Abstract
The technology of catfish cultivation, including hatcheries and enlargements, has been mastered by many people due to its relative ease. However, it is difficult for farmers to fulfill market needs due to high demand. An increased growth rate will play an important role in fulfilling this demand for catfish, and can be carried out with genetic engineering technology. Furthermore, easy-to-apply alternative genetic engineering for stimulating catfish growth involves the recombinant growth hormone, commonly called rGH (recombinant Growth Hormone). Therefore, this research aimed to evaluate the effect of rGH administration on catfish growth and survival performance. C. batrachus was treated with rGH through a combination of immersion and rGH feeding (oral boosting) method. The test animals used were catfish with an initial weight of 3.9 - 4.0 grams and an initial length of 7.21-8.11 cm with a maintenance period of 45 days. Furthermore, this research tested 4 treatments with 3 replications each, namely A (control), B (immersion), C (oral boosting feed), and D (immersion + oral boosting feed). The results showed that the administration of rGH gave the best results in the immersion + feed treatment (oral boosting), with a specific growth weight performance value of 4.27 4.31% .day-1, daily growth weight of 0.50-0.54 gram.day-1, daily growth length of 0.198-0.202 cm.day-1, feed conversion of 0.78 -0.82, and survival of 93.03-89.19%. Therefore, the provision of rGH through the immersion + feed method (oral boosting) increases growth performance and high survival rates
