Penelitian dilakukan pada Februari-Desember 2012 di Kuandang, Kabupaten Gorontalo Utara. PPP Kuandang adalah pelabuhan baru yang masih membutuhkan data-data terkait sumberdaya ikan, salahsatunya adalah tenggiri. Tujuan penelitian ini adalah untuk mengetahui aspek penangkapan meliputi produksi, komposisi, laju tangkap dan daerah penangkapan; aspek biologi seperti frekuensi panjang, hubungan panjang berat, faktor kondisi, panjang pertama kali tertangkap, dan kebiasaan makan; aspek biologi reproduksi meliputi: Tingkat Kematangan Gonad, Index Kematangan Gonad, perbandingan jenis kelamin, musim pemijahan, panjang pertama kali matang gonad, diameter dan jumlah telur. Metode pengukuran ikan tenggiri (Scomberomorus commerson) diambil secara acak dari hasil tangkapan purse seine dan handline. Frekuensi panjang diperoleh dengan mengelompokkan ukuran ikan dengan interval kelas 6 cm. Ikan tenggiridi Teluk Kuandang melimpah pada Mei-Juli. Distribusi frekuensi panjang pada kisaran 25-138 cm denganyang didominasi ikan tenggiri yuwana 61.2%, dan ikan dewasa 38.8%.Ukuran pertama kali tertangkap dari pajeko lampu dan pancing ulur masing-masing 64.7 cm dan 71.9 cm. Hasil uji-t terhadap nilai b hubungan panjang berat diperoleh sifat pertumbuhan ikan tenggiri pada Februari-April, Juli, Agustus, Oktober adalah isometrik; Mei-Juni alometrik negatif, September alometrik positif; dan November-Desember alometrik negatif. Ikan tenggiri di Teluk Kuandang memijah pada Mei-Juli. Perbandingan kelamin rata-rata ikan jantan dan betina adalah1,3:1. Panjang pertama kali matang gonad ikan tenggiri adalah 80.4 cm, kisaran 79.3-81.6 cm. Jumlah telur ikan tenggiri berkisar 417.360-9.476.520 butir, rata-rata 3.419.663 butir pada kisaran panjang 65-103 cm. Diameter telur pada TKG IV ditemukan pada bulan Juni, Agustus, dan November.Kebiasaan makan ikan tenggiri adalah ikan layang, teri, lemuru, petek, dan cumi-cumi. ......The study was conducted in February-December 2012 at Kuandang, North Gorontalo regency. Kuandang fishing port is a new port that still require resource data related to fish, one of them is the spanish mackerel. The purpose of this study was to determine the fishing aspects include production, catch composition, catch rates and fishing ground; biological aspects such as length frequency, length weight relationship, condition factor, length at first capture, and food habits; and an aspects of reproductive biology include: gonad maturity stage, gonadosomatic index, sex ratio, spawning season, length at first maturity, diameter and number of eggs. Methods to measurement of spanish mackerel was taken random from the catch of the purse seine and handline. Length frequencies was obtained by grouping fish by size class interval 6 cm.Spanish mackerel in the Kuandang Bay abundant in May-July. Length frequency distribution in the size range of 25-138 cm with predominantly immatureand mature 61.2% and 38.8% respectively. The result of t-test on the b value fromlength weight relationshipwas obtained that spanish mackerel growth in February to April, July, August, October was isometric; May to June was allometric negative;September was allometric positive, and November-December was allometric negative.Relative condition factor in June was lowthey have spawned. Spanish mackerel in Kuandang Bay spanedinMay-July. The ratioof male and female was1,3:1. While length at first maturity was about 80.4 cm, size range 79.3-81.6 cm. The number of spanish mackerel eggs between417.360-9.476.520 grains, the average is 3.419.663 grain, with size range between 65-103 cm. An eggs diameter of stage IV of maturity was found in June, August, and November. Food habits of spanish mackerel are scads, anchovies, clupeids, ponyfish, and squid.

Menurut data dari United Nations Development Program (UNDP), perairan Indonesia merupakan habitat bagi 76% terumbu karang dan 37% ikan karang dunia. Menurut data Kementrian Kelautan dan Perikanan Indonesia, jumlah potensi ikan di lautan Indonesia adalah sebesar 12,54 juta ton pertahun. Namun, Indonesia masih belum bisa memanfaatkan potensi tersebut karena jumlah produksi perikanan tangkap di Indonesia masih sebesar 6,83 ton per tahun. Salah satu alat tangkap perikanan di Indonesia adalah bagan apung yangmemiliki produktivitas yang baik untuk menangkap ikan. Selain itu, SDA nonhayati Indonesia pun melimpah,seperti minyak bumi misalnya. Namun, Ilmuwan memprediksi bahwa energi minyak bumi Indonesia tersebut akan habis pada 2030. Jika Indonesia masih bergantung kepada energi fossil tersebut dan tidak mencari energi alternatif, maka dikhawatirkan Indonesia tidak siap menghadapi kehidupan yang akan mendatang. Selain ketersediannya mulai menipis, energi fossil pun memberikan dampak yang buruk terhadap lingkungan. Menurut Intergovernmental Panel On Climate Change (IPCC), 1 liter BBM jenis premium dapat menghasilkan 2,35 Kg gas CO2. Jika satu bagan Apung berukuran 10 meter x 9 meter membutuhkan 1.907 Liter selama setahu, maka gas CO2 yang dihasilkan sebesar 4.481 Kg. Salah satu usaha yang dapat dilakukan untuk mengurangi emisi tersebut adalah dengan cara mengganti BBM menjadi tenaga surya yang ramah terhadap lingkungan. Selain itu, penggunakan Pembangkit Listrik Tenaga Surya pun lebih menguntungkan daripada pembangkit listrik generator set dalam jangka waktu minimal 4 tahun. ......According to data from the United Nations Development Program (UNDP), Indonesian waters are a habitat for 76% of the world's coral reefs and 37% of reef fish. According to data from the Indonesian Ministry of Maritime Affairs and Fisheries, the potential number of fish in Indonesia's oceans is 12.54 million tons per year. However, Indonesia is still unable to exploit this potential because the amount of capture fisheries production in Indonesia is still 6.83 tons per year. One of the fishing gear in Indonesia is a floating fishing platform that has good productivity for fishing. In addition, Indonesia's non-biological natural resources are abundant, such as petroleum for example. However, scientists predict that Indonesia's petroleum energy will run out by 2030. If Indonesia still relies on fossil energy and does not look for alternative energy, then it is feared that Indonesia is not ready to face life to come. In addition to its diminishing availability, fossil energy also has a bad impact on the environment. According to the Intergovernmental Panel on Climate Change (IPCC), 1 liter of premium fuel can produce 2.35 kg of CO2 gas. If a floating meter measuring 10 meters x 9 meters requires 1,907 liters for one year, the CO2 gas produced is 4,481 kg. One effort that can be done to reduce these emissions is by replacing fuel into solar power that is friendly to the environment. In addition, the use of solar power plants is more profitable than generating sets for a minimum of 4 years.
