his research was conducted in November to December 2012 which aimed to estimate thepopulation dynamic of mackerel fish through their age-group, growth, mortality, and yield perrecruitment. Samples were taken from the waters of sub district of Panyula, in the district of EastTanete Riatang, in Bone Region. Age-group was measured using Bhattacharya method with thehelp of Fish Stock Assessment Tools II (FISAT II) software. Growth and natural mortality weremeasured by applying the equations of Von Bertalanffy and Empiris Pauly (respectively). Whereastotal mortality as well as yield per recruitment were estimated by applying Beverton and Holdequation; and catch mortality was estimated by applying the equation of Z=F+M. Results showedthe average total length of 849 mackarel fish that was 121-295 mm. They were divided into 4groups with 306.35 mm asymptotic length, 0,33 growth rate coefficient and theoritical age of 0.0294year. Natural mortality rate, total and catch mortality, and exploitation rate were 0.3672per year; 2,4358 per year, 2,0687 per year and 0.8493 (respectively). This indicated that an overcatch had occurred due to the higher catch mortality compared to the natural mortality as well asthe yield per recruitment, i.e. 0.0865 gram/recruitment. Keywords : Population dynamic, mackerel fish, Bone Strait.

Black Cumin Seeds (Nigella sativa L.), commonly known as black seed, have been used in traditional medicine.Streptococcus agalactiae is a Gram-positive bacteria that causes the disease Streptococcosis in nile tilapia(Oreochromis niloticus L.). This study aims to find the bioactivity of black cumin seeds (N. sativa L.) againstbacterial pathogens in nile tilapia (O. niloticus L.). The research activities include preparation of samples blackcumin seeds (N. sativa L.), extraction with kinetic maceration method using solvents from different polarity (nhexane,ethanol and methanol), determination of antibacterial activity and minimum inhibition concentration(MIC) by agar diffusion method. The results of antibacterial activity against S. agalactiae of pathogenic bacteriashowed that the highest activity was performed by semi-polar extract ethanol (inhibition zone diameter of 15.33mm), followed by extract polar methanol with inhibition zone diameter of 12.67 mm. Extract non-polar nhexanedid not show any activities against the bacterial test. Determination of the minimum inhibitoryconcentration (MIC) of ethanol extract against S. agalactiae showed a value of 250 ppm. Keywords: Antibacteria, Streptococcus agalactiae, Nile Tilapia (Oreochromis niloticus L.), Nigella Sativa L

Penelitian ini bertujuan untuk menganalisis kemampuan indeks kondisi kerang hijau (Perna viridis) dalammendeteksi pengaruh pengasaman laut terhadap toksisitas logam Pb. Penelitian dilaksanakan di LaboratoriumPenangkaran dan Rehabilitasi Ekosistem Laut Fakultas Ilmu Kelautan dan Perikanan, Universitas Hasanuddin. Rancangan yang digunakan dalam penelitian ini adalah rancangan faktorial. Kerang hijau dengan ukuranpanjang 5-6 cm diberi perlakuan dengan paparan konsentrasi logam Pb 0 mg/l (kontrol), 0,008 mg/l, 0,08 mg/ldan 0,8 mg/l, pada kondisi pH (level asidifikasi) air media hidup yaitu 6,2, 7,7, 8,2. Pemaparan dilakukanselama 96 jam. Pengukuran indeks kondisi dilakukan dengan mengukur panjang, tinggi, lebar, berat dagingkering, dan volume ruang internal cangkang. Nilai indeks kondisi dianalisis dengan analisis varian desainfaktorial. Hasil analisis menunjukkan terdapat pengaruh signifikan konsentrasi logam Pb terhadap penurunannilai indeks kondisi kerang (p<0.05). Pengaruh logam Pb terjadi pada CI 1, CI 3 dan CI 4. Meskipun perlakuan pH tidak menunjukkan pengaruhnya terhadap indeks kondisi, tetapi secara statistik diketahui bahwa terdapat interaksi antara pH dan Pb dalam memengaruhi indeks kondisi C1 dan C3 (p<0,05). Hal ini menunjukkanperlakuan pH memunyai peran dalam toksisitas logam Pb terhadap penurunan nilai indeks kondisi kerang hijau.Kata kunci :Indeks kondisi, Biomarker, Logam Pb, Perna viridis, Penagasaman laut

One way to detect the presence of the White Spot Syndrome Virus in several organs Vaname shrimp(Litopenaeus vannamei) were infected with the method of Polymerase Chain Reaction (PCR). WSSV virus isknown to attack various target organs, but it is difficult to detect early on shrimp. Therefore, this study aims todetect the presence of the distribution of White Spot Syndrome Virus in several organs Vaname shrimp(Litopenaeus vannamei) were infected with the Polymerase Chain Reaction method in order to early detectionefforts for the prevention and treatment of diseases caused by the virus. Organ observed that the swimming legs,gills, stomach and antennal gland. Research stages include sample preparation and DNA extraction, DNAamplification and electrophoresis. DNA extraction was performed using the method DTAB and CTAB-DNAamplification is done by using nested PCR. The emergence of DNA bands is an indicator of the presence ofWSSV in shrimp Vaname several organs which are then presented desktriptif. The results showed four WSSVinfected organs were observed. Based on the appearance, the entire sample of the swimming leg and antennalgland positively infected, then successively gills and stomach. The swimming leg can be used to diagnose thedisease early on shrimp WSSV Vaname without turning off the shrimp.Keywords : Distribution, Vanname shrimp, WSSV, PCR

This research was conducted to investigate the sex ratio and the first gonadal maturity size of mackerel fish(Decapterus macrosomas Bleeker 1841). Samples were taken from June to October 2013 in the sub-district ofPanyula, District of East Riattang, in Bone region. Sample analysis was conducted at the Fisheries biologylaboratory, Department of Fisheries, Hasanuddin University, Makassar. Sex ratio was analyzed by using chiquadrat-testwhereas the first gonadal maturity size was obtained from the first size of the third-gonadal-maturitystage. There were 782 fish collected with male to female ratio 1,02:1,00. Statistically, the sex ratio from Bone waterswas 1:1, in other words, it is still in a balance condition. The male fish reached gonadal maturity stage at the size of195 mm, whereas the female at 210 mm. Keywords: sex ratio, gonadal maturity size, Mackarel fish, Bone strait.

Tidak dapat dipungkiri bahwa usaha budidaya udang intensif merupakan kegiatan ekonomi di kawasan pesisiryang sangat produktif dalam peningkatan kesejahteraan masyarakat, PAD dan devisa negara, namun legitimasikeberlanjutan sangat ditentukan oleh dampak kerusakan lingkungan yang ditimbulkannya. Penelitian inibertujuan untuk : (1) melakukan analisa kelayakan dalam pengembangan budidaya tambak pada lahan marjinal;(2) menetapkan kesesuaian pengembangan teknologi tradisional, semi-intensif, dan intensif pada lahan tambakmarjinal. Pengamatan data primer berupa pengukuran dan pengamatan kesesuaian bioteknik aspek saranaprasarana,dan data sekunder berupa hasil penelitian dan data-data dari beberapa instansi yang terkait.Hasilpenelitian ini menunjukkan bahwa analisis kelayakan bioteknik dalam pengembangan budidaya tambak padalahan marjinal dilokasi penelitian pada musim hujan untuk metode tradisional adalah seluas 79,9 Ha, untukmetode semi-intensif seluas 356,31 Ha, dan untuk metode intensif adalah seluas 365,03 Ha. Sedangkanpengembangan pada musim kemarau untuk metode tradisional adalah seluas 43,12 Ha, untuk pengembanganmetode semi-intensif adalah seluas 282,7 Ha dan untuk pengembangan metode intensif adalah seluas 475,4 Ha.
