Abstract

Penelitian ini bertujuan untuk mengetahui struktur komunitas plankton yang meliputi kelimpahan, keanekaragaman, keseragaman, dominansi, kesamaan habitat di Perairan Pantai Tanjung Kasuari. Hasil pengamatan menunjukkan bahwa fitoplankton yang ditemukan terdiri dari 3 kelas yaitu kelas Bacillariophyceae (27 genera), kelas Cyanophyceae (1 genus), dan kelas Dinophyceae (3 genera): zooplankton terdiri dari 7 kelompok yaitu Crustacea (8 genera), Protozoa (8 genera), Rotifera (1 genus), Urochordata (1 genus), larva Gastropoda (1 genus), larva Pelecynoda (1 genus), dan larva Polychaeta (1 genus). Komposisi jenis fitoplankton tertinggi pada setiap stasiun dari kelas Bacillariophyceae yang berkisar antara 81-91 % dan zooplankton dari kelompok Crustacea berkisar antara 31-55 % dari total jenis yang ada. Kelimpahan fitoplankton pada setiap stasiun pengamatan berkisar antara 527-6.991 ind/I dan kelimpahan zooplankton berkisar antara 8-152 ind/l. Jenis fitoplankton selalu ditemukan pada setiap stasiun pengamatan adalah Coscinodiscus, Navicula, Nitzschia, Rhizosolenia, Thalassiothrix, Peridinium. Sedangkan zooplankton selalu ditemukan adalah Calanus, Nauplius, dan Oithona. Nilai indeks keanekaragaman plankton berkisar antara 1.74-2,84 nits/individu, indeks keseragaman berkisar antara 0,53-0,80 dan indeks dominansi berkisar antara 0,08-0,27. A B S T R A C T The present study aimed to determine the structure of the phytoplankton community including abundance, diversity, uniformity, dominance, habitat similarity in Tanjung Kasuari Coastal Waters. The results showed that the phytoplankton found consisted of 3 classes, namely Bacillariophyceae class (27 genera), Cyanophyceae class (1 genus), and Dinophyceae class (3 genera): zooplankton consisted of 7 groups, namely Crustacea (8 genera), Protozoa (8 genera), Rotifera (1 genus), Urochordata (1 genus), Gastropod larvae (1 genus), Pelecynoda larvae (1 genus), and Polychaeta larvae (1 genus).

这项研究的目的是确定浮游生物群集的结构,这些浮游生物包括好望角食材海岸水域的丰富、多样性、均匀、支配和共同栖息地。发现的观察结果表明,浮游植物即由3班Bacillariophyceae(27已灭绝),Cyanophyceae年级(1),属Dinophyceae类(3已灭绝):浮游动物组成7组甲壳类动物(8已灭绝)、原生动物(8已灭绝),Rotifera属(属),Urochordata(1)属腹足类(1)幼虫,幼虫Pelecynoda(1)属,属Polychaeta幼虫(1)。鲍氏藻类的每一站中存在的浮游植物的最高组成范围从81到91不等,甲壳类动物的浮游动物的数量从31到55 %不等。每个观测站的浮游植物数量在527- 6991 ind/I和浮游动物数量在8-152 ind/l之间。每个观察站都发现了一种浮游植物,包括Coscinodiscus, Navicula, Nitzschia, Rhizosolenia, Thalassiothrix, Peridinium。而浮游动物总是被发现是Calanus, Nauplius和Oithona。浮游生物多样性指数的值范围在1.74- 2.84 nits/个体之间,均匀指数在0.53 - 0.80之间,占主导地位指数在0.08 - 0.27之间。目前的研究表明,包括植物浮游生物在内的植物群的结构、多样性、统一、自主权、相似的栖息地在喀山卡桑利海岸水域。phytoplankton发现consisted》The results那里那三个课堂,namely Bacillariophyceae课(27已灭绝),属Cyanophyceae课(1)和Dinophyceae课(3已灭绝):7的浮游动物consisted集团,namely甲壳类动物(8已灭绝),属原生动物(8已灭绝),Rotifera(1)、Urochordata(1)属Gastropod larvae(1),属Pelecynoda larvae(1),属和Polychaeta larvae(1)属。最重要的植物浮游生物组合来自蜗牛班,从81到91%不等,甲壳类动物从31到55%不等。对浮游生物的仔细观察从527到6,991磅,从8-152磅到l。在所有观察站发现的全浮游生物特征是Coscinodiscus, Navicula, Nitzschia, Rhizosolenia, Thalassiotrix, Peridinium。发现的浮游动物,卡兰努斯,纳普留斯和奥立修纳。浮游生物的多样性指数从1。74-2。84个个体中得到多样性指数从0。53-0。80得到自适应指数从0。
