Abstract

Nike fish is one of the fish species found in Gorontalo known to belong to the Gobiidae group. Nike is fishing intensively by local fishermen without considered sustainability aspect. Unfortunately, the comprehensive scientific data for the management purposes of nike fish was not yet available. Therefore, this study aims to assess the period of occurrence of nike fish in the Gorontalo Bay as the initiation of providing scientific information that supports sustainable management goal. Sampling was conducted from March to June 2018 using fish net. The results showed that the period of occurrence of nike fish every month starting from the bay area and move toward the estuary. The emergence of nike fish that began in the eastern part of Gorontalo Bay occurred in March, April, and May 2018. While the appearance of nike fish that started from the western area of the bay occurred in June and July 2018. It was concluded that the duration of occurrence of nike fish in the Gorontalo Bay occurs for 3 to 9 days at the end of the lunar phase.Nike merupakan salah satu spesies ikan yang ditemukan di Perairan Gorontalo yang dikenal berasal dari kelompok gobiidae. Kegiatan eksploitasi ikan nike oleh nelayan belum mempertimbangkan aspek kelestariannya di perairan berpotensi mengancam keberlanjutannya di perairan. Data ilmiah dan komprehensif yang dapat dijadikan acuan pengelolaan ikan nike belum tersedia. Oleh karena itu, penelitian ini bertujuan untuk memetakan periode kemunculan ikan nike di perairan Teluk Gorontalo sebagai inisiasi penyediaan informasi ilmiah yang mendukung arah pengelolaan yang berkelanjutan. Pengambilan sampel ikan di Perairan Teluk Gorontalo dilakukan pada Bulan Maret sampai Juni 2018 dengan menggunakan jaring ikan. Hasil penelitian menunjukkan bahwa periode kemunculan ikan nike setiap bulan dimulai dari area teluk dan begerak ke arah muara. Kemunculan ikan nike yang dimulai di perairan Teluk Gorontalo bagian timur terjadi pada bulan Maret, April, dan Mei 2018. Sedangkan kemunculan ikan nike yang dimulai dari area barat teluk terjadi pada bulan Juni dan Juli 2018. Secara keseluruhan, durasi kemunculan ikan nike di perairan Teluk Gorontalo terjadi selama 3 sampai 9 hari di fase bulan akhir menjelang bulan baru.

Abstract

Highlight ResearchThe fishing area of S. leptolepis in this study was confirmed to be located in Tomini BayThe fish samples were gathered randomly from fishers' catch using purse seinesThe growth curve for the male and female fish data were both plotted following the trend of the Von Bertalanffy equationThis study estimates the growth parameters, mortality, and exploitation rates of the male and female fish separately.AbstractComprehensive data is required for implementing sustainable fisheries management. Population dynamic and stock assessment aspects of Selaroides leptolepis species in Tomini Bay have not been entirely reported. This study aimed to determine the fishing mortality rate and exploitation status of S. leptolepis in Tomini Bay by calculating Von Bertalanffy growth model parameters (L∞, K, t0) then plotting them into Pauly's empirical equation. The sampling was conducted monthly from April to September 2020 at Gorontalo City Fishing Port. Samples were collected randomly from five commercial fishing vessels shortly after the fishermen landed their catch at the fishing port. All fish samples were confirmed to be obtained by the fishermen from Tomini waters. The growth parameters of the samples were analyzed using FiSAT II based on Von Bertalanffy mathematical model. While the mortality and exploitation values were calculated manually using Pauly's equation. The study showed that the growth parameter values of S. leptolepis in Tomini Bay were 245.47 mm, 0.49/year, and -3.04/year for males, while 227.80 mm, 0.63/year, and -2.72/year for females separately for L∞, K, and t0. The total, natural, and fishing mortality rates were 3.06/year, 0.61/year, and 2.45/year for males and 0.99/year, 0.74/year, and 0.25/year for females. The analysis results showed that the female's natural mortality (M) was higher than the male. In contrast, the fishing mortality (F) and total mortality (Z) of male fish exceed the female. The exploitation value of males (E=0.80) was greater than that of females (E=0.26).

Abstract

Dua muara utama lokasi kemunculan ikan nike di Perairan Gorontalo adalah Muara Bone dan Muara Paguyaman yang secara administratif masing-masing terletak di Kota Gorontalo dan Kabupaten Boalemo, Provinsi Gorontalo. Tujuan penelitian ini adalah membandingkan karakter morfometrik serta menentukan sebaran frekuensi panjang, pola pertumbuhan, dan faktor kondisi ikan nike yang ditemukan di Muara Bone dan Muara Paguyaman. Total sampel secara random sebanyak 700 hingga 2275 ekor dikumpulkan dari perairan dengan menggunakan tagahu dalam dua musim penangkapan, yaitu Juli dan September 2021. Sampel diawetkan dengan menggunakan es batu dan segera dilakukan pengukuran panjang total, panjang standar, tinggi badan, lebar badan, diameter mata, diameter kepala, dan bobot tubuh. Hasil penelitian selama dua musim penangkapan menunjukkan bahwa ukuran morfometrik ikan nike di Muara Paguyaman relatif lebih besar dibandingkan dengan nike yang ditemukan di Muara Bone. Sebaran frekuensi panjang nike per hari kemunculan mengindikasikan schooling nike yang ditemukan pada setiap musim penangkapan tersusun dari populasi multi kohort. Pola pertumbuhan nike selama penelitian adalah alometrik positif dan alometrik negatif. Adapun kisaran nilai faktor kondisi rata-rata ikan nike di Muara Bone dan Paguyaman masing-masing adalah 0,970-1,044 dan 0,888-1,431.The two main water areas in Gorontalo for the emergence of nike fish are Bone and Paguyaman Estuaries. Each ecosystem is administratively located separated in Gorontalo City and Boalemo Regency, Gorontalo Province. The research aimed to compare the morphometric characters and to determine the distribution of length frequencies, growth patterns, and condition factors of the nike found in those estuaries. A total random sample of 700 to 2275 individuals were caught from the waters using tagahu during fishing seasons, July and September 2021. The samples were preserved using ice cubes and immediately measured for total length, standard length, body height, body width, eye diameter, head diameter, and body weight. The data showed that the morphometric size of the nike in the Paguyaman Estuary was relatively larger compared to those found in the Bone Estuary. The length frequency distribution per day of nike appearance indicates that schooling from each season was composed of a multi-cohort population. Nike's growth pattern during the study was positive allometric and negative allometric. The range of condition factor values for the average nike fish in Muara Bone and Paguyaman were 0.97 – 1.044 and 0.888 – 1.431, respectively.

Abstract

Selar termasuk komoditas ikan laut yang bernilai ekonomis karena permintaan pasar yang tinggi dan didukung oleh ketersediaan populasi di alam sepanjang tahun.  Truss morfometrik ikan merupakan salah satu karakter terukur yang umum diterapkan dalam studi morfologi ikan sebagai potensi pembeda seksual ikan pada spesies tertentu. Tujuan penelitian ini adalah menyajikan informasi mengenai morfologi, menentukan rasio truss morfometrik terhadap panjang tubuh total yang dapat dijadikan karakter pembeda seksual, serta membandingkan pola pertumbuhan Selar crumenophthalmus jantan dan betina. Jumlah sampel sebanyak 100 ekor dikumpulkan secara random di Tempat Pendaratan Ikan Tenda Kota Gorontalo selama dua hari penangkapan pada bulan Juni 2022. Hasil pengamatan morfologi menunjukkan bahwa bentuk tubuh S. crumenophthalmus adalah kompres dengan tipe sisik sikloid. Bagian dorsal tubuh berwarna biru gelap kehijauan, bagian ventral berwarna silver cenderung putih, terdapat area tipis berwarna kuning membujur dari batas operkulum sampai batang ekor pada sisi lateral tubuh yang terletak di atas linea lateralis, sirip kaudal berbentuk cagak dan simetris, memiliki rumus sirip DIX, 24-27 dan AIII, 21-23. Terdapat 14 truss morfometrik yang dapat dijadikan sebagai ciri pembeda S. crumenopthalmus jantan dan betina yaitu 1 karakter pada bagian kepala (A4), 6 karakter pada tubuh bagian anterior (B1, B2, B4, B5, B6, B9), 3 karakter pada tubuh bagian posterior (C2, C5, C6), dan 4 karakter pada bagian ekor (D1, D2, D3, D5). Adapun pola pertumbuhan spesies jantan dan betina pada sampel riset ini sama-sama bersifat allometrik positif. Selar is a marine fish commodity that has economic value due to high market demand and is supported by the availability of natural populations throughout the year. Fish morphometric truss is one of the measurable characteristics that is commonly applied in the study of fish morphology as a potential sexual differentiation of fish in certain species. The aim of this research is to present information regarding morphology, determine the ratio of morphometric truss to total body length which can be used as a sexual distinguishing character, and compare the growth patterns of male and female Selar crumenophthalmus. A total of 100 samples were collected randomly at the Gorontalo City Tent Fish Landing Site during two days of fishing in June 2022. The results of morphological observations showed that the body shape of S. crumenophthalmus was compressed with cycloid scale type. The dorsal part of the body is dark greenish blue, the ventral part is silver, and tends to be white, and there is a thin yellow area stretching from the border of the operculum to the caudal peduncle on the lateral side of the body which is located above the linea lateralis, the caudal fin is forked and symmetrical, has the fin formula DIX, 24-27 and AIII, 21-23. There are 14 morphometric trusses that can be used as distinguishing characteristics of male and female S. crumenopthalmus, namely 1 character on the head (A4), 6 characters on the anterior body (B1, B2, B4, B5, B6, B9), 3 characters on the body the posterior (C2, C5, C6), and 4 characters in the tail (D1, D2, D3, D5). The growth patterns of male and female species in this research sample were both positive allometric.

Abstract

This study presents a comprehensive checklist of sea cucumber species found in Biluhu Timur waters, Tomini Bay, Gorontalo, Indonesia, across the new moon and full moon lunar phases. The survey identified eight species across five genera, including Actinopyga miliaris, A. mauritiana, Holothuria scabra, and H. leucospilota, noting significant distribution patterns influenced by lunar cycles and different biomes at three stations. Actinopyga miliaris and A. mauritiana, both classified as Vulnerable, were more active in the seagrass biome of Station I during the full moon. H. leucospilota, classified as Least Concern, was highly prevalent in the sandy substrate biome of Station II during the new moon, indicating a strong ecological association with that habitat. Stichopus horrens, classified as Data Deficient, showed notable activity in the coral reef biome of Station III. Environmental parameters such as water temperature, salinity, and pH were measured at each station to understand the conditions influencing these species. This study highlights the importance of lunar phases, biomes, and environmental variables on sea cucumber distribution. The findings underscore the need for conservation efforts that consider these factors to protect species vulnerable to overfishing and habitat degradation. Further research should include genetic analysis and expanded temporal and spatial scales to develop effective conservation strategies and sustainable management practices
