pasca COVID-19 diprioritaskan pada strategi (ST) dengan memaksimalkan kelompok nelayan untuk lebih kreatif dalam melihat dinamika kondisi pandemi, bantuan pemerintah dan menjadikan keluarga dan agama sebagai motivasi agar mampu bertahan hidup pasca COVID-19. Bantuan tunai dari pemerintah sangat berguna untuk mengurangi beban hutang dan memberhentikan kegiatan illegal fishing seperti penggunaan alat tangkap trawl, sehingga saat musim ikan nelayan jaring insang mampu mengoptimalkan hasil tangkapannya.
