ABSTRAK Pelabuhan Perikanan Pantai Tawang merupakan pelabuhan yang cukup besar di Kabupaten Kendal. Salah satu hasil tangkapan yang didaratkan yaitu ikan Swanggi (Priacanthus tayenus) merupakan jenis ikan demersal dengan karakteristik khusus berwarna merah muda, memiliki mata besar dan pada sirip perutnya terdapat bintik berwarna kehitam-hitaman. Tujuan penelitian ini adalah mengetahui aspek biologi ikan Swanggi meliputi struktur ukuran, hubungan panjang berat, faktor kondisi (Kn), ukuran pertama kali tertangkap (Lc50%), ukuran pertama kali matang gonad (Lm50%), tingkat kematangan gonad (TKG), indeks kematangan gonad (IKG), diameter telur, fekunditas dan upaya pengelolaan sumberdaya ikan Swanggi (Priacanthus tayenus). Penelitian dilaksanakan pada bulan Maret – April 2016. Metode penelitian adalah survei. Pengambilan sampel menggunakan metode random sampling atau acak. Hasil penelitian dilakukan pada ikan Swanggi sebanyak 625 ekor, pertumbuhan ikan Swanggi bersifat allometrik negatif dengan persamaan W = 0,00045L2,30701. Panjang ikan yang tertangkap selama penelitian berkisar antara 105 – 324 mm dan  berat berkisar antara 22 – 205,2 gram. Nilai faktor kondisi adalah 1,106. Nilai Ukuran pertama kali tertangkap (Lc50%) adalah 152 mm.Ukuran pertama kali matang gonad (Lm50%) yaitu 153 mm. Ikan Swanggi jantan maupun betina sebagian besar belum matang gonad. Nilai TKG yang semakin tinggi akan diikuti dengan tingginya nilai IKG dan diameter telur juga semakin besar. Fekunditas tertinggi sebesar 245303 butir. Hubungan fekunditas terhadap panjang dan berat ikan Swanggi menunjukkan koefisien korelasi lemah. Kata Kunci : Ikan Swanggi  (Priacanthus tayenus), Aspek Biologi, PPP Tawang  ABSTRACT Tawang Coastal Fishing Port is a huge port in Kendal Regency. One of its hauls which was landed is Red Bigeye fish (Priacanthus tayenus). Which include in demersal fish with special characters; they have pink color, big eyes, and black spots around their pelvic fins. The purpose of this research is to find out the biological aspect of Red Bigeye fish from several aspects, i.e. size of the structure, relation of length and weight, the conditions factor (Kn), the size of the first caught (Lc50% ), the first time size of gonad maturity (Lm50%), gonad maturity level (TKG), index of gonad maturity (IKG), diameter of egg, fecundity, and management effort of Red Bigeye fish (Priacanthus tayenus) resources. The research was conducted in March – April 2016. The method used in this research is survey. In taking sample, this research use random sampling method. The result was done on 625 Swanggi fish. The growth of Red Bigeye fish is negative allometric with equation W = 0,00045L2,30701. The length of caught fish for the research are around 105 - 324 mm and weight around 22 – 205,2 gram. The value of condition factor is 1,106. The value of first time caught is 152 mm. The value of first time mature gonad (Lm50%) is 153 mm. Most male and female Red Bigeye fish are immature gonads.

ABSTRAK : Rajungan merupakan komoditas perikanan bernilai ekonomis penting dan memiliki nilai komersial yang cukup tinggi. Salah satu desa yang memproduksi rajungan adalah Desa Betahwalang. Sebagian besar rajungan hasil tangkapan di perairan Betahwalang dikirim untuk di ekspor ke luar negeri. Tingginya permintaan pasar terhadap komoditas perikanan rajungan memicu eksploitasi yang berlebihan sehingga dapat berdampak terhadap kelestarian sumber daya rajungan. Tujuan penelitian ini adalah untuk menganalisis sebaran lebar karapas dan proporsi EBF (egg berried female) rajungan di Desa Betahwalang, Demak terkait dengan upaya pengelolaan rajungan secara berkelanjutan sesuai dengan Peraturan Menteri Kelautan dan Perikanan no. 1 tahun 2015. Penelitian ini dilaksanakan pada bulan Februari – Maret 2019 di Desa Betahwalang, Demak menggunakan metode random sampling. Pengukuran rajungan dilakukan di bakul yang ada di Desa Betahwalang, Demak. Hasil penelitian menunjukkan bahwa 1003 ekor rajungan (83%) yang tertangkap berukuran >10 cm dari total 1203 rajungan tertangkap. Nisbah kelamin di Desa Betahwalang menunjukkan bahwa antara jantan dan betina seimbang (1:1,06). Sedangkan untuk betina bertelur yang tertangkap (EBF) berjumlah 81 ekor rajungan (13%). ABSTRACT : Blue Swimming Crab is one of fisheries commodity with highly important economical and commerce value. One of the village that produce blue crab is Betahwalang. Most of the crabs are exported. With high demand of blue crab resulting in over exploitation that affects the population of blue crab. The purpose of this research is to analyze the spread of carapace width and the proportion of EBF (Egg Berried Female of the blue swimming crab in Desa Betahwalang, Demak that are related with the continuous management effort of blue crab consistent with Peraturan Menteri Kelautan dan Perikanan No 1 Tahun 2015. This research was conducted on February – March 2019 at Desa Betahwalang, Demak using random sampling method. The measurement of blue crab was done on the buyer at Desa Betahwalang, Demak. The results show that 1003 blue crab (83%) that were caught had carapace width more than 10 cm from 1203 blue crab caught. The ratio of male and female crab show that male and female were equal (1:1,06). For the egg berried female (EBF) that were caught shows 81 blue crab caught (13%).
