To investigate the potential of extensive net cage culture for Nile tilapia (Oreochromis niloticus) fingerlings, an experiment was conducted in net cages suspended in a fertilized pond. Mixed-sex population of Nile tilapia with an average initial body weight of 0.065 g was used to stock in experimental cages. Four treatments; non added-substrate without supplemental feeding (NSNF), non added-substrate with supplemental feeding (NSAF), added-substrate without supplemental feeding (ASNF), and added-substrate with supplemental feeding (ASAF) were tested. The results indicated that addition of substrates which gave an additional submerged surface area of approximately equal to the total cage surface area did not show significant effect on the growth (p > 0.05). The fish gross yield obtained from non added-substrate cages without supplemental feeding was 1.22 kg/m3 for a 56-day period.DOI: http://dx.doi.org/10.3126/on.v10i1.7752

Culture Development

This study aims to examine the development strategy of Nile tilapia (Oreochromis niloticus) culture in Galela Lake, North Halmahera Regency, North Mollucas Province. It is a descriptive study. Data collection used direct observations, interviews, and literature studies, and data analysis applied SWOT analysis, and continued with Quantitative Strategic Planning Matrix (QSPM)).  Results revealed that there were 6 priority strategies taken to develop the culture of the nile tilapia (O. niloticus) as follows: 1. Human resources development; 2. Take advantage of the investment-providing institutions for culture development; 3. Optimize the use of nile tilapia culture in the floating net cage; 4. Broaden the marketing access; 5. Increase the fish seed quality and the product quality; 6. Agreement among the fish farmers to maintain security in the floating net cage localities.Keywords: strategy, Galela Lake, nile tilapia, SWOT, QSPM. ABSTRAKPenelitian ini bertujuan untuk mengkaji strategi pengembangan budi daya ikan nila (Oreochromis niloticus) di Danau Galela Kabupaten Halmahera Utara Provinsi Maluku Utara. Penelitan ini merupakan penelitian deskriptif. Teknik pengembilan data melalui observasi langsung dan wawancara, dan studi literature. Analisis data menggunakan analisis SWOT. Dan dilanjutkan dengan uji OSPM  (Quantitative Strategis Planning Matrix).  Hasil dari analisis data menghasilkan enam strategi prioritas untuk pengembangan budi daya ikan nila (oreochromis niloticus) yaitu 1. Peningkatan pembinaan SDM 2. Memanfaatkan lembaga penyedia modal untuk pengembangan budi daya 3. Optimalisasi lahan budi daya ikan nila di karamba Jaring apung (KJA) 4. Memperluas akses pemasaran 5. Peningkatan kualitas benih ikan nila dan kualitas produk 6. Kesepakatan antar pembudidaya dalam menjaga keamanan di lokasi karamba jaring apung (KJA).Kata Kunci : Strategi, Danau Galela, Ikan Nila, Analisis SWOT, Analisis QSPM

Average Body

The purpose of this study was to detect the presence of bacteria Aeromonas sp in tilapia (Oreochromis niloticus). Nine fish with an average body weight of 150-200 g were used in this study as samples. Sampling was conducted at three different locations which were representative of fish culture sites located on Lake Tondano. The number of sample gathered from each location was and 3 fish which were taken randomly. Fish samples were taken by using a scoop, then the samples were taken alive by placing in an oxygen-filled plastic separately and taken direcly to lab Fish Disease Control and Environmental Center, Tateli, Department of Marine and Fisheries of North Sulawesi province, for examination the presence of bacteria. Isolation of bacteria were conducted by taking samples from gill and kidney. This study was carried out from April - July 2013. Identification of the presence of bacteria was done through a series of observations of colony morphology and gram staining of bacteria, followed by a series of biochemical tests: oxidase test , catalase test , test TSIA , H2S production test , indole test , motility test , citrate test, and test O/F. It could be concluded that 22.22 % of farmed nile tilapia in Lake Tondano were infected with the Aeromonas sp with the following percentage from each site: Paleloan village 7.40% , 7.40% Toulimembet village, and 7.40% Eris village.

Eleven Species

The study was carried out to identify the parasite and causative diseases on cage reared tilapia at Bakerganj upazila, Barisal district. The infected tilapia fishes were collected from the cages and brought to the laboratory to find out signs, symptoms and infection area on the fish body. Physico-chemical parameters of water, such as water temperature, pH, dissolved oxygen, nitrate, phosphate and ammonia were monitored fortnightly. The values of water temperature (°C), pH, dissolved oxygen (mg/l), nitrate (mg/l), phosphate (mg/l) and ammonia (mg/l) were 32.4±2.1, 6.2±0.3, 7.52±0.4, 0.028±.008, 11.30±2.26 and 0.09±0.02, respectively but the concentration of nitrate was so higher during the study time. Eleven species of parasites namely, Chilodonella sp, Trichodiniasp., Gyrodactylussp.,Cichlidogyrus sp., Capillariasp, Orientocreadium sp, Eustrongylidae sp, Allocreadium sp, Euclinostomum sp, Tylodelphys sp. and Metagonimus spwere were identified. Parasites were found on all the examined parts of the fish body but gill showed the most infested area of the host. Highest mortality rate was occurred in the month of October and lowest mortality rate was in July. In this circumstance, proper management system and handling are best ways to prevent diseases and reduce the mortality rate of tilapia on cage farming in the southern area. Res. Agric., Livest.
