“…This might be due to the high tolerance of Synedra sp. that enables the diatom (Bacillariophyta) to thrive in both freshwater (Harmoko and Krisnawati 2018) and marine water (Van de Vijver and Ector 2020). Rhizosolenia sp.…”

Abstract. Amin M, Fitria A, Mukti AT, Manguntungi AB, Amrullah S, Alim S, Martin MB. 2022. Evaluating the stomach content of Wild Scalloped Spiny Lobster (Panulirus homarus). Biodiversitas 23: 6397-6403. The high demand for spiny lobster seeds has placed intense pressure on the lobsters’ wild stock in Indonesia. To address this issue, a hatchery was developed to produce scalloped spiny lobster larvae. However, the dietary requirements after the yolk sac has been depleted have proven to be a significant challenge. Thus, the present study aimed to identify the potential live diet of scalloped spiny lobster larvae by identifying the stomach contents of lobster larvae captured in the wild. Fifteen scalloped spiny lobsters at the post-larval stage were collected from three fishing grounds: Gerupuk Bay (Lombok Island), Tawang Bay (East Java), and Prigi Bay (East Java), Indonesia. The stomach of each scalloped spiny lobster was dissected under a dissecting microscope and its contents were observed under a binocular microscope for plankton identification and abundance. The stomach contents of scalloped spiny lobster resulted in five identified plankton species collected from Prigi Bay [Tintinnopsis sp. (37.5%), Grammatophora sp. (25%), Synedra sp. (18.8%), Phormidium sp. (4.3%), and Rhizisolenia sp. (4.3%)]; six plankton species collected from Tawang Bay [Ochromonas sp. (32.3%), Synedra sp. (20.6%), Tintinnopsis sp. (14.7%), Uronema sp. (14.7%), Coscinodiscuss sp. (2.9%), and Planktoniella sp. (2.9%)]; and six plankton species collected from Gerupuk Bay [Synedra sp. (33.3%), Chlorococcum sp. (33.0%), Phormidium sp. (13.3%), Gymnidinium sp. (6.6%), unidentified Cirripedia (3.3%), Rhizosolenia sp. (3.0%)]. Of these plankton, Synedra sp. and Rhizolenia sp. were the most common representatives in the stomach of all lobster samples. Thus, assessing these two plankton genera is highly recommended for future studies.

“…Cyclotella meneghiniana is often found because it has no means of movement and can be found in shallow water with high nutrient levels (Tanaka, 2007;. Cyclotella meneghiniana one of the planktonic diatoms that can be found all over the world and is widely distributed in lakes, rivers, seas, and brackish water (Vuuren,2006;Harmoko, 2018). Cyclotella meneghiniana can live in extreme environments because there is excess metal content and can reflect high resistance to pollutants, especially metal pollution (El-Bestawy, 2000).…”

Diatom biodiversity is an increasing concern due to growing human impact, the study was carried out in one of the most important water storage reservoirs of Tembalang Region. The anthropogenic activity influence of diatom diversity in the UNDIP Reservoir. The reservoir of Universitas Diponegoro (UNDIP) Semarang was an area of 1.24 km2, with the deepest part of 15 meters, and able to accommodate water up to 13500 m3. This study aims to determine the relative abundance, diversity, evenness, dominance of diatoms and is expected to provide information about the condition of the waters in the Diponegoro University Reservoir, Semarang. Littoral benthic diatoms of five locations were sampled. Diatoms slides were prepared from scraping the rock surface with an area of 3x3 cm, dilute in 50 ml distilled water, and identification under the microscope with 1000 magnification. Analysis of the physical characteristics of the waters includes Temperature, pH, DO, TDS, Conductivity, and Turbidity. The diatom composition in UNDIP Reservoir consists of 72 species that belong to 20 genera. The Shannon-Wiener diversity index (H') ranges from 2-3. The dominance index (D) ranges from 0.05-0.17. The Evenness index (E) ranges from 0.54-0.90. Water quality parameters showed a fairly good value in the growth of diatoms. Dominated by periphytic taxa such as Cyclotella meneghiniana (15.72%), Brachysira microcephala (9.93%), and Achnanthidium minutissima (6.84%) which are widely distributed and live at temperatures of 20-30?C and pH >6.

“…Menurut Conradie (2008), Synedra memiliki sel pembungkus berlapis yang dapat dimanfaatkan sebagai pelindung tubuh. Sel Pinnularia dapat berbentuk linear, lanset dan bahkan berbentuk elips, dan Pinnularia dapat hidup pada sedimen dan substrat yang bercampur dengan gumpalan lumut (Harmoko, 2018). Selain itu, Synedra dan Pinnularia juga dapat bertahan pada kondisi perairan yang rendah nutrisi.…”

Mikroalga epifit merupakan organisme yang dapat hidup menempel pada substrat seperti makroalga. Epifit memiliki peran penting dalam meningkatkan produktivitas primer dan bioindikator perairan. Tujuan dari penelitian ini untuk mengetahui struktur komunitas mikroalga epifit berasosiasi pada Sargassum sp. di perairan Desa Sepempang, Kabupaten Natuna. Penelitian dilaksanakan pada bulan januari juni 2019. Pengambilan sampel mikroalga epifit dilaksanakan secara in situ. Penelitian dilakukan dengan metode survey dan penentuan stasiun pengambilan sampel secara purposive sampling. Lokasi pengambilan sampel makroalga terdiri dari 4 stasiun dengan rona lingkungan yang berbeda. Hasil identifikasi mikroalga epifit terdiri dari 8 kelas, 36 ordo, 50 famili dan 65 genus. Kelas bacillariophyceae (diatom) ditemukan dominan dengan persentase kelimpahan (72.67%), dimana kelimpahan diatom pennate (81.69%) dan diatom sentris (18.31%). Genus yang dominan ditemukan adalah Navicula, Nitzschia, Synedra, Cocconeis dan Pinnularia. Nilai indeks keanekaragaman (H) berkisar 3.04-3.18, indeks keseragaman (E) berkisar 0.77-0.83, indeks dominasi (C) berkisar 0.06-0.07, dan nilai indeks Similaritas Sorensen (ISS) berkisar 75.55-87.80%.
