"The study on the dimethylformamid (DMF) optimization for maintenance sperm quality of the carp fish (Cyprrnus carpio L.) post-thawing has been performed. Sperm were collected by stripping method and were dissolved in the extender solution (DMF : Kurokura solution = 1 : 3). DMF concentrations were 0%, 5%, 10%, and 15%, respectively. The soluble sperm were kept on the 0.2mL of straw and were cryopreserved by the slow freezing method.Sperm analysis were carried out at the time of collection, post-equilibration, and post-thawing, respectively. Some parameters of the sperm quality observed were spermatozoa motility, viability, and abnormality. All data were analyzed by Analysis of Varians (ANOVA). DMF 10% were significantly (cc = 0.01) kept spermatozoa motility, viability, and abnormality relatively higher than DMF 0%, 5%, and 15%. These results suggest that DMF 10% is the optimize condition for maintenance sperm quality post-thawing."

"This research develops model for optimalization of the coastal zone for brackish water fishponds. the research has been conducted in gresik, East Java by using the survey method and collecting secondary data from the other reseachers and related instutions...."

"Port development pattern that is expected to be a fishing port can enhance economic growth and community of fisherman in the port development area. The purpose of this study is to analyze the internal and external factors., as well as referrals to formulate the development planning strategies in PPN Prigi. Research method used is descriptive analytical, using the strangths weakness Opportunity threats (SWOT) analysis of Quantitative Strategic Planning matrix (QSPM). The result of this study indicate that the internal factors are greater than the influence of external factors in the development of PPN Prigi. As for the development of PPN Prigi support an aggresive growth policy (Oriented Growth Strategy). QSPM obtained from the analysis that the institution takes precedence in the development compared with the alternative implementation of integrated policy strategy."

"ABSTRAKIkan Layur termasuk dalam superfamili Trichiuroidea dan merupakan salah satu ikan dasar demersal . Ikan Layur merupakan bahan baku usaha pengolahan ikan asap. Fenomena penurunan sumberdaya Ikan Layur di perairan Teluk Prigi dan sekitarnya dapat menjadi ancaman keberlanjutan usaha ikan asap. Penelitian ini bertujuan untuk menentukan status dan strategi keberlanjutan usaha ikan asap di Kawasan Teluk Prigi. Metode yang dilakukan meliputi aspek biologi dengan faktor kondisi dan metode surplus produksi, status keberlanjutan menggunakan metode rapfish dan strategi keberlanjutan dengan metode AHP.Aspek biologi Ikan Layur di perairan Prigi menunjukkan bahwa pertumbuhan ikan yang tertangkap dan didaratkan adalah alometrik negatif. Nisbah kelamin menunjukkan bahwa Ikan Layur betina lebih banyak dengan perbandingan 1:1,2. Berdasarkan TKG diketahui bahwa Ikan Layur yang tertangkap kebanyakan pada TKG 4 dengan persentase sebesar 33,5 , sehingga banyak Ikan Layur yang tertangkap dalam kondisi matang gonad. Hasil grafik perhitungan CPUE, sumber daya Ikan Layur masih dapat ditingkatkan dengan meningkatkan upaya tangkap. Sumberdaya potensial lestari MSY sumberdaya Ikan Layur di perairan Prigi diestimasi sekitar 2.424.884 kg per tahun. Jumlah tangkapan yang diperbolehkan JTB sebesar 1.939.908 kg per tahun 80 dari potensi lestari . Tingkat pemanfaatan 5 sebesar 18,42 dari jumlah tangkapan yang diperbolehkan JTB .Status keberlanjutan usaha ikan asap di lokasi penelitian layak secara finansial dengan indeks keberlanjutan multidimensi diperoleh nilai sebesar 60,42 dengan urutan prioritas strategi yang perlu dilakukan adalah sebagai berikut fasilitasi peralatan pengolahan yang digunakan; bimbingan dan penyuluhan dalam penerapan cara pengolahan yang baik dan penerapan standar sanitasi higiene dalam proses pengolahan dan penanganan produk; pembentukan kelembagaan pengolah berupa kelompok-kelompok pengolah dan wadah komunikasi antar-pengolah.

ABSTRACTHairtail Trichirius Sp. is included in superfamily Trichiuroidea and grouped as a demersal fish. It is one of raw materials for smoked fish product. The decreasing of population of the fish in Prigi Gulf could be a jeopardy for sustainability of smoked fish business in the area. This research was aimed to determine the level status of Hairtail population and to examine strategies for preserving the bussiness activity. Method used in this research includes biological and economical prespectives. To determine the danger level status AHP Technique was used.The results showed that according to biological prespective the growth of the fish population was algoritmic negatif. Sex ratio was 1 1,2 male to female respectively. According to Gonad Maturity Level GML , it is found that the majority of sample have GML Score 4 at 33,5 , so that the majority of sample has gonad in mature condition. CPUE graphic shows that the fish population still could be enhanched by improving fish catching technique. Potential sustainable yield of hairtail was estimated around 2.424.884 kg per year. Total Allowable Catch TAC was aqual to 1.939.908 kg per year 80 sustainable potency . Resources utility was equal to 18,42 TAC.On economical prespective, the business was estimated as financially visible since it has multidimensional sustainable index 60,42. Sequentially, strategies recomended for preserving the business activity are provision of processing equipment extension program on good and hygiene processing practices and establishment of information and communication center for fisherman and stake holders."

"Budidaya ikan bada (Rasbora argyrotaenia) secara ex-situ diperlukan untuk memenuhi kebutuhan sumber protein hewani masyarakat di sekitar Danau Maninjau, Sumatera Barat. Salah satu permasalahan umum dalam budidaya perikanan adalah senyawa nitrogen amoniak dan nitrit yang bersifat toksik bagi ikan. Kedua senyawa tersebut merupakan hasil dekomposisi secara mikrobiologis bahan-bahan organik, termasuk feses. Penelitian dilakukan di Puslit Limnologi LIPI selama 15 minggu dengan kepadatan ikan 4, 8, dan 12 ekor/akuarium. Pemantauan terhadap parameter pH, suhu, oksigen terlarut, amonia, nitrit, dan nitrat, dan produksi feses dilakukan setiap minggu selama 6 minggu. Adapun pertumbuhan dan sintasan ikan bada dipantau setiap minggu masing-masing selama 13 dan 15 minggu. Pada akhir pengamatan kadar amonia dan nitrat mengalami kenaikan di semua tingkat kepadatan ikan, sementara kadar nitrit berfluktuasi. Kadar amonia, nitrit, dan nitrat tertinggi di setiap pengamatan ditemukan pada kepadatan 12 ekor/akuarium, lalu berturut-turut diikuti oleh kepadatan 8 dan 4 ekor/akuarium. Pertumbuhan berat harian ikan bada selama 13 minggu pada kepadatan 12 ekor, 8 ekor, dan 4 ekor/akuarium masing-masing sebesar 0,0119 g, 0,0119 g, dan 0,0110 g. Sintasan pada 2 bulan pertama masing-masing 100%, sedangkan sintasan sampai 16 minggu pemeliharaan pada kepadatan 12 ekor/akuarium hanya mencapai 67%."
