The Effect of Various Probiotics in Sangkuriang Cat Fish (Clarias gariepinus) on Health Status and Performans Production
Get PDFProbiotics are very important for cultivation because of their role in improving the health status of fish, increasing the body's resistance to disease, growth rate, improving intestinal morphology and balance of the microflora. The study aimed to compare commercial probiotics with probiotics from fermented milk using kefir seeds in an effort to improve health, growth rate and efficiency of sangkuriang catfish feed. The research material used 5-7cm long sangkuriang catfish as many as 400 tails. The study used a completely randomized design (CRD) with 4 treatments and 5 replications, namely P0:Control (feed without addition of probiotics), P1: Feed + 5% Probiotics A (King Grameh), P2: Feed + 5% Probiotics B (Em4), P3: Feed + 5% Probiotics C (Kefir). Each experimental unit consisted of 20 fish. The parameters observed in this experiment were growth rate, FCR and feed efficiency. Treatment with various types of probiotics has a significant effect (P <0.05) on FCR, feed efficiency, and growth rate. However, the FCR in treatments T1 and T2 did not show significant differences, and on feed efficiency and growth rate on T1 were not significantly different. The conclusion of this study is that the provision of kefir probiotics is able to show better production results

Health Conditions and Spatial Variations in Rhizophora apiculata Population Characteristics in the Petroleum Industry Area and Non-Industry in Riau Province
Get PDFThe current marine environment has begun to be polluted and will directly affect the biota around it. The study of health conditions and spatial variations in the characteristics of the population of Rhizophora apiculata was carried out in the mangrove ecosystem around the oil and non-industrial areas of Riau Province. This study aims at a baseline for evaluating mangrove management in Riau Province. Sampling is carried out using line transects drawn from the reference point (outermost mangrove stands) in a direction perpendicular to the coastline to the mainland and sample plots made with a size of 10 X 10 m2. Samples of leaves, fruits, and flowers are taken randomly based on the sample plots made. Then preserved with 70% alcohol and labeled. The preserved samples were taken to the laboratory to measure morphometrics and calculate the number of stomats. The results showed that the population of R. apiculata at all stations was in an unhealthy condition. In addition, individual competition and adaptability possessed by the population of R. apiculata are very low, ranging from 09.53 - 17.27% and illustrating more group growth and very high competition among individuals. Furthermore, the discriminant analysis shows that the morphometric variables that most characterize the population of R. apiculata in the oil industry with non-industrial areas are the length of the stem. Based on the results of PCA analysis, the variables that most determine the poor health of the population of R. apiculata are the parameters of Pb heavy metals, pH, temperature and DO waters
Reduction of Cypermethrin Residue in Jambal Roti of Giant Catfish (Arius Thalassinus Ruppell)
Get PDFJambal Roti is a dry-salted fish product made from Giant Catfish (Arius thalassinus Ruppell) with a bread-like texture when fried. This product was found to contain cypermethrin residue exceeding the BMR maximum limit determined by SNI and CAC. This study aimed to determine the best processing method to minimize the residue of cypermethrin in Jambal Roti products. A completely randomize experimental methosd was employed with five treatments and the replicates of each treatment. Treatments applied were A (washing the Jambal Roti for 1 minutes with running tap water), B (soaking in warm water at 50 ° C for 15 minutes), C (frying at 170 ° C for 10 minutes), D (washing with running tap water then fried) And E (soaking then fried). The residue of cypermethrin was analyzed gas chromatography prior and after the experimental treatments. Results indicated that all treatments were capable of reducing the cypermethrin content of the Jambal Roti. The highest percentage of the cypermethrin residue reduction was achieved by the treatment D in residual residuals in treatment D (washing with running tap water and then fried)
Sosio-Ecological Dynamic of Small Scale Fisheries in Prigi Trenggalek
Get PDFSmall scale fishing is a very important part of the fisheries sector. Not only play an important role in enhancing food security, but also becomes an absorbent for workers without the need for educational. Actors in the small-scale fishery, as defined by Law 45 of 2009, are fishermen who fish their daily needs with the largest size of 5 (five) Gross Register Tonnes (GT) of fishing boats. The fishermen of Prigi are dominated by small fishermen, where the fleet is no larger than 5 GT. The number of small-scale fishing gear in Prigi exceeds 60% of the total gear. The dominance of small-scale fisheries promotes good management with long-term goals, namely the sustainability of fisheries. Today's management of fisheries management has shifted from conventional management to community-based management. In order to support the community-based management of fisheries management, various information about the community, which is the policy objective, is needed. To this end, small-scale fisheries research in Prigi and strategies for the adaptation of the extended fishery fisheries were carried out. The method used is the snowball sampling method and the calculation of the diversity of catching resources. Fishermen who are the subject of the research are small-scale fishermen who operate ships under 5 GT. The gear is stretch fishing, gillnets and tonda fishing rods. There are small fishermen in Prigi who have different types of gear that are used at that time depending on the season of the fish. The selection of fishing gear by fishermen is likely to be caused by different expertise, skills and experience of fishermen in the operation of fishing gears. In addition, the capital held by fishermen to produce fishing gear and the economic level of the fish caught will also likely affect the fishers in choosing the type of fishing gear used each day. The adaptation strategies of fishermen to unpredictable catches are divided into two groups, namely the catch strategy and the search for alternative sources of income
