“…Krebs (2014) further explained that species diversity is used to measure the stability of a community which is the ability of a community to keep itself stable despite disturbances to its components. Maturbongs et al (2018) argued that the area or mud substrate is a habitat for various nekton, which indicates the area has abundant food sources. The existence of habitat variations (substrate), such as physical conditions and the surrounding environment, affects the diversity of fish species.…”

“…The dominance of species in water often occurs due to several things, including competition for natural food by certain species accompanied by changes in environmental quality and an imbalance between predators and prey, resulting in competition between species. Maturbongs et al (2018) explained that dominance occurs because of the result of the competition process for evicting one individual against another. Okyere (2018) stated that at low tide, the estuary area is dominated by brackish fish species, one of which is from the Gobiidae family.…”

Abstract. Baderan DWK, Aydalina RV, Hamidun MS. 2023. Morphological characteristics and biodiversity of mudskipper fish (Periophthalmus: Gobiidae) in mangrove ecosystem of coastal Bay of Tomini, Gorontalo Province, Indonesia. Biodiversitas 24: 498-507. The southern sea area of Gorontalo Province is part of Tomini bay, the biggest bay in Indonesia. This area has a unique biodiversity and is Sulawesi endemic. The mangrove forest in the coastal bay of Tomini Boalemo is one of the habitats for flora and fauna, a place for spawning, nurturing, and food hunting for fish. The mudskipper is a fish that lives in the mangrove area. This study aims to reveal the morphological characteristics and biodiversity of mudskipper (Periophthalmus: Gobiidae) in the ecosystem of Tomini Boalemo coastal bay of Gorontalo Province. This study employed a quantitative descriptive that also implemented purposive sampling as the sampling method in three ecosystem stations of Tomini Boalemo coastal bay (Dulupi, Bajo, and East Pentadu mangrove). The mudskippers were collected manually when the water was receding using a fish net. The sample which had been collected were then identified based on 22 morphological, 24 morphometric, and seven meristic characteristics. The identification results were then compared with the identification key. The mudskippers' species were then analyzed to determine the species' biodiversity (diversity, evenness, species richness, and dominance indexes). The research result revealed five species from Periophthalmus Genus: Periophthalmus argentilineatus, Periophthalmus kalolo, Periophthalmus malaccensis, Periophthalmus minutus, Periophthalmus variabilis, with total individuals 561. The score of H?: 1.09 showed that the diversity of mudskipper fish was categorized as medium. The evenness index was 0.99 obtained from 3 observation stations, while the lowest dominance index was on station II with a score of 0.34, and the score of R1 in each station was respectively (0.19); (0.36); and (0.2). The results of this study could be used as a database for the sustainable management of Tomini Bay to tackle the threats of species extinction through aquatic life protection and preservation to arrange the natural balance and support the availability of the coastal resource for future generations.

“…Genus Boleopthalmus jumlah individu paling banyak karena jenis ini menghabiskan waktunya berendam di lumpur dan senang melompat-lompat pada saat melakukan aktifitas, jadi penangkapan lebih banyak, dan memiliki sarang yang berada di daerah pasang surut mundah untuk mengambil dalam sarangnya, didukung dengan pernyataan (Maturbongs, Elviana, Sunarni, & deFretes, 2018) bahwa genus Boleopthalmus dalam sarang yang berbentuk saluran-saluran didalam substrat dengan kedalaman antara 40-100 cm sedangkan hasil tangkapan Periopthalmodon schlosseri paling sedikit karena pada lokasi penelitian tidak terlihat jenis Periopthalmodon schlosseri berada pada permukaan lumpur, karena termasuk ikan yang endemis sehingga tidak dapat ditemui disembarang tempat (Maturbongs et al, 2018).…”

“…Dari data parameter fisik kimia di kawasan mangrove pada Boleopthalmus pectinirostris dan Periopthalmodon schlosseri memiliki pH tanah rata-rata 6-6,5, pH air 7,1, kelembapan 8, dan suhu air rata-rata 28,1 dengan subtrat tanah berlumpur, namun dari kedua spesies memiliki perbedaan dimana Boleopthalmus pectinirostris jumlah individu paling banyak karena jenis ini menghabiskan waktunya berendam di lumpur dan senang melompatlompat pada saat melakukan aktifitas, jadi penangkapan lebih banyak, dan memiliki sarang yang berada di daerah pasang surut mundah untuk mengambil dalam sarangnya, didukung dengan pernyataan (Sunarni & Maturbongs, 2017) bahwa ikan gelodok genus Boleopthalmus dalam sarang yang berbentuk saluran-saluran didalam substrat dengan kedalaman antara 40-100cm. Namun hasil tangkapan Periopthalmodon schlosseri paling sedikit karena pada lokasi penelitian tidak terlihat jenis Periopthalmodon schlosseri berada pada permukaan lumpur, termasuk ikan yang endemis sehingga tidak dapat ditemui disembarang tempat (Maturbongs et al, 2018).…”

Periopthalmus sp. merupakan salah satu jenis biota yang menyukai lingkungan yang bersubrat lumpur dan hutan mangrove. Penelitian ini bertujuan untuk mengetahui keanekaragaman jenis dan kelimpahan Periophalmus sp. di kawasan mangrove pantai Kertomulyo Pati. Pengambilan sampel Periopthalmus sp. dilakukan pada saat pagi hari dimana air laut sedang surut, mengambil ikan secara manual yaitu menggunakan tanggan dan alat pembantu lainya seperti jarring dan serok ikan. Hasil penelitian terdapat jumlah ikan sebanyak 386 individu, terdapat 2 genus dan 4 spesies, kelimpahan Periothalmus sp. yang memiliki kategori tinggi adalah Baleopthalmus pectinirostris 139 individu, sedangkan kategori rendah adalah Periopthalmodon schloresseri 14 individu. Indeks keanekaragaman yang diperoleh sebesar 1, 238 yang berarti bahwa hasil penelitian menunjukan tikat keanekaragaman ikan gelodok di kawasan mangrove pantai Kertomulyo Pati termasuk dalam kriteria sedang. Sedangkan untuk tingkat dominasi ikan gelodok diperoleh sebesar 0,31 yang termasuk dalam kategori sedang maka tidak ada spesies yang mendominasi, hal ini menunjukan produktivitas perairan tersebut cukup seimbang antara predator dan mangsa. Hasil pengukuran pH tanah berkisar 6,1- 6,5 dan memiliki tipe bersubstrat lumpur yang merupakan tipe habitat sesuai Periopthalmus sp.

The research was conducted from May to July 2022 in six zones to determine the diversity, niche width, distribution, and community structure of demersal fish. Fish were surveyed using a drift gillnet at a maximum depth of 15 m, identified, and analyzed using clusters and nMDS to determine their grouping. SIMPER analysis was used to discover individual variations between zones and depth strata, while ANOVA was used to determine the significance of individual fish observed. The results of the study found 8 species, 8 genera, and 8 families with Eubleekeria splendens as well as Chelonodon patoca having the highest niche widths (04.42 dan 04.33), then E. splendens, Terapon jarbua, Scatophagus argus, Plotosus canius, C. Patoca, and Johnius carouna were relatively abundant (frequency > 80%). Aside from that, J. carouna is the fish with the most individuals discovered (82 ind and 32.54%). Cluster analysis and nMDS are divided into two groups, with J. carouna being the differentiator between fish groupings based on zonation and C. chanos, C. patoca, and J. carouna being the differentiator between fish groupings based on depth strata. Furthermore, the ANOVA test reveals that individual demersal fish between zones have a significance of < 0.05, whereas individual demersal fish between depth strata have a significance of > 0.05.
