The Effect of Adding Egg Shells to Moist Feed on The Specific Growth and Survival Rate of Lobster Panulirus sp
Full text linkSea lobster is a commodity that has high value in both national and international markets. Globally, the demand for sea lobster is increasing by about 15% per year. During growth, lobsters undergo a moulting process. Moulting/ecdysis is a very important process in the life cycle of arthropods (including decapods) because shell release is a must for growth and metamorphosis. In improving and assisting the molting process in lobsters, it is assisted by the provision of additional calcium from egg shells. Egg shells contain 94% calcium carbonate, 1% calcium phosphate, 1% magnesium carbonate and 4% organic compounds. In this study, an experiment was conducted on the addition of feed with a mixture of egg shells to support post-moulting optimization and supplement calcium requirements for lobster larvae. The percentage of egg shells as treatment, namely treatment A (0%), B (5%), C (10%), and D (15%) of the total feed to be made for sea lobster. Maintenance is carried out in a controlled tub, for four months. The highest specific growth obtained in this treatment was treatment A (0.06-0.21%) and the lowest was treatment D (-0.02%)-(-0.37%). Furthermore, the highest survival rate was obtained in treatment A (66.7%) and the lowest in treatment D (33.3%), the highest number of molting lobsters was in treatment A (77.8%) and the lowest was treatment D (33.3%). This shows that the addition of eggshell flour to moist lobster feed has not had a significant effect. For further development, it is necessary to research related to the use of additional ingredients in moist feed for lobster

Gen Transfer in Cultivation Shrimp Commodity
Full text linkGMO is a product of biotechnology through genetic engineering techniques. This can be done to increase food availability and reduce production costs, especially by manipulating the genes and chromosomes of cultivated species. In invertebrates such as shrimp, the application of gene transfer is still limited to the recognition and expression of foreign genes and focuses on increasing disease resistance. Among several gene transfer methods (microinjection, electroporation and transfection), transfection method is the most effective method to be applied to shrimp. It is characterized by high hatching data and is not toxic. In addition, the use of GMO in aquaculture is a highly controversial issue due to many environmental and health issues. This journal will discuss gene manipulation by means of gene transfer to improve shrimp culture
