1. This program successfully cultivate Girella punctata 50 species of fish, while the development of incubators and breeding techniques to determine the optimal sex ratio Girella punctata, observe and record changes in the embryonic development of Girella punctata and each period of time, the establishment of food organisms feeding sequence, to serve as the basis of future breeding artificial incubation. 2. Establishment of Girella punctata completely edible algae growth, results are displayed in Cladophora fascicularis or Hypnea charoides feeding eight weeks after the beginning of the full-length less than 50 mm juvenile or early indicators of full-length 50 mm greater than the growth of juvenile fish begin feeding Cladophora fascicularis group better, also showed that Girella punctata can work as a clam eating fish pond algae silk. 3. The sum of the results of this project various growth indicators, growth rate of Girella punctata juvenile growth rates will vary and special dietary protein content increased and increased, and in 40% up to a maximum value began to decline after; feed conversion rates with protein content increases improved and began to rise to 40% of the optimal value; with the increase of the efficiency of the protein and the protein content of a downward trend. 4.First the total length of 46.08 ± 0.76 mm, initial weight 1.61 ± 0.06 g of Girella punctata and the beginning of full-length 53.13 ± 1.86 mm, initial weight 2.54 ± 0.06 g of Girella punctata white fish meal for animal feed protein source when all there at the time of the protein content of 40% best growth performance; polyline regression analysis to obtain the optimum growing demand for 41.98 percent protein and 41.41%. |
