Abstract

This research aims to determine the diversity and zoning patterns of mangroves in Otiola Village, Ponelo Islands District, North Gorontalo Regency. Data collection was carried out from January to February 2021. The sampling method used quadrant line transects and the method for determining mangrove zoning was based on three zoning divisions, namely, proximal, middle and distal. The research location is divided into 4 stations, and each station consists of 5 transect lines. Diversity was calculated using the Simpson Diversity Index formula. The research results show that in Otiola Village there are 20 types of mangroves. The diversity index for the tree category is in the medium to high category (0.632 – 0.873) and for the sapling level it is in the low, medium to high category (0.489 – 0.876), while the seedlings are in the medium to high category (0.674 – 0.831). The mangrove zoning in Otiola Village is classified as impure zoning because there are several species that vary in each zoning (mixed).

Abstract

Perikanan ikan nike di perairan Desa Bilato, Kabupaten Gorontalo, merupakan salah satu sumber pendapatan penting bagi masyarakat pesisir di wilayah Teluk Tomini. Aktivitas penangkapan dilakukan menggunakan alat tangkap tagahu yang dioperasikan secara berkelompok pada saat musim kemunculan ikan. Penelitian ini bertujuan untuk mengetahui produksi ikan nike menggunakan alat tangkap tagahu serta menghitung nilai manfaat langsung yang diperoleh nelayan. Penelitian ini dilaksanakan pada bulan Juni hingga Agustus 2024 di Desa Bilato, Kecamatan Bilato, Kabupaten Gorontalo dengan menggunakan pendekatan kombinasi kualitatif dan kuantitatif melalui metode survei, observasi partisipatif, dan wawancara mendalam terhadap nelayan pengguna tagahu. Data dianalisis secara deskriptif, sedangkan nilai manfaat langsung dihitung berdasarkan hasil tangkapan per trip dikalikan harga jual dan dikurangi biaya operasional. Hasil penelitian menunjukkan bahwa produksi ikan nike bersifat musiman dengan fluktuasi yang signifikan. Total produksi pada musim pertama sebesar 3.450 kg dengan nilai Rp49.150.000,-, menurun pada musim kedua menjadi 1.775 kg dengan nilai Rp30.650.000,-, dan meningkat pada musim ketiga menjadi 4.900 kg dengan nilai Rp68.700.000,-. Rata-rata produksi per nelayan tertinggi terjadi pada musim ketiga (612,50 kg), sedangkan terendah pada musim kedua (221,88 kg). Nilai manfaat langsung juga menunjukkan variasi antar nelayan, dengan kisaran Rp1.350.000,- hingga Rp16.300.000,- per musim. Perbedaan tersebut dipengaruhi oleh kapasitas alat tangkap, jumlah armada, serta intensitas penangkapan. Secara keseluruhan, perikanan nike di Desa Bilato memberikan kontribusi ekonomi yang nyata, namun distribusi manfaatnya belum merata. Oleh karena itu, diperlukan pengelolaan yang mempertimbangkan pengaturan kapasitas usaha, efisiensi operasional, serta kondisi lingkungan estuari untuk menjaga stabilitas produksi dan pendapatan nelayan.

Abstract

The overpopulation of suckermouth catfish (Pterygoplichthys spp.), an invasive species in Lake Limboto, has significantly impacted local fish biodiversity and fishing productivity in Limehe Timur Village, Gorontalo. This community service program aimed to transform ecological pressure into economic potential by training local residents, particularly housewives and youth groups, to process suckermouth catfish into fish meal. The activity was conducted through participatory methods, including technical lectures, hands-on training, and group demonstrations. The training covered fish selection, cleaning, steaming, controlled drying, grinding, and hygienic packaging using simple household equipment. Results indicated an increase in participants' knowledge and skills, as well as heightened interest in utilizing invasive fish as an alternative protein source. The program also introduced basic product quality parameters and emphasized the importance of safe processing practices. This initiative created opportunities for income diversification and household-scale enterprise development. The success of this program highlights the potential of integrated, locally adapted empowerment initiatives in managing invasive species while simultaneously enhancing community livelihoods.

Morphometric and genetic variations of species composers of nike fish assemblages in Gorontalo Bay Waters, Indonesia. Biodiversitas 21: 4571-4581.  Nike is Gobioidei fish at the post-larval and juvenile stages whose habitat is still in seawater before they migrate to the freshwater, grow up, and spawn to fulfill their life cycle as an amphidromous species. This study aims to identify the species composers of Nike fish in Gorontalo Bay waters based on their morphometric and molecular characters. 2,523 samples were collected from the catches of fishermen during three periods of their appearance in Gorontalo Bay waters from January to March 2019. The samples were grouped based on their similarity of melanophore patterns, and morphometric characters of 10 units were then measured. This study found 20 different groups of melanophore patterns; 15 of them were new melanophore patterns. DNA samples from each group of new melanophore patterns were then isolated for molecular analysis. The morphometric analysis grouped the 20 melanophore patterns into three separate clusters that were confirmed through molecular analysis. The results of Gen Cytochrome Oxidase I (COI) sequences indicate that the new melanophore patterns of Nike fish assemblages consisting of six species; five species in the Gobiidae family (i.e. Sicyopterus parvei, S. cynocephalus, S. longifilis, S. lagocephalus, and Stiphodon semoni) and a species in the Eleotridae family (Belobranchus belobranchus).

Abstract. Sahami FM, Habibie SA. 2021. Diversity of species in making up Nike fish schools and a new record of Eleotris melanosoma in Tomini Paguyaman Bay, Gorontalo, Indonesia. Biodiversitas 22: 5459-5467. Several estuaries in the waters of Tomini Bay are reported as the primary location for Nike fishing in Gorontalo; one of which is Paguyaman Bay. However, scientific information on Nike fish in the Tomini Bay waters is currently limited in Gorontalo Bay. The present study aims to determine the diversity of species in making up the Nike fish schools in Paguyaman Bay and show the types of constituent species whose distribution in Gorontalo waters has never been reported. A total of 1773 samples of Nike fish were collected from the sea to the estuary of Paguyaman Bay in one period of their emergence on April 8-10, 2021. The species were grouped based on the melanophore pattern’s similarity and then analyzed morphometrically. The molecular identification of COI mitochondrial DNA was performed on species with different morphological appearances from those found in Gorontalo Bay. The Discriminant Function Analysis (DFA) indicated that the main distinguishing character of morphometrics is body depth. The morphological results suggested that the Nike fish schools in Paguyaman Bay consisted of seven species, four genera, and two families, i.e., Sicyopterus longifilis, S. parvei, S. cynocephalus, Stiphodon semoni, Belobranchus segura, B. belobranchus, and Eleotris melanosoma. The first finding of E. melanosoma as a species making up the Nike fish schools in Paguyaman Bay was a new variant of the distribution of this species in Gorontalo waters and confirmed using morphology and molecular analysis. Further, based on the species composition, Nike fish schools in the waters of Paguyaman Bay show a typical species dominance trend during the recruitment process returning to freshwater, i.e., S. longifilis (52%) on the first day, Belobranchus segura (63.27%) on the second day, and Stiphodon semoni (83.43%) on the third day.
